Demolding mechanism of air conditioner air inlet filter element cover injection mold

Abstract

The invention discloses a demolding mechanism of an air conditioner air inlet filter element cover injection mold. The demolding mechanism comprises a lower mold and a big slider for forming the sideface of the product. The upper surface of the lower mold is provided with a slide groove. The big slider is in sliding fit with the interior of the slide groove. The demolding mechanism further comprises a small slider base, a pull rod and an element pulling inclined top for forming a barb in a protruding column. The bottom surface of the big slider is provided with an opening groove with a downward opening. The small slider base is located in the slide groove and is in sliding fit with the interior of the opening groove. The big slider is internally provided with a channel. The channel communicates with the opening groove and the barb. One end of the pull rod is arranged at the upper end of the small slider base. The other end of the pull rod penetrates through the channel to be connectedwith the element pulling inclined top. The axis of the channel is perpendicular to the element pulling direction of the barb. A distance is formed between the small slider base and the opening groove. The demolding mechanism of the air conditioner air inlet filter element cover injection mold is high in reliability and small in occupied space.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a demoulding mechanism for an injection mold of an air-conditioning intake filter core cover. Background technique [0002] The side of the air conditioner intake filter cover is provided with a protruding post protruding from the air conditioner intake filter cover, and the lower end of the protruding post is provided with a barb. The structure at this position has barbs because it is a functional area structure, as shown in Figure 5. According to the current situation With technology, there are two directions of barbs on the side of the product at the same time. It is necessary to design the slider + inclined top structure to form. According to the conventional method, the large slider will be made with a small slider, and the small slider will be equipped with a dovetail core-pulling structure, and the spring will be added inside. The small slider ejects the mechanism, so the in...

[0002] The side of the air conditioner intake filter cover is provided with a protruding post protruding from the air conditioner intake filter cover, and the lower end of the protruding post is provided with a barb. The structure at this position has barbs because it is a functional area structure, as shown in Figure 5. According to the current situation With technology, there are two directions of barbs on the side of the product at the same time. It is necessary to design the slider + inclined top structure to form. According to the conventional method, the large slider will be made with a small slider, and the small slider will be equipped with a dovetail core-pulling structure, and a spring will be added inside to assist. The small slider ejects the mechanism, so the internal structure is unstable, the spring has fatigue strength, there is a risk of failure, and the reliability is poor. At the same time, the small slider and its dovetail groove are on the large slider, which takes up a lot of space and affects the performance of the large slider. strength
