Abstract

The utility model relates to a casting mould for a sleeve of a shock absorber and belongs to the field of casting moulds. The existing mould has the defects that a local part is ofen not fully filled and production efficiency is low. The casting mould for the sleeve of the shock absorber comprises an upper mould and a lower mould, each of the upper mould and the lower mould is provided with two semi-mould cavities split along a central line, the semi-mould cavities on the upper mould correspond to the semi-mould cavities on the lower mould, two complete mould cavities can be formed after the upper mould and the lower mould are closed, one corresponding semi-pouring trough is respectively arranged between the two semi-mould cavities on the upper mould and between the two semi-mould cavities on the lower mould, a notch at the upper end of each semi-pouring trough is formed in the upper end face of the mould, and the lower end of each semi-casting trough is communicated with the bottom of each semi-mould cavity. The casting mould for the sleeve of the shock absorber realizes liquid feeding casting under liquid level, and two shock absorber blanks are cast at the same time by pouring once, and casting quality and production efficiency are effectively improved.

Description

A kind of dampener sleeve casting die

Technical field

The utility model belongs to the casting mould field, and is especially relevant with a kind of dampener sleeve casting die.

Background technology

Dampener sleeve is elongated tube shape component, adopts cast form.General damper casting die all is to comprise upper die and lower die, be respectively arranged with a half module groove of cutting apart along center line at upper die and lower die, upper die and lower die close, the two halves die cavity is combined into a complete die cavity, and when producing workpiece, die slot also tilts up, the molten metal of liquid state is poured into from the die cavity notch, after the cooling, separately upper die and lower die take out workpiece blank and enter fine finishining.Use such die casting, molten metal in the dies cavity and air contact area are big, the oxide skin area that produces is big, in casting cycle, make oxide skin sandwich foundry goods inside easily, and be up cooling successively from the bottom, be easy to generate the part at the labyrinth place and can not fill phenomenon, one time casting cycle can only be cast a workpiece, and production efficiency is low.

The utility model content

The purpose of this utility model is intended to solve uses existing mold to be easy to generate the defective that can not fill, once cast and can only cast a workpiece, provides a kind of once casting can cast a plurality of workpiece and can guarantee the dampener sleeve casting die that casting is full.

For this reason, the utility model is by the following technical solutions: a kind of dampener sleeve casting die, comprise upper die and lower die, all be provided with the half module groove of cutting apart along center line on the upper die and lower die, it is characterized in that: the half module groove quantity on the described upper die and lower die all is two, half module groove on the upper die and lower die is corresponding, upper die and lower die close, can be combined into two complete die cavitys, be provided with corresponding half pouring basin between two half module grooves of patrix and between two half module grooves of counterdie separately, this half pouring basin upper end notch is positioned at the mould upper surface, and lower end and described half module trench bottom connect.Behind the upper die and lower die that close, the workman directly pours into pouring basin with molten metal, and molten metal injects in the die cavity from bottom to top, realizes feed flow casting under the liquid, makes molten metal basic synchronization cooling up and down, prevents from can not fill owing to the bottom cooling part occurs soon.

Use the utility model can reach following beneficial effect: by two die cavitys being set in a secondary mould and being communicated with pouring basin bottom two die cavitys simultaneously, integral body when having realized casting is full to cast out two damper blanks simultaneously with once-cast, has effectively improved casting quality and production efficiency.
