Abstract

This invention relates to an anti-deformation limiting mechanism for an automatic mold-changing fixture for foamed boxes. The mechanism includes a main body with a first pressure pump mounted on its front outer surface. This pump drives a telescopic rod to extend or retract forward or backward. Simultaneously, the first pressure pump moves the telescopic rod forward, stopping and limiting the position of a first clamp, preventing positional deviation during use and improving the device's accuracy. A connecting rod allows the first and second clamps to move simultaneously in one direction, effectively limiting the mold-changing fixture and improving finished product quality and reducing the defect rate. Furthermore, the cooperation between the first limiting block and the first rotating component further enhances the device's accuracy, restricting the range of motion of the first and second clamps, improving the accuracy of the limiting, and effectively preventing deformation and positional deviation of the finished product.

Description

Technical Field

[0001] This invention relates to the field of automatic foaming film changing fixtures, specifically an anti-deformation limiting mechanism for an automatic foaming mold changing fixture for box bodies. Background Technology

[0002] The mold for foam molding is a plastic foaming mold. Foaming resin is directly filled into the mold and heated to melt, forming a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed. The bubble nuclei grow to form foam plastic parts. There are three common foaming methods: physical foaming, chemical foaming, and mechanical foaming. The mold head has a streamlined flow channel surface, a two-half mold body design, and the mold head is easy to disassemble and clean. The manual fine-tuning elastic mold lip or movable upper mold lip design can be used to adapt to different thickness requirements of the extruded sheet. The vertical or 45° inclined flow bar design can be used to adapt to the uniform distribution of molten material with different viscosities. The mold body is made of high-quality mold steel or imported alloy steel to extend the mold life.

[0003] Currently, existing devices still have shortcomings in the use of anti-deformation mechanisms. Most automatic film changing fixtures will shift in position during film changing, which will cause the finished product to have deviations in position and shape after it comes out, thereby increasing the defect rate, increasing costs, and reducing the quality of finished products.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to limit and fix the film-changing fixture. A first pressure pump drives a telescopic rod to extend or retract forward, improving the convenience and efficiency of the device during operation. Simultaneously, the first pressure pump moves the telescopic rod forward, stopping and limiting the position of the first clamp, preventing positional deviation during use and improving the device's accuracy. Furthermore, a connecting rod drives the first and second clamps to move simultaneously in one direction, effectively limiting the film-changing fixture, thereby improving product quality and reducing the defect rate. The cooperation between the first limiting block and the first rotating component further enhances the device's accuracy, restricting the range of motion of the first and second clamps, improving positioning precision, and effectively preventing product deformation and positional deviation. Therefore, this invention provides an anti-deformation limiting mechanism for an automatic mold-changing fixture for foamed boxes, solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-deformation limiting mechanism for an automatic mold-changing fixture for foamed boxes includes a main body. A first pressure pump is provided on the front outer surface of the main body. A fixing block is fixedly connected to the left outer surface of the first pressure pump. The rear end of the fixing block is fixed to the front outer surface of the main body. A telescopic rod is provided near the middle position on the right outer surface of the first pressure pump. A U-shaped block is fixedly connected to the right outer surface of the telescopic rod. A first clamp is provided on the right outer surface of the U-shaped block.

[0008] Furthermore, a first limiting block is provided on the rear outer surface of the first clamp, and a first rotating member is provided on the front outer surface of the first limiting block near the middle position. The first rotating member passes through the front outer surface of the first clamp and extends to the front outer surface of the first limiting block. The first rotating member is movably connected to the first clamp, and a connecting rod is provided on the front outer surface of the first clamp at the upper end of the first rotating member.

[0009] Furthermore, a second rotating member is inserted through the outer surface of the front end of the connecting rod near the left side, and the second rotating member is inserted through and extended to be fixed to the outer surface of the front end of the first clamp, and the second rotating member is movably connected to the connecting rod. A second clamp is symmetrically arranged on the outer surface of the right side of the connecting rod and the second rotating member.

[0010] Furthermore, a second limiting block is provided on the rear outer surface of the second clamp, and a fourth rotating member is provided on the front outer surface of the second limiting block near the middle position. The fourth rotating member passes through the front outer surface of the second clamp and extends to the rear end to be fixedly connected to the second limiting block.

[0011] Furthermore, a third rotating member is provided on the outer surface of the front end of the second clamp at the upper end of the fourth rotating member. The third rotating member passes through the outer surface of the front end of the connecting rod and extends to the rear end to be fixedly connected to the second clamp. The third rotating member is movably connected to the connecting rod. A clamping plate is provided on the outer surface of the lower end of the second clamp.

[0012] Furthermore, a second pressure pump is fixedly connected to the outer rear surface of the main body near the middle position, and the second pressure pump has the same structure as the first pressure pump.

[0013] Furthermore, the method of using the aforementioned anti-deformation limiting mechanism for an automatic mold-changing fixture for foamed boxes specifically includes the following steps:

[0014] Step 1: First, the telescopic rod is pushed forward by the first pressure pump, so that the U-shaped block pushes the first clamp to one side. Since the first limiting block and the first rotating part limit the first clamp, the first clamp can move on the front outer surface of the first limiting block, preventing the first clamp from shifting and improving the accuracy of the device.

[0015] Step 2: When the first clamp moves in Step 1, it can drive the connecting rod to move. When the connecting rod moves, it can drive the second clamp to move. At the same time, the second clamp can be limited and fixed by the second limiting block to prevent the second clamp from moving and further improve the accuracy of the device.

[0016] Step 3: When the second clamp moves, it drives the lower clamping plate to move as well, which can clamp and fix the film changing clamp and limit its position, thereby effectively preventing the deformation and positional deviation of the finished product during foaming and improving the quality of the finished product.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, by setting a series of structural components such as a first pressure pump, a telescopic rod, a U-shaped block, and a first clamp, the first pressure pump can drive the telescopic rod to move forward or backward during use, thereby improving the convenience of the device during operation and increasing work efficiency. At the same time, by using the first pressure pump to move the telescopic rod forward, it can reach and limit the position of the first clamp, preventing the first clamp from shifting its position during use and improving the accuracy of the device.

[0019] 2. In this invention, by setting a series of structural components such as a first limiting block, a first rotating component, a connecting rod, a second clamp, and a clamping plate, during use, the connecting rod can drive the first clamp and the second clamp to move simultaneously in one direction, thereby effectively limiting the film changing clamp, thereby improving the quality of the finished product and reducing the defect rate. At the same time, by utilizing the cooperation of the first limiting block and the first rotating component, the accuracy of the device can be further improved, limiting the range of motion of the first clamp and the second clamp, improving the accuracy of the limiting, and effectively preventing the deformation of the finished product and the deviation of its position.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-6 As shown, the present invention proposes an anti-deformation limiting mechanism for an automatic mold changing fixture for foaming of a box body, comprising a main body 15. A first pressure pump 1 is provided on the front outer surface of the main body 15. The first pressure pump 1 can push the telescopic rod 3, thereby automatically and accurately limiting the film changing fixture. A fixing block 2 is fixedly connected to the left outer surface of the first pressure pump 1. The rear end of the fixing block 2 is fixed to the front outer surface of the main body 15. A telescopic rod 3 is provided near the middle position on the right outer surface of the first pressure pump 1, which is used to push the first fixture 5, so that the first fixture 5 moves under the push of the telescopic rod 3, thereby adapting to different specifications of film changing fixtures. A U-shaped block 4 is fixedly connected to the right outer surface of the telescopic rod 3. The first fixture 5 is provided on the right outer surface of the U-shaped block 4, which is used to limit and fix the film changing fixture.

[0031] A first limiting block 6 is provided on the outer rear surface of the first clamp 5, which can effectively limit the movement range of the first clamp 5 and improve the accuracy of the device. A first rotating member 7 is provided on the outer front surface of the first limiting block 6 near the middle position. The first rotating member 7 passes through the outer front surface of the first clamp 5 and extends to the outer front surface of the first limiting block 6. The first rotating member 7 is movably connected to the first clamp 5. Through the first rotating member 7, the first clamp 5 can be effectively rotated on the first limiting block 6. A connecting rod 8 is provided on the outer front surface of the first clamp 5 at the upper end of the first rotating member 7. The connecting rod 8 can effectively and synchronously make the first clamp 5 and the second clamp 12 rotate in the same direction at the same time.

[0032] A second pressure pump 14 is fixedly connected to the outer rear surface of the main body 15 near the middle position. The second pressure pump 14 has the same structure as the first pressure pump 1. The second pressure pump 14 with the same structure is used to limit and fix the membrane changing fixture at the rear end position of the main body 15.

[0033] During operation, existing devices cannot effectively limit and fix the components, leading to an increased defect rate and higher costs. This invention addresses this by incorporating a series of structural components, including a first pressure pump 1, a telescopic rod 3, a U-shaped block 4, and a first clamp 5. In use, the first pressure pump 1 drives the telescopic rod 3 to extend or retract forward or backward, improving the ease of operation and work efficiency. Simultaneously, the first pressure pump 1 moves the telescopic rod 3 forward, which in turn reaches and limits the position of the first clamp 5, preventing it from shifting during use and improving the device's accuracy.

[0034] Example 2:

[0035] like Figure 1-6 As shown, a second rotating member 9 passes through the outer surface of the front end of the connecting rod 8 near the left side. The second rotating member 9 facilitates the rotation of the connecting rod 8, thereby effectively driving the first clamp 5 to move. The second rotating member 9 passes through and extends to be fixed to the outer surface of the front end of the first clamp 5, and is movably connected to the connecting rod 8 to facilitate the movement of the connecting rod 8. A second clamp 12 is symmetrically arranged on the outer surface of the right side of the connecting rod 8 and the second rotating member 9. The second clamp 12 can further improve the limiting effect of the device and improve the accuracy.

[0036] The rear outer surface of the second clamp 12 is provided with a second limiting block 11 for limiting the second clamp 12. The front outer surface of the second limiting block 11 is provided with a fourth rotating member 13 near the middle position. The fourth rotating member 13 passes through the front outer surface of the second clamp 12 and extends to the rear end to be fixedly connected to the second limiting block 11, so that the second clamp 12 can move on the second limiting block 11, and at the same time can limit the second clamp 12 to prevent the second clamp 12 from shifting its position when moving.

[0037] The front outer surface of the second clamp 12 is provided with a third rotating member 10 located above the fourth rotating member 13. The third rotating member 10 passes through the front outer surface of the connecting rod 8 and extends to the rear end to be fixedly connected to the second clamp 12, which facilitates the movement of the connecting rod 8. At the same time, the connecting rod 8 can synchronously drive the first clamp 5 and the second clamp 12 to rotate in the same direction. The third rotating member 10 is movably connected to the connecting rod 8. The lower outer surface of the second clamp 12 is provided with a clamping plate 16. The movement of the second clamp 12 drives the clamping plate 16 to move inward or outward, thereby limiting and fixing the membrane changing clamp.

[0038] In operation, existing devices still have shortcomings in the use of anti-deformation mechanisms. Most automatic film-changing jigs experience positional shifts during film changing, leading to deviations in the shape and position of the finished product, thus increasing the defect rate, raising costs, and reducing product quality. This invention addresses these shortcomings by incorporating a series of structural components, including a first limiting block 6, a first rotating component 7, a connecting rod 8, a second clamp 12, and a clamping plate 16. During use, the connecting rod 8 drives the first clamp 5 and the second clamp 12 to move simultaneously in one direction, effectively limiting the film-changing jig and improving product quality while reducing the defect rate. Furthermore, the cooperation between the first limiting block 6 and the first rotating component 7 further enhances the device's accuracy, restricting the range of motion of the first clamp 5 and the second clamp 12, improving the accuracy of the limiting, and effectively preventing deformation and positional deviations of the finished product.

[0039] Working principle of the invention:

[0040] In use, the first pressure pump 1 drives the telescopic rod 3 to extend or retract forward or backward, thereby improving the convenience and efficiency of the device during operation. Simultaneously, the first pressure pump 1 moves the telescopic rod 3 forward, which reaches and limits the position of the first clamp 5, preventing positional deviation during use and improving the device's accuracy. Then, the connecting rod 8 drives the first clamp 5 and the second clamp 12 to move simultaneously in one direction, effectively limiting the film-changing clamps, thus improving the quality of the finished product and reducing the defect rate. Furthermore, the cooperation between the first limiting block 6 and the first rotating component 7 further enhances the device's accuracy, restricting the range of motion of the first clamp 5 and the second clamp 12, improving the accuracy of the limiting, and effectively preventing deformation and positional deviation of the finished product.
