Abstract
The utility model relates to a mould shell precisely cast by a lost-wax process, belonging to the technical field of metal casting mould shells; the mould shell precisely cast by the lost-wax process comprises a mould shell main body; the top of the mould shell main body is provided with a casting head; the mould shell main body is internally provided with a die cavity; the die cavity is communicated with the casting head by a pouring gate; the mould shell precisely cast by the lost-wax process is characterized in that the mould shell main body is externally provided with a hollow circulating pouring gate; and one end of the circulating pouring gate is communicated with the die cavity, and the other end of the circulating pouring gate is communicated with the casting head. The circulating pouring gate is added into the mould shell, so that the air is guaranteed not to pass through the same pouring gate together with metallic solution when being discharged, the metallic solution flows rapidly and is fully filled in the die cavity, and the casting flaws can be reduced.
Description
Technical field
The utility model relates to metal casting formwork technical field, is specifically related to a kind of lost-wax process precise casting mould shell.
Background technology
During lost-wax process hot investment casting casting, metallic solution generally enters die cavity by dead head along running channel, makes metallic solution be full of whole die cavity, and reaches the purpose of making carcass.Air in when casting die cavity is also discharged by dead head along running channel, because metallic solution all is by same running channel motion with air, so there is the mobile casting defect such as bubble that freely, easily do not produce of metallic solution.
The utility model content
Technical problem to be solved in the utility model is to improve a kind of to solve existing formwork casting, particularly large metal formwork, exist metallic solution flow smooth, Bas Discharged is inconvenient and easily produce the lost-wax process precise casting mould shell of casting defect problem.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of lost-wax process precise casting mould shell, comprise a formwork main body, described formwork main body top is provided with dead head, be provided with die cavity in the described formwork main body, described die cavity is communicated with dead head by running channel, it is characterized in that: the outside of described formwork main body is provided with the circulation running channel of interior sky, and described circulation running channel one end is communicated with die cavity, and the circulation running channel other end is communicated with dead head.
Described circulation running channel one end is near edge on the dead head, and the other end is positioned at the die cavity bottom.
Described circulation running channel is provided with one at least.
Described circulation running channel adopts the wax bar to make.
The beneficial effects of the utility model are: the utility model has increased the circulation running channel, has so just guaranteed that air do not walk the same running channel with metallic solution in discharge process, guaranteed metallic solution rapid flow, be full of die cavity, reduce the generation of casting flaw.
Description of drawings
Fig. 1 is the utility model embodiment stereogram;
Fig. 2 is the utility model embodiment profile.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, to make the vase formwork as example, at the top 1/3-1/4 place of the upper edge of vase dead head 1 (generally being in the base position of vase) with vase, make circulation running channel 3 with the wax bar, after being stained with the oar hanging sand, form formwork.When casting metals solution, metallic solution at first flows into running channel 2 by dead head 1, progressively is full of whole die cavity 4, because the Action of Gravity Field of metallic solution, air in the die cavity can enter circulation running channel 3 fast, and enters dead head by circulation running channel 3, discharges formwork.So just guaranteed that air do not walk the same running channel with metallic solution in discharge process, guaranteed metallic solution rapid flow, be full of die cavity, reduce the generation of casting flaw.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (4)
1. lost-wax process precise casting mould shell, comprise a formwork main body, described formwork main body top is provided with dead head, be provided with die cavity in the described formwork main body, described die cavity is communicated with dead head by running channel, it is characterized in that: the outside of described formwork main body is provided with the circulation running channel of interior sky, and described circulation running channel one end is communicated with die cavity, and the circulation running channel other end is communicated with dead head.
