Description

mould opening device

Technical Field

The utility model relates to an injection mold field especially relates to mold opening devices.

Background

The turnover box mold structure is used for producing plastic turnover boxes through injection molding, and the turnover boxes are used for transporting and storing products.

The existing turnover box mold structure is directly acted on the sliding block through external force when a product is molded and opened, the mold is opened after the sliding block is pulled open, the acting force is uneven, the quality problem that the product is napped and broken is easily caused, the production efficiency is low, and the rejection rate is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing mold opening devices.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

mold opening devices comprise a fixed mold, four sliding blocks and a movable mold, wherein the fixed mold is connected with the movable mold through guide pillars, the sliding blocks are arranged between the fixed mold and the movable mold, the sliding blocks are in sliding fit with the fixed mold through inclined guide pillars, the four sliding blocks are connected with each other through guide connecting blocks, and the mold opening devices are characterized in that drag hooks for opening and closing molds are arranged on the movable mold, and pull buckles matched with the drag hooks are arranged on the sliding blocks.

The two sides of the movable die are provided with drag hooks for opening and closing the die, and the two sides of the sliding block are also provided with pull buckles matched with the drag hooks.

The tail end of the drag hook is fixedly connected with the movable mould through a dovetail groove on the movable mould.

The pull buckle is type, the draw hook is inserted into the type frame of the pull buckle, and the top end part of the draw hook is provided with a inclined plane.

Each sliding block is in sliding fit with the fixed die through two inclined guide pillars.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an install the drag hook on the movable mould, during the pulling movable mould, through the drag hook hookup draw knot, the slider is under the drive of drawing the knot, slowly open and then drag hook moving direction removes along oblique guide pillar, to opening required position after, the drag hook continues the motion, the drag hook with draw the knot and throw off, the die sinking is accomplished, such die sinking mode can avoid the inhomogeneous problem of effort effectively, the die sinking is convenient and the product yield is high, can not only the efficient accomplish the drawing of patterns, and can not draw bad and draw the hair product, in its actual production, the yield is very high.

FIG. 2 is a schematic structural view of the middle section of the mold opening of the present invention;

fig. 3 is a schematic structural diagram of the present invention when the mold opening is completed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments, not all embodiments, of the present invention .

Referring to fig. 1-3, mold opening devices comprise a fixed mold 1, a slide block 2 and a movable mold 3, wherein the fixed mold 1 is connected with the movable mold 3 through a guide pillar 4, the slide block 2 is arranged between the fixed mold 1 and the movable mold 3, the slide block 2 is in sliding fit with the fixed mold 1 through an inclined guide pillar 7, the slide block 2 is four, and adjacent slide blocks 2 are connected through a guide connecting block 8.

The two sides of the movable die 3 are provided with drag hooks 5 for opening and closing the die, and the two sides of the sliding block 2 are also provided with pull buckles 6 matched with the drag hooks 5. The draw hook 5 and the draw buckle 6 on the two sides are matched, so that the tension of the sliding block 2 can be better ensured, and the purpose of uniform pulling is achieved.

The tail end of the drag hook 5 is fixedly connected with the movable mould through a dovetail groove 3-1 on the movable mould 3. The size of the die is reduced, and the die is convenient to disassemble and assemble.

The pull buckle 6 is type, the draw hook 5 is inserted in a type frame of the pull buckle 6, and the top end part of the draw hook 5 is provided with a inclined plane, so that the draw hook 5 and the pull buckle 6 can be conveniently separated when the drawing is in place.

Each sliding block 2 is in sliding fit with the fixed die 1 through two inclined guide pillars 7. Connect firmly, the direction is accurate, can also guarantee the effect of its die sinking compound die simultaneously.

It should be noted that the utility model discloses the standard part that uses all can purchase from the market, and dysmorphism piece can all be customized according to the record of description and attached drawing, and the concrete connected mode of each part all adopts conventional means such as mature bolt, rivet, welding among the prior art, and machinery, part and equipment all adopt among the prior art, conventional model, and the inventor does not detailed herein again.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
