Abstract
Usual hood is whole to be made up of four parts, needs to coordinate its assembling, weld, and cost is high, long in time limit.The technical scheme that hood mould described in the utility model adopts is: this mould is divided into cavity side and core side, comprises cover half, dynamic model, running gate system, humidity control system, demolding structure and liftout attachment.Qian Mo Ban ﹑ hot runner manifold and top board are positioned at cavity side, and Hou Mo Ban ﹑ mould pin and base plate are positioned at core side, and design temperature regulating system on front template and rear pattern plate, cover half is provided with running gate system, dynamic model is provided with demolding structure, base plate is provided with liftout attachment.
Description
Technical field
The utility model relates to mould manufacturing field, is specifically related to hood mould manufacturing field.
Background technology
Usual hood is combined by body, installation buckle, acoustical cotton and car mark; Because whole hood is made up of four parts, this just needs after having produced product, and carry out assembling to it and coordinate, car mark and product ontology have welded, and so just increase assembly cost, extend the duration; And car mark normally electroplated product, need first injection moulding, carrying out plating surface treatment again, injection moulding and plating all need mould and tool, virtually add cost, and plating all exists pollution to environment and operator, the national producer to manufacture and regional requirements are more and more stricter, so improve the car mark reprocessing technique of this product.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the utility model provides a kind of hood mould, after product injection moulding completes, again surperficial thermoprint is carried out to product, reach the effect of plating, simplify Product Assembly process, reduce costs, the reduction of erection time, improve product size precision.
Hood mould described in the utility model; solving the technical scheme that its technical problem adopts is: this mould comprises cover half, dynamic model, running gate system, humidity control system, mould emptier and liftout attachment; Qian Mo Ban ﹑ hot runner manifold and top board are positioned at cavity side; Hou Mo Ban ﹑ mould pin and base plate are positioned at core side; front template and rear pattern plate are provided with humidity control system; cover half is provided with running gate system, dynamic model is provided with demolding structure, base plate is provided with liftout attachment.Cover half comprises the top board, hot runner manifold, front template, die cavity and the mold insert thereof that are linked in sequence; Dynamic model comprises the core and mold insert, rear pattern plate, mould pin, base plate that are linked in sequence; Demolding structure is arranged between rear pattern plate and mould pin; Cover half is that the die steel being NAK80 by material is made; Dynamic model material is that the die steel being P20 by material is made.
Hood material adopts PP-GF30, and shrinkage factor is 0.6%.PP-GF30 belongs to roving glass fiber PP, and fiber length distribution is even, and can form three-dimensional net structure, comprehensive mechanical property is strong; And material deformation is little, superior fatigue resistance, mobile performance are little, molded performance is good.
The utility model hood mould has following effect, greatly simplifies the follow-up assembly working of product, reduces production cost, improve production efficiency, shorten the production cycle, also improve dimensional accuracy and the stability of product simultaneously, obtain good Social and economic benef@.
Accompanying drawing explanation
Fig. 1 is the utility model hood mould exploded view
1. top board; 2. hot runner manifold; 3. front template; 4. rear pattern plate; 5. mould pin; 6. base plate; 7. liftout attachment; 8. demolding structure; 9. running gate system; 10. humidity control system.
Detailed description of the invention
1) hood product structure is adjusted, increase car mark structure, periphery R angle minimization, and reach the requirement meeting its function.
2) hood material adopts PP-GF30, and shrinkage factor is 0.6%.PP-GF30 belongs to roving glass fiber PP, and fiber length distribution is even, and can form three-dimensional net structure, comprehensive mechanical property is strong; And material deformation is little, superior fatigue resistance, mobile performance are little, molded performance is good;
3) MOLDFLOW analysis is carried out to product 3D data;
4) mould structure design is carried out according to the analysis result of product 3D data and MOLDFLOW;
5) mould structure design: carry out parting according to product 3D figure, be divided into cavity side and core side.Front template 3 ﹑ hot runner manifold 2 and top board 1 is increased in cavity side; Rear pattern plate 4 ﹑ mould pin 5 and base plate 6 is increased in core side.Design temperature regulating system 10 on front template 3 and rear pattern plate 4, cover half partial design running gate system 9, dynamic model partial design demolding structure 8, base plate 6 increases liftout attachment 7.
