Abstract
A vertical casting technology for casting 20 steel balls once features that 20 section moulds (or sand moulds or alumyte moulds) are vertically arranged in single or multiple columns with runner to connect them and molten steel is poured into down gate. After balls are shaped, moulds are opened at 900 deg.C and the balls are quenched and then self-tempered. Its advantages are high utilization rate of molten steel and qualified rate of steel balls.
Description
The present invention relates to a kind of metal mould multiple row vertical steel ball casting mould.(method of multiple row vertical steel ball casting also can be used for sand mo(u)ld, aluminium vanadine mould).
Existing steel ball casting mould all is flat pattern cast, and the molten steel of running channel consume about 25% of the gross weight that accounts for have only 3/4ths utilization rate, and percent defective is higher, has caused very big waste.
A kind of steel ball casting metal pattern has been invented by Hebei Polytechnical College the year before, and pattern is single cast steel ball, also can save a part of molten steel, but production efficiency is low also undesirable, does not also have to excavate the potentiality of saving molten steel to the greatest extent and enhancing productivity.
Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned prior art, and a kind of utilization rate that steel ball casting improves molten steel and easy and simple to handle that makes is provided, and cost is low, the pattern that production efficiency is high.
The present purpose of the present invention can realize by following scheme, whole enforcement is undertaken by following operation: make a pattern template earlier, press the pattern of the same specification of designing requirement casting two fans of pattern plate, after machined, two fan patterns are lumped together, open wide behind the positional punch, steel ball in the pattern is connected under running channel (2), the garden taper type core on each position, two fan patterns are lumped together, fixing tight, rising head (3) erects up, at this moment just can water molten steel in pattern again.Molten steel is by down gate (1), enter running channel (2), falls into rising head (3) and enters steel ball (4).Shown in the Figure of description front section view, along the garden taper type core running channel (2) of half gradient type, fall in the steel ball die cavity of bottommost in first steel ball die cavity of top.Molten steel about the rightabout that molten steel flows into solidifies afterwards to 900 ℃ gradually, opens wide pattern towards stretching equably all around, falls steel ball in pattern, end of operation.The method of this multiple row vertical steel ball casting is used for sand mo(u)ld, aluminium vanadine mould, and effect is the same.This multiple row vertical steel ball casting mould is divided into a plurality of arrangements of vertical single file, and duplicate rows is to a plurality of ranking methods of multirow.
The present invention has following advantage: 1, production efficiency height, quality is good, saves man-hour.2, molten steel Utilization rate has reduced cost up to 92-95%.3, yield rate is up to 98-100%.4, ingate adopts extremely short garden taper type core, and it is good in the gravity feeding that molten steel is had at process of setting.5, the ingate between steel ball and steel ball is designed to the high conelet garden platform shape of 1-2mm, is keeping complete garden degree when making steel ball come off running channel.6, molten steel is not that the die cavity wall that flings into die cavity does not have localized burn, thereby has improved the service life of pattern.7, water, rising head adopts insulation material entirely, and (crushed crude pearlite, pornographic movie powder, aluminate cement, coal dust, coke powder, waterglass, water) has five kinds of prescriptions to manufacture.Sand core strength is big, can stop the setting rate of molten steel, and this insulation material can be used for the watering of various castings, rising head.
The present invention can make the steel ball casting yield rate reach more than 98% fully, and molten steel Utilization rate reaches more than 95%, obviously enhances productivity, and has fallen at the end cost, and steel ball quality is good.This arrangement is used for sand mold mould, aluminium Fan clay model equally, and effect is the same.
Figure of description face explanation: 1, down gate; 2, running channel; 3, rising head; 4, steel ball; 5, pattern.
Claims (3)
1, a kind of metal mould multiple row vertical steel ball casting mould, it is characterized in that the steel ball die cavity in the metal pattern is communicated with the vertical molten steel that pours into by garden taper type core running channel (2) through rising head (3), insulation material running channel (2), rising head (3) plays two effects, it when pouring into molten steel cast gate, molten steel is the rising head of feeding steel ball after watering full die cavity, (the method for multiple row vertical steel ball casting, also can be used for sand mo(u)ld, aluminium vanadine mould), the method of this multiple row vertical steel ball casting is used for sand mo(u)ld, aluminium vanadine mould, effect is the same, this multiple row vertical steel ball casting mould, be divided into a plurality of arrangements of vertical single file, duplicate rows is to a plurality of ranking methods of multirow.
2, metal mould multiple row vertical steel ball casting mould according to claim 1, it is characterized in that: garden taper type running channel (2), rising head (3) adopt insulation material (crushed crude pearlite, pornographic movie powder, aluminate cement, coal dust, coke blacking, waterglass, water) to have five kinds of prescriptions to manufacture entirely, be applicable to different insulation needs, be used for the watering of cast iron, cast steel, cast copper, the various foundry goods of cast aluminium, rising head.
3, metal mould multiple row vertical steel ball casting mould according to claim 1 is characterized in that (method of multiple row vertical steel ball casting also can be used for sand mo(u)ld, bauxite mould)
