Its disadvantages are: the transmission of residual or loose aluminum chips in machining or casting through engine oil will cause wear and tear on the moving mechanism, cylinder and piston. After research, it is found that due to the draft angle, the cylinder liner is on the inside of the box. There will be a useless aluminum clad layer with a gradual change of 0~2mm in the mouth. The aluminum clad layer is removed by knocking and finally cleaned by shot blasting. completely removed, eventually causing premature engine wear
Yet the internal combustion engine block of prior art all does not improve above-mentioned weak point

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
[0001] technical field [0002] The invention belongs to the field of die-casting molds, in particular to a die-casting mold for a general internal combustion engine casing. Background technique [0003] The general internal combustion engine case is the main body of the internal combustion engine structure. It is the supporting framework for installing all parts and accessories of the internal combustion engine, ensuring that all moving parts maintain accurate mutual positions during the working process, and setting the cooling and lubrication channels inside the internal combustion engine to ensure that all parts are normal. For the cooling and lubrication necessary for work, the crankshaft is driven by the reciprocating piston in the box to stir the oil at the bottom, and the oil splashes on the link pins, pistons and gears to form lubrication. Its advantages are simple structure and lightweight body. Its disadvantages are: the transmission of residual or loose aluminum c...
