Abstract
The invention discloses a die-casting process method for a sensitive element aluminum alloy support. Via the way of increasing reinforcing ribs, every two of a plurality of convex plates are connected, so that the structure of a product becomes a tridimensional and meshed structure from a plane and frame structure, and the forming rigidity of a blank is improved. The feeding scheme comprises center gating and periphery multi-point, so that the fluidity of a metal liquid is improved, the problem of the forming difficulty of a frame thin-wall product is resolved, the products are cooled at the same rate, the structure uniformity of the products is guaranteed, and the die-casting thermal stress deformation is reduced. Air discharge dusts are increased on a die by a few quantity of machining processes; in order to improve the structure uniformity, no air hole and quality stability of the product, the processing speed is controlled according to the die-casting temperature, the pressure and the environment temperature, so that the uniformity of the product is improved and the air hole is avoided. The die-casting process method for the sensitive element aluminum alloy support is simple in structure, reliable in work, high in production efficiency and low in manufacturing cost, so that the die-casting process method is suitable for mass production.
Description
Technical field
The present invention relates to a kind of appearance structure complicated, to the die-casting process method of the demanding sensing element aluminium alloy post of aluminium alloy castings institutional framework.
Background technology
The sensing element support is because characteristics such as its complex structures; The main at present sand casting+process for machining method that adopts, but because this product is responsive especially to the weight requirement, requirement of mechanical strength is high; The foundry goods interior tissue requires high-quality requirements such as even; The sand casting process is difficult to reach one type of foundry goods requirement of QJ standard, and for this reason, it is the problem that this field is directly faced that the research and development die-casting process method solves this product system problem always.But because this product surface roughness requires height, product structure is complicated, and mechanical processing process very easily is out of shape; And in the extrusion process of current employing; Owing to raise unreasonable structure, cause tissue odds even, the tendency of product pore is very big; Simultaneously influenced by process environments, product quality can't be guaranteed.
Summary of the invention
Unreasonable in order to overcome existing sensing element support product mold structure; Product pore tendency is big; Cause product quality to can not get guaranteeing that the present invention provides a kind of die-casting process method of sensing element aluminium alloy post, this mould product pore is few; Even tissue, and the mechanical processing process product is not yielding.
The technical solution adopted for the present invention to solve the technical problems is:
1, improve properties of product through design novel die realization die casting new technology, adopt following scheme:
Because product belongs to thin-walled, framework, many boss structures; With traditional blank design, very easily distortion can't adopt the die casting mode to realize; The reinforcement mode that increases is adopted in the blank design for this reason; With linking to each other in twos with reinforcement between many boss, make product form solid, network structure by plane, frame structure, improved the rigidity of blank moulding.
Feed solutions adopts trumpet assembly, multiple feed all around.This mode can solve the flowability of improving molten metal, and the difficult moulding problem of solution framework thin-wall product keeps the cooling velocity of product consistent in addition, has guaranteed that organizing of product is more even, has reduced the die casting thermal stress deformation.
2, on mould, increase air discharge duct, for improving the even tissue of product, pore-free; Quality stability is come the calculation control fltting speed according to cast temperature and pressure and environment temperature, so just can improve the uniformity of product; Avoid pore, reach the purpose that improves the quality.

The specific embodiment
The die-casting process method of a kind of sensing element aluminium alloy post of the present invention uses equipment to be the 14OT cold-chamber die casting machine, and accumulator is a piston type, and energy storage pressure is placed on 12-15MPa, and this technical process is as shown in Figure 1:
(1) melting of A380 aluminium, purification;
(2) the powerful releasing agent of spraying on the cavity body of mould surface;
(3) Control for Kiln Temperature is at 720-750 ℃;
(4) adjustment each mechanism of die casting machine and Pressure gauge, mould assembly is adjusted to 10.5-12MPa on the equipment, and the accumulator supercharging pressure is adjusted to 12-15MPa;
(5) die cast: matched moulds → matched moulds time-delay → injection → pressurize time-delay → injection release → matched moulds release → die sinking → remove rising head, repair under burr → inflow road processing.
Claims (4)
1. the die-casting process method of a sensing element aluminium alloy post is characterized in that following step:
