Abstract
The invention discloses a pressure casting mould for a universal internal combustion engine box body. The pressure casting mould comprises a pressure casting mould body, a convex die and a sliding block which are arranged on the pressure casting mould body, wherein 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 cylinder sleeve shaft is fixedly arranged on a cylinder sleeve shaft installation part on the convex die, an installation face of the cylinder sleeve shaft installation part is set to be a vertical shape, a pattern draft of the convex die is adopted as 1.5 degrees, and a cushion area is arranged in the end part of the sliding block cylinder sleeve shaft. According to the pressure casting mound, a useless aluminum wrapping layer of the air cylinder sleeve in a port part inside the internal combustion engine box body can be eliminated, and the situation of breaking in the root part of the convex die can not occur.
Description
Technical field
The invention belongs to die casting field, relate in particular to a kind of general-purpose engine casing die casting.
Background technology
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 the normal work of all parts, in casing, pass through reciprocating piston driving bent axle, the machine oil of bottom is stirred, machine oil is splashed to and on link pins, piston and gear, forms lubricated effect, its advantage is simple in structure, 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 box inside oral area, this aluminium coating is to remove and use ball blast technique finally to clear up by knocking, consequently accidentally have the loosening aluminium bits of part residual, also cannot remove completely by the machining manual type of living, finally cause the wearing and tearing in advance of engine.
In addition, when the die casting of such casing of research, finding, very easily there is the accident of punch root cracking in the region 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 has many combustion motor casings, 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 top box eddy current.Yet the IC engine airframe of prior art is not all made improvement to above-mentioned mentioned weak point.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art part, and a kind of general-purpose engine casing die casting is provided, and it can eliminate cylinder jacket at the useless aluminium coating of internal combustion engine box inside oral area, and the situation of fracture can not occur the root of punch simultaneously.
To achieve these goals, the present invention is by the following technical solutions:
A kind of general-purpose engine casing die casting, comprise die casting body, be located at punch and slide block on die casting body, on described slide block, be fixed with slider cylinder sleeve, on slider cylinder sleeve, be arranged with cylinder jacket, 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 °, in the end of slider cylinder sleeve, is provided with buffering area.A kind of general-purpose engine casing die casting proposed by the invention, by the installed surface of punch installation portion is set to vertical configuration, punch adopts the pattern draft of 1.5 ° simultaneously, the sealing surface that punch installation portion and cylinder jacket have formed like this, eliminated the useless aluminium coating of cylinder jacket at box inside oral area 0 ~ 2mm, the generation of fundamentally having stopped aluminium bits, has effectively extended engine bulk life time; In the end of slider cylinder sleeve, be provided with buffering area simultaneously, slider cylinder sleeve can not touch and wear with punch more like this, and the sealing surface that utilizes cylinder jacket and punch to form seals aluminium water, even when cylinder jacket is long, also only can crush cylinder jacket, 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 inclined-plane.In this preferred version, at slider cylinder cover shaft end, be provided with inclined-plane, can by oral area, start the cavity that inside foundry goods reduces so that slider cylinder sleeve produces one like this, once there is the situation that aluminium liquid is scurried into, 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, between slider cylinder sleeve and cylinder jacket, loosening situation can not occur.
As preferably, described slider cylinder sleeve adopts the manufacture of the Sweden DIEVAR of Assab material to form, modified rear hardness 46～48HRC.In this preferred version, slider cylinder sleeve adopts the manufacture of the Sweden DIEVAR of Assab material to form, modified rear hardness 46～48HRC, and slider cylinder sleeve has good thermoplasticity and red brittleness, and its quenching degree is strong, and heat treatment performance is good.
Compared with prior art, the present invention has following beneficial effect: (1) has eliminated the useless aluminium coating of cylinder jacket oral area 0 ~ 2mm inside internal combustion engine, thereby can effectively protect internal combustion engine, avoids internal combustion engine that the phenomenon of wearing and tearing occurs; (2) can there is not the accident of punch root cracking in the region that punch contacts with slider cylinder sleeve, the situation of effectively having avoided punch to damage.
