[0004] In the above technical solution, each injection molded product has a sprue during production. After processing, the sprue of each injection molded product needs to be cut, which requires special cutting equipment, resulting in low processing efficiency of injection molded products. Summary of the Invention

[0005] The purpose of this invention is to provide a cyclic multi-station injection mold.

[0006] The technical problem solved by this invention is to address the inconvenience of processing the sprue of injection molded products, which requires separate cutting of the sprue in the prior art.

[0008] A further technical improvement of the present invention is that the cleaning component includes a rotary cutting component, which is installed at the output end of the longitudinal sliding component.

[0009] A further technical improvement of the present invention is that: the rotary cutting assembly includes a mounting and fixing sleeve, a rotary cutting sliding plate is slidably disposed inside the mounting and fixing sleeve, the rotary cutting sliding plate is installed at the output end of the longitudinal sliding assembly, a rotary cutting motor is fixed on the rotary cutting sliding plate, and a rotary cutting blade is disposed at the output end of the rotary cutting motor.

[0010] A further technical improvement of the present invention is that a dust suction hood is fixed to the side of the mounting sleeve, and a dust suction port is provided at the input end of the dust suction hood.

[0011] A further technical improvement of the present invention is that: the longitudinal sliding assembly includes a rotating screw, the rotating screw and the side base are rotatably connected, a limit rod is fixed on the side base, a sliding sleeve is threadedly connected to the rotating screw, the sliding sleeve and the limit rod are slidably connected, and the sliding sleeve and the rotary cutting sliding plate are fixedly connected.

[0012] A further technical improvement of the present invention is that: the grinding assembly includes a grinding plate, the grinding plate is installed at the output end of the grinding cylinder, the grinding cylinder is installed on the second gear, the second gear and the first gear are meshed and connected, and the first gear is driven by a drive motor.

[0013] A further technical improvement of the present invention is that: the side base is mounted on the limiting mounting seat, an adjusting rod is slidably arranged on the limiting mounting seat, an adjusting arc end is fixed to the end of the adjusting rod, a top limiting plate is fixed to the end of the adjusting rod, and a limiting spring is installed between the top limiting plate and the limiting mounting seat.

[0014] A further technical improvement of the present invention is that: a fifth gear is fixed at the end of the rotating screw, a fourth gear is meshed on the side of the fifth gear, a third gear is provided on the fourth gear, the fourth gear is rotatably connected to the side base, and an adjusting gear is rotatably provided on the top limiting plate. When the adjusting gear reaches the highest point, it meshes with the first gear and the third gear respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This application sets up a loading station, an injection station, a cleaning station, and an unloading station. First, the loading station performs preliminary cleaning of the lower injection mold at that position to ensure the cleanliness of the inside of the lower injection mold. Then, the lower injection mold is moved to the injection station by the rotation of the rotating disk. The injection station performs injection molding on the lower injection mold and rotates the molded product to the cleaning station. The cleaning components on the cleaning station clean the sprue of the molded product and perform rotary cutting on the sprue to obtain the preliminarily cleaned molded product. Then, the grinding components on the unloading station grind the cut position of the sprue of the molded product to obtain the finished injection sprue. Under the action of the rotating disk, a cyclic loading process can be realized, which can solve the problem of difficulty in cleaning the sprue in the prior art.

[0017] 2. This application, by adjusting the arc-shaped end, enables the determination of the rotation position of the lower injection mold using the arc-shaped end, thereby limiting the position of the lower injection mold. Specifically, when the end of the lower injection mold first contacts the arc-shaped end, the adjusting rod moves longitudinally on the limiting mounting seat. At this time, the limiting spring is stretched, which, through the meshing of the adjusting gear and the first gear, drives the operation of the longitudinal moving component. Thus, when grinding the injection molded product at the unloading position, the height of the rotary cutting component can be adjusted by rotating the screw, thereby enabling the rotary cutting operation of the rotary cutting component.

[0018] 3. In this application, a rotary cutting motor is used to drive a rotary cutting blade to cut the sprue. After cutting, the dust collection hood is used to remove the rotary cutting waste through the dust collection port, thus avoiding the problem of impurities accumulating inside the injection molded product and causing damage to the injection molded product when it is polished by the grinding plate. Therefore, this application can quickly clean the injection molded product. Attached Figure Description

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0028] Please see Figure 1-6 As shown, the circulating multi-station injection mold includes a rotating disk 1, which is installed at the output end of a rotating motor. The rotating motor drives the rotating disk 1 to rotate. Eight sets of injection molds 2 are set on the rotating disk 1. The rotation of the rotating disk 1 is used to change the position of the injection molds 2, thereby realizing rotary injection.

[0029] This application includes eight positions: a first loading position 5, a first injection position 6, a first cleaning position 7, a first unloading position 8, a second loading position 9, a second injection position 10, a second cleaning position 11, and a second unloading position 12. This allows for simultaneous molding of two sets of injections. Specifically, the lower injection mold 2 is cleaned at the first loading position 5 and the second loading position 9 to ensure no residual plastic components remain inside. Then, the rotating disc 1 rotates the cleaned lower injection mold 2 to the first injection position 6 and the second injection position 10. Positionally, the upper injection mold 3 and the lower injection mold 2 are coupled to form the injection mold. After injection molding, the lower injection mold 2 is rotated to the first cleaning position 7 and the second cleaning position 11 by rotating the rotating disk 1. The injection molded product on the lower injection mold 2 is processed by removing the sprue from the injection molded product. Then, by rotating the rotating disk 1, the injection molded product with the sprue removed is rotated to the first unloading position 8 and the second unloading position 12. The processed injection molded product is unloaded, realizing the complete injection molding process.

[0030] An injection molding assembly 4 is arranged longitudinally in the first injection position 6 and the second injection position 10. An upper injection mold 3 is arranged at the output end of the injection molding assembly 4. The upper injection mold 3 and the lower injection mold 2 are used to cooperate to form an injection cavity. That is, the injection of the injection molding assembly 4 allows the raw material to enter the injection cavity through the upper injection mold 3, thereby realizing injection molding.

[0031] A cleaning component 13 is provided at the first cleaning position 7 and the second cleaning position 11 to process the injection molded products on the first cleaning position 7 and the second cleaning position 11, that is, to cut off the sprue of the injection molded products.

[0032] The injection mold 2 includes a first cylinder 201, the output end of which is provided with a sliding support mold 209. A first limiting rod 202 is fixed on the sliding support mold 209, and a support base 205 is fixed to the end of the first limiting rod 202. An ejection cavity 207 is opened in the middle of the support base 205. A first push plate 204 is slidably arranged inside the ejection cavity 207. A plurality of ejection rods 206 are evenly fixed on the first push plate 204. A first pushing rod 203 is fixed to the side of the first push plate 204. The first pushing rod 203 is installed at the output end of the second cylinder 208, and the first pushing rod 203 and the sliding support mold 209 are slidably connected. In this application, the height of the sliding support mold 209 is first controlled by activating the first cylinder 201, allowing the support base 205 to move upward until it engages with the lower injection mold 2 to form an injection cavity. Then, a plastic solution is added to the injection cavity to achieve injection molding. After injection molding, the support base 205 is cooled to form the plastic product. The support base 205 then moves downward, separating the lower injection mold 2 from the upper injection mold 3. The rotating disk 1 then moves the lower injection mold 2 to the first unloading position 8 and the second unloading position 12. At this point, the second cylinder 208 is activated, controlling the first push rod 203 to move upward, causing the first push plate 204 to move upward inside the ejection cavity 207. This push rod 206 then pushes the molded product formed on the surface of the support base 205, separating the molded product from the support base 205.

[0033] First, the cleaning component 13 includes a positioning component and a rotary cutting component 1313. The positioning component is used to position the lower injection mold 2. When the lower injection mold 2 moves to the set position, the rotary cutting component 1313 is activated to cut the sprue of the injection molded product, thereby processing the injection molded product.

[0034] The positioning component includes an adjusting arc-shaped end 1312, which is arc-shaped and mounted on an adjusting rod 1311. The adjusting rod 1311 and the fixed part are slidably connected. When the injection mold 2 rotates to the corresponding position, the adjusting arc-shaped end 1312 contacts the edge of the injection mold 2. At this time, the adjusting arc-shaped end 1312 is pushed to gradually move upward, causing the adjusting rod 1311 to move upward until it reaches the set position. Then, the rotary cutting component 1313 is activated to perform the rotary cutting operation.

[0035] Specifically, an adjusting mounting base 1306 is fixed at the fixed point, and a limiting mounting base 1308 is fixed to one end of the adjusting mounting base 1306. A side base 1314 is fixed to the end of the limiting mounting base 1308 away from the adjusting mounting base 1306. The limiting mounting base 1308 and the adjusting rod 1311 are slidably connected. A top limiting seat is fixed to the end of the adjusting rod 1311, and a limiting spring 1316 is installed between the top limiting seat and the limiting mounting base 1308. When the adjusting rod 1311 is pushed upward, it slides inside the limiting mounting base 1308. At this time, the top limiting seat slides away from the limiting mounting base 1308, and the limiting spring 1316 is stretched.

[0036] Furthermore, the rotary cutting assembly 1313 is installed at the output end of the longitudinal moving assembly, that is, the longitudinal moving assembly controls the height of the rotary cutting assembly 1313, and then the rotary cutting assembly 1313 is used to cut the sprue.

[0037] The rotary cutting assembly 1313 includes a mounting sleeve 13131, which is fixedly mounted on a side base 1314. A rotary cutting sliding plate 13134 is slidably disposed inside the mounting sleeve 13131. The rotary cutting sliding plate 13134 is mounted on the output end of the longitudinal movement assembly. A rotary cutting motor 13132 is fixed on the rotary cutting sliding plate 13134, which drives a rotary cutting blade 13133. In other words, the rotary cutting motor 13132 drives the rotary cutting blade 13133 to rotate, thereby cutting the sprue. Specifically, in use, the longitudinal movement assembly drives the rotary cutting sliding plate 13134 to move longitudinally, controlling the height of the rotary cutting blade 13133, and moving the blade out of the mounting sleeve 13131 to cut the sprue.

[0038] In order to clean the inside of the finished product, a dust suction hood 13135 is fixedly installed at both ends of the mounting sleeve 13131. The input end of the dust suction hood 13135 is provided with a dust suction port 13136, which is used to adsorb the waste generated by rotary cutting with a large suction force to ensure that the inside of the injection molded product is relatively clean.

[0039] In order to further clean the injection molded products, grinding components are installed at the first unloading position 8 and the second unloading position 12. The grinding components are used to grind the sprue position to make the sprue position smoother.

[0040] The grinding assembly includes a grinding plate 1307, which is installed at the output end of a grinding cylinder 1305. The grinding cylinder 1305 is installed at the output end of a rotating assembly. Under the action of the rotating assembly, the grinding cylinder 1305 is driven to rotate, that is, the grinding plate 1307 is rotated to process the injection molded products on the first unloading position 8 and the second unloading position 12, that is, to fully grind the sprue on the injection molded products.

[0041] The rotating assembly includes a drive motor 1302, which is fixed at a fixed location. The drive motor 1302 drives the first gear 1301. The grinding cylinder 1305 is mounted on the second gear 1303. The first gear 1301 and the second gear 1303 are meshed together. When the drive motor 1302 rotates, it drives the first gear 1301 to rotate, which in turn drives the second gear 1303 to rotate the rod, thereby using the grinding plate 1307 to grind the sprue position.

[0042] The longitudinal movement component includes a rotating screw 1318, which is rotatably mounted on a side base 1314. A limiting rod 1315 is fixedly mounted on the side base 1314. A limiting sleeve 1319 is slidably mounted on the limiting rod 1315. The limiting sleeve 1319 is fixedly connected to a sliding sleeve 1317, which is threadedly connected to the rotating screw 1318. During use, the rotation of the rotating screw 1318 causes it to slide under the limiting sliding action of the limiting sleeve 1319, thereby controlling the longitudinal sliding of the limiting sleeve 1319. The limiting sleeve 1319 is fixedly connected to a rotary cutting sliding plate 13134, thus controlling the longitudinal sliding of the rotary cutting sliding plate 13134.

[0043] Furthermore, in order to achieve the rotation of the rotating screw 1318, a fifth gear 1323 is fixed at the end of the rotating screw 1318. An adjusting shaft 1310 is fixed on the top limiting seat, and the adjusting shaft 1310 is rotatably connected to the adjusting gear 1309. A third shaft 1320 is rotatably arranged on the side base 1314, and a fourth gear 1322 and a third gear 1321 are fixed on the third shaft 1320. The fourth gear 1322 is meshed with the fifth gear 1323, and the third gear 1321 is used to mesh with the adjusting gear 1309 when the adjusting gear 1309 moves upward to the highest position. At this time, the adjusting gear 1309 meshes with the first gear 1301.

[0044] In this application, the drive motor 1302 drives the first gear 1301 to rotate, which in turn drives the second gear 1303 to rotate. The grinding plate 1307 grinds the sprue of the injection molded product. At the same time, when the adjusting gear 1309 moves longitudinally, the first gear 1301 and the adjusting gear 1309 mesh, driving the adjusting gear 1309 to rotate, which in turn drives the third gear 1321 to rotate. Then, under the action of the rotation of the fourth gear 1322, the fifth gear 1323 rotates, which in turn drives the rotating screw 1318 to rotate, thereby controlling the rotary cutting assembly 1313 to perform rotary cutting operation and achieving complete cleaning of the sprue.

[0045] In use, the present invention first rotates the rotating disk 1 to the first loading position 5 and the second loading position 9. At the first loading position 5 and the second loading position 9, the lower injection mold 2 is subjected to adsorption treatment to remove impurities. Then, the rotating disk 1 rotates again to move the cleaned lower injection mold 2 to the first injection position 6 and the second injection position 10. At this time, the lower injection mold 2 at the first loading position 5 and the second loading position 9 is adsorbed and cleaned, and injection molding is performed at the first injection position 6 and the second injection position 10. After injection molding is completed, the rotating disk 1 rotates again, at which point the lower injection mold 2 at the first loading position 5 and the second loading position 9 is adsorbed and cleaned, and injection molding is performed at the first injection position 6 and the second injection position 10. The first cleaning position 7 and the second... The injection molded products on the second cleaning position 11 are rotary cut; finally, the rotation of the rotating disk 1 is used to clean the injection mold 2 on the first loading position 5 and the second loading position 9, to perform injection molding on the first injection position 6 and the second injection position 10, to perform rotary cutting on the injection molded products on the first cleaning position 7 and the second cleaning position 11, to grind the sprue position of the injection molded products on the first unloading position 8 and the second unloading position 12, and to unload them. At this time, the injection mold 2 on the first unloading position 8 and the second unloading position 12 are idle. After rotation, the injection mold 2 on the first unloading position 8 is rotated to the position of the second loading position 9, and the injection mold 2 on the second unloading position 12 is rotated to the position of the first loading position 5, so as to realize the cyclical replacement of the injection mold;

[0046] When processing the injection-molded product, first adjust the arc-shaped end 1312 to contact the edge of the lower injection mold 2. As the rotating disk 1 rotates, the arc-shaped end 1312 is pushed upward, that is, the adjusting rod 1311 slides on the limiting mounting seat 1308. At this time, the limiting spring 1316 is compressed, pushing the adjusting gear 1309 upward until the adjusting gear 1309 moves upward to the position of the first gear 1301, that is, when the adjusting gear 1309, the first gear 1301, and the third gear... When wheel 1321 is engaged, the rotation of rotating disk 1 stops. At this time, when drive motor 1302 starts, it drives first gear 1301 to rotate, which in turn drives second gear 1303 to rotate. Meanwhile, grinding cylinder 1305 moves grinding plate 1307, bringing it into contact with the sprue of the injection molded product. The grinding plate 1307 then grinds the injection molded products on the first and second unloading positions 8 and 12. During this process, adjusting gear 1309 is activated. The rotation of the gears causes the third gear 1321 to rotate, which in turn drives the fifth gear 1323 to rotate under the action of the fourth gear 1322. At this time, the rotating screw 1318 rotates, controlling the height of the limiting sleeve 1319, so that the rotary cutting sliding plate 13134 slides inside the mounting and fixing sleeve 13131 until the rotary cutting blade 13133 contacts the sprue position. At this time, the grinding plate 1307 finishes grinding, the drive motor 1302 is stopped, and the grinding plate 1307 is moved through the grinding cylinder 13 Adjustment 05 is set to a high level. At this point, the rotary cutting motor 13132 rotates, driving the rotary cutting blade 13133 to perform a rotary cutting operation. Then, the dust suction hood 13135 absorbs the impurities that fall off during rotary cutting, preventing the presence of impurities from affecting the normal use of the grinding plate 1307. Subsequently, the drive motor 1302 is started, causing the first gear 1301 to rotate in the opposite direction, thereby moving the rotary cutting blade 13133 upward and retracting the rotary cutting blade 13133.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
