[0028] The present invention provides a middle mold transfer device 100 .

[0029] See also Figures 1 to 4 In one embodiment of the present invention, the middle mold shifting device 100 includes a base 1, a first mold shifting mechanism 2, a second mold shifting mechanism 3, and a flipping mechanism 4. The base 1 is mounted above the mold clamping device; the first mold shifting mechanism 2 is mounted on the base 1. The second mold shifting mechanism 3 is mounted on the first mold shifting mechanism 2 and is located above the first mold shifting mechanism 2. The flipping mechanism 4 is located below the second mold shifting mechanism 3, the first mold shifting mechanism 2 is driven to connect the second mold shifting mechanism 3 and the flipping mechanism 4, the second mold shifting mechanism 3 is driven to connect the flipping mechanism 4, the first mold shifting mechanism 2 is used to drive the second mold shifting mechanism 3 and the flipping mechanism 4 to move along the first direction, so that the distance by which the second mold shifting mechanism 3 and the flipping mechanism 4 extend out of the first mold shifting mechanism 2 along the first direction is adjustable, the second mold shifting mechanism 3 is used to drive the flipping mechanism 4 to move along the second direction to the mold clamping and molding device, so that the mold on the flipping mechanism 4 is transported to the mold clamping and molding device, the second mold shifting mechanism 3 is also used to drive the flipping mechanism 4 to move along the second direction from the mold clamping and molding device to one side of the first mold shifting mechanism 2, the flipping mechanism 4 is used for the mold mold to be installed and drive the mold mold to rotate, wherein the first direction intersects with the second direction.

[0030] The technical solution of the present invention adopts the second mold shifting mechanism 3 to drive the flipping mechanism 4 to move back and forth along the second direction. The second mold shifting mechanism 3 can drive the mold middle mold to move to the mold clamping and molding device. The second mold shifting mechanism 3 can also drive the mold middle mold on the mold clamping and molding device to reset to the initial position on the side of the first mold shifting mechanism 2. The flipping mechanism 4 drives the mold middle mold to rotate when the mold middle mold is reset to the initial position, thereby preventing the mold middle mold from colliding with other components during the reset process of the first moving mechanism; by arranging the mold middle mold shifting device 100 to be installed above the mold clamping and molding device, the mold middle mold can be moved from the mold clamping and molding device The mold is transported from the top to the mold closing device, replacing the existing compression molding machine's method of transferring the middle mold from the side, thereby avoiding the need for a safety passage to be set up in the compression molding machine, and reducing the floor space of the compression molding machine; the first mold shifting mechanism 2 drives the second mold shifting mechanism 3 and the flipping mechanism 4 to move along the first direction, so that the distance by which the second mold shifting mechanism 3 and the flipping mechanism 4 extend from the first mold shifting mechanism 2 along the first direction is adjustable, thereby enabling the second mold shifting mechanism 3 and the flipping mechanism 4 to provide at least two mold shifting strokes with different extension distances, thereby better adapting to the mold shifting strokes of different distances required by the mold closing device.

[0031] In this embodiment, the compression molding machine further includes a mold-closing and molding device located below the middle mold-shifting device 100. The mold-closing and molding device is used to install the upper mold and the lower mold, and the middle mold-shifting device 100 is used to transport the middle mold to between the upper mold and the lower mold. The mold-closing and molding device is also used to perform a vulcanization process after the upper mold, the middle mold, and the lower mold are clamped. This application arranges the middle mold-shifting device 100 above the mold-closing and molding device so that the middle mold is transported from above the mold-closing and molding device into the mold-closing and molding device, replacing the existing method of transporting the middle mold from both sides of the mold-closing and molding device by the middle mold-shifting device 100. This reduces the area required for installing the middle mold-shifting device 100 on both sides of the compression molding machine, and improves the space utilization rate of the compression molding machine by rationally utilizing the space above the mold-closing and molding device. The mold shifting stroke of the first mold shifting mechanism 2 can be set to the distance that the first mold shifting mechanism 2 drives the second mold shifting mechanism 3 and the flipping mechanism 4 to extend beyond the first mold shifting mechanism 2. In this application, the first mold shifting mechanism 2 is configured to drive the second mold shifting mechanism 3 and the flipping mechanism 4 to move back and forth in a first direction, thereby enabling the mold shifting stroke of the middle mold shifting device 100 to be adjustable. The first mold shifting mechanism 2 can have a first position and a second position. When the first mold shifting mechanism 2 is in the first position, the mold shifting stroke is smaller than when the first mold shifting mechanism 2 is in the second position. This allows the middle mold shifting device 100 to provide at least two different mold shifting strokes. The second mold shifting mechanism 3 can drive the flipping mechanism 4 to move back and forth in the second direction, thereby transporting the mold center die on the flipping mechanism 4 to the mold closing and molding device, making it easier for the middle mold shifting device 100 to move the mold center die to the mold closing and molding device. After the upper mold, the middle mold and the lower mold complete the vulcanization process, the second mold shifting mechanism 3 and the flipping mechanism 4 are also used to move the middle mold on the mold closing and molding device to the initial position located on the side of the first mold shifting mechanism 2 along the first direction. The flipping mechanism 4 is also used to drive the middle mold to rotate when the middle mold is reset to the initial position, thereby making it more convenient for the first mold shifting mechanism 2 to drive the second mold shifting mechanism 3, the flipping mechanism 4 and the middle mold to move along the side away from the mold closing and molding device.

[0032] like Figure 4 and Figure 5 As shown, in one embodiment, the flip mechanism 4 includes a first mounting seat 41 and flip plates 42 arranged on both sides of the first mounting seat 41. The second mold shifting mechanism 3 is driven and connected to the first mounting seat 41. The flip plates 42 are rotatably connected to the first mounting seat 41. The two flip plates 42 enclose an installation space 421 for installing the mold middle mold, so that the flip plates 42 can drive the mold middle mold to rotate.

[0033] In this embodiment, the second direction can be consistent with the up-down direction. The first mounting seat 41 is located below the second mold shifting mechanism 3, and the first mounting seat 41 is located above the mold clamping and molding device, so that the flip mechanism 4 can transfer the mold center mold to the mold clamping and molding device when reciprocating in the second direction, or the flip mechanism 4 can move the mold center mold from the mold clamping and molding device to the initial position when reciprocating in the second direction. The second mold shifting mechanism 3 is driven by the first mounting seat 41. Driven by the second mold shifting mechanism 3, the first mounting seat 41 and the flip plate 42 can reciprocate in the second direction, thereby facilitating the movement of the mold center mold to the mold clamping and molding device or from the mold clamping and molding device to the flip plate 42, thereby improving the mold shifting efficiency of the mold center shifting device 100. In order to facilitate the clamping arrangement of the mold center mold relative to the first mounting seat 41 when in the initial position to prevent the mold center mold from colliding with other components, the flip plate 42 is rotatably connected to the first mounting seat 41. The flip plate 42 is used to drive the mold center mold to rotate when the second mold shifting mechanism 3 drives the first mounting seat 41 to move to the initial position. In order to improve the stability of the mold-mold connection, the present application uses two flip plates 42 installed at intervals on both sides of the first mounting seat 41. The two flip plates 42 enclose an installation space 421 for installing the mold-mold, so that the mold-mold can be detachably installed on the flip plate 42, so that the module group mold is located in the installation space 421.

[0034] like Figure 5 and Figure 6 As shown, in one embodiment, the flip mechanism 4 also includes a second mounting seat 43 and a limiting member 44 provided on the second mounting seat 43. The second mounting seat 43 is provided on the first mold shifting mechanism 2. The limiting member 44 is rotatably provided on the second mounting seat 43. The limiting member 44 is tilted from the second mounting seat 43 toward the flip plate 42. The limiting member 44 is used to abut against the flip plate 42 to limit the movement of the flip plate 42 along the second direction and drive the flip plate 42 to rotate.

[0035] In this embodiment, a second mounting seat 43 is provided on the first mold shifting mechanism 2, and a stopper 44 is positioned above either end of the flip plate 42. The stopper 44 is rotatably connected to the second mounting seat 43 and is provided at one end of the mold center. When the second mold shifting mechanism 3 drives the flip mechanism 4 to its initial position, the stopper 44 engages one end of the mold center. As the second mold shifting mechanism 3 drives the flip mechanism 4 to continue moving upward, a force is applied to one end of the mold center, causing the stopper 44 to rotate synchronously with the mold center, thereby causing the mold center and the stopper 44 to rotate synchronously. To facilitate flipping of the mold by the flip mechanism 4, the stopper 44 is tilted from the second mounting seat 43 toward the flip plate 42. Driven by the second mold shifting mechanism 3, the mold center gradually engages the stopper 44. When the mold center and the stopper 44 are fully aligned, the stopper 44 rotates synchronously with the mold center, ensuring that the mold center is positioned at an angle to the first mounting seat 41 after restoration.

[0036] like Figure 5 and Figure 6 As shown, in one embodiment, the flip mechanism 4 also includes a first rotating shaft 45, one end of the flip plate 42 is rotatably connected to the first mounting seat 41 through the first rotating shaft 45, and the first mounting seat 41 has a clamping groove 411 at one end away from the first rotating shaft 45, and the flip plate 42 is provided with a first clamping portion 422, and the flip plate 42 is clamped in the clamping groove 411 through the first clamping portion 422.

[0037] In this embodiment, one end of the first rotating shaft 45 is rotatably connected to one end of the flip plate 42, and the other end of the first rotating shaft 45 is rotatably connected to the first mounting seat 41, thereby facilitating the rotational connection between the flip plate 42 and the first mounting seat 41. The flip mechanism 4 also includes at least two first bearings. First bearings may be installed at both ends of the first rotating shaft 45. One of the first bearings may be located at the connection between the first rotating shaft 45 and the flip plate 42, and the other first bearing may be located at the connection between the first rotating shaft 45 and the first mounting seat 41, thereby improving the stability of the connection between the first rotating shaft 45 and the flip plate 42 and the first mounting seat 41, respectively. In order to improve the stability of the connection between the flip plate 42 and the first mounting seat 41, the first mounting seat 41 has a snap-fitting groove 411 at one end away from the first rotating shaft 45. The flip plate 42 is provided with a first snap-fitting portion 422. The flip plate 42 is snap-fitted into the snap-fitting groove 411 via the first snap-fitting portion 422. One end of the flip plate 42 is detachably connected to the first mounting seat 41, and the other end of the flip plate 42 is rotatably connected to the first mounting seat 41. The limiter 44 is provided on the side of the first mold shifting mechanism 2 close to the first rotating shaft 45, so that when the mold center mold is limitedly abutted against the limiter 44, the end of the flip plate 42 close to the first rotating shaft 45 is subjected to force, and the end of the flip plate 42 close to the first clamping portion 422 is separated from the clamping groove 411, thereby making it easier for the mold center mold, the flip plate 42 and the limiter 44 to rotate synchronously.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the first mold shifting mechanism 2 includes a mounting bracket 21 and a driving assembly 22 provided on the mounting bracket 21, the mounting bracket 21 is movably provided on the base 1 along the first direction, the second mold shifting assembly is provided on the mounting bracket 21, the flipping mechanism 4 is provided on a side of the mounting bracket 21 away from the second mold shifting assembly, and the driving assembly 22 drives the mounting bracket 21 to move the mounting bracket 21 along the first direction.

[0039] In this embodiment, one end of the mounting bracket 21 is movably mounted on the base 1 along the first direction, facilitating movement of the mounting bracket 21 along the first direction driven by the drive assembly 22. The second mold shifting mechanism 3 and the flipping mechanism 4 are mounted on the other end of the mounting bracket 21. By providing the mounting bracket 21 as a connecting structure between the first and second mold shifting mechanisms 2 and 3, the first mold shifting mechanism 2 can simultaneously drive the second mold shifting mechanism 3 and the flipping mechanism 4 to move along the first direction. This allows for adjustable extension distances of the second mold shifting mechanism 3 and the flipping mechanism 4 from the base 1, further facilitating adjustment of the mold shifting stroke of the first mold shifting mechanism 2. The middle mold shifting device 100 is adaptable to a variety of mold-closing molding devices with different mold shifting strokes, thereby enhancing the versatility of the middle mold shifting device 100.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the first mold shifting mechanism 2 also includes slide rails 23 provided on both sides of the base 1, the driving assembly 22 includes a first transmission member 221 and a driving member 222, the slide rails 23 are extended along the first direction, the first transmission member 221 is provided between the two slide rails 23, the driving member 222 drives and connects the first transmission member 221, and sliding parts 211 are provided on both sides of the mounting bracket 21, and the mounting bracket 21 is slidably connected to the slide rails 23 through the sliding parts 211.

[0041] In this embodiment, sliding portions 211 may be provided on both sides of the bottom of the mounting bracket 21. The mounting bracket 21 is slidably connected to the two slide rails 23 via the two sliding portions 211, thereby improving the stability of the mounting bracket 21 sliding on the base 1. To improve the stability of the drive assembly 22 driving the mounting bracket 21 to slide in the first direction, a driving member 222 is provided on the mounting bracket 21. The driving end of the driving member 222 may be equipped with a driving gear. The first transmission member 221 may be a rack extending in the first direction. The driving member 222 is connected to the first transmission member 221 via the driving gear. The driving member 222 drives the driving gear to reciprocate on the first transmission member 221 in the first direction, thereby driving the mounting bracket 21 to reciprocate in the first direction. The driving member 222 may be configured as a driver such as a drive motor, and the first transmission member 221 may also be configured as a linear transmission member such as a screw.

[0042] like Figure 2 As shown, in one embodiment, the mounting bracket 21 includes a first connecting arm 212, a second connecting arm 213 and a connecting member 214, the first connecting arm 212 and the second connecting arm 213 are extended along the first direction, the first connecting arm 212 is connected to the second connecting arm 213 through the connecting member 214, the first connecting arm 212 and the second connecting arm 213 are respectively provided with the sliding part 211, and the first connecting arm 212 and the second connecting arm 213 are slidably connected to the slide rail 23 through the sliding part 211.

[0043] In this embodiment, the mounting bracket 21 includes a first connecting arm 212, a second connecting arm 213 and a connecting member 214 arranged between the first connecting arm 212 and the second connecting arm 213. The driver can be installed on the connecting member 214. The first connecting arm 212 and the second connecting arm 213 are extended along the first direction. The first connecting arm 212 and the second connecting arm 213 are respectively slidably connected to the slide rail 23 through the sliding portion 211. The second mold shifting mechanism 3 and the flipping mechanism 4 are respectively installed on the side of the first connecting arm 212 and the second connecting arm 213 away from the sliding portion 211, thereby further improving the stability of the connection between the mounting bracket 21 and the base 1, the second mold shifting mechanism 3 and the flipping mechanism 4.

[0044] like Figures 1 to 3 As shown, in one embodiment, the second mold shifting assembly includes a transmission assembly 31 and a cylinder 32 , the mounting bracket 21 is provided with a mounting portion 215 , the cylinder 32 is driven and connected to the flipping mechanism 4 , and the transmission assembly 31 is provided in the mounting portion 215 .

[0045] In this embodiment, the cylinder 32 can be mounted on the mounting bracket 21. The driving end of the cylinder 32 is drivably connected to the flip mechanism 4. Driven by the cylinder 32, the flip mechanism 4 can reciprocate in the second direction. To further improve the stability of the cylinder 32-driven movement of the flip mechanism 4, two cylinders 32 can be provided, one mounted on each side of the mounting bracket 21. This application also utilizes a transmission assembly 31 mounted on the mounting portion 215 of the mounting bracket 21.

The guide rod 311 is provided with a threaded portion 3111, and the transmission gear 313 is transmission-connected to the threaded portion 3111.

[0047] In this embodiment, a guide rod 311 is disposed through the mounting portion 215 so as to be movable in the second direction. The guide rod 311 extends in the second direction and serves to guide the driving direction of the air cylinder 32 and the movement direction of the flip mechanism 4, thereby enabling the flip mechanism 4 to reciprocate in the second direction and improving the stability of the flip mechanism 4's movement in the second direction. To further improve the consistency of the reciprocating movement of the two flip plates 42 in the second direction, the guide rod 311 may be provided with a threaded portion 3111. The ends of the second rotating shaft 312 are respectively connected to the threaded portion 3111 via a transmission gear 313. This ensures that the two flip plates 42 maintain the same position during movement, preventing the positions of the two flip plates 42 from shifting and affecting the transport of the mold from the mold to the mold-closing molding device.

[0048] The present invention also provides a compression molding machine comprising a mold-closing device and a middle mold-shifting device 100.
