Description

Technical Field

[0001] The present invention relates to the technical field of rubber sole production, and particularly relates to a device for rubber sole pattern forming. Background Art

[0002] A rubber sole refers to a sole made of rubber. Rubber sole materials can generally be divided into natural rubber or synthetic rubber. The advantage of natural rubber is that it is very soft and has excellent elasticity, which can be suitable for various sports and play a shock-absorbing role. However, its disadvantages are also obvious, that is, poor oil resistance, ozone aging resistance and heat-oxygen aging resistance. Natural rubber is mostly used for indoor sports shoes. Most of the existing rubber soles are produced by injecting glue using molds. Since the production cost of molds is relatively high, replacing the sole pattern requires replacing a whole set of molds, which is very inconvenient and costly. Moreover, the existing molds are mostly in two halves, and the mold joint line of the produced soles is very obvious, which requires manual grinding alone, is time-consuming and laborious, and wastes raw materials. Therefore, it is necessary to invent a device for rubber sole pattern forming to solve the above problems. Summary of the Invention

[0020] The beneficial effects of the present invention compared with the prior art are as follows:

[0021] 1. The mold plate under the shoe sole can be replaced with different shoe sole pattern styles. After replacement, it can be re-fixed in the middle of the U-shaped frame. Manually opening the locking buckle can separate the upper template and the lower pressing frame, and different-shaped upper templates can be replaced, so that different shapes or patterns can be formed on the upper surface of the shoe sole pressed by the upper template.

[0022] 2. Inject rubber through the rubber injection tube into the corresponding shoe sole mold and fill it up. Then, the lower pressing frame is pushed by the first electric cylinder, so that the upper template moves downward. The upper molds on the lower end surface of the upper template are respectively pressed into the shoe sole mold to compact the rubber inside the shoe sole mold and form a certain shape. During the pressing process, the excess rubber liquid will be extruded from the diversion groove and flow into the collection funnel below through the recovery hole, completing the recovery of the excess rubber, saving raw materials. Compared with the traditional production mode, a mold joint line will be formed around the shoe sole, which is more material-saving, and the cutting and grinding will be more convenient.

[0023] 3. After the shoe sole is formed, the motor A drives the rotating block to rotate, thereby driving the mold plate under the shoe sole to rotate 180 degrees so that the shoe sole mold faces downward. The first electric cylinder is used to push the upper template to press down the ejection frame, so that the small rod of the ejection frame extends out of the ejection hole to push out the formed shoe sole in the shoe sole mold. The shoe sole will fall onto the conveyor belt waiting below, completing the automatic demolding of the shoe sole.

[0024] 4. The third electric cylinder is used to push the cutting knife downward to cut off the excess rubber on both sides of the shoe sole. Two grinding motors are started to drive the grinding heads on both sides to rotate and grind the cutting positions on both sides of the shoe sole. After grinding, the side surface of the shoe sole is smooth and traceless, and the produced shoe sole is more beautiful.

[0025] 5. While grinding the shoe sole, the main body part, the lower mold part and the upper mold part work coordinately to continue producing rubber shoe soles. The two operations are carried out simultaneously, which improves the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The lower ends of the two expansion rods 506 on the right side are fixedly connected to the support plate of the grinding motor 507. There are two grinding motors 507. The shafts of the two grinding motors 507 are respectively fixedly connected to the two grinding heads 508. The two grinding heads 508 are respectively located on both sides of the shoe sole; The upper plate of the cutting knife 509 is fixedly connected to the two expansion rods 506 on the left side. A camera is provided under the upper plate of the cutting knife 509. The camera is used to identify the position of the redundant rubber on the shoe sole. There are two cutting knives 509. The two cutting knives 509 are respectively located on both sides of the shoe sole. Specifically, the two ends of the shoe sole are pressed by the positioning rods 502. The position of the redundant rubber on the shoe sole is identified by the camera under the cutting knife 509. The motor E 503 drives the slider 504 to move, thereby driving the cutting knife 509 to move to the specified position. The third electric cylinder 505 pushes the cutting knife 509 downward to cut off the redundant rubber on both sides of the shoe sole. Then, the motor E 503 continues to drive the slider 504 to move, so that the grinding motor 507 moves to the cutting position. Then, the third electric cylinder 505 presses down the plate of the grinding motor 507. The two grinding motors 507 are started to drive the grinding heads 508 on both sides to rotate and grind the cutting positions on both sides of the shoe sole.

[0057] Working principle: When the present invention is in use, first place the lower mold plate 209 of the shoe sole that needs to be injected with glue in the middle of the U-shaped frame 201. The rectangular hole on the side of the lower mold plate 209 of the shoe sole cooperates with the rotating block 203. Push the side sliding plate 208 so that the middle axis of the side sliding plate 208 is inserted into the circular hole on the side of the lower mold plate 209 of the shoe sole. Then, drive the bidirectional lead screw 207 to rotate through the motor B 206, so that the two side fixing rods 204 move towards the middle. The rods of the side fixing rods 204 are inserted into the holes at the front and rear ends of the lower mold plate 209 of the shoe sole, and the lower mold plate 209 of the shoe sole is completely fixed. The lower mold plate 209 of the shoe sole can be replaced with different shoe sole pattern styles. After replacement, it can be fixed back in the middle of the U-shaped frame 201. Manually open the locking buckle 309 to separate the upper template 308 and the lower pressing frame 307, and different shaped upper templates 308 can be replaced, so that different shapes or patterns are formed on the upper surface of the shoe sole pressed by the upper template 308;

[0058] The hollow frame 103 is pushed to the upper position of the lower mold plate 209 of the sole by the telescopic sleeve 104. At this time, the plurality of rubber injection heads below the rubber injection tube 105 correspond to the sole mold 210 one by one. The rubber is injected into the hollow frame 103 through the tube of the rubber storage box 102, enters the rubber injection tube 105, and then is injected into the corresponding sole mold 210 and filled. Then the telescopic sleeve 104 moves the hollow frame 103 away, and the gear 304 is driven to rotate by the motor C303, thereby driving the rack rod 305 to move to the left side so that the upper mold plate 308 is located directly above the lower mold plate 209 of the sole, and then the lower pressing frame 307 is pushed from the lower mold plate 209 by the first electric cylinder 306. The upper mold plate 308 is moved downward, and the upper mold on the lower end surface of the upper mold plate 308 is pressed into the sole mold 210 in a one-to-one correspondence, so that the rubber inside the sole mold 210 is compacted to form a certain shape. During the pressing process, the excess rubber liquid will be squeezed out from the guide groove 212 and flow from the recovery hole 213 to the collecting funnel 107 below, so that the excess rubber is recovered and the raw materials are saved. Then the sole is cooled. After molding, there may be residual rubber liquid in the guide grooves 212 on both sides of the sole to form solids. However, compared with the traditional production mode, a circle of mold line will be formed around the sole, which is more material-saving, and cutting and grinding will be more convenient.

[0059] After the sole is formed, the upper template 308 is lifted and moved to the rightmost end. At this time, the motor B206 drives the bidirectional screw 207 to rotate so that the side fixing rods 204 on both sides are pulled out to unlock. The motor A202 drives the rotating block 203 to rotate, thereby driving the lower mold plate 209 of the sole to rotate 180 degrees so that the sole mold 210 faces downward and the ejector frame 214 faces upward. Then, the motor D402 drives the transport screw 403 to rotate to drive the sliding block 404 and the sliding frame 405 to move. The sliding frame 405 05 drives the conveyor belt 406 to move to the left between the collecting funnel 107 and the lower mold plate 209 of the sole; at this time, the motor C303 continues to drive the gear 304 to move the upper mold plate 308 to the top of the ejection frame 214, and the first electric cylinder 306 pushes the upper mold plate 308 to press the ejection frame 214 downward, so that the small rod of the ejection frame 214 extends from the ejection hole 211 to push out the molded sole in the sole mold 210, and the sole will fall to the top of the waiting conveyor belt 406 below, completing the automatic demoulding of the sole;

[0060] Next, the motor D402 drives the transport lead screw 403, which in turn drives the slider 404, the sliding frame 405, and the conveyor belt 406 to move to the right and return to the original position. Then, the conveyor belt 406 starts to move the soles on it to the right. Under the action of the limit plate 410, the soles will automatically line up in three rows. When the first row of soles moves to directly below the rectangular plate 409, the second electric cylinder 408 pushes the rectangular plate 409, which drives the bracket 501 to move downward, causing the positioning rod 502 to press on both ends of the sole. The position of the excess rubber on the sole is identified by the camera under the cutting knife 509. The motor E503 drives the slider 504 to move, which drives the cutting knife 509 to move to the specified position. The third electric cylinder 505 pushes the cutting knife 509 downward to cut off the excess rubber on both sides of the sole. Then, the motor E503 continues to drive the slider 504 to move, causing the grinding motor 507 to move to the cutting position. Then, the third electric cylinder 505 presses down on the plate of the grinding motor 507, and the two grinding motors 507 start to drive the grinding heads 508 on both sides to rotate and grind the cutting positions on both sides of the sole. After grinding, the sides of the sole are smooth and without marks. Next, the second electric cylinder 408 raises the grinding part 5. Then, the conveyor belt 406 starts to convey the first row of soles into the finished product storage box 108. Then, the above operations are repeated until a batch of soles is completely processed. When performing the post-treatment work on the molded soles, the main body part 1, the lower mold part 2, and the upper mold part 3 work together to continue producing rubber soles. The two operations are carried out simultaneously, which improves the work efficiency. The patterns of the produced soles are more diverse, and there is no whole-circle mold joint line on the molded soles, making grinding more convenient and the produced soles more beautiful.
