Technical field

The utility model relates to a kind of shaped device, relates in particular to a kind of inner chamber shaped device of model casting pipe fitting product.

Background technology

In model casting is produced, produce the wax part operation that is absolutely necessary, and in the prior art, the production of pipe fitting is all to utilize two molds to coordinate to produce wax parts conventionally.Utilize two molds to coordinate and produce wax part, operation is various, and production efficiency is low, to staff, brings very large trouble.

Utility model content

The purpose of this utility model is exactly in order to address the above problem, and a kind of inner chamber shaped device of model casting pipe fitting product is provided, and it has advantages of enhances productivity.

To achieve these goals, the utility model adopts following technical scheme:

An inner chamber shaped device for pipe fitting product, it comprises upper die and lower die, upper die and lower die are respectively equipped with upper impression, lower impressions; During matched moulds, upper impression and lower impressions form complete die cavity; On described counterdie, be also provided with Jin La Dao，Jin La road and be communicated with lower impressions, described plug I and plug II successively insert in adapter sleeve, and close contact, place it in die cavity simultaneously, and described patrix is buckled on counterdie.

Described adapter sleeve is rubber sleeve.

The beneficial effects of the utility model: the utility model is simple in structure, easy to use, the wax part qualification rate of production is high, enhances productivity.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is plug connection layout of the present utility model;

Fig. 3 is the wax part schematic diagram that the utility model is produced.

Wherein, 1. plug I, 2. counterdie, 3. rubber sleeve ，4.Jin La road, 5. die cavity, 6. plug II, 7. wax part.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a kind of inner chamber shaped device of model casting pipe fitting product, it comprises upper die and lower die 2, upper die and lower die are respectively equipped with upper impression, lower impressions; During matched moulds, the upper lower impressions of upper and lower mould forms complete die cavity 5.On described counterdie 2, being also provided with 4 ，Jin La roads 4, Jin La road is communicated with lower impressions; Plug I1 and plug II6 utilize rubber sleeve 3 to link together, and are placed in die cavity 5, and described patrix is buckled on counterdie 2.

During use, utilize rubber sleeve 3 that plug I1 and plug II6 are linked together, and it is closely seamless to guarantee that they contact, and the plug I1 connecting and plug II6 are placed on counterdie 2, patrix closes, utilization is penetrated wax machine and is penetrated wax by Jin La road 4, penetrate after wax, open patrix, extract plug I1 and plug II6 out, wax part is taken out from counterdie 2, obtain wax part 7 as shown in Figure 3; Utilize the pliability of rubber sleeve 3, it is taken out from wax part 7 inner chambers, remaining be needed wax part 7.

Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
