[0026] This utility model proposes a mold moving device.
[0027] Please see Figures 1 to 4In one embodiment of the present invention, the mold-shifting device is applied to a compression molding machine, and the mold-shifting device includes a base 1 and at least two mold-shifting crossbeam assemblies 2. The base 1 has mounting positions 11 on both sides, and each mounting position 11 is provided with a first mounting part 111 and a second mounting part 112. The first mounting part 111 and the second mounting part 112 are arranged along a first direction. The mold moving beam assembly 2 is used for mold sliding. The mold moving beam assembly 2 includes a first mold moving beam 21 and a second mold moving beam 22 that are detachably disposed from the base 1. The mold moving beam assembly 2 has a first working state and a second working state. In the first working state, the first mold moving beam 21 is mounted on the first mounting part 111, and the second mold moving beam 22 is mounted on the second mounting part 112. The first mold moving beam 21 and the second mold moving beam 22 are arranged along the first direction. In the second working state, the mold moving beam assembly 2 is also used such that the second mold moving beam 22 is detached from the base 1, and the first mold moving beam 21 is mounted on the first mounting part 111 and the second mounting part 112.
[0028] The technical solution of this utility model adopts a mold-moving beam assembly 2. In the first working state, the first mold-moving beam 21 is installed on the first mounting part 111, and the second mold-moving beam 22 is installed on the second mounting part 112, so that the mold-moving stroke of the mold-moving beam assembly 2 is the sum of the lengths of the first mold-moving beam 21 and the second mold-moving beam 22. In the second working state, the second mold-moving beam 22 is separated from the base 1, and the first mold-moving beam 21 is installed on the first mounting part 111 and the second mounting part 112, so that the mold-moving stroke of the mold-moving beam assembly 2 is the sum of the lengths of the first mold-moving beam 21. The user can adjust the positions of the first mold-moving beam 21 and the second mold-moving beam 22 according to different working conditions, which reduces the labor intensity of the user when switching different mold-moving strokes of the mold-moving device. In this way, two different mold-moving strokes can be provided under the same mold-moving device to adapt to the removal and positioning process of different production molds, thereby reducing production costs.
[0029] In this embodiment, the base 1 may include a first sidewall and a second sidewall disposed opposite to each other. Both the first and second sidewalls have mounting positions 11. Each mounting position 11 is provided with a first mounting portion 111 and a second mounting portion 112. The first mounting portion 111 and the second mounting portion 112 may be configured as sliding grooves or mounting grooves, thereby facilitating the installation of the mold-moving beam assembly 2. To enable more stable movement of the mold on the mold-moving device, the mold-moving device also includes at least two mold-moving beam assemblies 2. At least two mold-moving beam assemblies 2 are detachably mounted on each mounting position 11, allowing the mold to slide on the mold-moving beam assembly 2. To facilitate adjustment of the length of the mold-moving beam assembly 2, the mold-moving beam assembly 2 includes a first mold-moving beam 21 and a second mold-moving beam 22 that are detachably disposed from the base 1. The mold-moving beam assembly 2 is used in a first working state to adjust its length to accommodate molds requiring a long mold-moving stroke for part removal by installing at least a portion of the first mold-moving beam 21 on the first mounting portion 111 and the second mold-moving beam 22 on the second mounting portion 112. The first and second mold-moving beams 21 and 22 are respectively arranged along a first direction. In a second working state, the mold-moving beam assembly 2 is used to adjust its length to accommodate molds requiring a short mold-moving stroke for part removal by detaching the second mold-moving beam 22 from the base 1 and sliding the first mold-moving beam 21 along the first direction from the first mounting portion 111 to the second mounting portion 112. The first mold-moving beam 21 is fastened to both the first and second mounting portions 111 and is arranged along the first direction. This application adjusts the length of the mold-moving beam assembly 2 according to the production mold with different mold-moving strokes, thereby adjusting the length of the mold-moving stroke provided by the mold-moving beam assembly 2 to adapt to production molds with different mold-moving strokes. This simplifies the operation steps of switching the mold-moving device to different working states to provide different mold-moving strokes, thereby reducing production costs.
[0030] like Figure 1 As shown, in one embodiment, the length of the first mold-moving beam 21 along the first direction is greater than the length of the second mold-moving beam 22 along the first direction.
[0031] In this embodiment, in order to more conveniently switch the mold-shifting beam assembly 2 from the first working state to the second working state, this application adopts a second mold-shifting beam 22 with a length smaller than the first mold-shifting beam 21. After the second mold-shifting beam 22 is removed from the base 1, the first mold-shifting beam 21 can quickly slide from the first mounting part 111 to the second mounting part 112 and be installed in the first mounting part 111 and the second mounting part 112. The first mold-shifting beam 21 can quickly fill the installation space of the first mounting part 111 and the second mounting part 112, thereby improving the switching efficiency of the mold-shifting beam assembly 2 when switching between different mold-shifting strokes.
[0032] like Figures 1 to 4 As shown, in one embodiment, the mold transfer device further includes a flip-up side plate 3 disposed on both sides of the base 1. The flip-up side plate 3 has a working state for the mold to slide along the second direction and a storage state for rotating to one side of the base 1, wherein the first direction intersects the second direction.
[0033] In this embodiment, sliding portions can be provided on both sides of the multi-layer mold to be removed. When the flip side plate 3 is in working state, the multi-layer mold can collide with the flip side plate 3 through the sliding portions. Driven by the flip side plate 3, the upper part of the multi-layer mold can be flipped to open the multi-layer mold, thereby facilitating the removal and removal of parts from the multi-layer mold. When the flip side plate 3 is in the storage state, it can avoid obstructing the movement of other types of molds. In order for the mold moving device to open the multi-layer mold more stably, flip side plates 3 can be provided on both sides of the base 1.
[0034] like Figure 3 and Figure 4 As shown, in one embodiment, the mold moving device further includes a connector 4 and a first rotating shaft 5. The connector 4 is mounted on the base 1. The flip side plate 3 includes a connecting section 31, which is detachably mounted on the connector 4. The first rotating shaft 5 passes through the connector 4 and the connecting section 31 in sequence.
[0035] In this embodiment, to facilitate switching the flip side panel 3 between the working state and the storage state, the connector 4 is detachably mounted to the base 1 via fasteners, and the connecting segment 31 is detachably mounted to the connector 4 via fasteners. Both the connector 4 and the connecting segment 31 have third mounting holes. The first rotating shaft 5 passes through the third mounting holes on the connector 4 and the connecting segment 31 respectively, so that the flip side panel 3 can be flipped to the storage state after being detached from the connector 4. Fasteners can be bolts, screws, or studs. The working principle of switching the flip side panel 3 from the working state to the storage state is as follows: the user removes the fasteners from the connecting segment 31 and the connector 4, so that the flip side panel 3 is rotatably connected to the connector 4 via the first rotating shaft 5, and flips the flip side panel 3 to the storage state.
[0036] like Figures 1 to 4 As shown, in one embodiment, the flip side plate 3 includes a sliding section 32 connected to the connecting section 31. The sliding section 32 has an arc-shaped groove 321 on the side away from the connecting section 31. The groove 321 extends along the second direction and is used for sliding engagement of the mold.
[0037] In this embodiment, to facilitate the flipping of the side plate 3 to open the multi-layer mold, the sliding section 32 has an arc-shaped groove 321 on the side away from the connecting section 31. This allows the sliding part of the multi-layer mold to move along the arc-shaped groove 321 during sliding, thereby causing the upper part of the multi-layer mold to flip and open. The multi-layer mold can slide on the mold moving beam assembly 2 along the second mold moving beam 22 toward the first mold moving beam 21. The groove 321 can be provided on the side of the sliding section 32 away from the first mold moving beam 21, thus facilitating the sliding engagement of the sliding part with the groove 321 during sliding.
[0038] like Figure 1 As shown, in one embodiment, the mold moving device further includes a plurality of first rollers 6 and a plurality of second rollers 61. The plurality of first rollers 6 are disposed on the first mold moving beam 21 and are arranged along the first direction. The plurality of second rollers 61 are disposed on the second mold moving beam 22 and are arranged along the first direction.
[0039] In this embodiment, to facilitate the sliding of the mold on the mold-moving beam assembly 2, the mold-moving device further includes multiple first rollers 6 and multiple second rollers 61. The multiple first rollers 6 are disposed on the first mold-moving beam 21, and the multiple second rollers 61 are disposed on the second mold-moving beam 22. The multiple first rollers 6 and multiple second rollers 61 are respectively arranged along a first direction. By employing the first rollers 6 and second rollers 61 to slide with the mold, the mold-moving beam assembly 2 reduces the friction between the mold and the mold-moving beam assembly 2, preventing damage to the mold during sliding.
[0040] like Figure 1 As shown, in one embodiment, the mold moving device further includes a second rotating shaft 7 and a second mounting base 8, wherein the second rotating shaft 7 is mounted on one end of the first mold moving beam 21 away from the second mold moving beam 22 via the second mounting base 8.
[0041] In this embodiment, the two sides of the second rotating shaft 7 are rotatably disposed at the first mold moving beam 21 via the second mounting base 8. The second rotating shaft 7 is used to abut against the bottom of the mold when the mold moving beam assembly 2 moves the mold to the designated mounting position 11. The second rotating shaft 7 can reduce the friction between the second rotating shaft 7 and the mold by rotating, which facilitates the positioning of the mold on the mold moving beam assembly 2.
[0042] like Figure 1 and Figure 4 As shown, in one embodiment, the mold moving device further includes a limiting block 9 for restricting mold movement. The limiting block 9 is disposed on the first mold moving beam 21, and the limiting block 9 is located at one end of the first mold moving beam 21 near the second mold moving beam 22.
[0043] In this embodiment, the limiting block 9 is installed above the first mold-moving beam 21. The limiting block 9 is used to mechanically limit the mold when it moves on the mold-moving beam assembly 2, making it easier to position the mold when it moves on the mold-moving beam assembly 2. By installing the limiting block 9 on the first mold-moving beam 21, this application allows the limiting block 9 to adjust its position according to the position switching of the first mold-moving beam 21, thereby facilitating the limiting block 9 to restrict the position of the mold when the mold-moving beam assembly 2 is in the first working state and the second working state.
[0044] like Figure 2 As shown, in one embodiment, the base 1 has a plurality of first mounting holes 113 arranged along the first direction, and the mold moving beam assembly 2 has a plurality of second mounting holes (not shown). The first mold moving beam 21 is provided through the second mounting holes and the first mounting holes 113 by fasteners, so that the first mold moving beam 21 can be detachably mounted on the first mounting part 111. The second mold moving beam 22 is provided through the second mounting holes and the first mounting holes 113 by fasteners, so that the second mold moving beam 22 can be detachably mounted on the second mounting part 112.
[0045] In this embodiment, to facilitate the installation and disassembly of the first mold-moving beam 21, the first mold-moving beam 21 is fastened to the first mounting part 111 by fasteners passing through the second mounting hole and the first mounting hole 113, or the first mold-moving beam 21 is fastened to the first mounting part 111 and the second mounting part 112. To facilitate the installation and disassembly of the second mold-moving beam 22, the second mold-moving beam 22 is fastened to the second mounting part 112 by fasteners passing through the second mounting hole and the first mounting hole 113, thereby improving the working efficiency of the mold-moving beam assembly 2 in switching between the first working state and the second working state. Fasteners can be bolts, screws, or studs.
