Description

Cooling water channel structure for plastic bottle molding and processing Technical Field The utility model relates to the technical field of plastic bottle processing dies, in particular to a cooling water channel structure for plastic bottle molding and processing. Background The plastic bottle is mainly made of polyethylene or polypropylene and other materials and is added with various organic solvents, polyester (PET), polyethylene (PE) and polypropylene (PP) are widely used as raw materials, and after the corresponding organic solvents are added, the plastic bottle is heated at high temperature and then is subjected to blow molding, extrusion blowing or injection molding through a plastic mold; In the blow molding process, plastic particles are hot-melted and poured into a mold to be subjected to blow molding, the mold has higher heat, cooling liquid is generally introduced into a cooling water channel of the mold to cool the mold and plastic products, but the upper temperature and the lower temperature of the cooling liquid in the cooling water channel are different, the temperature of the cooling liquid close to a cavity part is higher, and the temperature of the cooling liquid far away from the cavity part is lower, so that the cooling effect is reduced, and the waste of the cooling liquid is caused. Disclosure of utility model The utility model aims to provide a cooling water channel structure for plastic bottle molding processing, which solves the problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a plastic bottle shaping processing is with cooling water course structure, includes the mould body, the inside of mould body evenly is provided with a plurality of cooling channel, the side fixed mounting of mould body has the pipeline, fixedly communicate on the pipeline has a plurality of shells of intaking, every the shell of intaking all pegs graft in the inside of cooling channel; the cooling channel is divided into a first straight line section, an arc line section, a second straight line section and a rotating section, the first straight line section, the arc line section, the second straight line section and the rotating section are connected in an end-to-end mode and are sequentially distributed in the die body, an arc line opposite to the arc line section coincides with the circle center of a side arc line of a die cavity of the die body, a bulge is arranged in the rotating section, and the bulge is fixedly mounted on the inner wall of the rotating section in a spiral mode.
