Description

Technical Field

[0001] This utility model relates to the field of cooling plastic film technology, specifically to a three-dimensional cooling plastic film structure. Background Technology

[0002] With the rapid development of new energy vehicles, the corresponding internal electrical components are also being upgraded. To meet the demands of high current, connector sheaths must possess high-temperature resistance and flame-retardant properties, such as... Figure 1 The image shows a connector sheath made of a new material. It is a multi-cavity mold, and the molding temperature is between 280 and 340 degrees Celsius. The existing technology uses a single-layer closed-loop cooling water circuit module, but this cooling method cannot achieve timely cooling, resulting in an excessively long product molding cycle and unstable product quality. Utility Model Content

[0003] To address the shortcomings of existing single-layer closed-loop cooling water circuit modules, which cannot cool products in a timely manner, resulting in excessively long product molding cycles and unstable product quality, this utility model provides a three-dimensional cooling plastic film structure that can cool products in a timely manner, resulting in shorter product molding cycles and more stable product quality.

[0004] This utility model provides the following technical solution:

[0005] It includes a three-dimensional moving mold, with model assembly ports symmetrically arranged on the end faces of the three-dimensional moving mold. Below the model assembly ports, a matching fixed mold base is installed in the three-dimensional moving mold. The feature is that a circumferentially arranged through pipe is provided around the outer wall of the fixed mold base. The circumferential through pipe is U-shaped and connected to each other in sequence. Near the inner wall of one side of the three-dimensional moving mold, the circumferential through pipe of the fixed mold base is connected to each other through a connecting pipe. Near the inner wall of the other side, there is an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe are connected to the adjacent circumferential through pipe from bottom to top, forming a three-dimensional circulation loop.

[0006] Its further features are:

[0007] The three-dimensional moving mold has a model flow channel in the middle. The model flow channel is T-shaped and has through holes at both ends of its transverse flow channel. The protruding part of the lower part of the fixed mold base is connected to the through hole of the model flow channel through a connecting pipe.

[0008] The three-dimensional moving model is installed on the pad, the pad has a spatial water passage inside, and the end face of the pad has a connecting hole corresponding to the water inlet pipe and the water outlet pipe;

[0009] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0010] By setting up a surrounding pipe around the fixed mold base, and connecting the connecting pipe, water inlet pipe and water outlet pipe through the surrounding pipe to form a three-dimensional circulation loop, the connector sheath installed in the fixed mold base can be cooled evenly in a timely manner. Compared with a single-layer closed cooling loop, the three-dimensional circulation loop has a faster and more uniform cooling speed, reduces the molding time of the product, and makes the product quality more stable.

[0011] Model runners are runners used in material injection molds, which allow material to be filled into the fixed mold base more evenly. Attached Figure Description
