The usual joining, to achieve the function of the mechanical connection in the part to make a product with a buckle or a barb, it is necessary to provide the product to make the product, the mold towel skew pin to form the buckle or pour Hook, and with the thimble to release the finished product of this product. Furthermore, the concave and convex shape of the plastic product is mainly divided into two types: the outer side surface unevenness and the inner side surface unevenness. 'The concave and convex shape or the side hole of the inner side surface can be formed by using the oblique pin in the mold, and the oblique pin and the thimble will be replenished when the mold is opened. The finished product moves together and leaves the mold cavity. In the prior art, the oblique pin adopts a square pattern, and the push plate is pushed to move up and down, and the oblique pin slides in a sliding manner in the oblique pin hole of the mold core to slide each other. Since the oblique pin and the oblique pin hole are closely attached to each other. When the pin is moved up and down in a plane friction manner, the force working surface is easy to be ground, and it is not easy to bite and jam after being heated, and the working face is not inclined. The pin holes are in contact with the whole surface and are closely attached. When the heat is expanded, it is easy to cause the injury bulge in the process of sliding each other, thereby causing the seizure to be stuck, so that the oblique pin is often pulled off. Therefore, the above problem is the purpose of the present invention. 099138697 Form No. A0101 Page 4 of 24 0992067448-0 201219191 [Summary Content] [0003]
