[0002] Injection molding is a method for producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding also includes rubber processing, which means that two plastic materials are not necessarily injected on the same injection molding machine, but molded in two times; after the product is removed from one set of molds, it is placed in another set of molds for a second injection molding.

The automatic blanking fixture for injection molding of circular injection molded parts solves the problems of existing automatic blanking fixtures for injection molding of circular injection molded parts, such as inconvenient clamping, high clamping cost, and inconvenience in adjusting the height of the injection molded parts. However, in actual use, when the component of the fixture fixing the mold is loosened for blanking or demolding, gravity automatically falls off and easily damages the injection molded parts. A structure that can automatically eject the injection molded parts is required to avoid damage to the injection molded parts and improve safety. Therefore, it is very necessary to design an automatic demolding fixture for injection molded parts. Utility Model Content

An L-shaped plate 7 is rotatably connected to the outer surface of the rotating rod 6. The L-shaped plate 7 is slidably connected to the first adjustment rod 4;

[0025] In this embodiment, the other end of the L-shaped plate 7 is slidably connected to a second adjustment rod 8. A slider 9 is fixedly connected to the outer surface of the second adjustment rod 8. The slider 9 is slidably connected to the fixed block 5. A support rod 10 is fixedly connected to the upper surface of the adjustment frame 1. An injection moulding table 11 is fixedly connected to the upper surface of the support rod 10. A second electric telescopic rod 12 is fixedly connected to the middle of the fixed block 5. The output end of the second electric telescopic rod 12 is fixedly connected to a top block 13.

[0026] During specific use, the adjustment frame 1 is fixed with a rotating rod 6 through the fixed block 5. An L-shaped plate 7 rotates on the rotating rod 6. The first electric telescopic rod 2 is started to perform telescopic adjustment of rising and falling within the adjustment frame 1, so that the first adjustment rod 4 on the adjustment block 3 drives the L-shaped plate 7 to be adjusted. In cooperation with the second adjustment rod 8, the slider 9 moves closer to or away from on the injection moulding table 11 fixed by the support rod 10, realizing the combination of the moulds. After injection moulding, the second electric telescopic rod 12 is started to drive the top block 13 to eject. Since the size of the top block 13 is smaller than that of the mould, it directly completes automatic demoulding without being blocked by the mould shell. The top block 13 ejects the injection moulded part to facilitate demoulding, avoiding the injection moulded part from being damaged due to direct demoulding under gravity and improving safety.

[0027] In this embodiment, a limit post 14 is fixedly connected to the upper surface of the slider 9. A connecting plate 15 is sleeved on the outer surface of the limit post 14. One end of the connecting plate 15 is fixedly connected to a half mould 16. The half mould 16 is fixedly connected to the injection moulding table 11.

[0031] In this embodiment, adjustment grooves 18 are symmetrically arranged on the upper surface of the adjustment frame 1, and the size of the L-shaped plate 7 is smaller than that of the adjustment grooves 18.

[0032] During specific use, when the L-shaped plate 7 drives the slider 9 to adjust, there will be a position movement. The adjustment grooves 18 can enable the L-shaped plate 7 to move better without being hindered.

[0033] In this embodiment, a protection column 19 is fixedly connected to the outer surface of the first electric telescopic rod 2.

[0034] During specific use, the protection column 19 protects the safety of the first electric telescopic rod 2 and prevents the first electric telescopic rod 2 from being damaged.

[0035] In this embodiment, a power storage block 20 is fixedly connected to the lower surface of the protection column 19.

[0036] During specific use, the power storage block 20 stores electricity to supply normal power consumption for the fixture.

[0037] In this embodiment, an anti-slip pad 21 is fixedly connected to the lower surface of the power storage block 20.

[0038] During specific use, the anti-slip pad 21 increases the friction at the contact with the ground and improves safety.

[0039] Working principle: During use, the adjustment frame 1 is fixed with a rotating rod 6 through a fixing block 5. The L-shaped plate 7 rotates on the rotating rod 6. The first electric telescopic rod 2 is started to perform telescopic adjustment of rising and falling within the adjustment frame 1, so that the first adjustment rod 4 on the adjustment block 3 drives the L-shaped plate 7 to adjust. Cooperating with the second adjustment rod 8, the slider 9 moves closer to or away from on the injection molding table 11 fixed by the support rod 10 to realize the combination of the molds. After injection molding, the second electric telescopic rod 12 is started to drive the ejector block 13 to eject. Since the size of the ejector block 13 is smaller than that of the mold, it can directly complete automatic demolding without being hindered by the mold shell. The ejector block 13 ejects the injection molded part to facilitate demolding, avoiding the injection molded part from being demolded directly under gravity and being damaged, improving safety. The limit column 14 can limit the half mold 16 connected by the connecting plate 15, facilitating it not to be affected by deviation during the movement. The limit column 14 can connect and fix half molds 16 of different sizes for injection molding, improving applicability. Through the through hole 17, the second electric telescopic rod 12 can be repaired and detected, and at the same time, the heat generated by it can be dissipated. The protection column 19 protects the safety of the first electric telescopic rod 2 and prevents the first electric telescopic rod 2 from being damaged. The anti-slip pad 21 increases the friction at the contact with the ground and improves safety.
