Bottle blank mold cavity plate cooling system

Abstract

The invention provides a bottle blank mold cavity plate cooling system. The bottle blank mold cavity plate cooling system involves a plate body, wherein an upper cooling flow channel system and a lower cooling flow channel system which communicate with a mounting groove are sequentially arranged inside the plate body in the thickness direction of the plate body from top to bottom, and the upper cooling flow channel system and the lower cooling flow channel system are evenly divided into cooling flow channel left modules and cooling flow channel right modules which are independent of each otherin the width direction of the plate body; and a water outlet flow channel system and a water inlet flow channel system are sequentially arranged on one side of the plate body in the thickness direction of the plate body from top to bottom, cooling media are fed into the upper cooling flow channel left modules, the upper cooling flow channel right modules, the lower cooling flow channel left modules and the lower cooling flow channel right modules through the water inlet flow channel system correspondingly, flow along S-shaped paths correspondingly, and flow out through the water outlet flow channel system after synchronously cooling the left half portion of a bottle blank mold and the right half portion of the bottle blank mold. The technical problems that in the prior art, the two bottleblank mold parts in the same plate body are inconsistent in cooling effect and long in cooling time are solved.

Description

technical field [0001] The invention relates to the field of bottle blank mold cooling, in particular to a bottle blank mold cavity plate cooling system. Background technique [0002] The preform injection molding machine is mainly composed of an injection molding machine and a multi-cavity mold. It is mainly used to produce plastic preforms. The preforms that are injected are further blow-molded to obtain products such as plastic bottles or medical packs. After preform injection molding, the product in the preform mold needs to be cooled. [0003] The Chinese invention patent with the application number CN201910664856.1 discloses a preform mold cooling plate, which includes a plate body. The surface of the plate body is provided with an installation groove for installing the preform mold. An upper cooling channel system and a lower cooling channel system are arranged in sequence from top to bottom, and the upper cooling channel system and the lower cooling channel system a...

Problems solved by technology

[0004] However, in the actual use process, the applicant found the following technical problems: the above-mentioned cooling path divides each preform mold on the plate body into two parts along the length direction, and the cooling medium successively cools the two parts along the S-shaped path. The preform molds are cooled separately. Firstly, this will lead to inconsistent cooling effects of the two parts. Obviously, the cooling effect of the latter part is greatly reduced; secondly, the long flow path leads to a long overall cooling time.
