Description

Technical Field

[0001] This utility model belongs to the field of mold flipping machines, and specifically relates to a rotary mold flipping machine. Background Technology

[0002] In mold making, plastic molding, metal forming, and metal processing industries, 90-degree flipping machines are commonly used auxiliary equipment, primarily for flipping workpieces 90 degrees vertically. In automated production lines, in addition to flipping workpieces 90 degrees vertically, it is often required that they be further rotated 90 or 180 degrees horizontally for subsequent processing or assembly. However, currently these operations are typically performed on two separate machines: one for vertical flipping and the other for horizontal rotation.

[0003] This separate design not only occupies more installation space, but also incurs additional time and manpower costs due to the need to move workpieces between the two machines, reducing overall production efficiency. Furthermore, the connection between different machines may introduce errors, affecting the consistency of the final product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rotary mold flipping machine in view of the current situation of the prior art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rotary mold flipping machine is proposed, including: a support base, which has a length direction, a width direction and a height direction;

[0006] A rotating seat is rotatably connected to the support seat via a rotating mechanism, and the rotation center axis of the rotating seat is parallel to the height direction of the support seat;

[0007] A turntable includes an arc-shaped main body, and a first support plate and a second support plate intersecting and arranged on the arc-shaped main body. The first support plate and the second support plate are arranged perpendicularly. The turntable is rotatably arranged on the rotating seat, and the rotation center axis of the turntable is parallel to the width direction of the support seat.

[0008] A limiting mechanism is disposed between the rotating seat and the support seat to limit the rotation of the rotating seat.

[0009] In the aforementioned rotary mold-changing machine, the rotary mechanism is a gear transmission mechanism. A worm wheel is fixedly installed on the support base. The rotation center axis of the rotating base coincides with the axis of the worm wheel. A worm is installed on the rotating base that meshes with the worm wheel. When the worm rotates, it drives the rotating base to rotate.

[0010] In the aforementioned rotary mold-turning machine, the rotary mechanism is a direct-drive motor mechanism. A first motor is fixedly mounted on the support base, and a speed reducer is mounted at the output end of the first motor. The output end of the speed reducer is connected to the rotating base.

[0011] In the aforementioned rotary mold-turning machine, the limiting mechanism is a mechanical limiting mechanism, a clamping block is provided on the rotating seat, and a limiting stop is provided on the support seat, with the clamping block and the limiting stop moving against each other.

[0012] In the aforementioned rotary mold-turning machine, the limiting mechanism is a photoelectric limiting mechanism. A first limiting block is provided on the rotating seat, and a photoelectric sensor is provided on the support seat. The photoelectric sensor is electrically connected to the first motor, and when the photoelectric sensor detects the first limiting block, it is used to control the first motor to stop working.

[0013] In the aforementioned rotary mold-turning machine, a chain is laid on the end face of the arc-shaped main body away from the first support plate, and a driven wheel is provided on the rotating seat. The driven wheel and the chain form a transmission mechanism for driving the turntable to rotate relative to the rotating seat.

[0014] In the aforementioned rotary mold-turning machine, a second motor is provided on the rotating base, and a drive wheel is provided at the output end of the second motor. The drive wheel meshes with the driven wheel to provide a power source for the rotation of the driven wheel.

[0015] In the aforementioned rotary mold-turning machine, the turntable is provided with reinforcing ribs on both sides along the width direction of the support base. The reinforcing ribs connect the arc-shaped main body and the first support plate, as well as the arc-shaped main body and the second support plate.

[0016] In the aforementioned rotary mold-turning machine, rollers are provided on both sides of the rotating base along the width direction of the support base, and the rollers movably abut against the turntable.

[0017] In the aforementioned rotary mold-changing machine, the rollers include:

[0018] A rotating shaft is connected to the rotating seat, and the rotating shaft is threadedly connected to the rotating seat;

[0019] A bearing, which is fitted onto the rotating shaft;

[0020] A rotating sleeve is fitted onto the outer ring of the bearing and is interference-fitted thereto.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) By setting up a support base with length, width and height directions, and setting a rotatable rotating base and turntable structure on it, the workpiece can be flexibly flipped in different spatial directions. This structure breaks the limitation of traditional mold flipping equipment that can only flip in one direction, and realizes the completion of multiple angle flipping tasks on the same equipment, effectively reducing the number of equipment and installation space required for the production line, and improving the degree of equipment integration and production efficiency; at the same time, the overall structure is compact and stable, improving the operational safety and applicability, and is especially suitable for the automated processing needs of complex molds.

[0023] (2) Using a worm gear transmission mechanism as the rotary drive method not only results in a compact structure and smooth transmission, but also has excellent self-locking performance, ensuring that the rotating seat can remain stably stationary at any angle and avoiding malfunctions caused by gravity or external forces. Compared with existing hydraulic or pneumatic systems, worm gear transmission has a fast response and high control precision, making it particularly suitable for occasions requiring frequent starts and stops and precise positioning, which helps to improve the reliability of equipment operation and the safety of work.

[0024] (3) The rotation of the rotating seat is achieved through a direct-drive reduction mechanism of the motor, which simplifies the transmission link and improves the system response speed and control accuracy. This drive method is easy to connect to the PLC control system to realize remote control and automated operation, which is in line with the development trend of modern intelligent manufacturing. At the same time, reducing intermediate transmission components also helps to reduce maintenance frequency and improve equipment operating efficiency and service life. Attached Figure Description

Detailed Implementation

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figures 1 to 4 As shown, the present invention provides a rotary mold-turning machine, comprising: a support base 100, a rotating base 200, a turntable 300, a limiting mechanism 400, and a rotating mechanism 500.

[0033] Specifically, the support base 100 has a length direction L, a width direction W, and a height direction H; the rotating base 200 is rotatably connected to the support base 100 via a rotating mechanism 500, and the rotation center axis of the rotating base 200 is parallel to the height direction H of the support base 100; the turntable 300 includes an arc-shaped body 310, and a first support plate 320 and a second support plate 330 intersectingly arranged on the arc-shaped body 310, the first support plate 320 and the second support plate 330 being arranged perpendicularly, the turntable 300 being rotatably mounted on the rotating base 200, and the rotation center axis of the turntable 300 being parallel to the width direction W of the support base 100; the limiting mechanism 400 is disposed between the rotating base 200 and the support base 100, and is used to limit the rotation of the rotating base 200.

[0034] In this design, the rotation angle of the turntable 300 is preferably 90°, and the rotation angle of the rotating base 200 is preferably 180°. The 180° rotation of the rotating base 200 is used to move the workpiece or mold after the turntable 300 receives it; the 90° rotation of the turntable 300 is used to rotate the workpiece. The arc-shaped main body 310 structure provided on the turntable 300 facilitates the 90° rotation of the turntable 300. In a preferred embodiment, the central angle corresponding to the arc-shaped main body 310 is 90°.

[0035] The limiting mechanism 400 is used to stop the rotation of the rotating seat 200 after it has rotated to a predetermined angle (e.g., 180°), thereby improving the accuracy and consistency of the rotation angle of the rotating seat 200.

[0036] By setting up a support base 100 with length, width, and height directions H, and mounting a rotatable rotating base 200 and a turntable 300 on it, the workpiece can be flexibly flipped in different spatial directions. This structure breaks the limitation of traditional mold-flipping equipment that can only achieve single-direction flipping, realizing the function of flipping at multiple angles on the same equipment. It effectively reduces the number of equipment and installation space required for the production line, and improves the integration level and production efficiency of the equipment. At the same time, the overall structure is compact and stable in operation, improving the safety and applicability of operation, and is especially suitable for the automated processing needs of complex molds.

[0037] In one embodiment, the rotating mechanism 500 is a gear transmission mechanism. A worm wheel is fixedly installed on the support base 100. The rotation center axis of the rotating base 200 coincides with the axis of the worm wheel. A worm is installed on the rotating base 200 that meshes with the worm wheel. When the worm rotates, it drives the rotating base 200 to rotate.

[0038] Employing a worm gear transmission mechanism as the rotary drive method not only results in a compact structure and smooth transmission but also possesses excellent self-locking performance, ensuring that the rotating seat 200 remains stably stationary at any angle and preventing malfunctions caused by gravity or external forces. Compared to existing hydraulic or pneumatic systems, worm gear transmission offers fast response and high control precision, making it particularly suitable for applications requiring frequent starts and stops and precise positioning. This contributes to improving the reliability of equipment operation and the safety of work. Preferably, the rotation of the worm is driven by a combination of a motor and a reducer.

[0039] In another embodiment, the rotating mechanism 500 is a direct-drive motor mechanism. A first motor is fixedly mounted on the support base 100, and a reducer is mounted on the output end of the first motor. The output end of the reducer is connected to the rotating base 200.

[0040] The 200° rotation of the rotating base is achieved through a direct-drive reduction mechanism using a motor, simplifying the transmission chain and improving system response speed and control accuracy. This drive method facilitates integration with a PLC control system, enabling remote control and automated operation, aligning with the development trend of modern intelligent manufacturing. Furthermore, reducing intermediate transmission components helps lower maintenance frequency, improving equipment operating efficiency and lifespan.

[0041] In one embodiment, the limiting mechanism 400 is a mechanical limiting mechanism 400, the rotating seat 200 is provided with a pressing block, and the support seat 100 is provided with a limiting stop, and the pressing block and the limiting stop are movably abutted against each other.

[0042] The introduction of the mechanical limit structure provides reliable physical limit protection for the rotation of the rotating seat 200, preventing overtravel risks caused by control system failure or misoperation, and enhancing the safety and stability of equipment operation. Especially in automated production lines, mechanical limit, as one of the multiple safety protection mechanisms, helps to improve the fault tolerance of the entire equipment and ensure the safety of personnel and equipment.

[0043] In another embodiment, the limiting mechanism 400 is a photoelectric limiting mechanism 400. A first limiting block is provided on the rotating seat 200, and a photoelectric sensor is provided on the support seat 100. The photoelectric sensor is connected to the first motor by an electrical signal, and when the photoelectric sensor detects the first limiting block, it is used to control the first motor to stop working.

[0044] The photoelectric limit mechanism 400, as a non-contact detection method, boasts fast response and high sensitivity, triggering a stop signal at precise locations to achieve high-precision positioning for corner control. Compared to existing mechanical limiters, it is wear-free and has a long lifespan, making it particularly suitable for high-frequency, high-speed flipping operations. Furthermore, this limiter method is easily integrated with motor control systems to achieve intelligent control, enhancing equipment automation and flexible production capabilities.

[0045] It is worth mentioning that a chain 340 is laid on the end face of the arc-shaped main body 310 away from the first support plate 320, and a driven wheel 350 is provided on the rotating seat 200. The driven wheel 350 and the chain 340 form a transmission mechanism for driving the turntable 300 to rotate relative to the rotating seat 200.

[0046] During operation, the driven wheel 350 engages with the chain 340, driving the chain 340 as it rotates, thus causing the turntable 300 to rotate relative to the rotating base 200. The transmission structure consisting of the chain 340 and the driven wheel 350 provides a stable and efficient power transmission path for the turntable 300 to rotate around the rotating base 200. This structure is simple, has a high load-bearing capacity, and is suitable for continuous operation under complex conditions. Furthermore, this transmission method facilitates disassembly and maintenance, helping to reduce subsequent maintenance costs. Simultaneously, by replacing different sprocket sizes, the speed can be adjusted, further expanding the equipment's application range.

[0047] Preferably, a second motor is provided on the rotating base 200, and a driving wheel is provided at the output end of the second motor. The driving wheel meshes with the driven wheel 350 to provide a power source for the rotation of the driven wheel 350.

[0048] The second motor and drive wheel provide an independent power source for the turntable 300, making its rotation operation more flexible and controllable. Combined with the first rotary axis 211 system, it can achieve synchronous or asynchronous motion in two degrees of freedom, significantly improving the versatility and precision of mold-turning operations, and is especially suitable for adjusting the spatial posture of complex molds.

[0049] In this design, the turntable 300 is provided with reinforcing ribs on both sides along the width direction W of the support base 100. The reinforcing ribs connect the arc-shaped main body 310 and the first support plate 320, as well as the arc-shaped main body 310 and the second support plate 330.

[0050] The reinforced rib design effectively enhances the overall rigidity and bending strength of the turntable 300, maintaining structural stability even under heavy loads and preventing deformation and damage caused by vibration or uneven load. This structural design improves the long-term reliability of the equipment, extends its service life, and is particularly suitable for the tilting operation of heavy molds.

[0051] Preferably, the rotating seat 200 is provided with rollers 210 on both sides along the width direction W of the support seat 100, and the rollers 210 move against the turntable 300.

[0052] The roller 210 structure plays an auxiliary guiding and supporting role during the rotation of the turntable 300, reducing rotational friction resistance and making the turntable 300 run more smoothly. At the same time, the movable contact relationship between the roller 210 and the turntable 300 helps to distribute the load and reduce local stress concentration, thereby improving the dynamic performance and service life of the entire system.

[0053] Furthermore, the roller 210 includes: a rotating shaft 211 connected to the rotating seat 200, with the rotating shaft 211 threadedly connected to the rotating seat 200; a bearing 212 sleeved on the rotating shaft 211; and a rotating sleeve 213 sleeved on the outer ring of the bearing 212 and interference-fitted therewith.

[0054] The roller 210 assembly adopts a combination structure of shaft 211, bearing 212 and rotating sleeve 213, which is easy to assemble, runs stably, and has a low coefficient of rotational friction and high wear resistance. The rotating sleeve 213 and bearing 212 adopt an interference fit to ensure a firm connection and prevent loosening and falling off, further improving the reliability and safety of roller 210 in high-load and high-frequency working environments.
