The mounting frame is used to support the injection module and slide into the cavity for fixation. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a core-pulling mechanism for inserting blocks in a split-type sorting trash can mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A core-pulling mechanism for a split-type sorting trash can mold includes a first upper mold, a second upper mold, a first lower mold, and a second lower mold arranged sequentially from top to bottom. A middle insert is embedded in the second lower mold, with the top of the middle insert penetrating through the first lower mold and inserted between the second lower mold and the first lower mold. A core-pulling mechanism for the middle insert is provided between the second upper mold and the first lower mold, and the middle insert has an indentation on the side facing the core-pulling mechanism. Internal core-pulling mechanisms are also symmetrically arranged on both sides of the first lower mold.

[0006] In the above-mentioned split-type sorting garbage bin mold insert core pulling mechanism, the insert core pulling mechanism includes a bottom slide seat slidably disposed on the first lower mold and a translation component connected to the bottom slide seat. The bottom slide seat is provided with an insert seat at its top, and the inner end of the insert seat is provided with a molded insert that is inserted into the inner recess.

[0007] In the above-mentioned split-type sorting garbage bin mold insert core-pulling mechanism, the bottom slide, insert seat and molding insert are integrally formed.

[0008] In the above-mentioned split-type sorting garbage bin mold insert core-pulling mechanism, the translation component includes a driver mounting base fixed on the outer side wall of the first lower mold, a translation driver is fixedly connected to the driver mounting base, and the output shaft end of the translation driver is connected to the bottom slide.

[0009] In the above-mentioned split-type sorting garbage bin mold insert core-pulling mechanism, the output shaft end of the translation driver is fixedly connected to a connector with a T-shaped cross section, and the outer end of the bottom slide is vertically provided with a connecting groove with a T-shaped cross section.

[0010] In the above-mentioned split-type sorting garbage bin mold insert core pulling mechanism, the first lower mold is detachably fixed with two T-shaped limit rails by several bolts, and the bottom slide is recessed inward and provided with a limit groove that slides in cooperation with the limit rails.

[0011] In the above-mentioned split-type sorting garbage bin mold insert core pulling mechanism, a limiting pressure plate is detachably fixed on the inner side wall of the first lower mold on both sides of the bottom slide by several bolts, and the bottom of the limiting pressure plate abuts against the top of the bottom slide.

[0019] like Figures 1-6 As shown, a split-type sorting trash can mold insert core-pulling mechanism includes a first upper mold 1, a second upper mold 2, a first lower mold 3, and a second lower mold 4 arranged sequentially from top to bottom. The second lower mold 4 is provided with a middle insert 5, the top of which passes through the first lower mold 3 and is inserted between the second lower mold 4 and the first lower mold 3. An insert core-pulling mechanism 6 that cooperates with the middle insert 5 is provided between the second upper mold 2 and the first lower mold 3. The middle insert 5 is provided with an indentation 7 on the side facing the insert core-pulling mechanism 6. The first lower mold 3 is also symmetrically provided with built-in side core-pulling mechanisms 8 on both sides.

[0020] In this invention, the intermediate insert and the insert core-pulling mechanism work together to specifically adapt to the concave side structure of the trash can. At the same time, the built-in side core-pulling mechanisms symmetrically arranged on both sides of the first lower mold assist in molding and core-pulling from the side. This design forms a multi-directional collaborative core-pulling mode, which effectively solves the problem of demolding obstruction of the concave side trash can and improves the smoothness and efficiency of demolding.

[0021] Specifically, the insert core-pulling mechanism 6 includes a bottom slide 9 slidably mounted on the first lower mold 3 and a translation component connected to the bottom slide 9. The bottom slide 9 has an insert seat 10 at its top, and a molded insert 11 protrudes from the inner end of the insert seat 10 and is inserted into the recess 7. The insert core-pulling mechanism drives the bottom slide to slide via the translation component, causing the molded insert on the insert seat to precisely insert into or detach from the recess of the middle insert. The matching design between the molded insert and the recess ensures the molding accuracy of the concave structure of the trash can. The translational core-pulling method avoids scratch damage to the product during demolding, further optimizing the stability of the demolding process and the product qualification rate.

[0022] Preferably, the bottom slide 9, the insert seat 10, and the molding insert 11 are integrally molded. The integral molding design of the bottom slide, the insert seat, and the molding insert enhances the overall structural strength and rigidity of the core-pulling mechanism, reduces molding errors caused by assembly gaps, makes the core-pulling action more synchronized, avoids the relative displacement between components affecting the molding quality of the concave structure of the trash can, and at the same time improves the durability of the mechanism and reduces the maintenance frequency.

[0023] Specifically, the translation assembly includes a driver mounting base 12 fixed on the outer side wall of the first lower mold 3. A translation driver 13 is fixedly connected to the driver mounting base 12, and the output shaft end of the translation driver 13 is connected to the bottom slide 9. The translation assembly fixes the translation driver through the driver mounting base, directly driving the movement of the bottom slide, realizing the power and precise control of the core pulling action. This design replaces the traditional manual core pulling, improves the core pulling efficiency and action consistency, avoids uneven core pulling force or positional deviation caused by manual operation, and ensures a stable and controllable demolding process.

[0024] Those skilled in the art should understand that the translation actuator can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.

[0025] Preferably, a T-shaped connector 14 is fixedly connected to the end of the output shaft of the translation driver 13, and a T-shaped connecting groove 15 is vertically provided through the outer end of the bottom slide 9. The T-shaped connector of the translation driver output shaft and the T-shaped connecting groove of the bottom slide cooperate to achieve quick disassembly and assembly and a stable connection between the two. This structure ensures the reliability of power transmission, facilitates the maintenance and replacement of the driver, reduces equipment downtime for maintenance, and improves overall production efficiency.

[0026] Specifically, two T-shaped limiting rails 16 are detachably fixed to the first lower mold 3 by several bolts. The bottom slide 9 has a limiting groove 17 that slides inward at its bottom and engages with the limiting rails 16. The T-shaped limiting rails on the first lower mold and the limiting grooves on the bottom slide provide precise guidance for the translation of the bottom slide. This design limits the lateral displacement of the slide, ensures that the molding insert can be accurately aligned with the concave part of the middle insert, improves molding accuracy, reduces sliding friction loss, and extends the service life of the mechanism.

[0027] Specifically, limiting plates 18 are detachably fixed to the inner walls of the first lower mold 3 on both sides of the bottom slide 9 by several bolts. The bottom of the limiting plates 18 abuts against the top of the bottom slide 9. The limiting plates on both sides of the bottom slide abut against the top of the slide, forming a vertical limiting constraint. This structure prevents the bottom slide from moving up and down during the core pulling process, ensuring smooth core pulling and avoiding the impact of slide displacement on product molding quality, thus further enhancing the stability of the mechanism operation.

[0028] Preferably, the outer side of the insert base 10 is provided with an inclined guide surface 19, and the top of the insert base 10 is flush with the upper surface of the second upper mold 2. The inclined guide surface on the outer side of the insert base facilitates accurate alignment during mold closing, reduces mold closing resistance and component collision damage; the design that the top of the insert base is flush with the upper surface of the second upper mold ensures the overall sealing of the mold after mold closing, avoids overflow during injection molding, and improves product molding quality.

[0029] Specifically, the built-in side core-pulling mechanism 8 includes a block mounting portion 20 disposed on the inner side wall of the first lower mold 3. The bottom of the block mounting portion 20 is recessed inwardly and has a block mounting groove 21. A side block 22 is slidably connected in the block mounting groove 21. The inner end of the side block 22 abuts against the side wall of the middle block 5. An inclined drive rod 24 inserted into the side block 22 is fixedly connected to the second upper mold 2. The built-in side core-pulling mechanism drives the side block to slide in the block mounting groove through the inclined drive rod. The side block abuts against the side wall of the middle block to achieve lateral forming. This design is designed to assist in the forming of complex side structures of garbage cans. The inclined drive core-pulling can adapt to the lateral demolding requirements, avoid the side structure from hindering demolding, and improve the comprehensiveness and smoothness of demolding.

[0030] Specifically, upper pressure plates 23 are detachably fixed to both sides of the side insert 22 by several bolts, with the bottom of the upper pressure plates 23 abutting against the top of the side insert 22. The upper pressure plates on both sides of the side insert abut against the top of the side insert, forming a longitudinal limit on the side insert. This structure prevents the side insert from shifting up and down during sliding, ensures the fitting accuracy between the side insert and the middle insert, guarantees the forming quality of the side of the trash can, and enhances the structural stability of the side core-pulling mechanism, reducing component wear.

[0031] The working principle of this utility model is as follows: through the cooperation of the intermediate insert and the insert core-pulling mechanism, it is specifically adapted to the concave structure of the side of the trash can. At the same time, the built-in side core-pulling mechanisms symmetrically arranged on both sides of the first lower mold assist in the molding and core-pulling from the side. This design forms a multi-directional collaborative core-pulling mode, effectively solving the problem of demolding obstruction of the concave side trash can, and improving the smoothness and efficiency of demolding. The insert core-pulling mechanism drives the bottom slide to slide via a translation component, causing the molded insert on the insert seat to precisely insert into or detach from the concave part of the middle insert. The matching design between the molded insert and the concave part ensures the molding accuracy of the concave structure of the trash can. The translational core-pulling method avoids scratch damage to the product during demolding, further optimizing the stability of the demolding process and the product qualification rate. The integrated design of the bottom slide, insert seat, and molded insert enhances the overall structural strength and rigidity of the core-pulling mechanism, reducing molding errors caused by assembly gaps. This design makes the core-pulling action more synchronized, avoiding the impact of relative displacement between components on the molding quality of the concave structure of the trash can, while improving the durability of the mechanism and reducing maintenance frequency. The translation component fixes the translation driver through the driver mounting seat, directly driving the movement of the bottom slide, realizing the power and precise control of the core-pulling action. This design replaces the traditional manual core-pulling, improving core-pulling efficiency and action consistency, avoiding uneven core-pulling force or positional deviation caused by manual operation, and ensuring a stable and controllable demolding process. The T-shaped connector of the translation driver output shaft and the T-shaped connecting groove of the bottom slide are matched. This design allows for quick assembly and disassembly, as well as a secure connection between the two components. While ensuring reliable power transmission, it also facilitates the maintenance and replacement of the drive unit, reducing downtime and improving overall production efficiency. The T-shaped limiting track on the first lower mold slides in conjunction with the limiting groove on the bottom slide, providing precise guidance for the translation of the bottom slide. This design limits the lateral displacement of the slide, ensuring that the molding insert accurately aligns with the concave part of the middle insert, improving molding accuracy, reducing sliding friction loss, and extending the service life of the mechanism. The limiting pressure plates on both sides of the bottom slide abut against the top of the slide, forming vertical limiting constraints. This structure prevents the bottom slide from moving up and down during core pulling, ensuring smooth core pulling and avoiding impact on product molding quality due to slide displacement, further enhancing the stability of the mechanism. The inclined guide surface on the outer side of the insert seat facilitates precise alignment during mold closing, reducing mold closing resistance and component collision damage. The design of the top of the insert seat being flush with the upper surface of the second upper mold ensures the overall sealing of the mold after mold closing, preventing overflow during injection molding and improving product molding quality. The built-in side core-pulling mechanism drives the side insert to slide within the insert mounting slot via an inclined drive rod. The side insert abuts against the side wall of the middle insert to achieve lateral forming. This design assists in forming the complex side structure of the trash can. The inclined drive core-pulling mechanism can adapt to the lateral demolding requirements, avoid the side structure from hindering demolding, and improve the completeness and smoothness of demolding. The upper pressure plates on both sides of the side insert abut against the upper part of the side insert, forming a longitudinal limit on the side insert. This structure prevents the side insert from shifting up and down during sliding, ensures the fitting accuracy between the side insert and the middle insert, guarantees the forming quality of the trash can side, and enhances the structural stability of the side core-pulling mechanism, reducing component wear.
