Figure 3 forFigure 1 The diagram shows a partial cross-sectional view of the limiting component. Figure 4 for Figure 2 The diagram shows a cross-sectional view of the adjustment component. A positioning device for an automotive foam mold includes: a first mounting component 1;

[0029] Limiting member 2, the limiting member 2 is disposed at the bottom of the first mounting component 1, and a buffer member 3 is provided on the inner side of the limiting member 2;

[0030] The second mounting component 4 is disposed on top of the first mounting component 1;

[0031] Adjustment component 5 is disposed at the bottom of the second mounting component 4. The adjustment component 5 includes a screw 51, a sliding member 52, a fixing ring 53, a rotating member 54, and a threaded ring 55. The sliding member 52 is disposed on the outer side of the screw 51. The fixing ring 53 is fixedly installed on the top of the sliding member 52. The rotating member 54 is rotatably connected to the outer side of the fixing ring 53. The threaded ring 55 is fixedly installed on the inner side of the rotating member 54 and threadedly connected to the outer side of the screw 51.

[0032] The limiting member 2 is cylindrical, and when in use, the outer side of the sliding member 52 can slide up and down against the inner side of the limiting member 2.

[0033] The buffer 3 can be made of spring, which can act as a buffer when compressed, and prevent impact between the upper and lower molds.

[0034] The first mounting assembly 1 includes a first annular fixing plate 11 and a first fixing bolt 12. The first fixing bolt 12 is respectively disposed inside the three circumferences of the first annular fixing plate 11, and one end of the first fixing bolt 12 acts to connect the lower mold.

[0035] When in use, the first fixing bolt 12 is passed through the first annular fixing plate 11, and one end of the first fixing bolt 12 is threadedly connected to the lower mold, thereby installing the first mounting component 1.

[0036] The second mounting component 4 includes a second annular fixing plate 41 and a second fixing bolt 42. The second fixing bolt 42 is respectively disposed inside the three circumferences of the second annular fixing plate 41, and one end of the second fixing bolt 42 acts to connect to the upper mold.

[0037] The second mounting component 4 is installed in the same way as the first mounting component 1. It is connected to the upper mold by the second fixing bolt 42 to fix the second annular fixing plate 41.

[0038] The top of the limiting member 2 and the bottom of the first annular fixing plate 11 are fixedly installed.

[0039] The top of the screw 51 is fixedly installed on the bottom of the second annular fixing plate 41.

[0040] Limiting grooves 56 are provided on both sides of the screw 51, and limiting blocks 57 are slidably connected to the inner sides of the two limiting grooves 56. The limiting blocks 57 are respectively fixedly installed on both sides of the inner side of the fixing ring 53. A base block 6 is fixedly installed at the bottom of the sliding member 52, and the base block 6 is set on the top of the buffer member 3.

[0041] The limiting block 57 slides on the inner side of the limiting groove 56, which can limit the sliding member 52 during use and prevent the sliding member 52 from rotating.

[0042] The working principle of the positioning device for automotive foam mold provided by this utility model is as follows:

[0043] After prolonged use, when the elasticity of the buffer 3 decreases, the operator can first separate the upper mold and lower mold used for foaming to the maximum extent. Then, the operator can rotate the rotating part 54, causing the rotating part 54 to drive the threaded ring 55 to make a threaded connection on the outer side of the screw 51, thereby driving the sliding part 52 to move upward, so that the bottom of the sliding part 52 moves out from the inner side of the limiting part 2. After that, the operator can remove and replace the buffer 3 located on the inner side of the limiting part 2.

[0044] Compared with related technologies, the positioning device for automotive foaming molds provided by this utility model has the following advantages:

[0045] By having the limiting component 2, the buffer component 3, and the adjusting component 5 work together, when the elasticity of the buffer component 3 decreases after the upper and lower molds for foaming have been working for a long time, the operator only needs to rotate the rotating component 54 to move the sliding component 52 out from the inner side of the limiting component 2. This makes it convenient for the operator to replace the buffer component 3 located on the inner side of the limiting component 2, which not only increases the replacement efficiency but also reduces the cost of use.

[0046] Second Embodiment

[0049] The working principle of the positioning device for automotive foam mold provided by this utility model is as follows:

[0050] When in use, the top of the buffer 3 is locked onto the inner side of the limiting ring 71, and then the locking screw 72 is rotated so that one end of the locking screw 72 abuts against the side of the buffer 3, thereby limiting the buffer 3. In this way, when the buffer 3 is disassembled later, the buffer 3 can be taken out from the inside of the limiting member 2 when the base block 6 moves upward.

[0051] Compared with related technologies, the positioning device for automotive foaming molds provided by this utility model has the following advantages:

[0052] The mounting plate 7, the limiting ring 71, and the locking screw 72 work together to allow the buffer 3 to be removed from the inner side of the limiting member 2 when it is replaced, thus making it convenient for the user to disassemble and replace the buffer 3.
