Description

Technical Field

[0001] This utility model relates to a mechanism for splitting on opposite sides. Background Technology

[0002] Against the backdrop of the booming development of the modern new energy vehicle industry, the trend of product diversification and complexity is becoming increasingly prominent. Various internal undercut and lateral groove structures are emerging in large numbers, posing unprecedented challenges to the demolding mechanisms of injection molds. Traditional inclined ejectors and slides are no longer sufficient to meet the demands of high-precision and high-efficiency production; therefore, an anisotropic side parting mechanism is proposed to address these issues. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing designs by providing a mechanism for parting in opposite directions. This mechanism is flexible and compact, and is suitable for complex composite undercut molding of products and demolding in different directions in confined spaces.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mechanism for splitting on opposite sides, comprising a fixed base, an inclined guide post, an inclined slider, a guide block, a sliding body, and a straight slider; The fixed base has an oblique hole for installing and fixing the oblique guide post; the oblique guide post is used to drive the oblique slider and straight slider below the fixed base to move, so as to realize the demolding of the product with side undercut. The straight slider is located below the fixed base and is used for lateral undercutting of the product exterior, achieving core pulling through lateral movement; The inclined slider is installed in the straight slider and is located between the straight slider and the fixed seat. It is used for lateral undercutting forming inside the product. Through an inclined angle, it can simultaneously complete longitudinal ejection and lateral retraction during the movement. The guide block is located on one side of the straight slider and is used to precisely define the tilt angle required for the internal undercut molding of the product. The sliding body is disposed inside the guide block and the straight slider, and is used for internal undercut molding of the product and demolding during movement.

[0005] Preferably, the straight slider is slidably connected to the inclined slider via a side-connected inclined guide rail; the inclined guide rail is used to control the movement distance of the inclined slider in the straight slider, so that the inclined slider moves at a defined angle.

[0006] Preferably, it also includes a spring, which is disposed between the straight slider and the inclined slider to create a time difference between the inclined slider and the straight slider during movement, thereby controlling the inclined slider to move before the straight slider.

[0007] Preferably, a locking block is connected to one side of the fixed base, and a wear-resistant plate is connected to the side of the locking block near the inclined slider and the straight slider.

[0008] Preferably, a first pressure block and a second pressure block are respectively provided on the front and rear sides of the fixed base to control the linear motion of the straight slider.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: In this non-directional side-parting mechanism, the straight slider handles the lateral undercut on the outside of the product, achieving core pulling through lateral movement; the inclined slider handles the lateral undercut on the inside of the product, simultaneously completing longitudinal ejection and lateral retraction during movement through an inclined angle. The inclined slider cleverly utilizes the internal space of the straight slider to conceal the inclined slider within the valuable mold space, avoiding additional external space occupation. This results in a more compact overall mold size, enabling the production of larger products on smaller injection molding machines and reducing equipment investment costs. With its unique motion characteristics, it can achieve complex demolding actions within limited mold space, becoming an indispensable key component in precision injection mold design.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1-2As shown, the anti-directional side parting mechanism is used for complex composite undercut molding of products and for demolding in different directions in confined spaces; it includes a fixed base 301, an inclined guide post 302, an inclined slider 510, an inclined guide block 511, a sliding body 512, and a straight slider 403; the fixed base 301 has an inclined hole for mounting and fixing the inclined guide post 302; the inclined guide post 302 is used to drive the inclined slider 510 and the straight slider 403 below the fixed base 301 to move, so as to realize the demolding of the product with lateral undercut; Specifically, the straight slider 403 is positioned below the fixed base 301 and is used for lateral undercutting of the product's exterior, achieving core pulling through lateral movement. The inclined slider 510 is installed within the straight slider 403, located between the straight slider 403 and the fixed base 301, and is used for lateral undercutting of the product's interior. Through an inclined angle, it simultaneously performs longitudinal ejection and lateral retraction during movement. The straight slider 403 is slidably connected to the inclined slider 510 via a side-connected inclined guide rail 601. The inclined guide rail 601 controls the movement distance of the inclined slider 510 within the straight slider 403, ensuring the inclined slider 510 moves at a defined angle. A spring 602 is also included, positioned between the straight slider 403 and the inclined slider 510, creating a time difference between their movements to control the inclined slider 510 to move before the straight slider 403. A first pressure block 401 and a second pressure block 402 are respectively positioned on the front and rear sides of the fixed base 301 to control the linear movement of the straight slider 403.

[0014] Specifically, the guide angle block 511 is set on one side of the straight slider 403 to precisely define the tilt angle required for the internal undercut molding of the product; the slider 512 is set inside the guide angle block 511 and the straight slider 403 for internal undercut molding of the product and demolding during movement.

[0015] Specifically, a locking block 303 is connected to one side of the fixed base 301, and a wear-resistant plate 304 is connected to the side of the locking block 303 near the inclined slider 510 and the straight slider 403.

[0016] Specifically, an angled hole is designed on the fixed base 301 to fix the angled guide post 302. The angle can be set as needed, with a typical angle range of 8°-25°. After the injection molding machine opens the mold, the angled guide post 302 drives the slider to move outward, completing the demolding of the product's external lateral undercut. Specifically, the straight slider 403, as the basic carrier of the entire mechanism, possesses excellent wear resistance and rigidity. Its shape is "T"-shaped and is customized according to the specific product structure and demolding requirements. The pressure block 401 presses on the "T" shape, controlling the fit clearance of the straight slider 403 in the "Z" direction, so that the straight slider 403 moves in a linear direction.

[0017] Specifically, the straight slide block 403 has a precise guide groove inside for mounting the angled slide block 510. The direction and distance of movement of the angled slide block 510 within the straight slide block 403 are controlled by a spring 602 and an angled guide rail 601, ensuring that the angled slide block 510 moves at a defined angle and slides smoothly in a specific direction during mold opening and closing. The angle of the angled slide block 510 is a crucial design parameter, determining the magnitude of the ejection force and the proportion of the horizontal component force. Generally, a larger angle results in a larger ejection force, but also a larger horizontal component force, which may cause the slide block to bear greater lateral pressure, affecting the mold's service life and stability. Conversely, a smaller angle results in a relatively weaker ejection force, but a reduced horizontal component force, which helps protect the slide block and the mold. Specifically, the guide block 511 is a key component that directly affects the product. Its surface is hardened to improve hardness and smoothness, and reduce frictional resistance. The angled hole in the middle matches the tilt angle required for the internal undercutting of the product.

[0018] Specifically, the sliding body 512 is installed in the inclined hole of the guide block 511 and connected to the inclined slider 510. It is used for internal undercut molding of the product and demolding during movement. The locking block 303 and the wear-resistant plate 304 are used together for the reset and locking of the inclined slider 510 and the straight slider 403. The contact area between the wear-resistant plate 304 and the straight slider 403 is larger than the forming area at the front end to ensure sufficient locking force. Its hardness is quenched to HRC50°~52° to reduce the coefficient of friction when the locking block 303 resets.

[0019] This non-directional parting mechanism uses a straight slider to handle external lateral undercuts, achieving core pulling through lateral movement. The angled slider handles internal lateral undercuts, simultaneously performing longitudinal ejection and lateral retraction during movement at an angle. Ingeniously utilizing the internal space of the straight slider to conceal the angled slider within the valuable mold space avoids additional external space requirements. This results in a more compact overall mold size, enabling the production of larger products on smaller injection molding machines and reducing equipment investment costs. Its unique motion characteristics allow for complex demolding actions within limited mold space, making it an indispensable key component in precision injection mold design.
