Efficient heat-dissipation type blow-moulding mould

Abstract

The invention relates to the technical field of plastic part producing and processing, in particular to an efficient heat-dissipation type blow-moulding mould. The efficient heat-dissipation type blow-moulding mould comprises an upper mould structure, a lower mould structure, cooling structures, guide post structures, guide sleeve structures, rotary structures and accelerating structures, whereincooling structures are arranged inside the upper mould structure and the lower mould structure; accelerating structures are rotatably connected inside the cooling structures; the accelerating structures are arranged, so that flow speed of water inside a mould base can be increased, and therefore, better heat-dissipating and cooling effects can be achieved inside the mould; the accelerating structures provide power through the rotary structures, and the rotary mechanisms work through extrusion of two moulds, i.e., flow speed of water inside the cooling structures is increased when the two moulds are closed, so that water flow speed can be increased while the mould works; and while the mould does not work, water flow speed is normal, so that the effect of saving water resources is achieved.

Description

technical field [0001] The invention relates to the technical field of production and processing of plastic parts, in particular to a high-efficiency heat dissipation blow mold. Background technique [0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used. The volume of the hollow container can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. According to the parison production method, blow molding can be divided into extrusion blow molding and i...

Problems solved by technology

[0003] However, the traditional blow mold is only simply provided with water inlet and water outlet during use, and the heat dissipation and cooling of the mold are relatively slow.
