Double-reversing inwards-withdrawing type T-shaped groove core-pulling mechanism for injection mold

Abstract

The invention relates to a double-reversing inwards-withdrawing type T-shaped groove core-pulling mechanism for an injection mold. The double-reversing inwards-withdrawing type 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 press strip, a first wear-resistant plate, a first press strip screw, a second wear-resistant plate, a second inner core-pulling slide block body, a second press strip screw and a second press strip. The central double-T-shaped groove wedge block serve as a core-pulling power component of the core-pulling mechanism and is mounted on a mold fixed mold seat plate through screws. The first press strip, the first wear-resistant plate, the second wear-resistant plate and thesecond press strip are mounted on a mold cavity through screws. The first press strip plays a role in guiding the first inner core-pulling slide block body, and the second press strip plays a role inguiding the second inner core-pulling slide block body. The central double-T-shaped groove wedge block is linked with the first inner core-pulling slide block body and the second inner core-pulling slide block body through T-shaped grooves. The double-reversing inwards-withdrawing type T-shaped groove core-pulling mechanism is reasonable in structural design, compact in structure, stable in work and safe and reliable to use.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 2015101539057, the invention name: a double-reverse retractable T-slot core-pulling mechanism for injection molds, and the application date: April 2, 2015. technical field [0002] 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 [0003] 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 c...

[0003] 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
