Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4 As shown, the utility model provides an injection mold for inlaying inserts, including an upper mold 1, a block template 2 is clamped on one side of the upper mold 1, a pair of first inclined blocks 3 are movably connected on the left and right sides of the inside of the block template 2, and the two first inclined blocks 3 are fixedly connected on the opposite sides, and the elastic sheet 4 is fixed on the block template 2. A cylindrical cam 5 and a second inclined block 8 are movably connected inside the upper mold 1, and a guide groove 6 is provided on the inner wall of the cylindrical cam 5 at an angle of 180 degrees. A limiting rod 9 is fixedly connected to one side of the second inclined block 8 close to the cylindrical cam 5, and a round rod 10 is fixedly connected to the other side of the second inclined block 8. A pair of third inclined blocks 11 and a fourth inclined block 13 are movably connected on the left and right sides of the inside of the upper mold 1, and the upper and lower ends of the third inclined block 11 are fixedly connected to a first spring 12 fixedly connected to the upper mold 1, and the opposite sides of the two fourth inclined blocks 13 are fixedly connected to a second spring 14 fixedly connected to the upper mold 1.

[0021] The above scheme is adopted: when the cylindrical cam 5 rotates, the protrusion slides along the trajectory of the guide groove 6, so that the limiting rod 9 drives the second inclined block 8 to move toward the insert template 2, and then the second inclined block 8 squeezes the two third inclined blocks 11 to move oppositely, so that the third inclined block 11 squeezes the fourth inclined block 13 to move toward the insert template 2, and then the fourth inclined block 13 abuts against the inclined surface of the first inclined block 3, and squeezes it to shrink into the inside of the insert template 2, and then the second inclined block 8 continues to move, thereby driving the round rod 10 to abut against the insert template 2, and squeezes the insert template 2 to move toward the outside of the upper mold 1, so as to facilitate the operator to take out the insert template 2 for replacement.

[0022] like Figures 1 to 4As shown, the side of the first inclined block 3 close to the upper mold 1 is in the shape of an inclined surface, the spring piece 4 is used to squeeze the first inclined block 3 and keep the two first inclined blocks 3 moving in opposite directions, the arc of the guide groove 6 is 360 degrees, and a protrusion is provided in a ring at 180 degrees on the end of the limit rod 9 away from the second inclined block 8, and the protrusion is movably engaged in the inside of the guide groove 6, and the end of the cylindrical cam 5 away from the second inclined block 8 is fixedly connected with a turning handle 7, which passes through the outer wall of the upper mold 1 and extends to the outside of the upper mold 1. When the cylindrical cam 5 rotates, the protrusion on the limit rod 9 moves along the trajectory of the guide groove 6 toward the direction of the insert template 2.

[0023] The above scheme is adopted: one side of the first inclined block 3 is in the shape of an inclined surface, and its function is that when the insert template 2 needs to be inserted into the upper mold 1, the insert template 2 is placed in the upper mold 1, so that the inclined surface of the first inclined block 3 abuts against the outer wall of the upper mold 1, and then the insert template 2 is moved toward the inside of the upper mold 1, so that the upper mold 1 squeezes the first inclined block 3 to shrink the inside of the insert template 2, thereby facilitating the insert template 2 to be inserted into the upper mold 1, and the two first inclined blocks 3 are squeezed by the spring sheet 4 to move in opposite directions. Its function is that when the first inclined block 3 is released from the abutment with the outer wall of the upper mold 1, the two first inclined blocks 3 move in opposite directions under the action of the elastic force of the spring sheet 4 to be reset, and the reset first inclined block 3 is inserted into the inside of the upper mold 1, thereby fixing the position of the insert template 2.

[0024] like Figures 2 to 4 As shown, the left and right ends of the upper and lower sides of the second inclined block 8 are both inclined, the third inclined block 11 is in the shape of a parallelogram, and the opposite ends of the two third inclined blocks 11 are respectively in contact with the inclined surfaces at both ends of the second inclined block 8, and the end of the fourth inclined block 13 close to the first spring 12 is inclined, and the opposite ends of the two third inclined blocks 11 are respectively in contact with the inclined surfaces of the two first springs 12. The first spring 12 is used to squeeze the third inclined block 11 and keep the two third inclined blocks 11 moving toward each other, and the second spring 14 is used to squeeze the fourth inclined block 13 and keep the fourth inclined block 13 moving toward the third inclined block 11.

[0025] The above scheme is adopted: the first spring 12 is used to squeeze the two third inclined blocks 11 to move toward each other, and the second spring 14 squeezes the fourth inclined block 13 to move toward the third inclined block 11. Its function is that when the insert template 2 is taken out, the operator rotates the handle 7 in the opposite direction, so that the cylindrical cam 5 rotates in the opposite direction, and then the protrusion drives the limit rod 9 to reset along the trajectory of the guide groove 6, and then the limit rod 9 drives the second inclined block 8 to release the abutment against the third inclined block 11, so that the third inclined block 11 is reset under the action of the elastic force of the first spring 12, and then the abutment against the fourth inclined block 13 is released, and then the fourth inclined block 13 is reset under the action of the elastic force of the second spring 14, so as to facilitate the operator's next use.

[0026] The working principle and use process of the utility model are as follows: when the insert template 2 needs to be replaced, the operator rotates the handle 7 to rotate the cylindrical cam 5, thereby causing the protrusion on the outer wall of the limit rod 9 to slide along the track of the guide groove 6. While the protrusion slides, the limit rod 9 drives the second inclined block 8 to move toward the insert template 2, and then the second inclined block 8 abuts against the third inclined block 11 and squeezes the two third inclined blocks 11 to move in the opposite direction. While the third inclined block 11 moves, it squeezes the fourth inclined block 13, so that the two fourth inclined blocks 13 are Move in the direction of the insert template 2, so that the fourth inclined block 13 abuts against the inclined surface of the first inclined block 3, and squeezes the two first inclined blocks 3 to move toward each other. When the plane of the second inclined block 8 abuts against the third inclined block 11, the fourth inclined block 13 squeezes the first inclined block 3 and completely shrinks it into the insert template 2. Then continue to rotate the handle 7, so that the limit rod 9 drives the second inclined block 8 to continue to move, so that the round rod 10 abuts against the side wall of the insert template 2, and squeezes the insert template 2 to move toward the outside of the upper mold 1, thereby facilitating the operator to take out the insert template 2.
