A separate oblique core-pulling mechanism for automobile lamp lamp body mold

Abstract

The invention provides an automobile lamp body die separating type inclined core-pulling mechanism. The separating type inclined core-pulling mechanism comprises a fixed die insert mounted on a fixed die plate and a movable die insert mounted on a movable die plate, wherein a movable die sliding block is arranged on the movable die insert, the movable die sliding block is connected with an upper-lower movable block through a limiting mechanism, an elastic component is sleeved on the upper part of the limiting mechanism, the lower end of the upper-lower movable block is provided with a sliding chute, an inclined hole insert pin is slidingly arranged in the sliding chute, the upper end of the upper-lower movable block is provided with a nylon die locker, a nylon die locker bush is sleeved on the nylon die locker, and the nylon die locker bush is fixedly arranged on the fixed die insert. According to the automobile lamp body die separating type inclined core-pulling mechanism, the technical difficulties that the complex cylinder core-pulling mechanism of the traditional die needs frequent maintenance and the default rate is high are solved; the injection molding period is further shortened without fussy cylinder core-pulling action, the production cost is reduced, and good economic value is realized.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a separable oblique core-pulling mechanism for lamp body molds of automobile lamps. Background technique [0002] Using injection molds to produce plastic products, such as car lamp accessories, etc., when the side of the lamp body is as Figure 4 As shown, when there are upper and lower inclined hole features 19 and 20 for installing the dimming screw, since the two inclined hole features are coaxial, there is no demoulding angle, and the core pulling distance of the inclined hole is very long, the mold opening and closing action is limited. sequence, so it is difficult to mold the product. Traditional molds generally have multiple oil cylinder core-pulling mechanisms, and some oil cylinder core-pulling mechanisms are also built on the moving slider, or are realized by multiple mold parting mechanisms, resulting in poor mold strength and poor operating stability of the mechanism....

[0002] Using injection molds to produce plastic products, such as car lamp accessories, etc., when the side of the lamp body is as Figure 4 As shown, when there are upper and lower inclined hole features 19 and 20 for installing the dimming screw, since the two inclined hole features are coaxial, there is no demoulding angle, and the core pulling distance of the inclined hole is very long, the mold opening and closing action is limited. sequence, so it is difficult to mold the product

Traditional molds generally have multiple oil cylinder core-pulling mechanisms, and some oil cylinder core-pulling mechanisms are also built on the moving slider, or are realized by multiple mold parting mechanisms, resulting in poor mold strength and poor operating stability of the mechanism. Tooling costs are high
