An injection mold with an inner barb structure for easy disassembly

Abstract

The invention discloses a plastic injection mold convenient to demount and provided with a barb structure. The plastic injection mold comprises a base. Support rods are fixedly connected to the upper surface of the base, and a lower mold is fixedly connected between the two support rods. A casing pipe is connected to each support rod in a sleeving manner, and an upper mold is fixedly connected between the two casing pipes. A cantilever is fixedly connected to the upper surface of the base. A bearing is connected to the lower surface of the cantilever in a clamped manner. A threaded rod is connected into the bearing in an inserted manner. According to the plastic injection mold, after plastic injection molding is completed through the mold, a U-shaped clamp is pulled out of limiting grooves, and thus fixation of a support and a limiting block is eliminated; subsequently, the limiting block is pulled out, and thus the support can move transversely; the support is moved transversely, so that the barb mold is separated from a workpiece; and then, the support is vertically drawn out, the barb mold can also be taken out, and thus the problem that when the workpiece is taken out, stress is generated between a barb structure of the workpiece and the mold, so that a barb of the workpiece is pulled to be broken is avoided.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with an inner barb structure which is easy to disassemble. Background technique [0002] Molds, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting, forging, smelting and stamping to obtain the required products, in short, molds are tools used to make shaped objects , this kind of tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material. It is known as the "mother of industry". The injection mold is a batch A processing method used in the production of certain parts with complex shapes, mainly used in the industrial field. The process of injection molding is to inject the heated and melted material into the mold cavity by high pressure, and...
