A telescopic device for injection molds

Abstract

This utility model relates to a telescopic device for injection molds, belonging to the field of injection mold technology. It includes: a slide block, two sliders, and a telescopic mechanism. Two inclined blocks are fixed to opposite sides of the slide block, and each inclined block has an inclined groove on its side. Each slider has a limiting groove on its side wall. The two inclined blocks slide within the two limiting grooves, and the two sliders slide within their corresponding inclined grooves. The telescopic mechanism is located below the slide block, and its telescopic rod is fixed to the slide block to drive the slide block to move up and down reciprocally, causing the two sliders to reciprocate along the vertical direction of the slide block. This utility model first utilizes the inclined blocks to slide within the limiting grooves, and then utilizes the sliders to slide within the inclined grooves corresponding to the side walls of the limiting grooves. This provides dual guidance for the slider's sliding direction, improving the smoothness and stability of the slider's sliding without affecting the strength of the injection mold.

Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a telescopic device for injection molds. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it involves injecting molten plastic into a mold cavity under high pressure using an injection molding machine, where it is then cooled and solidified to obtain the molded product.

[0003] Currently, the telescopic device of injection molds consists of a hydraulic cylinder and a telescopic block. The telescopic block slides on the injection mold through a T-slot. The piston rod of the hydraulic cylinder is fixed on the telescopic block and can drive the telescopic block to move back and forth. However, the T-slot sliding structure reduces the strength of the mold and increases the difficulty of installing the telescopic block.

[0004] Therefore, how to design a telescopic device for injection molds that is simple in structure, easy to install, and does not affect the strength of the mold is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This utility model provides a telescopic device for injection molds, which solves the technical problems of difficult installation of telescopic blocks in existing injection molds and reduced mold strength.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a telescopic device for injection molds, comprising: a slide block, a slider, and a telescopic mechanism. Two inclined blocks are fixed on opposite sides of the slide block. Each inclined block is arranged from top to bottom in a direction away from the slide block, and each side adjacent to the slide block has an inclined groove arranged along the inclined direction. Two sliders slide within the injection mold along a direction perpendicular to the height of the slide block. Each slider has a limiting groove on its sidewall. The two inclined blocks slide within the two limiting grooves, and the two sliders slide within their corresponding inclined grooves. A telescopic mechanism is located below the slide block, and its telescopic rod is arranged along the height of the slide block. The telescopic rod is fixed to the slide block and drives the slide block to move up and down reciprocally, causing the two sliders to reciprocate along a direction perpendicular to the height of the slide block.

[0007] The beneficial effects of this utility model are: it improves the telescopic structure of the telescopic block of the traditional injection mold. First, the inclined block is used to slide in the limiting groove, and then the slider is used to slide in the inclined groove corresponding to the side wall of the limiting groove. This can guide the sliding direction of the slider in two ways, and improve the smoothness and stability of the slider without affecting the strength of the injection mold.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the bottom end of the slide is provided with a connecting groove with a longitudinal section of "T"; the top end of the telescopic rod of the telescopic mechanism has a "T" structure and is adapted to be inserted into the "T"-shaped connecting groove.

[0010] The further beneficial effect of adopting the above is that by using the top end of the telescopic rod of the telescopic mechanism to be fitted and fixed in the connecting groove of the T-shape, the stability of the connection between the telescopic mechanism and the slide can be improved.

[0011] Furthermore, the telescopic mechanism is a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod. Attached Figure Description

The telescopic mechanism 3 is located below the slide block 1 and its telescopic rod is arranged along the height direction of the slide block 1. The telescopic rod of the telescopic mechanism 3 is fixed on the slide block 1 and drives the slide block 1 to move up and down reciprocally, so that the two sliders 2 reciprocate and extend along the height direction of the vertical slide block 1.
