Abstract

The invention provides a simple secondary ejection device, which comprises a bottom plate, a movable template and a first thimble; a movable die core is arranged at the upper end of the movable template; the bottom plate is provided with a groove; one end of a spring is arranged on the groove; the cup head of the lower end of the first thimble is provided with a blind hole; the other end of the spring is arranged in the blind hole of the first thimble; a thimble plate matched with the cup head is arranged on the cup head of the first thimble; a surface pin plate is arranged at the upper end of the thimble plate; the first thimble passes through the thimble plate, the surface pin plate, the movable template and the movable die core; a second thimble is arranged at the other end of the thimble plate; the second thimble passes through the surface pin plate, the movable template and the movable die core; and the thimble plate and the surface pin plate are arranged in the bottom plate and the movable template. By reducing the thimble plate, the device can realize secondary ejection and saves the cost.

Description

technical field [0001] The invention relates to a simple secondary ejecting device. Background technique [0002] In plastic products, there are often some undercut structures that do not require side core pulling to demould, but directly use forced demoulding. In most cases, the action of forced demoulding needs to be ejected twice to achieve. The traditional secondary ejection action is often realized by four ejector plates on the mold, and the structure of four ejector plates will virtually increase the total thickness and complexity of the mold. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a simple secondary ejector. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The simple secondary ejection device includes a bottom plate, a movable template and a first thimble. A movable mold core is installed on the upper end of the...
