Description

Slide block mechanism for insert injection molding

Technical Field

The utility model relates to a slider device's technical field, concretely relates to dress slider mechanism that inlays the piece and moulds plastics.

Background

Usually, when an injection molding insert mold is made, the insert mold is realized by adopting the movement of an inclined guide post and a slide block, as shown in fig. 5 and 6, firstly, an insert A4 is installed on a rear mold core A5, then mold closing is started, a fixed mold core A1, an inclined guide post A2 and a brake block A3 move downwards, the inclined guide post touches a guide hole of the slide block A7, the acting force of the inclined guide post is applied to the slide block, so that the slide block is stressed, and the slide block drives an insert fixing piece A6 to move forwards, thereby fixing the insert.

Because the insert fixing piece is arranged on the sliding block and is also a moving piece, and the insert fixing piece is required to fix the insert in motion, the requirements on the insert fixing piece, the sliding block machining precision and the mold opening and closing precision are very high, hundreds of percent of matching can not be guaranteed, and the qualified rate in the production injection molding process can not be guaranteed.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned defects, the utility model aims to provide a simple structure, it is convenient to use, dress inlay piece slider mechanism of moulding plastics.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

the slide block mechanism for installing the insert for injection molding comprises a fixed mold core, a movable mold core, a bent pin and a slide block; the side surface of the fixed die core is fixedly provided with a bent pin, and the bottom surface of the fixed die core is fixedly provided with a brake block; one end of the movable mould core is provided with an insert needle, and the other end of the movable mould core is provided with a sliding block; the sliding block is connected with the insert needle through the fixed insert; the spring lock is arranged in a through hole in the side wall of the U-shaped groove at the rear part of the sliding block and is connected with a spring, the spring is connected with a pressing plate, and the pressing plate is fixed on the sliding block through a bolt.

The bending pin is a triangle, a plane and two inclined planes.

The fixed insert is T-shaped.

The utility model discloses rational in infrastructure, it is convenient to use. The slider is connected with the insert needle through the fixed insert, so that the goodness of fit is improved, the matching is convenient, the production qualification rate of the die is improved, and the slider can be popularized in production.

In the figure, the device comprises a fixed die core 1, a fixed die core 2, a bent pin 3, a brake block 4, a sliding block 5, a spring lock 6, a fixed insert 7, an insert needle 8, a movable die core 9, a spring 10, a pressing plate 11, a bolt 12, an inclined plane 13 and a plane.

Detailed Description

The present invention will be described in further detail with reference to the following drawings, and it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

As shown in fig. 1-4, the slide block mechanism for insert injection molding comprises a cavity block 1, a cavity block 8, a bending pin 2 and a slide block 4. The side surface of the fixed die core 1 is fixedly provided with a bending pin 2. The bending pin 2 is made as a triangle, a plane 13 and two inclined planes 12. Under the condition that the slide block 4 is not positioned, the two inclined surfaces 12 can more easily enter the U-shaped groove of the slide block 4 through the lock latch 5 on the slide block 4, and the straight surfaces are used for pulling the lock latch 5 on the slide block 4 to enable the slide block 4 to move. The bottom surface of the fixed die core 1 is fixedly provided with a brake block 3; one end of the movable mould core 8 is provided with an insert needle 7, and the other end is provided with a slide block 4; the slide 4 is connected with an insert needle 7 through an insert 6. The T-shaped fixed insert 6 is connected with the sliding block 4 to form a whole body, so that the simultaneous movement is realized. The elastic lock 5 is arranged in a through hole in the side wall of the U-shaped groove at the rear part of the sliding block 4, the elastic lock 5 is provided with a spring 9, the spring 9 is provided with a pressing plate 10, and the pressing plate 10 is fixed on the sliding block 4 through a bolt 11.

In the production injection molding process, an insert needle 7 is placed in a positioning insert hole of a movable mold core 8, a slide block 4 is manually pushed to enable a fixed insert 6 and the insert needle 7 which are arranged on the slide block 4 to be assembled in place, a fixed mold core 1, a bent pin 2 and a brake block 3 are closed downwards, the inclined plane acting force of the bent pin 2 is exerted on an elastic lock 5, the elastic lock 5 is forced to return into the slide block 4, after the bent pin 2 is smoothly put in place, the bent pin 2 is separated from the elastic lock 5 and then is rebounded to be in place under the reaction force of a spring 9, after the injection molding is finished, the movable mold core 8 of the movable mold is retreated, the plane of the bent pin 2 acts on the plane of the elastic lock 5, the slide block 4 is forced to move backwards, the slide block 4 drives the fixed insert 6 to move, the fixed insert 6 is separated from the insert.
