Description

Technical Field

[0001] This utility model belongs to the field of core-pulling and demolding technology, specifically relating to a three-stage core-pulling and demolding mechanism for multi-channel tubes. Background Technology

[0002] With the development of industrial technology, the structure of injection molded products is becoming increasingly complex, and the traditional mold structure is becoming increasingly difficult to meet the ever-changing product requirements.

[0003] When opening an injection mold, for products with long cores and multiple core-pulling requirements, one-time core pulling cannot meet the product demolding needs. Two or even three core pulling must be used. Therefore, a safe, reliable, simple and convenient three-stage core pulling mechanism with a slider is required. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-tube three-stage core pulling demolding mechanism, which has the advantage of facilitating core pulling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-tube three-stage core-pulling demolding mechanism, comprising a plastic product, wherein the plastic product is equipped with a demolding machine, the demolding machine comprising a first core-pulling assembly, a second core-pulling assembly, a third core-pulling assembly, and a slide rail; the first core-pulling assembly comprises a first hydraulic cylinder, the sliding end of the first hydraulic cylinder being fixedly connected to a slide block, the outer wall of the slide block being fixedly connected to a first sliding block; the second core-pulling assembly comprises a first limiting screw and a second limiting screw, the outer walls of the first limiting screw and the second limiting screw being fixedly connected to a guide rail, the outer wall of the guide rail being fixedly connected to a second sliding block; the third core-pulling assembly comprises a third sliding block, the outer wall of the third sliding block being fixedly connected to a stop pin; the demolding machine further comprises a first slider, a second slider, a third slider, a fourth slider, a fifth slider, and a third hydraulic cylinder, the sliding end of the third hydraulic cylinder being fixedly connected to the second slider; the first slider, the second slider, and the third slider surround the outer side of the plastic product.

[0006] With the above technical solution, after the A / B plate is opened, the slide block and the first sliding block move backward under the drive of the first hydraulic cylinder. This is the first core pulling. After moving 26mm under the action of the first and second limit screws, the guide rail moves backward again, and the second sliding block moves downward. This is the second core pulling. At this time, the third sliding block is stationary. When the second sliding block is completely disengaged from the undercut, the third sliding block is moved backward until the first and third sliding blocks are completely disengaged from the product. The third core pulling is completed. Before the mold is opened after injection molding, the second hydraulic cylinder drives the sixth slider of the front mold to pull the core obliquely. After the slider is completely disengaged from the product, the parting surface opens again. At the same time, the third, fourth, and fifth sliders achieve the slider demolding and core pulling action under the action of the oblique guide post. Finally, the first and third hydraulic cylinders move simultaneously, driving the first and second sliders to complete the core pulling. Finally, the product is ejected, and the mold opening action is completed. This can achieve a fixing effect. The first, second, and third sliders surround the outside of the plastic product and can fix the T-shaped pipe, thus facilitating processing.

[0007] Preferably, a second oil cylinder is provided on the top of the demolding machine, and a sixth slider is fixedly connected to the sliding end of the second oil cylinder.

[0008] The above technical solution can achieve the effect of control, and the movement of the sixth slider can be controlled by the second oil cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. After the A / B board is opened, the slide block and the first sliding block move backward under the drive of the first hydraulic cylinder. This is the first core pulling. After moving 26mm under the action of the first and second limit screws, the guide rail moves backward again, and the second sliding block moves downward. This is the second core pulling. At this time, the third sliding block is stationary. When the second sliding block is completely disengaged from the overlock, the third sliding block is moved backward again until the first and third sliding blocks are completely disengaged from the product. The third core pulling is completed.

[0010] 2. Before the mold opens after injection molding, the second oil cylinder first drives the sixth slider of the front mold to pull the core at an angle. After the slider is completely separated from the product, the parting surface opens again. At the same time, the third, fourth and fifth sliders, under the action of the inclined guide pillars, realize the slider demolding and core pulling action. Finally, the first and third oil cylinders are pulled at the same time, driving the first and second sliders to complete the core pulling. Finally, the product is ejected, and the mold opening action is completed. Attached Figure Description
