Because of 3 locators need to look at in advance when putting on the press work platen, take the meter chi to measure again, later put 3 locators to corresponding position again, not only waste time and energy, the locator is easy to lose, simultaneously, the depositing of locator also is very occupation space.

Disclosure of Invention

An object of the utility model is to provide a upgrade quick mounting structure of mould to it wastes time and energy to overcome the current mould installation that upgrades, and the locator is easily lost, and depositing of locator also very occupation space's shortcoming.

The utility model aims at realizing through the following technical scheme:

the utility model provides a quick mounting structure of mould upgrades which characterized in that: consists of a fixed plate, a rectangular spring and a positioner;

a round hole is formed in the fixing plate, the rectangular spring is compressed in the round hole of the fixing plate, and the gap between the outer diameter of the rectangular spring and the single face of the round hole of the fixing plate is 0.5 mm;

the upper part of the positioner is in contact with the rectangular spring, the positioner consists of a stepped part at the top, a non-stepped part at the middle part and the bottom, the stepped part is arranged in a round hole of the fixed plate, and the clearance between the outer diameter of the stepped part and the inner diameter single face of the round hole of the fixed plate is 0.5 mm;

the middle part and the non-step part at the bottom of the positioner are arranged in a rectangular groove of a lower die seat of the progressive die and can move up and down in the groove, and the protruding part at the bottom is used for connecting a U-shaped groove of a working platen of the press.

Further, the fixed plate is fixed with the base of the progressive die through 2 socket head cap screws.

Further, the compression amount of the rectangular spring is ten percent.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the utility model has simple structure and smart design, when the progressive die is installed by adopting the rapid installation structure of the progressive die, the positioner does not need to find and measure, and the positioner directly aims at the U-shaped groove of the lower table surface of the press machine, thus being rapid, simple and safe; because the mounting structure is elastic, the die does not influence storage when not working, and the situation that the positioner is lost does not occur.

In the drawing, the press machine comprises a fixing plate 1, a fixing plate 2, a rectangular spring 3, a positioner 31, a step portion 32, a protruding portion 4, a press workbench 5, a positioning key 6, a progressive die 7, a mounting structure 8, an inner hexagon screw 9, a U-shaped groove 10 of a press workbench plate, a ground 11 and a storage batten.

Detailed Description

The invention is further illustrated by the following examples:

as shown in fig. 3 and 4, the utility model discloses the quick mounting structure of progressive die comprises fixed plate 1, rectangle spring 2 and locator 3 (the circle shows to be the quick mounting structure position of progressive die in fig. 4).

The fixing plate 1 is provided with a round hole, the rectangular spring 2 is compressed in the round hole of the fixing plate 1, the compression amount is ten percent, and the positioner can be ensured to protrude out of the lower surface of the die as required. The clearance between the outer diameter of the rectangular spring 2 and the single surface of the round 1 hole of the fixing plate is 0.5 mm.

The upper part of the positioner 3 is in contact with the rectangular spring 2, a contact surface is arranged between the positioner and the rectangular spring, and no special connection mechanism is arranged. The retainer 3 is composed of a stepped portion 31 at the top and non-stepped portions at the middle and bottom, wherein the stepped portion 31 is disposed in a circular hole of the fixing plate 3, so that the upper and lower degrees of freedom of the rectangular spring and the retainer are controlled. The clearance between the outer diameter of the step part 31 and the inner diameter single side of the round hole of the fixing plate 1 is 0.5mm, so that the freedom degree is controlled at all sides. The middle part and the non-step part at the bottom of the positioner 3 are arranged in a rectangular groove of a lower die holder of the progressive die and can move up and down in the groove, and the bottom protruding part 32 is used for connecting a U-shaped groove 9 of a working table plate of the press (the structure of the U-shaped groove of the working table plate is the same as that in the prior art).

The left, right, front and rear positions of the positioner 3 are controlled by four surfaces of a rectangular groove of the lower die holder of the progressive die, and the positioner can not be separated from the die downwards through the step part 31 of the positioner. The fixing plate 1 mainly functions as a mounting socket of the rectangular spring 2, so that the freedom degree of the rectangular spring 2 can be limited as required.

The utility model discloses upgrade quick mounting structure of mould, when the installation mould, with the crane hoist the mould, the protruding part 32 of locator 3 aims at the U-shaped recess 9 of press work platen and puts down can. The situation on the press is shown in figure 3. This scheme simple structure, the mould position through quick location structure installation is accurate. And is not affected when stored, and the storage state is shown in figure 5.
