Technical field
The utility model belongs to mould manufacturing field, especially a kind of Novel pressure casting mould.
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 shortcoming of traditional moulds design is: 1, usually need to be carved with retrospective mark at the outer surface of foundry goods, because some casting structure is complicated, is difficult to a series of numeral or letter all to print in its surface.2, ejector beam generally designs the middle part at foundry goods, usually causes the foundry goods end face at ejector beam place to occur that multiple end is poor, affects the presentation quality of foundry goods.3, often there is the uneven problem of material feeding 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 Novel pressure casting mould that a kind of structure is simple, design science reasonable, appearance looks elegant, yield rate are high.
Scheme of the present utility model is achieved in that
A kind of Novel pressure casting mould, comprise 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, 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 the upper impression coordinated with lower impressions, 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, and the edge even circumferential of described lower impressions is shaped with multiple ejector beam;
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, and described lower cold burden buffer board end face parallel interval is evenly shaped with multiple lower rectangular preiection;
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 on this, cold burden buffer board end face is shaped with the upper rectangular recess coordinated with described lower rectangular preiection;
The multiple liftout mark rod of upper impression bottom surface setting-in of described upper feeding mouth side.
And described runner is bending rotary type structure.
Advantage of the present utility model and good effect are:
1, the ejector beam in this mould is arranged on the edge of lower impressions, avoids in the middle part of foundry goods and occurs holding poor problem because of the arranging unreasonable of ejector beam, effectively improve product appearance quality.
2, the little mark by being distributed in product surface diverse location in this mould can show its concrete date of manufacture, effectively ensure that product quality; And each liftout mark rod of fast changeable, makes simple to operate, be easy to realize.
3, 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.
4, 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.
5, the utility model structure is simple, design science reasonable, and easy-formation, effectively improves the quality of foundry goods.

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 Novel pressure casting mould, 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, the edge even circumferential of described lower impressions is shaped with multiple ejector beam 13, as shown in Figure 3, thus effectively can avoid occurring holding poor problem because of the arranging unreasonable of ejector beam in the middle part of foundry goods, effectively improve the presentation quality of product.
