Problems solved by technology

At present, since the fixed mold core and the movable mold core cannot be adjusted after being fixed, after the mold has been used for a period of time, due to various reasons, the fixed mold core and the movable mold core will be misaligned during production, resulting in the docking between the movable mold core and the fixed mold core. There is an error; or there is a certain error in the installation of the mold, so that there is an error in the docking between the movable mold core and the fixed mold core; resulting in the misalignment of the injection cavity formed between the movable mold core and the fixed mold core, and the surface smoothness of the injection molded product. low, thus affecting the quality of the product

Embodiment Construction

[0039] The accompanying drawings are all schematic diagrams of the implementation of the present invention, so as to understand the principle of structural operation. The specific product structure and proportional size can be determined according to the use environment and conventional technology.

[0040] Such as figure 1 , 2 As shown, it includes a fixed mold 1 and a movable mold 2, wherein the fixed mold 1 is installed on the fixed mold 1 plate of the injection molding machine, and the movable mold 2 is installed on the movable mold 2 plate of the injection molding machine to cooperate with the fixed mold 1.

[0041] Such as Figure 4 As shown, the above-mentioned fixed mold 1 includes a fixed mold base 3, a fixed mold core 5, and a positioning angle iron 8, wherein as image 3 As shown, the fixed mold core 5 with the first injection cavity 6 is embedded in the first positioning groove 9 fixedly installed on the side of the fixed mold base 3; as Figure 4 ,5 As shown, ...

Abstract

The invention belongs to the technical field of injection molds, and particularly relates to an adjustable injection mold. The adjustable injection mold comprises a fixed mold and a movable mold, wherein the fixed mold is mounted on a fixed mold plate of an existing injection molding machine, and the movable mold is mounted on a movable mold plate of the existing injection molding machine to be matched with the fixed mold. By twisting a rotary knob, a sliding block located in a guiding rail drives a movable mold core through a hinge pin to get close to positioning angle iron, when the side face and the upper end face of the movable mold core are tightly attached to the positioning angle iron, the positioning angle iron finally completes accurate positioning butt-joint of the movable mold core and a fixed mold core, and thus a first injection molding cavity and a second injection molding cavity are in butt joint completely and are not staggered; and the positioned movable mold core is subjected to fastening positioning through four fastening bolts, thus the movable mold core does not move in the injection molding process, a transition position, on a product, of the movable mold coreand the fixed mold core is smoother, the situation that the movable mold core and the fixed mold core are staggered, and consequently the product is unqualified is avoided, the pass rate of the product is increased, and the quality of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to an adjustable injection mold. Background technique [0002] At present, the traditional injection mold is a tool for producing plastic products. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. The current fixed mold includes a fixed mold base and a fixed mold core, and the fixed mold core is fixed on the fixed mold base through fasteners; the movable mold includes a movable mold base and a movable mold core, and the movable mold core is fixed on the movable mold base through faste...
