Description
Technical field
The present invention relates to oil pump accessory manufactures field, and in particular to a kind of oil seal cover sand mo(u)ld manufacturing equipment.
Background technology
Oil pump is a kind of not only light but also compact pump, be a kind of oil pump with a shell by made by alumina-bearing material and
The movable moulded parts being arranged in the shell, wherein, the movable moulded parts at least in part by one kind it is sintered,
Make including at least a kind of material of the ferrous alloy of austenite, and the moulded parts wherein by made by a kind of sinterable material
Thermal coefficient of expansion with a thermal coefficient of expansion 60% for being at least the shell.
Oil seal cover is the important accessory on oil pump, and in currently available technology, oil seal cover is produced by sand casting
Processing, its manufacture process is：
Drawing：Conventional method is to obtain casting drawing and then drawing is sent to Foundry Works.This process can be in quotation
Complete.Nowadays, increasing client and casting manufacturer are replaced using CAD.
Mould：Mould is made of using wood or other metal materials in sand casting.In this process, we
Our engineer is required, makes die size slightly larger than finished product, difference therein is referred to as allowance for shrinkage.Wherein purpose is fusing gold
Belong to and being solidified and contraction with guaranteeing motlten metal to mould action, so as to prevent the cavity in casting process.
Coremaking：As long as coremaking is by being placed in resin sand grains in mould, to form the foundry goods of interior surface.Therefore core and mould
Space between tool eventually becomes casting.
Shaping：Need to prepare one pair of mould during melting shaping.Shaping is usually directed to the supporting frame of mould, pulls out
Mould makes it separate in casting cycle, and the core previously placed melts be then shut off mould mouth in a mold.
Cleaning：The purpose of cleaning is to remove sand grains, superfluous metal in polishing and foundry goods.Welding, desanding can change
The sand and scale that kind cast(ing) surface outward appearance is burned out all is removed, to improve the casting of appearance.Excessive metal and other emit
Mouth is clear.The steps such as polishing are further welded again.Finally check its defect and comprehensive quality.
Arrange：Before shipping, reprocessing.It is heat-treated again for it according to the requirement of different clients, is surface-treated, extra inspection
Look into.
In whole process, the coremaking stage is the sand mold molding stage due to higher to sand mo(u)ld precision prescribed, it usually needs flower
What a the expense long period can just do, and need workman to be operated by hand, and efficiency is low and quality is wayward.
