Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold manufacturing and forming, and particularly relates to a whole rotary mold frame. BACKGROUND

[0002] In modern manufacturing industry, reaction foaming forming is an important process widely used in the production of large plastic parts (such as automobile sunroofs, door interior panels, etc.). However, the existing foaming mold frame generally has a significant problem - lack of overall turnover function. This defect leads to many challenges for operators when cleaning the mold and placing the inserts. Specifically, the following aspects are manifested: inconvenient operation: since the mold frame is fixed, the operator needs to frequently bend over, stretch his arms, etc. to access different parts of the mold. Such repetitive movements not only increase the difficulty of operation, but also may cause muscle fatigue and joint injury, affecting the health of the operator. Low efficiency: for large molds, especially those that require delicate operation, the operator may not be able to efficiently complete the cleaning of the upper and lower molds and the placement of the inserts without the aid of additional tools. This not only prolongs the production cycle, but also may cause product quality to decline due to improper operation. Safety risk: without the turnover function, the operator needs to maintain an unhealthy posture for a long time, increasing the incidence of occupational diseases. Increased cost: In order to overcome the above problems, enterprises often need to invest more manpower and resources, such as increasing the number of operators, purchasing auxiliary tools, etc., which undoubtedly increases the production cost. At the same time, due to the inconvenience of operation, the frequency of mold maintenance and maintenance is also increased, further increasing the operating cost of the enterprise.

[0003] In summary, the shortcomings of the existing mold frame seriously restrict the efficiency and safety of the reaction foaming forming process, and a new technical solution is urgently needed to solve these problems. CONTENT OF THE INVENTION

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] The following will be combined with Figure 1 And Figure 10 The technical solutions of the present application are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0045] As Figure 1 The overall rotating die frame structure schematic diagram provided by an embodiment of the present application is shown, as Figure 2 The bottom frame structure schematic diagram of the overall rotating die frame provided by an embodiment of the present application is shown, please refer to Figure 1 And Figure 2 The present application provides an overall rotating die frame, comprising: a bottom frame 1, a rotating support 2, a lower die frame 3 and an upper die frame 4.

[0046] The bottom frame 1 is the basic support structure of the overall rotating die frame, used to bear the weight of the rotating support 2, the lower die frame 3 and the upper die frame 4, and to ensure the stability and reliability of the whole die frame. The bottom frame 1 is usually made of high-strength steel material, with sufficient rigidity and durability, capable of bearing the high pressure and high temperature generated in the reaction foaming forming process.

[0047] The rotating support 2 is rotatably connected with the bottom frame 1 at the support rotation center 22 through the support rotating assembly 21, and the rotating support 2 is driven to rotate around the support rotation center 22 by the support driving member 23, so as to realize large range angle adjustment of the overall die frame. The support driving member 23 can be a motor, a hydraulic motor or other forms of power device, which can ensure the stability and precision of the rotating support 2 at different positions by accurately controlling the rotation angle.

[0048] As Figure 3 The assembly structure schematic diagram of the rotating support, the upper die frame and the lower die frame of the overall rotating die frame in one rotating state provided by an embodiment of the present application is shown, as Figure 4 The overall rotating die frame structure schematic diagram provided by the embodiment in another angle is shown.

[0049] In a specific example, refer to Figure 3 And Figure 4As shown, the support rotating assembly 21 includes a first rotating shaft 211 and a first bearing 212. The first bearing 212 is fixed on the bottom frame 1, and the first rotating shaft 211 is connected to the first bearing 212 at one end and connected to the rotating support 2 at the other end at the rotating support center 22, so that the rotating support 2 can rotate.

[0050] By adjusting a wide range of angles, the rotating support can adapt to different production line layouts, improving production flexibility. For example, when producing different models of automobile parts, the position of the mold can be optimized by adjusting the angle of the rotating support, thereby improving production efficiency and product quality.

[0051] In some embodiments of the present application, referring to Figure 1 and Figure 2 As shown, two support driving members 23 are arranged on both sides of the bottom frame 1, and each support driving member 23 is connected to the rotating support 2 through a support transmission member 24 to drive the rotating support 2 to rotate. By arranging the support driving member 23 on the bottom frame 1, the installation of the driving member can be ensured to be stable, reducing vibration and displacement, and improving the stability of the overall system.

[0052] In some embodiments of the present application, referring to Figure 1 and Figure 2 As shown, the support transmission member 24 includes a drive gear 241 and an arc-shaped rack 242 engaged with the drive gear, and the drive gear 241 is driven by the output shaft of the support driving member 23; the arc-shaped rack 242 is fixedly connected with the rotating support 2.

[0053] The drive gear 241 usually adopts high-precision gears such as helical gears or herringbone gears to ensure low noise and high precision during transmission. The design of the arc-shaped rack 242 ensures that the rotating support 2 always maintains engagement with the drive gear 241 during rotation, ensuring the continuity and stability of transmission.

[0054] In some embodiments of the present application, referring to Figures 1 to 3 As shown, the arc-shaped rack 242 is provided with a limiting member 2421 for limiting the movement range of the arc-shaped rack 242 to prevent excessive rotation. The limiting member 2421 can be a mechanical stop block, a limit switch or other forms of physical obstacles for limiting the movement range of the arc-shaped rack 242. The limiting member 2421 improves the safety of the system, prevents excessive rotation due to improper operation or control system failure, limits the movement range of the arc-shaped rack 242 to ensure stable operation of the rotating support 2 within the predetermined working range, and improves the reliability and service life of the system.

[0055] The lower mold frame 3 is rotationally connected with the rotating support 2 at the lower mold frame rotation center 32 through a lower mold frame rotation assembly 31. A lower mold frame driving member 33 drives the lower mold frame 3 to rotate around the lower mold frame rotation center 32, so as to adjust the angle of the lower half of the mold. The lower mold frame driving member 33 can be an electric motor, a hydraulic motor or other forms of power device, and the stability and precision of the lower mold frame in different positions are ensured by precisely controlling the rotation angle.

[0056] As shown in Figure 5 , it is a lower mold frame structure schematic diagram of the overall mold frame provided by an embodiment of the present application.

[0057] In a specific example, as shown in Figure 3 and Figure 5 , the lower mold frame rotation assembly 31 includes a second rotation shaft (not shown in the figure) and a second bearing member 312. The second bearing member 312 is fixed on the rotating support 2 to reduce friction during rotation. One end of the second rotation shaft is connected with the second bearing 312, and the other end is connected with the lower mold frame 3 at the lower mold frame rotation center 32, so that the lower mold frame 3 can rotate.

[0058] By adjusting the angle of the lower mold frame 3, the complex mold structure can be better adapted. In addition, the independent rotation function of the lower mold frame 3 also facilitates the cleaning and maintenance of the mold.

[0059] In some embodiments of the present application, as shown in Figure 3 and Figure 5 , two lower mold frame driving members 33 are arranged on both sides of the rotating support 2, and each lower mold frame driving member 33 is connected with the lower mold frame 3 through a lower mold frame transmission member 34 to drive the lower mold frame 3 to rotate.

[0060] The connection point of the lower mold frame driving member 33 and the lower mold frame 3 through the lower mold frame transmission member 34 should be a certain distance from the lower mold frame rotation center 32, so that the driving force at the connection point can drive the lower mold frame 3 to rotate around the lower mold frame rotation center 32.

[0061] The lower mold frame driving member 33 can be an electric motor, a hydraulic motor or a pneumatic motor, and the specific choice depends on the load and precision requirements of the application site. For example, in applications requiring high torque and low speed, a hydraulic motor can be selected; while in applications requiring high precision and fast response, a servo motor can be selected.

[0062] By arranging the lower mold frame driving member 33 on the rotating support 2, space can be saved, and the entire device can be more compact. This installation method allows the lower mold frame driving member 33 to rotate with the rotating support 2, adapt to different working positions, and improve flexibility.

[0063] In some embodiments of the present application, as shown in Figure 3 andFigure 5 As shown, the lower mold base transmission member 34 includes a first crank 341 and a first connecting rod 342. One end of the first crank 341 is connected to the lower mold base driving member 33. One end of the first connecting rod 342 is connected to the other end of the first crank 341, and the other end of the first connecting rod 342 is connected to the lower mold base 3.

[0064] The main function of the first crank 341 is to convert the rotary motion of the lower mold base driving member 33 into reciprocating motion. By adjusting the length of the first crank 341, the stroke and speed of the lower mold base 3 can be changed. The main function of the first connecting rod 342 is to transmit the reciprocating motion of the first crank 341 to the lower mold base 3, achieving precise rotation of the lower mold base 3.

[0065] The upper mold base 4 is rotatably connected to the rotating support 2 at the upper mold base rotation center 42 through the upper mold base rotation assembly 41. The upper mold base driving member 43 drives the upper mold base 4 to rotate around the upper mold base rotation center 42, achieving angle adjustment of the upper half of the mold. The upper mold base driving member 43 can be an electric motor, a hydraulic motor, or other forms of power device, which can ensure the stability and precision of the upper mold base in different positions by precisely controlling the rotation angle.

[0066] As shown in Figure 6 , the upper mold base structure of the overall mold base in one direction is shown in the schematic diagram of one embodiment of the present application; as Figure 7 shown in Figure 8 , the schematic diagram of the assembly structure of the rotating support, the upper mold base and the lower mold base of the overall mold base in another state is provided in one embodiment of the present application; as Figure 9 shown in Figure 8 , the cross-sectional view along the section line A-A is shown in Figure 10 ; as Figure 9 , the enlarged view of B in ; as

[0067] , the enlarged view of B in Figure 3 , Figures 6 to 10 As shown, the upper mold base rotation assembly 41 includes a third rotating shaft 411 and a third bearing member 412. One end of the third rotating shaft 411 is fixed to the upper mold base 4, and the third bearing member 412 is fixed to the lifting slide 25 of the rotating support 2. The other end of the third rotating shaft 411 cooperates with the third bearing member 412 to enable the upper mold base 4 to rotate. While the lifting slide 24 of the rotating support 2 performs lifting motion, it can drive the upper mold base 4 to move up and down, so that the half mold on the upper mold base 4 can realize mold closing and mold opening operation with the half mold on the lower mold base 3.

[0068] By adjusting the angle of the upper mold holder 4, the mold closing and opening process can be optimized, improving the precision and speed of reactive foam molding. For example, when producing electronic device housings, adjusting the angle of the upper mold holder can ensure tight mold closure, thereby reducing the generation of flash and burrs.

[0069] The overall rotating mold frame provided in the above embodiments of this application realizes flexible adjustment of the mold in multiple directions through a multi-layered rotating structure, which is suitable for the production of complex-shaped products; the modular design makes each component easy to disassemble and maintain, reducing maintenance costs and downtime; it is suitable for various reaction foaming molding application scenarios, such as reaction foaming molding of automotive parts.

[0070] In some embodiments of this application, see Figure 3 , Figures 6 to 10 Two upper mold frame drive components 43 are disposed on both sides of the upper mold frame 4. Each upper mold frame drive component 43 is connected to the rotating bracket 2 through the upper mold frame transmission component 44 to drive the upper mold frame 4 to rotate.

[0071] The upper mold frame drive component 43 can be fixedly mounted on the upper mold frame 4. The connection point of the upper mold frame drive component 43 and the rotating bracket 2 connected through the upper mold frame transmission component 44 is at a certain distance from the upper mold frame rotation center 42 of the upper mold frame 4, so that the upper mold frame 4 can be rotated around the upper mold frame rotation center 42 by the reaction force of the force output by the upper mold frame drive component 43 at the upper mold frame rotation center 42.

[0072] In some embodiments of this application, the upper mold frame transmission component 44 includes: a second crank 441 and a second connecting rod 442, one end of the second crank 441 being connected to the upper mold frame drive component 43; one end of the second connecting rod 442 being connected to the other end of the second crank 441, and the other end of the second connecting rod 442 being connected to the lifting slide plate 25 of the rotating bracket 2.

[0073] The main function of the second crank 441 is to convert the rotary motion of the upper mold base drive 43 into reciprocating motion. By adjusting the length of the second crank 441, the stroke and speed of the upper mold base 4 can be changed. The length and angle of the second crank 441 can be adjusted by an adjustment mechanism to adapt to different working requirements.

[0074] The main function of the second connecting rod 442 is to transmit the force generated by the reciprocating motion of the second crank 441 to the lifting slide plate 25 of the rotating support 2, and through the reaction force, to drive the rotation of the upper mold frame 4. By adjusting the length and angle of the second crank 441, the motion parameters of the upper mold frame 4 can be easily changed to adapt to different processing requirements.

[0075] The following is a description of the rotation process of the overall rotating mold frame:

[0076] Initial state:

[0077] Bottom frame 1: As the basic support structure of the whole rotary die frame, the bottom frame 1 is fixed on the ground to provide stable support.

[0078] Rotary support 2: Rotatably connected with the bottom frame 1 through the support rotating assembly 21 (including the first rotating shaft 211 and the first bearing 212), in the initial position.

[0079] Lower die frame 3: Rotatably connected with the rotary support 2 through the lower die frame rotating assembly 31 (including the second rotating shaft and the second bearing 312), in the initial position.

[0080] Upper die frame 4: Rotatably connected with the rotary support 2 through the upper die frame rotating assembly 41 (including the third rotating shaft 411 and the bearing 412), in the initial position.

[0081] Rotary action of the rotary support 2:

[0082] Starting the support drive 23: The support drive 23 (which can be an electric motor, a hydraulic motor, etc.) is started, and its output shaft drives the driving gear 241 to rotate.

[0083] Gear transmission: The driving gear 241 meshes with the arc-shaped rack 242, and the rotary motion is transmitted to the arc-shaped rack 242.

[0084] Rotation of the rotary support 2: The arc-shaped rack 242 is fixedly connected with the rotary support 2, and its movement drives the rotary support 2 to rotate around the support rotation center 22. The limiting piece 2421 limits the movement range of the arc-shaped rack 242 to prevent excessive rotation and ensure stable operation of the rotary support 2 within the predetermined working range.

[0085] Rotary action of the lower die frame 3:

[0086] Starting the lower die frame drive 33: The lower die frame drive 33 is started, and its output shaft drives the first crank 341 to rotate.

[0087] Crank connecting rod transmission: The rotary motion of the first crank 341 is transmitted to the lower die frame 3 through the first connecting rod 342.

[0088] Rotation of the lower die frame 3: The lower die frame 3 rotates around the die frame rotation center 32, realizing the angle adjustment of the lower half of the mold. The rotation angle of the lower die frame 3 can be accurately controlled by adjusting the length or rotation angle of the first crank 341.

[0089] Rotary action of the upper die frame 4:

[0090] Starting the upper die frame drive 43: The upper die frame drive 43 (which can be an electric motor, a hydraulic motor, etc.) is started, and its output shaft drives the second crank 441 to rotate.

[0092] Rotation of the upper die holder 4: the movement of the second link 442 pushes the upper die holder 4 to rotate around the upper die holder rotation center 42 through the reaction force of the force. The rotation angle of the upper die holder 4 can be accurately controlled by adjusting the length or rotation angle of the second crank 441.

[0093] Mold closing and mold opening operations:

[0094] Mold closing operation: the lifting slide 25 of the rotating bracket 2 cooperates with the guide rail 26 to perform lifting movement, driving the upper die holder 4 to move up and down. When the upper die holder 4 is lowered to the predetermined position, the half mold on the upper die holder 4 is combined with the half mold on the lower die holder 3, and the mold closing is completed.

[0095] Mold opening operation: the lifting slide 25 of the rotating bracket 2 rises, driving the upper die holder 4 to rise. When the upper die holder 4 rises to the predetermined position, the half mold on the upper die holder 4 is separated from the half mold on the lower die holder 3, and the mold opening is completed.

[0096] Through the above rotating process, the overall rotating die holder of the present application realizes multi-directional and multi-level accurate rotating movement. Through the accurate cooperation of the multi-stage transmission mechanism, the high accuracy of each die holder component in the rotating process is ensured. The multi-level rotating structure makes the die holder adapt to different production line layouts and improves the production flexibility.
