Abstract

The utility model discloses a kind of casting mould with thin handle core, and the buoyancy of motlten metal is overcome using the structure for erectting thin handle core, it is to avoid damaged at thin handle.Casting mould structure includes being set in shell, the shell a plurality of runner of above-below direction, and the top that casting gate is arranged on mould is annular, the casting gate middle setting rising head, mould middle setting core, the neck of the core is abutted with fixed block, and the fixed block is fixed on the inner casing of mould；Fixed block top is contiguous block, and the contiguous block is bulge loop type, and top abuts with casting gate, the centrally disposed rising head of contiguous block；The land area of the mould was the plane of medial axis.The utility model has the advantages that：As a result of vertical structure, overcome that buoyancy causes to the moment of torsion at thin handle, it is ensured that workpiece quality.

Description

A kind of casting mould with thin handle core

Technical field

The utility model is related to casting technology field, specifically a kind of casting mould.

Background technology

Casting mould with thin shank type core, prior art usually uses horizontal casting method, and the method is due in casting During making, larger buoyancy is born at the thin handle of core rod, phenomenon of rupture often occurs, cause workpiece to scrap；Further, since should The both sides at place are respectively belly and the bottom of core, and volume is larger, therefore, metal flow can be caused to be obstructed.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a kind of vertical casting method, particular technique side Case is as follows：

A kind of casting method with thin handle core, the floating of motlten metal is overcome using the structure for erectting thin handle core Power, it is to avoid damaged at thin handle.

The a plurality of runner of above-below direction is set in a kind of casting mould with thin handle core, including shell, the shell, The top that casting gate is arranged on mould is annular, the casting gate middle setting rising head, mould middle setting core, the core Neck abutted with fixed block, the fixed block is fixed on the inner casing of mould；Fixed block top is contiguous block, the contiguous block It is bulge loop type, top abuts with casting gate, the centrally disposed rising head of contiguous block；The land area of the mould was medial axis Plane.

The utility model has the advantages that：As a result of vertical structure, overcome that buoyancy causes to the moment of torsion at thin handle, The moment of torsion is converted into the pulling force of upward vertical direction；It is the damage for preventing the pulling force from being caused to core, on the top of core There is provided the fixed block abutted with the neck of core, to prevent the structure pickup difficult, there is provided connecting block structure, so, should Mould is a kind of assembling die, detachable after the completion of casting, is easy to pickup；To overcome the defect of poor fluidity, there is provided to The runner in lower direction, metal from mould lower section enter die cavity, so, metal mold cavity due to being influenceed by runner temperature, all the time Keep temperature higher, it is ensured that final part will not occur shrinkage cavity phenomenon.

Brief description of the drawings

Fig. 1 is mould structure schematic diagram of the present utility model.

Specific embodiment

The utility model is illustrated below in conjunction with the accompanying drawings, as shown in figure 1, the utility model is used erectting thin handle core Structure overcome the buoyancy of motlten metal, it is to avoid damage at thin handle.

The mould includes being set in shell 1, the shell 1 a plurality of runner 3 of above-below direction, and casting gate 2 is arranged on mould The top of tool is annular, the middle setting rising head 4 of the casting gate 2, mould middle setting core 5, the neck 8 of the core with it is solid Determine block 7 to abut, the fixed block 7 is fixed on the inner casing 10 of mould；The top of fixed block 7 is contiguous block 11, the contiguous block 11 It is bulge loop type, top abuts with casting gate, the centrally disposed rising head of contiguous block；The land area of the mould was medial axis Plane 12.

The utility model overcomes at the thin handle of core rod 6 and bears larger torsion in casting process, will not break Split；Due to the belly 5 of core and the bottom 12 of core, to put forward volume larger, so, on core being provided with through hole 13 is easy to gas Circulation；Through practice examining, the mass of workpiece of the present utility model 9 is fully achieved design requirement.

Claims

1. a kind of casting mould with thin handle core, it is characterised in that：The mould includes being set in shell, the shell The a plurality of runner in lower direction, the top that casting gate is arranged on mould is annular, the casting gate middle setting rising head, in the middle of mould Core is set, and the neck of the core is abutted with fixed block, and the fixed block is fixed on the inner casing of mould；Fixed block top is Contiguous block, the contiguous block is bulge loop type, and top abuts with casting gate, the centrally disposed rising head of contiguous block；The conjunction of the mould Die face was the plane of medial axis.
