Description
Technical field
The utility model belongs to mould manufacturing field, especially a kind of cold burden buffer structure of die casting.
Background technology
Die casting is a kind of method of casting liquid forging, a kind of technique completed on special die casting die forging machine.Its basic craft course is: the first low speed of molten metal or high-speed casting fill in the die cavity of type progressive die tool, mould has movable cavity surface, it, along with the cooling procedure pressurization forging of molten metal, had both been eliminated the shrinkage porosity defect of contraction cavity of foundry goods, and had also made the interior tissue of foundry goods reach the Broken Crystal of forging state.
The uneven problem of material feeding is often there is in traditional Design of Die, by analysis, the main cause of the problems referred to above is caused to be: because the molten metal just injecting mould often flows into mold cavity edge, and the molten metal temperature injecting mould is at first low, poor fluidity, cause molten metal not easy-formation, affect the quality of foundry goods, the defective work of production is many.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the cold burden buffer structure of the die casting that a kind of structure is simple, design science is reasonable, yield rate is high.
Scheme of the present utility model is achieved in that
A cold burden buffer structure for die casting, comprises lower bolster, lower mold core, cope match-plate pattern and upper mold core, the middle part setting-in lower mold core of described lower bolster, and this lower mold core is shaped with the lower impressions of circular configuration, and the lower bolster of this lower mold core side is shaped with lower charging aperture; The middle part setting-in upper mold core of described cope match-plate pattern, this upper mold core is shaped with upper impression, the cope match-plate pattern of this upper mold core side is shaped with the upper feeding mouth coordinated with described lower charging aperture, this cope match-plate pattern four corner is fixedly mounted with four locating dowels coordinated with lower bolster, cold burden buffer board under the symmetrical setting-in in the upper and lower two sides of described lower bolster, this lower cold burden buffer board is communicated with lower impressions by runner; The upper and lower two sides of described cope match-plate pattern are embedded with the upper cold burden buffer board coordinated with described lower cold burden buffer board.
And described lower cold burden buffer board end face parallel interval is evenly shaped with multiple lower rectangular preiection, and described upper cold burden buffer board end face is shaped with the upper rectangular recess coordinated with described lower rectangular preiection.
And described runner is bending rotary type structure.
Advantage of the present utility model and good effect are:
1, in this mould, cold burden buffer board is installed, this cold burden buffer board can make to flow in mould at first and the waste material molten metal that temperature is low flows in two cold burden buffer boards, ensure that the molten metal temperature entered in die cavity is consistent and flowing is even, ensure that the quality of foundry goods.
2, the cold burden buffer board in this mould is shaped with the multiple rectangular recess evenly arranged, and makes molten metal flow velocity even, effectively improves casting quality.
3, the utility model structure is simple, design science reasonable, and easy-formation, effectively improves the quality of foundry goods.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model counterdie;
Fig. 2 is the perspective view of the utility model patrix;
Fig. 3 is the I portion enlarged drawing in Fig. 1;
Fig. 4 is the II portion enlarged drawing in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of cold burden buffer structure of die casting, as shown in Figure 1 and Figure 2, comprise lower bolster 1, lower mold core 2, cope match-plate pattern 7 and upper mold core 8, the middle part setting-in lower mold core of described lower bolster, this lower mold core is shaped with the lower impressions 2A of circular configuration, and the lower bolster of this lower mold core side is shaped with lower charging aperture 3; The middle part setting-in upper mold core of described cope match-plate pattern, this upper mold core is shaped with upper impression 8A, and the cope match-plate pattern of this upper mold core side is shaped with the upper feeding mouth 12 coordinated with described lower charging aperture, and this cope match-plate pattern four corner is fixedly mounted with four locating dowels 9 coordinated with lower bolster.
Innovative point of the present utility model is:
1, cold burden buffer board 5 under the symmetrical setting-in in the upper and lower two sides of described lower bolster, this lower cold burden buffer board is communicated with lower impressions by runner 4, and described lower cold burden buffer board end face parallel interval is evenly shaped with multiple lower rectangular preiection 6, as shown in Figure 3.
The upper and lower two sides of described cope match-plate pattern are embedded with the upper cold burden buffer board 10 coordinated with described lower cold burden buffer board, and on this, cold burden buffer board end face is shaped with the upper rectangular recess 11 coordinated with described lower rectangular preiection, as shown in Figure 4.
When casting of molten metal, at first in inflow mould and the waste material molten metal that temperature is low flows in two cold burden buffer boards, ensure that the molten metal temperature entered in die cavity is consistent and flowing is even, ensure that the quality of foundry goods.
2, described runner is bending rotary type (i.e. S type) structural design, and this runner plays the effect of buffering, ensures, in molten metal Uniform Flow die cavity, to improve casting quality.
The beneficial effects of the utility model are:
1, in this mould, cold burden buffer board is installed, this cold burden buffer board can make to flow in mould at first and the waste material molten metal that temperature is low flows in two cold burden buffer boards, ensure that the molten metal temperature entered in die cavity is consistent and flowing is even, ensure that the quality of foundry goods.
2, the cold burden buffer board in this mould is shaped with the multiple rectangular recess evenly arranged, and makes molten metal flow velocity even, effectively improves casting quality.
3, the utility model structure is simple, design science reasonable, and easy-formation, effectively improves the quality of foundry goods.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
