Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine with a heat dissipation function. Background Art

[0002] An injection molding machine is a mechanical device used in the production of plastic products. It injects heated and molten plastic into a mold through an injection process, and forms the desired plastic product after cooling and solidification. The injection molding machine needs to perform a large amount of plastic heating and cooling operations during its operation. The plastic is heated to a molten state to facilitate injection molding, and the cooling is to allow the plastic to solidify quickly in the mold to maintain the desired shape.

[0003] After searching, the Chinese patent document announcement number is: CN217862681U. The utility model discloses an injection molding machine with a protective function, including an injection molding machine body, the front surface and the back surface of the injection molding machine body are welded with auxiliary support plates, the top of the auxiliary support plate is provided with a protective cover, the front surface and the back surface of the protective cover are fixedly inlaid with a cooling fan, and the bottom of the protective cover surface is welded with a positioning component. The utility model uses an auxiliary support plate, a cooling fan, a mounting seat, a torsion spring, a movable rod, a connecting plate, an arc-shaped card plate, a connecting sleeve, an arc-shaped card slot, a protective cover, a positioning seat, a limiting slot, an empty slot, a storage sleeve, a spring, a vertical block and a card plate to solve the problem that the existing injection molding machine has a general convenience for disassembly and assembly of the cover, increases the labor intensity of the staff, and has a long disassembly and assembly time, which affects the subsequent injection molding production. At the same time, it does not have the function of auxiliary heat dissipation, and the heat accumulates inside the cover to affect the life of the machine body, which reduces the practicality of the injection molding machine.

[0004] The above patent mentions in the beneficial effects that "at this time, under the anti-slip friction effect of the installation component and the anti-slip component, and under the limiting installation effect of the positioning component and the limiting component, the protective cover can be prevented from moving up at will and completely separating from the injection molding machine body, so that the protective cover can shield and protect the injection molding machine body. During actual use, the cooling fan can be controlled to work at a fixed time so that the hot air accumulated in the protective cover can be quickly discharged to achieve auxiliary heat dissipation." Although protection and heat dissipation are achieved, the mold needs to fall onto the filter plate after injection molding. However, when falling, the debris generated after injection molding will also fall onto the filter plate. Under long-term filtration, the filter plate will be blocked, which requires staff to clean it. This will not only increase the downtime, but also increase the labor intensity of the staff. For this reason, an injection molding machine with heat dissipation function is proposed to solve the above problems. Utility Model Content
