Description

A kind of encapsulation die

Technical field

The utility model relates to a kind of encapsulation die, belongs to mould applications.

Background technology

Encapsulate is a kind of secondary forming process, refers to that thermoplastic elastomer (TPE) is adhesively bonded to a kind of injection moulding process of engineering plastic by melting.Briefly, be exactly a first shaping plastic product, then this product be put into another plastic cement of injection moulding in other one set of die, thus become the technique that one has the product of two kinds of plastic cement.The shell of electric drill as shown in Figure 1, outer cover body K1 is plastic part, and K2 is plastic cement product, for this complex-shaped plastic, needs lifter demoulding mechanism to carry out the demoulding.Taper pin in tradition mould emptier is all-in-one-piece, and taper pin extends in push pedal, mutually may intersect, interferes with each other between taper pin.In addition, because taper pin is comparatively elongated, its less stable.

Utility model content

For solving the problems of the technologies described above, the utility model object is a kind of encapsulation die, and its mould emptier can not interfere phenomenon, and stability is better.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of encapsulation die, comprise fixed half and moving half, described cover half comprises solid plate, fixed mold core and cover half inner core, described fixed mold core is fixed on the lower end of described solid plate, described cover half inner core is fixed in described fixed mold core, and described dynamic model comprises moving platen, mavable module core and ejecting mechanism, and described mavable module core is fixed on the upper end of described moving platen, described ejecting mechanism is positioned at the below of described moving platen

Described ejecting mechanism comprises supporting plate, push pedal, taper pin and push rod, described taper pin is through described dynamic model inner core, and its bottom is fixed on described push rod, the bottom of described push rod is vertically inserted in described push pedal, and the bottom face of described push rod is fixed on a fixed block, described fixed block is installed in described supporting plate.

Preferably, the head of described push rod offers the groove that is inverted T shape, and the bottom of described taper pin forms the projection with the inverted T shape of described groove match.

By technique scheme, the encapsulation die that the utility model provides, is provided with push rod by the bottom at taper pin, so shortens the length of taper pin, improves its stability, can also prevent from intersecting between taper pin with taper pin, interfering.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below the required accompanying drawing used in describing embodiment or in prior art is briefly described.

Fig. 1 is the structural representation of the shell of the electric drill disclosed in the utility model embodiment;

Fig. 2 is the front sectional view of a kind of encapsulation die disclosed in the utility model embodiment;

Fig. 3 is the structural representation of a kind of ejecting mechanism disclosed in the utility model embodiment;

Fig. 4 is the disassembly diagram of a kind of ejecting mechanism disclosed in the utility model embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Shown in Fig. 2-4, the utility model provides a kind of encapsulation die, comprises fixed half and moving half,

Cover half comprises solid plate B1, fixed mold core B2 and cover half inner core B3, and fixed mold core B2 is fixed on the lower end of solid plate B1, and cover half inner core B3 is fixed in fixed mold core B2,

Dynamic model comprises moving platen C1, mavable module core C2 and ejecting mechanism, and mavable module core C2 is fixed on the upper end of moving platen C1, and ejecting mechanism is positioned at the below of moving platen C1,

Ejecting mechanism comprises supporting plate D1, push pedal D2, taper pin D3 and push rod D4, taper pin D3 is through dynamic model inner core C3, and its bottom is fixed on push rod D4, the bottom of push rod D4 is vertically inserted in push pedal D2, and the bottom face of push rod D4 is fixed on a fixed block D5, fixed block D5 is installed in supporting plate D1.

Shown in Fig. 3-4, the head of push rod D4 offers the groove D41 that is inverted T shape, and the bottom of taper pin D3 forms the projection D31 of the inverted T shape matched with groove D41.Push rod D4 and taper pin D3 realizes fixing by the grafting of groove D41 and projection D31.

After die sinking, dynamic model retreats, and push pedal D2 is up, and taper pin D3 also can move upward, and ejected from dynamic model inner core C3 by product, product falls under gravity subsequently.

By technique scheme, the encapsulation die that the utility model provides, by being provided with push rod D4 in the bottom of taper pin D3, so shortening the length of taper pin, improve its stability, can also prevent from intersecting between taper pin with taper pin, interfering.

To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
