Abstract
The utility model discloses a drawing mold of a water falling groove of an automobile, comprising a concave mold and a convex mold, wherein a prepressing cavity with three-stage steps which become larger in sequence from the bottom to the top is arranged on the molded surface of the local area of the concave mold corresponding to the water falling groove of the automobile; and the prepressing cavity is internally provided with a prepressing device which comprises a bottom plate, a pair of gas springs, a plurality of limiting columns, a connecting plate, a plurality of buffering blocks and a combined block of a concave mold. The bottom plate is fixedly connected onto the step surface at the upper part of the prepressing cavity; the gas springs are fixed on the lower end surface of the bottom plate; the limiting columns are fixedly arranged on the lower end surface of the bottom plate in a manner of staggering from the gas springs; the connecting plate is placed on the step surface at the lower part of the prepressing cavity; the combined block of the concave mold is fixedly connected to the lower end surface of the connecting plate and can be movably arranged in a lower cavity of the pressing cavity, and the lower end surface of the combined block of the concave mold and the lower end surface of the concave mold form the molded surface of the water falling groove of the automobile together; and the buffering blocks are fixedly connected onto the step surface at the lower part of the prepressing cavity and are uniformly distributed at the periphery of the combined block of the concave mold.
Description
Technical field
The utility model relates to the drawing die of the drowning groove of a kind of automobile.
Background technology
Drowning groove 10 (see figure 1)s of automobile are the parts that can see after the automobile bonnet is opened, but the surface quality requirement of the groove that should fall into water is very high, and its surface quality requires to be equal to vehicle exterior cladding element.In actual production process, the stretch process mode of the drowning groove of the automobile of prior art makes the surface local zone 11 of part that fluctuating be arranged, the surface quality instability, and the difficult quality of product conforms to quality requirements, and therefore demands urgently improving.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the drawing die that provides a kind of automobile to fall into water groove, it does not change the agent structure of original mould, rational in infrastructure, simple effectively, expense is cheap.
The technical scheme that realizes above-mentioned purpose is: the fall into water drawing die of groove of a kind of automobile, comprise die and punch, and on falling into water the profile of regional area of groove, offers by the corresponding described automobile of described die the precompressed cavity of a two stage steps that increases successively from bottom to up; Be provided with a prepressing device in this precompressed cavity, this prepressing device comprises a base plate, a pair of air spring, some limited posts, a plate, some buffer stoppers and a cavity splits, wherein,
Described base plate is fixedly mounted on the upper stage terrace of described precompressed cavity;
Described a pair of air spring is fixedly mounted on the lower surface of described base plate;
Described some limited posts described a pair of air spring that staggers is fixedly mounted on the lower surface of described base plate;
Described connecting plate is placed on the lower stage terrace of described precompressed cavity;
Described cavity splits is fixedly connected on the lower surface of described connecting plate and places movably in the lower cavity of described precompressed cavity, the common profile that constitutes the drowning groove of described automobile in the lower surface of this cavity splits and the lower surface of described die;
Also be positioned at the periphery of described cavity splits on the lower stage terrace of the fixedly connected described precompressed cavity of described some buffer stoppers in uniform way.
The technical scheme of the drawing die of the drowning groove of automobile of the present utility model, employing is under the situation that does not change original drawing die agent structure, offer a precompressed cavity on the die and a prepressing device is being installed in this precompressed cavity, can in drawing process, carry out precompressed to guarantee this region surface quality by the local profile to the drowning groove of automobile.This mould structure rationally, simple effectively, expense is cheap, makes the automobile groove steady quality in actual production process that falls into water, conform to quality requirements.
Description of drawings
Fig. 1 is the structural representation of the drowning groove of automobile;
Fig. 2 is the cutaway view of the drawing die of the drowning groove of automobile of the present utility model.
The specific embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 2 and in conjunction with consulting Fig. 1, the fall into water drawing die of groove of automobile of the present utility model comprises die 7 and punch 8, offers the precompressed cavity of three grades of steps that increase successively from bottom to up on the corresponding automobile of die falls into water the profile of regional area of groove; Be provided with a prepressing device in this precompressed cavity, this prepressing device comprises a base plate 1, a pair of air spring 2, some limited posts 3, a plate 4, some buffer stoppers 5 and a cavity splits 6, wherein:
A pair of air spring 2 is fixedly mounted on the lower surface of base plate 1;
Some limited posts 3 a pair of air spring 2 that staggers is fixedly mounted on the lower surface of base plate 1;
Connecting plate 4 is placed on the lower stage terrace 72 of precompressed cavity;
Cavity splits 6 is fixedly connected on the lower surface of connecting plate 4 and places movably in the lower cavity 73 of precompressed cavity, and the lower surface of the lower surface of this cavity splits 6 and die 7 constitutes the profile of the drowning groove of automobile jointly;
Also be positioned at the periphery of cavity splits 6 on the lower stage terrace 72 of some buffer stopper 5 fixedly connected precompressed cavitys in uniform way.
The operation principle of the drawing die of the drowning groove of automobile of the present utility model is:
The blank of groove of earlier automobile being fallen into water is placed in the die cavity that forms between the upper surface of the lower surface of die 7 and punch 8, then starts press and begins to stretch; The blank of the drowning groove of automobile is in drawing process, when the blank of the drowning groove of automobile contacts with cavity splits 6, air spring 2 begins compression, make cavity splits 6 tightly push down the profile of the regional area of blank, prevent that this regional profile from producing uncontrollable distortion, at this moment the decrement of limited post 3 restriction air springs 2; After the drowning groove compacting of automobile was finished, die 7 beginnings were up, and base plate 1 is along with die 7 is up, and cavity splits 6 is slowly descending under the interaction of air spring 2 and buffer stopper 5, avoided because cavity splits 6 descending too fast surfaces to the drowning groove of automobile damage.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
