Problems solved by technology

[0002] The cooling water channel of the mold for deep cup-shaped products has the disadvantage that it cannot reach the depth during the cooling process, which makes the injection temperature of the rear mold insert too high, which will easily lead to deformation of the rear mold insert for a long time, and then make the mold Short working life increases injection molding costs

Abstract

The invention provides a spiral-type cooling water channel mold structure which cools rear mold inserts deeply and uniformly, and guarantees that the rear mold inserts are not deformed, further the service life of a mold is long, and the injection molding cost is reduced. The spiral-type cooling water channel mold structure comprises a front mold, a rear mold, a front mold insert and a rear mold insert which define a cavity; the cavity is internally provided with a product. The spiral-type cooling water channel mold structure is characterized in that the center of the rear mold insert is provided with a central cylindrical cavity body; the rear mold is supported to a plate B; a water intake cavity is formed in one side of the plate B, and a water drainage cavity is formed in the other side of the plate B; the water intake cavity comprises a horizontal end and a vertical end; the bottom of the vertical end is communicated with the inner side of the horizontal side; a spiral water conveying sleeve is sleeved in the central cylindrical cavity body.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a spiral cooling waterway mold structure. Background technique [0002] The cooling water channel of the mold for deep cup-shaped products has the disadvantage that it cannot reach the depth during the cooling process, which makes the injection temperature of the rear mold insert too high, which will easily lead to deformation of the rear mold insert for a long time, and then make the mold The working life is short, which increases the cost of injection molding. Contents of the invention [0003] The invention provides a spiral cooling waterway mold structure, which enables the cooling of the rear mold insert to reach a deep and uniform cooling, ensures that the rear mold insert does not deform, and thus makes the working life of the mold long and reduces the cost of injection molding . [0004] A spira...
