Description

Mould with annular cooling water path

Technical Field

The utility model relates to a die, in particular to a die with an annular cooling water channel.

Background

The water path of the mold is an important part in the mold, is a blind hole or a through hole machined by using machining equipment in an injection mold frame, a mold core, an insert and the like, and is used for cooling the mold by cooling a certain medium in a circulating way in the mold, wherein common cooling mediums are as follows: oil, water vapor, water, and the like.

At present, a waterway of a die is generally a linear blind hole or a linear through hole, however, for non-planar products with cambered surfaces, cylindrical surfaces, spherical surfaces and the like, uniform cooling is difficult to realize because the distances between each part of the waterway and the products are different. When the product is cooled after injection molding, the product is easy to cause shrinkage, rugged and unstable in size, and the quality requirement of the product is not met.

Further, a plurality of fitting holes are provided around the insert hole on the bottom surface of the fitting positioning groove.

Further, a plurality of dowel pins are provided on the flange of the dowel end cap.

The cooling medium flows into the template water inlet arranged on the side face of the template, reaches the annular water channel inlet and outlet through the linear water channel, flows through the annular water channel to cool the product in the cavity, and flows out of the template from the template water outlet through the linear water channel.

Further, the insert and the insert hole are two.

Further, the number of the annular waterways is three, and the number of the corresponding annular waterways is three.

The utility model improves the existing waterway, and the improved annular cooling waterway of the die not only achieves the uniformity of the cooling temperature of the die, but also achieves the injection molding product with high quality requirement.

The conception, specific structure, and technical effects of the present utility model will be further described with reference to the accompanying drawings to fully understand the objects, features, and effects of the present utility model.

Detailed Description

The following description of the preferred embodiments of the present utility model refers to the accompanying drawings, which make the technical contents thereof more clear and easy to understand. The present utility model may be embodied in many different forms of embodiments and the scope of the present utility model is not limited to only the embodiments described herein.

As shown in fig. 1 to 3, the mold with an annular cooling water path according to the present utility model includes a mold plate 1 and an insert 2 fittable into the mold plate 1. As shown in fig. 1, the die plate 1 is provided with an insert hole 11 for fitting the insert 2. This embodiment includes two insert holes 11, and in other embodiments, one or more insert holes 11 may be provided as desired. A plurality of groups of annular waterway inlets and outlets 5 are arranged on the side wall of the insert hole 11 at intervals from top to bottom. In this embodiment, three sets of annular waterway inlets and outlets 5 are provided, corresponding to the three annular waterways. An assembly positioning groove 13 is provided around the opening of the insert hole 11 on the upper surface of the die plate 1. A plurality of fitting holes 9 are provided around the insert hole 11 on the bottom surface of the fitting positioning groove 13.

As shown in fig. 2, the insert 2 includes a cylindrical body 13. One end of the cylindrical body 13 is a cavity 4, and the other end is a positioning end cover 12 which can be matched with the assembly positioning groove 13. A plurality of annular grooves 3 are provided on the side wall of the cylindrical body 13. A plurality of dowel pipes 12 are provided on the flange 12 of the dowel end cap 12.

As shown in fig. 3, when assembling, the cylindrical body 13 of the insert 2 is placed in the insert hole 11 of the die plate 1, the positioning pin tube 12 is inserted into the assembly hole 9, and the positioning end cap 12 is fitted in the assembly positioning groove 13.
