Abstract

The utility model discloses a novel components of a whole that can function independently on mode structure, including last die body and upper die base, go up die body and upper die base and pass through the fastener connection, go up the die body and be equipped with the die cavity face, being close to the 10mm scope of die cavity face and milling processing 0.2mm zanjon groove, do all the other positions of die cavity face mill processing 0.5 the slot that 1mm is dark. The beneficial effect of the utility model: save the mould core vent, reduce die cost. Increase the exhaust reliability, make casting quality more stable. When the exhaust was become invalid, its maintenance cost can greatly reduced.

Description

A kind of new split upper die structure

Technical field

The utility model is related to low pressure wheel hub casting mould technical field, mould knot in more particularly, to a kind of new split Structure.

Background technology

Statement in this part merely provides the background information relevant with the utility model disclosure thereby increases and it is possible to not Constitute prior art.

With the further maturation of hub mold industry, increasingly fierce, the raising die quality fall of each mould producer competition Low production cost has become the direction that each producer is constantly pursued.

On traditional upper die structure such as Fig. 1, mould 1 is overall structure, in order that the gas needs in die cavity are discharged at top as early as possible Process more than ten to tens exhaust consents 2 not waited at wheel rim position, and the venting plug 3 of equivalent amount to be pressed into, venting plug Also need to line the complicated technology such as cut and process, and this structure can lead to venting plug inner clip with the lengthening of use time Aluminium, leads to exhaust to be lost efficacy, and needs all to change, relatively costly.

Therefore prior art has much room for improvement and develops.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of reduction die cost, improves the new of casting quality Split upper die structure.

Technical solution of the present utility model is: a kind of new split upper die structure, including upper die body and upper bolster, Upper die body and upper bolster are connected by securing member, and upper die body is provided with cavity surface；10mm scope Milling Machining 0.2mm near cavity surface Deep trench, the deep groove of remaining position of cavity surface Milling Machining 0.5-1mm.

Described securing member is screw or bolt.

The thermal conductivity of upper bolster is more than the thermal conductivity of upper die body.

The beneficial effects of the utility model:

1st, save parting line venting plug, reduce die cost.

2nd, increase exhaust reliability, make casting quality more stable.

3rd, when exhaust was lost efficacy, its maintenance cost can substantially reduce.

4th, pass through to accelerate the solidification at foundry goods wheel rim position from the upper bolster material of high heat conduction, improve casting quality and property Energy.

Specific embodiment

Embodiment: refering to Fig. 2 to Fig. 3, the utility model is a kind of new split upper die structure, and this new construction is will be upper Mould upper mould of the prior art is divided into upper die body 4 and upper bolster 5 at wheel rim position separately as Fig. 2, and with screw or other Securing member is fixed.Wherein upper bolster 5 can go to imitate with the fast quickly cooling reaching foundry goods wheel rim position from the higher material of thermal conductivity Really, concrete exhaust structure is that remaining is near type at upper die body 4 top in addition to not processing around the screw hole being connected with upper bolster 5 The 10mm scope Milling Machining 0.2mm of Cavity surface is deep, and remaining position Milling Machining 0.5-1mm is deep, when upper die body 4 and upper bolster 5 assembling, Connected with screw 6 it is ensured that being fitted with upper bolster 5 in the face around screw hole, gap is left, to reach province in remaining Milling Machining face Remove venting plug come the purpose to be vented.Even if being also advantageous in that of this structure causes exhaust portion during long-term use simultaneously The folder aluminium of position it is also possible to after machine under mould the connecting screw 6 by unclamping upper die body 4 and upper bolster 5 quickly remove exhaust Aluminium skimmings in passage, to recover its exhaust effect.Improve further, may be omitted with the operation of upper die body 4 number milling exhaust passage, With the structure crossing Fig. 3, it is less than the binding face of upper bolster in Vehicle Processing operation and according to control vehicle, pads during die assembly The pad entering and needing gap condition of equivalent thickness, reaches its vented mould, the manufacturing procedure of mould so can be made more simple.

Advantage one: in wheel rim top portion, traditional upper die structure is divided into two, is vented using two split connecting portions, To save the exhaust plug structure of traditional backform.Advantage two: crowd does known, and the wheel rim top of wheel hub is thick big, for the one of whole foundry goods , easily casting flaw in individual heat energy-saving position, and two splits of this structure can select two kinds of different materials, by portion above Highly heat-conductive material is selected in position, and following position is led to hot material from low, can be to the wheel rim of foundry goods so when filling type and completing Top is quickly cooled down, to reduce the casting flaw at this position.

In the description of this specification, the description of term " embodiment " etc. means with reference to this embodiment or example description Specific features, structure, material or feature be contained at least one embodiment of the present utility model or example.In this specification In, identical embodiment or example are not necessarily referring to the schematic representation of above-mentioned term.And, the specific features of description, Structure, material or feature can combine in any one or more embodiments or example in an appropriate manner.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for this For the technical staff in field, the utility model can have various modifications and variations.All of the present utility model spirit and principle Within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
