Description
Technical field
The utility model relates to a kind of metal die-casting mold, especially relates to a kind of Novel air cylinder barrel die casting.
Background technology
Cylinder barrel is a vitals in the air motor, and air motor is the device that compressed-air actuated pressure energy is converted to the mechanical energy of rotation.Its effect is equivalent to motor or hydraulic motor, namely exports torque and rotates with driving mechanism.
Cylinder barrel in the past is assembled together with screw with front end-plate and end plate in pneumatic tool, when using pneumatic tool, cylinder barrel and both assembly connection places reveal easily, and this just has very high requirement to precision and the surface quality of the contact-making surface of cylinder barrel and front end-plate, end plate.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome cylinder barrel and front end-plate in the prior art, the deficiency that reveal easily the end plate junction, consider to adopt the new-type cylinder barrel of integral design, former cylinder barrel is become the new-type cylinder barrel of an integral body with the front end-plate Integration Design, and the cylinder interior size redesigned, this has just proposed very high requirement to die casting, for casting out that size meets the demands and with the Novel air cylinder barrel foundry goods of the tiny characteristics such as technology groove, the utility model provides a kind of Novel air cylinder barrel die casting, produce the Novel integral cylinder barrel that meets the demands, and then promote the pneumatic tool progress; The cylinder barrel appearance zero defect of producing can be assemblied in the pneumatic tool after processing, has realized purpose of design fully.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Novel air cylinder barrel die casting, adopt vertical-parting, comprise cover half, dynamic model, transmission mechanism, at least 2 slide blocks, running gate system and overflowing system, the upper surface of described cover half has fixed mold, the lower surface of described dynamic model has dynamic mould core, described transmission mechanism comprises Angle Pin, guide pin bushing, push rod and dynamic model push-rod hole, each slide block all has guide pin bushing, described Angle Pin and guide pin bushing are connected, described slide block is connected by Angle Pin and guide pin bushing and dynamic model, and slide block and cover half are linked; The inner surface of all slide blocks forms the profile of cylinder barrel outer surface, and the profile of described fixed mold, dynamic mould core and slide block forms die cavity jointly; Described running gate system is comprised of the cross gate that is opened in the cover half upper surface and ingate, and described ingate is communicated with cross gate; Described overflowing system is comprised of dynamic model slag trap and cover half slag trap, and described dynamic model slag trap and cover half slag trap are looped around respectively around dynamic mould core and the fixed mold; Described push rod and dynamic model push-rod hole are slidingly matched, and the dynamic model push-rod hole is arranged on the dynamic model, and are communicated with die cavity.
Have two ingates, described cross gate is divided into two, and is communicated with two ingates respectively.Adopt this structure, molten metal can not produce eddy current bag gas and oxide inclusion defective after cross gate enters die cavity by ingate.
Have 4 described slide blocks, because the inner surface structure of cylinder barrel is complicated, from the four direction exhaust, the shape of cylinder barrel is complicated, if exhaust is bad, is easy to during moulding air is enclosed in the goods, causes product defect in the time of can making things convenient for moulding like this.During mold work by the gap exhaust between slide block and cover half, slide block and the dynamic model, original air just can be discharged after being pressed into motlten metal easily in the die cavity, this has just reduced the flow resistance of motlten metal, increased the flowability of motlten metal, thereby so that motlten metal can arrive each position of die cavity smoothly, the product of die cast is not easy to occur defective thus, has increased the quality of product.
Described dynamic mould core is provided with two circular-arc raised structures, with the moulding process groove.
Offer cooling water channel in the described cover half, the thermal balance during with assurance die casting can prolong die life on the one hand, prevents the mould aging cracking, can guarantee that on the other hand cast temperature is constant.
The mold work process: during the mould matched moulds, under the guiding and positioning action of Angle Pin and guide pin bushing, Clamping System drives dynamic model and moves to the cover half direction, four slide blocks are under the Angle Pin effect simultaneously, arrive the operating position, make mould closed, and provide enough clamp force locking dies by Clamping System.Then begin die casting, by die casting machine work hand aluminium liquid is poured into pressing exerts pressure in the chamber and through injection mechanism enters mould by cross gate, ingate, after pressurize a period of time, Clamping System drives dynamic model to moving away from the cover half direction, four slide blocks separate under the Angle Pin effect simultaneously, and then push rod is released the cylinder barrel foundry goods from mould.During matched moulds, push rod resets, and mould is prepared next time die casting.
The beneficial effects of the utility model are, a kind of Novel air cylinder barrel die casting of the present utility model, the Novel air cylinder barrel of producing has been integrated traditional cylinder barrel and front end-plate, compares with traditional cylinder barrel to have considerable advantage, improves such as weight saving, Service life, air-tightness; This mould structure is simple, and not fragile, the life-span is long, can produce the cylinder barrel foundry goods that meets the demands fully, and surface quality of continuous castings is good, and production efficiency is high.
