[0002] For example, the public number CN204773338U name is an injection mold produced by a mold with upper and lower covers for box-like parts. The mold cavity and the second concave mold cavity, the first convex module and the second convex module are arranged in the male mold core, the first concave mold cavity matches the first convex module, and the second concave mold cavity matches the second convex module ;The parting surface of the injection mold is composed of multiple planes with different heights, and the surfaces of the two sets of molded parts that are higher than the female template and the male template are offset inward by 0.3-0.7mm; Correspondingly, matching tiger mouths are provided; the pouring of the smaller set of molded parts in the two sets of molded parts adopts an S-shaped runner, so that the pouring time of the two sets of molded parts is equal; the disadvantage of this utility model is that it cannot be used according to different Adjust the size of injection molding castings according to the needs of use, and reduce the generation of air bubbles in castings

Abstract

The present invention relates to a mould, more specifically an adjustable injection mold, including a device bracket, a forming mold I, a demoulding link, a demoulding mechanism, an adjustment mechanism, a forming mold II, an extrusion mechanism, a pre-tensioning mechanism and an injection mold The two demoulding mechanisms can press the four demoulding connecting rods close to each other so that the forming mold Ⅰ is stuck on the forming mold Ⅱ, and the injection tube is injected into the injection cylinder, and the injection cylinder is directed towards the forming mold Ⅰ and the forming mold Ⅱ. Injection molding between molding dies Ⅰ and Ⅱ when the injection molding objects reach a certain height, push the extrusion mechanism to extrude the compression spring Ⅲ to slide in the molding mold Ⅱ, the level of the extrusion mechanism changes and squeeze the injection molding objects The pressure reduces the generation of air bubbles, and the level of the adjustment mechanism in the molding mold I can be adjusted before injection molding to adjust the size of the casting.
