[0022] There are inclined surfaces on both sides of the sliding plate 1. The top of the abutment block 3 is composed of a displacement surface and a plane. Two threaded holes are opened on the top of the slider 5. The two threaded holes are adapted to the fixing bolts 6. The fixing bolts 6 pass through the slider 5 and are threadedly connected to the sliding plate 1.

[0024] During the mold closing process, the oil cylinder 15 drives the core pulling body to move, and the connecting block 12 drives the sliding plate 1 to move to the left. At the same time, the slider 5 and the slide plate 7 on the top of the sliding plate 1 slide in the first slide groove 9 and the second slide groove 10 of the pushing block 8. The left inclined surface of the sliding plate 1 and the inclined surface at the bottom of the pushing block 8 produce relative displacement. After moving a certain distance, the plane on the top of the abutment block 3 and the plane at the bottom of the pushing block 8 contact and generate friction, thereby fixing the core pulling body.

[0025] A snap-in groove 11 is provided on the right side of the sliding plate 1, a connecting block 12 is snap-into the inside of the snap-in groove 11, a connecting hole 13 is provided on the right side of the connecting block 12, a core pulling body 14 is fixedly connected to the inside of the connecting hole 13, and an oil cylinder 15 is provided on the right side of the core pulling body 14.

[0026] The bottom end of the sliding plate 1 is slidably connected to a sliding seat 16 , a limiting groove 17 is provided on the top of the sliding seat 16 , a positioning block 18 is clamped on the top of the limiting groove 17 , and an inner wall of the positioning block 18 is provided with an interference groove 19 .

[0027] There are two limit grooves 17 , and two limit blocks are provided at the bottom end of the positioning block 18 . The limit blocks are adapted to the limit grooves 17 . A contact surface is provided on the left side of the contact groove 19 , and the contact surface contacts the right inclined surface of the sliding plate 1 .

[0028] The top of the positioning block 18 is fixedly connected to a telescopic rod 20 , a return spring 21 is movably sleeved on the surface of the telescopic rod 20 , and the top of the telescopic rod 20 is fixedly connected to a mounting plate 22 , a mounting hole 23 is opened on the top of the mounting plate 22 .

[0030] The utility model provides a core pulling structure of an oil cylinder for SMC molding, and the specific working principle is as follows:

[0031] When the cam 18 is in the process of closing the mold, the oil cylinder 15 drives the core pulling body to move, so that the connecting block 12 drives the sliding plate 1 to move to the left, and pushes the positioning block 18 upward, so that the return spring 21 and the telescopic rod 20 are squeezed and contracted. At the same time, the slider 5 and the slide plate 7 on the top of the sliding plate 1 slide in the first slide groove 9 and the second slide groove 10 of the pushing block 8. The left inclined surface of the sliding plate 1 and the inclined surface at the bottom of the pushing block 8 produce relative displacement. After moving a certain distance, the plane at the top of the abutment block 3 contacts the plane at the bottom of the pushing block 8 and generates friction, thereby playing the role of fixing the core pulling body. At the same time, the positioning block 18 is engaged with the limiting block at its bottom in the limiting groove 17 of the sliding seat 16 under the action of the elastic force of the return spring 21. At the same time, the contact surface of the abutment groove 19 contacts the right inclined surface of the sliding plate 1, thereby fixing the position of the sliding plate 1, strengthening the stability of the core pulling body and preventing it from falling back.
