Description

Die structure of oblique slider lateral core pulling

technical field

The utility model relates to a mold, in particular to a lateral core-pulling mold structure of an inclined slider.

Background technique

When the plastic product has inner and outer holes or undercuts that are different from the mold opening direction, the plastic product cannot be demolded directly, and the core with the side hole or undercut must be made into a movable core. Before demoulding, pull the movable core to the side to make it leave the side hole or undercut of the product, and then push out the product. The existing mold structure for making this type of plastic products is: a fixed template, a fixed mold insert connected with the fixed template, a movable template, and a movable mold insert connected with the movable template. There is a movable core between the mold inserts. The shape of one end of the movable core is consistent with the side hole or undercut shape on the side of the plastic product, and the other end is connected to the inclined slider connected with the slideway of the movable template. The inclined slider A spring is arranged between the moving mold insert, and a limiting inclined block is fixed on the fixed template, and the inclined surface on the limiting inclined block matches the inclined surface on the inclined sliding block. When the movable template drives the movable mold insert and the fixed mold insert to close the mold, a cavity is formed in the middle, and the inclined surface on the limiting inclined block matches the inclined surface on the inclined sliding block, so that the inclined sliding block drives the movable core. Move to the cavity, after injection molding, when the mold is opened, the spring will push the inclined slider and the movable core out, so that the end of the movable core is separated from the plastic product, and then the product is demoulded. This method of relying on the elastic force of the spring to directly push out the inclined slider and the movable core has the following disadvantages: the spring often bends during use, especially when the inclined slider leaves the movable mold insert, the exposed part of the spring may fall Bending, if this happens, the spring will be stuck when the mold is closed again, making the mold unable to work, which has the disadvantages of many faults, frequent maintenance, and low work efficiency.

Contents of the invention

The purpose of the utility model is to provide a lateral core-pulling mold structure of an oblique slider with flexible and reliable action, no stuck phenomenon, low failure rate, reduced maintenance time and high production efficiency, so as to overcome the shortcomings of the prior art.

The lateral core-pulling mold structure of the oblique sliding block of the utility model comprises a fixed template, a fixed mold insert connected with the fixed template, a movable template, and a movable mold insert connected with the movable template; There is a movable core between the movable mold inserts, and the movable core is connected with the inclined slider; the inclined slider and the movable template are connected by a slideway; the limit inclined block is fixed on the fixed template, and the limit inclined block The inclined surface is matched with the inclined surface on the inclined slider; the inclined guide post is fixed on the fixed template, and the inclined guide post is located in the inclined hole on the inclined slider; a hole is processed in the inclined slider, and the hole is set There is a spring; it is characterized in that: one end of the ejector rod is located in the hole and abuts against the end of the spring, and the other end of the ejector rod is located outside the hole and abuts against the movable mold insert.

In the lateral core-pulling mold structure of the oblique slider of the utility model, the fixed template is fixed with an oblique guide column fixing block, and the oblique guide column is fixed on the oblique guide column fixing block.

In the lateral core-pulling mold structure of the oblique slider of the utility model, since obliquely arranged oblique guide columns are fixed on the fixed template, the oblique guide columns are located in the oblique holes on the oblique slider, and holes are processed in the oblique slider. There is a spring in the hole, one end of the ejector rod is located in the hole and abuts against the end of the spring, the other end of the ejector rod is located outside the hole and abuts against the movable mold insert, when the movable template drives the movable mold insert, When the inclined slider and the movable core move down, due to the existence of the inclined guide post, spring and ejector rod, the inclined slider moves outward while moving down, thereby driving the movable core to be drawn out, so that the product can be demoulded smoothly and overcomes the In the prior art, the exposed spring is prone to bending, deformation and thus stuck, which reduces the maintenance time of the mold and improves the work efficiency. The structure of the mold is flexible and reliable.

Detailed ways

As shown in the figure: 9 is a fixed template, and a fixed mold insert 3 is connected with the fixed template 9, and 12 is a movable template, and a movable mold insert 6 is connected with the movable template 12. 4 is a movable core, which is located in the joint Between the fixed mold insert 3 and the movable mold insert 6 after the mold, the shape of the left end of the movable core 4 matches the side concave shape of the plastic product 5, and the other end of the movable core 4 is connected with a boss Hook is fixed on the inclined slide block 7. The inclined slide block 7 is connected with the moving template 12 slideways. On the fixed formwork 9, the limit inclined block 10 is fixed by bolts 8, and the inclined surface on the limit inclined block 10 cooperates with the inclined surface on the inclined slide block 7.

On the fixed template 9, a fixed block 2 of the inclined guide post is fixed, and the end of the inclined guide post 1 arranged obliquely is fixed on the fixed block 2 of the inclined guide post. The oblique guide post 1 is located in the oblique hole on the oblique slider 7 . On the moving template 12, the limit block 11 is screwed to cooperate with the end of the inclined slide block 7.

A hole is processed in the inclined slider 7, and a spring 14 is arranged in the hole. One end of the ejector rod 13 is located in the hole and abuts against one end of the spring 14, and the other end of the ejector rod 13 is located outside the hole and connected to the movable mold. The insert 6 leans against, and a plug 15 is screwed on the inclined slider 7 for leaning against the other end of the spring 14 .

When the movable template 12 drives the movable mold insert 6 and the fixed mold insert 3 to close the mold, a cavity is formed in the middle, and the inclined surface on the limiting inclined block 10 is matched with the inclined surface on the inclined sliding block 7 to make the oblique slide The block drives the movable core to move to the cavity. At this time, the inclined slider 7 slides relative to the inclined guide post 1. After injection molding, when the mold is opened, the movable template 12 drives the mold insert 6, the inclined slider 7, the movable type The core 4 and the product 5 move down. Due to the existence of the inclined guide post 1, the spring 14 and the ejector rod 13, the oblique slider 7 is forced to drive the movable core 4 to move to the right, so that the movable core 4 is separated from the product 5, which is used for demoulding. get ready.
