In order to make the technical scheme and beneficial effects of the technical problem solved by the invention more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to 4, a mold with a connecting rod demolding structure includes a row position 1, an insert 2 arranged on the row position 1, a connecting rod mechanism 3 for driving the insert 2 to move towards an insert demolding direction or an insert mold closing direction, and a side row position 5, wherein the insert demolding direction of the insert 2 is intersected with the row position demolding direction of the row position 1, and the side row position demolding direction of the side row position 5 is intersected with the row position demolding direction of the row position 1. In this embodiment, the demolding direction of the insert is identical to the mold opening direction, so that the height dimension of the mold increases if the conventional row-level design is adopted.
According to the die with the connecting rod demolding structure, the insert is arranged on the row position, so that the insert is withdrawn from the buckling position of a product in advance before demolding, and then the product is withdrawn from the row position, and the product can be demolded smoothly. The movement of the insert is realized through the connecting rod mechanism, and the insert and the connecting rod mechanism are arranged in the row position, so that the conventional mould structure of which the row position exits the buckling position is replaced, and the size and the manufacturing difficulty of the mould can be reduced.

Further, as a preferred embodiment of the present invention, but not limited to, the linkage mechanism 3 further includes a return spring 36 disposed between the slide seat 31 and the slide 1, and the return spring 36 pushes the slide seat 31, so that the slide seat 31 has a movement tendency to drive the insert 2 to move in the insert demolding direction. After the die is opened, the insert moves towards the demolding direction of the insert under the action of the return spring, so that the effect that the insert automatically releases from the buckling position is achieved, and a power source such as an oil cylinder is not required to be additionally arranged.
Further, as a preferred embodiment of the present invention, but not limited to, the row 1 is provided with a rotation groove 11, and the rotation groove 11 is used for limiting the rotation angle of the connecting rod 32, so that the movement of the insert 2 is stopped after the connecting rod 32 drives the insert to move toward the insert demolding direction to the insert demolding position. When the rotating groove is propped against one of two sides of the connecting rod, the connecting rod reaches the maximum rotating position for controlling the position of the insert.
Further, as a preferred embodiment of the present invention, but not limited to, the slide seat 31 is provided with a movable slot 12 for sliding the slide seat 31, and a mounting block 13 for restricting the slide seat 31 to the movable slot 12, wherein the mounting block 13 is used for restricting the slide seat 31 to move along the length direction of the movable slot 12. Under the action of the mounting block, the slide seat can only move linearly.
Further, as a preferred embodiment of the present invention, but not limited thereto, a limiting mechanism 4 for limiting the moving distance of the row seat 31 is provided between the row seat 1 and the row seat 31.
Further, as a preferred embodiment of the present solution, but not limited thereto, the limiting mechanism 4 includes a bottom plate 41 disposed on the row seat 1, a limiting block 42 detachably connected to the bottom plate 41, and a limiting groove 43 is disposed on the row seat 31, and the limiting block 42 is embedded in the limiting groove 43 to limit the moving distance of the limiting groove 43. The limiting groove moves relative to the limiting block, and the limiting block is kept in the limiting groove.
Further, as a preferred embodiment of the present invention, but not limited to, the slide seat 31 is further provided with a positioning groove 44 configured to be spaced from the limiting groove 43, and when the limiting block 42 is matched with the positioning groove 44, the slide seat 31 drives the insert 2 to maintain the demolding state. When the mold is disassembled, the positioning groove is matched with the limiting block, so that the position of the insert can be fixed.
Further, as a preferred embodiment of the present invention, but not limited thereto, the mold insert mold further comprises a virtual position resetting mechanism 6, wherein the virtual position resetting mechanism 6 is used for driving the mold insert 2 to continue to move to the mold insert mold clamping position after the mold insert 2 moves in the mold insert mold clamping direction, and the mold insert demolding direction of the mold insert 2 intersects with the row position demolding direction of the row position 1.
Further, as a preferred embodiment of the present invention, but not limited to, when the slide seat 31 moves linearly relative to the slide 1, the link 32 rotates relative to the slide 1 with the third pin 35 as a rotation axis, the first sliding groove 321 yields the first pin 33, the second sliding groove 322 yields the second pin 34, the dummy position resetting mechanism 6 includes a pressing block 61 provided on an upper die, and when the die with the dummy position resetting structure is closed, the pressing block 61 is pressed against the insert 2 to offset the yield of the second sliding groove 322, so that the insert 2 continues to move to the insert closing position. After the second bolt lifts the insert from the insert die-closing position to the insert die-closing position, because the second chute has the function of giving way to the second bolt and the insert lacks a power source, the second bolt moves along with the connecting rod to drive the insert to move from the insert die-closing position to the insert die-closing position, so that the insert can not finish moving to the insert die-closing position, and the generated virtual position needs to be counteracted by the virtual position reset mechanism. When the die is closed, the pressing block is pressed against the insert, so that the insert continues to move to the die closing position of the insert.
Further, as a preferred embodiment of the present invention, but not limited to, the pressing block 61 is provided with an inclined guide post 62, the slide seat 31 is provided with an inclined hole 311 matching with the inclined guide post 62, and when the mold with the virtual position resetting structure is closed, the inclined guide post 62 pushes the slide seat 31 to drive the insert 2 to move toward the mold closing direction.
Further, as a preferred embodiment of the present invention, but not limited to, when the slide seat 31 moves linearly relative to the slide 1, the connecting rod 32 drives the insert 2 to move linearly, and the direct movement direction of the insert 2 is perpendicular to the slide demolding direction of the slide 1.
