Description

Technical Field

[0001] The invention relates to the technical field of mold clamping machines, in particular to a turnover mechanism for a two-platen horizontal mold clamping machine. Background Art

[0002] The mold clamping machine is a specialized mold assembly and testing device, primarily used to pressurize and close the upper and lower molds during the later stages of mold production. It utilizes a variety of reliable devices, including a movable worktable mold clamping and positioning device, an upper movable flip lock, a mechanical flip mechanism, a hydraulic ejector, mold slide control, and a safety device to prevent dropouts. The mold clamping unit comprises a mold clamping mechanism and a hydraulic control system. The clamping mechanism opens and closes the mold, ensuring reliable closing. The hydraulic control system maintains the predetermined pressure, speed, temperature, time, and motion sequence.

[0003] For example, the Chinese invention patent application (application number: 202011360106.4) that has been in the public state discloses an improved vertical injection molding machine clamping mechanism, including an upper movable platen, a lower fixed platen, a lower base plate and a column. The lower fixed platen is located between the upper movable platen and the lower base plate. The column passes through the lower fixed platen, and its upper and lower ends are fixedly connected to the upper movable platen and the lower base plate respectively. The column is movably arranged up and down. There are more than two boosting chambers in the lower fixed platen, and each boosting chamber is installed with a boosting component, and each boosting component is driven and connected to the lower base plate. The injection molding machine clamping mechanism of the present invention adopts a top-down clamping method. When closing the mold, the lower fixed platen is fixed, and the upper movable platen realizes a rapid opening / closing action through two rapid clamping oil cylinders. The lower fixed platen is also a boosting cylinder. The double-plunger boosting method makes the boosting process smoother and the force more uniform. The upper movable platen can be installed with one or two independent injection systems at the same time to realize injection molding of single-color / single-material or two-color / dual-material products.

[0004] However, when the mold to be clamped is high, this vertical clamping machine requires the operator to climb up to complete the mold installation when installing the upper mold of the mold onto the upper movable platen. This operation method is relatively complicated and will bring certain safety hazards to the operator. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a turnover mechanism for a two-platen horizontal mold clamping machine in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a turning mechanism for a two-platen horizontal mold clamping machine is proposed, comprising: a frame;

[0007] A first support plate and a second support plate are symmetrically arranged and rotatable on the frame, the first support plate and the second support plate are both used to fix the mold to be clamped, and the first support plate and the second support plate are both switchable between a first position placed horizontally on the frame and a second position placed vertically on the frame;

[0008] A driving member is fixed on the frame, and is used to drive the first support plate and the second support plate to switch between the first position and the second position.

[0009] In the above-mentioned turning mechanism for a two-plate horizontal mold clamping machine, slideways are provided on both sides of the frame, and sliders are provided on both sides of the first support plate and the second support plate, and the sliders are slidably arranged in the slideways.

The first bearing is movably installed in the mounting groove and the width of the mounting groove is greater than the outer diameter of the first bearing.

[0011] In the above-mentioned flipping mechanism for a two-plate horizontal mold clamping machine, the driving member includes two pushing cylinders arranged on the frame, and the output ends of the two pushing cylinders are respectively connected to the opposite ends of the first support plate and the second support plate.

[0012] In the above-mentioned flipping mechanism for a two-plate horizontal mold clamping machine, a second bearing is provided at the opposite end of the first support plate and the second support plate, and a roller is provided on the outer wall of the second bearing, and the roller is rotatably arranged on the frame.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 6 As shown, the present invention is a flip mechanism for a two-plate horizontal clamping machine, comprising: a frame 1; a first support plate 2 and a second support plate 3 symmetrically arranged and capable of rotating on the frame 1, the first support plate 2 and the second support plate 3 are both used to fix the mold to be clamped, and the first support plate 2 and the second support plate 3 are both capable of switching between a first position horizontally placed on the frame 1 and a second position vertically placed on the frame 1; a driving member, which is fixed on the frame 1, and the driving member is used to drive the first support plate 2 and the second support plate 3 to switch between the first position and the second position.

[0026] Based on the above embodiments, the technical problem to be solved by the present application is how to solve the problem of difficulty in disassembling and assembling the mold of the vertical mold clamping machine in the prior art. To this end, the present application provides a first support plate 2 and a second support plate 3 that are rotatably mounted on a frame 1. Both the first support plate 2 and the second support plate 3 are used to secure the mold to be clamped, and both the first support plate 2 and the second support plate 3 can be switched between a first position placed horizontally on the frame 1 and a second position placed vertically on the frame 1. During operation, the first support plate 2 and the second support plate 3 are first rotated to the first position on the frame 1 so that both the first support plate 2 and the second support plate 3 are placed horizontally on the frame 1. At this time, one end of the mold in the clamped state can be secured to the first support plate 2 or the second support plate 3. After the mold is placed, both the first support plate 2 and the second support plate 3 are rotated to the second position in a vertical state, and then the other end of the mold is secured to the second support plate 3 or the first support plate 2. Since the mold is in a horizontal state when the other end is locked, the operator does not need to climb high to secure the other end of the mold, as is the case with the mold installation method of a vertical extruder, and the mold assembly and disassembly method is simpler and more convenient. In this way, the problem of difficult assembly and disassembly of molds in vertical clamping machines in the prior art is solved.

[0027] Furthermore, slideways 4 are provided on both sides of the frame 1 , and sliders 5 are provided on both sides of the first support plate 2 and the second support plate 3 , and the sliders 5 are slidably arranged in the slideways 4 .

[0028] Based on the above embodiments, the technical problem to be solved by the present application is how to facilitate the rotation of the first support plate 2 and the second support plate 3 on the rack 1. To this end, the present application provides slideways 4 on both sides of the rack 1, and sliders 5 on both sides of the first support plate 2 and the second support plate 3. The sliders 5 are slidably arranged in the slideways 4. When the first support plate 2 and the second support plate 3 are in the first position, the sliders 5 slide in the slideways 4, thereby driving the first support plate 2 and the second support plate 3 to rotate from the first position to the second position. This facilitates the rotation of the first support plate 2 and the second support plate 3 on the rack 1.

[0029] Furthermore, a rotating shaft 6 is provided on both sides of the first support plate 2 and the second support plate 3, a first bearing 7 is sleeved on the outer side of the rotating shaft 6, a mounting groove 8 is provided in the slider 5, the first bearing 7 is movably installed in the mounting groove 8 and the width of the mounting groove 8 is greater than the outer diameter of the first bearing 7.

[0030] Based on the above embodiments, the technical problem to be solved by the present application is how to prevent the first support plate 2 and the second support plate 3 from getting stuck when switching from the first position to the second position, and how to improve the service life of the first bearing 7. To this end, the present application is provided with a rotating shaft 6 on both sides of the first support plate 2 and the second support plate 3, and a first bearing 7 is sleeved on the outer side of the rotating shaft 6. A mounting groove 8 is provided in the slider 5, and the first bearing 7 is movably installed in the mounting groove 8, and the width of the mounting groove 8 is greater than the outer diameter of the first bearing 7. During the process of switching the first support plate 2 and the second support plate 3 from the first position to the second position, the slider 5 slides in the sliding groove. Since the slider 5 is connected to the first support plate 2 and the second support plate 3 through bearings, and the width of the mounting groove 8 is greater than the outer diameter of the first bearing 7, At the moment when the first support plate 2 and the second support plate 3 switch from the first position to the second position, the first bearing 7 can rotate and move within the mounting groove 8, thereby preventing the slider 5 from being unable to move due to being in a dead point position. In addition, during the mold closing process, since the width of the mounting groove 8 is greater than the outer diameter of the first bearing 7, after the first support plate 2 and the second support plate 3 switch from the first position to the second position and the first support plate 2 and the second support plate 3 are fixed to the frame 1, the gravity of the first support plate 2 and the second support plate 3 will not act on the first bearing 7. In this way, the first support plate 2 and the second support plate 3 can be prevented from getting stuck when switching from the first position to the second position, and the service life of the first bearing 7 can be improved. Preferably, the mounting groove 8 is a runway type.

[0031] Furthermore, the driving member includes two pushing cylinders 9 arranged on the frame 1, and the output ends of the two pushing cylinders 9 are respectively connected to the opposite ends of the first support plate 2 and the second support plate 3.

[0032] Based on the above embodiments, the problem to be solved by the present application is how the driving member realizes the switching of the positions of the first support plate 2 and the second support plate 3 on the frame 1. To this end, the present application sets two pushing cylinders 9 on the frame 1 as driving members, and the output ends of the two pushing cylinders 9 are respectively connected to the opposite ends of the first support plate 2 and the second support plate 3. During operation, the two pushing cylinders 9 respectively push the opposite ends of the first support plate 2 and the second support plate 3 so that the sliders 5 set at the other ends of the first support plate 2 and the second support plate 3 slide in the slideway 4, thereby realizing the rotation of the first support plate 2 and the second support plate 3 on the frame 1. In this way, the switching of the positions of the first support plate 2 and the second support plate 3 on the frame 1 is realized.

[0033] Furthermore, a second bearing 10 is provided at one end opposite to the first support plate 2 and the second support plate 3 , and a roller 11 is sleeved on the outer wall of the second bearing 10 , and the roller 11 is rotatably arranged on the frame 1 .

[0034] Based on the above-described embodiments, the technical problem to be solved by this application is how to reduce the friction between the first support plate 2 and the second support plate 3 and the frame 1 when the first support plate 2 and the second support plate 3 switch positions. To this end, this application provides second bearings 10 at opposing ends of the first support plate 2 and the second support plate 3, and sleeves rollers 11 on the outer sidewalls of the second bearings 10. When the first support plate 2 and the second support plate 3 rotate, the opposing ends of the first support plate 2 and the second support plate 3 are in rolling connection with the frame 1 via the rollers 11. This reduces the friction between the first support plate 2 and the second support plate 3 and the frame 1.

[0035] Furthermore, the driving component also includes a lifting cylinder 12 fixed on the frame 1, and a chain plate 13 is rotatably provided on the frame 1. The lifting cylinder 12 and the slider 5 are connected by a chain 14, and the chain 14 is engaged with the chain plate 13.

[0036] Based on the above embodiment, the technical problem to be solved by the present application is how to make the pushing cylinder 9 more easily drive the first support plate 2 and the second support plate 3 to rotate on the frame 1. To this end, the present application sets a lifting cylinder 12 and a chain plate 13 on the frame 1. The lifting cylinder 12 is connected to the slider 5 by a chain 14, and the chain 14 is engaged with the chain plate 13. When the pushing cylinder 9 drives the opposite ends of the first support plate 2 and the second support plate 3 to rotate, the lifting cylinder 12 drives the other ends of the first support plate 2 and the second support plate 3 to slide in the slide 4 through the chain 14. In this way, the pushing cylinder 9 can more easily drive the first support plate 2 and the second support plate 3 to rotate on the frame 1.
