DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0018] like Figures 1 to 5 As shown, a preferred embodiment of an insert insert front mold anti-collision mechanism is shown, comprising:

[0019] A front mold 1, a rear mold 2, a first slider 3, a second slider 4 and two inclined guide pillars 5, the front mold 1 is arranged above the rear mold 2, the front mold 1 is moved in the vertical direction by a driving member, the front mold 1 can be operably moved close to or away from the rear mold 2, the first slider 3 and the second slider 4 are slidably installed on the lower surface of the front mold 1, the first slider 3 is provided with a first through hole 15, the second slider 4 is provided with a second through hole 16, the lower ends of the two inclined guide pillars 5 are both installed on the upper surface of the front mold 1, the upper ends of the two inclined guide pillars 5 are inclined in a direction away from each other, the upper ends of the two inclined guide pillars 5 extend into the first through hole 15 and the second through hole 16, the two inclined guide pillars 5 are used to drive the first slider 3 and the second slider 4 to move closer to or away from each other, one end of the first slider 3 is provided with a plurality of first positioning grooves 6, one end of the second slider 4 is provided with a plurality of second positioning grooves 7, the plurality of first positioning grooves 6 and the plurality of second positioning grooves 7 can operably form a plurality of positioning holes 8.

[0020] In actual use, when the front mold 1 is opened relative to the rear mold 2 and moves upward, the front mold 1 drives the first slider 3 and the second slider 4 to move upward at the same time. Since the first slider 3 and the second slider 4 are sleeved on the two inclined guide pillars 5 through the first through hole 15 and the second through hole 16, when the first slider 3 and the second slider 4 move upward, the first slider 3 and the second slider 4 move away from each other in the horizontal direction, so that one end of the first slider 3 and the one end of the second slider 4 move away from each other, thereby opening a plurality of positioning holes 8 and completing demoulding. When the front mold 1 is closed relative to the rear mold 2 and moves downward, the front mold 1 drives the first slider 3 and the second slider 4 to move upward. The first slider 3 and the second slider 4 move downward at the same time. Since the first slider 3 and the second slider 4 are sleeved on the two inclined guide pillars 5 through the first through hole 15 and the second through hole 16, when the first slider 3 and the second slider 4 move downward, the first slider 3 and the second slider 4 approach each other in the horizontal direction, so that one end of the first slider 3 and one end of the second slider 4 approach each other, so that the first positioning grooves 6 and the positioning grooves are closed and the positioning holes 8 are formed, so as to complete the positioning of the copper sheets. When the first positioning grooves 6 and the positioning grooves are close to each other, the extrusion of the copper sheets is avoided, thereby ensuring the product yield.

[0021] Further, as a preferred embodiment, the cross-sections of the plurality of first positioning grooves 6 along the horizontal direction are all arranged in an "L" shape, and the cross-sections of the plurality of second positioning grooves 7 along the horizontal direction are all arranged in a "┐" shape. Further, the plurality of first positioning grooves 6 are arranged in sequence along the width direction of one end of the first slider 3, and the plurality of second positioning grooves 7 are arranged in sequence along the width direction of one end of the second slider 4, and the plurality of first positioning grooves 6 and the second positioning grooves 7 together form a plurality of positioning holes 8 arranged in a rectangular shape.

[0022] Further, as a preferred embodiment, the axis of the first through hole 15 and the axis of the second through hole 16 are both inclined. Further, the axis of the first through hole 15 and the axis of the second through hole 16 are inclined to facilitate movement along the length direction of the two inclined guide pillars 5, so that the first slider 3 and the second slider 4 are close to or away from each other.

[0023] Furthermore, as a preferred embodiment, the first through hole 15 includes a first channel portion and a second channel portion connected up and down, the inner wall of the first channel portion on the side away from the second slider 4 has a first inclined surface 9, and the inner wall of the second channel portion on the side close to the second slider 4 has a second inclined surface 10, and the upper end of the first inclined surface 9 and the upper end of the second inclined surface 10 are both away from the second slider 4.

[0024] Furthermore, as a preferred embodiment, the second through hole 16 includes a third channel portion and a fourth channel portion which are connected up and down, the inner wall of the third channel portion on the side away from the first slider 3 has a third inclined surface 11, and the inner wall of the fourth channel portion on the side close to the first slider 3 has a fourth inclined surface 12, and the upper ends of the third inclined surface 11 and the fourth inclined surface 12 are both away from the first slider 3.

[0025] Furthermore, as a preferred embodiment, an upper locking surface is provided on the upper portion of the outer wall of each inclined guide column, and a lower locking surface is provided on the lower portion of the outer wall of each inclined guide column. The first inclined surface 9 and the third inclined surface 11 can be operably fitted with the upper locking surface, and the second inclined surface 10 and the fourth inclined surface 12 can be operably fitted with the lower locking surface. Furthermore, in actual use, when the front mold 1 is in close contact with the rear mold 2, the second inclined surface 10 of the second channel portion and the fourth inclined surface 12 of the fourth channel portion are in close contact with the lower inclined surfaces 14 of the two inclined guide pillars 5, thereby preventing the first slider 3 and the second slider 4 from shaking. When the front mold 1 is opened relative to the rear mold 2 and moves upward to the first inclined surface 9 of the first channel portion and the third inclined surface 11 of the third channel portion are in close contact with the upper inclined surfaces 13 of the two inclined guide pillars 5, one end of the first slider 3 and one end of the second slider 4 remain in contact. When the lower surfaces of the first slider 3 and the second slider 4 both move to above the upper inclined surfaces 13 of the two inclined guide pillars 5, several positioning holes 8 are fully opened, and the first inclined surface 9 and the second inclined surface 10 and the third inclined surface 11 and the fourth inclined surface 12 are all abutted against the outer walls of the two inclined guide pillars 5, preventing the first slider 3 and the second slider 4 from shaking.
