    1 Device for molds where different working temperatures can occur between the mold halves of the mold tool.
    The present invention relates to a device for molds for preferably hot-channel injection molding of plastic materials, silicone, aluminum and similar materials or for molds where different working temperatures between mold halves can occur and which comprise guide-shaped movable mold halves.
    Kanda solutions of the specified type are complicated to manufacture and are thus costly. In the case of special hot duct spraying, but also with other mold tools which include mold halves where different working temperatures can occur, it is important that the mold halves are not displaced laterally with e.g. the negative result that the plastic details and other shaped details do not have such a beautiful mold surface on the outside, e.g.
    The main object of the present invention is thus to provide a device which i.a. compensates for the thermal expansion of the heated mold halyol in a molding tool and which solves the above problems, simply and efficiently and cost-effectively by requiring fewer parts to obtain a satisfactory result, that the accomplished bushing is cheap in addition to containing fewer parts, that it becomes simple and thus cheap to manufacture and that you can above all automate the manufacture of parts that are part of it, especially with an in-depth control that can also be manufactured to the desired length as needed. In addition, Onskas obtains good and precise precision on the said control despite temperature variations in the tool halves.
    Said means are achieved by means of a device according to the present invention which can mainly be characterized ddray, that said guides are arranged in 2 recessed recesses in each horn or in another suitable place in the heat extension direction of the mold, of the square square or rectangular shape, that the receiving recessed square shape receiving recesses are arranged jointly towards the center of the mold, whereby the heat demand a "of the tool is arranged to move in the direction substantially towards the center of the mold.
    The invention is described in the following as a number of preferred embodiments with reference to the accompanying drawings, in which Fig. 1 shows a schematic plan view of a half mold half seen from its one side, Fig. 2 shows a sectional view through a mold in mounted bearing showed a movable guide column according to a first embodiment, Fig. 3 shows a sectional view through a mold tool in mounted bearing showing a movable guide column according to a second embodiment, Fig. 4 shows a sectional view along the line IV-IV in Fig. 2, and Fig. 5 shows in partial sectional view a guide pin according to the invention.
    A device 1 for mold 2 which is intended for hot-channel injection molding of plastic materials, silicone, aluminum and similar materials or for molds where different working temperatures between mold halves can occur, and which comprise movable mold halves 3, 4 controlled by guides 5. According to the present invention, guides 5 arranged in recessed square, square or rectangular recesses 7 in the respective horns 6 or at another suitable place in the heat-extending direction of the mold of said shape or at another suitable place in the heat-extending direction of the mold 3 (8). Furthermore, the receiving of the said guides' first square-shaped square or rectangular receiving recesses 7 are arranged directed in a common direction 8, essentially towards the center 9 of the molding tool, against which the wire displacement of the tool, which i.a. ãr Achieved by spraying with hot plastic etc, is arranged to move.
    The said guides 5, which extend into the mold halves 3, 4 of the mold tool, are formed by a pin with a square-shaped square or rectangular skull 26, which is guided by square-shaped square or rectangular fitting receiving recesses 7.
    A screw 10 provided with threads 11, at least at its front end portion, is screwable and said guide-forming pin in a gangwayed hall 20 and is received by a stop 12 which is the hold of one mold half 3, clamped by a fixed plate 13 by means of a projecting flange 14 of the stop 12. This is clearly shown in Fig. 2.
    Fig. 3 shows a said screw 10, which pulls in from the outer end 5A of the guide 5 formed as a circular pin in a central hall 30 in the direction opposite to the screw shown in Fig. 2 in the guide 5, seen in the longitudinal extension 25 of the guide. The stop 12 shown in Fig. 3 has an internal aisle hall 15 with passages 16 into which the threads 11 of the screw 10 are screwed. This stop 12 abuts with its flange 14 in a recess 18 in one of the mold halves 3. The stop 12 is held in the embodiment shown in Fig. 3, fixed against rotation of a pin 19 received in a suitable transverse hall 21 in the first mold half 3 in the area of the flange 14 and the recess 18.
    According to both embodiments, said guide-forming pin is receptively guided in a bushing 22 and 4 is receptively guided in the second mold half 4 in its continuous hall 23.
    A fitting piece 24 selectable in the axial direction 25 to the desired lamella may be received between said stop 12 and the guide-forming pin 5 towards its square skull 26, which is received in a suitable recess 7 in the mold half 3, as shown in Fig. 3, whereby the desired distance A can be obtained.
    The guide-forming pin, which thus has a square, square or rectangular skull 26, has a circular cross-sectional shape on its guide, a front portion 27 projecting perpendicularly from the skull 26.
    The guide-forming pin 5 thus has a threaded hall 28 while the stop 12 has a through-hole 15 as shown in Fig. 2, or that, as shown in Fig. 3, the guide-forming pin 5 has a continuous central hall 30 while the stop 12 has a threaded hall 15, alit thus fitting to the diameter of said screw 10 and threaded portion respectively.
    The said guides are received in the associated receiving recesses 7 with sliding fit, seen in the direction of the heat dissipation direction 8 between the square-shaped skulls 26 of the guides 5 and its receiving recesses 7.
    The said receiving recesses 7 are formed by the recesses which extend through the ends of the associated mold halves in the corners of the mold half 3 or in another suitable place in the heat extension direction (8) of the mold.
    In said receiving openings there is provided a clearance X between the square or rectangular shaped shell of the pin, parallel end surfaces I, II and the spaced apart flat parallel opening end surfaces 100, 200, which are perpendicular to the said heat extension direction 8. See Fig. 4 the end surfaces III, IV and 300, 400, respectively, which are exposed in parallel with each other and with the heat retention direction, operate with a sliding fit and these surfaces show good tolerance and good surface roughness.
    A bushing 32 of the standard type is receivable in the tool 2 at a further fastening plate 33, which is bellows on the opposite side of the mold halves 3, 4.
    The function of the device 1 and the invention in general should have been apparent from the nature of the above-mentioned parts which are not described and explained. The drawings show tool 1 in the same direction.
    In the embodiment shown in Fig. 2, the screw 10 can be screwed for firm holding in the guide 5 by means of adhesive means of a suitable type, e.g. LoctiteTM. The length L of said guide 5 can also be chosen to fit the tool 2 and its size as required. The same applies to the possibility of selecting a suitable length A on a fitting piece 24 which is threaded on the screw at its front & ride between the stop 12 and the guide and its shell part 26.
    Furthermore, the forming pillar is arranged demountable, for example planar grinding of the mold halves 3, 4, whereby the same during assembly is arranged to be zeroed by means of a leaf mat or similar aids, so that the position of said pillar exactly matches the bushings of the lower mold half.
    The function and nature of the invention should have been clearly understood from the above and with knowledge even of what is shown in the drawings, but the invention is of course not limited to the embodiments described above and shown in the accompanying drawings. Modifications are possible, especially when it comes to the nature of the various parts, or by the use of equivalent technology, without departing from the scope of the invention as defined in the claims. 7
