These molds are usually used to produce plastic parts that require thick walls, complex structures or large sizes, such as automotive parts, home appliance housings, industrial containers, etc. Compared with ordinary injection molds, deep cavity injection molds have some special considerations and challenges in design and manufacturing. The cavity and core design of deep cavity injection molds are crucial in plastic injection molding, especially when used to manufacture complex shapes or large-sized plastic products.

The injection mold cooling mechanism can quickly cool the injection mold internally by injecting cooling water into the water inlet, without the need for the staff to wait for natural cooling; and then the fan is used for secondary cooling and removal of the remaining cooling water of the former, which is highly practical.

[0004] During the conception process, the applicant searched a large number of patent documents on the patent network. For example, Chinese patent publication number CN215040015 U discloses "an injection mold cooling mechanism". During use, the condensation water pipe is long, resulting in uneven temperature at the front and back of the condensation water pipe, which leads to uneven cooling temperature of the rear mold, thus affecting the cooling effect and demolding efficiency. Therefore, a deep cavity injection mold cavity core cooling mechanism is proposed to solve the above-mentioned problems. Utility Model Content

To achieve the above purpose, the utility model is implemented through the following technical scheme: a deep cavity injection mold cavity core cooling mechanism, including an operating table, a front mold is slidably mounted on the operating table, a rear mold is mounted on the operating table, a cooling device is arranged on the operating table, the cooling device includes a hydraulic cylinder, the hydraulic cylinder is mounted on the operating table, the output end of the hydraulic cylinder is connected to a condenser, and a plurality of condensing water pipes are mounted on the condenser.

[0006] Preferably, a plurality of cooling grooves are provided on the rear mold, and the plurality of cooling grooves are respectively located on the movement tracks of the plurality of condensation water pipes.

[0007] Preferably, an insect-proof device is provided on the rear mold, and the insect-proof device includes two connecting rods, the two connecting rods are respectively hinged on both sides of the condenser, and the ends of the two connecting rods away from the condenser are respectively hinged to two sliding rods, and the two sliding rods are respectively connected to two mounting frames.

[0008] Preferably, the two mounting frames are both slidably mounted on a side of the rear mold close to the condenser, and two insect-proof nets are respectively mounted on the two mounting frames.

[0012] It can be seen from the above technical solutions that a deep cavity injection mold cavity core cooling mechanism provided in the embodiments of this specification has at least the following beneficial effects:

[0013] (1) The utility model provides a cooling device so that after entering multiple cooling tanks, the condensation water pipes absorb the temperature of the rear mold by contacting with the inside of the rear mold. Since the multiple condensation water pipes cool multiple parts of the rear mold at the same time, the movement distance of the condensation water in a single condensation water pipe is shorter, the overall cooling efficiency is higher, and the cooling effect of various parts of the rear mold is more uniform, thereby avoiding the situation where the front and rear temperatures of the condensation water pipes are uneven due to the long condensation water pipes, thereby causing uneven cooling temperature of the rear mold, affecting the cooling effect and demolding efficiency.

[0014] (2) The utility model provides an insect-proof device so that the two insect-proof nets can protect the cooling groove on the rear mold when the rear mold stops operating, thereby preventing some insects from entering the cooling groove and causing blockage of the cooling groove, thereby affecting subsequent use. In addition, the cleaning brush and the insect-proof net can be used in conjunction with each other to clean the surface of the insect-proof net during its movement, thereby keeping the net clean. The air-cooling device can be provided so that when the condenser is reset after completing the cooling operation, the fan rotates to cool the multiple condensing water pipes moving below it. Since the multiple condensing water pipes have a certain amount of heat on their surfaces when they just come out of the multiple cooling grooves, the multiple condensing water pipes can be cooled faster by the auxiliary cooling of the fan, thereby reducing the workload of the condenser and achieving the effect of energy saving.
