Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a production mold for automobile parts. Background Art

[0002] In the automotive manufacturing industry, the production accuracy and efficiency of parts are one of the important indicators to measure the manufacturing level. Among them, stamping is a key process in the manufacture of automotive parts, and the design and manufacture of its molds are directly related to the final quality and production efficiency of the parts.

[0003] For stamping dies for arc-shaped parts, the core forming end is designed to be in an arc shape. When the profile is placed in the die, the contact area between the profile and the die is relatively small, and the contact surface is a curved surface, which makes it difficult to place the profile on the die effectively and stably. The unstable placement state not only increases the difficulty of operation, but also easily causes the profile to shift or shake during the stamping process, thereby affecting the accuracy and effect of the stamping forming; at the same time, due to the inaccurate placement of the profile, the fit between the die and the profile is reduced, and the pressure generated during the stamping process is unevenly distributed, further aggravating the fluctuation of the part molding quality, which will not only lead to quality problems such as part size deviation and shape distortion, but also reduce the yield rate and increase production costs.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown together, this embodiment provides an automobile parts production mold, which includes a lower mold base 1 and an upper mold base 2. A material matching component 4 is installed on the top of the lower mold base 1. Both sides of the top of the upper mold base 2 are provided with slideways 22 for the movable end of the material matching component 4 to pass through. Clamping blocks 5 are fixed to the opposite surfaces of the two movable ends of the material matching component 4. Block grooves 12 are provided on both sides of the top of the lower mold base 1 and directly below the clamping blocks 5.

[0026] The front and rear positions on both sides of the top of the lower mold base 1 are inlaid with lifting components 3, and the front and rear lifting components 3 are placed in a relative state. The movable ends of the lifting components 3 are fixedly connected with the mounting bars 6, and the profiles are placed between the tops of the four mounting bars 6.

[0027] The four mounting strips 6 are used to limit the front and rear end surfaces of the profile, and the two clamping blocks 5 are used to limit the sides of the profile, that is, positioning is achieved from the four sides of the profile, and the profile is limited to the middle of the mold core. Under the setting of the spring 33, it is ensured that the profile descends synchronously with the descent of the upper mold base 2 and contacts the mold core, thereby improving the stability, accuracy and fit of the profile placement, improving the precision and effect of stamping, and thus improving the yield rate of the finished product. In addition, it is also convenient to place the profile on the mold for stamping processing, thereby improving work efficiency.

[0028] like Figure 1 As shown, in this embodiment, positioning rods 21 are installed at the four corners of the bottom of the upper mold base 2, and positioning holes 11 are coaxially opened at the four corners of the top of the lower mold base 1 and located directly below the positioning rods 21.

[0029] like Figure 3 to Figure 4 As shown together, in the present embodiment, the material lifting assembly 3 includes a vertical bin 31, and smooth rods 34 are installed on both sides inside the vertical bin 31, and a T-block 35 is slidably installed between the two smooth rods 34, and the mounting strip 6 is fixed on the protruding end of the T-block 35. Sliding holes for the smooth rods 34 to pass through are provided on both sides of the top of the T-block 35, and a spring 33 is sleeved on the smooth rod 34 and located below the T-block 35. An inlet and outlet 32 ​​for the protruding end of the T-block 35 to pass through is provided on the side of the vertical bin 31 close to the mounting strip 6. When the profile is completely detached from the mounting strip 6, the compression of the spring 33 is released, and the mounting strip 6 is automatically reset upward under the resetting action of the spring 33.

[0030] like Figure 4 As shown, in this embodiment, a curved edge 61 is provided on the side of the mounting strip 6 away from the T-block 35. When the profile contacts the mold core for forming, the edge of the profile gradually separates from the top of the mounting strip 6. The setting of the curved edge 61 is more conducive to the profile falling off the mounting strip 6, making it smoother when offset. A retaining strip 36 is fixed to the top of the mounting strip 6 and close to the side of the T-block 35. The retaining strip 36 will also block the side of the profile to ensure that the front and rear edges of the profile are accurately positioned.

[0031] like Figure 1 to Figure 2As shown together, in this embodiment, the material assembly 4 includes two translation bars 43 that are respectively limited and slid inside the slideways 22 on both sides, and an electric telescopic rod 41 installed in the middle of the top of the upper mold base 2, and the clamping block 5 is fixed at one end of the translation bar 43 close to the lower mold base 1, and the movable end of the electric telescopic rod 41 is fixedly connected with a lifting bar 42, and a push-pull bar 45 is hingedly installed between the lifting bar 42 and the translation bar 43. When the profile is located between the clamping blocks 5 on both sides, the electric telescopic rod 41 is extended to drive the lifting bar 42 to move upward. Under the transmission action of the push-pull bar 45, the two translation bars 43 are pulled toward the center, that is, the profile is clamped between the clamping blocks 5 on both sides, so that the clamping blocks 5 are positioned and aligned to the center point, the four mounting bars 6 are limited from the front and rear end surfaces of the profile, and the two clamping blocks 5 are limited from both sides of the profile, that is, positioning is achieved from the four sides of the profile, and the profile is limited to the middle of the mold core.

[0032] like Figure 1 to Figure 2 As shown together, in this embodiment, a guide rod 44 is fixed inside the slideway 22, a sliding hole for the guide rod 44 to pass through is opened on one side of the translation bar 43, and the translation bar 43 is slidably connected to the guide rod 44 through the sliding hole.

[0033] like Figure 2 As shown, in this embodiment, both sides of the top of the lifting bar 42 are rotatably mounted with mounting shaft 1 46 through bearings, the side of the translation bar 43 close to the mounting shaft 1 46 is rotatably mounted with mounting shaft 2 47 through bearings, and the push-pull bar 45 is rotatably mounted between the mounting shaft 1 46 and the mounting shaft 2 47.

[0034] When in use, the movable ends of the hydraulic cylinders are installed at the four corners of the top of the upper die base 2, and the upper die base 2 is driven by the hydraulic cylinder to move up and down, and the profile is placed between the four mounting bars 6. The hydraulic cylinder drives the upper die base 2 to move downward. When the profile is located between the clamping blocks 5 on both sides, the electric telescopic rod 41 is extended to drive the lifting bar 42 to move upward. Under the transmission action of the push-pull bar 45, the two translation bars 43 are pulled toward the center, that is, the profile is clamped between the clamping blocks 5 on both sides, so that the clamping blocks 5 are positioned and aligned to the center point;

[0035] Then the hydraulic cylinder continues to drive the upper die base 2 to move downward. At this time, the pressure on the mounting strip 6 will be transmitted to the T-block 35, and the spring 33 will be compressed, driving the profile to move downward, and finally the profile is located between the lower die base 1 and the upper die base 2 for stamping and forming. At this time, the profile falls off the mounting strip 6, ensuring that the profile descends synchronously with the descent of the upper die base 2 and contacts the mold core for forming.

[0036] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
