Double-opposite-direction inward-folded T-shaped groove core pulling mechanism of injection mold

Abstract

The invention provides a double-opposite-direction inward-folded T-shaped groove core pulling mechanism of an injection mold. The double-opposite-direction inward-folded T-shaped groove core pulling mechanism comprises a central double T-shaped groove wedge block, a first inner core pulling slide block body, a first presser bar, a first wear-resisting plate, a first presser bar screw, a second wear-resisting plate, a second inner core pulling slide block body, a second presser bar screw and a second presser bar. By adopting the double-opposite-direction inward-folded T-shaped groove core pulling mechanism of the technical scheme, the demand for realizing the core pulling on a fixed mold side and realizing the core pulling demolding in opposite directions on the same straight line inside plastic products can be reliably satisfied, the problems of complexity in designing and machining the traditional core pulling mechanism can be solved, and the double-opposite-direction inward-folded T-shaped groove core pulling mechanism is novel in design, convenient to use and stable, safe and reliable in work.

Description

technical field [0001] The invention relates to the field of mold structure design, and specifically designs a double-reverse retractable T-shaped slot core-pulling mechanism for an injection mold. Background technique [0002] When plastic products are molded using a slider-side core-pulling mechanism, there are generally two situations, that is, core-pulling on the side of the movable mold and core-pulling on the side of the fixed mold, and core-pulling on the side of the movable mold. The design is relatively easy, but the design of the core-pulling mechanism on the side of the fixed mold is more complicated; when pulling the core, according to the direction of the core-pulling, it can be divided into core-pulling away from the center of the mold and core-pulling toward the center of the mold; core-pulling away from the mold The core is generally called the outer core, and the core closer to the mold is the inner core; some plastic products, due to the limitation of the p...

[0002] When plastic products are molded using a slider-side core-pulling mechanism, there are generally two situations, that is, core-pulling on the side of the movable mold and core-pulling on the side of the fixed mold, and core-pulling on the side of the movable mold. The design is relatively easy, but the design of the core-pulling mechanism on the side of the fixed mold is more complicated; when pulling the core, according to the direction of the core-pulling, it can be divided into core-pulling away from the center of the mold and core-pulling toward the center of the mold; core-pulling away from the mold The core is generally called the outer core, and the core closer to the mold is the inner core; some plastic products, due to the limitation of the product structure design, need to pull the core on the side of the fixed mold when molding, and at the same time need the inner core. , and sometimes when the opposite direction on the same line on the product needs to be reversed and core-pulled at the same time, it is necessary to consider not only the limitation of space layout, but also the rationality of the movement of the mold mechanism and many other factors when designing the mold structure. Difficult, in view of this, in combination with some types of products, such as mobile phone frames and other products, when the injection molding is performed on the fixed mold side, core-pulling is performed on the side of the fixed mold, and two different parts on the straight line of the core-pulling direction need to be core-pulled at the same time. , the design of the existing conventional T-slot core-pulling slider mechanism has been improved, and the use of the slope T-slot in the design of the slider can provide both core-pulling power and locking pressure, and can strictly control the pumping. Core distance and other characteristics, designed the mechanism of the present invention - a double reverse inward T-slot core-pulling mechanism for injection molds, which can reliably complete the core-pulling and demoulding needs of such products. The mechanism is novel in design, easy to use, and easy to work. Stable, safe and reliable
