Description

Sequential sliding control mechanism with sliding block in sliding block

Technical Field

The invention relates to an injection mold, in particular to a sequential sliding control mechanism with a sliding block in the sliding block.

Background

In the injection mold, two sliding blocks are laminated together, the two sliding blocks need to be controlled to slide out sequentially during sliding, the sliding block which slides out for the first time is called a sliding block 1 for short, the sliding block which slides out for the second time is called a sliding block 2 for short, the power source of the sliding block 2 is the sliding block 1, the prior art adopts an elastic limiting mechanism on the sliding block 2, the principle is that the limiting part of the elastic limiting mechanism is an inclined plane which is called a limiting inclined plane for short, when the force of the sliding block acting on the limiting inclined plane exceeds a certain value, the limiting part compresses a spring and retracts into the mechanism, and the sliding block 2 slides out; firstly, the sliding block 1 and the sliding block 2 continuously slide with each other in work, so that abrasion is caused, the friction force is overlarge after abrasion, when the sliding block 1 is not slid to a specified position easily, the sliding block 2 is driven by the friction force, so that products are damaged and scrapped, the qualification rate is reduced, the situation is frequently generated in actual production, and the die is frequently repaired, so that the prior art has larger problems and defects.

Disclosure of Invention

Aiming at the problems and the defects in the prior art, the sequential sliding control mechanism with the sliding block in the sliding block provided by the invention utilizes the locking block to control the sequential sliding of the double-layer sliding block, so that the stability of the mechanism is ensured, the quality and the qualification rate of products are greatly improved, and the die repairing cost is reduced.

The purpose of the invention is realized as follows: the invention relates to a sequential sliding control mechanism with a sliding block in the sliding block, which comprises a locking block, a spring, a pressing block, a large sliding block, a sliding seat and a wear-resisting block, wherein: the four sides of the locking block are in contact fit with the large sliding block, a boss at the left upper part of the locking block is called a hanging table, and the locking block can slide up and down in the large sliding block and is blocked by the hanging table and the pressing block up and down.

The two ends of the spring are respectively contacted with the locking block and the pressing block and are in a compressed state.

The pressing block is fixed on the large sliding block.

The bosses on the two sides of the large sliding block are called as guide rails, the guide rails are pressed between the movable die frame and the wear-resistant block by the pressing strips, and the large sliding block slides between the movable die frame and the wear-resistant block.

The big sliding block is provided with a T-shaped groove, and the small sliding block can slide on the T-shaped groove.

The sliding seat is provided with a boss which is matched with the small sliding block, a bevel angle is arranged at a square hole in the middle of the sliding seat as shown in a figure (2), the right side surface of the square hole is called a pushing surface and is contacted with the locking block, the right side of the sliding seat is connected with the oil cylinder, the upper surface of the sliding seat is contacted with the large sliding block, and the lower surface of the sliding seat is contacted with the wear-resistant block. The wear-resistant block is fixed on the movable die frame, a square hole is formed in the middle of the wear-resistant block, and the right side face of the square hole is called a stop face.

The working principle is as follows: after the small sliding block moves obliquely until the small sliding block is separated from a product, then an oblique angle on the sliding seat touches an oblique plane on the locking block, the locking block is pushed by the oblique angle, the oblique plane converts force into upward thrust, and the locking block is pushed upward, as shown in a figure (5); when the locking block moves upwards until the locking block is separated from the stop surface on the wear-resistant block, the sliding block and the large sliding block do not move relatively, the sliding seat drives the locking block and the large sliding block to move rightwards together as shown in a figure (6), until the large sliding block is separated from a product as shown in a figure (7), and the mold stripping process of the whole group of sliding blocks is completed.

Has the advantages that: the mechanism has a safe and reliable structure, solves the problem that the sliding block which slides for the second time is too early to slide out due to overlarge friction force between the two sliding blocks in the prior art, improves the quality and the qualification rate of products, greatly reduces the die repairing cost and improves the production benefit.
