Technical field
The utility model relates to a kind of automobile engine cylinder-body casting sand mould structure of falling withdrawing pattern, belongs to technical field of automobile engine.
Background technology
Automobile engine is the heart component of automobile, the complex machines being formed by a plurality of mechanisms and system, and its Main Function is to realize heat energy to the conversion of mechanical energy.Housing assembly is the skeleton of engine, and all major parts and the annex of engine is installed, and bears the various load in motion.By cylinder body, the crankshaft connecting rod system of engine and valve actuating mechanism and fuel feeding, skidding, the system such as cooling are connected into an integral body, the crudy of cylinder body directly affects the performance of engine.Its structure has left and right sides to hang face, front/rear end.The housing assembly of traditional engine is mainly comprised of cylinder body, cylinder or cylinder jacket, cylinder cap, head gasket and oil sump etc.Because the function of cylinder body has determined that it is complex-shaped, wall is thin, be box-shaped, and several only pits of machining are arranged at its top, for cylinder jacket is installed.Its underpart and crankcase top are made of one, so cavity is more, but stressed serious, so it should have very high rigidity, also to reduce casting section thickness, thereby alleviate its weight simultaneously.The stressing conditions that can know cylinder body according to the principle of engine is very complicated, need to have enough intensity, rigidity, wearability and vibration resistance, therefore cylinder block material is had to higher requirement.The material of cylinder body has plain cast iron, alloy cast iron and aluminium alloy etc.China's engine cylinder-body generally adopts HT200, HT250 casting pig, alloy cast iron and aluminium alloy.
Therefore, this just requires to adopt a kind of relatively accurate manufacture method in automobile engine cylinder-body casting process, to avoid producing artificial defect in manufacture process, reduces the processing capacity of machining, guarantees that each relative dimensions of engine cylinder-body meets the requirements.
Utility model content
The purpose of this utility model is: overcome the defect that prior art exists, a kind of automobile engine cylinder-body casting sand type structure is provided, the manufacturing defect that can avoid manual operation to exist, can prevent from again rising outside termination, is reducing workman's operational sequence
Meanwhile, improved again the uniformity of product size, guaranteed that each relative dimensions of engine cylinder-body meets the requirements.
The purpose of this utility model realizes by following technical proposals:
A kind of automobile engine cylinder-body casting sand mould structure of falling withdrawing pattern, comprises main core, rising head core, and left and right external form core and forward and backward termination core, is characterized in that: described rising head core and left and right sides outside core fall withdrawing pattern and coordinate.
As preferably, it is 86 °～88 ° that described rising head core and left and right sides outside core fall the angle that withdrawing pattern coordinates.
As preferably, it is 87 ° that described rising head core and left and right sides outside core fall the angle that withdrawing pattern coordinates.
As preferably, described left and right external form core cooperatively interacts and forms and coordinate bayonet socket in forward and backward end, and front end core is arranged in the cooperation bayonet socket of leading section, and follower head core is arranged in the cooperation bayonet socket of rearward end.
As preferably, top and the bottom of described cooperation bayonet socket is " protruding " font opening.
The beneficial effects of the utility model: the utility model adopts rising head core and the left and right sides outside core matching design of falling withdrawing pattern, utilize external form to clamp, and have reduced placement foundary weight, prevented that rising head from lifting case, both guarantee cylinder body size, reduced again workman's operational sequence, alleviated workman's labour intensity; Left and right external form core and forward and backward termination core are bayonet socket design, utilize the cooperation bayonet socket of external form core and termination core to carry out self-locking, both the manufacturing defect of having avoided manual operation to exist, has prevented from again opening outside termination, has guaranteed that each relative dimensions of engine cylinder-body meets the requirements.
