The lower die 10 and the formed weight are transferred along the motorized guide rail 14 to above the ejector 20, and the ejector 20 ejects the weight from the lower die 10. Lifting gripping arms 310 grip and place the demolded weight from lower mold 10 onto a conveyor. The transfer device transfers the weight to the storage area. The production automation of the counterweight is realized, and the production efficiency of the counterweight is improved.
Further, the weight production device further comprises a feeding device for pouring raw materials into the lower die 10, wherein the feeding device is positioned on one side of the lower die 10 and comprises a raw material storage barrel and an oil cylinder ejector rod for driving the raw material storage barrel to rotate around a shaft. The cylinder ejector rod ejects the raw material storage barrel to enable the raw material storage barrel to rotate around the shaft, and raw materials in the raw material storage barrel are poured into the lower die 10 under the action of gravity.
Further, the electric rail 14 is provided with a plurality of lower molds 10. After the raw material in one lower die 10 is pressed by the press 11, the lower die 10 is driven by the electric rail 14 to above the ejector 20, and the next lower die 10 is driven by the electric rail 14 to below the press 11.
Referring to fig. 2, further, the stripper 20 includes a supporter 210, a first elevating driver 220 and a movable plate 230, wherein the supporter 210 is provided with at least one guide bar 250, the first elevating driver 220 is positioned in the supporter 210, the movable plate 230 is provided with a plurality of stripper bars 240 having equal lengths on an upper surface thereof, the guide bar 250 passes through the movable plate 230, the movable plate 230 is positioned above the first elevating driver 220, and the first elevating driver 220 drives the movable plate 230 to perform elevating movement along the guide bar 250. The ejector 20 lifts the weight to separate the weight from the lower die 10, and 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 identical-length ejector rods 240 on the movable plate 230 support the weight and lift the weight. The first elevation driver 220 then drives the movable plate 230 to descend along the guide bar 250, resetting the movable plate 230. The weight is jacked up by the stripper 20, so that the stripping difficulty of the weight is greatly reduced, and the production efficiency of the weight is improved.
Further, the highest end of the guide bar 250 is lower than the highest end of the bracket 210, and the first elevation driver 220 can drive the movable plate 230 to rise to the highest end position of the guide bar 250, which prevents the movable plate 230 from being separated from the bracket 210. The two guide rods 250 are positioned at two sides of the movable plate 230, so that the lifting process of the movable plate 230 is smoother. The number of the stripper bars 240 is four, and the four stripper bars 240 are uniformly disposed around the center of the movable plate 230. This makes the supporting force of the four ejector pins 240 to the weight in the mold more uniform. Specifically, the lifting driver is an oil cylinder ejector rod or a hydraulic ejector rod. In addition, since the weight of the weight member is large, the stripper rod 240 is made of a cemented carbide material, improving durability of the stripper rod 240.

The four stripper bars 240 of the stripper 20 bear against the lower surface of the base plate 120, causing the base plate 120 to move upward in a vertical direction relative to the mold housing 110 until the weight is completely removed from the weight-forming cavity 160. The base plate 120 is then reset by the ejector 20 to continue the weight press molding process for the next round. The bottom plate 120 is not deviated during the lifting by the cooperation of the guide protrusions 142 and the guide grooves 141.
In this embodiment, the weight to be formed is flat cylindrical, and accordingly, the weight forming cavity 160 is cylindrical. In other embodiments, the shape of the weight forming cavity 160 is determined by the weight shape that is actually produced.
Further, the upper surface of the base plate 120 is provided with a boss 130, the base plate 120 is provided with a through hole 131 penetrating the boss 130, and the through hole 131 is inserted with a vertical rod 150.

Referring to fig. 4, further, the elevation gripping arm 310 of the weight handling apparatus 3 includes a second elevation driver 311 and a gripper 312 for gripping the weight, and the second elevation driver 311 drives the gripper 312 to move up and down in the vertical direction. The conveying device comprises a horizontal conveying belt 320, wherein the horizontal conveying belt 320 comprises two transmission chains 321 which are arranged in parallel, a motor 322 for driving the two transmission chains 321 to rotate and a bearing plate 323 positioned on the two transmission chains 321, and the lifting gripping arm 310 can pass through the space between the two transmission chains 321. The conveying device further comprises a counterweight lifting mechanism 330 positioned at the tail end of the conveying direction of the horizontal conveying belt 320, wherein the counterweight lifting mechanism 330 comprises a guide rod 331, a bearing table 333 and a bearing table lifting part 332, the guide rod 331 extends along the vertical direction, the bearing table 333 is in sliding connection with the guide rod 331, the bearing table 333 is fixedly connected with the bearing table lifting part 332, and the bearing table lifting part 332 drives the bearing table 333 to move up and down along the guide rod 331 along the vertical direction.
The second elevating driver 311 of the elevating gripping arm 310 drives the gripper 312 to descend to the position of the weight to grip the weight, and the second elevating driver 311 drives the gripper 312 to pass between the two transmission chains 321 and to ascend above the transmission chains 321, and the supporting plate 323 is located at the rear side of the second elevating driver 311. The motor 322 of the horizontal conveyor belt 320 drives the two drive chains 321 to rotate, so that the supporting plate 323 on the two drive chains moves forward to the lower part of the counterweight, and the grabber 312 places the counterweight on the supporting plate 323. The motor 322 is again started and drives the two drive chains 321 to rotate again, so that the carrier plate 323 is transported to the end of the drive chains 321. At this time, the weight elevating mechanism 330 is raised to the level of the end of the drive chain 321, and the carrier plate 323 is transferred to the weight elevating mechanism 330. The weight lifting mechanism 330 vertically conveys the support plate 323 and the weight thereon downwards to a position which is at the height of the waist of the human body and is close to the weight placement position, thereby facilitating the transportation of the weight to the weight placement position by workers, and enabling the procedure of transporting the weight to be faster and more convenient, time-saving and labor-saving.
Further, the gripper 312 is a suction cup, which is connected to the cylinder through an air pipe. The counterweight is grabbed by the suction force of the sucker. In other embodiments, gripper 312 may also be an electromagnet that is energized to create a magnetic force and is not energized to remove the magnetic force, as typically the mating member is made of a ferrous material.
In addition, the second elevation driver 311 may be an elevation screw.
Further, two ends of the two transmission chains 321 are linked through a linkage piece, the linkage piece comprises a linkage rod and gears positioned at two ends of the linkage rod, the gears are matched with the transmission chains 321, and a motor 322 drives the linkage piece at one end of the transmission chains 321 to rotate. Two parallel transmission chains 321 can be driven to synchronously rotate by one motor 322 through the linkage piece, so that energy is saved, and the other two parallel transmission chains 321 synchronously rotate to enable the transmission bearing plate 323 to be more stable.
Further, the horizontal transfer belt 320 and the weight elevating mechanism 330 constitute a set of weight transfer paths, which have a plurality of sets. The multiple counterweight transmission paths can simultaneously transmit multiple counterweights, and conveying efficiency is improved.
