Description
Technical field:
The utility model belongs to engine cast casting technical field, is specifically related to a kind of aluminum alloy cylinder cover gravity casting mould.
Background technology:
In order to make the aluminum alloy melt cast form the chamber structure of cylinder cap, in existing aluminum alloy cylinder cover gravity casting mould, the combustion chamber part that generally will form cylinder cap is all made independently combustion chamber insert, is fastened on the bed die piece with screw again.In the process of casting, because aluminum alloy melt exists the very big temperature difference by the initial liquid condition solid state of moulding to the end, cause the gravity casting mould to expand with heat and contract with cold, make the volume that forms the combustion chamber of cylinder cap in the gravity casting mould not reach requirement., make in process of production for this reason, need adjust height that respective combustion chamber inserts sometimes so that the volume of combustion chamber reaches requirement.At present, a kind of like this regulative mode of general employing promptly fills up the height that copper sheet is regulated combustion chamber insert between combustion chamber insert and bed die piece, finally make the volume that forms the combustion chamber of cylinder cap in the gravity casting mould reach requirement.And this height change that realizes combustion chamber insert by the mode of filling up copper sheet, very trouble on the one hand operates, comparatively common on the other hand copper sheet thickness generally has only 0.1mm, 0.2mm and 0.3mm, make the height of regulating combustion chamber insert have the sudden change of jumping characteristic, be to rise on the combustion chamber or the height that descends is at least 0.1mm, can not make combustion chamber insert not have the adjusting of sudden change, i.e. step-less adjustment continuously.
The utility model content:
The technical problems to be solved in the utility model is: provide a kind of easy to adjust, regulate and do not have sudden change continuously, can carry out the aluminum alloy cylinder cover gravity casting mould of step-less adjustment.
For solving the problems of the technologies described above, the utility model adopts a kind of like this aluminum alloy cylinder cover gravity casting mould: it comprises combustion chamber insert and bed die piece, and the below of described combustion chamber insert is provided with the stepless regulating mechanism that the bottom surface of top end face and combustion chamber insert is close to.
After adopting above structure, the utility model compared with prior art, have the following advantages: owing to set up stepless regulating mechanism, and the top end face of this stepless regulating mechanism and the bottom surface of combustion chamber insert are close to, when needs are regulated the height of combustion chamber insert, only need slowly regulate stepless regulating mechanism, just can easily realize the height change of combustion chamber insert, and the variation of combustion chamber insert height is not have sudden change continuously in the process of regulating, and a kind of like this regulative mode is a step-less adjustment.
As a kind of improvement, stepless regulating mechanism is a closely-pitched adjusting screw(rod), and the bed die piece is provided with vertically the fine thread through hole that connects, and the body of rod of closely-pitched adjusting screw(rod) just screws in this fine thread through hole, and the top end face of the body of rod and the bottom surface of combustion chamber insert are close to.When needs are regulated the height of combustion chamber insert, only need slowly regulate the closely-pitched adjusting screw(rod), just can realize the height change of combustion chamber insert, and realize a kind of step-less adjustment of being changed to of combustion chamber height by screwing of fine thread.In adjustment process, the height change of combustion chamber insert does not have sudden change continuously.The bar head below of this closely-pitched adjusting screw(rod) also is provided with pressure strip, and pressure strip is installed in the lower end of bed die piece by screw.After regulating height, pressure strip is fixed tightly on the bed die piece, can prevent effectively that just the closely-pitched adjusting screw(rod) from getting loose.
Improve as another kind, stepless regulating mechanism is a closely-pitched adjusting screw(rod), and the lower end of bed die piece is fixedly connected with connecting plate by screw, connecting plate is provided with the fine thread through hole that vertically connects, the middle and upper part of the body of rod of closely-pitched adjusting screw(rod) just screws in this fine thread through hole, and the top end face of the body of rod and the bottom surface of combustion chamber insert are close to.When needs are regulated the height of combustion chamber insert, only need slowly regulate the closely-pitched adjusting screw(rod), just can realize the height change of combustion chamber insert, and realize a kind of step-less adjustment of being changed to of combustion chamber height by screwing of fine thread.In adjustment process, the height change of combustion chamber insert does not have sudden change continuously.The lower end of the body of rod of this closely-pitched adjusting screw(rod) also is combined with clamp nut.After regulating height, tighten clamp nut, can prevent effectively that just the closely-pitched adjusting screw(rod) from getting loose.
As further improvement, the bar head of closely-pitched adjusting screw(rod) is the shape that matches with spanner clamping place, has made things convenient for spanner clamping bar head to regulate.
