Application of a slider-driven oscillating structure in submerged injection molds

Abstract

This invention relates to the field of mold manufacturing technology and discloses the application of a slider-driven swing structure in submerged injection molds. The slider-driven swing structure includes an iron part, a swing insert, and a slider. A spring pushes the slider. As the slider moves, when it contacts the swing insert, it pushes the swing insert to move. When the swing insert contacts the iron part, a protruding part on the iron part extends into a groove at the top of the swing insert. If there is an undercut on the iron part, the undercut will be stuck in the groove at the top of the swing insert. As the swing insert moves towards the iron part, when the protruding part on the iron part extends beyond the groove of the swing insert, it continues to extend into the corresponding groove on the slider until the protruding part on the iron part is completely fitted with the corresponding groove on the swing insert and the slider. This seals the swing insert, slider, and iron part, solving the problem that products with undercuts cannot directly move along the slider.

Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, specifically to the application of a slider-driven swing structure in submerged injection molds. Background Technology

[0002] In recent years, with the rapid development of various industries, the requirements for products have been continuously increasing. The pursuit of small size and high performance products has been growing. The design of products such as automobiles, home appliances, industrial products, automation products, new robots, and children's toys has become more diversified and complex, which has led to increasingly higher requirements for mold forming. At present, most common or frequently used plastic parts are processed and formed using injection molds. Injection molds are mainly composed of front molds, rear molds, and ejection mechanisms. Under normal circumstances, sealing the sides of metal parts inside the mold is quite difficult. It is not only easily limited by the fit between the metal parts and the mold forming plate components, but also by the cross-sectional design of the product. Therefore, the existing side sealing of metal parts inside the mold is prone to overflow and the formation of burrs, which need to be removed later, consuming manpower and resources and increasing production costs. Summary of the Invention

[0003] The purpose of this invention is to provide an application of a slider-driven swing structure in an injection mold, so as to improve product quality, compensate for dimensional tolerance defects of embedded parts, improve product appearance, and optimize costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an application of a slider-driven swing structure in an injection mold, comprising a slider-driven swing structure, wherein the slider-driven swing structure includes an iron part, a swing insert, and a slider, the iron part is located on the right side of the swing insert, the swing insert is located on the right side of the slider, and an undercut is fixedly provided at the bottom of the iron part.

[0005] Preferably, the left end of the iron piece extends into the groove at the top of the swing insert, and the buckle is locked in the groove on the swing insert, using the swing insert to lock the buckle on the iron piece.

[0006] Preferably, the left end of the iron piece passes through the swing insert and extends into the slider, and at this time the bottom of the iron piece is completely inside the groove at the top of the swing insert, so as to avoid the upper part of the iron piece protruding and causing the slider to be unable to fit with the swing insert.

[0007] Preferably, the top groove of the swing insert has a reserved space that corresponds to the tolerance defects of the iron part, so as to avoid the iron part being unable to fit with the swing insert due to tolerance defects.

[0008] Preferably, a spring is provided on the left side of the slider, and the spring pushes the slider to move, thereby squeezing the slider inward and pressing the slider onto the swing insert.

[0009] Preferably, the slider and the oscillating insert are located in the mold cavity between the rear mold and the front mold, so that the slider and the oscillating insert can form a good seal with the iron part.

[0010] Preferably, the slider is a floating slider, and the shape and size of the slider correspond to the swing insert, so that the slider can fit with the swing insert without any corner gaps. The shape and size of the swing insert correspond to the iron part, so that a sealant can be formed when the swing insert fits with the iron part.

[0011] Preferably, the slider-driven swing structure is used in the application of embedded part encapsulation positioning technology during mold forming to improve product quality, compensate for dimensional tolerance defects of embedded parts, improve product appearance, and optimize costs.

[0012] This invention provides an application of a slider-driven oscillating structure in an injection molding die. This slider-driven oscillating structure offers the following advantages: A spring pushes the slider. As the slider moves, it contacts the oscillating insert, which in turn pushes the insert to move. When the oscillating insert contacts the metal part, a protruding part on the metal part extends into a groove at the top of the oscillating insert. If there is an undercut on the metal part, the undercut will be locked in the groove at the top of the oscillating insert. As the oscillating insert moves towards the metal part, the protruding part on the metal part extends beyond the groove of the oscillating insert and continues to extend into the corresponding groove on the slider until the protruding part on the metal part is completely fitted with the corresponding groove on the oscillating insert and the slider. This seals the oscillating insert, slider, and metal part, solving the problem of products with undercuts not being able to directly slide along the slider. It also avoids the problem of burrs forming on the surface of the product after molding due to tolerance differences and gaps in the metal part. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Please see Figure 1-3 The present invention provides a technical solution: an application of a slider-driven swing structure in an injection mold, comprising a slider-driven swing structure, the slider-driven swing structure comprising an iron part 1, a swing insert 2, and a slider 3, the iron part 1 being located to the right of the swing insert 2, the swing insert 2 being located to the right of the slider 3, and an undercut 4 being fixedly provided at the bottom of the iron part 1;

[0021] The left end of the iron part 1 extends into the groove at the top of the swing insert 2. The undercut 4 is secured in the groove on the swing insert 2. The swing insert 2 holds the undercut 4 on the iron part 1 in place, preventing the slider 3 from being unable to move due to the undercut 4 on the iron part 1. This would prevent the slider 3 from forming a seal with the iron part 1, resulting in large dimensional tolerance defects in the embedded part. After the left end of the iron part 1 passes through the swing insert 2, it extends into the slider 3. At this time, the undercut 4 at the bottom of the iron part 1 is completely located in the groove at the top of the swing insert 2. This prevents the upper part of the undercut 4 from protruding, which would prevent the slider 3 from fitting properly with the swing insert 2, thus avoiding gaps between the slider 3 and the swing insert 2. The slider 3 is a floating slider, and its shape and size correspond to the swing insert 2, allowing the slider 3 to fit properly without any corner gaps that would prevent the slider 3 from horizontally pushing the swing insert 2. The shape and size of the insert 2 correspond to the iron part 1, so that when the oscillating insert 2 and the iron part 1 are attached, a sealant can be formed, improving the sealing performance and preventing burrs from being generated on the embedded part during molding. The groove at the top of the oscillating insert 2 has a reserved space, which corresponds to the tolerance defects of the iron part 1, so as to prevent the iron part 1 from being unable to fit with the oscillating insert 2 due to the tolerance defects of the iron part 1. A spring is provided on the left side of the slider 3, and the spring pushes the slider 3 to move, which is used to squeeze the slider 3 inward and press the slider 3 onto the oscillating insert 2, so that the oscillating insert 2 is tightly pressed onto the iron part 1. The slider 3 and the oscillating insert 2 are located in the mold cavity between the rear mold and the front mold, so that the slider 3 and the oscillating insert 2 can form a sealant with the iron part 1 well, avoiding the situation where the undercut 4 on the iron part 1 cannot directly move the slider 3, causing the iron part 1 to generate burrs on its surface after molding due to tolerance differences and gaps.

[0022] In the application of this slider-driven swing structure in injection molds, the front and rear molds are first separated. Then, the iron part 1 is embedded into the mold cavity, and the corresponding swing insert 2 is removed. The swing insert 2 is placed in front of the slider 3 placed in the mold cavity. The slider 3 is pushed by a spring. As the slider 3 moves, when the slider 3 contacts the swing insert 2, it will push the swing insert 2 to move. When the swing insert 2 moves and contacts the iron part 1, the protruding part on the iron part 1 will extend into the groove at the top of the swing insert 2. If there is a buckle 4 on the iron part 1, the buckle 4 will be stuck in the groove at the top of the swing insert 2. As the swing insert 2 moves towards the iron part 1, when the protruding part on the iron part 1 extends into the groove at the top of the swing insert 2... After exiting the groove, it will continue to extend into the corresponding groove on the slider 3 until the protruding part on the iron part 1 is completely fitted with the corresponding groove on the swing insert 2 and the slider 3. Then the swing insert 2, the slider 3 and the iron part 1 are sealed. Then the mold is closed and injection molding is performed. This solves the problem that the product with undercuts cannot directly move along the slider 3. It avoids the problem that the iron part 1 has undercuts 4 and cannot directly move along the slider 3. This causes the iron part 1 to have tolerance differences and gaps, resulting in burrs on the surface of the product after molding. After the injection molding is completed, the front mold and the rear mold are opened, the spring push on the slider 3 is released, so that the slider 3 no longer pushes the swing insert 2. Then the swing insert 2 is pulled to separate the swing insert 2 from the iron part 1, and the iron part 1 can be removed.
