Embodiment Construction
[0025] The present invention is described in detail below in conjunction with accompanying drawing:
[0026] The present invention can solve the problem of undercutting and ejecting the round product 7 in the case of insufficient space. The existing mold cannot be released smoothly when there are undercuts 71 inside the product, that is, it is impossible to make products with undercuts inside.
[0027] As shown in the figure, a special mold structure is used for forming and releasing the circular product 7 with an undercut inside, including the inner molding part 1 that cooperates with the lower part of the molding product and the inner part, and the middle part that is set outside the inner molding part 1. Forming part 2, the outer forming part 3 set outside the middle forming part 2, the upper end of the inner forming part 1 is provided with a lower forming groove 11 for forming the lower part of the circular product and an undercut forming groove 12 for forming the inner un...

The invention relates to a special die structure which comprises an inner forming part, a middle forming part arranged outside the inner forming part in a sleeving mode and an outer forming part arranged outside the middle forming part in a sleeving mode, wherein the inner forming part, the middle forming part and the outer forming part are matched together to form the lower portion and the inner portion of a product. The upper end of the inner forming part is provided with a lower forming groove used for forming the lower portion of a round product and an inverted covering forming groove used for forming the inverted covering inner portion of the round product, the upper portion of the inverted covering forming groove is provided with a lower limiting part making contact with the middle forming part to be used for limiting, the upper end of the middle forming part is provided with an upper limiting part making contact with the lower limiting part, the outer forming part is provided with a thread forming portion used for forming internal threads of the round product, and an upper forming part used for forming the upper portion and the outer portion of the round product is arranged above the inner forming part, the middle forming part and the outer forming part. The structure can be used for forming and mold stripping of the round product with the inverted covering inner portion, is relatively simple in structure and can ensure that the mold stripping of the product with the inverted covering inner portion is smooth.
Description
[0001] 【Technical field】 [0002] The present invention relates to a special mold structure. [0003] 【Background technique】 [0004] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specifi...
