Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a sliding block built-in side inclined core pulling mechanism for logistics turnover box molds. Background Technology

[0002] Molds are essential process equipment in modern industrial production, meeting the needs of large-scale industrial manufacturing. Injection molds are tools used to produce plastic products, giving them a 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 under high pressure into a mold cavity using an injection molding machine, followed by cooling and solidification to obtain the molded product. Plastic turnover boxes are generally produced through injection molding. However, existing turnover box molds have independent lifting mechanisms and side core-pulling components that cannot be linked. This leads to misalignment and interference between the upper mold plate and the side core-pulling components when the mold is closed again after opening.

[0003] For example, a Chinese patent discloses a demolding mechanism for a plastic turnover box mold [Application No.: 201020593745.0], including an upper mold plate and a lower mold plate. A flow channel plate is connected to the lower part of the upper mold plate, and the flow channel plate is connected to a cavity plate. A cavity insert is installed inside the cavity plate. A core plate is installed on the lower mold plate, and a core insert is installed inside the core plate. A front reinforcing rib slider, a rear reinforcing rib slider, a left reinforcing rib slider, and a right reinforcing rib slider are respectively provided on the four sides of the core plate. The core insert interacts with the front, rear, left, and right reinforcing rib sliders and the mold plate... Between the cavity inserts are formed turnover boxes, and the four sides of the turnover box are reinforced with ribs. The left and right sides of the turnover box are provided with handle holes. The feature is that the left and right ends of the front and rear reinforcing rib sliders are respectively equipped with linkage blocks, and each linkage block is movably connected to the left and right reinforcing rib sliders. The front and rear reinforcing rib sliders are respectively equipped with hydraulic cylinders, and the piston rods of the hydraulic cylinders are connected in the cavity plate. The four sides of the cavity plate are respectively equipped with inclined guide posts, which pass through the cavity plate and the front, rear, left and right reinforcing rib sliders. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a side-mounted oblique core-pulling mechanism with a built-in slider for logistics turnover box molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sliding block-type side-angled core-pulling mechanism for a logistics turnover box mold includes an upper template and a lower template. A linked outer insert structure is provided between the upper template and the lower template. A forming cavity is provided between the upper template, the lower template, and the linked outer insert structure. The linked outer insert structure includes two opposing front and rear side core-pulling inserts and two opposing left and right side core-pulling inserts, which together form a rectangle. An outer core-pulling drive assembly connected to the front and rear side core-pulling inserts and the left and right side core-pulling inserts is provided on the upper template. A linked drive assembly is also provided between the linked outer insert structure and the upper template.

[0007] In the above-mentioned sliding block built-in side inclined core-pulling mechanism of logistics turnover box mold, the linkage drive component includes two inclined linear drivers. The output shaft ends of the linear drivers are connected to the upper template through a sliding push-pull structure. The linear drivers are fixed on the left and right side core-pulling inserts through driver mounting seats.

[0008] In the above-mentioned sliding block built-in side inclined core pulling mechanism of the logistics turnover box mold, the sliding push-pull structure includes a connecting seat fixed on the upper template, and a push-pull groove is provided at the bottom of the connecting seat. The output shaft end of the linear driver is fixedly connected to a T-shaped slider inserted into the push-pull groove, and the cross section of the push-pull groove is T-shaped.

[0009] In the above-mentioned sliding block built-in side inclined core pulling mechanism of logistics turnover box mold, a linkage rod is horizontally arranged between the front and rear core pulling blocks and the left and right core pulling blocks, and the linkage rod slides with the front and rear core pulling blocks and the left and right core pulling blocks. The front and rear core pulling blocks and the left and right core pulling blocks are provided with linkage rod mounting slides.

[0010] In the above-mentioned sliding block built-in side inclined core-pulling mechanism of logistics turnover box mold, one end of the linkage rod is fixed in the linkage rod mounting slide on the left and right side core-pulling blocks by several bolts, and the other end of the linkage rod is movably connected to the linkage rod mounting slide on the front and rear side core-pulling blocks.

[0011] In the above-mentioned logistics turnover box mold slider built-in side inclined core pulling mechanism, the external core pulling drive assembly includes a drive rod that is inclinedly fixed on the upper template. The drive rod is inclinedly inserted into the drive rod groove in the front and rear side core pulling inserts and the left and right side core pulling inserts.

[0012] In the above-mentioned sliding block built-in side inclined core pulling mechanism of the logistics turnover box mold, the bottom of the upper template is fixedly connected to the upper insert, the bottom of the upper insert is connected to the molding cavity, and the upper insert is detachably connected to the upper template by several screws.

[0013] In the above-mentioned logistics turnover box mold slider built-in side inclined core pulling mechanism, the upper template is provided with a multi-point glue injection assembly connected to the molding cavity.

The linkage drive assembly can move synchronously with the left and right core-pulling inserts to realize the linkage between the upper template and the linkage outer insert structure, so as to prevent interference between the outer core-pulling drive assembly and the linkage outer insert structure when the mold is closed again.

[0018] 2. The synchronous operation of the two linear actuators can push the upper template upward. The upward movement of the upper template can drive the front and rear core-pulling inserts and the left and right core-pulling inserts to move synchronously away from the molding cavity through the external core-pulling drive assembly. The movement of the left and right core-pulling inserts can drive the linear actuators connected to the upper template through the sliding push-pull structure to move outward.

Detailed Implementation

[0025] like Figures 1-4 As shown, a sliding block-type side-angled core-pulling mechanism for a logistics turnover box mold includes an upper template 1 and a lower template 2. A linkage-type outer insert structure 3 is provided between the upper template 1 and the lower template 2. A forming cavity 4 is provided between the upper template 1, the lower template 2, and the linkage-type outer insert structure 3. The linkage-type outer insert structure 3 includes two opposing front and rear side core-pulling inserts 5 and two opposing left and right side core-pulling inserts 6. The two front and rear side core-pulling inserts 5 and the two left and right side core-pulling inserts 6 together form a rectangle. An outer core-pulling drive assembly connected to the front and rear side core-pulling inserts 5 and the left and right side core-pulling inserts 6 is provided on the upper template 1. A linkage drive assembly 7 is also provided between the linkage-type outer insert structure 3 and the upper template 1.

[0026] In this invention, the linkage drive assembly 7 can drive the upper template to rise and fall vertically. When the upper template moves upward, it can drive the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 to move synchronously away from the molding cavity through the outer core-pulling drive assembly. The linkage drive assembly 7 can move synchronously with the left and right core-pulling inserts to realize the linkage between the upper template and the linkage outer insert structure 3, so as to prevent interference between the outer core-pulling drive assembly and the linkage outer insert structure 3 when the mold is closed again.

[0027] Specifically, the linkage drive assembly 7 includes two inclined linear actuators 8. The output shaft ends of the linear actuators 8 are connected to the upper template 1 via a sliding push-pull structure. The linear actuators 8 are fixed to the left and right side core-pulling inserts 6 via actuator mounting bases 9. The synchronous operation of the two linear actuators can push the upper template upward. The upward movement of the upper template can drive the front and rear side core-pulling inserts 5 and the left and right side core-pulling inserts 6 to move synchronously away from the molding cavity through the external core-pulling drive assembly. The movement of the left and right side core-pulling inserts 6 can drive the linear actuators 8 connected to the upper template 1 via the sliding push-pull structure to move outward.

[0028] Those skilled in the art will understand that a linear actuator can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.

[0029] Specifically, the sliding push-pull structure includes a connecting seat 10 fixed on the upper template 1. The bottom of the connecting seat 10 is inclinedly provided with a push-pull groove 11. The output shaft end of the linear driver 8 is fixedly connected to a T-shaped slider 12 inserted into the push-pull groove 11. The push-pull groove 11 has a T-shaped cross-section. When the left and right side core-pulling inserts 6 move, they can drive the linear driver 8 to move via the driver mounting seat 9. When the linear driver moves, the T-shaped slider can move within the push-pull groove to maintain the connection between the linear driver and the connecting seat.

[0030] Specifically, a linkage rod 13 is horizontally arranged between the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6, and the linkage rod 13 slides in cooperation with the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6. The front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 are provided with linkage rod mounting slides 14. By setting the linkage rod, the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 can move synchronously and maintain the connection between the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6.

[0031] Specifically, one end of the linkage rod 13 is fixed to the linkage rod mounting slide 14 on the left and right side core-pulling blocks 6 by several bolts, and the other end of the linkage rod 13 is movably connected to the linkage rod mounting slide 14 on the front and rear side core-pulling blocks 5. The connection between one end of the linkage rod and the left and right side core-pulling blocks by bolts, and the movable connection between the other end and the front and rear side core-pulling blocks 6, not only maintains the front and rear side core-pulling blocks 5 and the left and right side core-pulling blocks 6, but also prevents the linkage rod from falling off.

[0032] Specifically, the external core-pulling drive assembly includes a drive rod 15 that is tilted and fixed on the upper template 1. The drive rod 15 is tilted and inserted into the drive rod groove 16 within the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6. When the upper template moves upward, the drive rod can drive the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 to move away from the molding cavity to achieve core pulling.

[0033] Preferably, an upper insert 17 is fixedly connected to the bottom of the upper template 1. The bottom of the upper insert 17 is connected to the molding cavity 4, and the upper insert 17 is detachably connected to the upper template 1 by several screws. The detachable upper insert reduces replacement costs when the mold is damaged.

[0034] Preferably, a multi-point injection assembly connected to the molding cavity 4 is provided on the upper side of the upper mold plate 1. The multi-point injection assembly includes an injection liquid diversion plate 18 disposed on the upper side of the lower mold plate 2. Several injection tubes 19 that vertically penetrate the upper mold plate 1 and are connected to the molding cavity 4 are fixed to the bottom of the injection liquid diversion plate 18. Multi-point injection can be achieved through the injection liquid diversion plate and the several injection tubes to improve the injection efficiency.

[0035] Preferably, the upper insert 17, the front and rear core-pulling inserts 5, and the left and right core-pulling inserts 6 are further provided with a plurality of cooling channels 20. Providing cooling channels in the upper insert 17, the front and rear core-pulling inserts 5, and the left and right core-pulling inserts 6 can improve cooling efficiency.

[0036] The working principle of this utility model is as follows: the linkage drive component 7 can drive the upper template to rise and fall in the vertical direction. When the upper template moves upward, it can drive the front and rear core pulling inserts 5 and the left and right core pulling inserts 6 to move synchronously away from the molding cavity through the outer core pulling drive component. The linkage drive component 7 can move synchronously with the left and right core pulling inserts to realize the linkage between the upper template and the linkage outer insert structure 3, so as to prevent interference between the outer core pulling drive component and the linkage outer insert structure 3 when the mold is closed again.

[0037] The two linear actuators can move the upper template upwards in sync. The upward movement of the upper template can drive the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 to move synchronously away from the molding cavity through the outer core-pulling drive assembly. The movement of the left and right core-pulling inserts 6 can drive the linear actuators 8, which are connected to the upper template 1 through the sliding push-pull structure, to move outwards. When the left and right core-pulling inserts 6 move, they can drive the linear actuators 8 to move through the actuator mounting base 9. When the linear actuators move, the T-shaped slider can move in the push-pull groove to maintain the connection between the linear actuators and the connecting base.

[0038] By setting a linkage rod, the front and rear core-pulling blocks 5 and the left and right core-pulling blocks 6 can move synchronously and maintain the connection between the front and rear core-pulling blocks 5 and the left and right core-pulling blocks 6. One end of the linkage rod is connected to the left and right core-pulling blocks by bolts, and the other end is movably connected to the front and rear core-pulling blocks. This can maintain the connection between the front and rear core-pulling blocks 5 and the left and right core-pulling blocks 6 and prevent the linkage rod from falling off.

[0039] When the upper mold plate moves upward, it can drive the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 to move away from the molding cavity through the drive rod to achieve core pulling. The detachable upper insert can reduce the replacement cost when the mold is damaged. The injection liquid diversion plate and several injection tubes can realize multi-point injection to improve injection efficiency. The cooling channel is set in the upper insert 17, the front and rear core-pulling inserts 5 and the left and right core-pulling inserts 6 to improve cooling efficiency.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0041] Although this article frequently uses terms such as upper template 1, lower template 2, linked outer insert structure 3, molding cavity 4, front and rear core-pulling inserts 5, left and right core-pulling inserts 6, linked drive assembly 7, linear driver 8, driver mounting base 9, connecting base 10, push-pull slide 11, T-shaped slider 12, linkage rod 13, linkage rod mounting slide 14, drive rod 15, drive rod slide 16, upper insert 17, injection liquid distribution plate 18, injection pipe 19, cooling channel 20, etc., these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
