Description
Technical field
The utility model relates to the die casting technical field, especially handle rear case component die casting.
Background technology
The handle bonnet is a vitals of pneumatic tool housing, because the handle bonnet is appearance member, is again functor, and its surface quality is had relatively high expectations, and directly affects the technological progress of air tool performance and pneumatic tool industry.
Restriction because of handle rear cover structure and technique, domestic manufacturer adopts gravitational casting to produce the handle bonnet mostly at present, and gravitational casting efficient is low, surface finish of casting is poor, therefore poor by the handle bonnet surface quality of gravitational casting, after surface spraying black gray expandable plastics, after handle, the signs such as numeral of cap surface even reach the unclear degree of differentiating outside.And at present the handle rear cover structure is monoblock type, inevitably will be first with it during breeder tube in the middle of boring the handle bonnet outside shell auger saturating, so both affected products air tightness, increased again this unnecessary operation of manual stifled shell aperture.
New-type handle bonnet adopts split-type design, former handle bonnet is designed to the combination of spool and rear cover housing, after adopting split-type design, spool is relative with the bonnet shell mechanism simple, therefore can consider to produce both with the die casting mode, and if produce both with the die casting mode, need two overlap die castings, so both cost was improved greatly, made again Efficiency Decreasing.
The utility model content
The technical problems to be solved in the utility model is: overcoming does not increase cost in the situation that mould in prior art adopts split-type design and production efficiency is high, a kind of handle rear case component die casting is provided, designed the dimorphism chamber, in the situation that do not increase cost and high spool and the handle bonnet produced of production efficiency, to satisfy the designing requirement of New type detachable handle bonnet, the spool of producing and bonnet case surface quality are good, the appearance zero defect.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of handle rear case component die casting, adopt vertical-parting, comprise cover half, dynamic model and Clamping System, have spool core and bonnet shell core on described dynamic model, form spool die cavity and two die cavities of bonnet shell die cavity after described fixed half and moving half matched moulds, offer the spool cross gate and the shell cross gate that is communicated with bonnet shell die cavity in communicating valve core pattern chamber on described dynamic model.
The periphery that is positioned at the spool core on described dynamic model is provided with can be to the first slide block, the second slide block and the 3rd slide block of spool core relative sliding, and the end towards the spool core on the first slide block, the second slide block and the 3rd slide block offers square opening.
For adapting to the designing requirement of rear cover housing, described bonnet shell core is provided with rear cover housing mold insert.First can avoid the mould complicated processing, reduces costs, time saving and energy saving, and second can be convenient to change after mold insert partly damages, and avoids mould to scrap, and saves cost.
Further for discharging the bits that produce in press casting procedure, also has mould overflowing system, described mould overflowing system comprises spool slag trap and rear cover housing slag trap, and described spool slag trap is arranged on cover half, and described rear cover housing slag trap is arranged on dynamic model.
Further for ease of exhaust, described dynamic model is provided with the exhaust passage that is communicated with rear cover housing slag trap, has exhaust clearance between spool die cavity and the first slide block, the second slide block, the 3rd slide block and fixed half and moving half.Reduced the flow resistance of motlten metal, increased the mobility of motlten metal, thereby made motlten metal can arrive smoothly each position of die cavity, the product of die cast is not easy to occur defective thus, has improved the quality of product.
Described spool cross gate and spool die cavity connectivity part have the spool ingate, and shell cross gate and bonnet shell die cavity connectivity part have the shell ingate.Cross gate and ingate all pass through Calculation Simulation, flow into the molten metal of die cavity through two runners, substantially simultaneously be full of die cavity, therefore can guarantee the quality consistency of every die casting, can not produce eddy current bag gas and oxide inclusion defective after molten metal enters die cavity by cross gate and ingate simultaneously.
For realizing automatic demoulding, described dynamic model is provided with the push rod that ejects spool and rear cover housing when dynamic model when moving away from the cover half direction.
The beneficial effects of the utility model are, handle rear case component die casting of the present utility model adopts two die cavities, and the design of the running gate system of mould and overflowing system is most important to the casting quality quality.The running gate system of mould is located on dynamic model, and two runners are arranged, and respectively aluminium liquid is imported bonnet shell die cavity and spool die cavity during die casting.Cross gate and ingate all pass through Calculation Simulation, flow into the molten metal of die cavity through two runners, substantially simultaneously be full of die cavity, therefore can guarantee the quality consistency of every die casting, can not produce eddy current bag gas and oxide inclusion defective after molten metal enters die cavity by cross gate and ingate simultaneously.Cover half is provided with the spool slag trap, dynamic model is provided with rear cover housing slag trap, after dynamic model, the cover housing slag trap outside offers the exhaust passage, the spool die cavity is by the gap exhaust between slide block and fixed half and moving half, adopt the exhaust passage, in die cavity, original air just can be discharged after being pressed into motlten metal easily, this has just reduced the flow resistance of motlten metal, increased the mobility of motlten metal, thereby make motlten metal can arrive smoothly each position of die cavity, the product of die cast is not easy to occur defective thus, has improved the quality of product.
Rear cover housing and spool face quality that the utility model is produced are good, and the appearance zero defect is combined into the handle bonnet and can be used in pneumatic tool through processing and after being press-fitted.This mould adopts two die cavities, and production efficiency is high, and has reduced the expense of making die casting, can produce the handle rear cover casting that meets the demands fully, and casting quality is excellent.
