Description

Technical Field

[0001] The present invention relates to the technical field of stick sleeve casting, and particularly relates to an automatic casting device for alloy stick sleeves. Background Art

[0002] A stick sleeve is a fixing device for holding stick bodies such as police batons and tactical batons. It needs to take into account characteristics such as practicality, firmness, beauty, and universality, and is made of materials such as plastic, leather, or alloy. Among them, the alloy stick sleeve has the best firmness and beauty. The stick sleeve is a standard product and can be efficiently and mass-produced through an automatic production line, which can not only reduce production costs but also ensure the quality of the product. The alloy stick sleeve casting devices in the prior art cannot achieve fully automatic continuous production of alloy stick sleeves, the loading and unloading process is cumbersome, and the degree of automation is low. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an automatic casting device for alloy stick sleeves, including a conveying mechanism for conveying the mold. The conveying mechanism includes a bottom plate, and a docking mechanism for docking the mold and a driving mechanism for driving the device are arranged on the conveying mechanism. The docking mechanism includes a wheel seat, and the wheel seat is fixedly installed on the bottom plate. The driving mechanism includes a bottom motor seat, and the bottom motor seat is fixedly installed on the bottom plate.

[0004] The conveying mechanism includes a lower mold track and an upper mold track fixedly installed on the bottom plate. A driving transmission column is rotatably installed on the upper mold track, and a lower docking gear and a driving wheel are fixedly installed on the driving transmission column. A first notch and a second notch are arranged on the upper mold track.

[0005] Further, the conveying mechanism further includes two lower mold driving wheels rotatably installed on the lower mold track. A lower transmission wheel is fixedly installed below the lower mold driving wheels. A lower mold transmission belt is wound around the two lower mold driving wheels. Six telescopic sleeves are fixedly installed on the lower mold transmission belt. A lower mold is fixedly installed on the telescopic sleeve. A vertical guide rod is fixedly installed on the lower mold, and the lower mold slides in the groove of the lower mold track.

[0006] Further, two upper mold driving columns are rotatably installed on the upper mold track. An upper transmission wheel and a side docking gear are fixedly installed on the upper mold driving column. An upper mold transmission belt is wound around the driving wheel and the two upper transmission wheels. An upper mold transmission shell is fixedly installed on the outer side of the upper mold transmission belt. Six lifting guide sleeves are fixedly installed on the upper mold transmission shell. An upper mold slides on the lifting guide sleeve. An intermediate gear is rotatably installed on the bottom plate. The intermediate gear meshes with the side docking gear. A bottom transmission belt is wound around the intermediate gear and the lower transmission wheel.

[0007] When the lifting guide sleeve is located at the second notch and the first notch, the upper mold reaches above the vertical guide rod, and the upper mold can slide up and down along the vertical guide rod.

[0008] The gear with missing teeth drives the lower mating gear, the driving transmission column and the driving wheel to rotate intermittently. The driving wheel drives the upper die transmission belt and the upper die transmission housing to rotate, thereby driving the upper die to rotate through the lifting guide sleeve. The upper die transmission belt drives the upper transmission wheel, the upper die transmission column and the side mating gear to rotate. The side mating gear drives the intermediate gear to rotate, and drives the lower transmission wheel and the lower die transmission wheel to rotate through the bottom transmission belt. The lower die transmission wheel drives the lower die transmission belt to rotate, thereby driving the lower die and the vertical guide rod to move along the arc groove of the lower die track. The rotation directions of the lower transmission wheel and the upper transmission wheel are opposite, and the rotation directions of the lower die transmission belt and the upper die transmission housing are opposite. The moving distances of the upper die and the lower die each time are the same. The upper die on the lifting guide sleeve at the second notch, through the descent of the lifting block and the cooperation of the gravity of the upper die, causes the upper die to descend along the vertical guide rod onto the lower die. The upper die on the lifting guide sleeve at the first notch slides upward along the vertical guide rod under the upward action of the lifting block. Subsequently, when the upper die track and the upper die transmission housing rotate again, the upper die at the second notch is placed on the lower die and the vertical guide rod, and the upper die at the first notch is driven by the lifting guide sleeve to continue moving on the upper die track. After the upper die and the lower die are paired, after advancing one station, the molten metal is poured into the upper die.

[0009] Further, the docking mechanism includes an external gear runner rotatably installed in the wheel seat. Teeth are provided on the edge of the external gear runner. Two vertical guide rails are fixedly installed on the bottom plate. The vertical guide rails are fixedly installed with the upper die track. Lifting guide blocks are respectively slidably installed on the two vertical guide rails. A lifting frame is slidably installed on the lifting guide block. The lifting frame is eccentrically rotatably installed with the external gear runner. A lifting block is slidably installed on the lifting frame. The two lifting blocks are respectively located below the second notch and the first notch.

[0010] Further, a first telescopic rod is fixedly installed below the lifting block. A second telescopic rod is slidably installed in the first telescopic rod. A third telescopic rod is slidably installed in the second telescopic rod. A fourth telescopic rod is slidably installed in the third telescopic rod. A fifth telescopic rod is slidably installed in the fourth telescopic rod. The fifth telescopic rod is fixedly installed with the bottom plate.

[0011] The rotation of the external gear runner drives the movement of the lifting frame, causing the lifting guide block to lift along the vertical guide rail. Through the sliding of the lifting block in the motor gear, the lifting block is driven to lift and lower. The first telescopic rod, the second telescopic rod, the third telescopic rod, the fourth telescopic rod and the fifth telescopic rod relatively expand and contract. Through the descent of the lifting block and the cooperation of the gravity of the upper die, the upper die at the second notch descends along the vertical guide rod onto the lower die, realizing the docking of the lower die and the upper die and preparing for the casting of the next station. Through the ascent of the lifting block, the upper die at the first notch ascends along the vertical guide rod and reaches the lifting guide sleeve, realizing demoulding. The finished product after casting is located on the lower die.

[0012] Further, the driving mechanism includes a bottom motor fixedly installed on the bottom motor base. A motor gear is fixedly installed on the motor shaft of the bottom motor. A bottom gear shaft is rotatably installed below the upper die track. A bottom gear, a toothless gear, and an upper bevel gear are fixedly installed on the bottom gear shaft. An output transmission belt is wound around the motor gear and the bottom gear. The toothless gear meshes with the lower docking gear.

[0013] Further, a lower extension frame is fixedly installed below the upper die track. A horizontal gear shaft is rotatably installed on the lower extension frame. An intermittent gear and an upper gear are fixedly installed on the horizontal gear shaft. A semi-tooth gear is rotatably installed on the lower extension frame. A side bevel gear is fixedly installed on the semi-tooth gear. The side bevel gear meshes with the upper bevel gear. The semi-tooth gear meshes with the intermittent gear. A lower gear is rotatably installed on the wheel seat. An internal gear is fixedly installed on the lower gear. The lower gear meshes with the upper gear. The internal gear meshes with the external tooth runner.

[0014] The bottom motor drives the motor gear to rotate, drives the bottom gear, the bottom gear shaft, the toothless gear, and the upper bevel gear to rotate through the output transmission belt. The toothless gear drives the lower docking gear to rotate intermittently. Each time the toothless gear rotates one circle, it drives the lower die and the upper die to advance one working position. The upper bevel gear drives the side bevel gear and the semi-tooth gear to rotate. The semi-tooth gear drives the intermittent gear, the horizontal gear shaft, and the upper gear to rotate intermittently, drives the lower gear and the internal gear to rotate, and thus drives the external tooth runner to rotate. Each time the toothless gear rotates one circle, it drives the external tooth runner to rotate one circle.

[0015] Before the toothless gear rotates the first quarter circle, the lifting block at the second notch descends, and the lifting block at the first notch ascends, so that the upper die at the second notch falls onto the lower die, and the upper die at the first notch is lifted from the lower die. At this time, the upper die track and the lower die transmission belt do not rotate; when the toothless gear continues to rotate a quarter circle, the lifting block does not rise or fall, and the upper die track and the lower die transmission belt drive the lower die and the upper die to advance half a working position; when the toothless gear continues to rotate a quarter circle, the lifting block at the second notch rises and resets, and the lifting block at the first notch descends and resets, and the upper die track and the lower die transmission belt do not rotate; when the toothless gear continues to rotate a quarter circle, the upper die track and the lower die transmission belt advance another half a working position, and the lifting block does not rise or fall. At this time, the upper die and the lower die originally located at the second notch move along the lower die track, and accumulate to move one working position to reach the casting station. The molten metal is cast into the upper die. The upper die and the lower die originally located at the casting station move to the first notch, and are ready for the separation of the upper die and the lower die, and so on.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: (1) The conveying mechanism provided in the present invention drives the upper mold and the lower mold to move synchronously, and under the action of the docking mechanism, the upper mold and the lower mold are docked before casting, and the upper mold and the lower mold are automatically separated after casting is completed, realizing demoulding, with a high degree of automation; (2) The driving mechanism provided in the present invention drives the toothless gear to rotate. In the first quarter turn, the upper mold at the second notch falls onto the lower mold, and the upper mold at the first notch is picked up from the lower mold; the toothless gear continues to rotate a quarter turn, and the lower mold and the upper mold advance half a work station; the toothless gear continues to rotate a quarter turn, and the lifting block at the second notch rises and resets, and the lifting block at the first notch descends and resets; the toothless gear continues to rotate a quarter turn, and the upper mold track and the lower mold conveyor belt advance another half a work station, and so on, with a high degree of automation and good continuity; (3) The docking mechanism provided in the present invention drives the lifting blocks at the first notch and the second notch to rise and fall simultaneously each time, so as to realize simultaneously dropping the upper mold to be cast onto the lower mold and removing the upper mold after casting and cooling from the lower mold.

A first notch 103 and a second notch 123 are provided on the upper die track 111.

[0032] AsFigures 2 - 4 As shown, the conveying mechanism further includes two lower die driving wheels 104 rotatably mounted on the lower die track 102. A lower driving wheel 105 is fixedly mounted below the lower die driving wheels 104. A lower die driving belt 109 is wound around the two lower die driving wheels 104. Six telescopic sleeves 106 are fixedly mounted on the lower die driving belt 109. A lower die 107 is fixedly mounted on the telescopic sleeve 106. A vertical guide rod 108 is fixedly mounted on the lower die 107. The lower die 107 slides in the groove of the lower die track 102.

[0033] As Figures 2 - 4 shown, two upper die driving columns 115 are rotatably mounted on the upper die track 111. An upper driving wheel 116 and a side docking gear 120 are fixedly mounted on the upper die driving columns 115. An upper die driving belt 110 is wound around the driving wheel 118 and the two upper driving wheels 116. An upper die driving housing 112 is fixedly mounted on the outer side of the upper die driving belt 110. Six lifting guide sleeves 113 are fixedly mounted on the upper die driving housing 112. An upper die 114 is slidably mounted on the lifting guide sleeve 113. An intermediate gear 121 is rotatably mounted on the bottom plate 101. The intermediate gear 121 meshes with the side docking gear 120. A bottom driving belt 122 is wound around the intermediate gear 121 and the lower driving wheel 105.

[0034] As Figures 2 - 4 shown, when the lifting guide sleeve 113 is located at the second notch 123 and the first notch 103, the upper die 114 reaches above the vertical guide rod 108, and the upper die 114 can slide up and down along the vertical guide rod 108.

[0035] The missing-tooth gear 307 drives the docking gear 119, the driving transmission column 117 and the driving wheel 118 to rotate intermittently. The driving wheel 118 drives the upper die transmission belt 110 and the upper die transmission housing 112 to rotate, thereby driving the upper die 114 to rotate through the lifting guide sleeve 113. The upper die transmission belt 110 drives the upper transmission wheel 116, the upper die transmission column 115 and the side docking gear 120 to rotate. The side docking gear 120 drives the intermediate gear 121 to rotate, and drives the lower transmission wheel 105 and the lower die transmission wheel 104 to rotate through the bottom transmission belt 122. The lower die transmission wheel 104 drives the lower die transmission belt 109 to rotate, thereby driving the lower die 107 and the vertical guide rod 108 to move along the arc groove of the lower die track 102. The rotation directions of the lower transmission wheel 105 and the upper transmission wheel 116 are opposite, and the rotation directions of the lower die transmission belt 109 and the upper die transmission housing 112 are opposite. The distances moved by the upper die 114 and the lower die 107 each time are the same. The upper die 114 on the lifting guide sleeve 113 at the second notch 123, through the descent of the lifting block 204 and the gravity of the upper die 114, causes the upper die 114 to descend along the vertical guide rod 108 onto the lower die 107. The upper die 114 on the lifting guide sleeve 113 at the first notch 103 slides upward along the vertical guide rod 108 under the upward action of the lifting block 204. Subsequently, when the upper die track 111 and the upper die transmission housing 112 rotate again, the upper die 114 at the second notch 123 is placed on the lower die 107 and the vertical guide rod 108, and the upper die 114 at the first notch 103 is driven by the lifting guide sleeve 113 to continue moving on the upper die track 111. After the upper die 114 and the lower die 107 are paired, after advancing one station, the molten metal is poured into the upper die 114.

[0036] As Figures 5 - 8 shown, the docking mechanism includes an external gear rotating wheel 205 rotatably installed in the wheel seat 201. Teeth are provided on the edge of the external gear rotating wheel 205. Two vertical guide rails 202 are fixedly installed on the bottom plate 101. The vertical guide rails 202 are fixedly installed with the upper die track 111. Lifting guide blocks 211 are respectively slidably installed on the two vertical guide rails 202. A lifting frame 203 is slidably installed on the lifting guide block 211. The lifting frame 203 is eccentrically rotatably installed with the external gear rotating wheel 205. A lifting block 204 is slidably installed on the lifting frame 203. The two lifting blocks 204 are respectively located below the second notch 123 and the first notch 103.

[0037] As Figures 5 - 8 shown, a first telescopic rod 206 is fixedly installed below the lifting block 204. A second telescopic rod 207 is slidably installed in the first telescopic rod 206. A third telescopic rod 208 is slidably installed in the second telescopic rod 207. A fourth telescopic rod 209 is slidably installed in the third telescopic rod 208. A fifth telescopic rod 210 is slidably installed in the fourth telescopic rod 209. The fifth telescopic rod 210 is fixedly installed with the bottom plate 101.

[0038] The rotation of the external gear runner 205 drives the movement of the lifting frame 203, causing the lifting guide block 211 to move up and down along the vertical guide rail 202. Through the sliding of the lifting block 204 within the motor gear 303, the lifting block 204 is driven to move up and down. The first telescopic rod 206, the second telescopic rod 207, the third telescopic rod 208, the fourth telescopic rod 209, and the fifth telescopic rod 210 relatively expand and contract. When the lifting block 204 descends, combined with the gravity of the upper mold 114, the upper mold 114 at the second notch 123 descends along the vertical guide rod 108 and lands on the lower mold 107, realizing the docking of the lower mold 107 and the upper mold 114, preparing for the casting at the next station. When the lifting block 204 ascends, the upper mold 114 at the first notch 103 ascends along the vertical guide rod 108 and reaches the lifting guide sleeve 113, realizing demolding. The finished product after casting is located on the lower mold 107.

[0039] As Figures 9 - 11 shown, the driving mechanism includes a bottom motor 302 fixedly installed on the bottom motor base 301. A motor gear 303 is fixedly installed on the motor shaft of the bottom motor 302. A bottom gear shaft 304 is rotatably installed below the upper mold track 111. A bottom gear 306, a toothless gear 307, and an upper bevel gear 308 are fixedly installed on the bottom gear shaft 304. An output transmission belt 305 is wound around the motor gear 303 and the bottom gear 306. The toothless gear 307 meshes with the lower docking gear 119.

[0040] As Figures 9 - 11 shown, a lower extension frame 309 is fixedly installed below the upper mold track 111. A horizontal gear shaft 312 is rotatably installed on the lower extension frame 309. An intermittent gear 313 and an upper gear 314 are fixedly installed on the horizontal gear shaft 312. A semi-tooth gear 311 is rotatably installed on the lower extension frame 309. A side bevel gear 310 is fixedly installed on the semi-tooth gear 311. The side bevel gear 310 meshes with the upper bevel gear 308. The semi-tooth gear 311 meshes with the intermittent gear 313. A lower gear 315 is rotatably installed on the wheel seat 201. An internal gear 316 is fixedly installed on the lower gear 315. The lower gear 315 meshes with the upper gear 314. The internal gear 316 meshes with the external gear runner 205.

[0041] The bottom motor 302 drives the motor gear 303 to rotate, drives the bottom gear 306, the bottom gear shaft 304, the toothless gear 307 and the upper bevel gear 308 to rotate through the output transmission belt 305. The toothless gear 307 drives the lower docking gear 119 to rotate intermittently. Every time the toothless gear 307 rotates one circle, it drives the lower mold 107 and the upper mold 114 to advance one station. The upper bevel gear 308 drives the side bevel gear 310 and the half-tooth gear 311 to rotate. The half-tooth gear 311 drives the intermittent gear 313, the horizontal gear shaft 312 and the upper gear 314 to rotate intermittently, drives the lower gear 315 and the internal gear 316 to rotate, and thus drives the external gear runner 205 to rotate. Every time the toothless gear 307 rotates one circle, it drives the external gear runner 205 to rotate one circle.

[0042] When the toothless gear 307 rotates the first quarter circle, the lifting block 204 at the second notch 123 descends, and the lifting block 204 at the first notch 103 ascends, so that the upper mold 114 at the second notch 123 falls onto the lower mold 107, and the upper mold 114 at the first notch 103 is lifted from the lower mold 107. At this time, the upper mold track 111 and the lower mold transmission belt 109 do not rotate; when the toothless gear 307 continues to rotate a quarter circle, the lifting block 204 does not rise or fall, and the upper mold track 111 and the lower mold transmission belt 109 drive the lower mold 107 and the upper mold 114 to advance half a station; when the toothless gear 307 continues to rotate a quarter circle, the lifting block 204 at the second notch 123 rises and resets, the lifting block 204 at the first notch 103 descends and resets, and the upper mold track 111 and the lower mold transmission belt 109 do not rotate; when the toothless gear 307 continues to rotate a quarter circle, the upper mold track 111 and the lower mold transmission belt 109 advance another half a station, and the lifting block 204 does not rise or fall. At this time, the upper mold 114 and the lower mold 107 originally located at the second notch 123 move along the lower mold track 102, and move a total of one station to reach the casting station. The molten metal is cast into the upper mold 114. The upper mold 114 and the lower mold 107 originally located at the casting station move to the first notch 103, preparing for the separation of the upper mold 114 and the lower mold 107, and so on.

[0043] The working principle of an alloy stick sleeve automatic casting device disclosed in the present invention is as follows: a bottom motor 302 drives a motor gear 303 to rotate, and drives a bottom gear 306, a bottom gear shaft 304, a toothless gear 307 and an upper bevel gear 308 to rotate through an output transmission belt 305; the toothless gear 307 drives a lower docking gear 119 to rotate intermittently; each rotation of the toothless gear 307 drives a lower mold 107 and an upper mold 114 to advance one station; the upper bevel gear 308 drives a side bevel gear 310 and a half-tooth gear 311 to rotate; the half-tooth gear 311 drives an intermittent gear 313, a transverse gear shaft 312 and an upper gear 314 to rotate intermittently, and drives a lower gear 315 and an inner gear 316 to rotate, thereby driving an outer gear rotating wheel 205 to rotate; each rotation of the toothless gear 307 drives the outer gear rotating wheel 205 to rotate one circle. The toothless gear 307 drives the lower docking gear 119, the active transmission column 117 and the active wheel 118 to rotate intermittently, the active wheel 118 drives the upper die transmission belt 110 and the upper die transmission shell 112 to rotate, thereby driving the upper die 114 to rotate through the lifting guide sleeve 113, the upper die transmission belt 110 drives the upper transmission wheel 116, the upper die transmission column 115 and the side docking gear 120 to rotate, the side docking gear 120 drives the intermediate gear 121 to rotate, and drives the lower transmission wheel 105 and the lower die transmission wheel 104 to rotate through the bottom transmission belt 122, the lower die transmission wheel 104 drives the lower die transmission belt 109 to rotate, thereby driving the lower die 107 and the vertical guide rod 108 to move along the arc groove of the lower die track 102, the lower transmission wheel 105 and the upper transmission wheel 116 rotate in opposite directions, the lower die transmission belt 109 and the upper die transmission shell 112 rotate in opposite directions, the upper die 114 and the lower die The distance that the mold 107 moves each time is the same. The upper mold 114 on the lifting guide sleeve 113 located at the second notch 123 is lowered along the vertical guide rod 108 and falls onto the lower mold 107 through the descent of the lifting block 204 and the gravity of the upper mold 114. The upper mold 114 on the lifting guide sleeve 113 located at the first notch 103 slides upward along the vertical guide rod 108 under the rising action of the lifting block 204. Then, when the upper mold track 111 and the upper mold transmission shell 112 rotate again, the upper mold 114 located at the second notch 123 is placed on the lower mold 107 and the vertical guide rod 108. The upper mold 114 located at the first notch 103 is driven by the lifting guide sleeve 113 to continue to move on the upper mold track 111. When the upper mold 114 and the lower mold 107 are paired, they move forward one station and cast the molten metal into the upper mold 114.The rotation of the external gear runner 205 drives the movement of the lifting frame 203, causing the lifting guide block 211 to move up and down along the vertical guide rail 202. Through the sliding of the lifting block 204 within the motor gear 303, the lifting block 204 is driven to move up and down. The first telescopic rod 206, the second telescopic rod 207, the third telescopic rod 208, the fourth telescopic rod 209, and the fifth telescopic rod 210 relatively expand and contract. When the lifting block 204 descends, combined with the gravity of the upper mold 114, the upper mold 114 at the second notch 123 descends along the vertical guide rod 108 and lands on the lower mold 107, realizing the docking of the lower mold 107 and the upper mold 114, and preparing for the casting at the next station. When the lifting block 204 ascends, the upper mold 114 at the first notch 103 ascends along the vertical guide rod 108 and reaches the lifting guide sleeve 113, realizing demolding. The finished product after casting is located on the lower mold 107. When the missing-tooth gear 307 rotates the first quarter turn, the lifting block 204 at the second notch 123 descends, and the lifting block 204 at the first notch 103 ascends, causing the upper mold 114 at the second notch 123 to land on the lower mold 107, and the upper mold 114 at the first notch 103 to be lifted from the lower mold 107. At this time, the upper mold track 111 and the lower mold conveyor belt 109 do not rotate; when the missing-tooth gear 307 continues to rotate a quarter turn, the lifting block 204 does not move up and down, and the upper mold track 111 and the lower mold conveyor belt 109 drive the lower mold 107 and the upper mold 114 to advance half a station; when the missing-tooth gear 307 continues to rotate a quarter turn, the lifting block 204 at the second notch 123 rises to reset, and the lifting block 204 at the first notch 103 descends to reset, and the upper mold track 111 and the lower mold conveyor belt 109 do not rotate; when the missing-tooth gear 307 continues to rotate a quarter turn, the upper mold track 111 and the lower mold conveyor belt 109 advance another half a station, and the lifting block 204 does not move up and down. At this time, the upper mold 114 and the lower mold 107 originally located at the second notch 123 move along the lower mold track 102, and accumulate to move one station to reach the casting station, and the molten metal is cast into the upper mold 114. The upper mold 114 and the lower mold 107 originally located at the casting station move to the first notch 103, preparing for the separation of the upper mold 114 and the lower mold 107, and so on.
