Abstract

The invention relates to a blowing mould. The blowing mould comprises a mould body and is characterized in that the mould body is composed of a first mould body and a second mould body; each of the middle of the first mould body and the middle of the second mould body is provided with a mould cavity; at least three ejector rods are fixed to the periphery of the mould cavity of the second mould body; holes matched with the ejector rods of the second mould body are formed in the periphery of the first mould body; a blow molding hole is formed in one sides of the mould cavities; and a damping device is arranged at the bottom end of the second mould body. The blowing mould has the advantages that the structure is simple; use is convenient; the manufacturing cost is low; a damping gasket has the good damping effect; the use effect is good; performance is stable; and the mould meets the requirement of a small enterprise.

Description

technical field [0001] The invention relates to a mold, in particular to a blow mold. Background technique [0002] Blow molding is the third largest plastic processing technology in the world. It is widely used to produce hollow thin-walled objects made of thermoplastics. In the past 20 years, blow molding has experienced rapid development and has been used in automobiles, sports and leisure, and electronic products. , office supplies, automation equipment, packaging and other fields. In general, there are two main types of blow molding: extrusion blow molding and stretch blow molding. However, the existing injection molds have complex structures and high investment costs, which are not suitable for the needs of small enterprises. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0004] The object of the present invention is to provide a blow mold. [0005] The technical scheme adopted in the pr...
