[0005] For this reason, an extrusion molding device for a stainless steel material tray is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides an extrusion molding device for a stainless steel material tray to solve the problem of troublesome lower mold replacement.

[0011] Furthermore, a second hydraulic cylinder is provided at the bottom of the device base, and a top plate is fixedly installed at the telescopic end of the second hydraulic cylinder. The top plate is arranged inside the mold base and below the lower mold.

[0014] Furthermore, a third hydraulic cylinder is provided on the top of the collecting box, and a pressure plate is fixedly installed on the telescopic end of the third hydraulic cylinder.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model can allow the lower mold to be fixedly installed in the mold seat through the limit assembly. When the lower mold needs to be disassembled, the rotating rod is driven to rotate by turning the rotating knob. Under the interaction of the two sections of external threads of the rotating rod and the internal threads of the two movable plates, the two movable plates can move inward or outward at the same time, thereby driving the clamping rod to move together. When the clamping rod is clamped in the clamping groove of the mounting plate, the mounting plate can be fixed, thereby installing the lower mold. When the clamping rod is disengaged from the clamping groove of the mounting plate, the fixation of the mounting plate can be released, and then the telescopic end of the second hydraulic cylinder is driven to move outward, so that the top plate pushes the lower mold upward, and the lower mold can be moved out of the mold seat, thereby facilitating the staff to disassemble and assemble the lower mold. Compared with the method of fixing the lower mold with bolts, the present application does not need to spend too much time to replace the lower mold, and replacing the lower mold is also more convenient.

[0017] 2. The utility model can move the lifting frame and the upper mold up and down through the lifting assembly, so that the stainless steel billet can be extruded. Moreover, under the action of the lifting frame and the sliding plate, the lifting frame will drive the sliding plates on both sides to slide on the surface of the guide rod while the upper mold descends, so that the lifting frame can descend more smoothly, avoiding the upper mold from shifting during the descent process, which would cause the stainless steel billet to be incorrectly extruded, thereby reducing the scrap rate of the stainless steel billet.

[0018] 2. The utility model can collect waste chips generated during the processing by the dust suction component, and can suck the waste chips from the dust suction hood into the collection box by driving the fan, which can reduce the number of manual cleaning times and also prevent the waste chips from accidentally entering the eyes, ears or noses of the workers during the processing of the stainless steel tray, thereby improving a certain degree of safety. Moreover, by moving the telescopic end of the third hydraulic cylinder inward and outward, the pressing plate can be moved up and down to press the waste chips into blocks to reduce the volume of the waste chips and facilitate transportation and storage.

[0027] Figure 1 to Figure 6 This is the best embodiment of the utility model, and the following is combined with the accompanying drawings Figure 1 to Figure 6 The utility model is further described.

[0028] A stainless steel material tray extrusion molding device includes a device base 1, and also includes a support frame 2, a lifting frame 3, an upper mold 4, a lifting assembly 5, a mold seat 6, a lower mold 7, a limit assembly 10 and a dust suction assembly 11. The support frame 2 is welded on the top of the device base 1, and the lifting frame 3 is arranged on the inner side of the support frame 2. The upper mold 4 is fixedly installed on the bottom of the lifting frame 3. The lifting assembly 5 is arranged inside the support frame 2. The lifting assembly 5 is connected to the lifting frame 3 and drives the lifting frame 3 to move in a direction close to or away from the device base 1. The mold seat 6 is fixedly installed on the upper surface of the device base 1, and the lower mold 7 and the limit assembly 10 are arranged inside the mold seat 6. The limit assembly 10 allows the lower mold 7 to be connected to the mold seat 6, and the dust suction assembly 11 is arranged on both sides of the left and right sides of the support frame 2.

[0029] A PLC controller is provided on the side of the support frame 2, and the first hydraulic cylinder 501, the second hydraulic cylinder 8, the fan 1103 and the third hydraulic cylinder 1106 are electrically connected to the PLC controller. The PLC controller can control the switching of the first hydraulic cylinder 501, the second hydraulic cylinder 8, the fan 1103 and the third hydraulic cylinder 1106 respectively.

[0030] Specifically, the limit assembly 10 includes a mounting groove 1001, and mounting grooves 1001 are provided on both sides of the mold base 6, and mounting plates 1002 are fixedly installed on both sides of the left and right sides of the lower mold 7. A bearing seat 1003 is fixedly installed inside the mold base 6, and a rotating rod 1004 is rotatably connected inside the bearing seat 1003. A rotating knob 1005 is fixedly connected to the side of the rotating rod 1004. A movable plate 1006 is threadedly connected to the surface of the rotating rod 1004, and a clamping rod 1007 is fixedly installed on the side of the movable plate 1006. A clamping groove 1008 is provided on the side of the mounting plate 1002, and the clamping rod 1007 is adapted to the clamping groove 1008.

[0031] The surface of the rotating rod 1004 is provided with two opposite external threads. There are two movable plates 1006 . The interiors of the two movable plates 1006 are both provided with internal threads, and the internal threads of the two movable plates 1006 match the two external threads of the rotating rod 1004 .

[0032] In this embodiment, by placing the lower mold 7 in the mold base 6, the mounting plate 1002 can be placed in the mounting groove 1001, and then the rotating knob 1005 is rotated to drive the rotating rod 1004 to rotate. Under the interaction of the two sections of external threads of the rotating rod 1004 and the internal threads of the two movable plates 1006, the two movable plates 1006 can move inward or outward at the same time, thereby driving the clamping rod 1007 to move together, so that the clamping rod 1007 is engaged or disengaged from the clamping groove 1008, thereby fixing or splitting the mold base 6 and the lower mold 7.

[0033] Specifically, a limiting rod 1009 is fixedly installed inside the mold base 6 , and the movable plate 1006 is slidably connected to the limiting rod 1009 .

[0034] In this embodiment, the movable plate 1006 can slide on the surface of the limiting rod 1009 and can play a limiting role.

[0035] Specifically, a second hydraulic cylinder 8 is disposed at the bottom of the device base 1 , and a top plate 9 is fixedly mounted on the telescopic end of the second hydraulic cylinder 8 . The top plate 9 is disposed inside the mold base 6 and below the lower mold 7 .

[0036] In this embodiment, the telescopic end of the second hydraulic cylinder 8 is driven to move inward and outward, so that the top plate 9 can move up and down, so that the top plate 9 can push the lower mold 7 upward, and the lower mold 7 can be moved out of the mold base 6.

[0037] Specifically, the lifting assembly 5 includes a first hydraulic cylinder 501, and the first hydraulic cylinder 501 is arranged on the top of the support frame 2, and the lifting frame 3 is fixedly installed on the telescopic end of the first hydraulic cylinder 501, and a slide groove 502 is opened on the inner side of the support frame 2, and a guide rod 503 is fixedly installed inside the slide groove 502, and a sliding plate 504 is slidably connected to the surface of the guide rod 503, and the lifting frame 3 is fixedly installed on the side of the sliding plate 504.

[0038] In this embodiment, the telescopic end of the first hydraulic cylinder 501 is driven to move inward and outward, so that the lifting frame 3 and the upper mold 4 can move up and down, thereby being able to extrude the stainless steel billet. Moreover, when the upper mold 4 descends, the lifting frame 3 will drive the sliding plates 504 on both sides to slide on the surface of the guide rod 503, so that the lifting frame 3 can descend more smoothly, avoiding the upper mold 4 from deflecting during the descent process.

[0039] Specifically, the dust collection component 11 includes a collection box 1101, and the collection boxes 1101 are fixedly installed on the left and right sides of the support frame 2. The sides of the collection box 1101 are fixedly connected to the dust hood 1102 through connecting pipes. A fan 1103 is arranged on the side of the collection box 1101 away from the dust hood 1102. A filter screen 1104 is fixedly installed inside the collection box 1101, and a collection box 1105 is arranged at the bottom of the collection box 1101.

[0040] In this embodiment, by driving the fan 1103, waste chips can be sucked into the collection box 1101 from the dust hood 1102. The incoming waste chips will be blocked by the filter 1104, so that the waste chips remain in the collection box 1101. Then, the fan 1103 is turned off, and the waste chips will fall without the action of external force, thereby leaving the waste chips in the collection box 1105.

[0041] Specifically, a third hydraulic cylinder 1106 is disposed on the top of the collection box 1101 , and a pressing plate 1107 is fixedly installed on the telescopic end of the third hydraulic cylinder 1106 .

[0042] In this embodiment, the pressing plate 1107 can be moved up and down by moving the telescopic end of the third hydraulic cylinder 1106 inward and outward, and the waste chips can be pressed into blocks to reduce the volume of the waste chips and facilitate transportation and storage.

[0043] The working principle and use process of the utility model are as follows: when it is necessary to process the stainless steel blank, the staff puts the stainless steel blank on the lower mold 7, drives the telescopic end of the first hydraulic cylinder 501 to move inward and outward, and allows the lifting frame 3 and the upper mold 4 to move up and down, so that the stainless steel blank can be extruded. Moreover, when the upper mold 4 descends, the lifting frame 3 will drive the sliding plates 504 on both sides to slide on the surface of the guide rod 503, so that the lifting frame 3 descends more smoothly, avoiding the upper mold 4 from deviating during the descent process, thereby causing the stainless steel blank to be misaligned. When stainless steel trays of different shapes and sizes need to be pressed, different lower molds 7 need to be replaced. The existing lower mold 7 is first removed, and the rotating rod 1004 is driven to rotate by rotating the rotating knob 1005, so that the two movable plates 1006 can move outward at the same time, thereby driving the clamping rod 1007 to move outward together, so that the clamping rod 1007 is separated from the clamping groove 1008. At this time, the mounting plate 1002 will release the limit, and then the telescopic end of the second hydraulic cylinder 8 will be driven to move inward and outward, so that the top plate 9 can be moved upward. By pushing the lower mold 7 upward, the lower mold 7 can be moved out of the mold seat 6, and the staff can easily take out the lower mold 7, and then place the required lower mold 7 in the mold seat 6, and the mounting plate 1002 will also be placed in the mounting groove 1001, and then the rotating knob 1005 is reversed to make the clamping rod 1007 clamped in the clamping groove 1008, so that the mounting plate 1002 can be limited, so that the lower mold 7 is installed. Compared with the method of fixing the lower mold 7 with bolts, the present application does not need to spend too much time to replace the lower mold 7, and the replacement of the lower mold 7 is also more convenient; During the processing of the stainless steel material tray, waste chips will be generated. At this time, the fan 1103 can be driven to suck the waste chips from the dust hood 1102 into the collection box 1101. The incoming waste chips will be blocked by the filter 1104, so that the waste chips remain in the collection box 1101. Then the fan 1103 is turned off, and the waste chips will fall without external force, so that the waste chips will remain in the collection box 1105. Then the telescopic end of the third hydraulic cylinder 1106 is driven to move inward and outward, so that the pressure plate 1107 can be moved up and down, and the waste chips can be pressed into blocks to reduce the volume of the waste chips and facilitate transportation and storage.
