Description

Technical Field

[0001] The utility model belongs to the technical field of demoulding plastic molds, and relates to an automatic demoulding plastic mold which can prevent finished products from falling off. Background Art

[0002] Plastic stamping dies are important tools for producing plastic products. Plastic materials are placed in the mold and then punched by a punching machine to form the plastic material in the shape of the mold, and finally the desired plastic product is obtained. Plastic stamping dies play a vital role in the manufacturing process. They are responsible for shaping the original plastic material into products of various shapes and sizes. However, when the mold cannot effectively prevent the plastic parts from falling off during the demolding process after the stamping is completed, a series of problems will arise.

[0003] Dropped plastic parts may be deformed by the impact, resulting in inaccurate size, distorted shape, or even cracking. This not only affects the appearance quality of the product, but more importantly, it may damage the functionality and performance of the product.

[0004] If the dropped parts need to be picked up manually after each stamping, it will not only increase the labor intensity of the workers, but also cause the production line to stop, thus reducing production efficiency. In addition, frequent picking and placing of parts may also lead to operational errors, further reducing production efficiency.

[0005] This not only increases production costs, but also may put pressure on the environment if too many discarded parts are discarded. In addition, if the production line is stopped due to product damage, additional equipment depreciation and labor costs will be incurred. Therefore, an automatic demoulding plastic mold that prevents finished products from falling is urgently needed to solve the above problems. Utility Model Content
