Abstract
The utility model discloses a general combustion motor box body die-casting die which comprises a die-casting die body, a male die and a sliding block, wherein the male die and the sliding block are arranged on the die-casting die body. A sliding block cylinder sleeve shaft is fixedly arranged on the sliding block. An air cylinder sleeve is sleeved on the sliding block cylinder sleeve shaft. The sliding block cylinder sleeve shaft is fixedly arranged on a cylinder sleeve shaft installation part of the male die. The installation face of the cylinder sleeve shaft installation part is vertical. A draft angle of 1.5 degrees is adopted by the male die. A buffering area is arranged on the end portion of the sliding block cylinder sleeve shaft. The general combustion motor box body die-casting die is capable of eliminating a useless aluminum coating of an air cylinder sleeve on the opening portion inside a combustion motor box body, and meanwhile the root portion of the male die can not be cracked.

Technical field
The utility model belongs to the die casting field, relates in particular to a kind of general-purpose engine casing die casting.
Background technology
The general-purpose engine casing is the main body of internal combustion engine structure, it is the support frame that all parts of internal combustion engine and annex are installed, guarantee that all movement parts keep mutual alignment accurately in the course of the work, the Cooling and Lubricator passage of internal combustion engines is set, guarantee the necessary Cooling and Lubricator of all parts normal operations, pass through reciprocating piston driving bent axle in casing, the machine oil of bottom is stirred, machine oil is splashed to and forms lubricated effect on link pins, piston and gear, its advantage is simple in structure, the body lightweight.Its weak point is: aluminium bits residual or loosening in machining or casting can cause the wearing and tearing of motion and cylinder and piston by the propagation of machine oil, find after deliberation, reason due to pattern draft, cylinder sleeve has the useless aluminium coating of 0 ~ 2mm gradual change at the box inside oral area, this aluminium coating is to remove and use ball blast technique to clear up at last by knocking, consequently accidentally have the loosening aluminium bits of part residual, also can't remove fully by machining living person work mode, finally cause the wearing and tearing in advance of engine.
In addition, find when the die casting of such casing of research, the accident of punch root cracking very easily occurs in the zone that punch contacts with the slider cylinder sleeve that cylinder sleeve is installed, and this did not almost occur on the mould of other classifications.
According to the retrieval, in the prior art, the improvement technology that many combustion motor casings are arranged, as Chinese patent Granted publication number: CN201415255Y, Granted publication day: on 03 03rd, 2010, a kind of casting device of IC engine airframe is disclosed, it has adopted PES evaporative pattern apperance and has been positioned in sandbox apperance is vertical, be 10-15 degree vanning back-up sands with vertical direction, it can guarantee molding sand filling and the packing requirement of PES evaporative pattern apperance when back-up sand jolt ramming moulding; Chinese patent Granted publication number: CN201921988U, Granted publication day: on 08 10th, 2011, a kind of diesel engine body casting mold is disclosed, this mould adopts the structure of bottom gating system, has effectively eliminated the top box eddy current.Yet the IC engine airframe of prior art is not all made improvement to the above-mentioned weak point of mentioning.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art part, a kind of general-purpose engine casing die casting to be provided, and it can eliminate cylinder jacket at the useless aluminium coating of internal combustion engine box inside oral area, the situation that the root of punch can fracture simultaneously.
To achieve these goals, the utility model is by the following technical solutions:
A kind of general-purpose engine casing die casting, comprise the die casting body, be located at punch and slide block on the die casting body, be fixed with the slider cylinder sleeve on described slide block, be arranged with cylinder jacket on the slider cylinder sleeve, the slider cylinder sleeve is fixed on the cylinder sleeve axle installation portion of punch, the installed surface of cylinder sleeve axle installation portion is set to vertical configuration, and described punch adopts the pattern draft of 1.5 °, is provided with buffering area in the end of slider cylinder sleeve.A kind of general-purpose engine casing die casting that the utility model proposes, be set to vertical configuration by the installed surface with the punch installation portion, punch adopts the pattern draft of 1.5 ° simultaneously, punch installation portion and cylinder jacket form the sealing surface of completing like this, eliminated the useless aluminium coating of cylinder jacket at box inside oral area 0 ~ 2mm, fundamentally stop the generation of aluminium bits, effectively extended the engine bulk life time; Simultaneously be provided with buffering area in the end of slider cylinder sleeve, the slider cylinder sleeve can not touch with punch again and wear like this, and the sealing surface that utilizes cylinder jacket and punch to form seals aluminium water, even when cylinder jacket is long, the cylinder jacket of yet only can crushing can not cause damage to punch and slider cylinder sleeve.
As preferably, the length of described buffering area is 0.5 ~ 1.0mm.In this preferred version, the length of buffering area is arranged to the length of 0.5 ~ 1.0mm, the buffering area of this length, and the sealing surface that can more effectively utilize cylinder jacket and punch to form seals aluminium water.
As preferably, the shaft end of described slide block cylinder sleeve is provided with the inclined-plane.In this preferred version, be provided with the inclined-plane at slider cylinder cover shaft end, can begin by oral area the cavity that inside foundry goods reduces so that the slider cylinder sleeve produces one like this, in case the situation that aluminium liquid is scurried into occurs, end at cavity will produce broken line naturally, and the aluminium liquid after solidifying just can be pounded out by integral body easily.
As preferably, the length on described inclined-plane is 15mm, and the gradient on described inclined-plane is 2 °.In this preferred version, the length on inclined-plane is arranged to 15mm, and the gradient on inclined-plane is set to 2 °, and what aluminium liquid can be convenient after solidifying in such cavity is pounded out by integral body.
As preferably, described slider cylinder sleeve and described cylinder jacket matched in clearance, the diameter of matched in clearance is 0.23 ~ 0.25mm.In this preferred version, slider cylinder sleeve and described cylinder sleeve matched in clearance, the diameter of matched in clearance is 0.23 ~ 0.25mm, situation about can not become flexible between slider cylinder sleeve and cylinder jacket.
As preferably, described slider cylinder sleeve adopts the manufacturing of the Sweden DIEVAR of Assab material to form, modified rear hardness 46～48HRC.In this preferred version, the slider cylinder sleeve adopts the manufacturing of the Sweden DIEVAR of Assab material to form, modified rear hardness 46～48HRC, and the slider cylinder sleeve has thermoplasticity and red brittleness preferably, and its quenching degree is strong, and heat treatment performance is good.
