Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a quick mold change device for injection molding machines. Background Technology

[0002] Injection molding machines (IMMs) are core equipment in the plastics processing industry. They are primarily used to inject molten plastic into a closed mold cavity under high pressure, which then cools and solidifies to form plastic products of specific shapes and sizes. Their design, manufacturing precision, and maintenance directly impact product quality and production efficiency. Widely used in industries such as automotive, electronics, medical, and packaging, molds are often referred to as the "mother of industry." Their design must comprehensively consider plastic shrinkage, product structural precision, and production efficiency, directly affecting cost control and product quality. With the development of intelligent manufacturing, mold design is trending towards digitalization to meet the production needs of complex products.

[0003] A mold changing structure for an injection molding machine is disclosed in utility model application number 202323388538.8. This structure includes a positioning component and a limiting component. The positioning component comprises a pair of symmetrically arranged positioning protrusions on the left and right sides, and a control module that can control the positioning protrusions to move synchronously towards or away from each other. Furthermore, the bottom of the mold also has a pair of symmetrically arranged positioning grooves on the left and right sides. Therefore, the control module can align the positioning protrusions with the positioning grooves on any size mold, allowing the positioning protrusions to be inserted into the positioning grooves, thereby positioning the mold on the worktable for rapid positioning. The limiting component is movable on the worktable, allowing its position to be adjusted according to the specific size of the mold before limiting, making it flexible and convenient to use.

[0004] However, in the mold changing structure of the above-mentioned injection molding machine, the mold still needs to be hoisted after the limiting component is disassembled before the mold can be changed, which can easily affect the mold changing efficiency. In the above-mentioned mold changing structure of injection molding machine, the mold and the worktable are only positioned by the cooperation of the positioning protrusion and the positioning groove, which makes the stability of the mold low. Therefore, this utility model proposes a quick mold changing device for injection molding machine to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a quick mold change device for injection molding machines. This quick mold change device for injection molding machines uses a first electric telescopic rod to push the upper mold seat down to close the mold, and then a second electric telescopic rod to push the change push plate to move, thereby moving the mold body for replacement. This solves the problem of needing to hoist the mold to change it, effectively improving the mold change efficiency. The motor drives the rotating shaft to rotate, which in turn drives the locking block to rotate synchronously and engage in the locking slot to lock and limit the mold body, effectively improving the clamping stability of the mold.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: A quick mold change device for an injection molding machine, including a worktable, a support, a mold sliding change mechanism, a moving mechanism, and a rotation locking mechanism.

An extension frame is fixedly provided in the middle of one side of the support. The first electric telescopic rod is symmetrically fixedly provided above the support. The upper mold seat is fixedly provided at the telescopic end of the first electric telescopic rod. The lower mold seat is fixedly provided in the middle of the worktable. The upper mold seat and the lower mold seat are equipped with a change slide rail at their inner bottoms. The second electric telescopic rod is fixedly provided in one side of the extension frame. The change push plate is fixedly provided at the telescopic end of the second electric telescopic rod. A mold body is slidably provided between the upper mold seat and the lower mold seat. Moving transport mechanisms are symmetrically provided on both sides of the worktable. Rotation locking mechanisms are symmetrically provided front and rear of the upper mold seat and the lower mold seat.

[0007] A further improvement is that the upper mold base and the lower mold base are positioned vertically in correspondence.

[0008] Further improvements are made in that: the mobile transportation mechanism includes a mobile platform, a support base, a support slide rail, a docking guide rail, a docking groove, and casters. The mobile platform is provided close to both sides of the worktable, and the support base is fixedly provided on the mobile platform. The support slide rail is fixedly provided on the support base. The docking guide rail is fixedly provided symmetrically on both sides of the mobile platform. The docking groove is symmetrically provided on both sides of the mobile platform. Casters are fixedly provided at the four corners of the bottom of the mobile platform.

[0009] Further improvements include: the support slide rail and the replacement slide rail are spliced ​​and fitted at both ends, and the docking guide rail and the docking groove slide together.

[0010] A further improvement is that the rotation locking mechanism includes a motor, a rotating shaft, locking blocks, and locking slots. The upper mold base and the lower mold base are symmetrically fixed with motors. The output end of the motor drives the rotating shaft. Locking blocks are arranged and fixed on the rotating shaft. Locking slots are symmetrically arranged on the mold body.

[0011] A further improvement is that the rotating shaft is located on the front and rear sides of the upper mold base and the lower mold base.

[0012] A further improvement is that the locking block rotates and inserts into the locking slot to engage and lock.

[0013] The beneficial effects of this utility model are as follows: This utility model uses the first electric telescopic rod to push the upper mold seat down to close the mold, and then the second electric telescopic rod to push the replacement push plate to move, thereby moving the mold body for replacement. This solves the problem of needing to hoist the mold to replace it, effectively improving the mold replacement efficiency. The motor drives the rotating shaft to rotate, which drives the locking block to rotate synchronously and lock into the locking slot to lock and limit the mold body, effectively improving the clamping stability of the mold.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a quick mold change device for an injection molding machine, including a worktable 1, a support 2, a mold sliding change mechanism, a moving mechanism, and a rotation locking mechanism. The support 2 is fixedly mounted in the middle of the worktable 1. The mold sliding change mechanism includes an extension frame 3, a first electric telescopic rod 4, an upper mold base 5, a lower mold base 6, a change slide rail 7, a second electric telescopic rod 8, and a change push plate 9. The extension frame 3 is fixedly mounted in the middle of one side of the support 2. The first electric telescopic rod 4 is symmetrically fixedly mounted above the support 2. The upper mold base 5 is fixedly mounted at the telescopic end of the first electric telescopic rod 4. The lower mold base 6 is fixedly mounted in the middle of the worktable 1. The change slide rail 7 is provided at the bottom of the inner sides of the upper mold base 5 and the lower mold base 6. The second electric telescopic rod 8 is fixedly mounted on one side of the extension frame 3. The telescopic end of the telescopic rod 8 is fixedly equipped with a replacement push plate 9. The upper mold seat 5 and the lower mold seat 6 are fitted together with a mold body 10. The upper mold seat 5 and the lower mold seat 6 are vertically aligned. When the mold body 10 needs to be replaced, the first electric telescopic rod 4 extends to drive the upper mold seat 5 to descend and drive the mold body 10 to close. Then, the second electric telescopic rod 8 extends to drive the replacement push plate 9 to extend and push the mold to be replaced to slide along the replacement slide rail 7 between the upper mold seat 5 and the lower mold seat 6, thus pushing out the original mold body 10 to achieve quick replacement. The mold replacement by sliding solves the problem of hoisting when replacing the mold and effectively improves the replacement efficiency. The worktable 1 is symmetrically equipped with a moving transport mechanism on both sides, and the upper mold seat 5 and the lower mold seat 6 are symmetrically equipped with a rotating locking mechanism at the front and rear.

[0021] The mobile transport mechanism includes a mobile platform 11, a support base 12, a support slide rail 13, a docking guide rail 14, a docking groove 15, and casters 16. The mobile platform 11 is mounted close to both sides of the workbench 1. The support base 12 is fixedly mounted on the mobile platform 11, and the support slide rail 13 is fixedly mounted on the support base 12. The docking guide rail 14 is symmetrically fixed on both sides of the mobile platform 11, and the docking groove 15 is symmetrically opened on both sides of the mobile platform 11. Casters 16 are fixedly mounted at the four corners of the bottom of the mobile platform 11. The support slide rail 13 and the replacement slide rail 7 are spliced ​​and fitted at both ends. The docking guide rail 14 and the docking groove 15 cooperate to slide. When replacing the mold, one set of mobile platforms 11 with the mold to be replaced is first pushed to one side of the workbench 1 and slides along the docking guide rail 14 to fit the docking groove 15. Then, the other set of mobile platforms 11 and the docking guide rail 14 are pushed to the other side of the workbench 1. This makes it convenient to push the mobile platform 11 to move the mold body 10 after the mold replacement is completed, solving the problem of needing to lift the mold to replace it.

[0022] The rotation locking mechanism includes a motor 17, a rotating shaft 18, locking blocks 19, and locking slots 20. The upper mold base 5 and the lower mold base 6 are symmetrically fixed with the motor 17. The output end of the motor 17 drives the rotating shaft 18. The locking blocks 19 are arranged and fixed on the rotating shaft 18. The mold body 10 is symmetrically arranged with locking slots 20. The rotating shaft 18 is located on the front and rear sides of the upper mold base 5 and the lower mold base 6. The locking blocks 19 rotate and insert into the locking slots 20 to lock. When locking and limiting are required after mold replacement, the motor 17 drives the rotating shaft 18 to rotate, which in turn drives the locking blocks 19 to rotate and insert into the locking slots 20 at the front and rear of the mold body 10, so that the mold body 10 is locked with the upper mold base 5 and the lower mold base 6 to form a whole, effectively improving the stability of the mold.

[0023] In this quick mold change device for injection molding machines, when the mold body needs to be replaced, the first electric telescopic rod extends, driving the upper mold seat to descend and close the mold body. Then, the second electric telescopic rod extends, driving the replacement push plate to slide the mold to be replaced along the replacement slide rail between the upper and lower mold seats, thereby pushing out the original mold body. This achieves quick mold replacement, avoiding hoisting operations and improving replacement efficiency. A mobile transport mechanism assists in mold replacement and transfer. Before replacing the mold, a set of moving platforms holding the mold to be replaced slides along the docking guide rail and docking groove to one side of the worktable, and then another set of moving platforms is pushed to the other side of the worktable. After replacement, the moving platforms can be pushed, using the casters to move the mold body, solving the problem of hoisting and transferring molds during replacement. After mold replacement, the motor drives the rotating shaft to rotate, causing the locking blocks arranged on the shaft to rotate and insert into the symmetrically opened locking slots on the front and back of the mold body, locking the mold body to the upper and lower mold seats as a whole, effectively improving the stability of the mold during use.
