[0001] The utility model relates to a gate truncating mechanism of a capacitor box injection molding device, specifically a gate truncating mechanism of a capacitor box injection molding device, belonging to the technical field of capacitor box injection molding. Background Technique
[0002] A capacitor box is a specially designed housing or package for installing and protecting capacitors. Capacitors play a crucial role in electronic circuits, and the function of the capacitor box is to ensure the stability of the capacitor and extend its service life. During production, plastic raw materials are poured into a mold to form a capacitor box. Since a part of the surface of the capacitor box corresponding to the gate will protrude after casting and molding, it is necessary to truncate the protruding part on the surface of the capacitor box.
[0003] The existing truncating mechanism will directly use a truncating knife to truncate the gate at the surface of the capacitor box after the capacitor box is injection molded. Sharp edges or burrs will be formed at the truncating position. These sharp edges and burrs will affect the production quality of the capacitor box, and when workers pick up the capacitor box, the sharp edges and burrs may scratch the workers. Content of the Utility Model
[0004] The purpose of the utility model is to provide a gate truncating mechanism of a capacitor box injection molding device to solve the problem that sharp edges or burrs will be formed after truncating the gate of the capacitor box in the prior art.

The inner wall of the third U-shaped frame 35 is fixedly connected with a grinding plate 36. The inner wall of the third U-shaped frame 35 is fixedly connected with a cutting knife 37. The cutting knife 37 and the grinding plate 36 are adapted to each other. First, the cutting knife 37 truncates the gate of the capacitor box, and then the grinding plate 36 can grind the truncated position.
[0028] The outer surface of the internally threaded connecting frame 33 is rotatably connected with a rotating pipe 38. The rotating pipe 38 is slidably connected to the outer surface of the threaded rod 32. The outer surface of the rotating pipe 38 is fixedly connected with a first gear 39. The inner wall of the second U-shaped frame 34 is rotatably connected with a rotating rod 311. One end of the rotating rod 311 close to the first gear 39 is fixedly connected with a second gear 310. The first gear 39 meshes with the second gear 310. Under the meshing action of the first gear 39 and the second gear 310, the rotation of the rotating pipe 38 can drive the rotating rod 311 to rotate.
[0029] One end of the rotating rod 311 far from the second gear 310 is fixedly connected with a rotating plate 312. The outer surface of the rotating plate 312 is fixedly connected with a revolving rod 313. The outer surface of the third U-shaped frame 35 is fixedly connected with a sliding frame 314. The revolving rod 313 is slidably connected to the inner wall of the sliding frame 314. When the rotating rod 311 rotates, it drives the revolving rod 313 to revolve, and makes the revolving rod 313 push the sliding frame 314 to move reciprocally.
[0030] Two first guide rods 315 are fixedly connected to the inner wall of the first U-shaped frame 31. Both of the two first guide rods 315 penetrate through the internally threaded connecting frame 33 and are slidably connected to the internally threaded connecting frame 33. The first guide rods 315 play a guiding role for the movement of the internally threaded connecting frame 33.
[0031] Two limiting strips 316 are fixedly connected to the inner wall of the rotating pipe 38. Both of the two limiting strips 316 are slidably connected to the outer surface of the threaded rod 32. The threaded rod 32 is provided with a chute adapted to the limiting strips 316, so that the rotating pipe 38 can slide on the surface of the threaded rod 32, and when the threaded rod 32 rotates, it can drive the rotating pipe 38 to rotate synchronously.
[0032] A second guide rod 317 is fixedly connected to the inner wall of the second U-shaped frame 34. Two sliding pipes 318 are fixedly connected to the upper surface of the third U-shaped frame 35. Both of the two sliding pipes 318 are slidably connected to the outer surface of the second guide rod 317. The second guide rod 317 and the sliding pipes 318 play a guiding role for the movement of the third U-shaped frame 35 relative to the second U-shaped frame 34.
[0033] Please refer to Figure 1, a mold assembly 4 is provided on the upper surface of the bottom plate 1. The mold assembly 4 includes an upper mold 43 and a lower mold 41 fixedly connected to the upper surface of the bottom plate 1. The lower mold 41 and the upper mold 43 are adapted to each other. When the lower mold 41 and the upper mold 43 are closed, raw materials can be injected into the lower mold 41 through the pouring holes provided on the upper mold 43, and the capacitor box can be formed.
[0034] A hydraulic rod 42 is hinged to the outer surface of the above-mentioned upper mold 43. One end of the hydraulic rod 42 away from the upper mold 43 is hinged to the inner wall of the fixed frame 2. A connecting plate 44 is fixedly connected to the outer surface of the upper mold 43. The connecting plate 44 is hinged to the upper surface of the bottom plate 1. Under the hinge action of the connecting plate 44, by controlling the telescopic movement of the hydraulic rod 42, the upper mold 43 can be driven to close or open.
[0035] Please refer specifically to Figure 1 , an electric push rod 5 is fixedly connected to the inner wall of the fixed frame 2. The bottom end of the electric push rod 5 is fixedly connected to the upper surface of the first U-shaped frame 31. The telescopic movement of the electric push rod 5 can drive the first U-shaped frame 31 to move up and down.
[0036] Working principle: Control the hydraulic rod 42 to extend, so that the upper mold 43 and the lower mold 41 are closed. Inject raw materials into the lower mold 41 through the pouring holes of the upper mold 43. After the capacitor box is formed, shorten the hydraulic rod 42 to drive the upper mold 43 to open, and control the electric push rod 5 to extend, so that the first U-shaped frame 31 moves down to the position of the capacitor box. Control the motor on the first U-shaped frame 31 to run, so that the threaded rod 32 rotates and drives the internally threaded connecting frame 33 and the cutting knife 37 to move towards the protrusion at the gate of the capacitor box. Under the action of the limiting strip 316, the threaded rod 32 drives the rotating tube 38 to rotate, and drives the rotating rod 311 to rotate through the first gear 39 and the second gear 310. At this time, the revolution rod 313 makes a revolution movement, and pushes the sliding frame 314 to make a reciprocating movement, and at the same time drives the polishing plate 36 and the cutting knife 37 to make a reciprocating movement. The cutting knife 37 approaches the protrusion at the gate of the capacitor box and makes a reciprocating movement, so that the cutting knife 37 cuts off the protrusion at the gate, and then the polishing plate 36 makes a reciprocating movement to polish the cutting position. This device can cut off the surface gate of the capacitor box and polish the cutting position at the same time, improving the production quality of the capacitor box.
