Abstract

The invention provides a plastic injection mold for a composite cap overturning bottle cap. The plastic injection mold comprises a mold frame structure assembly, a runner material releasing assembly, a molding assembly, a front mold ejecting out assembly, a thread releasing mechanism assembly and a mold opening sequence control assembly. A gating system is designed into the manner that feeding is carried out from the center of a product through a pin-point gate, and the mod is provided with eight cavities. The ejecting out manner that gas enters from a gas nozzle to carry out gas ejecting is finally adopted. According to the technical scheme, the front mold ejecting out assembly, the thread releasing mechanism, the read mold ejecting mechanism and the improved type mold structure are designed oriented to the problems that in an existing mold technology, an overturning cap sticks to a front die and cannot be completely ejected out in a full-automatic manner in the ejecting out process, manual auxiliary mold releasing is needed, and consequently the mold production efficiency is low; thus, defect-free automatic molding production of the product is achieved, and the product forming quality is effectively ensured; and the plastic injection mold is reasonable in structure design, stable in work, safe and reliable.

Description

technical field [0001] The invention relates to the field of mechanism design of injection molds, in particular to an injection mold for composite flip cap bottle caps. Background technique [0002] Such as figure 1 As shown, when plastic bottle caps with flip caps are injection molded, the problems existing in the existing mold technology are that the flip caps stick to the front mold, and cannot be fully automatically ejected during ejection, and manual assisted demoulding is required, resulting in low mold production efficiency , It is necessary to design a special thread removal mechanism, ejection mechanism and mold structure to complete the automatic injection molding production of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compound reversible bottle cap injection mold, which is reasonable in design, compact in structure, stable in operation, safe and reliable, and convenient to use; in...
