Abstract
The present invention discloses a kind of casting method and mold with thin handle core model, overcomes the buoyancy of molten metal using the structure for erectting thin handle core model, avoids damaging at thin handle.Casting mould structure includes shell, and a plurality of runner of upper and lower directions is set in the shell, and the top that casting gate is arranged on mold is annular, setting riser among the casting gate, setting core model, the neck of the core model are abutted with fixed block among mold, and the fixed block is fixed on the inner casing of mold；It is link block above fixed block, the link block is bulge loop type, and top is abutted with casting gate, the centrally disposed riser of link block；The land area of the mold was the plane of medial axis.It is an advantage of the invention that：As a result of vertical structure, overcome caused by buoyancy to the torque at thin handle, ensure that workpiece quality.
Description
Technical field
The present invention relates to casting technology field, specifically a kind of casting mould.
Background technology
Casting mould with thin shank type core model, the prior art is usually using horizontal casting method, and this method is due to casting
During making, larger buoyancy is born at the thin handle of mold core, phenomenon of rupture often occurs, workpiece is caused to scrap；It further, since should
The both sides at place are respectively abdomen and the lower part of core model, and volume is larger, therefore, metal flow can be caused to be obstructed.
Invention content
In order to solve the above technical problems, the object of the present invention is to provide a kind of vertical casting method, specific technical solution is such as
Under：
A kind of casting method with thin handle core model overcomes the floating of molten metal using the structure for erectting thin handle core model
Power avoids damaging at thin handle；The a plurality of runner that upper and lower directions is set on the shell is further included, casting gate is arranged on the top of mold
For annular, casting gate centre setting riser；The neck of core model abuts the buoyancy to overcome core model with fixed block.
The mold includes shell, and a plurality of runner of upper and lower directions is set in the shell, and casting gate is arranged on mold
Top is annular, riser is set among the casting gate, mold centre setting core model, neck and the fixed block of the core model support
It connects, the fixed block is fixed on the inner casing of mold；Be link block above fixed block, the link block is bulge loop type, top with
Casting gate abuts, the centrally disposed riser of link block；The land area of the mold was the plane of medial axis.
It is an advantage of the invention that：As a result of vertical structure, overcome caused by buoyancy to the torque at thin handle, by this
Torque is converted into the pulling force of upward vertical direction；To prevent the pulling force from being damaged caused by core model, set on the top of core model
The fixed block abutted with the neck of core model, to prevent the structure pickup difficult, there is provided connecting block structure, in this way, the mold
It is a kind of assembling die, it is detachable after the completion of casting, convenient for pickup；The defects of to overcome poor fluidity, there is provided downwards
To runner, metal enters cavity below the mold, in this way, metal mold cavity is remained due to being influenced by runner temperature
Higher temperature ensures that shrinkage cavity phenomenon will not occur for final part.
Description of the drawings
Fig. 1 is the mold structure diagram of the present invention.
Specific embodiment
Illustrate the present invention below in conjunction with the accompanying drawings, as shown in Figure 1, the present invention using the structure for erectting thin handle core model come
Overcome the buoyancy of molten metal, avoid damaging at thin handle.
The mold includes shell 1, and a plurality of runner 3 of upper and lower directions is set in the shell 1, and casting gate 2 is arranged on mould
The top of tool is annular, setting riser 4 among the casting gate 2, setting core model 5 among mold, the neck 8 of the core model with it is solid
Determine block 7 to abut, the fixed block 7 is fixed on the inner casing 10 of mold；It is link block 11 above fixed block 7, the link block 11
For bulge loop type, top is abutted with casting gate, the centrally disposed riser of link block；The land area of the mold was medial axis
Plane 12.
The present invention overcomes at the thin handle of mold core 6 and bears larger torsion, will not be broken in casting process；By
It is larger that volume is put forward in the abdomen 5 of core model and the bottom 12 of core model, so, through-hole 13 is provided on core model convenient for gas circulation；
Through practice examining, design requirement is fully achieved in 9 mass of workpiece of the invention.
Claims (2)
1. a kind of casting method with thin handle core model, it is characterised in that：It is molten to overcome using the structure for erectting thin handle core model
