The present invention relates to a die spotting press used for the upper and lower mold matching and mold modification of the upper and lower molds, and in particular, can be set by adjusting the difficulty of lowering the upper mold more accurately during large mold matching and modification. Accordingly, the present invention relates to an inverted die spotting press equipped with an upper mold microadjustment device, which improves the convenience of work during the mold precision work, the adjustment of the falling displacement, and the stability.

Normally, during the mold machining operation, one mold is processed precisely from the beginning, and the other mold that is engaged by being combined with one mold is roughly processed first, and then the other mold is precisely matched to one of the precisely processed molds. After checking and reworking, it is refitted. That is, in the case of mold processing, the above-described process is repeated several times, and the upper and lower molds having accurate dimensions with one mold are made while increasing the precision of the other mold that is roughly processed. In this case, the die spotting press is the equipment that moves the other mold roughly processed and makes contact with the precisely processed mold when the mold is processed. A tool that can help you correct the inconsistent part of the face after separating and inverting it. The mold is inverter.

This die spotting press is provided with an upper mold 101 on a slider 106 which is moved up, down, and lowered between both support frames 104 of the bed 103 shown in FIG. The lower mold 102 to which the mold 101 is fitted is seated.

Therefore, the upper mold 101, which is processed up and down by the slider 106, is fitted to the precisely processed lower mold 102 to check the machining surface that is inappropriately matched, and then the upper mold 101 is checked. After raising and reversing, the machining surface is precisely machined, and then the work is performed to fit the lower mold 102 again.

However, the conventional die spotting press has a problem that the precision cannot be reduced because the slider cannot be inverted when the upper mold is adjusted in the vertical state, and thus the work is difficult when the upper mold is modified, and furthermore, when pressing an article such as a vehicle bonnet. When the large mold used is inverted when using a reversal equipment, but the falling displacement control means for adjusting the mold precisely and finely provided there was a disadvantage that a lot of working time and precision in the work of the mold is inferior.

Therefore, the present invention has been invented to solve the conventional problems as described above, and when the upper mold is matched to the lower mold when the large mold processing, the adjustment is performed more precisely and stably to shorten the modification time of the mold and ensure the stability and It is an object of the present invention to provide an inverted die spotting press equipped with a mechanical upper mold lowering fine adjustment device in which precision work is improved.
