Abstract
The utility model provides a cavity of a differential support squeeze casting die, and relates to cavities of squeeze casting dies and the cavity is used for solving the problems that the differential supports manufactured by the existing dies have poor internal quality, low internal and surface hardness and poor mechanical properties and can not be industrialized. The cavity is put in the die plate of the die and comprises a sprue gate sleeve. The cavity is also provided with a main runner and an auxiliary runner, wherein one end of the main runner is communicated with the top of the sprue gate sleeve and the other end of the main runner is communicated with one die cavity of a product; and one end of the auxiliary runner is communicated with the side wall of the sprue gate sleeve and the other end of the auxiliary runner is communicated with the other die cavity of the product. The cavity is used for manufacturing differential supports.
Description
Technical field
The utility model relates to a kind of die cavity of squeeze casting mould.
Background technology
At present, the differential mechanism support is to adopt the methods such as aluminum alloy metal-type gravitational casting, compression casting, forging to produce.Yet the engine mounting dottle pin internal soundness that aluminum alloy gravity casting and pressure casting method are produced is poor and case hardness is not high, poor mechanical property; Can meet internal soundness requirement and performance requirement although forge, the following process amount is large, and cost is high; Liquid forging is a kind of more welcome method, and adopts the liquid forging of hydraulic press to produce right differential mechanism support, its production process complexity, and the production cycle of product is long, can't meet the demand of production in enormous quantities.Extrusion casint is between die casting and the novel green manufacturing technology of the low cost between forging, high-performance, near-net-shape.Be applicable to high-performance, wear-resisting, sealing, high pressure and complex-shaped aluminium alloy bearing member.But fill the type mode, adopt single running channel to fill type more, poor for complex-shaped part feeding capacity, and also in the transmittance process of pressure, the pressure loss is larger.
The utility model content
The purpose of this utility model is to provide a kind of die cavity of differential mechanism support squeeze casting mould, and the hardness poor, inner and surperficial with the internal soundness that solves the differential mechanism support that existing mold manufactures is not high, poor mechanical property and problem that can not industrialization.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: die cavity is placed in the template of mould, comprise the material sprue bush, die cavity also is provided with main running channel and auxiliary pouring channel, one end of main running channel is communicated with the top of sprue bush, the other end of main running channel is communicated with a die cavity of product, one end of auxiliary pouring channel is communicated with the sidewall of sprue bush, and the other end of auxiliary pouring channel is communicated with another die cavity of product.
The utlity model has following beneficial effect: the utility model has been broken through the thought that the single running channel of traditional indirect extrusion casting or compression casting is poured into a mould easy moulding, design by auxiliary pouring channel is carried more aluminium material to the thick position of part roof, and can better transmission of pressure, make the part end obtain better feeding, greatly reduce or eliminated the crackle shrink produced because of molten metal.
The accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, the die cavity of present embodiment is placed in the template 1 of mould, comprise material sprue bush 3, die cavity also is provided with main running channel 4 and auxiliary pouring channel 5, one end of main running channel 4 is communicated with the top of sprue bush 3, the other end of main running channel 4 is communicated with a die cavity of product, and an end of auxiliary pouring channel 5 is communicated with the sidewall of sprue bush 3, and the other end of auxiliary pouring channel 5 is communicated with another die cavity of product 9.。
The specific embodiment two: present embodiment is described in conjunction with Fig. 1, more than the internal diameter of the sprue bush 3 of present embodiment is greater than drift size 5mm, broken through the thought that traditional drift and sprue bush 3 are complementary, sprue bush 3 sizes are greater than to the drift size, avoid the metal generation plasticity of having solidified around sprue bush 3 in cavity filling process, reduce the pressure loss of pressure in this process, make the transport of pressure greatly promote.Other embodiment is identical with the specific embodiment one.
Operation principle: sprue bush 1 position is connected with running channel; Match with drift in sprue bush 3 positions, more than the internal diameter size of sprue bush 3 is greater than drift internal diameter size 5mm; Match with barrel in sprue bush 3 positions.
Main running channel 4 is connected with the tangent place of product great circle, and auxiliary pouring channel 5 is connected with the afterbody wall thickness gap larger part of product.Dreg collecting slot 6 everywhere is set on product 9, and dreg collecting slot 6 is connected with the die cavity of product 9 respectively.Two dreg collecting slot 6 places on product 9 tops arrange exhaust duct 7, and exhaust duct 7 is connected with exhaust block 8.
Claims (2)
