专利摘要:
A device including an injection mold for the production of a boot from thermoplastic material, the boot having a boot shank of a color different from that of the shank flange and the outer sole, both of which have the same color, by molding the shank and then in a subsequent and simultaneous step, molding the upper shank flange and the outer sole onto the molded shank. The injection mold includes a last for fitting with a textile sock, a base stemple having a deadhead borehole for injection molding the outer sole, another base stemple having a deadhead borehole for molding the shank, and two sidepieces. The sidepieces having sliding elements and, in their closed position for molding the upper shank flange, accommodate at least one deadhead borehole which communicates with the deadhead borehole of the base stemple for the outer sole. The sliding elements cover the cavity for the upper shaft flange during the molding of the shaft and release it for the molding of the upper shank flange.

专利说明:

The invention relates to the manufacture of shoes from a polymeric material and is intended to be manufactured by injection molding from a thermoplastic material boots with the tops of a different color than the upper part of the leg and the sole.
The purpose of the invention is to expand the technical capabilities of the device by enabling the manufacture of boots with excellent tops and soles of DT tops.
N.ch FIG. 1 depicts the proposed device with several workplaces; in fig. 2 is a view of L in FIG. one; on fig.Z - block with overlapping elements; 4 shows the side parts and bottom elements (a section along the E0 plane shaft in FIG. 3); Fig; 5 shows a section K-B in Fig. 4; Fig. 6 shows the device in the leg forming position; figure 7 - section Vna 6; Fig. 3 shows a device in the position of forming the upper part of the shaft and the sole; figure 9 is a section of the GG on Fig.
Devices for the manufacture of boots by injection molding of thermo-plastic material contains a rotating (ice table 1, on which working positions 2 are mounted, each of which includes forming a cavity 3 block 4 for pulling the textile layer of the boot, detachable side parts 5 and 6 for forming the tops and alternately interacting with their ends two bottom elements 7 and 8 for forming the bottom of the boot and the bottom plate, respectively. The bottom element 7 has a sprue channel 9, and an element 8 has a sprue channel 10.
Near table 1, tools 11 and 12 are installed for injection molding thermoplastic materials of different composition and color.
The block 4 is connected via a coupling (not shown) to the holder 13 and has a prism-shaped support 14 for centering the side portions 5 and 6 in the working position.
The device is equipped with a device for forming the upper part of the shaft, mounted with the possibility of axial movement. 11cblind to form the upper part of the tops of the upper in the form of overlapping elements 15 and 16, kain elec

The overlapping elements 15 and 16 are pivotally connected to a common driving rod 21 by means of movable arms 22 and 23 and pivotally connected to them with the cylindrical fingers 24 and 25 located in the slots 26. The driving rod 21 is housed in the block 4.
The wedge members 17 and 18 are placed in the side portions 5 and 6, respectively, and are made with a stepped wedge surface, the step 27 of which is designed to hold the sliding forming members 19 and 20 into the working position, and the step 28 to keep them in the off position when the leg is formed without top.
Sliding forming elements 19 and 20 are spring-loaded relative to the wedge elements 17 and 18 in the radial direction.
The side parts 5 and 6 are provided with control rods 29 and 30, which are connected at one end to their corresponding wedge element 17 and 18. The second ends of the rods 29 and 30 are made by the ends 31 and 32 of the side parts facing the bottom element. 5 and 6. Springs 33 and 34 of compression are placed between the side parts 5 and 6 and the rods. Under the protruding ends of the rods 29 and 30 in the bottom element 7 made grooves 35 and 36.
In order to manufacture boots with an upper leg and a sole different in color from the shaft and a sole, the device is equipped with at least one additional sprue channel 37 or 38, formed in the side portion 6 for joining the cavity of the bottom element 8 for shaping the sole by molding the upper leg. To form a transitional zone between the colored parts of the shaft, the pere-. the covering elements 15 and 16 are chamfered 39 and 40 in internal diameter.
Formucation elements 19 and 20 are moved along guides 41 (Fig. 5) and held in the working position by compression springs 42.
The device works as follows.

. 1t making the boot on the pad 4, the textile layer of the boot in the form of a stocking first tenses, and lateral parts 5 and 6 are brought to the pad 4 (Fig.6). In this case, the overlapping elements 15 and 16 are pressed against the block 4, overlapping zone 43 (FIG. 3) for forming the upper part of the boot of the boot, and the forming elements 19 and 20 are located between and wedge level 28 of the lower elements 17 and 18, squeezing springs 42. Next, the bottom element 7 is rotated to the ends 31 and 32 of the side parts 5 and 6 and fastened with them (the means for fastening are not shown). During the rotation of the element 7, the free ends of the rods 29 and 30 enter into its notches 35 and 36. At the same time, the wedge elements 17 and 18 are slightly displaced axially by the amount S), ensuring that the steps 28 interact with the outer wedge surface of the forming elements} 1t 19 and 20, the locking of the overlapping elements 15 and 16 with a block 4.
Through the sprue channel 9, the material is fed into the cavity 3 to form the lower shaft and the foot part of the boot. In this position of the device, the channels 37 and 38 are closed at one end by the bottom element 8 (Fig. 7) and from the second - by the overlapping elements 15 and 16.
After the molded part has cured, the bottom part 7 is retracted from the side parts. As a result, the control rods 29 and 30 with the wedge elements 17 and 18 return to their original position (Fig. 4), releasing the overlapping elements 15 and 16. The latter are displaced axially with respect to the pad through the shank 21 in the direction from the forming cavity 3 (see Fig. 8), and a bottom element 8 is supplied to the ends 31 and 32 of the side portions 5 and 6 for forming the sole. The latter, acting on the free ends of the rods 29 and 30, causes the latter, together with the wedge elements 17 and 18, to axially move in the direction towards the overlapping elements until the interaction of the stages 27 with the conical outer iru-surface of the elements 19 and 20.

kg 4 to form the cavity 44 for forming the upper part of the tibia- u (a. The cavity 44 communicates through the additional channels 37 and 38 with the cavity of the bottom element 8 for molding the sole (Fig.9) and block the thin transition zone at the upper part of the shaft, formed due to the presence of chamfers 39 and 40 on the overlapping elements 15 and 16.
Through duct 10, thermoplastic material, different in color from the leg material, is fed to form the upper leg and sole.
After the molded parts of the boot have hardened, the bottom element 8 is retracted from the side portions 5 and 6, the latter are set apart, releasing the pad, and the finished boot is removed from the pad 4. The next textile stocking layer of the boot pulls on the pad 4 and the process repeats.
The proposed device allows to significantly speed up the process of manufacturing boots with excellent upper and lower parts in color from the tops and to obtain high quality boots, as it provides a clear line between materials of different colors.
