In order to ensure the safety of the automobile panel die in the transportation and placement state, rigid storage devices are often added at the end positions of an upper die seat and a lower die seat of the die, so that the elastic elements in the die are not compressed.
The existing automobile molds are generally divided into automatic line molds and non-automatic line molds, wherein the automatic line molds are stored by adopting nitrogen cylinders for supporting, and storage blocks are not needed; the non-automatic line mould generally uses ordinary tubular storage blocks, and is opened manually by field operators, and part of host factories develop special block storage blocks by themselves, so that the non-automatic line mould can be opened automatically without manual operation when the mould is opened, but the structure is complex and the cost is high.
In view of this, the present application proposes a mold storing block, and fig. 1 to 2 are an embodiment of the present application.
Referring to fig. 1 to 2, the mold storing block includes a storing block body 1 and a driving member 2, wherein the storing block body 1 is hinged on the lower mold, so that the storing block body 1 can be turned over in a direction, and has a first position for being placed between the upper mold and the lower mold and limiting the upper mold downward, and a second position for being deviated from the position between the upper mold and the lower mold to release the limitation of the upper mold downward on a turning stroke thereof; the driving piece 2 is used for being installed on the upper die, and the driving piece 2 is used for driving the storage block body 1 to move from the first position to the second position when moving along with the upper die and away from the lower die.
According to the technical scheme, when the die is stored, the storage block body 1 is arranged between the upper die and the lower die, so that the elastic element in the die is not compressed, when the die is opened, the driving piece 2 moves along with the upper die away from the lower die, and in the moving process, the storage block body 1 can be driven to turn over to one side of the lower die, at the moment, the storage block body 1 can not limit the die closing between the upper die and the lower die, the die can be closed to the bottom, the stamping production function is realized, namely, the function of automatically opening the storage block body 1 is realized through the movement of the upper die, and the risk of damage to the die structure during stamping caused by the leakage of the storage block body 1 is avoided.
Further, since there is a hinged connection between the storage block body 1 and the lower mold, the driving member 2 may drive the storage block body 1 to rotate by moving upwards, that is, specifically, in the present application, a protrusion 3 is formed on the storage block body 1, a first stop surface 4 disposed downward is disposed on the protrusion 3, and a second stop surface 5 disposed upward is formed on the driving member 2; when the driving member 2 moves upward, the first stop surface 4 and the second stop surface 5 abut against each other to drive the storage block body 1 to move. Through be provided with one on the driving piece 2 towards the second stop surface 5 that sets up the one side of depositing piece body 1 is provided with a boss 3, just be equipped with one on the boss 3 down the setting first stop surface 4, when driving piece 2 upward movement until second stop surface 5 upwards abuts first stop surface 4, because second stop surface 5 keeps moving upwards, and the one end of depositing piece body 1 articulates and installs on the bed die, then correspondingly, under the butt effect of second stop surface 5, first stop surface 4 with the butt position that second stop surface 5 contacted changes gradually, depositing piece body 1 is along with the upward movement of driving piece 2 is rotary motion to drive depositing piece body 1 rotates to one side of bed die, in order to realize depositing piece body 1's automatic opening.
It should be noted that, since the second stop surface 5 continues to move upward, the contact point with the first stop surface 4 is in the process of changing with each other, so that the first stop surface 4 and the second stop surface 5 are separated from each other, and when the first stop surface 4 and the second stop surface 5 are separated, the storage block body 1 continues to complete the rotation action under the action of gravity until rotating to one side of the lower mold, wherein, before the first stop surface 4 and the second stop surface 5 are not separated, the center of gravity of the storage block body 1 has crossed the axis along the up-down direction at the rotation midpoint of the storage block body 1 and the lower mold, that is, actively turned to one side of the lower mold under the action of gravity.
Specifically, the overturning direction of the storage block body 1 is taken as the left-right direction; the driving piece 2 comprises a driving arm 2a extending along the front-back direction, the driving arm 2a is used for being mounted on an upper die, and the upper side part of the driving arm 2a forms the second stop surface 5; the outside of depositing the piece is installed horizontal pole 6, horizontal pole 6 extends along controlling the orientation and sets up in order to form protruding portion 3, the downside of horizontal pole 6 forms first backstop face 4. Through being provided with crisscross setting drive arm 2a with horizontal pole 6, when the mould is opened, drive arm 2a rises along with last mould, when the upper side of drive arm 2a with the downside of horizontal pole 6 contacts, drive arm 2a passes through horizontal pole 6 gives deposit piece body 1 around its pin joint rotatory moment, deposit piece body 1 begins rotatory opening, works as after the center of depositing piece body 1 bypasses the axis of upper and lower decurrent, deposit piece body 1 continues to rotate under the effect of dead weight until reaching spacing position, in order to reach the automatic effect of opening deposit piece body 1.
Referring to fig. 2, the driving member 2 further includes a mounting bracket 2b, and the driving arm 2a is rotatably mounted on the mounting bracket 2b along a left-right axis; a limiting block 7 is mounted on the mounting bracket 2b, and the limiting block 7 is used for limiting the driving arm 2a to rotate downwards when the first stop surface 4 and the second stop surface 5 are abutted against each other. By arranging the mounting bracket 2b and the limiting block 7, in a normal state of the driving arm 2a, the driving arm 2a keeps a static state extending forwards and backwards under the action of gravity and the limiting action of the limiting block 7, so that in the process that the driving arm 2a moves upwards along with an upper die, the driving arm 2a and the cross rod 6 can be ensured to be mutually abutted to drive the storage block body 1 to rotate; when the storage block body 1 is located at the first position, the mounting bracket 2b is disposed at the lower end of the upper mold, and when the upper mold does not contact the upper end of the storage block body 1, the lower side portion of the driving arm 2a preferentially contacts the upper side portion of the cross bar 6, so that under the abutting action of the upper side portion of the cross bar 6, the driving arm 2a rotates, and further, hard abutting between the driving arm 2a and the cross bar 6 does not occur, so that the upper mold can be ensured to normally fall at the upper end of the storage block body 1 when moving downwards.
It will be appreciated that the centre of gravity of the drive arm 2a does not always exceed the vertical axis at its centre of rotation as it rotates, so that after separation of the drive arm 2a from the cross bar 6, the drive arm 2a can continue to return to a rest condition extending in a forward and rearward direction under the force of gravity.
Further, the driving arm 2a includes a driving section 201 and a limiting section 202 that are connected to each other in a front-rear direction, the limiting section 202 is disposed at a rear side of a rotation center of the driving arm 2a, the limiting block 7 is correspondingly disposed at an upper side of the limiting section 202, so as to abut against an upper side of the limiting section 202 when the first stop surface 4 and the second stop surface 5 abut against each other, the driving section 201 is disposed at a front side of the rotation center of the driving arm 2a, and an upper end of the driving section 201 forms the second stop surface 5; the length of the driving section 201 is greater than the limit section 202. By taking the rotation center of the driving arm 2a as a parting line, the driving section 201 is arranged in front of the rotation center of the driving arm, and the limiting section 202 is arranged behind the rotation center of the driving arm, namely, in order to ensure that the driving arm 2a can keep a static state extending along the front-back direction when not in use, the limiting block 7 is arranged at the upper end of the limiting section 202, the lower end of the limiting block 7 is abutted against the upper end of the limiting section 202, the driving section 201 can move rotationally only when the lower side of the driving arm 2a is abutted against the upper side of the cross rod 6, and the length of the driving section 201 is arranged to be larger than the length of the limiting section 202, namely, the moment of the driving section 201 is longer than the moment of the limiting section 202, so that the driving arm 2a can be prevented from rotating under the condition of external interference, and the stability of the driving arm 2a can be improved.
Still further, the limiting block 7 is provided with a third stop surface 8 extending from back to front and inclined upward, and the third stop surface 8 is used for abutting against the second stop surface 5 when the driving arm 2a rotates to a preset angle so as to limit the rotation range of the driving arm 2 a. In this embodiment, when the lower side of the driving arm 2a abuts against the upper side of the cross bar 6, the driving arm 2a rotates around the axis in the left-right direction, which does not avoid that the rotation angle of the driving arm 2a exceeds the axis in the up-down direction during rotation, so that the driving arm 2a cannot return to the original rest position extending in the front-back direction under the action of gravity, therefore, the third stop surface 8 is provided on the limiting block 7, and the angle between the third stop surface 8 and the axis in the front-back direction is smaller than 90 ° so as to ensure that the driving arm 2a cannot cross the axis in the up-down direction during rotation, so that the driving arm 2a can always return to the rest position under the action of gravity.
Referring to fig. 2, the lower end surface of the driving section 201 extends from back to front and is disposed obliquely upward. By providing the lower end surface of the driving section 201 with a slope, the separation of the driving section 201 from the cross bar 6 can be accelerated when the driving arm 2a approaches the lower die along with the upper die.
Referring to fig. 1, the cross bar 6 tapers from right to left. Through setting up horizontal pole 6 convergent setting, when actuating arm 2a upwards butt horizontal pole 6's lower extreme drives deposit piece body 1 rotatory, actuating arm 2a can be faster with separate between the horizontal pole 6, when actuating arm 2a downwards butt horizontal pole 6's upper side, actuating arm 2a can be faster break away from horizontal pole 6.
The relative angle between the driving arm 2a and the cross bar 6 is not limited, but is not limited to the 90 ° angle formed by the cross bar 6 and the driving arm 2a, and the upper side portion of the driving arm 2a may abut against the lower side portion of the cross bar 6 when the driving arm moves upward, and the mold closing between the upper mold and the lower mold may not be affected.
