Description
Technical field
The utility model relates to technical field of mold, more particularly, particularly a kind of for the precision casting mfg. moulding die in high service system.
Background technology
As shown in Figure 1, for the parts in high service system, mainly play the effect that bend pipe connects, generally die casting and molding is adopted in prior art, but the shortcoming that prior art exists is: owing to not discharged by gas timely in die casting and molding process, easily in foundry goods, form pore, have impact on the quality of cast product.Therefore, be necessary to design a kind of new structure for the precision casting mfg. moulding die in high service system.
Utility model content
The purpose of this utility model is to provide a kind of avoids pore to produce, improve casting product quality for the precision casting mfg. moulding die in high service system.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of for the precision casting mfg. moulding die in high service system, comprise the top mold frame being provided with upper cavity and the lower mold holder being provided with lower mode cavity, described upper cavity and lower mode cavity match, it also comprises an air vent device, described air vent device comprises the upper pore being located at top mold frame side, be located at lower mold holder side and the air holes matched with upper pore, the valve matched with upper pore and air holes.
Preferably, described upper pore is identical with the structure of air holes, for half cylindrical structure and outside are pyramidal structure inside being all.
Preferably, also comprise the positioner be located between top mold frame and lower mold holder, described positioner comprises the multiple locating pieces being located at top mold frame lower end, and is located at multiple locating slots of lower mold holder upper end, and described locating piece and locating slot match.
Preferably, described locating piece and locating slot are three, and wherein, three locating pieces lay respectively at three corners of top mold frame lower end, and three locating slots lay respectively at three corners of lower mold holder upper end.
Compared with prior art, the utility model has the advantage of: the utility model, by being provided with air vent device in top mold frame between lower mold holder, can making the gas of foundry goods in casting process discharge, avoid on foundry goods and produce pore, improve the product quality of foundry goods.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation for the precision casting in high service system described in the utility model.
Fig. 2 is the structural representation for top mold frame in the precision casting mfg. moulding die in high service system described in the utility model.
Fig. 3 is the structural representation for lower mold holder in the precision casting mfg. moulding die in high service system described in the utility model.
Description of reference numerals: 1, top mold frame, 2, locating piece, 3, upper pore, 4, valve, 5, upper cavity, 6, lower mold holder, 7, locating slot, 8, lower mode cavity, 9, air holes.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 2 and Fig. 3, the utility model provides a kind of for the precision casting mfg. moulding die in high service system, comprise the top mold frame 1 being provided with upper cavity 5 and the lower mold holder 6 being provided with lower mode cavity 8, described upper cavity 5 matches with lower mode cavity 8, it also comprises an air vent device, described air vent device comprises the upper pore 3 being located at top mold frame 1 side, is located at lower mold holder 6 side and the air holes 9 matched with upper pore 3, the valve 4 matched with upper pore 3 and air holes 9.
In the utility model, described upper pore 3 is identical with the structure of air holes 9, is all inner sides for half cylindrical structure and outside are pyramidal structure, and such structure is convenient to the processing of pore 3 and air holes 9 and is coordinated, and is also convenient to the installation of valve 4.
As preferably, generally in upper pore 3 with the half cylindrical structure of air holes 9, be provided with internal thread, valve 4 is provided with external screw thread, when casting, valve 4 can be taken out with easy to exhaust, and when not casting, valve 4 can be installed and enter in upper cavity 5 or lower mode cavity 8 to avoid extraneous impurity.Therefore, valve 4 can play two effects, and the effect can played venting on the one hand and avoid impurity to enter, can play the effect connecting top mold frame 1 and lower mold holder 6 on the other hand.
In order to avoid producing slippage when casting between top mold frame 1 and lower mold holder 6, the utility model also comprises the positioner be located between top mold frame 1 and lower mold holder 6, described positioner comprises the multiple locating pieces 2 being located at top mold frame 1 lower end, and be located at multiple locating slots 7 of lower mold holder 6 upper end, described locating piece 2 matches with locating slot 7.
As preferably, the locating piece 2 described in the present embodiment and locating slot 7 are three, and wherein, three locating pieces 2 lay respectively at three corners of top mold frame 1 lower end, and three locating slots 7 lay respectively at three corners of lower mold holder 6 upper end.
Although describe embodiment of the present utility model by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present utility model, all should within protection domain of the present utility model.
