In the mold design, automobile molds have always been considered difficult molds. Sometimes I feel unable to get a product. Today I will share with you a set of classic automobile lamp mold structure. I hope you will encounter this kind of mold in the future. The product, in terms of design, can give 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, and dot glue. The small nozzle turns the large nozzle into the glue, etc. This set of auto lamp mold uses hot runner to cold runner to dive into the glue, as shown in the following figure:
2. From the slope of the product, it can be seen that there is a horizontal slider in front of the product. There is an oblique slider behind the product, two tunnel sliders on the right side of the product, and an oblique top on the back mold. The analysis results are shown in the figure below:
3. There is a horizontal sliding block in front of the product. According to the common sliding block design method, the design of this small sliding block should pay attention to: the strength and craftsmanship of the sliding block, because the row inserts need heat treatment, in order to reduce the stress concentration, the surrounding of the row position A round corner transition is required, as shown in the following figure:
4. There is an oblique undercut behind the product and two tunnel sliders on the right side. In order to reduce the length of the oblique guide post, the oblique guide post is fixed with a pressure block to facilitate processing , The tunnel slider is fixed on the row seat by T-shaped groove, which is convenient for line cutting, as shown in the following figure:
5. There is a slanted top on the back mold, and there is a needle under the slanted top. When designing this kind of slanted top, pay attention to that the slanted top cannot interfere with the inserts. The slanted top is designed according to common standards, as shown in the following figure:
