Injection mold rotary slider mechanism with locking structure

Abstract

The invention discloses an injection mold rotary slider mechanism with a locking structure. The injection mold rotary slider mechanism comprises a male mold arranged on a rear mold, the male mold is provided with a slider, the male mold is provided with an arc groove for the slider to rotationally slide, the male mold is provided with a driving member for driving the slider to slide, and one sideof the male mold is slidably connected with a limiting member for restricting the slider from sliding out of a mold cavity; a front mold is provided with a linkage piece for linking the limiting member to slide to end clamping when mold opening is carried out, in the product specific molding process, the limiting member is used for conducting rotary limiting on the slider, the slider can be stablyin the current state in the molding process, the quality in the product molding process is ensured, the product quality is effectively improved, and the unqualified rate is reduced; and mold openingis carried out after product molding, the linkage piece is used for linking the limiting member to move to end limiting to the slider while mold opening is carried out, successive rotary segregation of the slider is facilitated, and product can be subjected to mold releasing smoothly.

Description

technical field [0001] The invention relates to the field of injection molds, more specifically, it relates to a rotary slider mechanism of an injection mold with a locking structure. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. It mainly includes a front mold and a rear mold. A convex mold and a concave mold are respectively set on the front mold and the rear mold. The punch and the die form a cavity for injection molding. The heated and melted plastic is injected into the cavity formed by the punch and the die by the injection molding machine under high pressure, and the molded product is obtained after cooling and solidification. [0003] Different molds are required for different products, and existing products have internal hollows, such as the oil filler port housing on a car, such as figure 1 As shown, it includes a main body 21, an...

Problems solved by technology

[0003] Different molds are required for different products, and the existing products have internal hollows, such as the oil filler port housing on the car, such as figure 1 As shown, it includes a main body 21, and one side of the main body 21 is hollowed out to form a hollow part 22, which needs to be realized by rotating the slider on the punch during the forming process, so that when the product is demoulded after the forming is completed , through the driving part to drive the rotary slider to rotate to come out, so that the product can be demolded smoothly, but in the specific forming process, there will be displacement of the rotary slider under the injection pressure, which will eventually lead to poor surface quality of the formed product and make the product shape Poor quality increases the failure rate
