AI Technical Summary
The existing injection mold exhaust system is incomplete, resulting in welded wire marks and floating fiber lines on the surface of the product, affecting the appearance of the product and subsequent dispensing process, resulting in poor product and low production efficiency.
A mold core assembly is designed, including a mold core and a mold core insert installed on the mold core. The upper surface of the mold core is equipped with an installation groove. The insert is installed in the groove and is equipped with an exhaust groove and an air guide groove. The depth of the exhaust groove is 0.015~0.02mm. The air guide groove is in communication with the exhaust groove to ensure that the gas can be discharged smoothly.
Through an effective exhaust system, the gas trapping problem of injection molds is solved, the product yield rate is greatly improved, the floating height of the inlay line is reduced, and the quality of subsequent dispensing processes is improved.
