Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The application mould of antiseized master model, through set up a plurality of barbs all around at public mould benevolence inner wall, product sticky public mould benevolence side when preventing the die sinking, the barb volume that public mould benevolence side set up is less, can take off by force when the product is ejecting, can not exert an influence to the product, this type of mould structure has already wide application in the cosmetics industry and has produced, has improved production yield and production efficiency greatly, has reduced manufacturing cost.

The following detailed description is made with reference to the accompanying drawings 1 to 3 and specific embodiments.

The mold for preventing the female mold from being stuck comprises a female mold core and a male mold core 10 which is arranged below the female mold core and matched with the female mold core to mold a product 40, and is characterized in that a plurality of barbs 20 are arranged on the inner wall of the male mold core 10 corresponding to the female mold core, the barbs 20 extend along the central direction far away from the male mold core 10, and each barb 20 comprises a straight line part 21 and arc parts 22 arranged on two sides of the straight line part 21.

Referring to fig. 1 and 2, in this embodiment, the mold for preventing the female mold from being stuck includes a female mold core and a core insert 10. The male mold insert 10 is disposed under the female mold insert and matched therewith to form a product 40. A plurality of barbs 20 are arranged on the inner wall of the male mold core 10 corresponding to the female mold core. A plurality of the barbs 20 are grooves.
