[0002] Injection molds are molds used for plastic injection molding. They can form plastic products with complex shapes, high dimensional accuracy or with inserts in one go. Injection molds are mainly composed of mold bases, mold cores, mold cavities, guide plates, ejector mechanisms, cooling systems, etc. The mold base bears the weight of the entire mold, while the mold core and mold cavity are responsible for forming the internal structure and external shape of the plastic product, respectively. In automobile manufacturing, the inner handle of the armrest requires an injection mold for molding operations.

[0003] The existing device has some disadvantages during use. For example, after the injection molding is completed, it is necessary to wait for the plastic part to be fully cooled and solidified in the mold before the demolding operation can be performed. In the prior art, the inner handle is generally demolded manually, and the demolding process is completed manually by the operator. Manual demolding usually takes a long time, especially when processing a large number of products. This efficiency problem is more prominent, so there is a problem of heavy labor load and low work efficiency. Utility Model Content

When the lower mold frame 12 moves to the center of the rectangular opening 13, the lower mold frame 12 is turned over by the rotating component, so that the material after injection molding falls into the conveying component below for transmission. The conveying component is responsible for transmitting the fallen material to the next process or collection point. This continuous and automated operation process greatly improves production efficiency and reduces the tediousness of manual operation.

[0020] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, the rotating assembly includes a driven gear 33 fixedly sleeved on the outer wall of the rotating rod 23 and a servo motor 30 fixed on the connecting plate 22.

The driving gear 32 is meshed and connected with the driven gear 33. During specific use, the rotating shaft 31 is driven by the set servo motor 30 to rotate, so that the rotating shaft 31 drives the driving gear 32 to rotate. The driving gear 32 is meshed and connected with the driven gear 33, so that the driven gear 33 and the driving gear 32 rotate synchronously, and the driven gear 33 drives the lower mold frame 12 to flip, so as to dump the material after injection molding.

[0021] As an implementation method in this embodiment, Figure 1 As shown, the injection molding assembly includes a cylinder 40 which is laterally symmetrically fixed on the workbench 10, and the piston end of the cylinder 40 is fixedly connected to a lower pressure plate 41, and the lower end surface of the lower pressure plate 41 is fixedly connected to the upper end surface of the upper mold frame 11, and the lower mold frame 12 is fixed to the upper end surface of the workbench 10.

[0023] As an implementation method in this embodiment, Figure 2 As shown, a vibrator 14 is fixedly installed on the side wall of the lower mold frame 12 . When the lower mold frame 12 is turned over, the vibrator 14 can be started to further speed up the demoulding speed to prevent the injection molded parts from sticking in the lower mold frame 12 .

[0024] Working principle: When in use, the electric slide rail 20 is started, and the slider 21 on the electric slide rail 20 drives the connecting plate 22 to move synchronously, so that the rotating rod 23 connected to the moving plate drives the lower mold frame 12 to move synchronously. When the lower mold frame 12 moves to the center of the rectangular opening 13, the servo motor 30 is used to drive the rotating shaft 31 to rotate, so that the rotating shaft 31 drives the driving gear 32 to rotate, and the driving gear 32 is meshed and connected with the driven gear 33, so that the driven gear 33 and the driving gear 32 rotate synchronously, and the driven gear 33 drives the lower mold frame 12 to flip, so as to dump the material after injection molding, so that the material after injection molding falls into the conveying assembly below for transmission, and the material is collected in the collection frame 53.
