Abstract
The present invention relates to a method of bimetal pressure casting, which belongs to the technical field of metal casting. The aim of the present invention is to provide a fine new method of producing bimetal products with a pressure casting technology. The present invention has the technical scheme that in the method of bimetal pressure casting, an injection cylinder and a pressure chamber are added on the existing pressure casting equipment, and a casting gate is added on a pressure casting mould. A set of mould depth positioning device is added on a movable mould of the pressure casting mould and used for controlling product size during two-time pressure casting, and thus, an alloy product is produced by two-time pressure casting. The present invention has the advantages that two kinds of alloy with different performance are compounded together with the technology method of bimetal pressure casting of the present invention so as to obtain the alloy pressure casting product. The alloy pressure-casting product integrates the advantages of two kinds of alloy and has wide application range.
Description
Technical field
The invention belongs to the metal casting technical field.
Background technology
The casting technique that carries out compound casting that has existed at present mainly is that equipment such as employing centrifugal casting, sand casting are simple, the casting technique of processing ease, does not also adopt the pressure casting process method to carry out compound casting both at home and abroad.
Summary of the invention
The purpose of this invention is to provide the method that a kind of brand-new employing pressure casting process is produced bimetallic product.
Technical scheme of the present invention is: Bimetal Press-casting Method, it is characterized in that: on existing die casting equipment, increase a shot sleeve and press the chamber, on die casting, increase a cast gate, on the dynamic model of described die casting, increase the size of mold depth localization device product when controlling twice die casting, produce alloy product by twice die casting, concrete steps are as follows:
1) gap of dynamic model die cavity and quiet model cavity is adjusted to the thickness of first kind of metal in the alloy product, it is indoor that first kind of metal joined first kind of metal crimp, starts first kind of metal of first kind of metal shot sleeve injection and go into mold cavity;
2) when first kind of metal forms the metal level of thin-walled in mold cavity after, the mold cavity degree of depth is adjusted to the size of final alloy product, it is indoor that second kind of metal joined second kind of metal crimp, starts second kind of metal of second kind of metal shot sleeve injection and go into mold cavity;
3) after the cooling, the alloy product of die casting is taken out in die sinking.
The invention has the beneficial effects as follows, utilize bimetallic die-casting process method of the present invention, two kinds of diverse alloys of performance can be combined with each other, obtain the alloy die cast product.This alloy die cast product combines the advantage of two kinds of alloys, applied range.
Description of drawings
Fig. 1 a is the state diagram of adopting after the die casting equipment injection for the first time of the method for the invention.
Fig. 1 b is the state diagram of adopting after the die casting equipment injection for the second time of the method for the invention.
Among the figure, 1. second kind of metal shot sleeve, 2. first kind of metal shot sleeve, 3. quiet mould, 4. dynamic model, 5. depth of cavity positional cylinder, 6. second kind of metal crimp chamber, 7. first kind of metal crimp chamber, 8. quiet model cavity, 9. dynamic model die cavity, the size of the final alloy product of H-, first kind of metal thickness of h-.
The specific embodiment
Below in conjunction with accompanying drawing invention is further specified.
Shown in Fig. 1 a and Fig. 1 b, on existing die casting equipment, increase a shot sleeve and press the chamber, on the quiet mould 3 of die casting, increase a cast gate, on the dynamic model 4 of described die casting, increase the size of mold depth localization device product when controlling twice die casting, produce alloy product by twice die casting, concrete steps are as follows:
1) adjusts die cavity depth localization cylinder 5, the dynamic model die cavity 9 and the gap of quiet model cavity 8 are adjusted to the thickness h of first kind of metal in the alloy product, first kind of metal joined in first kind of metal crimp chamber 7, start first kind of metal of first kind of metal shot sleeve 2 injection and go into mold cavity;
2) when first kind of metal forms the metal level of thin-walled in mold cavity after, adjust die cavity depth localization cylinder 5, make the size H that the dynamic model die cavity 9 and the gap of quiet model cavity 8 is adjusted to final alloy product, second kind of metal joined in second kind of metal crimp chamber 6, start second kind of metal of second kind of metal shot sleeve 1 injection and go into mold cavity;
3) after the cooling, the alloy product of die casting is taken out in die sinking.
Claims (1)
1. Bimetal Press-casting Method, it is characterized in that: on existing die casting equipment, increase a shot sleeve and press the chamber, on die casting, increase a cast gate, on the dynamic model of described die casting, increase the size of mold depth localization device product when controlling twice die casting, produce alloy product by twice die casting, concrete steps are as follows:
1) gap of dynamic model die cavity and quiet model cavity is adjusted to the thickness of first kind of metal in the alloy product, it is indoor that first kind of metal joined first kind of metal crimp, starts first kind of metal of first kind of metal shot sleeve injection and go into mold cavity;
2) when first kind of metal forms the metal level of thin-walled in mold cavity after, the mold cavity degree of depth is adjusted to the size of final alloy product, it is indoor that second kind of metal joined second kind of metal crimp, starts second kind of metal of second kind of metal shot sleeve injection and go into mold cavity;
3) after the cooling, the alloy product of die casting is taken out in die sinking.
