Description
Technical field
The present invention relates to squeeze casting mould technical field of structures, refer to the extrusion casint system of the short vehicle frame of a kind of wheelchair especially.
Background technology
Extrusion casint combines the advantage of casting and forging, is the process of a kind of high-quality, efficiently metal material near-net-shape, can be used for production structure complexity, foundry goods that combination property is higher.Short vehicle frame is important carrying parts on wheelchair, and foundry goods side wall thickness is 6mm, and bearing mounting hole place cross section wall thickness is comparatively large, very easily because ingate feeding deficiency produces shrinkage porosity defect of contraction cavity; Cast-internal is provided with reinforcement, and structure is more complicated, and the bleb rate that traditional ingate feeding manner is produced is comparatively large, and after heat treatment, cast(ing) surface distortion is comparatively large, and ingate is comparatively large, and not easily excise, larger otch increases the machined difficulty of foundry goods.The steady filling how realizing aluminium liquid and the smooth transmission how realizing pressure are two large difficult points of squeeze casting technology, and reasonably the realization of extrusion casint system to this two large difficult point plays vital effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide the extrusion casint system of the short vehicle frame of a kind of wheelchair, this system comprises material handle, long main running channel, short main running channel, divide running channel, foundry goods die cavity, cinder ladle and exhaust block, material handle extends a long main running channel and a short main running channel respectively along the left and right sides, long main running channel and short main running channel form the Semi surrounding type structure surrounding a foundry goods die cavity side, long main running channel arranges plural point of running channel with short main running channel in the side be connected with foundry goods die cavity, be connected with foundry goods die cavity by a point running channel, not besieged side arranges plural cinder ladle and plural exhaust block to foundry goods die cavity, not besieged two end faces of foundry goods die cavity arrange a cinder ladle respectively, divide on running channel and ingate is set, exhaust block on the not besieged side of foundry goods die cavity is connected with cinder ladle.
Wherein, running channel is divided to be connected with foundry goods die cavity reinforcement position.Main running channel is arranged on longer side, length is consistent with foundry goods side with shape, the overall theory structure in monolateral cast, like this, make the flowing overall in die cavity of aluminium liquid have single towards directionality, avoid aluminium liquid to collect at foundry goods and occur cold shut, also reduce the porosity of foundry goods, improve the mechanical property of foundry goods.And aluminium liquid is overall toward a direction flowing, decreases aluminium liquid phase and hand over the phenomenon of colliding and interfering, aluminium liquid flowing velocity can be improved like this, although make the speed of filling whole die cavity for monolateral cast aluminium liquid can not reduce too much.
Point running channel is wherein several is arranged on reinforcement position, to the direct filling in this position, is convenient to shaping and feeding; Several points of running channels are arranged on dead eye thick heavy in section place in addition, increase feeding effect, improve the Shrinkage cavity defect at this position.Divide running channel small and scattered, be convenient to excise ingate, and otch is little on cast(ing) surface impact.
The beneficial effect of technique scheme of the present invention is as follows:
In such scheme, aluminium liquid enters a point running channel along main running channel, directly carry out filling to foundry goods reinforcement position and thick heavy in section place, filling time is short, and temperature loss is little, porosity is little, achieve steady filling and the smooth transmission of pressure at each position of aluminium liquid, feeding a casting is effective, and total quality is high, ingate is easy to excision, and production efficiency is high.Apply this system, the extrusion casint loading time of short vehicle frame is short, efficiency is high, and temperature loss is little, and the porosity of product is few, and bearing mounting hole place shrinkage cavity defect is few, and ingate is easy to excision, and the total quality of foundry goods is better.
