Abstract
The invention discloses an aluminum alloy hub casting die. The aluminum alloy hub casting die comprises an upper die body. The upper die body is provided with a sprue communicated with a die cavity. A sealing device is arranged on the sprue. An air inlet through hole is formed in the side wall of the sprue, and the air inlet through hole is communicated with a gas pressurizing system through an air pipe. According to the aluminum alloy hub casting die, the air inlet through hole is formed in the side wall of the sprue and communicated with the gas pressurizing system, a communication pipeline between the sprue and the gas pressurizing system is in the static state both in the working state and in the off-working state, and the situation that a pipe body is damaged due to the fact that a connection pipeline of the gas pressurizing system is pulled is avoided. A control valve is arranged at the upper end of the sprue, opening and closing of the sprue can be achieved at the first time through electric control, and daily production efficiency is improved. According to the scheme, the structure is simple, control is rapid, and the problems due to the fact that the sprue is not blocked completely, air leakage is caused, and unqualified products are produced are solved.
Description
Technical field
The present invention relates to automotive hub casting field, be specifically related to a kind of aluminum alloy hub casting die.
Background technology
The manufacture forming method of wheel hub comprises forging, plate forming, casting etc., and be wherein most widely used with casting, its cost is low, the scope of application is wide.Casting comprises gravitational casting, low pressure casting, counter-pressure casting and extrusion casint etc., the finished product tissue looseness of gravitational casting, mechanical property are poor, low pressure casting and counter-pressure casting high to equipment requirement, temperature difficulty controls, and extrusion casint cannot produce complicated workpiece.
For the problem of above-mentioned casting, the patent No. " 2007100273526 ", title " gas pressure casting device for aluminum alloy wheel and casting method thereof " propose solution, by pressurizeing in mould, make the crystallization under stress of aluminium liquid, thus make compact crystallization, and then improve mechanical property.But in this technical scheme rising head shutoff and to exert pressure in die cavity be all connect a hollow tube at oil cylinder or cylinder rod end, block or stopper are set on body again, the air admission hole be communicated with are set simultaneously on tube body wall realize with ambient atmos compression system.Because cylinder bar has upper and lower stroke, therefore efficiency is lower, meanwhile, because cylinder bar is upper and lower frequently, the connecting line of gas pressurization system is caused and pulls, connecting line is easily made to damage, and block or stopper and rising head are isolating construction, in conjunction with poorly sealed afterwards, mould intracavity gas easily leaks, cause pressure instability, product quality is affected.
Summary of the invention
The invention provides a kind of aluminum alloy hub casting die, not only can save time that rising head closes, increase work efficiency, and tight to rising head sealing, what can overcome that prior art causes gas pressurization system connecting line pulls simultaneously.
The present invention is achieved through the following technical solutions:
Aluminum alloy hub casting die, comprises patrix, and described patrix is provided with the rising head being communicated with die cavity, and described rising head is provided with closing device, and the sidewall of rising head is provided with air inlet through hole, and described air inlet through hole is communicated in gas pressurization system by tracheae.
Further improvement of the present invention scheme is, described closing device is be connected in pneumatic operated valve on rising head or oil pressure valve or manual rotary valve.
Further improvement of the present invention scheme is, described closing device comprises cylinder or oil cylinder, and the cylinder boom end of described cylinder or oil cylinder is fixed with shutoff plug or capping, and described cylinder is fixed on link, and described link and described patrix are connected.
Further improvement of the present invention scheme is, described shutoff plug or capping be positioned at described rising head top and with the upper shed fitted seal of rising head.
Further improvement of the present invention scheme is, described air inlet through hole is arranged on the sidewall of the rising head of closing device bottom.
Further improvement of the present invention scheme is, described tracheae is welded to connect the sidewall in rising head, and is communicated with air inlet through hole.
Further improvement of the present invention scheme is, the sidewall of the rising head of closing device bottom is provided with steam vent, and described steam vent is communicated with blast pipe.
The present invention compared with prior art has the following advantages:
The present invention establishes air inlet through hole on the sidewall of rising head, air inlet through hole is communicated with gas pressurization system, no matter be work or off working state, the connecting pipeline of rising head and gas pressurization system all remains static, and can not cause pull thus cause body to damage the connecting line of gas pressurization system.
Establish control valve in the upper end of rising head, by the automatically controlled keying that can realize rising head the very first time, improve the efficiency of daily production.This programme structure is simple, controls rapidly, avoids rising head shutoff sternly not cause the problem of leaking gas and causing product bad.
