Abstract
The utility model discloses a spure spreader with an improved structure, which comprises a spure spreader body, the bottom of which is fixedly connected with a moving die, and the top of which is provided with a boss; and the boss respectively inclines downwards and smoothly extends for transition towards the outer sides at the two ends to form a left circular arc concave surface and a right circular arc concave surface. Compared with the prior art, the spure spreader with the improved structure has the benefits of being simple in structure, strong in universality and good in effect, greatly improving the phenomenon of being thick or thin at times when in die-casting molding, ensuring a casting piece which especially has a deep cavity and is complicated to be easily molded and have good quality, and better saving the material used for a sprue.
Description
Technical field
The utility model relates to a kind of minute flow cone, belongs to the running gate system mechanical equipment technical field, refers in particular to a kind of branch flow cone that improves structure.
Background technology
The running gate system of die casting is the passage of molten metal at the effect retrofilling mold cavity of pressure, and it partly is made up of sprue, cross gate, ingate and clout etc.Sprue is general main to be become by sprue bush, shunting taper, divides the structure of flow cone can take sprue out of, connects cross gate simultaneously, plays in running gate system than important function, and its effect mainly shows as: 1, shunting supercharging, be convenient to foundry goods compacting, densification; 2, stablize materials flow, make quick, the evenly filling of metal liquid; 3, reduce metal liquid erosion to forming surface when filling; 4, reduce the materials of cast gate; 5, make cast gate stay dynamic model on one side, be convenient to drag mould.As shown in Figure 1, traditional branch flow cone, dividing the top of flow cone body 1 generally is a round platform, when the molten metal of nozzle ejection passes through sprue, when impacting round platform, often because the whole Da Yi of impact produces the gap of circling round, thereby make pressure inhomogeneous, cause molten metal to fill when occurring behind the mold cavity forming phenomenon thin when thick, especially for dark chamber, complicated foundry goods, divide flow cone to play the effect that can not lack, and the quality of its design have very big influence to quality.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, provide a kind of simple and reasonable, shunting pressurized effect obviously, practical and reliable improves the branch flow cone of structure.
To achieve these goals, the utility model is realized by following technical scheme:
A kind of branch flow cone that improves structure, include branch flow cone body, fixedly connected with dynamic model in the bottom of described minute flow cone body, the top of described minute flow cone body is provided with a boss, and boss is tilted to down smooth extension transition respectively to the outside, two ends and forms left circular arc concave surface and right circular arc concave surface.
Further, be provided with cooling water chamber, water inlet pipe and outlet pipe in the flow cone body in described minute; Wherein, be equiped with the copper pipe of an end opening in the described cooling water chamber, water inlet pipe is communicated with copper pipe, and outlet pipe is communicated with cooling water chamber, and described cooling water chamber, copper pipe and inlet tube and outlet tube form circulation cooling closed system.
Further, described boss is provided with a feed chute, is provided with thimble structure in the feed chute.
Further, the corner of described boss and circular arc concave surface is set to smooth fillet, and it is poor that boss top and circular arc concave bottom have certain height.
Further, the smooth fillet of described boss is R15～R20, with the difference in height of circular arc concave bottom be 20mm～30mm.
The utility model compared with prior art, its beneficial effect is:
1, the utility model is after the original platform position of existing branch flow cone processes a false boss, molten metal runs into boss can be divided into two strands, boss and step position form a ftercompction, increase pressure, make easier, the better quality of moulding of the particularly dark chamber of foundry goods, complexity;
2, after the utility model increases false boss, the contact area of the molten metal and the conical surface is because of many areas of boss both sides, make contact area bigger, mobile better, reduce molten metal and impacted the gap that the conical surface produced, make flow velocity more be tending towards evenly, stable, thin phenomenon when thick when having improved die cast greatly.
3, the utility model has increased pressure because of having used false boss, has improved flowability, thereby can more save the materials of cast gate.
4, the utility model is after increasing false boss, and the moulding at foundry goods cast gate place presses more in fact, closeer, significantly reduced interlayer, can not collapse so easily when knocking out cast gate simultaneously to lack deeply.
5, the utility model has increased pressure, has improved flowability after increasing false boss, makes the easier discharge of slag gas at remote position, dark chamber, and pore still less.
6, the utility model is simple in structure, and highly versatile is effective.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the backsight structural representation of Fig. 2.
Fig. 4 is the structure cutaway view of Fig. 2.
The specific embodiment
Shown in Fig. 2～4, the branch flow cone of improvement structure described in the utility model, include branch flow cone body 1, fixedly connected with dynamic model by screw in the bottom of described minute flow cone body 1, the top is provided with a boss 2, and boss 2 is tilted to down smooth extension transition respectively to the outside, two ends and forms left circular arc concave surface 31 and right circular arc concave surface 32.
Be provided with cooling water chamber 41, water inlet pipe 42 and outlet pipe 43 in the above-mentioned minute flow cone body 1; Wherein, be equiped with the copper pipe 44 of an end opening in the described cooling water chamber 41, water inlet pipe 42 is communicated with copper pipe 44, and outlet pipe 43 is communicated with cooling water chamber 41, and described cooling water chamber 41, copper pipe 44 and inlet tube and outlet tube 42,43 form circulation cooling closed system.
Further, described boss 1 is provided with a feed chute, is provided with thimble structure in the feed chute.
Further, described boss 1 is set to smooth fillet with the corner of circular arc concave surface 31,32, and it is poor that boss 1 top and circular arc concave surface 31,32 bottoms have certain height.There is certain fillet at boss 2 edges, and boss 2 is bigger with the transition arc of circular arc concave surface 31,32, make when molten metal touches the branch flow cone, and are slick and sly smooth and easy, mobile relatively good; Boss 2 tops have certain height poor to circular arc concave surface 31,32 bottoms, and when boss 2 is divided into two strands to molten metal, three contact points on the Different Plane can carry out certain ftercompction, compensation molten metal gap, simultaneously can coordinate flow velocity, make speed be tending towards evenly balance.
