Background technique

Cars have become one of the important means of transportation for people. On the premise of not changing the function and structure of the car itself, the appearance of the car can be changed by adding or modifying exterior parts, so as to make the car more beautiful and fashionable to meet people's aesthetics. and individual needs. Car decorative strips are one of the exterior decorative parts of automobiles. Car decorative strips increase the beauty of the side of the car body. They are highly consistent with the curvature of the car body. They are durable and not deformed. At the same time, they provide effective protection for the body paint that is easy to bump when the door is opened and closed.

Injection mold is a tool for producing plastic products. It injects heated and melted material into the mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. Obviously, the injection mold is also one of the important equipment for the manufacture of automobile decorative strips. Due to the thin thickness and complex shape of the automobile decorative strips, it is very difficult for the injection mold to eject the product, and the phenomenon of ejecting the product often occurs, which greatly reduces the cost of the finished product. yield rate.

It is further defined that each ejection mechanism described in the above technical solution includes a ejector rod and an ejector block fixedly installed on the top of the ejector rod; each of the recovery mechanisms includes a spring guide post and a spring guide post sleeved Return spring.

It is further defined that a plurality of push plate guide posts for guiding the push plate are installed on the bottom plate described in the above technical solution.

It is further defined that a plurality of sleeve-type limit screws for limiting the displacement distance of the push plate are installed on the bottom needle plate described in the above technical solution.

The beneficial effects of the utility model are: a kind of injection mold used for manufacturing automobile decorative strips of the utility model, a plurality of ejection mechanisms for ejecting the die are jointly installed on the face needle plate and the bottom needle plate, so that During the production process of injection mold, the ejection action is smoother, and the product is evenly stressed, and it is not easy to be broken, which greatly improves the yield of the product; at the same time, by installing multiple pins on the needle plate for restoring the fixed plate of the die The recovery mechanism, multiple recovery mechanisms for recovering the punch are also installed on the base plate, which makes the mold clamping process faster in the production process of the injection mold and greatly improves the injection efficiency of the mold.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, an injection mold for manufacturing automobile decorative strips has a panel 1, a die fixing plate 2, a die 3, a punch 4, a punch fixing plate 5, a push die set in sequence from top to bottom. Plate 6, face needle plate 7, bottom needle plate 8 and bottom plate 9; a wear-resistant plate 10 is arranged between the contact side wall of the die 3 and the die fixing plate 2, and a wear plate 10 is arranged between the side wall of the die 3 and the vertical surface The formed angle is 2°～4°; the face needle plate 7 and the bottom needle plate 8 are jointly installed with a plurality of ejection mechanisms for ejecting the die 3, and the face needle plate 7 is equipped with a plurality of ejection mechanisms for restoring The recovery mechanism of the die fixing plate 2 is also equipped with a plurality of recovery mechanisms for recovering the punch 4 on the base plate 9; the upper surface of the panel 1 and the lower surface of the base plate 9 are all provided with a heat insulating plate 11.

Wherein, each ejector mechanism includes a push rod 12 and a ejector block 13 fixedly installed on the top of the push rod 12; each return mechanism includes a spring guide post 14 and a return needle spring 15 sleeved on the spring guide post 14, wherein The length of the return needle spring 15 is 250mm, the ejection height is 80mm, the pre-compression length is 15mm, and the compression ratio is 38%. A plurality of push pedal guide posts 16 for guiding the push pedal 6 are installed on the base plate 9 .
