Abstract
The invention discloses a gravity casting pouring gate structure of a bent zinc alloy casting. The gravity casting pouring gate structure comprises a die body with a die cavity bent into an arc shape, a chord formed by connecting both ends of the arc faces upward, and the arc faces downward; a suspended sand core with the shape matched with the die cavity is arranged inside the die cavity, and a forming wall cavity is formed inside a space between the sand core and the die cavity wall; and the die body also comprises an inlet pouring channel and an outlet pouring channel, and the two are respectively communicated with both ends of the forming wall cavity. In the invention, the inlet pouring channel and the outlet pouring channel are respectively communicated with both ends of the forming wall cavity, the impact of injected zinc alloy on the sand core is reduced, the problems of non-uniform casting wall thickness, casting foaming and slag inclusion due to sand core displacement caused by too large impact are avoided, the zinc alloy liquid poured through the inlet pouring channel can quickly flow from one end to the other end and finally flows to the outlet pouring channel, the liquid injection speed is high, and no dead corner or turbulence occurs. The gravity casting pouring gate structure can be widely applied to gravity casting bent zinc alloy parts.
Description
Technical field
The present invention relates to a kind of pouring gate structure of casting mould, particularly the pouring gate structure of the casting mould of kirsite gravitational casting.
Background technology
So-called gravitational casting refers to that molten metal injects the technology of casting mold under the terrestrial gravitation effect, also claims casting, and this metal casting technique is widely used in the zinc alloy casting field with its advantage simple in structure, with low cost.Even zinc alloy piece some bendings, that have inner chamber, its rough casting also are to adopt gravitational casting.With reference to Fig. 1, the Zinc alloy casting gravitational casting pouring gate structure of conventional bending, comprise die ontology, dig a die cavity that bends to arc in the die ontology, the string that this arc two ends line constitutes up, arc down, be equipped with the core 2 of unsettled, shape and die cavity coupling in the die cavity, space between core 2 and die cavity wall constitutes forming wall chamber 1, also process downward main running channel 7 in the die ontology, main running channel 7 stretches downwards and is branched off into some roads and divides running channel 8, divides running channel 8 also to be positioned at the crooked camber line envelope scope in forming wall chamber 1, finally is communicated with forming wall chamber 1.Such pouring gate structure design, be the zinc alloy metal liquid that pours into fusion for convenience from vertical direction downwards from main running channel 7, molten metal is through undue running channel 8 bifurcateds, reduce impact stress, when they after minute running channel 8 enters into forming wall chamber 1, be filled to whole forming wall chamber 1 rapidly, cooling then, final shape moulding according to forming wall chamber 1.Yet, are the sides that are communicated to forming wall chamber 1 owing to divide running channel 8, the impulsive force that molten metal injects is still bigger, core 2 is impacted become flexible easily, produces dislocation, and the wall unevenness of the crooked foundry goods of producing like this is even; Thisly in addition be easy to generate turbulent flow from the pouring type of side in the middle of being flushed to, easily wrap up in gas and be mingled with, material slag difficult treatment.
Summary of the invention
Purpose of the present invention, when being to provide a kind of cast zinc liquid, core is difficult for the crooked Zinc alloy casting gravitational casting pouring gate structure of displacement.
The solution that the present invention solves its technical problem is:
Crooked Zinc alloy casting gravitational casting pouring gate structure, comprise and dig a die ontology that bends to the die cavity of arc, the string that described arc two ends line constitutes up, arc down, be equipped with the core of unsettled, shape and die cavity coupling in the die cavity, space between core and die cavity wall constitutes the forming wall chamber, and described die ontology also includes running channel and goes out running channel, and the two is communicated with the two ends in forming wall chamber respectively.
As further improvement in the technical proposal, describedly go into running channel, go out the position that running channel is communicated with the two ends in forming wall chamber respectively, be provided with surge chamber.
The invention has the beneficial effects as follows: the present invention has changed the link position in running channel and forming wall chamber, allow into running channel with go out running channel and be communicated with the two ends in forming wall chamber respectively, just can directly not impact core side the die cavity from going into zinc liquid that running channel pours into so, cause displacement, only can impact the end face of core, shock surface is little, significantly reduced impulsive force, avoided excessive impact to make the core displacement make casting section thickness inconsistent, foundry goods bubbles, slag inclusion, can be filled to the other end rapidly from one from going into the zinc liquid that running channel pours into, flow to out at last running channel, fluid injection speed is fast, no dead angle, turbulent flow.Simple and ingenious structure of the present invention can be widely used in the zinc alloy piece of gravitational casting bending.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing and example.
Fig. 1 is traditional crooked Zinc alloy casting gravitational casting pouring gate structure;
Fig. 2 is structure principle chart of the present invention.
The specific embodiment
With reference to Fig. 2, crooked Zinc alloy casting gravitational casting pouring gate structure, comprise and dig a die ontology that bends to the die cavity of arc, the string that described arc two ends line constitutes up, arc is equipped with the core 2 of unsettled, shape and die cavity coupling, the formation forming wall chamber, space 1 between core 2 and die cavity wall down in the die cavity, described die ontology also includes running channel 4 and goes out running channel 5, and the two is communicated with the two ends in forming wall chamber 1 respectively.
Be further used as preferred embodiment, describedly go into running channel 4, go out the position that running channel 5 is communicated with the two ends in forming wall chamber 1 respectively, be provided with surge chamber 6.Surge chamber 6 can be avoided direct impact effectively, further reduces impulsive force.
In addition, this laminar flow fluid injection mode from the end face fluid injection has been avoided the turbulent phenomenon of side fluid injection, and air is to drain to the other end from an end, and exhaust is smooth and easy complete, and bubbling in no dead angle, can effectively solve to impact core 2, wraps up in problems such as gas.Through experiment, the yields of producing before improving is 50%, and the yields of the present invention after the improvement is 85%.
In addition, the present invention can also carry out following preferred embodiment:
Be further used as preferred embodiment, described die ontology is steel alloy, and the running channel position is edge copper, and such material structure distributes, and helps and the poor thermal conduction alienation, is beneficial to integral heat insulation and local heat radiation.
Be further used as preferred embodiment, described die cavity inwall is close to and is had one deck complex layer coating layer.By changing the composition of complex layer coating in the complex layer coating layer, allow it have heat conduction or adiabatic effect, its position and thickness are adjustable, and thickness can be between 150～250 microns.
More than be that preferred embodiments of the present invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of spirit of the present invention, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
