[0029] See also Figures 1 to 8 The utility model provides a space-saving and simple core-pulling structure, including a slider seat 1, a core-pulling 2 and a slider insert 3 connected to the core-pulling 2. The lower end of the slider seat 1 is slidably arranged on the stopper 4, the slider seat 1 is fixed on the front mold, the stopper 4 is fixed on the rear mold 5, a driving groove 101 is provided on the slider seat 1, and the core-pulling 2 is slidably arranged in the driving groove 101 through a connecting portion 201; when the mold is opened, the front mold drives the slider seat 1 to move upward, at this time the slider seat 1 slides along the stopper 4, and at the same time the slider seat 1 drives the core-pulling 2 and the slider insert 3 to move through the driving groove 101, so that the slider insert 3 is separated from the workpiece at the end to complete demolding.

[0030] In some embodiments, Figure 2 to Figure 7As shown, the driving groove 101 is an inclined T-shaped groove, and hollow parts 202 corresponding to the driving groove 101 are symmetrically arranged on both sides of the connecting part 201, so that the connecting part 201 can be movably assembled in the driving groove 101. When the slider 1 is lifted or lowered, the driving groove 101 and the connecting part 201 cooperate to drive the core pulling 2 to move along the inclined direction as a whole, thereby realizing the movement process of pulling downward obliquely, so as to drive the slider insert 3 at the end to move and then separate from the injection molded workpiece, wherein the slider 1 is provided with a cut surface 102 around the driving groove 101, The connecting portion 201 is located at the hollow portion 202 and fits with the cut surface 102. The cut surface 102 allows the connecting portion 201 to be directly inserted and assembled into the driving groove 101 from the bottom of the slider seat 1, thereby playing a role of avoidance. The block 4 is provided with a sliding groove 401 with an inclined end face. One side of the slider seat 1 is inclined and fits with the sliding groove 401. The sliding groove 401 guides and limits the movement trajectory of the slider seat 1. A rotating clamping portion 203 is provided at the end of the core pulling 2, and the slider insert 3 is rotatably connected to the rotating clamping portion 203.

[0031] In some embodiments, Figure 2 and Figure 8 As shown, the side end of the rear mold 5 is inclined to be provided with a mounting groove 501, and the core pulling 2 is movably installed in the mounting groove 501. The core pulling 2 can only move along the inclination of the mounting groove 501, and the sliding position insert 1 is coaxially arranged with the core pulling 2. The sliding position insert 1 passes through the rear mold 5 to connect with the external workpiece, so that the sliding position insert 1 can be controlled to move along a fixed trajectory and then detach from the workpiece; a limiting block 6 is fixed above the core pulling 2 in the rear mold 5, and a limiting notch 204 corresponding to the limiting block 6 is provided on the core pulling 2. After the core pulling 2 moves one end away from the limiting notch 204, the end of the limiting notch 204 abuts against the limiting block 6. At this time, the core pulling 2 cannot continue to move outward, which plays a limiting role. The rear mold 5 is symmetrically provided with grooves 502 on both sides of the core pulling 2, and the two ends of the stop block 4 are embedded and fixed in the grooves 502.

[0032] The utility model provides a space-saving simple core-pulling structure, which is partially embedded in the mold body and partially installed on the side wall of the mold, occupies less space and has low manufacturing cost. In addition, when the mold is opened, the slide seat can be driven to slide along the stop block, thereby synchronously driving the core-pulling movement on the slide seat to realize the core pulling and demolding of the slide insert. There is no need to install an additional driving structure, the overall structure is simple and the production efficiency is improved.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
