Description

Secondary delay core-pulling slider device for injection plastic mold

Technical Field

The utility model belongs to the technical field of injection plastic mould, the utility model relates to an injection plastic mould secondary delays slider device of loosing core.

Background

The core pulling of the sliding block in the injection mold generally adopts an inclined guide pillar or hydraulic core pulling, and the sliding block only acts once. However, many times, the injection molding process is difficult due to the special characteristics of the product or the appearance of the product with the requirement of etching.

Disclosure of Invention

The utility model aims at overcoming not enough among the prior art, providing an injection plastic mould secondary delays slider device of loosing core, the device has simple structure, and the simple operation realizes that the slider can realize that the secondary delays to loose core, and the slider divides the characteristics of twice action.

The utility model provides a technical scheme that its technical problem adopted is: a secondary delay core-pulling slider device for an injection plastic mold comprises a movable mold plate, a fixed mold block, a product molding area, an inner slider, an outer slider, a spring, an inclined guide pillar, a movable mold block and an inner slider insert pin; a fixed module is arranged in the fixed template, and a movable module and an outer sliding block are arranged on the movable template; a product forming area is arranged on the movable module; an inner sliding block is arranged in the outer sliding block, inclined guide post holes are formed in the inner sliding block and the outer sliding block, and the inclined guide posts are arranged in the inner sliding block and the outer sliding block of the fixed template in an inserting mode; an inner slide block insert pin is arranged in the inner slide block in the horizontal direction; the spring is arranged on the inner slide block insert pin; one end of the inner slide block insert pin in the horizontal direction protrudes out of the inner slide block and is connected with a product forming hole arranged on a product forming area, and the other end of the inner slide block insert pin is fixed on the inner wall of the inner slide block; the movable template is connected with the fixed template through a wedging block.

Furthermore, the inclined guide post hole on the outer sliding block is a long round hole. The diameter of the inclined guide pillar hole arranged on the inner sliding block is smaller than that of the inclined guide pillar hole arranged on the outer sliding block.

Furthermore, the inner sliding block is provided with a bolt.

Furthermore, a screw is arranged on the wedging block.

Furthermore, the inner slide block and the outer slide block can move in the horizontal direction.

Furthermore, the included angle between the inclined guide post and the vertical direction is 13-22 degrees.

When the mold is opened at the beginning, the inclined guide post hole on the outer slide block is made into the long round hole, the outer slide block is not moved, the inner slide block is withdrawn towards the right side under the action of the inclined guide post and the compression spring, and the outer slide block is still attached to a product under the action of the spring between the insert pin of the inner slide block and the outer slide block. Along with the increase of the mold opening distance, the outer slide block starts to move to the right. So that the movement between the inner slide and the outer slide is delayed by a time corresponding to the distance L.

Compared with the prior art, the utility model beneficial effect who has is:

(1) the device provided by the utility model can lead the slide block at the side part to move twice, and the slide block at the side part comprises an outer slide block and an inner slide block; because of the requirement of the surface decoration of the product, if only one sliding block is arranged on the forming hole site and the side surface for forming, the hole site always has pull damage, the core is pulled twice, the hole site is firstly pulled out, and then the large side surface is pulled out, so that the problem is solved. The side part extracting slide block moves twice to avoid the defect of the product caused in the process of extracting the slide block.

(2) Due to the delay of the action of the sliding block, the outer sliding block can press the side face of the product instantly at the initial stage in the die sinking process, the product is fixed on the movable die block, the inner sliding block is firstly pulled out, and the phenomenon that the product slightly leaves the movable die block before pulling out the core to cause the broaching of the hole is avoided.
