Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding die technology, specifically to an automotive crossbeam molding die. Background Technology
[0002] Crossbeams not only ensure the torsional rigidity of the chassis and bear longitudinal loads, but also support the main components of the vehicle. Trucks typically have 5-6 crossbeams, and sometimes more. The structural features of side-beam chassis are that they facilitate the installation of the cab, cargo box, and some special equipment, as well as the arrangement of other assemblies. This is beneficial for modifying and developing various types of vehicles, and therefore they are widely used in trucks and most special vehicles. Stamping dies are required during the production of automotive crossbeams.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 In this embodiment, an automobile crossbeam forming mold includes a support frame 2 fixed on the upper surface of a base 1, a drive mechanism 3 on the upper surface of the support frame 2, a lower mold base 4 fixed on the upper surface of the base 1, and an ejection assembly 5 on the lower surface of the base 1.
[0026] In this embodiment, support feet are fixed at the four corners of the lower surface of the base 1.
[0027] Please see Figures 2 to 3In this embodiment, the drive mechanism 3 includes a first electric push rod 301 fixed to the upper surface of the support frame 2 by a fixing bracket. The outer side of the output shaft of the first electric push rod 301 slides through the support frame 2 and extends into the interior. An upper mold base 302 is fixed to the outer side of the output shaft of the first electric push rod 301. A protective frame 303 is slidably connected to the outer side of the upper mold base 302. Two fixing blocks 304 are fixed to the left and right side walls of the inner cavity of the support frame 2. Two sliding rods 305 are fixed to the opposite side of the upper and lower fixing blocks 304. Sliding cylinders 306 are slidably connected to the outer side of the left and right sliding rods 305. Connecting frames 307 are fixed to the opposite side of the left and right sliding cylinders 306. The bottom ends of the left and right connecting frames 307 are fixed to the left and right sides of the upper surface of the upper mold base 302 by bolts. An elastic component is provided on the top wall of the inner cavity of the left and right connecting frames 307. The gap between the protective frame 303 and the upper mold base 302 is adapted to allow the protective frame 303 to move linearly up and down on the outer side of the upper mold base 302.
[0028] Specifically, the elastic component includes spring telescopic rods 308 fixed to the top walls of the inner cavities of the left and right connecting frames 307. Mounting brackets 309 are fixed to the lower surfaces of the left and right spring telescopic rods 308. The opposite sides of the mounting brackets 309 are fixedly connected to the left and right sides of the upper mold base 302 by bolts. The spring telescopic rod 308 includes a first sliding rod, a second sliding rod is slidably connected inside the first sliding rod, and a spring is movably fitted on the outer side of the first sliding rod. The inner diameter of the slide cylinder 306 is adapted to the outer diameter of the slide rod 305. The first electric push rod 301 is located on the longitudinal central axis of the support frame 2. The lower mold base 4 and the upper mold base 302 are both existing technologies. The raw material can be pressed into shape through the mutual cooperation between the lower mold base 4 and the upper mold base 302.
[0029] It should be noted that the raw material is placed inside the upper surface of the lower die holder 4. Then, the first electric push rod 301 is activated. The output shaft of the first electric push rod 301 drives the upper die holder 302 and the protective frame 303 to move downward. Then, the protective frame 303 can cover the outer side of the upper die holder 302 and the lower die holder 4, improving the safety of stamping. When the protective frame 303 covers the outer side of the upper die holder 302 and the lower die holder 4, the spring telescopic rods 308 on the left and right sides are in a compressed state. At the same time, the lower surface of the protective frame 303 is in contact with the upper surface of the base 1. The raw material is pressed into shape through the joint cooperation of the upper die holder 302 and the lower die holder 4. After stamping is completed, the output shaft of the first electric push rod 301 is driven to move upward, driving the upper die holder 302 and the protective frame 303 to move upward. The first electric push rod 301 can drive the upper die holder 302 and the protective frame 303 at the same time, reducing the operating cost of the equipment.
[0030] Please see Figure 4In this embodiment, the ejection assembly 5 includes a second electric push rod 501 fixed to the lower surface of the base 1 by a fixing bracket. A top plate 502 is slidably connected inside the lower mold base 4. A sliding hole 503 is provided through the lower surface of both the lower mold base 4 and the base 1. The outer side of the output shaft of the second electric push rod 501 is slidably connected to the inside of the sliding hole 503. The outer side of the output shaft of the second electric push rod 501 is fixedly connected to the lower surface of the top plate 502.
[0031] Specifically, the top plate 502 moves linearly up and down on the upper surface of the lower mold base 4.
[0032] It should be noted that starting the second electric push rod 501 can drive the top plate 502 to move upward inside the lower mold base 4, which can eject the pressed workpiece and improve the convenience of material removal. By sliding the left and right side slide cylinders 306 up and down on the outside of the left and right side slide rods 305, the stability of the upper mold base 302 moving downward can be improved.
[0033] The working principle of the above embodiments is as follows:
[0034] In use, the raw material is placed inside the upper surface of the lower die holder 4. Then, the first electric push rod 301 is activated. The output shaft of the first electric push rod 301 drives the upper die holder 302 and the protective frame 303 to move downward. The protective frame 303 then covers the outer sides of the upper die holder 302 and the lower die holder 4, improving the safety of the stamping process. When the protective frame 303 covers the outer sides of the upper die holder 302 and the lower die holder 4, the left and right spring telescopic rods 308 are in a compressed state. Simultaneously, the lower surface of the protective frame 303 is in contact with the upper surface of the base 1. The upper die holder 302 and the lower die holder 4 work together to press the raw material into shape. After the stamping is completed, the first electric push rod 301 is driven to move upward through the output axis, which drives the upper die holder 302 and the protective frame 303 to move upward. Then the second electric push rod 501 is started, which can drive the top plate 502 to move upward inside the lower die holder 4, which can eject the pressed workpiece and improve the convenience of material removal. The upper die holder 302 can be improved by sliding up and down on the outside of the left and right sliding rods 305 through the left and right sliding cylinders 306.
