Description
Technical field
The utility model relates to a kind of water tank of single cylinder diesel, relates in particular to a kind of single-cylinder water cooled diesel engine aluminium matter casting water tank.
Background technique
Cooling water tank is the indispensable parts of water-cooled diesel engine, because aluminum alloy material has good heat sinking function and decay resistance, therefore the preferential aluminium alloy material of single-cylinder water cooled diesel engine is made, existing single-cylinder water cooled diesel engine is all used aluminum alloy unit sand mould foundry technology, the wall thickness of this moulding by casting aluminum alloy water tank is big, the casting technique complexity, the materials consumption height, castability is difficult to guarantee, easily produce cold shut, shrinkage cavity shrinkage porosity, scab, the unequal defective of outer surface, be prone to the phenomenon of leaking, shatter during use.Simultaneously because the integral cast structure, the stiffening rib of water tank inboard and water tank evenness of wall thickness are difficult to control, and cold shut has more now roomy upper surface or the thin-walled place away from cast gate in the sand mo(u)ld cast molding, metal flow concourse, and Quench positions such as chill, stud.In order to reduce traditional casting water tank defective, prior art adopts the increase wall thickness to solve usually, will increase materials consumption and the energy consumption of water tank like this.How to guarantee under the water tank strength condition, maximization reduces the materials consumption of aluminum alloy, improve the inside and outside degree of finish of water tank, effectively reduce the water tank casting process and defectives such as cold shut, shrinkage cavity shrinkage porosity, wall unevenness be even occur, further reduce production costs, become those skilled in the art's problem demanding prompt solution.
The model utility content
The purpose of this utility model provides a kind of split die casting formula single-cylinder water cooled diesel engine water tank, it can optimize the casting technique of water tank, make water tank change metal pattern die casting into by the sand mo(u)ld cast inblock, can guarantee the uniformity of water tank wall thickness, reduce sand mold casting defectives such as cold shut, shrinkage cavity, shrinkage porosite, can reduce the materials consumption of aluminum alloy again, improve yield rate, reduce production costs.
The technological scheme that the utility model is taked is as follows:
A kind of split die casting formula single-cylinder water cooled diesel engine water tank, it is characterized in that: comprise upper box and lower box, end face at upper box is provided with water inlet, the inboard of sidewall is provided with the vertical stiffening rib in upper body around upper box, inboard end face at upper box is provided with the horizontal stiffening rib in upper body, be provided with body water cavity through hole in the bottom surface of lower box, the inboard of sidewall is provided with the vertical stiffening rib of lower body around lower box, inside bottom surface at lower box is provided with the horizontal stiffening rib of lower body, by soldered fixedly connected being integral hermetically, form a complete water tank between upper box and the lower box.
Further, the wall thickness of upper box and lower box be 1.5 the milli～3 millimeters.
Further, between upper box and lower box, be provided with and dock position structure.
Further, described butt joint position structure is: the interface at upper box is provided with two above locating studs, is provided with positioning hole with the locating stud equal number at the interface of lower box, and the position that locating stud and positioning hole are offered is corresponding.
Further, locating stud is arranged on the lower end surface of the vertical stiffening rib in upper body, and positioning hole is arranged on the upper-end surface of the vertical stiffening rib of lower body.
Further, described locating stud is cone, and described positioning hole is conical bore.
Further, the structure of upper box and lower box interface is monolateral open butt joint structure or double-edge open docking structure.
Because the utility model becomes the split welded structure with the integrated water tank architecture advances, the height dimension of the upper box of water tank and lower box reduces half like this, both can both adopt advanced metal pattern accurate die casting forming technique, the water tank wall thickness can precisely be controlled, wall thickness can be controlled at 1.5mm～2mm, on the intracavity sidewall of upper box and lower box, can precisely have additional stiffening rib arbitrarily, can guarantee the bulk strength of water tank, can reduce aluminum alloy material consumption significantly again, the die casting yield rate of die casting upper box and lower box increases substantially, between upper box and lower box, set up the butt joint position structure and can guarantee between the two positive accurate butt joint interlock fast, for follow-up welding provides condition.The interface structure of upper box and lower box is designed to monolateral open butt joint structure or the double-edge open docking structure is convenient to improve the join strength of soldered between the two.This split die cast, the airtight fixed structure mode of butt joint welding, good seal performance not only, casting defect is few, wall thickness is even, and is few with material, the efficient height, and cost is low, flat appearance is smooth, has improved the machining accuracy of single-cylinder water cooled diesel engine water tank, has improved the market competitiveness of Diesel Engine Complete Machine.
