Description

Technical Field

[0001] This utility model belongs to the field of industrial automation production line device design technology, specifically relating to an automatic pitch-changing device for a mold pallet. Background Technology

[0002] Existing automated production lines utilize a multi-station gantry structure for each process, with molds carrying materials passing underneath the gantry. The molds are loaded onto one side of the gantry, processed at the machining station, and then unloaded from the other side. Currently, transfers between processes rely on manual operation. The main function of the pressing line automation project is to replace manual operation with automation, connecting the existing process equipment into an automated production line. During implementation, it was discovered that the spacing between the workstations of the various process equipment is inconsistent, necessitating an automatic spacing adjustment function in the automatic transfer device between the equipment. Therefore, a mold pallet spacing adjustment mechanism needs to be specifically designed to meet this functional requirement through ingenious mechanism design. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic pitch-changing device for mold pallets, which solves the problem of inconsistent station spacing in existing process equipment and meets the pitch-changing function requirements of mold pallets.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic pitch-changing device for a mold tray, wherein the device includes: a mold tray installed on a tray guide rail, the tray guide rail being fixed to the upper part of a mechanism mounting plate, a drive cylinder installed on the lower part of the mechanism mounting plate located on both sides of the device, the cylinder rod end of the drive cylinder being connected to the mold tray located at both ends of the guide rail through a cylinder connecting plate, and the pitch of the mold tray being switched by controlling the extension and retraction of the cylinder rod of the drive cylinder; a short fixed-distance connecting rod and a long fixed-distance connecting rod are provided on the lower surface of the mold tray, and the fixed-distance connecting rod and the mold tray form a hinge structure, which plays a role in regulating the pitch.

[0005] The aforementioned automatic pitch-changing device for a mold tray includes a strip-shaped protrusion on the upper surface of the mold tray. This strip-shaped protrusion can cooperate with the outer surface of the mold to fix the mold on the tray, preventing the mold from detaching from the upper surface of the mold tray and restricting the movement of the mold on the mold tray.

[0006] In the aforementioned automatic pitch-changing device for a mold tray, a slider is provided under the mold tray, and the mold tray moves on the tray guide rail via the slider.

[0007] In the aforementioned automatic pitch-changing device for a mold pallet, the drive cylinder serves as the power component of the entire automatic pitch-changing device, providing power for the pitch change of the mold pallet.

[0008] The aforementioned automatic pitch-changing device for a mold tray includes a cylindrical protrusion at the bottom of the mold tray. The mold tray forms a hinge structure with the cylindrical protrusion and the elongated holes on the short and long fixed-distance connecting rods.

[0009] In the aforementioned automatic pitch-changing device for a mold pallet, when the cylinder rod of the drive cylinder extends, the cylinder moves the mold pallets located at both ends of the pallet guide rail to the far end via the cylinder connecting plate. The short fixed-distance connecting rods on the outside also move in the same direction under the drag of the mold pallets until the cylindrical protrusions of the mold pallets move to the edge of the long hole of the short fixed-distance connecting rod. The long hole acts as a limit, and the long fixed-distance connecting rod performs the same movement. Finally, all the cylindrical protrusions of the mold pallets in the pitch-changing device move to the edge of the long hole, and the automatic pitch-changing device is in the connecting rod extended state.

[0010] In the aforementioned automatic pitch-changing device for a mold pallet, when the cylinder rod of the drive cylinder retracts, the automatic pitch-changing process is the opposite of the extension process of the cylinder rod of the drive cylinder, and finally the automatic pitch-changing device is in the connecting rod retracted state.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The automatic pitch-changing device for a mold tray provided by this utility model, on the one hand, realizes the automatic pitch-changing function of the mold tray through the structural design of the device. On the other hand, the ingenious and simple structural design of the device can ensure the stable realization of the pitch-changing function. Attached Figure Description

[0017] To address the issue of inconsistent station spacing in existing process equipment, this utility model provides an automatic spacing adjustment device for mold trays. For example... Figures 1-4 As shown, the main function of this device is to automatically adjust the pitch of the mold tray between different processes. The automatic pitch-adjusting device includes: a mold tray 101, a tray guide rail 102, a mechanism mounting plate 103, a drive cylinder 201, a short fixed-distance connecting rod 202, and a long fixed-distance connecting rod 203. The mold involved in the process is cylindrical, and the mold tray 101 supports the mold as it completes the pitch-adjusting action on the device. The mold is placed on the mold tray 101, and the upper surface of the mold tray 101 is provided with strip-shaped protrusions. These protrusions can cooperate with the outer surface of the mold to fix the mold on the tray, ensuring that the mold does not detach from the upper surface of the mold tray 101 throughout the pitch-adjusting process and restricting the lateral movement of the mold on the mold tray 101.

[0018] The mold tray 101 is mounted on the tray guide rail 102 via a guide rail slider. The slider is fixed to the lower part of the mold tray 101 with screws, while the tray guide rail 102 is fixed to the mechanism mounting plate 103 with screws. The tray guide rail 102 and the slider at the bottom of the mold tray 101 cooperate to restrict the movement of the mold tray 101 to the direction of the tray guide rail 102, and the sides of the mold tray 101 remain parallel during movement. A columnar protrusion on the lower surface of the mold tray 101, together with the elongated holes on the short fixed-distance connecting rod 202 and the long fixed-distance connecting rod 203, forms a hinge structure. The drive cylinder 201 is mounted on the lower part of the mechanism mounting plate 103 located on both sides of the device and is fastened to the mechanism mounting plate 103 with screws. The cylinder rod end of the drive cylinder 201 is fastened to the mold tray 101 located at both ends of the guide rail via a cylinder connecting plate with screws. The drive cylinder 201 is the power component of the entire device, providing power for the pitch change of the mold tray 101. The spacing of the mold tray 101 can be controlled by extending and retracting the cylinder rod of the drive cylinder 201, thereby achieving automatic switching of the spacing of the mold tray 101.

[0019] When the piston rod of the drive cylinder 201 extends, the mold tray 101 is shifted to the far end. The precise change in spacing is achieved due to the limiting effect of the hinge structure between the mold tray 101 and the short and long fixed-distance connecting rods 202 and 203. Conversely, when the piston rod of the drive cylinder 201 retracts, the mold tray 101 is pulled back to the near end. The precise change in spacing is again achieved through the regulating effect of the hinge structure between the mold tray 101 and the short and long fixed-distance connecting rods 202 and 203. During the extension and retraction of the piston rod of the drive cylinder 201, the elongated holes on the short and long fixed-distance connecting rods 202 and 203 serve as limits for the mold tray 101. The cooperation of the short and long fixed-distance connecting rods 202 and 203 successfully allows for the successful change of different spacings at the hinge points of the mold tray 101. When the cylinder rod of the drive cylinder 201 extends, the mold trays 101 located at both ends of the tray guide rail 102 move to the far end through the cylinder connecting plate. The short fixed-distance connecting rod 202 on the outside also moves in the same direction under the drag of the mold trays 101 until the cylindrical protrusions of the mold trays 101 move to the edge of the long hole of the short fixed-distance connecting rod 202. The long hole acts as a limit, and the movement is transmitted to the long fixed-distance connecting rod 203 in the same way, causing it to move in the same direction. Finally, all the cylindrical protrusions of the mold trays 101 move to the edge of the long hole, and the pitch change is in place. At this time, the automatic pitch change device is in the connecting rod extended state 401. When the cylinder rod of the drive cylinder 201 retracts, the process is the reverse of the above, and the automatic pitch change device is finally in the connecting rod retracted state 402.
