Description

Technical Field

[0001] The present invention relates to the technical field of plastic pressing, in particular to a gun body forming device based on a plastic spray gun. Background Art

[0002] Spray guns are mainly used for spraying workpieces. In order to save costs and promote green development, the materials used in spray guns are recycled materials. The molding process of spray gun shells is mostly through compression molding, and the spray gun shells are mainly made of thermosetting plastics such as phenolic plastics and amino plastics. Because phenolic plastics and amino plastics have high melt viscosity and poor fluidity, they can only be formed through a pressing process.

[0003] For thermoplastics with high melt viscosity and poor fluidity, the recycled waste materials need to be cleaned and crushed before pressing, and then the waste material particles need to be melted and reused. The molten plastic is then weighed and cut into multiple small pieces and placed into a mold connected to multiple stations. The material is filled into multiple stations through pressing, but the multiple workpieces after molding are connected together, so further cutting is required, and the cut surface is very unsightly. The cut waste materials need to be cleaned, crushed and melted again, which affects efficiency and re-melting increases costs. In addition, the material is not uniform during cutting, which easily leads to material shortages in the workpiece. In addition, excessive contact between the outside air and the surface of the material during cutting will cause the surface of the material to harden slightly, and the hardened part will have lines on the surface after stamping, affecting the quality.

[0034] The mobile feeding mechanism 6 is combined with the uniform material distribution mechanism 3 to evenly distribute the input material under heat preservation, and drive the evenly cut material to move in the multi-station bottom mold 21, and cooperate with multiple springs 2 314 to push the material at a speed to add the material to multiple stations in turn, avoiding the hardening of the material surface while evenly feeding the material into multiple stations, realizing multi-station non-connected pressing, and no waste connection between multiple workpieces after pressing, reducing the later cutting steps and the later waste processing steps, improving processing efficiency, and performing heat preservation treatment on the raw materials, and quickly feeding multiple cut raw materials into the station under heat preservation state, reducing the time the raw materials are exposed to the air, and avoiding the unsightly surface of the workpiece caused by hardening of the raw material surface and pressing.

[0035] Working principle: The plastic raw materials and plastic waste are placed in the melter 5 for melting, and then the melted materials are weighed and placed in the interior of the box 35. The pressing program is started by the controller 7. The controller 7 starts the motor 41 to drive the gear 1 42 to reverse. The reversal of the gear 1 42 satisfies the direction of the rotation of the one-way gear 2 317 to drive the reciprocating screw 1 36 to rotate. The reciprocating screw 1 36 rotates and drives another reciprocating screw 1 36 to rotate through the pulley 37 and the belt 38. The rotation of the reciprocating screw 1 36 causes the movable plate 39 to move downward, and the movable plate 39 moves downward to drive the cross slitting knife 312, the push plate 316 and the frame plate 315 and other structures move downward, and the top of the frame plate 315 contacts the top of the frame 35, and the motor 41 is turned off. The push plate 316 and the frame plate 315 seal the top of the frame 35 to keep it warm. The heating plate 324 further heats and keeps the internal plastic warm to prevent temperature loss from causing the surface hardening of the material to affect the quality of the molding material. Then the motor 41 is started to drive the gear 1 42 to rotate forward, so that the one-way gear 1 320 drives the shaft 319 to rotate in the direction of rotation. The shaft 319 rotates to drive the triangular wheel 321 to rotate, and the triangular wheel 321 rotates. The bottom plate 34 rotates and contacts with the bottom plate 34, and the bottom plate 34 drives the slider 32 to squeeze the spring 1 33 in the chute, so that the bottom plate 34 swings back and forth, so that the material in the frame 35 is evenly spread inside the frame 35, and the motor 41 is started to reverse and the reciprocating screw 1 36 continues to rotate to make the movable plate 39 move down. Because the frame plate 315 is blocked by the frame 35, the movable plate 39 moves down along the connecting rod 310. When moving down, the cross cutting knife 312, the support plate 313, the spring 2 314 and the push plate 316 follow the movable plate 39 to move downward, and the push plate 316 is tightly pressed. The inner wall of the square frame 35 moves down to contact the top of the plastic, and then pressure is applied to the plastic to make it flow inside the square frame 35, further making the material evenly spread inside the square frame 35 to ensure the uniformity of the material thickness. Due to the obstruction of the plastic below, the push plate 316 cannot move further downward, but the support plate 313 and the cross slitting knife 312 will continue to move downward. The support plate 313 compresses the spring 2 314, and the cross slitting knife 312 moves down to contact the bottom of the square frame 35 to completely divide the material into multiple portions, and multiple electromagnets 323 are activated to attract the push plate 316; The controller 7 starts the hydraulic cylinder 12 to move the multi-station top mold 22 downward, and the multi-station top mold 22 moves downward to drive the rack 1 611, rack 2 612 and rack 3 613 to move downward. The rack 1 611 moves downward and first engages with the one-way gear 3 67, and moves downward to meet the direction of the one-way gear 3 67 driving the reciprocating screw 2 66 to rotate. The reciprocating screw 2 66 rotates to make the movable frame 69 drive the frame 35 and the structure connected to the frame 35 to move. The movement of the frame 35 drives the internal material to move toward the multi-station bottom mold 21. When the frame 35 is separated from the bottom plate 34, there is no restriction on the bottom. When the multiple pieces of material that are evenly cut move in turn on the top of the multiple multi-station bottom molds 21, one of the electromagnets 323 is turned off, and the magnetic attraction with the push plate 316 is released, and the pressed The compressed spring 2 314 begins to rebound. When the spring 2 314 rebounds, it pushes the push plate 316 downward to push the first piece of material in the box 35 into the first mold groove below, and then continues to move to the top of the second mold groove, and turns off the electromagnet 323 to put the second piece of material into the second mold groove. When the rack 1 611 and the one-way gear 3 67 are disengaged, the movable frame 69 moves to the wire tail of the reciprocating screw 2 66, and then the rack 3 613 is engaged with the gear 2 63, so that the screw 62 drives the movable block 65 to move, so that the reciprocating screw 2 66, the one-way gear 3 67, the movable frame 69, the box 35 and the structure connected to the box 35 move in a direction perpendicular to the moving direction just now, so that the box 35 and the structure connected to the box 35 move to the first mold groove. The top of the three mold grooves, and push the third piece of material into the third mold groove, then the rack three 613 is disengaged from the gear two 63, at this time the one-way gear three 67 moves to the bottom of the rack two 612, and then the rack two 612 moves down and engages with the one-way gear three 67, so that the movable frame 69, the frame 35 and the structure connected to the frame 35 are returned to the top along the reciprocating screw two 66, so that the frame 35 moves to the top of the fourth mold groove for feeding, and after feeding, it continues to move away from between the multi-station top mold 22 and the multi-station bottom mold 21 to complete the reset, and then the multi-station top mold 22 that moves down is inserted into the interior of the multi-station bottom mold 21, and the evenly placed materials are pressed into shape, while the reciprocating screw two 66 and the guide rod two 68 are located at the multi-station top mold 2 2, does not affect the overlapping pressing, and then the hydraulic cylinder 12 pushes the multi-station top mold 22 to reset and move upward, and the upward movement drives the rack 2 612 to engage with the one-way gear 3 67, but does not satisfy the direction of the one-way gear 3 67 to drive the reciprocating screw 2 66 to rotate, and then the rack 3 613 is engaged with the gear 2 63, so that the screw 62 rotates in the opposite direction to drive the moving block 65 and other structures to reset, and then the box 35 is reset to the top of the bottom plate 34, and then the rack 1 611 is engaged with the reset one-way gear 3 67, but does not satisfy the direction of the one-way gear 3 67 to drive the reciprocating screw 2 66 to rotate, after the multi-station top mold 22 is reset, the multiple plastic shells formed in the multi-station bottom mold 21 are manually taken out, and the motor 41 is started to drive the gear 1 42 to reverse,The reverse rotation of gear 1 42 satisfies the direction of rotation of reciprocating screw 1 36 driven by one-way gear 2 317, causing the movable plate 39 to move upward along the connecting rod 310, and the push plate 316, spring 2 314, support plate 313 and cross slitting knife 312 to move upward and reset, opening the box 35 and waiting for material to be added.
