Abstract

The invention relates to the field of injection molding equipment, in particular to an injection mold for molding of bottles. The injection mold for molding of the bottles comprises a mold body provided with a female mold and a male mold, wherein the female mold is slidably connected with the mold body and is detachably connected with the male mold; the female mold comprises two movable molds which are arranged oppositely; the two movable molds are detachably connected with each other and can slide on the mold body in the mold opening direction in a reciprocating manner; the male mold comprises a flexible mold bag and a filling device for controlling shrinkage and expansion of the mold bag; the filling device is arranged on the mold body; the mold bag is positioned between the two movable molds and is connected with the mold body; and a mold cavity is formed between the movable molds and the mold bag. According to the injection mold for molding of the bottles, the size of the mold bag is controlled by filling to control the wall thickness, the cooling time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to an injection mold for bottle molding. Background technique [0002] At present, bottle-shaped plastic products, especially those with a small mouth and a large body, cannot be ejected normally, so they are generally produced by blow molding. The specific method is to first inject a tube blank with an ordinary injection molding machine , the bottle head part (bottle mouth, thread) of the tube blank has been formed, and then the worker puts the tube blank on a honeycomb heater or an automatic circulation heating conveyor belt to heat and adjust the temperature, and then moves it to the blow molding machine and blows it with compressed air. type. One of the problems existing in the prior art is that it is difficult to control the wall thickness of blow-molded products, and it is impossible to produce products that require wall thickness. The second problem in the prior a...
