Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, specifically to a molding die for plastic products. Background Technology

[0002] In the production process of plastic products, molten plastic solution needs to be injected into a molding mold. The shape of the inner wall of the molding mold is used to shape the plastic. It consists of several parts, and this assembly contains a molding cavity. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the molding cavity and cooled and shaped inside the cavity.

[0003] A search revealed a Chinese patent publication number CN220741996U, which discloses a plastic product molding die. In this patent, the cooperation between an ejector plate, a pull rod, and a spring allows the pull rod to be pulled upward, which in turn moves the ejector plate upward. The ejector plate then compresses the spring, simultaneously ejecting the plastic product from the lower mold. This achieves rapid demolding of the plastic product while maintaining its integrity.

[0004] However, when using the above-mentioned device, it is first attached Figure 2 As can be seen, the push plate 401 is in contact with the inner cavity of the lower mold 2, which means there is a gap in the inner cavity of the lower mold 2. There is a possibility of leakage when the plastic solution enters the inner cavity of the lower mold 2. Secondly, the attached drawing does not show how the cooling box is connected between the upper and lower molds. Finally, as can be seen from the attached drawing, because the push plate 401 is located at the bottom of the lower mold 2, it can only push the molded product that is difficult to detach from the inner cavity of the lower mold 2 to move it out, but cannot move the product that is difficult to detach from the inner cavity of the upper mold 3. In summary, the overall device is difficult to quickly detach the molded product and has poor practicality. Utility Model Content
