Abstract

The utility model provides a bidirectional separating and sliding demolding mechanism of an injection mold concave die. The bidirectional separating and sliding demolding mechanism comprises a convex die, a left concave die, a right concave die and a die bottom plate, wherein the left concave die and the right concave die are symmetrically arranged on the die bottom plate on the left side and the right side; the convex die is positioned above a joint part between the left concave die and the right concave die; the bidirectional separating and sliding demolding mechanism further comprises a plurality of inclined guide rods, and a plurality of springs; lower ends of the inclined guide rods penetrate through the left concave die and the right concave die obliquely and then arranged in the die bottom plate; the plurality of springs are arranged on the upper surface of the die bottom plate; a plurality of deep grooves are formed below the left concave die and the right concave die; the plurality of springs are vertically and respectively arranged in the plurality of deep grooves; the plurality of springs are used to push the left concave die and the right concave die to slide upwards along the inclined guide rods. With thrust of the springs, the left concave die and the right concave die are driven to slide upwards along the inclined guide rods, so that the demolding operation can be conveniently and quickly realized.

Description

The two-way separation slip of injection mold die mould emptier

Technical field

The utility model injection mold technical field, the particularly two-way separation slip of a kind of injection mold die mould emptier.

Background technology

All kinds of plastic cement products are substantially all that mold injection forms, and the good and bad direct relation of the performance of injection mold the product quality, production technology, production cost of plastic cement products etc.At present, in order to improve the structural strength of injecting products, injecting products outer surface is often provided with zanjon reinforcement, for existing injection mold, adopts common stripping means demoulding difficulty.

Summary of the invention

The purpose of this utility model is to provide the two-way separation slip of a kind of injection mold die mould emptier, to solve the problem of demoulding difficulty in the time that production outer surface is provided with the injecting products of zanjon reinforcement at present.

To achieve these goals, the technical solution of the utility model is as follows:

The two-way separation slip of a kind of injection mold die mould emptier, comprise punch, left die, right die and die bottom plate, described left die, right die are located on described die bottom plate and are symmetrical set, described punch is positioned at the top of described left die, right die joint portion, wherein, also comprise: many Angle Pins, lower end is respectively obliquely through being located in described die bottom plate after described left die, right die; Multiple springs, at described die bottom plate upper surface, the below of described left die, right die is provided with multiple deep trouths, and described multiple springs are located at respectively in described multiple deep trouth vertically, and described multiple springs are used for promoting described left die, right die along described Angle Pin upward sliding.

Preferably, in the two-way separation slip of described injection mold die mould emptier, described Angle Pin is four, and wherein two described Angle Pins are through described left die, and another two described Angle Pins are through described right die.

Preferably, in the two-way separation slip of described injection mold die mould emptier, described spring is two, lays respectively at the below of described left die, right die.

Analyze knownly, the utility model utilizes the thrust of spring to drive left die, right die along Angle Pin upward sliding, can realize very convenient, fast stripping operation.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model preferred embodiment.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

As shown in Figure 1, the utility model preferred embodiment comprises punch F, left die A, right die B, Angle Pin D, die bottom plate C, spring E.

Particularly, left die A, right die B are located at die bottom plate C and go up and be symmetrical set, punch F is positioned at the top of left die A, right die B joint portion, and the lower end of many Angle Pin D is located in die bottom plate C through after left die A, right die B respectively obliquely.Multiple spring E are at die bottom plate C upper surface, and the below of left die A, right die B is provided with multiple deep trouth CE, and multiple spring E are located at respectively in multiple deep trouth CE vertically, and multiple spring E are used for promoting left die A, right die B along Angle Pin D upward sliding.

Preferably, Angle Pin D is four, and wherein two Angle Pin D are through left die A, and another two Angle Pin D are through right die B.Spring E is two, lays respectively at the below of left die A, right die B.

When application, four Angle Pin D are fixed on die bottom plate C above, and it is upper that left die A and right die B are arranged on Angle Pin D, on Angle Pin D, can slide up and down.Spring E is fixed on the deep trouth CE Inner of die bottom plate C.When matched moulds, left die A and right die B overcome the elastic force of spring E under the promotion of punch F, and along Angle Pin, D moves reset, completes mould assembling action.After injection moulding completes, punch F retreats, and left die A and right die B are under the thrust of spring E, and along Angle Pin, D moves up, and left die A, right die B move outward, completes demoulding action, and product ejects, and completes injection moulding.

To sum up, stripping operation of the present utility model is very convenient, and instant injecting products outer surface is provided with zanjon reinforcement, and due to the thrust of spring, after injection moulding completes, stripping operation is also very quick.

As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.Allly within the scope of the utility model or in the change being equal in scope of the present utility model, be all included in the utility model.
