Description

Technical Field

[0001] This utility model relates to the field of mold changing trolley technology, and in particular to a lifting double-layer mold changing trolley. Background Technology

[0002] In existing technology, a mold-changing carriage generally includes a carriage with a support frame, and a mold-changing assembly mounted on the support frame. The mold-changing assembly is used to remove the mold from the injection molding machine and transport the new mold from the carriage to the injection molding machine. Existing mold-changing carriages typically have two stations on their platform. One station is used to hold the mold to be transported to the injection molding machine, and the other station is used to hold the mold removed from the injection molding machine. Because this platform has two stations, both located on the same platform, the overall platform length is relatively long. Furthermore, during use, the platform needs to be moved laterally to align the different stations with the injection molding machine. These factors necessitate leaving a relatively large lateral space on one side of the injection molding machine for these operations. However, sometimes the lateral space on the injection molding machine side is limited, making this type of mold-changing carriage inconvenient to use. Utility Model Content

[0003] Based on this, a lifting double-layer mold-changing trolley is provided. This trolley requires relatively little lateral space during use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lifting double-layer mold-changing trolley includes a mobile trolley with a support frame. A base is mounted on the support frame, and a lifting mechanism is mounted on the base. A frame is connected to the lifting mechanism, which drives the frame to move up and down. The frame includes an upper platform and a lower platform spaced apart, with a storage space between them. Conveying components are mounted on both the lower and upper platforms. Each conveying component includes a central chain track and load-bearing rollers located on either side of the central chain track.

[0006] A first chain track is provided on one side of the top of the bracket, and a second chain track is provided on the other side of the top of the bracket. A hook is provided at the first chain track, and a push-pull assembly connected to the bracket is provided on one side of the hook. The push-pull assembly is connected to the hook.

[0007] The intermediate chain track is used to connect and cooperate with the first chain track and the second chain track.

[0008] In one embodiment, the lifting mechanism includes a screw jack.

[0009] In one embodiment, there are two sets of screw jacks, which are spaced apart. Each set of screw jacks includes two screw jacks connected in series, and each set of screw jacks is connected to a motor drive assembly.

[0010] In one embodiment, blocking cylinders are provided on one side of the upper platform and one side of the lower platform.

[0011] In one embodiment, a rear limit stop is provided on one side of each of the Shangcen platforms and on one side of the lower platform.

[0012] In one embodiment, a plurality of guide rollers are arranged at intervals on the upper platform outside the bearing roller conveyor.

[0013] In one embodiment, a plurality of guide rollers are arranged at intervals on the lower platform outside the bearing roller conveyor.

[0014] In one embodiment, the mobile trolley is a pallet truck, and the bracket is mounted on the forks of the pallet truck.

[0015] In one embodiment, a housing connected to the support is also included, which encloses the support.

[0016] In one embodiment, the extension direction of the intermediate chain track is consistent with the length direction of the moving trolley.

[0017] The beneficial effects of this application are as follows:

[0018] This application makes full use of vertical space by setting up an upper platform and a lower platform on the trolley. The upper platform has only one station, unlike the two stations in existing technologies, thus reducing the lateral length. Furthermore, since there is only one station, there is no need for lateral movement to switch stations as in existing technologies, further reducing the required lateral space. The lower platform of this application is located below the upper platform, and the upper and lower platforms are switched via a lifting mechanism, thus making full use of vertical space for mold changing operations. The mold changing trolley of this application can be used on one side of an injection molding machine with limited lateral space. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 and Figure 2As shown, an embodiment of this application provides a lifting double-layer mold-changing trolley, which includes a mobile trolley 110, a support 120 on the mobile trolley 110, a base 121 on the support 120, a lifting mechanism 130 on the base 121, and a frame 140 connected to the lifting mechanism 130. The lifting mechanism 130 is used to drive the frame 140 to move up and down. The frame 140 includes an upper platform 141 and a lower platform 142 spaced apart, with a storage space between the upper platform 141 and the lower platform 142. The lower platform 142 and the upper platform... Each of the 141 is equipped with a conveying assembly, which includes an intermediate chain track 152 and bearing rollers 154 located on both sides of the intermediate chain track 152. A first chain track 151 is provided on one side of the top of the support 120, and a second chain track 153 is provided on the other side of the top of the support 120. A hook 161 is provided at the first chain track 151, and a push-pull assembly 162 connected to the support 120 is provided on one side of the hook 161. The push-pull assembly 162 is connected to the hook 161. The intermediate chain track 152 is used to dock and cooperate with the first chain track 151 and the second chain track 153.

[0031] When a mold change is required, the mold 200 of the injection molding machine 300 can be pulled out via the hook 161 driven by the push-pull assembly 162 and placed on the upper platform 141. Then, the lower platform 142 is raised via the lifting mechanism 130, and the mold 200 on the lower platform 142 is conveyed into the injection molding machine 300 via the hook 161 driven by the push-pull assembly 162. Next, the lower platform 142 is lowered and reset via the lifting mechanism 130.

[0032] Specifically, the hook 161 and the corresponding push-pull assembly 162 are both existing technologies. In the prior art, a release cylinder can also be provided at the hook 161 to assist in separating the hook 161 from the mold 200. The push-pull assembly 162 generally includes a motor, a transmission assembly, and a chain. The hook 161 can move along the first chain track 151, the intermediate chain track 152, and the second chain track 153.

[0033] To further reduce the required lateral space, such as Figure 2 and Figure 6 As shown, in one embodiment, the extension direction of the intermediate chain track 152 is consistent with the length direction of the moving trolley 110. This arrangement can effectively reduce the lateral space required during mold changing.

[0034] In one embodiment, the lifting mechanism 130 includes a screw jack 131. The lifting portion of the screw jack 131 is connected to the bottom of the frame 140. For example, as Figure 3 and Figure 4 As shown, there are two sets of screw jacks 131, spaced apart. Each set of screw jacks 131 includes two screw jacks connected in series, and each set is connected to a motor drive assembly 132. One motor drive assembly 132 simultaneously drives the two screw jacks 131 connected in series to move synchronously. The frame 140 is raised and lowered via each screw jack 131.

[0035] Based on the above, in one embodiment, a blocking cylinder 171 is provided on one side of the upper platform 141 and one side of the lower platform 142. When the mold 200 is positioned on the platform, the piston rod of the blocking cylinder 171 rises to block the mold 200. It is understood that after the piston rod of the blocking cylinder 171 descends, the mold 200 is no longer blocked by the piston rod of the blocking cylinder 171 and can move.

[0036] In one embodiment, a rear limit stop 172 is provided on one side of the upper platform 141 and one side of the lower platform 142.

[0037] Specifically, the rear limit stop 172 and the aforementioned blocking cylinder 171 are located on opposite sides of the platform. The rear limit stop 172 is used to limit the mold 200 pulled into the platform. For example, when the hook 161 pulls the mold 200 into the platform, the mold 200 can no longer move after it abuts against the rear limit stop 172.

[0038] In one embodiment, a plurality of guide rollers 173 are arranged at intervals on the upper platform 141 outside the bearing roller conveyor 154. For example... Figure 3 As shown, the guide roller 173 has two rows, with four rollers in each row.

[0039] Specifically, the aforementioned guide roller 173 is used to ensure that the mold 200 is aligned after entering the platform.

[0040] Similarly, a number of guide rollers 173 are arranged at intervals on the lower platform 142 outside the bearing roller conveyor 154.

[0041] In one embodiment, the mobile trolley 110 is a pallet transporter, and the bracket 120 is mounted on the pallet transporter's forks 111. The pallet transporter is a conventional trolley. This trolley has forks 111. The bracket 120 can be fixed to the forks 111.

[0042] In one embodiment, a housing 180 connected to the bracket 120 is also included, the housing 180 enclosing the bracket 120. The housing 180 can be connected to the bracket 120 by screws. Alternatively, the housing 180 can be connected to the bracket 120 by other means. The housing 180 may have corresponding through holes. For example, if the screw jack 131 is connected to a motor drive assembly 132, and the motor drive assembly 132 is located outside the bracket 120, then the housing 180 may have through holes through which the motor drive assembly 132 passes.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
