Problems solved by technology
[0003] In order to make the sealing between the movable mold and the fixed mold better, it is necessary to use multiple fixing parts to tightly connect the moving mold and the fixed mold during installation, because the user needs to install these fixing parts before injection molding, and after the pipe fittings are cooled and formed , it is necessary to disassemble these fixing parts before the pipe fittings can be taken out, which brings inconvenience to the user when loading and unloading the mold, thereby reducing the work efficiency of the operator

The invention discloses a pipe fitting injection mould. The pipe fitting injection mould comprises a fixed mould and a movable mould, wherein the middle of the upper part of the fixed mould is provided with a tubular groove, two sides of the tubular groove are symmetrically provided with fixing rods, and the fixing rods are vertically arranged and fixedly connected with the fixed mould; the movable mould is composed of two arc-shaped plates with semicircular cross sections, the two arc-shaped plates jointly form a tube cavity, the inner diameters of the tube cavity and the tubular groove are the same, a forming cavity for forming a pipe fitting is jointly formed, and fixing grooves for matching the fixing rods are formed in the arc-shaped plates; and the fixed mould is symmetrically provided with a pair of heating cavities, pressure cavities are formed in the two fixing rods, the pressure cavities communicate with the corresponding heating cavities and are filled with expansion substances. According to the pipe fitting injection mould, the high temperature of materials is utilized so that the movable mould can be in close contact to form the sealed forming cavities, and an injection molding cavity cannot need to be reinforced by an additional fixing piece, so that the mould is convenient for a user to assemble, and the working efficiency of the user is improved.
Description
technical field [0001] The invention belongs to the technical field of injection molds, in particular to an injection mold for pipe fittings. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. The injection mold for pipe fittings is generally composed of a fixed mold and a movable mold. The movable mold is tightly installed on the fixed mold and forms a tubular molding cavity together with the fixed mold. When in use, high-temperature raw materials are injected into the molding cavity. After cooling and forming, the dynamic The mold is removed to take out the formed pipe fittings. [0003] In order to make the sealing between the movable mold and the fixed mold better, it is necessary to use multiple fixing parts to tightly connect the moving mold and the fixed mold during installation, because the user needs to install these fixing parts before i...
