Abstract

The invention relates to a water-cooled magnesium alloy casting die, which comprises a casting upper die, a casting lower die, a loose piece plug and cooling water. When several castings are cast, the crystallization forming speed and crystallization forming quality of the castings are influenced due to overhigh temperature of the die, cold water is injected into the die, hot water flows out of a water outlet at the other end, and the die is cooled quickly and forcibly, so that the required temperature of the casting die is achieved, production efficiency is improved, and the requirement on the inner quality of the castings is met.

Description

Water-cooled magnesium alloy cast mould

Technical field

The present invention relates to the magnesium alloy cast mould, particularly a kind of recirculated water cooling mould.

Background technology

At present, products such as magnesium alloy extruding, machine components stock, sacrificial anode product, its first procedure all is the cast magnesium alloy stock, and then carries out the product that is processed into of various procedure technologies, and the casting die of magnesium alloy stock moulding now has sand mould, metal die, resin sandbox, these moulding process have its advantage, simultaneously shortcoming is arranged also, show as mainly that material is loose, fine and close character is poor, clear partially, qualification rate is low, its reason is, cooling is slow, due to crystallization time is long.

Summary of the invention

At the deficiency of existing magnesium alloy stock foundry engieering, the invention provides a kind of water cooling casting mould of fast cooling moulding.

Water-cooled magnesium alloy cast mould comprises upper mould, lower mould, and mould is built up full die up and down, and upper and lower mould respectively has into water, water outlet pore.

Described water-cooled mould, its structure is: the periphery of metal casting die cavity is welded the layer of metal plate again, the space is left in the centre, so that appearance water, when die horizontal is placed, one end has inlet opening 2,11, and installation water pipe head, have apopore 8,15 at the other end, and water pipe is installed is connected mould and bed die and draw a circle to approve with patrix and be connected by the latching 9 die sinking handle 1 that is rotationally connected, last cast gate 10 is fixedlyed connected with the submarine gate 16, be placed on jointly on the cast gate bearing 17, water inlet pipe 2,11, outlet pipe 8,15 are welded on up and down on the mould, and plug 7 flexibly connects with mould up and down.

Described water-cooled mould can be that single counterdie constitutes mould, uses as the casting sacrificial anode; Also can be mould of the synthetic formation of upper and lower mould, use as casting extruding embryo material.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, water-cooled magnesium alloy cast mould comprises mold, bed die, two ends loose piece plug; Or single bed die, two ends loose piece plug.

Mould up and down, the loose piece plug constitutes a secondary mould, the loose piece plug that preheating is good is put into the position that the good bed die of preheating is set earlier, again that preheating is good mold closes and is fixing, the magnesium alloy liquid that fusing is good pours into, wait to solidify when reaching requirement, open mould by lifting on the die sinking handle 1, take out foundry goods, repeat said process, after 2～3 of castings, mold temperature is too high, when having influence on the foundry goods curing rate, feed running water and force to the mould cooling, according to the cooling rate of foundry goods crystallization solidifying requirements, regulate confluent by the valve openings size, to guarantee to reach best crystallization temperature requirement.

During as the cast magnesium alloy sacrificial anode, constitute a full die with a bed die, two loose piece plugs, at this moment the loose piece plug that preheating is good is put into the setting position of the good mould of preheating earlier, and fixes, begin cast, wait to solidify when reaching requirement, take out foundry goods, repeat said process, when mold temperature is too high, connect running water and progressively open valve, regulate confluent by the cooling requirement, so that reach best crystallization temperature requirement.

Use water cooling, regulate the temperature of mould, the application practice by in recent years proves, reached raising output, improve the quality, thinning microstructure, crystallization is even, compactness is good purpose, be a kind of casting method with extensive use, also can on aluminium alloy, be applicable.

Claims

1. water-cooled magnesium alloy cast mould, it is characterized in that comprising mold, bed die, die sinking handle, loose piece plug, cast gate, or bed die, loose piece plug, upper and lower mould has the water pipe of access, outlet pipe, regulates confluent, regulates mold temperature and reach the requirement of foundry goods optimum temperature.

2. water-cooled magnesium alloy cast mould as claimed in claim 1, it is characterized in that, affiliated mold, bed die, the periphery that is included in the foundry goods metal mold cavity is welded the layer of metal plate again, stay the gap between plate and the die cavity, horizontal two ends are left entry pore, water outlet pore respectively.

3. water-cooled magnesium alloy cast mould as claimed in claim 1 is characterized in that described loose piece plug, is included as the convenient anode casting of placing the hole slot that the connection chipware is opened on the loose piece plug is installed.
