Technical Field

[0001] This utility model relates to the field of rubber automated production equipment technology, and in particular to a middle mold transfer device and a compression molding machine. Background Technology

[0002] In the existing rubber processing equipment, the process of producing rubber products involves first loading material into a mold, then transferring the mold to an opening and closing mechanism via a mold-moving device for vulcanization. The mold is then moved from the opening and closing mechanism to the loading and unloading station to remove the rubber product from the mold. However, existing rubber processing equipment uses a side-transfer method for the intermediate mold and requires spaced safety passages within the equipment, thus increasing the width of the equipment and its floor space. Utility Model Content

[0003] The main purpose of this utility model is to propose a middle mold moving device and a compression molding machine, which aims to reduce the floor space occupied by the compression molding machine.

[0004] To achieve the above objectives, the present invention proposes a mid-mold transfer device, applied to a compression molding machine. The compression molding machine includes a mold closing device, and the mid-mold transfer device includes a base for mounting above the mold closing device; a first transfer mechanism disposed on the base; a second transfer mechanism disposed on the first transfer mechanism, located above the first transfer mechanism; and a tilting mechanism located below the second transfer mechanism. The first transfer mechanism drives and connects the second transfer mechanism and the tilting mechanism, and the second transfer mechanism drives and connects the tilting mechanism. The first transfer mechanism is used to carry... The second mold-moving mechanism and the flipping mechanism are moved along a first direction, so that the distance by which the second mold-moving mechanism and the flipping mechanism extend beyond the first mold-moving mechanism along the first direction is adjustable. The second mold-moving mechanism is used to drive the flipping mechanism to move along a second direction to the mold-closing and forming device, so that the mold in the flipping mechanism is transported to the mold-closing and forming device. The second mold-moving mechanism is also used to drive the flipping mechanism to move along the second direction from the mold-closing and forming device to one side of the first mold-moving mechanism. The flipping mechanism is used to install the mold in the mold and drive the mold in the mold to rotate. The first direction intersects with the second direction.

[0005] In one embodiment, the flipping mechanism includes a first mounting base and flipping plates disposed on both sides of the first mounting base. A second mold moving mechanism is driven and connected to the first mounting base. The flipping plates are rotatably connected to the first mounting base. The two flipping plates enclose an installation space for installing the middle mold of the mold, so that the flipping plates can drive the middle mold of the mold to rotate.

[0006] In one embodiment, the flipping mechanism further includes a second mounting base and a limiting member disposed on the second mounting base. The second mounting base is disposed on the first mold moving mechanism, and the limiting member is rotatably disposed on the second mounting base. The limiting member is inclined from the second mounting base toward the flipping plate, and the limiting member is used to abut against the flipping plate to restrict the flipping plate from moving along the second direction and drive the flipping plate to rotate.

[0007] In one embodiment, the flipping mechanism further includes a first rotating shaft, one end of the flipping plate is rotatably connected to the first mounting base through the first rotating shaft, the end of the first mounting base away from the first rotating shaft has a snap-fit ​​groove, the flipping plate is provided with a first snap-fit ​​part, and the flipping plate is snapped into the snap-fit ​​groove through the first snap-fit ​​part.

[0008] In one embodiment, the first mold-moving mechanism includes a mounting bracket and a drive assembly disposed on the mounting bracket. The mounting bracket is movably disposed on the base along the first direction. The second mold-moving mechanism is disposed on the mounting bracket. The flipping mechanism is disposed on the side of the mounting bracket away from the second mold-moving mechanism. The drive assembly drives and connects to the mounting bracket so that the mounting bracket can move along the first direction.

[0009] In one embodiment, the first mold moving mechanism further includes slide rails disposed on both sides of the base, the driving assembly includes a first transmission member and a driving member, the slide rails extend along the first direction, the first transmission member is disposed between the two slide rails, the driving member drives and connects to the first transmission member, the mounting bracket has sliding portions on both sides, and the mounting bracket is slidably connected to the slide rails through the sliding portions.

[0010] In one embodiment, the mounting bracket includes a first connecting arm, a second connecting arm, and a connector. The first connecting arm and the second connecting arm extend along the first direction. The first connecting arm is connected to the second connecting arm through the connector. The first connecting arm and the second connecting arm are respectively provided with the sliding portion. The first connecting arm and the second connecting arm are slidably connected to the slide rail through the sliding portion.

[0012] In one embodiment, the transmission assembly further includes a guide rod, a second rotating shaft, and transmission gears disposed at both ends of the second rotating shaft. The guide rod is movably disposed on the mounting portion and extends along the second direction. The guide rod has a threaded portion, and the transmission gears are connected to the threaded portion in a transmission connection.

[0013] This utility model also proposes a molding machine, including a middle mold moving device as described in any of the above embodiments.

[0014] The technical solution of this utility model employs a second mold-moving mechanism to drive a flipping mechanism to reciprocate along a second direction. The second mold-moving mechanism can move the middle mold of the mold to the mold-closing and forming device. The second mold-moving mechanism can also drive the middle mold of the mold on the mold-closing and forming device to return to the initial position on one side of the first mold-moving mechanism. When the middle mold of the mold returns to the initial position, the flipping mechanism drives the middle mold of the mold to rotate, thereby preventing the middle mold of the mold from colliding with other parts during the reset process of the first moving mechanism. By setting the middle mold moving device above the mold-closing and forming device, the middle mold of the mold is transported from above the mold-closing and forming device to the mold-closing and forming device, replacing the existing compression molding machine's method of transferring the middle mold from the side. This avoids the need for safety passages to be set at intervals inside the compression molding machine and reduces the footprint of the compression molding machine. The first mold-moving mechanism drives the second mold-moving mechanism and the flipping mechanism to move along a first direction, so that the distance by which the second mold-moving mechanism and the flipping mechanism extend beyond the first mold-moving mechanism along the first direction is adjustable. This allows the second mold-moving mechanism and the flipping mechanism to provide at least two different extension distances for the mold-moving stroke, thereby better adapting to the different distances of mold-moving strokes required by the mold-closing and forming device.

[0028] This utility model proposes a medium mold moving device 100.

[0029] Please see Figures 1 to 4 In one embodiment of this utility model, the intermediate mold transfer device 100 includes a base 1, a first mold transfer mechanism 2, a second mold transfer mechanism 3, and a flipping mechanism 4. The base 1 is used to be installed above the mold closing and forming device; the first mold transfer mechanism 2 is disposed on the base 1. The second mold transfer mechanism 3 is disposed on the first mold transfer mechanism 2, and the second mold transfer mechanism 3 is located above the first mold transfer mechanism 2. The flipping mechanism 4 is located below the second mold-moving mechanism 3. The first mold-moving mechanism 2 drives and connects the second mold-moving mechanism 3 and the flipping mechanism 4. The second mold-moving mechanism 3 drives and connects the flipping mechanism 4. The first mold-moving mechanism 2 is used to drive the second mold-moving mechanism 3 and the flipping mechanism 4 to move along a first direction, so that the distance by which the second mold-moving mechanism 3 and the flipping mechanism 4 extend beyond the first mold-moving mechanism 2 along the first direction is adjustable. The second mold-moving mechanism 3 is used to drive the flipping mechanism 4 to move along a second direction to the mold-closing and forming device, so that the mold in the middle of the mold on the flipping mechanism 4 is transported to the mold-closing and forming device. The second mold-moving mechanism 3 is also used to drive the flipping mechanism 4 to move along the second direction from the mold-closing and forming device to one side of the first mold-moving mechanism 2. The flipping mechanism 4 is used to install the mold in the middle and drive the mold in the middle to rotate, wherein the first direction intersects with the second direction.

[0030] The technical solution of this utility model employs a second mold-moving mechanism 3 to drive a flipping mechanism 4 to reciprocate along a second direction. The second mold-moving mechanism 3 can move the middle mold of the mold to the mold-closing and forming device. The second mold-moving mechanism 3 can also drive the middle mold of the mold on the mold-closing and forming device to return to the initial position on one side of the first mold-moving mechanism 2. When the middle mold of the mold returns to the initial position, the flipping mechanism 4 drives the middle mold of the mold to rotate, thereby preventing the middle mold of the mold from colliding with other parts during the reset process of the first moving mechanism. By setting the middle mold moving device 100 to be installed above the mold-closing and forming device, the middle mold of the mold can move from the mold-closing and forming device... The material is conveyed from above to the mold-forming device, replacing the existing compression molding machine's method of transferring the middle mold from the side. This avoids the need for safety passages to be set at intervals inside the compression molding machine and reduces the footprint of the compression molding machine. The first mold-moving mechanism 2 drives the second mold-moving mechanism 3 and the flipping mechanism 4 to move along the first direction, so that the distance by which the second mold-moving mechanism 3 and the flipping mechanism 4 extend beyond the first mold-moving mechanism 2 along the first direction is adjustable. This allows the second mold-moving mechanism 3 and the flipping mechanism 4 to provide at least two different mold-moving strokes with different extension distances, thereby better adapting to the different mold-moving strokes required by the compression molding device.

[0031] In this embodiment, the compression molding machine also includes a mold closing device located below the middle mold moving device 100. The mold closing device is used to install the upper mold and the lower mold, while the middle mold moving device 100 is used to transport the middle mold to between the upper mold and the lower mold. The mold closing device is also used to perform vulcanization processing after closing the upper mold, the middle mold, and the lower mold. This application, by setting the middle mold moving device 100 above the mold closing device, allows the middle mold to be transported from above the mold closing device into the mold closing device, replacing the existing method of transporting the middle mold from the sides of the mold closing device. This reduces the floor space required for installing the middle mold moving device 100 on both sides of the compression molding machine, and improves the space utilization rate of the compression molding machine by making reasonable use of the space above the mold closing device. The mold-moving stroke of the first mold-moving mechanism 2 can be set to a distance by which the first mold-moving mechanism 2 drives the second mold-moving mechanism 3 and the flipping mechanism 4 to extend beyond the first mold-moving mechanism 2. This application employs the first mold-moving mechanism 2 to drive the second mold-moving mechanism 3 and the flipping mechanism 4 to reciprocate along a first direction, thereby making the mold-moving stroke of the intermediate mold-moving device 100 adjustable. The first mold-moving mechanism 2 may have a first position and a second position. When the first mold-moving mechanism 2 is in the first position, the size of the mold-moving stroke is smaller than that when the first mold-moving mechanism 2 is in the second position, thus enabling the intermediate mold-moving device 100 to provide at least two different mold-moving stroke distances. The second mold-moving mechanism 3 can drive the flipping mechanism 4 to reciprocate along a second direction, thereby transporting the intermediate mold on the flipping mechanism 4 to the mold-closing and forming device, making it easier for the intermediate mold-moving device 100 to move the intermediate mold to the mold-closing and forming device. After the upper mold, middle mold, and lower mold have completed the vulcanization process, the second mold moving mechanism 3 and the flipping mechanism 4 are also used to move the middle mold on the mold closing and forming device to the initial position located on one side of the first mold moving 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, so as to make it easier for the first mold moving mechanism 2 to drive the second mold moving mechanism 3, the flipping mechanism 4, and the middle mold to move along the side away from the mold closing and forming device.

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

[0033] In this embodiment, the second direction can be the same as the up and down direction. The first mounting base 41 is located below the second mold-moving mechanism 3 and above the mold-closing and forming device, so that the flipping mechanism 4 can transport the mold middle part to the mold-closing and forming device when it reciprocates along the second direction, or can move the mold middle part from the mold-closing and forming device to the initial position when it reciprocates along the second direction. The second mold-moving mechanism 3 is driven and connected to the first mounting base 41. Under the drive of the second mold-moving mechanism 3, the first mounting base 41 and the flipping plate 42 can reciprocate along the second direction, which makes it easier for the mold middle part to move to the mold-closing and forming device or to transfer from the mold-closing and forming device to the flipping plate 42, thereby improving the mold-moving efficiency of the mold middle part moving device 100. In order to facilitate the mold middle part being clamped relative to the first mounting base 41 when it is in the initial position, so as to avoid the mold middle part colliding with other components, the flipping plate 42 is rotatably connected to the first mounting base 41. The flipping plate 42 is used to drive the mold middle part to rotate when the second mold-moving mechanism 3 drives the first mounting base 41 to move to the initial position. To improve the stability of the mold connection, this application uses two flip plates 42 installed at intervals on both sides of the first mounting base 41. The two flip plates 42 enclose a mounting space 421 for installing the mold, so that the mold can be detachably installed on the flip plates 42, and the mold is located in the mounting space 421.

[0034] like Figure 5 and Figure 6 As shown, in one embodiment, the flipping mechanism 4 further includes a second mounting base 43 and a limiting member 44 disposed on the second mounting base 43. The second mounting base 43 is disposed on the first mold moving mechanism 2, and the limiting member 44 is rotatably disposed on the second mounting base 43. The limiting member 44 is inclined from the second mounting base 43 toward the flipping plate 42. The limiting member 44 is used to abut against the flipping plate 42 to restrict the flipping plate 42 from moving along the second direction and to drive the flipping plate 42 to rotate.

[0035] In this embodiment, the second mounting base 43 is disposed on the first mold-moving mechanism 2, and the limiting member 44 is located above any end of the flipping plate 42. The limiting member 44 is rotatably connected to the second mounting base 43 and is disposed at one end of the mold middle mold. When the second mold-moving mechanism 3 drives the flipping mechanism 4 to move to the initial position, the limiting member 44 is limited and abuts against one end of the mold middle mold. When the second mold-moving mechanism 3 drives the flipping mechanism 4 to continue moving upward, one end of the mold middle mold is subjected to force, and the limiting member 44 can rotate synchronously with the mold middle mold, so that the mold middle mold and the limiting member 44 rotate synchronously. In order to facilitate the flipping mechanism 4 to drive the mold to flip, the limiting member 44 is inclined from the second mounting base 43 toward the flipping plate 42. Under the drive of the second mold-moving mechanism 3, the mold middle mold gradually abuts against the limiting member 44. When the mold middle mold and the limiting member 44 are completely in contact, the limiting member 44 can rotate synchronously with the mold middle mold, so that the mold middle mold is set at an angle with the first mounting base 41 after resetting.

[0036] like Figure 5 and Figure 6 As shown, in one embodiment, the flipping mechanism 4 further includes a first rotating shaft 45. One end of the flipping plate 42 is rotatably connected to the first mounting base 41 through the first rotating shaft 45. The end of the first mounting base 41 away from the first rotating shaft 45 has a snap-fit ​​groove 411. The flipping plate 42 is provided with a first snap-fit ​​part 422. The flipping plate 42 is snapped into the snap-fit ​​groove 411 through the first snap-fit ​​part 422.

[0037] In this embodiment, one end of the first rotating shaft 45 is rotatably connected to one end of the flipping plate 42, and the other end of the first rotating shaft 45 is rotatably connected to the first mounting base 41, thereby facilitating the rotatable connection between the flipping plate 42 and the first mounting base 41. The flipping mechanism 4 also includes at least two first bearings. The two ends of the first rotating shaft 45 can be equipped with first bearings. One first bearing can be located at the connection between the first rotating shaft 45 and the flipping plate 42, and the other first bearing can be located at the connection between the first rotating shaft 45 and the first mounting base 41, thereby improving the stability of the connection between the first rotating shaft 45 and the flipping plate 42 and the first mounting base 41, respectively. In order to improve the stability of the connection between the flipping plate 42 and the first mounting base 41, the end of the first mounting base 41 away from the first rotating shaft 45 has a snap-fit ​​groove 411, and the flipping plate 42 is provided with a first snap-fit ​​part 422. The flipping plate 42 is snapped into the snap-fit ​​groove 411 through the first snap-fit ​​part 422. One end of the flip plate 42 is detachably connected to the first mounting base 41, and the other end of the flip plate 42 is rotatably connected to the first mounting base 41. The limiting member 44 is provided on the side of the first mold moving mechanism 2 near the first rotating shaft 45, so that when the mold middle mold and the limiting member 44 are in a limiting contact, the end of the flip plate 42 near the first rotating shaft 45 is subjected to force, and the end of the flip plate 42 near the first snap-fit ​​part 422 is separated from the snap-fit ​​groove 411, thereby making it easier for the mold middle mold, the flip plate 42 and the limiting member 44 to rotate synchronously.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the first mold-moving mechanism 2 includes a mounting bracket 21 and a driving component 22 disposed on the mounting bracket 21. The mounting bracket 21 is movably disposed on the base 1 along the first direction. The second mold-moving mechanism is disposed on the mounting bracket 21. The flipping mechanism 4 is disposed on the side of the mounting bracket 21 away from the second mold-moving mechanism. The driving component 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, making it easier for the mounting bracket 21 to move along the first direction under the drive of the drive assembly 22. The other end of the mounting bracket 21 is equipped with the second mold transfer mechanism 3 and the flipping mechanism 4. By setting the mounting bracket 21 as the connection structure between the first mold transfer mechanism 2 and the second mold transfer mechanism 3, it is easier for the first mold transfer mechanism 2 to simultaneously drive the second mold transfer mechanism 3 and the flipping mechanism 4 to move along the first direction, so that the distance of the second mold transfer mechanism 3 and the flipping mechanism 4 extending out of the base 1 is adjustable, and it is easier to adjust the mold transfer stroke of the first mold transfer mechanism 2. The intermediate mold transfer device 100 can be adapted to various mold closing and forming devices with different mold transfer strokes, improving the versatility of the intermediate mold transfer device 100.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the first mold moving mechanism 2 further includes slide rails 23 disposed on both sides of the base 1. The driving component 22 includes a first transmission member 221 and a driving member 222. The slide rails 23 extend along the first direction. The first transmission member 221 is disposed between the two slide rails 23. The driving member 222 drives and connects to the first transmission member 221. The mounting bracket 21 has sliding portions 211 on both sides. The mounting bracket 21 is slidably connected to the slide rails 23 through the sliding portions 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 two slide rails 23 one-to-one through the two sliding portions 211, thereby improving the stability of the mounting bracket 21 sliding on the base 1. In order to improve the stability of the driving assembly 22 driving the mounting bracket 21 to slide along the first direction, the 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 along the first direction. The driving member 222 is connected to the first transmission member 221 through the driving gear. The driving member 222 drives the driving gear to reciprocate along the first transmission member 221 in the first direction, thereby driving the mounting bracket 21 to reciprocate along the first direction. The driving member 222 may be a driver such as a drive motor or a motor driver. The first transmission member 221 may also be a linear transmission member such as a lead 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 connector 214. The first connecting arm 212 and the second connecting arm 213 extend along the first direction. The first connecting arm 212 is connected to the second connecting arm 213 through the connector 214. The first connecting arm 212 and the second connecting arm 213 are respectively provided with sliding portions 211. The first connecting arm 212 and the second connecting arm 213 are slidably connected to the slide rail 23 through the sliding portions 211.

[0043] In this embodiment, the mounting bracket 21 includes a first connecting arm 212, a second connecting arm 213, and a connector 214 disposed between the first connecting arm 212 and the second connecting arm 213. The driver can be mounted on the connector 214. The first connecting arm 212 and the second connecting arm 213 extend along a first direction. The first connecting arm 212 and the second connecting arm 213 are slidably connected to the slide rail 23 through the sliding part 211, respectively. The second mold moving 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 part 211, which further improves the stability of the mounting bracket 21 connected to the base 1, the second mold moving mechanism 3 and the flipping mechanism 4, respectively.

[0044] like Figures 1 to 3 As shown, in one embodiment, the second mold-moving mechanism includes a transmission component 31 and a cylinder 32. The mounting bracket 21 is provided with a mounting portion 215. The cylinder 32 drives and connects to the flipping mechanism 4. The transmission component 31 is disposed in the mounting portion 215.

[0045] In this embodiment, cylinder 32 can be mounted on mounting bracket 21. The driving end of cylinder 32 is driven by the flipping mechanism 4. Under the drive of cylinder 32, the flipping mechanism 4 can reciprocate along the second direction. To further improve the stability of the movement of the flipping mechanism 4 driven by cylinder 32, two cylinders 32 can be provided and respectively mounted on both sides of mounting bracket 21. This application also uses a transmission assembly 31 mounted on the mounting part 215 of mounting bracket 21. The transmission assembly 31 is used to ensure the consistency of the reciprocating movement of the two flipping plates 42 along the second direction.

[0046] like Figure 2 As shown, in one embodiment, the transmission assembly 31 further includes a guide rod 311, a second rotating shaft 312, and transmission gears 313 disposed at both ends of the second rotating shaft 312. The guide rod 311 is movably disposed on the mounting portion 215. The guide rod 311 extends along the second direction and is provided with a threaded portion 3111. The transmission gears 313 are connected to the threaded portion 3111 in a transmission connection.

[0047] In this embodiment, the guide rod 311 is movably inserted through the mounting portion 215 in the second direction. The guide rod 311 extends in the second direction and guides the driving direction of the cylinder 32 and the moving direction of the flipping mechanism 4, thereby causing the flipping mechanism 4 to reciprocate in the second direction and improving the stability of the flipping mechanism 4 in the second direction. To further improve the consistency of the reciprocating movement of the two flipping plates 42 in the second direction, the guide rod 311 may be provided with a threaded portion 3111. The two ends of the second rotating shaft 312 are respectively connected to the threaded portion 3111 through transmission gears 313, thereby ensuring that the two flipping plates 42 maintain the same position during movement and avoiding the positional deviation of the two flipping plates 42 from affecting the mold conveying to the mold closing and forming device.

[0048] This utility model also proposes a compression molding machine, which includes a mold closing and forming device and a middle mold moving device 100. The specific structure of the middle mold moving device 100 is as described in the above embodiments. Since this compression molding machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The mold closing and forming device is located below the middle mold moving device 100.

[0049] In one embodiment, the mold clamping and forming device (not shown) includes a third mounting base, with mounting positions on both sides of the third mounting base.
