Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, and particularly relates to a plastic mold with an anti - adhesion function. Background Art

[0002] Plastic molds are important tools in the plastic processing industry. They are used in conjunction with plastic molding machines to endow plastic products with complete configurations and precise dimensions. Plastic molds are combined tools for processes such as compression molding, extrusion molding, injection molding, blow molding, and low - foam molding. By forming a mold cavity, molten plastic is cooled and shaped to form plastic products of the required shape.

[0003] Currently, in the prior art, when most plastic molds perform the ejection operation, they only perform ejection through simple extrusion. If plastic adhesion occurs, ordinary ejection is likely to damage the product, resulting in a decrease in the product yield. In view of this, we propose a plastic mold with an anti - adhesion function. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a plastic mold with an anti - adhesion function, which can solve the problems raised in the above - mentioned technical background.

[0005] To achieve the above - mentioned purpose, the utility model proposes a plastic mold with an anti - adhesion function, including a device main body. A demoulding structure is arranged on the surface of the device main body. The demoulding structure includes:

[0006] A bottom plate. The upper surface of the bottom plate is fixedly connected with a lower mold. The upper surface of the bottom plate is fixedly connected with a hinge rod. The surface of the hinge rod is rotationally connected with the inner wall of a swing rod through a coil spring. The surface of the swing rod is slidably connected with the inner wall of a push rod. The surface of the push rod is fixedly connected with the surface of a push block. The surface of the push block is slidably connected with the inner wall of a push sleeve.

[0007] Preferably, a reed is fixedly connected to the inner wall of the push block. The surface of the reed is fixedly connected with the surface of a clamping block. The surface of the clamping block is clamped with the surface of a clamping tooth. The clamping tooth is opened on the inner wall of the push sleeve.

[0008] Preferably, the end face of the push sleeve is fixedly connected with the surface of a push plate. The surface of the push sleeve is slidably connected with the inner wall of the lower mold. The surface of the push sleeve is clamped with the surface of a main clamping block.

[0009] Preferably, the surface of the main clamping block is slidably connected with the inner wall of the lower mold. The surface of the main clamping block is fixedly connected with the surface of an elastic sheet. Both ends of the elastic sheet are fixedly connected with the inner wall of the lower mold.

[0010] Preferably, the device body includes an upper mold, a pressing plate is fixedly connected to the upper surface of the upper mold, and a material injection port is fixedly connected to the upper surface of the pressing plate.

[0011] Preferably, guide posts are fixedly connected to the surface of the pressing plate, and the surfaces of the guide posts are slidably connected to the inner wall of the bottom plate.

[0012] Beneficial effects

[0013] The present utility model provides a plastic mold with an anti-adhesion function. It has the following beneficial effects:

[0014] For this plastic mold with an anti-adhesion function, through the provided demolding structure, when it is necessary to demold the product, the upper mold is lifted, causing the swing rod to be reset by the coil spring. As a result, the swing rod drives the push block to move through the push rod, enabling the block to repeatedly squeeze and release through the reed and the teeth, thereby generating vibration for vibration demolding of the product in the lower mold. When the push block moves in place, the push block continues to push, causing the push sleeve to overcome the limit of the main block, thereby pushing the push plate to extrude the product from the lower mold. When the upper mold presses down on the swing rod, the push sleeve drives the push plate to reset, causing the main block to reset. When the upper mold presses down, the swing rod drives the push block to reset through the push rod, enabling the device to be reused. Description of the drawings
