Description

Technical Field

[0001] The utility model relates to the technical field of lampshade processing, in particular to an LED lampshade injection mold. Background Art

[0002] As the use of LED lamps becomes more and more widespread, the production of lampshades to protect LED lamps is also gradually increasing. Injection molding machines are the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds. Injection molding is usually required when manufacturing LED lampshades.

[0003] For example, the LED lampshade injection mold disclosed in publication number CN219076374U, the device cools down the heat-conducting molding block by contacting the heat dissipation fin plate with the heat-conducting molding block and turning on the fan, thereby solving the problem that the slow heat dissipation of the injection mold during molding will affect the speed of the mold in manufacturing injection molded parts.

[0004] However, the above-mentioned discharge structure can only speed up the molding of the mold by dissipating heat at the bottom of the workpiece when in use. However, since the processing machine is in contact with the inner wall of the fixed mold, there will be a certain viscosity, which leads to poor efficiency in subsequent demolding. In view of this, we propose an LED lampshade injection mold. Utility Model Content
