Description

Technical Field

[0001] The invention relates to the field of injection molding equipment, and in particular to a molding device for a multifunctional high-pressure composite rubber hose. Background Art

[0002] When conducting oil extraction, maintenance, construction and other operations on oil wells in offshore oil fields, in order to obtain a stable construction environment, protect the safety of equipment and personnel, and facilitate construction operations, the staff will set up a temporary engineering structure - a dry work bunker cofferdam project, that is, to enclose a relatively dry construction area in the water. This area is called a dry work bunker, which is used to reduce the interference of waves and tides on construction, block waves and floating objects to a certain extent, and provide a waterless environment required for some operations.

[0003] The dry work warehouse cofferdam project mainly includes cofferdam walls, support systems and anti-seepage measures. The cofferdam wall can be divided into earth-rock cofferdam and steel sheet pile cofferdam according to different construction materials. The steel sheet pile cofferdam mainly uses steel sheet piles 101 to be inserted into the foundation by driving, vibration or static pressure to form a continuous wall to block water and soil. The steel sheet pile 101 is a steel section with a lock. The steel sheet piles 101 are connected to each other through the lock, and the lock space 102 is formed between the locks. In order to enhance the water-stopping performance of the cofferdam, it is usually necessary to seal the lock mouth internally. Traditional sealing materials include water-stop strips, sealing pastes, etc. However, there is currently a multifunctional high-pressure composite hose sealing method that uses a multifunctional high-pressure composite hose 103 for sealing. When sealing, a spraying and counterweight device is connected under the multifunctional high-pressure composite hose 103. After the spraying is in place once, the multifunctional high-pressure composite hose 103 is pressed to fix it in the lock mouth space 102. The positional relationship between the multifunctional high-pressure composite hose 103 and the lock mouth space 102 is shown in FIG. Figure 1 , Figure 2 As shown. The pressure-maintaining process and pressure monitoring device are arranged at the top of the cofferdam, which can monitor the pressure changes in the multifunctional high-pressure composite hose 103 in real time and replenish the pressure to ensure the water-stopping ability of the lock. After the ring beam is installed, the water injection pipeline of the multifunctional high-pressure composite hose 103 is changed to a grouting pipeline. Grout is first poured into the multifunctional high-pressure composite hose 103. After solidification, grout is poured into the lock through the grouting pipeline, and finally the cofferdam is sealed and water-stopped for a long time. This method is suitable for situations such as large sealing area and complex sealing environment on site, which can shorten the offshore operation time and reduce the operation risk to the greatest extent.

[0004] like Figure 3As shown, the multifunctional high-pressure composite hose 103 is a double-layer composite hose, including an inner tube 1031 made of polytetrafluoroethylene and an outer tube 1032 made of polyurethane. The existing multifunctional high-pressure composite hose molding method is a nested molding method, that is, the inner tube 1031 and the outer tube 1032 are produced separately, and then the inner tube 1031 is inserted into the outer tube 1032, and the inner tube 1031 and the outer tube 1032 are fixed together by heating, pressurizing or using an adhesive. It can be seen that the production process of this method is relatively cumbersome, including four main steps: inner tube molding, outer tube molding, inner tube and outer tube plugging, and inner tube and outer tube fixed connection. In addition, this method has high requirements on the dimensional accuracy of the inner tube 1031 and the outer tube 1032, otherwise it may cause poor matching, thereby affecting the quality of the pipe.

[0049] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.19As shown, at least one pusher 13 for pushing the processed multifunctional high-pressure composite hose 103 is installed at the bottom of the lower mold 202 and the top of the upper mold 201. The pusher 13 includes an arc-shaped pusher block 1301 for pushing the multifunctional high-pressure composite hose 103 and a third telescopic member 1302 for pushing the arc-shaped pusher block 1301 toward the direction of the inner tube 1031. The third telescopic member 1302 is vertically fixedly installed at the bottom of the lower mold 202 or the top of the upper mold 201. A guide column is vertically installed on the side of the arc-shaped pusher block 1301 away from the multifunctional high-pressure composite hose 103, a guide bracket is installed on the base frame 12, a hole for the guide column to pass through is opened on the guide bracket, and a third return spring 1303 is provided on the outer sleeve of the part of the guide column located between the arc-shaped pusher block 1301 and the guide bracket. A pressure plate is vertically installed on the top of the third telescopic member 1302, which can push the arc-shaped pushing block 1301 toward the direction of the inner tube 1031 when the telescopic end is shortened. When the mold 2 is in a closed state, the arc surface of the arc-shaped pushing block 1301 and the inner wall of the mold 2 are located on the same curved surface. After the mold 2 is opened, the telescopic end of the third telescopic member 1302 is shortened, and the pressure plate drives the arc-shaped pushing block 1301 to approach the multifunctional high-pressure composite hose 103, separating the multifunctional high-pressure composite hose 103 from the inner wall of the mold 2. The third reset spring 1303 is in a compressed state. After being pushed away, the telescopic end of the third telescopic member 1302 is extended, driving the arc-shaped pushing block 1301 away from the multifunctional high-pressure composite hose 103.

[0050] The working principle of the present invention is as follows: initially, the distance between the left clamp and the right clamp is the largest, the distance between the upper mold 201 and the lower mold 202 is the largest, the cooling component 7 is located at the far left, and the blanking inclined plate 10 is located at the rear.

[0051] Insert the right end of the inner tube 1031 in a horizontal state into the positioning hole 1201, and push the inner tube 1031 from left to right until it is completely located on the placement plate 601. The blocking claw 603 can block the inner tube 1031. At this time, the sheet-like rod cap of the capped sliding rod 606 contacts the bottom surface of the hollow cylinder 605 close to the blocking claw 603, and the second return spring 607 is in a naturally extended state.

[0052] The telescopic end of the first telescopic member 602 is gradually shortened, driving the placement plate 601 to move backward until the inner tube 1031 is located between the left clamping member and the right clamping member, and the output shaft of the fourth horizontal motor 505 starts to rotate, driving the seventh pulley 508 and the eighth pulley 509 to rotate synchronously in the same direction, the eighth pulley 509 drives the sixth pulley 507 to rotate through the fourth belt, the seventh pulley 508 drives the fifth pulley 506 to rotate through the third belt, the fifth pulley 506 drives the lead screw 502 on the right side to rotate, and the sixth pulley 507 drives the lead screw 502 on the left side to rotate. Because the spiral rotation directions of the lead screw 502 on the left side and the lead screw 502 on the right side are opposite, when the lead screw 502 on the left side and the lead screw 502 on the right side rotate synchronously in the same direction, the lead screw nut 503 on the right side and the lead screw nut 503 on the left side move toward each other synchronously, thereby driving the left clamping member and the right clamping member to move toward each other synchronously, and the distance is shortened.

[0053] As the left clamp and the right clamp gradually approach, the cone 305 gradually extends from the opening of the inner tube 1031 into the inner tube 1031, and the edge of the opening of the inner tube 1031 gradually contacts the adjustment block 302, driving the adjustment block 302 to slide in the second through hole and on the two small capped rods 303 of the small slide rod group in the direction away from the inner tube 1031, and the first return spring 304 is compressed, changing from a natural elongated state to a compressed state. The cone 305 can improve the concentricity of the inner tube 1031 and the left and right clamps, while the adjustment block 302 and the first return spring 304 provide abutment force to the inner tube 1031, so that the inner tube 1031 is firmly fixed and radial and / or axial movement is minimized. At this time, the inner tube 1031 has been fixed.

[0054] The telescopic end of the first telescopic member 602 gradually extends, driving the placement plate 601 to move forward. Since the inner tube 1031 has been fixed, the blocking claw 603 will be hindered by the inner tube 1031 when it moves forward with the placement plate 601. The two small vertical rods of the blocking claw 603 will rotate around the second small rotating shaft, and the capped sliding rod 606 will slide in the hollow cylinder 605 in the direction away from the blocking claw 603. The second return spring 607 is gradually compressed, and the small rotating block of the hollow cylinder 605 rotates around the first small rotating shaft. The top of the blocking claw 603 is in the same horizontal plane as the top of the placement plate 601 and is no longer hindered. The placement plate 601 continues to move forward. After the blocking claw 603 is no longer in contact with the inner tube 1031, when the second return spring 607 spontaneously returns from the compressed state to the natural extension state, the blocking claw 603 will return to the initial position. At this time, the next inner tube 1031 to be processed can be placed on the placement plate 601.

[0055] The output shaft of the second horizontal motor 401 starts to rotate, driving the first gear 406 and the second gear 407 to rotate synchronously in the same direction, and the first gear 406 is simultaneously meshed with the upper rack 404 on the right and the lower rack 405 on the right, and the second gear 407 is simultaneously meshed with the upper rack 404 on the left and the lower rack 405 on the left. Therefore, the upper rack 404 on the right and the lower rack 405 on the right move synchronously toward each other in the up and down directions, and the upper rack 404 on the left and the lower rack 405 on the left move synchronously toward each other in the up and down directions, thereby driving the upper mold 201 and the lower mold 202 to move synchronously toward each other through the C-shaped plate 403 and the three vertical connecting rods until the upper mold 201 and the lower mold 202 are completely closed, and the two ends of the inner tube 1031 extend from the left and right ends of the mold 2 respectively, and the retractable pipe gradually extends as the upper mold 201 gradually descends.

[0056] The heating belt is turned on, and polyurethane particles are added to the shell from the feed port. The motor is started, and the motor drives the spiral conveyor to rotate. The spiral conveyor gradually conveys the polyurethane fluid to the discharge port through rotation. After the polyurethane fluid flows out from the discharge port, it flows into the injection molding cavity along the retractable pipe. After the injection is completed, the motor is turned off and the polyurethane fluid is stopped from being conveyed to the injection molding cavity. The polyurethane fluid is gradually formed into an outer tube 1032 fixedly sleeved on the outside of the inner tube 1031 in the molding cavity. After the expected molding time is reached, the output shaft of the second horizontal motor 401 starts to rotate in the opposite direction, and the upper rack 404 on the right and the lower rack 405 on the right move synchronously in the up and down directions. The upper rack 404 on the left and the lower rack 405 on the left move synchronously in the up and down directions, thereby driving the upper mold 201 and the lower mold 202 to move synchronously in the opposite direction through the C-shaped plate 403 and the three vertical connecting rods until the upper mold 201 and the lower mold 202 are completely separated and return to the initial state.

[0057] The equipment for providing cold air starts to work, and produces cold air of suitable temperature for cooling. The cold air is input into the nozzle 702 through the pipeline. The nozzle 702 starts to spray cold air, and the third horizontal motor 801 is started. The output shaft of the third horizontal motor 801 starts to rotate, driving the fourth gear 804 to rotate. Because the fourth gear 804 is meshed with the horizontal rack 803, when the fourth gear 804 rotates, it can drive the third horizontal motor 801 and the nozzle mounting frame 701 to slide to the left on the second sheath and one of the horizontal square columns, so that the nozzle 702 slides to the left. By changing the rotation direction of the output shaft of the third horizontal motor 801, the nozzle 702 can slide to the right, thereby covering the processed multifunctional high The length of the composite hose 103 is compressed. At the same time, the output shaft of the first horizontal motor 901 starts to rotate, driving the third pulley 904 and the fourth pulley 905 to rotate synchronously in the same direction. The third pulley 904 drives the first pulley 902 to rotate through the first belt, and the first pulley 902 drives the horizontal rotating shaft 306 of the right clamping part to rotate. The fourth pulley 905 drives the second pulley 903 to rotate through the second belt, and the second pulley 903 drives the horizontal rotating shaft 306 of the left clamping part to rotate, thereby driving the two clamping joints to rotate synchronously in the same direction, thereby driving the processed multifunctional high-pressure composite hose 103 to rotate, so that the cold air can cover all parts of the outer surface of the multifunctional high-pressure composite hose 103. After the cooling is completed, the first horizontal motor 901 and the third horizontal motor 801 are turned off.

[0058] When the cooling device starts to work, the telescopic end of the second telescopic member 11 shortens, driving the material discharging inclined plate 10 to move forward until it completely covers the lower mold 202. After the cooling is completed, the output shaft of the fourth horizontal motor 505 starts to rotate in the opposite direction, driving the screw nut 503 on the right side and the screw nut 503 on the left side to move synchronously backward, thereby driving the left and right clamping parts to move synchronously backward and return to the initial position. The cone 305 gradually leaves the inner tube 1031, and the first return spring 304 returns from the compressed state to the natural extension state, so that the adjustment block 302 slides in the second through hole and on the two small capped rods 303 of the small slide rod group in the direction close to the inner tube 1031, gradually returning to the initial position, and the multifunctional high-pressure composite hose 103 loses its fixation, then falls onto the material discharging inclined plate 10, and rolls down to the finished product collection area along the material discharging inclined plate 10.

[0059] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above-mentioned embodiments, and various changes can be made thereto within the knowledge scope of ordinary technicians in this field.
