Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a slide insertion and positioning device for a plastic mold. Background Art

[0002] The mold slide helps holes or buttons on the side of the product to be released smoothly during the mold opening and closing process, ensuring product integrity and accuracy. By performing lateral core pulling or parting, as well as resetting, the mold slide solves molding issues such as undercuts and sunken areas on the product, ensuring smooth product removal.

[0003] During the use of injection molds, for some plastic products with specific structural requirements, the traditional injection mold slide structure often suffers from the slide being impacted by the plastic, causing it to deviate from its original position. This results in defective plastic products with features such as step differences, burrs, and uneven glue thickness on both sides. The traditional slide structure is prone to wear and tear. Due to the impact of the plastic during injection molding, the slide is easily misaligned, resulting in step differences and uneven glue thickness on the product. This leads to a high defect rate, increased production time and cost, and reduced production efficiency. Traditional injection mold slide structures often face many difficulties during the molding process, which can easily affect product quality, and therefore require improved design.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-11, this embodiment provides a plastic mold slide insertion and positioning device, including a mold base 1, a slide component 2, and a slide component 2 10, characterized in that: the slide component 1 2 has the same structure as the slide component 2 10 and is centrally symmetrically arranged at both ends of the slide groove of the mold base 1, the slide component 1 2 includes: a slide seat 3, a slide 4, a slide core 1 5 and a slide core 2 6, the front end of the slide core 2 6 is provided with a groove 9, the front end of the slide core 1 5 is provided with a boss 8, the groove 9 and the boss 8 match each other when plugged in, and the two ends of the slide 4 are provided with slide core through holes 7.

[0033] The slide seat 3 is fixedly connected to the slide 4 by bolts; the slide core 1 5 includes a card table and a column, one end of the column is fixedly connected to the card table, and the other end is fixedly connected to the wide side of the boss 8; the aperture of the slide core through hole 7 matches the slide core 1 5 and the slide core 2 6; the slide core 2 6 includes a card table and a column, one end of the column is fixedly connected to the card table, and the other end is provided with the groove 9; the boss 8 is a frustum-shaped boss that is narrow at the top and wide at the bottom, and the groove 9 is a frustum-shaped groove that is wide at the top and narrow at the bottom. The slide core 1 5 and the slide core 2 6 pass through the two slide core through holes 7 of the slide 4 and are pressed and fixed by the slide seat 3.

[0034] Example 2

[0035] See also Figure 12 This embodiment is basically the same as embodiment 1, the difference being that the slide member 2 includes a slide seat 3, a slide 4 and two slide cores 5, and the slide member 2 10 includes a slide seat 3, a slide 4 and two slide cores 6, and the two bosses 8 correspond to the two grooves 9.

[0036] The working principle of this utility model is:

[0037] The utility model designs the front ends of the slider cores 1 5 and 2 6 of the slider components 1 2 and 2 10 into a pair-insertion concave-convex pair-insertion fixing design. When the mold begins to close, the oblique pin allows the slider components 1 2 and 2 10 to move horizontally through the oblique guide column holes during the mold closing process. The slider 4 is fixed to the slider seat 3 by bolts. The slider cores 1 5 and 2 6 pass through the through holes reserved for the slider 4. The bottoms of the slider cores 1 5 and 2 6 are 3 / 4 circle cones. The planes of the bottom cones of the slider cores 1 5 and 2 6 match the planes of the through holes reserved for the slider 4, so that the slider cores 1 5 and 2 6 are fixed to the slider 4. In the process, when the mold is closed, the boss 8 at the front end of the slide core 15 of the slide component 2 is matched with the groove 9 at the front end of the slide core 2 6 of the slide component 2 10, and the boss 8 at the front end of the slide core 15 of the slide component 2 10 is matched with the groove 9 at the front end of the slide core 2 6 of the slide component 2, and is precisely fixed to prevent them from moving. When the mold is in the injection molding state, the plastic fills the mold cavity, which will form a certain impact force. The plug-in design prevents the slide core 1 5 and the slide core 2 6 from being deviated under the impact force of the plastic, producing defective products, and preventing the injection molded product from forming a step difference at the joint of the slides, thereby avoiding uneven glue thickness in the product.

[0038] The above embodiments of the present invention focus on inserting and positioning the groove on the first row position and the convex groove on the second row position through various structural improvement designs, thereby solving the problem that the two sliders of plastic products with complex structures are easily deviated due to the impact force when they collide during molding, so that the injection molded product will not form a step difference at the junction of the rows, avoiding uneven glue thickness of the product, making the quality of the injection molded product more stable, reducing the defective rate, improving production efficiency, improving product quality and production efficiency, extending the service life of the mold rows, and reducing production costs.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
