Problems solved by technology

At present, since the fixed mold core and the movable mold core cannot be adjusted after being fixed, if there is an error in the production of the fixed mold and the movable mold or a certain error in the installation, the injection cavity formed by the fixed mold core and the movable mold core will exist. Accuracy problem, the precision of the injection molded workpiece is low, which affects the manufacturing quality

Embodiment Construction

[0036] 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.

[0037] like figure 1 , 2 As shown, it includes a movable mold 2 and a fixed mold 1, 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. Complete injection molding.

[0038] like image 3 , 4 As shown, the above-mentioned movable mold 2 includes a movable mold base 10, a movable mold core 17, a fastening bolt 19, a second hinge pin 20, a push plate 21, a first hinge pin 22, a slider 23, an adjusting screw 24, and a knob 25, Among them such as Figure 9 As shown, there is a second positioning groove 1...

Abstract

The invention belongs to the technical field of injection molds and particularly relates to an injection mold. The injection mold comprises a movable mold and a fixed mold. The fixed mold is mounted on a fixing mold plate of an injection molding machine. The movable mold is mounted on a movable mold plate of the injection molding machine and matched with the fixed mold to complete injection molding. According to the injection mold, a rotary knob is rotated, and a sliding block drives a movable mold core to move close to locating angle iron through a push plate and a second hinge-joint pin; when the side face and the upper end face of the movable mold core are closely attached to two faces of an inner corner of the locating angle iron correspondingly, precise locating and butt joint of themovable mold core and a fixed mold core are achieved though the locating angle iron, so that a first injection molding cavity and a second injection molding cavity are completely in butt joint withoutbeing staggered; the located movable mold core is fastened and located through four fastening bolts and not shifted in the injection molding process, and thus, the transitional position, formed by the movable mold core and the fixed mold core, of an injection molding product can be smoother; the problem that the product is unqualified due to the fact that the movable mold core is staggered from the fixed mold core is avoided; and the product qualification rate is increased, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to an 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 fasteners super...
