Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing design structure is fixed, which cannot be applied to the manufacture of auto parts with complex shapes and surfaces, and the water cooling structure mostly adopts straight pipes, which cannot fit complex horizontal surfaces, resulting in unbalanced local temperature distribution and poor cooling effect. , a conformal water-cooled mold for indirect thermoforming production line is proposed because of the problem that the temperature of the fillet part is too high

Embodiment 1

[0023] see Figure 1-3 , a conformal water-cooled mold used in an indirect thermoforming production line, comprising an upper die base plate 1 and a lower die base plate 6, an upper die mounting plate 2 is fixedly connected to the bottom surface of the upper die base plate 1, and the bottom surface of the upper die mounting plate 2 A thermoforming upper die 3 is connected to the upper part; a lower die mounting plate 5 is fixedly connected to the top surface of the bottom plate 6 of the lower die, and a thermoforming lower die 4 is connected to the top surface of the lower die mounting plate 5. According to the shape characteristics of the thermoforming parts, the The thermoforming upper die 3 is set as a concave die, and the thermoforming lower die 4 is set as a convex die; an upper die mounting cavity is arranged between the upper die base plate 1 and the upper die mounting plate 2, and the lower die base plate 6 and the lower die mounting plate 5 A lower mold installation c...

Embodiment 2

[0030] see Figure 1-3 , based on Embodiment 1, the difference is that;

[0031] The main equipment of the indirect thermoforming process includes: cold stamping line, automatic handling system, thermoforming press, heating furnace, and water-cooled mold.

[0032] In the production line, the blanking, preforming, trimming and punching of the sheet are first completed on the ordinary cold stamping line, and then coated with high-temperature anti-oxidant, placed in the heating furnace by the manipulator to complete the austenitization of the material, and then passed through The manipulator is quickly placed on the thermoforming mold fixed with the press for forming. After forming, it is cleaned and oiled for storage.

[0033] Such as figure 1 As shown, the upper mold bottom plate 1 is fixed to the upper worktable of the thermoforming press with a standard T-shaped slot by bolts, and the lower mold bottom plate 6 is fixed to the lower worktable of the thermoforming press. Take ...

Abstract

The invention discloses a conformal water-cooling mold for an indirect thermal forming production line, and belongs to the technical field of thermal forming modules. The conformal water-cooling mold for the indirect thermal forming production line comprises an upper mold bottom plate and a lower mold bottom plate, an upper mold mounting plate is fixedly connected to the bottom surface of the upper mold bottom plate, and a thermal forming upper mold is connected to the bottom surface of the upper mold mounting plate; a lower die mounting plate is fixedly connected to the top surface of the lower mold bottom plate, and a thermal forming lower mold is connected to the top surface of the lower mold mounting plate; a mounting cavity is formed between the bottom plate and the mounting plate, and a cooling water connecting device is mounted in the mounting cavity. The problems that an existing design structure is fixed and cannot be suitable for manufacturing work of automobile parts with complex profiles, and a water cooling structure mostly adopts a straight pipeline and cannot be attached to a complex transverse plane, so that local temperature distribution is unbalanced, the cooling effect is poor, and the temperature of a fillet part is too high are effectively solved.

Description

technical field [0001] The invention relates to the technical field of thermoforming modules, in particular to a conformal water-cooling mold used in an indirect thermoforming production line. Background technique [0002] At present, the automobile industry is pursuing the lightweight of the car body under the environment of high efficiency, energy saving and safety. Therefore, more parts such as front and rear bumpers, door sills, and door anti-collision beams on cars use high-strength steel plates as raw materials. After the tensile strength of high-strength steel with a ferrite-pearlite microstructure reaches 1500MPa, if the stamping method is used, there will be problems such as stamping springback and poor formability, so only the thermoforming process can be used. The essence of the hot forming process is: heating the workpiece to austenite temperature and keeping it warm until the material is completely austenitized, and then quenching and cooling at a certain cooli...
