Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to an injection stamping mold for producing parts with holes. Background Art

[0002] A mold is a tool used in industrial production to make formed articles. By methods such as injection molding, blow molding, extrusion molding, die casting, or forging, materials are formed into the required products. The mold is composed of various parts. Different molds are composed of different parts and have specific contour or inner cavity shapes, through which the blank can be formed or separated.

[0003] Application No.: CN201911375778.X discloses an injection stamping mold for producing parts with holes, including a machine body. An injection cavity is provided in the machine body. A moving cavity is provided on the left side of the injection cavity. A retraction cavity is communicated between the moving cavity and the injection cavity. An extension cavity is provided on the right side wall of the moving cavity. The inductor opens the injection motor through the induction wire, and then controls the two threaded plates to approach each other, so as to convey the raw materials in the storage cavity outward through the conveying cavity to the injection space formed between the moving body and the left side wall of the injection cavity to realize injection molding. When the molded part falls off, the uppermost push rod is pushed in a telescopic manner by sliding, so that the telescopic distance is longer than that of other rods, facilitating the uppermost part of the part to fall off first.

[0004] When the existing injection stamping mold is used for injection molding of parts with holes, there is a stamping structure at the mold to drive the stamping rod into the mold to punch holes in the parts with holes. However, when the parts with holes are being punched, they are fixed between the molds, and the punching pieces on the surface of the parts after punching are not easy to fall off after the punching rod retracts. As a result, it is often necessary to laboriously clean the punching pieces out of the hole cavity at the punching position of the parts, causing the production of parts with holes to be cumbersome. For this reason, we propose an injection stamping mold for producing parts with holes. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an injection stamping mold for producing parts with holes. A stamping mechanism is arranged at the injection mold body near the injection port, so that the mold not only has an injection function but also integrates a stamping mechanism, can directly punch holes in the parts after injection molding, realizes the function of multi-purpose in one machine. At the same time, the punching materials generated after punching can be taken away and ejected by the punching pipe of the stamping mechanism, facilitating the rapid and convenient production of parts with holes at the mold of the utility model, and effectively solving the problems in the background art.

[0036] It should be noted that the present utility model is an injection molding and stamping die for producing parts with holes. A stamping mechanism 3 is arranged at the injection molding die body 1 near the injection port 2. After the punching hole 4 of the stamping mechanism 3 is matched with the connecting rib 5, the guide post 6 and the punching pipe 8 and arranged at the top of the injection molding die body 1, the connecting pipe plate 10 at the top of the punching pipe 8 is locked at the head locking plate 11 below the hydraulic cylinder 12 through bolts. Then, a long bolt passes through the mounting frame of the injection molding equipment, so that the long bolt passes through the spacer pipe 15 and is screwed outside the die mounting hole of the injection molding die body 1.
