Description

Technical Field

[0001] The utility model relates to the technical field of plastic part injection molds. More specifically, the utility model relates to an external circulation water cooling structure for a plastic part injection mold. Background Art

[0002] A plastic part injection mold is a tool for producing plastic products. The injection mold consists of a moving mold and a fixed mold. After the injection molding is completed, the injection mold needs to be cooled down, so a water cooling structure is used.

[0003] For example, a circulating water cooling structure of an injection mold disclosed in CN217395632U has the following technical solution key points: It includes an operating table. At the center of the top of the operating table, an injection mold is installed. At the side of the top of the operating table, side plates are fixed. A hollow disc is fixed between the side plates. A magnetic ring is magnetically connected to the bottom of the hollow disc. A handle is fixed to the outer wall of the magnetic ring. A corrugated pipe is fixed to the bottom of the magnetic ring. The bottom of the corrugated pipe is fixedly connected to the top of the operating table. A water tank is installed at the bottom of the operating table. A water collecting tank is arranged at the top of the operating table. A water channel is opened at the bottom of the water collecting tank. A water pipe penetrates through one side of the water tank. The end of the water pipe is connected to the top of the hollow disc. A water pump is installed on the water pipe. The water pump is installed on the outer wall of the water tank. A first water spray nozzle is arranged at the bottom side of the hollow disc. A second water spray nozzle is arranged at the center of the bottom of the hollow disc. It mainly starts the water pump. The water pump can pump the cooling water inside the water tank to the hollow disc through the water pipe, and then spray it out through the first water spray nozzle and the second water spray nozzle, so as to cool the periphery and the top of the injection mold at the same time, thereby improving the cooling efficiency. And the cooling water can be recycled back to the inside of the water tank through the water collecting tank and the water channel. At the same time, by pulling down the handle, the magnetic ring can be separated from the hollow disc, so that the top of the corrugated pipe can move downward, and then the injection mold can be exposed, which is convenient for taking out the mold after the injection mold is cooled.

[0004] The above external circulation water cooling structure for a plastic part injection mold still has certain deficiencies: Since the external circulation water cooling structure does not have a gear lubrication function, once the gears inside the water pump rust, it will affect the operation of the water pump at this time, and then reduce the water cooling effect of the device.

[0009] Wherein, a surface of the limiting plate is adapted to an inside of the chute, a side wall of the limiting plate is connected with one end of the hydraulic telescopic rod, and a depth of the chute is less than a length of the water inlet pipe.

[0010] Wherein, the lubricating component includes a first hydraulic lifting rod, a first stabilizing plate and a storage cylinder, a top end of the first hydraulic lifting rod is fixedly connected with the first stabilizing plate, and a bottom end of the first hydraulic lifting rod is connected with a side of the upper surface of the water pump.

[0014] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0015] 1. In the above solution, the external circulation water cooling structure is provided with a hydraulic telescopic rod, a sliding groove and a limiting plate. When the filter screen arranged inside the water inlet pipe is blocked, the hydraulic telescopic rod is started at this time, so that it drives the limiting plate to move upward from the bottom. Since the surface of the filter screen is connected to the side wall of the limiting plate, the movement of the limiting plate can drive the filter screen to move until the filter screen is removed from the water inlet pipe, which is convenient for the staff to clean the blocked filter screen. Also, because the hydraulic telescopic rod has the function of automatic telescoping, it is convenient to take and place the filter screen, thus saving the time required for work.
