Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a rapid cooling molding device for injection molding production. Background Technology

[0002] In injection molding production, cooling time typically accounts for more than 70% of the entire molding cycle, directly affecting production efficiency, energy consumption, and product quality. Rapid cooling molding equipment can shorten cooling time, improve product uniformity, and reduce overall costs.

[0003] For example, the utility model patent disclosed in publication number CN221736992U discloses a rapid cooling injection molding device, including a device body. A cooling plate is fixedly connected to the inner wall of the device body, and an injection mold is arranged above the cooling plate. Cooling channels are formed inside the cooling plate. This device uses the cooling plate to place the injection mold. A pump draws water from inside the device body and, with the help of a water supply pipe, delivers the water to the cooling channels for circulation. The contact between the cooling plate and the injection mold accelerates cooling. A chiller, in conjunction with a temperature sensor, regulates the temperature of the cooling water inside the device body to maintain a low temperature, ensuring cooling efficiency. A fan dissipates heat from the side of the injection mold, further ensuring the cooling effect.

[0004] Although the above-mentioned equipment can cool the injection mold, its cooling efficiency is still insufficient, which reduces the production efficiency of the injection mold in cooling the injection parts. Therefore, there is an urgent need for a rapid cooling molding device for injection molding to solve the above problems. Utility Model Content

[0012] Preferably, the upper injection mold is fixedly engaged with the upper surface of the lower injection mold by means of the positioning guide shaft and the positioning slide groove. The sliding limit of the positioning guide shaft and the positioning slide groove can effectively improve the accuracy and stability of the subsequent positioning of the upper injection mold to the upper part of the lower injection mold.

[0013] Preferably, the lower injection mold is hollow inside, and the flow pump is connected to the lower injection mold, which can effectively improve the efficiency of the flow pump in circulating and guiding the coolant inside the lower injection mold.

[0014] Preferably, the heat-conducting fan is directly opposite the heat exchange duct, and the pusher plate is sealed and slidably engaged inside the lower injection mold. The pusher plate can quickly eject the injection molded part that has been injected into the lower injection mold, thereby improving the efficiency of subsequent material unloading.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a cooling device and heat-conducting fans, allows two sets of guide pumps to circulate the coolant into the lower injection mold through heat exchange pipes during the circulating cooling of the injection molded parts. This rapidly removes heat from the injection molded parts inside the lower injection mold, effectively improving the cooling efficiency of the injection molded parts. Furthermore, multiple sets of heat-conducting fans provide air cooling to the circulating heat exchange pipes, further improving the heat dissipation efficiency of the coolant. Simultaneously, the heat-conducting fans can also directly dissipate heat from the lower injection mold.
