AI Technical Summary
The existing slider mold opening structure is inefficient and easily causes drag marks on the sides of injection molded products, affecting the appearance and yield.
The mold opening device uses a large and small slider. The slider is driven into the drive part of the ejector slide, and the inclined surface is used to make the ejector slide within the moving slider to push out the injection molded part, thus realizing automated mold opening and avoiding damage to the injection molded part.
It improves mold opening speed and production efficiency, reduces deformation and damage of injection molded parts, and ensures a high yield rate of finished products.

Abstract
Claims
1. A size slide opening device characterized by: The device includes a fixed slide on a plane, a movable slide slidably disposed on the fixed slide and integrally matched with the fixed slide, at least one injection cavity formed between the fixed slide and the movable slide and accommodating an injection molded part, at least one drive slider fixedly disposed inside the fixed slide on the side of the injection cavity and protruding in the moving direction, and at least one ejector slide slidably disposed inside the movable slide on the side of the injection cavity. The ejector slide has a drive part formed inside for the drive slider to be inserted into, and an ejector part formed on the ejector slide that penetrates into the injection cavity and presses the side wall of the injection molded part to open the mold.
2. The size slide opening device of claim 1, wherein: The drive slider has a first drive slope extending outward from the direction of the sliding block moving inside the injection cavity at one end. The inner wall of the drive part has a second drive slope extending outward from the direction of the drive slider away from the injection cavity and matching the first drive slope.
3. The size slide opening device of claim 2, wherein: The upper and lower ends of the drive slider are respectively formed with an outwardly protruding drive limiting block, and the upper and lower ends of the drive part are respectively formed with a drive limiting groove for the drive limiting block to be placed.
4. The size slide opening device of claim 3, wherein: The outer end of the drive limiting block away from the first drive inclined surface has a vertical guide surface that is parallel to the outer wall of the drive slider.
5. The size slide opening device of claim 1, wherein: The movable slide has a slide moving groove for the ejector slide to slide in the left and right directions, and the movable slide also has an ejection groove for the ejector part to slide in the left and right directions and protrude into the injection cavity.
6. The size slide opening device of claim 5, wherein: An ejection limiting block is formed on the inner wall of the injection cavity at the foremost end of the ejection groove.
7. The size slide opening device of claim 5, wherein: It also includes a movable limiting seat respectively disposed at the upper and lower ends of the sliding groove of the slide, and a movable limiting block protruding outward is formed at the upper and lower ends of the ejector slide, and the movable limiting seat abuts against the movable limiting block.
8. The size slide opening device of claim 1, wherein: The ejector portion facing the injection cavity is an arc-shaped ejector surface that protrudes into the injection cavity and whose overall shape matches the injection cavity.
9. The size slide opening device of claim 1, wherein: The fixed slide has at least one fixed limiting groove, and the movable slide has at least one movable limiting plate that is inserted into the fixed limiting groove.
