Description

Mechanical buckling and supporting integrated mechanism for mold

Technical Field

The utility model relates to an injection mold, specific mechanical type knot that is used for mould props integrative mechanism that says so.

Background

The buckling machine and the supporting machine are two mechanical mechanisms commonly used for an injection mold, although the structural forms of the two mechanical mechanisms are different, the functions of the two mechanical mechanisms are the same, namely the buckling machine is used for controlling the delayed opening between the two mold plates, and the supporting machine is used for controlling the delayed closing between the two mold plates. For dies of medium and above specifications, the use of a sear or prop is generally in groups of four to ensure the reliability and stability of the delayed opening or delayed closing action. However, in practice, the situation of sequential delayed opening or delayed closing between three mold plates is often encountered, and if a traditional button machine and a traditional support machine are adopted, at least four button and support machines are required to be installed on the same set of mold, so that the manufacturing cost of the mold is increased, the space on two sides of the mold is crowded, the installation or connection of other functional parts is influenced, and the size of the mold is even increased.

Wherein: 1-A plate, 2-B plate, 3-rear supporting plate, 4-pin shaft, 5-buckle rod piece, 6-brace rod piece, 7-spring, 8-slide block, 9-box base and 10-box cover.

Detailed Description

In order to enhance the understanding of the present invention, the present invention will be described in detail with reference to the following embodiments and the accompanying drawings, wherein the embodiments are only used for explaining the present invention, and do not limit the protection scope of the present invention.

As shown in figure 1, the utility model relates to a mechanical buckling and supporting integrated mechanism for a mold, which comprises a box base 9, a box cover 10, a plate A1, a plate B2 and a rear supporting plate 3, wherein the plate A1 and the rear supporting plate 3 are arranged at two sides of the plate B2, a screw passes through the box cover 10 and the box base 9 and is fixed on the plate B2, the box cover 10, the box base 9 and all parts of the mechanism form the buckling and supporting integrated mechanism, a pin shaft 4, a sliding block 8 and a spring 7 are arranged in the box base 9, one end of the spring 7 is contacted with the sliding block 8 and pushes the sliding block 8 to move left, the other end of the spring 7 is tightly fixed by the screw, one end of a buckling rod part 5 of a delay plate A1 and a plate B2 extends into the box base 9, the lower end inclined plane of the buckling rod part 5 is contacted with the inclined plane of the sliding block 8, a side arc groove of the buckling rod part 5 is matched with the pin shaft 4, the other end of the buckling rod part 5 is tightly fixed on the plate A1 by the screw, the other end is fastened on the rear supporting plate 3 by a screw, one side of the upper end of the stay bar piece 6 is provided with a side step surface, and the other side is provided with an inclined surface.

When the mold is opened, the buckling rod piece 5 cannot move under the limitation of the pin shaft 4, the A plate 1 and the B plate 2 are locked, the stay rod piece 6 moves downwards, the B plate 2 is separated from the rear supporting plate 3, when the inclined surface of the upper end of the stay bar member 6 moves down to contact with the pin shaft 4, a space for the pin shaft 4 to move rightward begins to be formed, when the pin shaft 4 moves out of the arc-shaped groove on the buckling rod piece 5 rightwards, the locking function of the buckling rod piece 5 disappears, the B plate 2, the rear supporting plate 3 and other parts of the mechanism except the buckling rod piece 5 move downwards together to realize the separation between the A plate 1 and the B plate 2, and the die sinking between the B plate 2 and the rear supporting plate 3 is completed, the side step surface at the upper end of the stay bar piece 6 moves downwards to exceed the bottom surface of the slide block 8, the slide block 8 slides leftwards under the push of the elasticity of the spring 7 to form a clamping position, and the whole die opening process is completed when the A plate 1 and the B plate 2 are pulled apart to a set distance.

When the die is closed, the slide block 8 moving leftwards and the step surface at the upper end side of the stay bar piece 6 form a clamping position, the stay bar piece 6 cannot move upwards, the B plate 2 and the rear support plate 3 are supported, and only the B plate 2, the rear support plate 3 and other parts of the mechanism except the buckle bar piece 5 move upwards together, so that the A plate 1 and the B plate 2 are closed in advance; when the lower end inclined plane of the buckling rod piece 5 is contacted with the corresponding inclined plane of the sliding block 8, the sliding block 8 moves rightwards gradually under the action of mold closing force until the mold closing between the A plate 1 and the B plate 2 is finished, the sliding block 8 moves rightwards and moves back, the clamping effect disappears, and the arc-shaped grooves on the buckling rod piece 5 synchronously return to form a leftwards moving space of the pin shaft 4; at the moment, the die assembly is started between the B plate 2 and the rear supporting plate 3, the stay bar piece 6 moves upwards, the inclined surface at the upper end of the stay bar piece 6 pushes the pin shaft 4 to move leftwards into the arc-shaped groove on the buckle bar piece 5 and is limited by the side straight surface until the die assembly is finished.
