Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a product ejection structure used in injection molds. Background Art

[0002] This product is a cover for the high-mounted brake light. The high-mounted brake light is typically located in the center of the rear of a vehicle. It works in conjunction with other lighting devices, such as brake lights, width marker lights, and reverse lights, to provide drivers with comprehensive driving safety. At night or in inclement weather, the high brightness and visibility of the high-mounted brake light help other vehicles more easily detect changes in the vehicle ahead, thereby reducing the risk of accidents.

[0003] After the high-mounted brake light is installed on the vehicle, it needs to be sealed. If the sealing effect is not good, it is easy to cause the LED circuit inside to short-circuit, causing driving risks. The quality of the sealing effect depends on the product quality of the cover.

[0004] The high-mounted brake light cover measures 210*200*44mm (note: 44 is the mold height in the demolding direction). Made of ABS+TPE, it utilizes a two-shot mold structure and two-shot injection molding. The soft rubber primarily serves as a seal. The front and rear mold cores serve as inserts, and the mold is a two-outlet (1+1) configuration. A needle valve hot runner system is used on the HT530-ton injection molding machine. The Green column dimensions are 1170*700*(400-910)mm (400-910 is the mold thickness).

[0005] Currently, similar structural molds on the market use cylinders to eject products, but the cylinders need to be fixed inside the mold. The problem that is likely to occur is that the mold temperature is high and the cylinder is prone to failure. Utility Model Content
