Quantitative injection mold

Abstract

The invention discloses a quantitative injection mold, and belongs to the technical field of molds. The quantitative injection mold comprises a base and a lower template fixed to the base, wherein thebase is provided with a first vertical plate and a second vertical plate; the lower template is provided with a movable template and a fixed template; the fixed template is provided with an upper template; the lower template is provided with a first sliding chute and a first sliding block; one end of the movable template is provided with a first sliding boss sliding in the first sliding chute; the upper template is provided with a second sliding chute and a second sliding block; the other end of the movable template is provided with a second sliding boss sliding in the second sliding chute; one end of the first sliding chute is provided with a first threaded rod; the other end of the first sliding chute is provided with a second threaded rod. The quantitative injection mold has the advantages of simple structure, convenience in operation and high practicability, and can easily change the thickness of a model to achieve the effect of quantitative injection molding.

[0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. It is known as the "mother of industry". In the prior art, The shape and thickness of the injection molding cavity are generally fixed, and all the values ​​​​of the commonly used molds are fixed during use. For example, the length, width, and thickness of the injection molded products are all constant, and can only be used for one model. Therefore, one type of mold cannot extrude products with different thicknesses. The disadvantage of such a structure is that once it is necessary to inject injection molded parts with the same shape but different thicknesses, it is necessary to replace the injection molding cavity with different thicknesses. Injection molding, on the one hand, increases the cost of the mold. On the other hand, because it takes a certain amount of time to replace the mold cavity, it also directly affects the production efficiency. The same injection mold cannot manufacture workpieces with different thicknesses, thereby reducing the cost of the injection mold. Practicality, and some jobs require the weight to be a fixed value. In the case of no change in the structure, most of them adopt the method of increasing or reducing the thickness to achieve quantitative injection molding.
