Description

Injection mold of screw thread milk teacup Technical Field The utility model belongs to the technical field of injection molds, and relates to an injection mold of a threaded milk tea cup. Background The injection mold is a device for producing plastic products, which heats plastic raw materials to a molten state, and then injects the plastic raw materials into a forming cavity arranged in the mold, after the forming cavity is filled, the mold is rapidly cooled, the molten plastic raw materials are cooled and shaped, so that the required plastic products are formed, and the plastic products are produced by adopting the injection mold, thereby having the advantages of high precision, high efficiency and the like. Most of the cup bodies of the milk tea cups in the market are made of plastic raw materials, so that the cup bodies of the milk tea cups can be produced through injection molds. However, the milk tea cup injection mold in the technology can produce the milk tea cup with a single structure, the cup body is of a truncated cone structure, the cup mouth is provided with an outwards protruding annular edge for heat sealing a layer of plastic film to prevent beverage in the cup from spilling, but the milk tea cup can only be used for disposable use, is unfavorable for environmental protection, and cannot cover the cup mouth again after the milk tea cup is opened, so that the milk tea cup is unfavorable for carrying and preservation. Therefore, threads can be arranged at the cup mouth of the milk tea cup, so that the cup body of the milk tea cup is matched with the cup cover to achieve the function of sealing the cover, most of the prior art adopts a blow molding mode to produce a bottle embryo with threads, the blow molding period is longer, the production efficiency is lower, and if an injection mold is adopted to produce the milk tea cup product, the structure inside the mold is required to be optimized and upgraded. Disclosure of Invention The utility model aims at solving the problems existing in the prior art, and provides an injection mold of a threaded milk teacup, which aims at solving the technical problems that: how to enable an injection mold to produce a threaded teatcup product. The injection mold for the threaded milk tea cup comprises a top plate, a flow dividing plate, a fixed mold plate, a movable mold plate and a bottom plate which are sequentially arranged, wherein the fixed mold plate is provided with a forming part protruding to one side of the movable mold plate, an annular part in sliding connection is arranged in the movable mold plate, the annular part is circumferentially arranged at the bottom of the forming part, a forming cavity is arranged at the connecting part of the forming part, the fixed mold plate and the annular part, a formed cup body is arranged in the forming cavity, surrounding threads are arranged on the outer side wall of one end of the cup body, a forming groove corresponding to a thread structure is formed in the inner wall of the annular part, a push plate in sliding connection is arranged in the bottom plate, a plurality of push rods fixedly connected are arranged on the push plate, and one end of each push rod extends into the movable mold plate and is fixedly connected with the annular part. In the scheme, after plastic raw materials are injected into a forming cavity and cooled and formed, a cup body part of a cup body is formed between a forming part and a movable template, a cup mouth part on the cup body is formed between an annular part and the forming part, a thread structure integrally connected with the cup body can be formed on the cup body due to the fact that a forming groove structure is arranged on the inner wall of the annular part, when the movable template is separated from a fixed template, a push plate in the bottom plate is pushed to move to one side close to the movable template, the push plate can drive the push plate to move, so that the annular part is ejected from the bottom of the forming part, the annular part carries the formed cup body to be separated from the forming part to finish demoulding, and finally the cup body is taken out from the inside of the forming part to finish injection moulding. In the injection mold of the threaded milk tea cup, the forming part is in a truncated cone shape with a narrow upper part and a wide lower part, a push rod in sliding connection is arranged in the forming part, and the push rod can be pushed out upwards from the inside of the forming part. The structure of the forming part is convenient for demolding the cup body, and the ejector rod is positioned at the bottom of the body and can push the cup body to move.
