    • 专利摘要:
    A latch for a mold having an inner mold part sandwiched between fixed and movable outer mold parts comprises a pair of bars each mounted on a respective one of outer mold parts and a locking pin mounted on the inner mold part but displaceable thereon in a direction perpendicular to the direction of motion of the mold parts during opening and closing. One of the bars is formed with a seat in which the pin is snugly engageable when the respective outer mold part is snugly engaged with the inner mold part, and the other outer mold part can only move against the inner mold part when this pin is seated in the recess as otherwise it blocks a control surface of the bar of the outer mold part. A bolt provided in the inner part is also slideable to block displacement of the other outer mold part toward the inner mold part until the one outer mold part is relatively closely juxtaposed with the inner mold part and a control surface of the respective bar cams the bolt out of the way of the other part.

    (54) DEVICE FOR LOCKING THE FORM OF THE CASTING UNDER PRESSURE
    The invention relates to foundry, in particular, to injection molding. It is known a device for locking a mold to be cast under pressure, which has two two planes of the connector. The device contains a guide bar, rigidly fixed in a fixed form plate, a connecting bar with a rocker spline, hinged. in a movable plate, and a connecting pin secured in the intermediate plate perpendicular to the direction of movement of the plates. When locking the form, the connecting j enters the link slot of the connecting strip “
    A disadvantage of the known device is that its nodes in the process of work are subject to great wear.
    The purpose of the invention is to increase the service life of the device.
    This goal is comprehended by the fact that the connecting bar is rigidly fixed in the movable plate of the mold, 25 and the connecting finger is placed between the planks and is mounted for movement in the direction perpendicular to the direction of movement of the plates.
    The device can be equipped with a removable console fixed to the intermediate plate, it is advisable to install the connecting pin in the removable console and in the latter in the direction of movement of the plates perform a through-hole of rectangular cross section, the surfaces of which are guides for the slats.
    The console can be made supporting holes for the connecting finger, having an oval shape.
    The device can be equipped with a spring-loaded lock installed in the console perpendicular to the direction of movement of the plates and acting with the guide and connecting bars.
    It is advisable to make the latch in the form of a V-shaped frame, open in the direction perpendicular to the direction of movement of the plates.
    At one end of the V-shaped retainer frame and on the guide bar can be made for interaction, resistant surfaces directed perpendicular to the direction of movement of the plates, and at the other end of the V-frame retainer l on the connecting bar can be made for interaction inclined surface.
    It is advisable to install the connecting pin rotatably around its longitudinal axis.
    FIG. Figure 1 shows schematically an apparatus for locking a mold with two planes of a plug; in fig. 2 the same, at the stage of opening the shape along the first plane of the connector; in fig. 3 and 4 - the same, in the step of opening the forg / 5Y along the second plane of the connector; in fig. 5 - device in isometric projection.
    The device contains a guide bar If the connecting bar 2, the console 3 and the connecting finger 4. Directing the cad 1 is rigidly fixed on the fixed plate 5 of the mold to be cast under pressure. The supporting strip 2 is rigidly fixed in the movable plate 6. On the intermediate plate 7, consisting of a package of molding plates 8 and 9, a con- is fixed. salt 3. Between the plates 5 and 7 is the first plane of the connector A, and between the plates 7 and B is the second plane of the connector B of the form.
    The guide plate 1 has, on the side facing the connecting plate 2, a guide surface 10, to which an abutment surface 11 adjoins, parallel to the direction of movement of the form plates. The guide surface 10 is inclined to the direction of movement of the plates.
    The connecting strip 2 has a recess 12 into which the connecting pin 4 partially slides. The finger 4 can move freely in the direction perpendicular to the direction of movement of the plates and rotate around its axis. For this purpose, support holes 13 having an oval shape are made in the console. In the console 3, the through hole 14 of the rectangular cross-section of the surface 15 and 16 of which is made in the direction of movement of the plates is for the strips 1 and 2, the guide and connecting strips 1 and 2, which have a rectangular shape, are tightly attached to the direction Cimim Surfaces 16 OWN GUIDE SURFACES 17 1 18. The side surfaces of the plan are adjacent to the guides of the concol 3.
    In-console 3 is installed lock
    19, the shape of the V-shaped frame, open in the direction perpendicular to the direction of movement of the plates. The retainer has a stubborn surface.
    20, which corresponds to the abutment surface 21 on the guide bar 1. The connecting bar has a guide surface 22 serving to unlock the latch 19. The clamp is pressed by the spring 23.
    The device works as follows.
    During the metal pouring process, the mold is in a locked state. When the mold is opened, as soon as the fastening plate 24 moves to the right, the mold will open along the plane of the connector A, the rods will be removed (the rods are not shown in the drawings). The support surface 11 of the guide plate 1 continues to contact the cylindrical surface of the connecting pin 4, which holds it in the recess 12 of the connecting strip 2. Thereby, the connection between the stack of plates 8 and 9 and the movable plate 6 is maintained. In FIG. Figure 3 shows the position when the plates 6, 8 and 9 have moved away from the fixed plate 5, and the connecting finger is freed from the support surface 11 and partially leaves the notch 12. As a result, the mold begins to open along the plane B of the connector. Between the front end of the interposer 2 and the guiding surface 10 of the bar 1, a slide 25 is formed. In FIG. 4, it can be seen that the connection between the stack of plates 8 and 9 and the movable plate is completely removed. The mold is opened along two planes of the connector, the casting is removed from the mold (in the plane B of the connector).
    The closure of the form is carried out in reverse order. When moving the fastening plate 24 to the left, the plate 25, formed between the guide surface 22 of the interposer 2 and the guide surface 10 of the direction of the bar of the bar 1, pushes the connecting pin 4 into the recess 12. Upon further movement, the thrust surface 11 of the bar 1 hits the finger 4 and sinks it into the groove 12.
    In an emergency situation, for example, when the gates enter the slot B or the casting hangs, the mold on this connector does not close immediately. This can lead to premature withdrawal of the plates 7 in the direction of the fixed plate 5, unhindered entry of the bar 1 into the opening of the console 3, and then the bar 2 and jamming the latter between the connecting finger 4 and the direction of the 16 of the hole of the console 14 3 The locking mechanism excludes such a situation, it is under the action of the springs 23 enters the opening of the console and its thrust surface 20 is aligned with the thrust surface 21 on the guide bar 1. In FIG. 4 shows a position where a short distance remains between surfaces 20 and 21; .
