Description

Technical Field

[0001] This utility model relates to precision manufacturing technology, and in particular to injection molding, specifically, an injection cooling device. Background Technology

[0002] In the field of injection molding technology, water cooling is a conventional cooling method. However, the current water cooling method involves setting water cooling pipes on the upper and lower mold bases, and the water cooling pipes work together to cool the outer periphery of the upper and lower mold cavities.

[0003] However, the current water cooling system is designed in the opposite way, failing to cool the interior of the upper and lower molds that form the mold cavity, resulting in low cooling efficiency.

[0004] Therefore, it is necessary to provide an injection molding cooling device. Utility Model Content

[0005] The purpose of this invention is to provide an injection molding cooling device.

[0006] The technical solution is as follows:

[0007] An injection molding cooling device includes a middle cooling structure disposed on an upper mold, the middle cooling structure including a cooling water inlet disposed on a lower mold, and a middle water cooling pipe module having a water cooling pipe passing through the upper mold and the lower mold.

[0008] The central water-cooling pipe module includes a set of central water-cooling main holes set at the corners of the molding cavity, and several central water-cooling secondary holes set at the corresponding central water-cooling main holes. The central water-cooling main holes and central water-cooling secondary holes are combined to form a central high-efficiency cooling support structure that passes through the upper and lower molds.

[0009] Furthermore, the number of secondary water-cooling holes in the middle body is 3-5.

[0010] Furthermore, several secondary water-cooling holes in the middle body are arranged between a set of main water-cooling holes in the middle body.

[0011] Furthermore, the edges of the main water-cooling hole and the secondary water-cooling hole in the middle body are both no less than 3-5 cm away from the forming mold cavity.

[0012] Furthermore, the number of cooling water inlets is 3-5.

[0013] Furthermore, the diameter of the main water-cooling orifice in the middle body is 2-4 times that of the secondary water-cooling orifice in the middle body.

[0014] Furthermore, the diameter of the secondary water-cooling orifice in the middle body is 1.3-3 times that of the cooling water inlet.

[0015] Compared with existing technologies, this utility model can effectively improve the cooling effect after injection molding and ensure production efficiency through a central high-efficiency cooling support structure. Attached Figure Description
