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

Secondary ejection mould for forced removal of inner screw teeth of beverage cover

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

3D mold structure of car knee airbag oblique jacking and pushing block secondary ejection

The 3D mold structure of the car knee airbag cover plate inclined jacking and the push block secondary ejection is slightly complicated, and a little care has been taken in the design. For example, an inclined jacking is added at the bottom of the push block, and a push block is added at the position where the slider is broken. Because the slope of the A side of this product is increased, Since the inclined jack needs to be forced into the air at the bottom of the pushing block, so that the pushing block and the inclined jack are easy to move during the forming process, we added a shovel foundation on the male die insert to avoid the displacement of the inclined jacking pushing block during the production process
