Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to an injection mold for a light guide strip for an automobile. Background Art

[0002] Light guide strips are actually optical fibers. Atmosphere light optical fibers are divided into two types based on their temperature resistance. One is the conventional type, which is mostly used for indoor and furniture and home appliance lighting decoration. The other is the heat-resistant type, which can be used for outdoor, automotive, yacht and other lighting. During the elongation of automotive light guide strips, corresponding molding and processing molds are required for their processing.

[0003] An injection mold is a mold used in the injection molding process. It usually consists of a mold core and a mold cavity. Plastic particles are heated to melt, and then the molten plastic is injected into the mold under high pressure. After cooling, it forms the desired product shape. Injection molds are widely used in the manufacture of plastic products, such as daily necessities, electronic product housings, and automotive parts.

[0004] In the injection molds currently used to produce automotive light guide strips, injection material residues are easily generated inside the mold after injection molding, and just after injection molding, the temperature inside the mold and the residual injection material is high, making it inconvenient for the staff to clean it immediately. However, after a period of time, the injection material will solidify, which makes it difficult for the staff to clean it up later and will also affect the next use. Utility Model Content
