Description
Technical field
The utility model belongs to casting technology field, especially relates to the casting technique of single cylinder serial diesel engine body, also relates to single cylinder diesel body casting mould.
Background technology
In the prior art, mould therefor comprises external mold and inner core in the casting technique of single cylinder diesel body, and wherein external mold comprises upper die and lower die, and inner core comprises core and following core.The mixture manufacturing that external mold wherein normally is made up of sand, bentonite, coal dust, molding sand powder.In manufacture process, at first, said mixture put into to have roll the puddle mixer of pulverizing function and mix.In mixed process, also to add an amount of water, then, the material that ground and mixed is good is inserted sandbox (as shown in Figure 1), by craft or moulding machine vibration pressurization, mold the upper die and lower die of external mold, in having the counterdie of sandbox, put into inner core, again patrix sandbox 01 is buckled on the counterdie sandbox 02, by the positioning lock fixer on two sandboxes up and down---normally be arranged in the vertical pin-and-hole 03 at upper and lower mould sandbox two ends and alignment pin 04 be set and locking component 06 locking location is set on the locking post 05 on the outer wall of upper and lower mould sandbox two ends.Carry out the molten iron casting afterwards.The molten iron sprue gate of existing mold and transition running channel are arranged on the outside of corresponding diesel-engine body lateral edge, and steam vent is located at the spindle hole place of corresponding diesel-engine body.Like this, just form a horizontal running channel iron staff 08 and a vertical cast gate iron block 08a (shown in Fig. 2,3) who equates substantially with the body side length in the side of body foundry goods 07.
There are following shortcoming in above-mentioned existing technology and mould therefor:
1. the external mold intensity that outer mold materials and the moulding of sandbox pressurization and vibration are made is low, moisture, causes the foundry goods that casts out to have pore and sand holes, and product qualified rate is lower.
2. external mold sandbox locking location structure, lower for positioning accuracy between the upper and lower mould, the clearance of the core print cooperation place of external mold and inner core is bigger, cause two sandboxes of upper and lower mould to misplace easily, these problems can cause hard edges to increase, and outward appearance is coarse not attractive in appearance, make that also allowance increases in the follow-up machined of body, cutting tool wear consumption height, cutting-out iron filings amount is big.Thus, make mach efficient reduce, increased the foundry return amount simultaneously, reduced the molten iron effective rate of utilization.
3. existing processing step is various, process is complicated, and the material ground and mixed of external mold is vibrated extrusion modling with being filled in the sandbox, and installations and facilities are many, and operating personnel are many, and labour intensity is big, and production efficiency is low.
4. the cast gate of mould design makes that the transition running channel is long, and molten iron heat conduction variation is prone to the cold shut phenomenon, causes foundry goods to scrap and form the crack on foundry goods.Long transition running channel also forms the horizontal running channel iron staff that a weight is about 9Kg on foundry goods.This has increased the amount of labour of removing iron staff with regard to the post-production of giving foundry goods, the transition running channel iron staff that this is long, add noted earlier because of last drag box fallibility position, the low hard edges that causes of precision, the foundry return amount that increases can reach 15-20%, increase the energy-output ratio of fusing foundry return thus and the pollution of environment has been destroyed, reduced the effective rate of utilization of molten iron.
The body mold and pattern for casting tool of diesel engine in the prior art, the upper and lower core of inner core wherein have the resin sand material of use sand and mixed with resin to make.The sand mold of this material on the make only needs with the puddle mixer mixing sand and the resin that only have agitating function, solidifies through cold core machine moulding with " triethylamine " to get final product again.The mold strength height that this technology is made, the precision height, quality is good, and technology is simple.But because cost is too high, the existing very low product of this added value of single cylinder diesel body in its external mold is produced, does not use this manufacturing process and the material of above-mentioned inner core.
How the technology and the material of inner core manufacturing can be used in the external mold manufacturing, can not improve again simultaneously, even can reduce single cylinder diesel body manufacturing cost, and can significantly improve its production efficiency and economic benefit, can also improve the quality of foundry goods simultaneously.It is problem to be solved in the utility model.
