Description

Mould for demoulding without damaging products Technical Field The utility model belongs to the technical field of dies, and particularly relates to a die capable of demolding products without damaging the products. Background The injection mold is a tool for producing plastic products, and also a tool for endowing the plastic products with complete structures and precise dimensions, and the injection molding is a processing method used for mass production of parts with complex shapes, specifically, the injection mold is used for injecting heated and melted plastic into a mold cavity at high pressure by an injection molding machine, and cooling and solidifying are carried out to obtain the formed products. The existing injection mold generally adopts an injection port to directly inject raw materials into a mold cavity for molding, when the product is in a rectangular frame and other structures, the situation that the local part of the injection molding is uneven easily occurs when the integral mold channel of the mold cavity is long is encountered, and the injection mold has only one injection port, after the product is molded, the product is only clamped between the mold channels of the upper mold and the lower mold, the bonding degree of each part of the product and the mold channels of the upper mold and the lower mold is different, the whole product is pulled by uneven force between the upper mold and the lower mold during mold opening, and when the product is a thin and narrow frame product, the situation that the product is bent and kinked due to demolding easily occurs.
