Abstract

The invention provides a full-circle inner circumferential demoulding mechanism. The full-circle inner circumferential demoulding mechanism comprises an ejector insert pressure ring, an insert ejectorplate, a backing plate, a base plate, an ejector spring, a pull rod, a central core, a primary demoulding inner sliding block, a primary core pulling guide pressure rod, a pressing ring screw, and asecondary oblique ejector rod. The mechanism can realize the demoulding of an inner whole circle groove; the demoulding process is carried out in two times, the demoulding of a partial region of the inner circle groove is carried out by using an inner core-pulling sliding block at the first time, the domoulding of the residual part is completed through an oblique ejector at the second time. The overall structure of the mechanism is reasonable and compact in design, the parts work stably, and thus the demoulding mechanism is safe and reliable, convenient to install and disassemble and low in manufacturing cost so that the mechanism is conducive to reduce the overall cost of moulds.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a full-circle inner circumference demoulding mechanism. Background technique [0002] Such as figure 1 As shown, the product is a cover with a full-circle undercut. When designing the injection mold, it is difficult to realize the demoulding of the full-circle underturn. Therefore, it is necessary to design a special full-circle inner groove demoulding mechanism. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a demoulding mechanism for the inner circumference of a full circle, which has reasonable design, compact structure, stable operation, safety and reliability, and is convenient to use; in order to solve the above-mentioned existing technical problems, the present invention adopts the following scheme: a. A demoulding mechanism for the inner circumference of the whole circle, including ejection ins...
