Description

Technical Field

[0001] This utility model relates to the field of slider mold opening technology, and in particular to an internal slider structure that is easy to assemble and disassemble. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] A slider is a mold component that can slide perpendicular to or at a certain angle to the mold opening and closing direction during the mold opening process. Existing sliders or ejectors require hydraulic cylinders for power. The design of these components involves complex routing between the cylinder and the slider or ejector, resulting in numerous parts and complicated installation and disassembly, which is not conducive to the demands of modern, high-speed production. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide an internal slider structure that is easy to assemble and disassemble. Its overall structure is simple and clear, convenient to use, easy to install and disassemble, and has high mold opening efficiency, effectively improving production efficiency and meeting the needs of rapidly developing production.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] An easily detachable internal slider structure includes a mold for injection molding of an injection molded part, slider assemblies respectively disposed on both sides inside the mold and pressed close to each other, a shovel base disposed between the two slider assemblies and movable up and down inside the mold, and a push post movably disposed within the shovel base and protruding upward inside the mold to eject the injection molded part; the slider assembly includes a mounting block disposed on the inner side wall of the mold, and an internal slider disposed on the mounting block and pressed into the mold, the shovel base being inserted into the mold and applying force to press the internal slider against the side wall of the mold.

[0007] As a further improvement of this utility model, the lower part of the mold is formed with an opening facing the shovel base for insertion and movement, and the slider assembly is disposed on the side of the pressing groove; the mold is provided with an injection cavity for injection molding of the injection molded part, and the top column passes through the pressing groove and the injection cavity in sequence and protrudes into the injection cavity.

[0008] As a further improvement of this utility model, the inner slider has outwardly protruding driving blocks on both sides of one end facing the shovel base, which are inclined from the lower outside to the upper inside. The two sides of the shovel base have slider driving grooves for the driving blocks to be inserted, which are inclined from the lower outside to the upper inside.

[0009] As a further improvement of this utility model, the inner slider has a slider inclined guide surface that extends from the outer bottom to the inner top and matches the inclined angle of the driving block at one end facing the shovel base. The two sides of the shovel base each have a shovel base inclined guide surface that extends from the outer bottom to the inner top and matches the slider driving groove.

[0010] As a further improvement of this utility model, the mounting block is T-shaped in general, and an embedded block is formed on the lower outer side of the inner slider, which is fitted into the T-shaped structure of the mounting block.

[0011] As a further improvement of this utility model, it also includes an elastic member disposed between the mounting block and the inner slider; an elastic mounting groove is formed on the lower outer side of the inner slider for the elastic member to be inserted; one end of the elastic member abuts against the mounting block, and the other end abuts against the inner wall of the tail end of the elastic mounting groove.

[0012] As a further improvement of this utility model, it also includes limiting pins that are horizontally inserted into both sides of the mold, and the upper end of the inner slider has a limiting slot for the limiting pins to pass through and move left and right.

[0013] As a further improvement of this utility model, the upper end of the inner slider is also formed with an outwardly protruding, pressing against the inner wall of the upper part of the pressing movable groove.

[0014] As a further improvement of this utility model, it also includes a push plate disposed at the lower end of the shovel base, wherein the lower end of the top column is fixed inside the push plate and the upper end protrudes into the injection molding cavity.

[0015] The beneficial effects of this utility model are as follows:

[0016] This easily detachable inner slider structure is configured as follows: a mold for injection molding of a part; slider assemblies respectively disposed on both sides inside the mold and pressed close to each other; a shovel base disposed between the two slider assemblies and movable up and down inside the mold; and a push post movably disposed within the shovel base and protruding upward inside the mold to eject the injection molded part. Each slider assembly includes a mounting block disposed on the inner sidewall of the mold and an inner slider disposed on the mounting block and pressed into the mold. The shovel base is inserted into the mold and applies force to press the inner slider against the mold sidewall, causing the inner slider to deform and press against the corresponding sides inside the mold. The shovel base presses and fixes the inner slider. This design effectively prevents the inner slider from moving during injection molding, which could lead to poor injection molding. The upper end of the mold is pressed against the inner slider, causing it to expand outwards and providing sufficient injection space. The ejector pin is inserted into the mold and forms a hook during injection molding. When the mold opens, the ejector pin retracts, following the ejector pin out of the mold. The molded part detaches from the ejector pin, providing position and space for easier mold opening and improving efficiency. Simultaneously, the inner slider presses inwards, disengaging the mold from the slider's pressure. Its upper end returns to its original position under its own elastic restoring force, thus extruding the molded part and completing the mold opening process. The overall process is highly fluid, requiring only up-and-down movement, reducing the need for multi-angle clearance structures between components. It is convenient to use, with high compatibility between components, and a simple structure that is easy to install and disassemble. When not in use or when mold opening is difficult, components can be directly disassembled, facilitating production and improving efficiency, thus meeting the demands of rapid production growth.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," 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 utility model according to the specific circumstances.

[0029] Please refer to Figures 1 to 6This utility model provides an easy-to-assemble and disassemble internal slider structure, including a mold 1 for injection molding of an injection molded part, slider assemblies 2 respectively disposed on both sides of the mold 1 and pressed close to each other, a shovel base 3 disposed between the two slider assemblies 2 and movable up and down within the mold 1, and a push post 4 movably disposed within the shovel base 3 and protruding upward within the mold 1 to eject the injection molded part; the slider assembly 2 includes a mounting block 21 disposed on the inner side wall of the mold 1, and an internal slider 22 disposed on the mounting block 21 and pressed into the mold 1. The shovel base 3 is placed into the mold 1 and applies force to the inner slider 22 against the side wall of the mold 1, causing the inner slider 22 to deform and press against the corresponding sides of the mold 1. The shovel base 3 presses against the inner slider. Block 22 is pressed and fixed to effectively prevent the inner slider 22 from moving during the injection molding process, which could lead to poor injection molding of the injection molded part. The upper end of the mold 1 is pressed by the inner slider 22 and pushed outward, providing sufficient injection space for injection molding. The ejector pin 4 is placed inside the mold 1 and forms a barb when the mold 1 is being injection molded. When the mold is opened, the shovel base 3 retracts and the ejector pin 4 follows the shovel base 3 out of the mold 1. The injection molded part is separated from the ejector pin 4, providing position and space to facilitate mold opening, making the injection molded part easier to open and improving mold opening efficiency. At the same time, the inner slider 22 is squeezed inward, and the mold 1 is freed from the pressure of the inner slider 22. Its upper end is reset under its own elastic restoring force, thereby squeezing out the injection molded part and completing the purpose of opening the injection molded part. The overall process is highly smooth, with activities only requiring up and down movement. This reduces the need for clearance structures between components at multiple angles, making it convenient to use. The components have a high degree of compatibility, and the structure is simple, making it easy to install and disassemble. When not in use or when mold opening is difficult, the components can be directly disassembled, which is beneficial for production. The mold opening efficiency is high, effectively improving production efficiency and meeting the needs of rapidly developing production.

[0030] Regarding the specific structural design of the mold 1, as follows: Figure 2 and Figure 3As shown, the lower part of the mold 1 has an opening facing the shovel base 3 for insertion and movement, forming a pressing groove 11. The slider assembly 2 is disposed on the side of the pressing groove 11. The mold 1 has an injection cavity 12 for injection molding of the part. The top post 4 passes through the pressing groove 11 and the injection cavity 12 in sequence and protrudes into the injection cavity 12. Two sets of slider assemblies 2 are respectively disposed inside the pressing groove 11. When the shovel base 3 is inserted into the pressing groove 11, the shovel base 3 pushes the two sets of inner sliders 22 outwards respectively, causing the inner sliders 22 to press against the pressing groove 11 and exert force on the side wall of the mold 1, causing the upper part of the mold 1 to deform. The injection cavity 12 is expanded within a small range for injection molding of the part. The top post 4 passes through the pressing groove 11 and the injection cavity 12 in sequence and protrudes into the injection cavity 12. When the mold 1 is injection molded, it forms a barb, which is beneficial for subsequent mold opening and improves mold opening efficiency.

[0031] Regarding the specific method by which the shovel base 3 drives the inner slider 22, as follows: Figures 2 to 6 As shown, the inner slider 22 has outwardly protruding driving blocks 221 on both sides of its end facing the shovel base 3, extending inclined inward and upward from the outer bottom. The shovel base 3 has slider driving grooves 31 on both sides for the driving blocks 221 to be inserted, extending inclined inward and upward from the outer bottom. The driving blocks 221 are inserted into the slider driving grooves 31. Under the inclined guiding structure of the driving blocks 221 and the slider driving grooves 31, when the shovel base 3 moves upward and is inserted into the pressing movable groove 11, it pushes the inner slider 22 outward. When the shovel base 3 moves downward and retracts from the pressing movable groove 11, it drives the two sets of inner sliders 22 to press against each other, which is more conducive to extrusion mold opening. Its inclined structure, in addition to its driving function, also achieves a guiding function, making the movement of the inner slider 22 more precise and improving the operational accuracy and efficiency of this inner slider structure.

[0032] In order to better drive the inner slider 22, such as... Figure 2 , Figures 4 to 6As shown, the inner slider 22 has a slider inclined guide surface 222 that extends from the outer bottom to the inner top and matches the inclined angle of the driving block 221 at one end facing the shovel base 3. The two sides of the shovel base 3 each have a shovel base inclined guide surface 32 that extends from the outer bottom to the inner top and matches the slider driving groove 31. When the shovel base 3 is placed into the pressing movable groove 11, the shovel base inclined guide surface 32 at the upper end of the shovel base 3 first contacts the slider inclined guide surfaces 222 of the two sets of inner sliders 22. Under the inclined guiding action of the shovel base inclined guide surface 32 and the slider inclined guide surface 222, the shovel base 3 better presses the inner slider 22 against the mold 1, making the movement of the inner slider 22 more precise, and further improving the operating accuracy and operating efficiency of this inner slider structure.

[0033] The specific method by which the mounting stop 21 limits the inner slider 22 is as follows: Figure 2 , Figures 4 to 6 As shown, the mounting block 21 is T-shaped. An insert block 226 is formed on the lower outer side of the inner slider 22, fitting into the T-shaped structure of the mounting block 21. By inserting the insert block 226 into the T-shaped structure of the mounting block 21, the lower part of the inner slider 22 is limited by the mounting block 21. This prevents the inner slider 22 from being excessively squeezed against the inner wall of the mold 1 when the shovel base 3 is inserted and presses against the movable groove 11, thus avoiding excessive deformation of the mold 1 and preventing precise injection molding of the part. This further ensures the operational accuracy and efficiency of the inner slider 22 structure. Furthermore, the insertion block 226's embedding within the T-shaped structure of the mounting block 21 also makes it easy to detach and install the inner slider 22 from the mounting block 21. When not in use or when mold opening is difficult, the components can be directly disassembled, facilitating production.

[0034] Preferred, such as Figure 2 As shown, in order to make it easier for the inner sliders 22 to move closer to each other in the pressing movement, the inner slider structure also includes an elastic member 5 disposed between the mounting block 21 and the inner slider 22; an elastic mounting groove 223 is formed on the lower outer side of the inner slider 22 for the elastic member 5 to be inserted; one end of the elastic member 5 presses against the mounting block 21, and the other end presses against the inner wall of the tail end of the elastic mounting groove 223, so that when the shovel base 3 is withdrawn, the inner slider 22 moves closer to the pressing movement groove 11 under the elastic force of the elastic member 5, thereby completing the purpose of resetting and extruding the mold 1 and effectively improving the production efficiency of the inner slider 22 structure.

[0035] Preferred, such as Figure 2As shown, the elastic element 5 is a spring, which has good elasticity, strong load-bearing capacity, simple structure, low cost, and good shock absorption capacity, effectively ensuring the operation of the inner slider 22, reducing the production cost of the inner slider structure, and ensuring the service life of the inner slider structure.

[0036] To prevent the inner sliders 22 from getting too close to each other and from being squeezed outwards excessively, such as Figures 1 to 2 , Figures 4 to 6 As shown, the internal slider structure also includes limiting pins 6 horizontally inserted into both sides of the mold 1. The upper end of the internal slider 22 has a limiting slot 224 through which the limiting pin 6 passes and moves left and right. The limiting pin 6 is fixed to the mold 1. When the internal sliders 22 move closer together or outwards within the pressing groove 11, the limiting slot 224 is moved. Because the limiting pin 6 passes through the limiting slot 224, the limiting slot 224 is limited by the stroke of the limiting pin 6, effectively preventing the internal sliders 22 from moving too close together or outwards excessively, thus preventing the internal slider structure from malfunctioning and ensuring the operational accuracy of the internal slider 22 structure. Its overall structure is simple; the limiting pin 6 simply passes through the mold 1. Disassembly is also simple and convenient, requiring only the limiting pin 6 to be pulled out of the mold 1, facilitating disassembly and installation.

[0037] Preferred, such as Figure 2 , Figures 4 to 6 As shown, the upper end of the inner slider 22 is also formed with an outwardly protruding, pressing against the upper inner wall of the pressing movable groove 11. The outwardly protruding structure of the pressing limit block 225 makes it easier to press and support the upper part of the mold 1, so that the mold 1 opens slightly, which is conducive to injection molding and improves the production efficiency of the inner slider 22 structure.

[0038] Preferred, such as Figures 1 to 2 , Figures 4 to 5 As shown, the internal slider 22 structure also includes a push plate 7 disposed at the lower end of the shovel base 3. The lower end of the top column 4 is fixed inside the push plate 7 and the upper end protrudes into the injection molding cavity 12. By providing a push plate 7 at the lower end of the shovel base 3, it is convenient to control the up and down movement of the top column through the push plate 7, which facilitates precise control of the top column position and further improves the operational accuracy of the internal slider 22 structure.

[0039] It should be noted that the easily detachable internal slider structure disclosed in this utility model is an improvement on a specific structure, but the specific control method is not an innovation of this utility model. The springs and other components involved in this utility model can be general standard parts or components known to those skilled in the art, and their structures, principles, and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0040] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
