The drawing is a 3D and 2D drawing of the screw tooth products in the common beverage cover. The classic part of the drawing is that the screw tooth is forced off rather than twisted. There are ribs inside the cover, which cannot be forced off directly. The ribs need to be demoulded first and then the screw tooth is removed. This is a secondary ejection structure. I hope this drawing can provide some inspiration for peers to solve the problem of this kind of mold. Thank you

A mold is a tool that uses its specific shape to form products with a certain shape and size. Various moulds are widely used in various material processing industries. For example, sand molds or die-casting molds used for metal casting, forging molds used for metal pressure processing, cold pressing molds and other molds. The overall requirement for the mold is that it can produce public owned products that meet the use requirements in terms of dimensional accuracy, appearance, physical properties, etc. From the perspective of mold use, it requires high efficiency and simple automatic operation; From the perspective of mold manufacturing, it requires reasonable structure, easy manufacturing and low cost. Mold affects the quality of products

One automobile wire rack outlet connector product, made of ABS, one for one mold, three plate mold structure glue feeding mode, two heads of the product need row position core pulling, the row position on the roof needs to be designed with spring, row position needs to be designed with cooling, and the reset uses the original swing rod form
-
The mold drawing is a support plastic part, 1X1, which uses hot runner to feed glue. Because there is a deep bone position in the direction of the rear mold of the product, it is difficult to eject the stuck rear mold in order to place it. Now, the mold uses the secondary ejecting of the rear mold. The mold action: the parting surface is opened, the ejector rod is ejected. Under the action of the fastener, two groups of ejector plates go up at the same time to reach the set stroke (the fastener is opened), and the one-time ejecting does not move, The second ejection continues to eject the product. The drawing file has a clear structure, which can be used for reference

The failure of the nylon rubber stopper opener is often encountered in the plastic mold, which leads to the disorder and instability of the opening and closing sequence. For molds with strict requirements on mold opening sequence, mechanical shutters (mechanical locking, safe and reliable) must be used. They are often used in export molds. Many companies require that rubber plugs cannot be used. The mechanical shutter belongs to the secondary ejection type. The purpose of the mechanical shutter is different from that of the common secondary ejection type fastener. The common secondary ejection is that two groups of ejector plates go up at the same time, and the lower group continues to eject without moving the upper group. The mechanical shutter is that two groups go up at the same time, the upper group does not move, and the lower group continues to eject, thus
