[0029] Reference Figure 1 One embodiment of the present invention provides a counterweight production device, including a frame 1, a counterweight molding device 2, a demolding device 20 and a counterweight conveying device 3.

[0030] The counterweight forming device 2 includes a press 11 and a counterweight mold; the counterweight mold includes an upper mold 12 and a lower mold 10 that cooperate with each other, the upper mold 12 is connected to the press 11, and the press 11 presses the upper mold 12 to the lower mold 10 to mold the raw material into a counterweight, and the frame 1 is provided with an electric guide rail 14, and the lower mold 10 is placed on the electric guide rail 14;

[0031] The demoulding device 20 is used to demould the counterweight from the lower mold 10, and the demoulding device 20 is located below the electric guide rail 14;

[0032] The counterweight transport device 3 includes a lifting and lowering gripping arm 310 for grabbing the counterweight from the lower mold 10 and a conveying device for conveying the counterweight.

[0033] In this embodiment, the raw material is poured into the lower mold 10, the press 11 drives the upper mold 12 to press the lower mold 10, and the raw material is molded into a counterweight, and the press 11 and the upper mold 12 are reset. The lower mold 10 and the molded counterweight are transferred to the top of the demoulder 20 along the electric guide rail 14; the demoulder 20 demoulds the counterweight from the lower mold 10. The lifting grab arm 310 grabs the demoulded counterweight from the lower mold 10 and places it on the transmission device. The transmission device transfers the counterweight to the storage area. The automation of counterweight production is realized, and the production efficiency of counterweight is improved.

[0034] Furthermore, the counterweight production device also includes a feeding device for pouring raw materials into the lower mold 10. The feeding device is located on one side of the lower mold 10. The feeding device includes a raw material storage barrel and a cylinder top rod driving the raw material storage barrel to rotate around an axis. The cylinder top rod lifts the raw material storage barrel to rotate the raw material storage barrel around an axis, and the raw materials in the raw material storage barrel are poured into the lower mold 10 under the action of gravity.

[0035] Furthermore, a plurality of lower molds 10 are arranged on the electric guide rail 14. After the raw material in a lower mold 10 is pressed and formed by the press 11, the lower mold 10 is driven by the electric guide rail 14 to the top of the demoulder 20; and the next lower mold 10 is driven by the electric guide rail 14 to the bottom of the press 11.

[0036] Reference Figure 2Further, the demoulder 20 includes a bracket 210, a first lifting driver 220 and a movable plate 230; the bracket 210 is provided with at least one guide rod 250; the first lifting driver 220 is located in the bracket 210; a plurality of demoulding rods 240 of equal length are provided on the upper surface of the movable plate 230, the guide rod 250 passes through the movable plate 230, and the movable plate 230 is located above the first lifting driver 220; the first lifting driver 220 drives the movable plate 230 to move up and down along the guide rod 250. The demoulder 20 lifts the counterweight to separate the counterweight from the lower mold 10; in this process, the first lifting driver 220 drives the movable plate 230 to rise along the guide rod 250, so that the plurality of demoulding rods 240 of equal length on the movable plate 230 support the counterweight and lift the counterweight. Then the first lifting driver 220 drives the movable plate 230 to descend along the guide rod 250, so that the movable plate 230 is reset. The counterweight is lifted up by the demoulding device 20, which greatly reduces the difficulty of demoulding the counterweight and improves the production efficiency of the counterweight.

[0037] Further, the highest end of the guide rod 250 is lower than the highest end of the bracket 210, and the first lifting driver 220 can drive the movable plate 230 to rise to the highest end position of the guide rod 250, so that the movable plate 230 will not separate from the bracket 210. There are two guide rods 250, and the two guide rods 250 are located on both sides of the movable plate 230, so that the lifting process of the movable plate 230 is smoother. There are four demoulding rods 240, and the four demoulding rods 240 are evenly arranged around the center of the movable plate 230. This makes the supporting force of the four demoulding rods 240 on the counterweight in the mold body more uniform. Specifically, the lifting driver is a cylinder push rod or a hydraulic push rod. In addition, due to the large weight of the counterweight, the demoulding rod 240 is made of a hard alloy material to improve the durability of the demoulding rod 240.

[0038] In addition, the plate of the upper supporting portion of the electric guide rail 14 of the demoulding device 20 is provided with a hole for the demoulding rod 240 to pass through.

[0039] Reference Figure 2 and Figure 3Further, the lower mold 10 includes a mold shell 110 and a bottom plate 120; the mold shell 110 is provided with a counterweight molding cavity 160; the bottom plate 120 is located in the counterweight molding cavity 160 and can move up and down in the vertical direction relative to the mold shell 110. Specifically, the cavity wall of the counterweight molding cavity 160 is provided with a guide protrusion 142 extending in the vertical direction, and the outer edge of the bottom plate 120 is provided with a guide groove 141; the guide protrusion 142 is located in the guide groove 141, and the bottom plate 120 moves along the guide protrusion 142. The four demolding rods 240 of the demolding device 20 are pressed against the lower surface of the bottom plate 120, so that the bottom plate 120 moves upward in the vertical direction relative to the mold shell 110 until the counterweight is completely separated from the counterweight molding cavity 160. Then, under the action of the demolding device 20, the bottom plate 120 is reset to continue the next round of the counterweight molding process. The cooperation between the guide protrusion 142 and the guide groove 141 prevents the bottom plate 120 from deflecting during the lifting process.

[0040] It should be noted that in this embodiment, the counterweight to be formed is a flat cylindrical shape, and accordingly, the counterweight forming cavity 160 is cylindrical. In other embodiments, the shape of the counterweight forming cavity 160 is determined by the shape of the counterweight actually produced.

[0041] Furthermore, a boss 130 is provided on the upper surface of the bottom plate 120, and a through hole 131 is provided on the bottom plate 120 to penetrate the boss 130, and a vertical rod 150 is inserted into the through hole 131. The formed counterweight is formed with a groove corresponding to the position of the boss 130 and a through hole corresponding to the position of the vertical rod 150.

[0042] Reference Figure 4 Further, the lifting grab arm 310 of the counterweight transport device 3 includes a second lifting driver 311 and a grabber 312 for grabbing the counterweight, and the second lifting driver 311 drives the grabber 312 to move up and down in the vertical direction. The transmission device includes a horizontal transmission belt 320, and the horizontal transmission belt 320 includes two parallel transmission chains 321, a motor 322 for driving the two transmission chains 321 to rotate, and a supporting plate 323 located on the two transmission chains 321, and the lifting grab arm 310 can pass through the two transmission chains 321. The transmission device also includes a counterweight lifting mechanism 330 located at the end of the horizontal conveyor belt 320 in the transmission direction; the counterweight lifting mechanism 330 includes a guide rod 331, a load-bearing platform 333 and a load-bearing platform lifting part 332; the guide rod 331 extends in the vertical direction; the load-bearing platform 333 is slidably connected to the guide rod 331, the load-bearing platform 333 is fixedly connected to the load-bearing platform lifting part 332, and the load-bearing platform lifting part 332 drives the load-bearing platform 333 to move up and down in the vertical direction along the guide rod 331.

[0043] The second lifting driver 311 of the lifting grab arm 310 drives the grabber 312 to descend to the position of the counterweight and grab the counterweight; the second lifting driver 311 drives the grabber 312 to pass between the two transmission chains 321 and rise to the top of the transmission chains 321, and at this time, the supporting plate 323 is located at the rear side of the second lifting driver 311. The motor 322 of the horizontal conveyor belt 320 drives the two transmission chains 321 to rotate, so that the supporting plate 323 on them moves forward to the bottom of the counterweight, and the grabber 312 puts the counterweight on the supporting plate 323. The motor 322 is started again and drives the two transmission chains 321 to rotate again, so that the supporting plate 323 is transported to the end of the transmission chain 321. At this time, the counterweight lifting mechanism 330 rises to the horizontal height of the end of the transmission chain 321, and the supporting plate 323 is transferred to the counterweight lifting mechanism 330. The counterweight lifting mechanism 330 transports the support plate 323 and the counterweight thereon vertically downward to a position at the waist height of the human body and close to the counterweight placement position; this facilitates workers to carry the counterweight to the counterweight placement position; and makes the process of carrying the counterweight faster and more convenient, saving time and effort.

[0044] Furthermore, the gripper 312 is a suction cup connected to the cylinder through an air pipe. The counterweight is gripped by the suction of the suction cup. In other embodiments, since the counterweight is usually made of steel, the gripper 312 can also be an electromagnet that generates magnetic force when powered on and has no magnetic force when powered off.

[0045] In addition, the second lifting driver 311 may be a lifting screw.

[0046] Furthermore, both ends of the two transmission chains 321 are linked by a linkage member; the linkage member includes a linkage rod and gears at both ends of the linkage rod, and the gears cooperate with the transmission chain 321; the motor 322 drives the linkage member at one end of the transmission chain 321 to rotate. Through the linkage member, one motor 322 can drive two parallel transmission chains 321 to rotate synchronously, saving energy; the other two parallel transmission chains 321 rotate synchronously to make the transmission support plate 323 more stable.

[0047] Furthermore, the horizontal conveyor belt 320 and the counterweight lifting mechanism 330 form a set of counterweight transmission paths; there are multiple sets of counterweight transmission paths. Multiple sets of counterweight transmission paths can simultaneously transmit multiple counterweights, thereby improving handling efficiency.

[0048] Further, in other embodiments, the lifting grab arm 310 is connected to a transverse electric guide rail (not shown) and can move along the transverse electric guide rail above the beginning of the multiple groups of counterweight transmission paths. The multiple groups of counterweight transmission paths include at least one first transmission path for transmitting qualified counterweights and at least one second transmission path for transmitting failed counterweights. Before entering the counterweight handling process, a counterweight process can be provided. In the counterweight process, the counterweight is tested by a counterweight quality detection instrument to distinguish the counterweight as a qualified counterweight or a failed counterweight. The lifting grab arm 310 grabs the counterweight. According to the detection result of the counterweight quality detection instrument, if the counterweight is a qualified product, the lifting grab arm 310 places the counterweight on the first transmission path for transmitting qualified counterweights; if the counterweight is a failed product, the lifting grab arm 310 places the counterweight on the second transmission path for transmitting failed counterweights.

[0049] The above is only a preferred embodiment of the present invention. The present invention is not limited to the above implementation mode. As long as the technical effect of the present invention is achieved by the same means, it should belong to the protection scope of the present invention.
