Cooling water channel and ejection device for mold ejection device

Abstract

The invention relates to the mould field, in particular to a cooling water channel used for a mould lift-out device and the lift-out device capable of shortening the product cooling time, reducing cost, and improving product quality. The cooling water channel used for the mould liftout device comprises a water channel. The water channel comprises a first water channel, a second water channel and a third water channel. A cooling water machine is connected with a water inlet of the first water channel. A water outlet of the first water channel is connected with a water inlet of the second water channel. A water outlet of the second water channel is connected with a water inlet of the third water channel. A water outlet of the third water channel is connected with a water inlet of the cooling water machine. According to the design of the cooling water channel used for the mould lift-out device and the lift-out device, two flow courses are adopted. The cooling flow course is used for cooling products, and the auxiliary flow course is used for exchanging heat with the cooling flow course so that the constant temperature of cooling water in the cooling flow course can be well guaranteed; the product cooling effect is good; cooling time is shortened, and then enterprise cost is reduced.

Description

technical field [0001] The invention relates to the field of molds, in particular to a cooling water channel for a mold ejector device and an ejector device. Background technique [0002] As we all know, in mold production, in order to ensure the beauty of the mold product, some auxiliary runners will be designed to reduce the ejector pin mark on the mold product, and used to eject the product when the mold is opened, but usually when the auxiliary runner ejects the product, The cooling time of the product is long, the product is easily deformed, and the amount of plastic is increased, which greatly wastes the plastic, increases the cost of the enterprise, and affects the quality of the product. [0003] In view of the above problems, enterprises should really design a cooling water circuit and ejector device that can not only reduce product cooling time, but also reduce plastic waste, ensure product quality standards, and reduce enterprise costs. SUMMARY OF THE INVENTION ...
