Problems solved by technology
[0002] For two sliders stacked together in the injection mold, it is necessary to control the sliding out of the two sliders in sequence when sliding. The slider that slides out for the first time is referred to as slider 1 here, and the slider that slides out for the second time is here. The slider 2 is referred to as the slider 2. The power source of the slider 2 is the slider 1. The existing technology is to use an elastic limit mechanism on the slider 2. The principle is that the limit part of the elastic limit mechanism is a slope, which is referred to as a limit slope. When the force of the slider acting on the limit slope exceeds a certain value, the limit part compresses the spring and retracts into the mechanism, and the slider 2 slides out; the disadvantage is that there is a constant gap between the slider 1 and the slider 2 during work. Mutual sliding will lead to wear and tear. After the wear, the friction force is too large, and it is easy to cause the slider 1 to slide to the designated position, the slider 2 is driven by the friction force, causing the product to be scratched and scrapped, and the pass rate is reduced. This is the case in actual production. Occurs frequently and repairs the mold frequently, so there are big problems and deficiencies in the existing technology

Embodiment Construction
[0020] refer to Figure 1-Figure 7 As shown, a sliding block of the present invention contains a sequential sliding control mechanism for the sliding block, including a locking block 1, a spring 2, a pressure block 3, a large sliding block 4, a sliding seat 5, and a wear-resistant block 6, wherein: the The four sides of the lock block 1 are in contact with the large slider 4. The upper left boss of the lock block 1 is called the hanging platform 12. The lock block 1 can slide up and down in the large slider 4, and is supported by the up and down movement of the hanging platform 12 and the pressure block 3. block.
[0021] The two ends of the spring 2 are in contact with the locking block 1 and the pressing block 3 respectively, and are in a compressed state.
[0022] The pressing block 3 is fixed on the large slide block 4 .
[0023] The bosses on both sides of the large slide block 4 are called guide rails 42, and the bead presses the guide rails 42 between the movable mold...

The invention discloses a sequent-sliding control mechanism for a sliding block with an internal sliding block. The sequent-sliding control mechanism comprises a lock block, a spring, a press block, a large sliding block, a sliding base and a wear resistant block, wherein four sides of the lock block and the large sliding block are in contact fitting; the lug boss at the left upper part of the lock block is named as a hanging stand; the lock block can slide up and down in the large sliding block, and is blocked by the hanging stand and the press block. The mechanism is stable to operate. Through the adoption of the mechanism, the quality and the qualified rate of products are greatly improved, and the cost for repairing molds is reduced.
Description
technical field [0001] The invention relates to an injection mold, in particular to a sequential sliding control mechanism in which a slider contains a slider. Background technique [0002] For two sliders stacked together in the injection mold, it is necessary to control the sliding out of the two sliders in sequence when sliding. The slider that slides out for the first time is referred to as slider 1 here, and the slider that slides out for the second time is here. The slider 2 is referred to as the slider 2. The power source of the slider 2 is the slider 1. The existing technology is to use an elastic limit mechanism on the slider 2. The principle is that the limit part of the elastic limit mechanism is a slope, which is referred to as a limit slope. When the force of the slider acting on the limit slope exceeds a certain value, the limit part compresses the spring and retracts into the mechanism, and the slider 2 slides out; the disadvantage is that there is a constant ...
