Description

Secondary core-pulling device for plastic mold sliding block

Technical Field

The utility model belongs to the technical field of plastic mold produces, concretely relates to plastic mold slider secondary device of loosing core.

Background

In order to meet the use and assembly requirements of the product, the plastic product is designed with a required buckling position or an undercut position. For a product in a mold manufacturing process, a slider structure is usually used for realizing smooth demolding of the product in a buckling position or an undercut position. However, when the product has a plurality of shapes on the sliding block, the release resistance between the product and the sliding block is very large, and the product may be pulled apart when the mold is opened. The common slide block structure can not meet the normal production requirement.

SUMMERY OF THE UTILITY MODEL

To the aforesaid not enough the utility model provides a plastic mold slider secondary device of loosing core, the device decomposes from the type resistance, reduces step by step from the type resistance, reaches safety from the type purpose.

The utility model provides a device that technical problem adopted is equipped with the take-up housing, and the take-up housing passes through spacing screw and links to each other with the take-up housing, is equipped with the spring on the take-up housing, and the spring setting still is equipped with guide pillar, slider mold insert in this device on the contact surface that the take-up housing is close to the take-up housing, and guide pillar and slider mold insert all stretch into in the take-up housing and the take-up housing.

Furthermore, the slider seat and the slider head are adjacently arranged in the horizontal direction.

Furthermore, the sliding block seat is L-shaped, and the horizontal arm is provided with a through hole matched with the inclined guide post for use.

Furthermore, one end of the guide pillar on the side surface of the sliding block seat and one end of the sliding block insert are provided with wear-resistant pieces for stabilizing the sliding block insert and the guide pillar.

Furthermore, the slide block insert is of a strip-like cubic structure, and bulges are arranged at two ends of the slide block insert.

Further, the inclined guide post is connected with a forming machine.

Further, the spring is arranged below the slide block insert.

Furthermore, the sliding block seat, the sliding block head and the sliding block insert are all made of stainless steel.

The working process is as follows: when the mold is opened, the forming machine provides power, the inclined guide post moves upwards to drive the slider seat to move leftwards, the slider insert fastened on the slider seat synchronously moves leftwards, the slider insert is guided by the bulge at the rear end of the slider insert and the guide groove of the slider seat, and the slider insert keeps the position immovable under the action of release resistance and the spring. After the slider seat moves the core pulling for a certain distance leftwards, the limiting screw is pulled to drive the slider head to start moving leftwards to be separated from the product. When the die is closed, the forming machine provides power, the inclined guide post moves downwards to drive the slider seat to move rightwards, the slider seat drives the slider insert and the slider head to move rightwards together, the spring is compressed until the slider insert resets, and the slider seat continues to drive the slider insert to move rightwards until all the slider insert resets.

Has the advantages that: the utility model discloses simplify the plastic mold slider structure of loosing core, reduced the plastic mold volume, realized the function that single slider secondary was loosed core.

The novel anti-wear sliding block comprises a sliding block seat 1, a sliding block 2, a limiting screw 3, a wear-resistant plate 4, a guide pillar 5, a sliding block insert 6, an inclined guide pillar 7 and a spring 8.

Detailed Description

The present invention will be further described with reference to the following examples.

Example 1

This embodiment is equipped with take-up housing 1, and take-up housing 1 links to each other with take-up housing 2 through spacing screw 3, is equipped with spring 8 on the take-up housing 1, and spring 8 sets up on the contact surface that take-up housing 1 is close to take-up housing 2, still is equipped with guide pillar 5, slider mold insert 6 in this device, and guide pillar 5 and slider mold insert 6 all stretch into in the take-up housing 1 and in the take-up housing 2. Wherein the slider seat 1 and the slider head 2 are adjacently arranged in the horizontal direction. The slider seat 1 is L-shaped, and the horizontal arm is provided with a through hole matched with the inclined guide post 7 for use. And one end of the guide post 5 on the side surface of the sliding block seat 1 and one end of the sliding block insert 6 are provided with wear-resistant pieces 4 for stabilizing the sliding block insert 6 and the guide post 5. The slide block insert 6 is of a strip-like cubic structure, and bulges are arranged at two ends of the slide block insert 6. The inclined guide post 7 is connected with a forming machine. The spring 8 is arranged below the slide block insert 6. The sliding block seat 1, the sliding block head 2 and the sliding block insert 6 are all made of stainless steel.

Example 2

The working process is as follows: as shown in fig. 3, when the mold is opened, the forming machine provides power, the inclined guide post 7 moves upwards, the inclined guide post drives the slider seat 1 to move leftwards, the slider insert 6 fastened on the slider seat 1 moves leftwards synchronously, the slider insert 2 is guided by the bulge at the rear end of the slider insert 2 and the guide groove of the slider seat 1, and the slider insert 2 keeps the position immovable due to the release resistance and the action of the spring 8.
