In the mold design, the car mold has always been a mold that everyone thinks is difficult, sometimes get a product and feel at a loss, today I will share with you a set of classic car lamp mold structure, I hope that in the future, you will encounter this kind of product, in terms of design can bring you a little inspiration:
1. Product glue feeding method: There are many ways to glue the product, including bottom glue, diving glue, direct gate, horn glue, point glue, fine water port to large water inlet glue, etc., this set of automobile lamp mold uses hot runner to directly enter the surface of the product, as shown in the following figure:
2. From the slope of the product, it can be seen that there are three horizontal undercuts in front of the product, a horizontal undercut in the rear of the product, an oblique undercut in the left direction of the product, and an oblique undercut in the right direction of the product, as shown in the following figure:
3. There are three small sliders on the front of the product, according to the ordinary slider design method, the design of this small slider should pay attention to: the strength and process of the slider, because the row inserts need heat treatment, in order to reduce the stress concentration, the surrounding of the row needs to be rounded transition, as shown in the following figure:
Fourth, there is a horizontal inverted buckle behind the product, the rubber area of the slider is large, in order to prevent the glue position from sticking to the slider, the thimble is designed on the slider, because the slider needs heat treatment, in order to reduce the stress concentration, the periphery of the row needs to be rounded transition, as shown in the following figure:
Fifth, there is an oblique direction of the right side of the product, the design of this structure should pay attention to: the slider of the rubber encapsulation mode and the limit mode, because the slider needs heat treatment, in order to reduce the stress concentration, the periphery of the row needs to be rounded transition, as shown in the following figure:
Sixth, there is an oblique direction of the left side of the product, the design of this structure should pay attention to: the slider of the rubber encapsulation mode and the limit mode, because the slider needs heat treatment, in order to reduce the stress concentration, the periphery of the row needs to be rounded transition, as shown in the following figure:
