The moving component includes a roller 53, and the bottom end of the roller 53 rotates on the upper surface of the track. The cooperation between the roller 53 and the track can reduce friction and reduce wear on the roller 53. The top of the roller 53 is fixedly connected with a bottom plate 51 for supporting the lower mold 6. The top of the bottom plate 51 is fixedly connected with a positioning rod 52 for positioning the upper mold 3 to improve the stability of the lower mold 6 and the upper mold 3 when working. The outer wall at the top end of the positioning rod 52 is slidably connected with the lower mold 6.

[0033] Reference Figure 2 and Figure 4 The bottom end of the bottom plate 51 is fixedly connected with a limiting plate 1 54, which can be used in conjunction with a limiting block 1 56 to quickly position the bottom plate 51, thereby improving the efficiency of manufacturing the hood. The bottom plate 51 is provided with two groups, and the two groups of bottom plates 51 are symmetrically arranged on both sides of the base 1. The bottom end of the other group of bottom plates 51 is fixedly connected with a limiting plate 2 55, which can be used in conjunction with a limiting block 2 57, so that the other group of bottom plates 51 can be quickly limited. A limiting groove 1 is provided at the front end of the right side of the limiting plate 1 54, and the right side of the limiting groove 1 is set as an inclined surface. The two sides of the front end of the limiting plate 1 54 are set as inclined surfaces. Through the setting of the inclined surface, the limiting block 2 57 can be squeezed into the inner wall of the bottom plate 51 first, and then the limiting block 1 56 can be squeezed into the inner wall of the bottom plate 51, and then the limiting block 1 56 can slide into the inner wall of the limiting groove 1 through the elastic force of the compression spring 58, thereby limiting the limiting plate 1 54, thereby improving the efficiency of manufacturing the hood.

[0034] Reference Figure 3 and Figure 4 A limiting groove 2 is provided at the left front end of the limiting plate 2 55, and the left side of the limiting groove 2 is set as an inclined surface, and the two sides of the front end of the limiting plate 2 55 are set as inclined surfaces. Through the setting of the inclined surfaces, the limiting block 1 56 can be squeezed into the inner wall of the bottom plate 51, and then the limiting block 2 57 can be squeezed into the inner wall of the bottom plate 51, and then the elastic force of another group of compression springs 58 is used to make the limiting block 2 57 slide into the inner wall of the limiting groove 2, thereby limiting the limiting plate 2 55 and improving the efficiency of the manufacturing of the vehicle hood.

[0035] Reference Figure 4The inner wall of the middle part of the top of the base 1 is slidably connected to the limiting block 2 57, and the right side of the base 1 close to the limiting block 2 57 is slidably connected to the limiting block 1 56. The limiting block 2 57 is arranged on an inclined surface on the opposite side of the limiting block 1 56, which can be used in conjunction with the inclined surfaces on the limiting groove 1 and the limiting groove 2, so that the limiting block 2 57 and the limiting block 1 56 can slide into the inner wall of the bottom plate 51 to squeeze the two groups of compression springs 58. The limiting block 2 57 and the base 1 are elastically connected through the compression springs 58. The compression springs 58 are provided with two groups, and the other group of compression springs 58 is elastically connected to the inner wall of the base 1 and the front end of the limiting block 1 56. The elastic force of the two groups of compression springs 58 makes the limiting block 2 57 and the limiting block 1 56 slide into the limiting groove 1 and the limiting groove 2, thereby limiting the limiting plate 1 54 and the limiting plate 2 55.

[0036] Reference Figure 2 and Figure 3 A stabilizing component is provided on the right side of the bottom plate 51, and the stabilizing component includes a fixing plate 61, and the fixing plate 61 is used to fix the buffer column 62 and clean the track at the same time. The top of the fixing plate 61 is fixedly connected to the bottom end of the right side of the bottom plate 51, and a buffer column 62 is fixedly connected to the right side of the fixing plate 61. An annular groove is provided on the right outer wall of the buffer column 62. By using the annular groove in conjunction with the clamping plate 63, the buffer column 62 can be clamped, and the impact force of the buffer column 62 can be buffered and braked, thereby improving the stability of the bottom plate 51.

[0037] Reference Figure 5 and Figure 6 A clamping plate 63 is slidably connected to the inner wall on the right side of the base 1. The clamping plate 63 and the base 1 are elastically connected by a reset spring 64. The elastic force of the reset spring 64 drives the clamping plate 63 to squeeze the buffer column 62. There are two groups of clamping plates 63. The inner walls of the two groups of clamping plates 63 are provided with annular protrusions, and the annular protrusions are set to rubber material. The annular protrusions can fit with the annular grooves to increase the friction with the annular grooves, thereby improving the clamping stability and buffering effect. There are multiple groups of fixed plates 61 and buffer columns 62. The multiple groups of fixed plates 61 and buffer columns 62 are respectively arranged on the left and right sides of the two groups of bottom plates 51, which can buffer and clamp the two groups of bottom plates 51 and improve the stability of the two groups of bottom plates 51.

[0038] Working principle: When in use, when the output shaft of the hydraulic press 2 drives the upper mold 3 and the lower mold 6 to complete the manufacturing of the head cover, the upper mold 3 is first lifted upward to separate the upper mold 3 from the positioning rod 52. At this time, the worker can move a set of bottom plates 51 to the right through the rollers 53. When the bottom plates 51 move, the limiting plate 2 55 is driven to move. The limiting plate 2 55 contacts the inclined surface on the left side of the limiting block 2 57 through the inclined surface, so that the limiting block 2 57 slides out of the limiting groove 2 to release the limitation of the limiting plate 2 55, and drives the limiting block 2 57 to slide into the inner wall of the base 1. The compression spring 58 is squeezed, and at the same time, the limit block 1 56 makes the left side of the limit block 1 56 slide on its surface through the inclined surface to squeeze the other group of compression springs 58. When the limit plate 2 55 slides over the limit block 1 56, the bottom plate 51 drives the fixed plate 61 to clean the track, and at the same time drives the buffer column 62 to insert into the inner walls of the two groups of clamps 63, squeezes and buffers the buffer column 62, so as to protect the device. At this time, the head cover formed on the inner wall of the lower mold 6 can be taken manually, and the lower mold 6 can be cleaned for the next use.

[0039] When cleaning the lower mold 6, the worker moves another set of bottom plates 51 to the right at a uniform speed. At this time, the right inclined surface of the limiting plate 1 54 contacts the inclined surface of the limiting block 2 57, so that the limiting block 2 57 slides into the inner wall of the base 1 and squeezes the compression spring 58 at the same time. The limiting block 2 57 slides into the limiting groove 1 through the elastic force of the compression spring 58, and then slides out of the limiting groove 1 through the inclined surface of the limiting block 2 57. At this time, the inclined surface of the right side of the limiting plate 1 54 squeezes the limiting block 1 56, so that the limiting block 1 56 slides into the limiting groove 1 through the elastic force of another set of compression springs 58, and contacts the left inner wall of the limiting groove 1 through the left side of the limiting block 1 56, thereby limiting the limiting plate 1 54. At this time, start the hydraulic press 2 to slide the upper mold 3 into the positioning rod 52, so that the upper mold 3 and the lower mold 6 work, thereby manufacturing the hood. When the manufacturing is completed, the above operation can be repeated, which improves the efficiency of hood manufacturing.
