Abstract
The utility model discloses an aluminum alloy wheel low-pressure casting die. The aluminum alloy wheel low-pressure casting die comprises a bottom die and a top die which is matched with the bottom die, and the bottom die comprises a bottom die body, a thermal insulation device which is arranged in a bottom cavity of the bottom die body and a cooling pipe which is arranged in the bottom cavity of the bottom die body and located on a spoke finish turning surface. According to the aluminum alloy wheel low-pressure casting die, the thermal insulation device is tiled on the bottom cavity, then the cooling pipe is disposed on the spoke finish turning surface, that is to say an inverted gradient position, so that solidifying patch-up and shrinkage effects can be relieved, and finally, the rejection rate caused by slight shrinkage porosity of a spoke machining face is reduced by 5%.
Description
Technical field
The utility model relates to technical field of mold, more particularly, relates to a kind of low-pressure casting die of aluminium alloy wheel.
Background technology
In aluminum-alloy wheel low pressure casting production process, casting solidification order is for first to solidify from cast gate position farthest, gate location final set; Spoke position is generally from the Feeding channel close to cast gate and is greater than from the Feeding channel away from cast gate, can realize so normal consecutive solidification.
Feeding is exactly when die casting filling has approached, by supercharging, the molten metal not solidifying is supplemented complete to the completely unsubstantial part of stowing operation medium casting.Generally can produce casting contracting wall thickness, thermal center, turning, place that casting section thickness transition is large etc. are local.
Be shaped to down the finish turning product of gradient for spoke, spoke position is less than from the Feeding channel away from cast gate from the Feeding channel close to cast gate, and when casting, sufficient feeding is failed to obtain from the aluminium liquid away from cast gate in spoke position, thereby occurs the micro-shrinkage porosite of spoke finish turning face.
Therefore, how to reduce spoke and be shaped to the micro-shrinkage defect of the finish turning of falling gradient product, become the current technical issues that need to address of those skilled in the art.
Utility model content
In view of this, the utility model provides a kind of low-pressure casting die of aluminium alloy wheel, is shaped to the micro-shrinkage defect of the finish turning of falling gradient product to reduce spoke.
For realizing the above object, the utility model provides following technical scheme:
A kind of low-pressure casting die of aluminium alloy wheel, the backform that comprises bed die and coordinate with described bed die;
Described bed die comprises:
Bed die body;
Be arranged at the attemperator in the bottom cavity of described bed die body;
Be arranged in the bottom cavity of described bed die body, and be positioned at the cooling tube of spoke finish turning face.
Preferably, in above-mentioned low-pressure casting die of aluminium alloy wheel, described attemperator is heat-preservation cotton.
Preferably, in above-mentioned low-pressure casting die of aluminium alloy wheel, described cooling tube has many cooling arms that are arranged in spoke finish turning face position.
Technical scheme from the above can be found out, the low-pressure casting die of aluminium alloy wheel that the utility model provides, attemperator is laid in after bottom cavity, cooling tube is placed in spoke finish turning face, namely in the position of falling gradient, alleviate and solidify feeding effect, finally make the percent defective causing due to the micro-shrinkage porosite of spoke machined surface reduce by 5%.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below by embodiment or prior art are retouched described in the accompanying drawing of required use be briefly described, apparently, the accompanying drawing of retouching below in described is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the bed die that Fig. 1 provides for the utility model embodiment.
The specific embodiment
The utility model discloses a kind of low-pressure casting die of aluminium alloy wheel, be shaped to the micro-shrinkage defect of the finish turning of falling gradient product to reduce spoke.
Below in conjunction with the accompanying drawing in the utility model embodiment, described in the technical scheme in the utility model embodiment is retouched clearly and completely, obviously, the described embodiment that retouches is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the structural representation of the bed die that Fig. 1 provides for the utility model embodiment.
The low-pressure casting die of aluminium alloy wheel that the utility model embodiment provides, the backform that comprises bed die and coordinate with described bed die.Improvement of the present utility model is bed die, below bed die is described in detail.
Described bed die comprises bed die body 101, attemperator 102 and cooling tube 103.
Wherein, the side with respect to die cavity of bed die body 101, the bottom of bed die body 101 offers bottom cavity.
The low-pressure casting die of aluminium alloy wheel that the utility model provides, attemperator 102 is laid in after bottom cavity, cooling tube 103 is placed in spoke finish turning face, namely in the position of falling gradient, alleviate and solidify feeding effect, finally make the percent defective causing due to the micro-shrinkage porosite of spoke machined surface reduce by 5%.
In the utility model one specific embodiment, described attemperator 102 is heat-preservation cotton.Described cooling tube 103 has many cooling arms that are arranged in spoke finish turning face position.
To the above explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
