Cooling water circulating device for PE wood-plastic composite mold

Abstract

The invention discloses a cooling water circulating device for a PE wood-plastic composite mold. The cooling water circulating device for the PE wood-plastic composite mold comprises a support plate and a core rod body, wherein one end of the core rod body is connected to the support plate, and the other end of the core rod body comprises four core rods; four sets of first cooling pipe holes are formed in the upper side of the support plate; four sets of second cooling pipe holes are formed in the lower side of the support plate; a third cooling pipe hole and a fourth cooling pipe hole are formed in the end surface of one end of each core rod; cooling pipe threads are arranged at one end of each third cooling pipe hole and one end of each fourth cooling pipe hole respectively, wherein a cooling water tank is arranged at the other ends of the cooling pipe threads, and the two cooling pipe threads are assembled together in the cooling water tank; a first cooling pipe inclined hole is formed in the upper side of one end of each core rod; and a second cooling pipe inclined hole is formed in the lower side of one end of each core rod. According to the cooling water circulating device for the PE wood-plastic composite mold, the failure rate of the mold is decreased, the maintenance cost of the mold is reduced, and use is convenient and reliable.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of mold manufacturing, in particular to a PE wood-plastic mold cooling water circulation device. [0003] 【Background technique】 [0004] At present, in the cooling water circulation device of PE wood-plastic mold, the water pipe groove is often processed by milling machine on the support plate, and after the cooling water pipe is installed in the water pipe groove, the water pipe groove is sealed with brass or aluminum. Due to the fact that material leakage often occurs inside the mold in actual production, the fluid material with a certain pressure will squeeze the bracket plate, causing the brass or aluminum sealed water pipe groove to be concave, and further squeeze the cooling water pipe in the water pipe groove , causing the cooling water pipe to be blocked and the entire production line to stop. [0005] 【Content of invention】 [0006] In view of this, in order to overcome the deficiencies o...
