Abstract

The utility model relates to the automobile stamping die field, in particular to a forming die for a thermal shield of an engine. The forming die comprises a die set composed of an upper die plate, a lower die plate, a guide post, a guide sleeve and two die feet, and is characterized by further comprising a pressing plate, a first female die, a second female die, a male die and a stroke limiting block, wherein the pressing plate is used for fixing the die feet, the first female die and the second female die are fixed on the lower die plate and attached to each other, the male die is in a step shape, fixed on the upper die plate, and matches with the first female die and the second female die, and the stroke limiting block is arranged between the upper die plate and the lower die plate. The forming die for the thermal shield of the engine has the advantages that the female dies and the male die are in a step shape, the structure is simple, and the brake forming of blank pieces of the thermal shield of the engine can be achieved; and the female dies are fixed on the lower die plate through limiting screws and leaning keys, and the stable installation of the female dies is achieved.

Description

Engine heat shield shaping mould

Technical field

The utility model relates to automobile diel field, relates in particular to a kind of engine heat shield shaping mould.

Background technology

Many parts/parts of automobile are all processed by diel, are just processed by a series of moulds such as the engine heat shield, and wherein molding procedure is accomplished by engine heat shield shaping mould.The punch and the die of existing shaping mould (like bending die) are bigger, and under big stamping press effect, therefore the skew of occurrence positions easily needs corresponding positioner.The utility model will be referred to a kind of engine heat shield shaping mould that is used for brake forming, and this shaping mould has the unique punch and the structure of die, and has effective die positioner.

The utility model content

The purpose of the utility model is to overcome the problems referred to above, a kind of die and punch with step is provided, can makes die firmly be installed on the engine heat shield shaping mould on the lower bolster.

For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: engine heat shield shaping mould; Comprise the mould bases that constitutes by cope match-plate pattern, lower bolster, guide pillar, guide pin bushing and mould pin, it is characterized in that: also comprise the press plate of fixed die pin, first die close to each other that is fixed in lower bolster and second die, be fixed in cope match-plate pattern and the punch that matches with first die and second die, the stroke limit piece between cope match-plate pattern and lower bolster; Described punch is a step.

As the further improvement to the utility model, second die is fixed on the lower bolster through stop screw.

As the further improvement to the utility model, first die is near the key that leans on that inserts lower bolster.

As the further improvement to the utility model, the end of cope match-plate pattern and lower bolster is provided with hanger.

The operation principle of the utility model is: punch is a step, and the die that first die and second die constituted also is step, and die and punch cooperatively interact; Before punching press begins, place engine heat shield blank between punch and the die; The beginning punching press, punch moves down, and contacts the shape that simultaneously the engine heat shield blank between punch and the die is fashioned into punch and die contact portion with die, accomplishes brake forming.

The beneficial effect of the utility model: die and punch are step, and be simple in structure, and can realize the brake forming of engine heat shield blank; Die is fixed on the lower bolster through stop screw with by key, has realized the firm installation of die.

Description of drawings

Fig. 1 is the structure chart of the utility model;

Fig. 2 is the hanger position view of the utility model;

Wherein, 1 cope match-plate pattern, 2 guide pin bushings, 3 guide pillars, 4 lower bolsters, 5 mould pin, 6 press plates, 7 stroke limit pieces, 8 second dies, 9 first dies, 10 punch, 11 lean on key, 12 stop screws, 13 hangers.

The specific embodiment

Figure is the preferred embodiment of the utility model, below in conjunction with accompanying drawing the utility model is further described: wherein, and 1 cope match-plate pattern, 2 guide pin bushings; 3 guide pillars, 4 lower bolsters, 5 mould pin, 6 press plates; 7 stroke limit pieces, 8 second dies, 9 first dies, 10 punch; 11 lean on key, 12 stop screws, 13 hangers.

Fig. 1 is the structure chart of the utility model; Fig. 2 is the hanger position view of the utility model; The concrete structure and the operation principle of the utility model are described according to Fig. 1 and Fig. 2 below; Engine heat shield shaping mould; Comprise the mould bases that constitutes by cope match-plate pattern 1, lower bolster 4, guide pillar 3, guide pin bushing 2 and mould pin 5, it is characterized in that: also comprise the press plate 6 of fixed die pin 5, first die 9 close to each other that is fixed in lower bolster 4 and second die 8, be fixed in cope match-plate pattern 1 and the punch 10 that matches with first die 9 and second die 8, the stroke limit piece 7 between cope match-plate pattern 1 and lower bolster 4; Described punch 10 is a step; Second die 8 is fixed on the lower bolster 4 through stop screw 12; First die 9 leans on key 11 near what insert lower bolster 4; The end of cope match-plate pattern 1 and lower bolster 4 is provided with hanger 13.

Punch 10 is a step, and the die that first die 9 and second die 8 are constituted also is step, and die and punch 10 cooperatively interact; Before punching press begins, place engine heat shield blank between punch 10 and the die; The beginning punching press, punch 10 moves down, and contacts the shape that simultaneously the engine heat shield blank between punch 10 and the die is fashioned into punch 10 and die contact portion with die, accomplishes brake forming.

Second die 8 is fixed on the lower bolster 4 through stop screw 12; First die 9 leans on key 11 near what insert lower bolster 4; Insert the key 11 that leans on of lower bolster 4 and fix first die 9 from sidepiece; Thereby die firmly is installed on the lower bolster 4, also can prevents the lateral displacement of die simultaneously.

Stroke limit piece 7 between cope match-plate pattern 1 and the lower bolster 4 plays travel limit; When cope match-plate pattern 1 and punch 10 are descending; Stroke limit piece 7 is simultaneously descending, and it is narrow that stroke limit piece 7 stretches into an end of lower bolster 4, when stroke limit piece 7 goes downwards to a certain degree; The thick slightly part of stroke limit piece 7 touches lower bolster 4 upper surfaces, and is no longer descending.

As shown in Figure 2, the end of cope match-plate pattern 1 and lower bolster 4 is provided with hanger 13, and hanger 13 is done carrying and used.

The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
