Abstract

The utility model discloses a heat protection shield molding die. The heat protection shield molding die comprises an upper template and a lower template, wherein a male die is fixed on the upper template while a female die is fixed on the lower template; the shape of the female die matches with the shape of the male die; a sticking gap between the male die and the female die is 8%-12% of the thickness of a processed plate between the male die and the female die. The heat protection shield molding die can be used for stamping and stretching a relatively thin processed plate into a relatively thin heat protection shield, the reject ratio of the produced relatively thin heat protection shield is low, and the produced relatively thin heat protection shield can reduce air secondary pollution caused by an automobile engine.

Description

The heat shield mould
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of heat shield mould of automobile engine.
Background technology
The workpiece punching stretch that common automobile engine heat shield mould is normally 0.6mm thickness with thickness of slab forms heat shield, the heat shield radiating effect that this 0.6mm is thick is bad, therefore can not keep the waste gas of automobile engine discharge in temperature constant state, thereby inevitably, the car engine chance is discharged more secondary pollution air; And, the workpiece that common heat shield mould can not be thinner for the punching stretch thickness of slab, because thickness of slab is little than the amount of plastic deformation of thin workpiece, easily fracture, and also the product fraction defective is high.
The utility model content
The purpose of this utility model is to provide a kind of heat shield mould, can be used for the workpiece that the punching stretch thickness of slab is thinner and forms the thinner heat shield of thickness of slab, has solved the problem of product fraction defective height and more secondary pollution air.
For achieving the above object, the utility model provides a kind of heat shield mould, comprise cope match-plate pattern and lower bolster, be fixed with punch on described cope match-plate pattern, be fixed with die on described lower bolster, the shape of described die and described punch is complementary, the 8%-12% that the gap of fitting between described punch and described die is the workpiece thickness of slab between described punch and described die.
Preferably, the shape on described punch and described die surface is S type curved surface shape.
Compared with prior art, the 8%-12% that heat shield mould of the present utility model is the workpiece thickness of slab between described punch and described die due to the gap of fitting between described punch and described die, thereby workpiece that can be thinner for the punching stretch thickness of slab forms the thinner heat shield of thickness of slab, and be not easy fracture, the product fraction defective is low; And the heat shield that thickness of slab is thinner can keep the waste gas of automobile engine discharge in temperature constant state, thereby reduces the secondary pollution air that automobile engine is discharged.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are for explaining embodiment of the present utility model.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is the utility model heat shield mould.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similar element numbers represents similar element.
Please refer to Fig. 1, described heat shield mould comprises cope match-plate pattern 1 and lower bolster 2, be fixed with punch 3 on described cope match-plate pattern 1, be fixed with die 4 on described lower bolster 2, described punch 3 is complementary with the shape of described die 4, and described punch 3 is S type curved surface shape with the shape on described die 4 surfaces.The 8%-12% that between described punch 3 and described die 4, the gap of laminating is the workpiece thickness of slab between described punch 3 and described die 4, thereby workpiece that can punching stretch 0.15mm thickness forms the heat shield of thinner thickness, not only reduced material cost, and the heat shield process be not easy the fracture, the product fraction defective is low; And, the heat shield good heat dissipation effect of this minimal thickness, thus can keep waste gas that automobile engine discharges in temperature constant state, thus reduce the secondary pollution air that automobile engine is discharged.
Abovely in conjunction with most preferred embodiment, the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains the various modifications of carrying out according to essence of the present utility model, equivalent combinations.

Claims (2)

1. a heat shield mould, comprise cope match-plate pattern and lower bolster, be fixed with punch on described cope match-plate pattern, be fixed with die on described lower bolster, the shape of described die and described punch is complementary, and it is characterized in that: the 8%-12% that the gap of fitting between described punch and described die is the workpiece thickness of slab between described punch and described die.
2. heat shield mould as claimed in claim 1, it is characterized in that: the shape on described punch and described die surface is S type curved surface shape.
