Description

Technical Field

[0001] This utility model relates to the field of marine pipe fittings processing, and in particular to a demolding mechanism for marine pipe fittings processing molds. Background Technology

[0002] Centrifugal cast pipe is a type of pipe produced using centrifugal casting. It has high strength and toughness and can remain stable under high pressure and stress. It is often used as a mold in marine pipe fitting processing.

[0003] A search revealed that CN222133393U discloses a demolding mechanism for large-diameter centrifugal cast pipes. The base frame has a cooling component fixedly connected inside. The cooling component includes an annular water channel, an inlet pipe, and an outlet pipe. The inlet and outlet pipes are connected to an external water source and power source, so that external cooling water enters the annular water channel through the inlet pipe, then enters the outlet pipe through the annular water channel, and finally flows back to the external water source, thus repeatedly circulating to cool the cast pipe.

[0004] In practical use, the water in the water pipe exchanges heat with the cast pipe fittings to cool them down. However, since the water cannot be directly attached to the inside of the pipe, the actual cooling rate is slow, which affects the demolding efficiency of the pipe fittings. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a demolding mechanism for processing molds for marine pipe fittings.

[0006] The technical solution to achieve the purpose of this utility model is as follows: This utility model provides a demolding mechanism for processing molds for marine pipe fittings, including a base plate, a slide rail, an inner support moving part, and a spray assembly.

[0007] A slide rail is fixedly installed on the base plate, and an inner support moving component is slidably installed on the slide rail.

[0008] The inner support moving component includes a moving frame that is slidably mounted on a slide rail. A moving rod is fixedly mounted on the upper part of the moving frame. An inner support frame is fixedly mounted on the end of the moving rod away from the moving frame. Several cylinders are fixedly mounted around the inner support frame. An arc-shaped plate is fixedly mounted on the push rod end of the cylinder.

[0009] The lower part of the mobile frame is equipped with rotatable casters on both sides. The casters on both sides are connected by caster axles. The casters abut against the upper surface of the base plate. The output shaft of the mobile motor is connected to the caster axles through gear transmission.

[0010] The spray assembly includes a sprayer, which is fixedly mounted on a movable frame. The nozzle is fixedly mounted on the center of the inner support frame on the side away from the movable rod. The spraying direction is away from the inner support frame. The sprayer and the nozzle are connected by a spray pipe.

[0011] Furthermore, the spray assembly also includes a fan, which is fixedly installed between the inner support frame and the nozzle, with the fan's outlet located away from the inner support frame.

[0012] Furthermore, the spray nozzle is made of high-temperature resistant materials such as metal corrugated pipe.

[0013] Furthermore, the demolding mechanism also includes a support component, which includes a support frame fixedly mounted on the base plate. The upper part of the support frame is annular, and the diameter of the annular portion is larger than the diameter of the pipe to be demolded.

[0014] Furthermore, several rollers are evenly mounted on the circumference of the annular part of the support component. The upper surface of the rollers is higher than the inner surface of the arc-shaped part of the support frame, and the rotation axis of the rollers is parallel to the plane of the support frame.

[0015] Furthermore, the demolding mechanism also includes a protective ring frame, which is slidably mounted on the slide rail and has a through protective ring at the top. The diameter of the protective ring is larger than the diameter of the pipe to be demolded.

[0016] Furthermore, the protective ring frame is installed on the right side of the inner support moving component, and the two sides of the protective ring frame are respectively connected to the two sides of the inner support moving component by steel wire ropes; the two ends of the steel wire ropes are respectively fixed to the side of the inner support moving component and the corresponding side of the protective ring frame.

[0017] The beneficial effects of this utility model are as follows:

[0018] Firstly, the sprayed water mist absorbs a large amount of heat through vaporization. At the same time, the airflow blown by the fan carries away the air and vaporized water mist from the pipe and blows it out from the other side of the pipe. The cooling effect of water mist cooling and forced air cooling is better.

[0019] Secondly, the support components and protective rings work together, and during the demolding process, both remain at the two ends of the demolded pipe, effectively preventing the pipe from rolling and falling and injuring people. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 As shown in the figure, a demolding mechanism for a marine pipe fitting processing mold includes a base plate 1, a slide rail 2, an inner support moving part 3, a support part 4, a spray assembly 5, and a protective ring frame 6.

[0029] A slide rail 2 is fixedly installed on the base plate 1, and an inner support moving part 3 is slidably installed on the slide rail 2.

[0030] like Figures 1 to 3 As shown, the inner support moving component 3 includes a moving frame 30 that is slidably mounted on the slide rail 2. A moving rod 31 is fixedly mounted on the upper part of the moving frame 30. An inner support frame 32 is fixedly mounted on the end of the moving rod 31 away from the moving frame 30. Several cylinders 33 are fixedly mounted on the inner support frame 32. An arc-shaped plate 36 is fixedly mounted on the push rod end of the cylinder 33.

[0031] It should be noted that the overall shape of the inner support frame 32 is similar to that of the pipe fitting to be demolded. If the cross-section of the pipe fitting to be demolded is circular, the inner support frame 32 will be circular; if the cross-section of the pipe fitting to be demolded is rectangular, the inner support frame 32 will be rectangular, and the length-to-width ratio of the two rectangles will be the same. The cross-section of the inner support frame 32 is slightly smaller than that of the pipe fitting to be demolded, so that the moving rod 31 can drive the inner support frame 32, the cylinder 33, and the arc plate 36 to enter from one end of the pipe fitting to be demolded and clamp and fix the workpiece to be demolded from the inside.

[0032] Cylinder 33 is installed around the inner support frame 32. When cylinder 33 is activated, the push rod of cylinder 33 drives the arc plate 36 to fix the workpiece from the inside of the pipe to be demolded.

[0033] A mobile motor 34 is fixedly installed inside the mobile frame 30. Mobile wheels 35 are rotatably installed on both sides of the lower part of the mobile frame 30. The mobile wheels 35 on both sides are connected by a mobile wheel axle. The mobile wheels 35 abut against the upper end surface of the base plate 1. The output shaft of the mobile motor 34 is connected to the mobile wheel axle through gear transmission.

[0034] like Figure 1 , Figure 3 As shown, on the base plate 1, a support component 4 is fixedly installed on the right side of the slide rail 2. The support component 4 includes a support frame 40 fixedly installed on the base plate 1. The upper part of the support frame 40 is circular, and the diameter of the circular part is larger than the diameter of the pipe to be demolded. Several rollers 41 are evenly rotated around the circumference of the circular part of the support frame 40. The upper end surface of the rollers 41 is higher than the surface of the arc-shaped part of the support frame 40. The rotation axis of the rollers 41 is parallel to the plane of the support frame 40. In this way, when the demolded metal pipe slides on the support frame 40, the rollers 41 in the arc-shaped part will rotate, reducing the friction between the demolded pipe and the support frame 40 and providing a certain degree of protection for both. At the same time, the circular part of the support frame 40 can effectively prevent the demolded pipe from falling.

[0035] like Figure 1 , Figure 2 As shown, the spray assembly 5 includes a sprayer 51, which is fixedly mounted on the movable frame 30. The sprayer 51 and the nozzle 53 are connected by a spray pipe 52. The spray pipe 52 is made of a high-temperature resistant material such as a metal corrugated pipe, which can adapt to the high temperature inside the metal pipe to be demolded.

[0036] The spray assembly 5 also includes a fan 54, which is fixedly installed on the side of the inner support frame 32 away from the moving rod 31, and the air outlet of the fan 54 is on the side away from the inner support frame 32; the nozzle 53 is fixedly installed at the center of the air outlet of the fan 54, and the spray direction is away from the fan 54.

[0037] Before or during the demolding mechanism's operation, the sprayer 51 is started, and the nozzle 53 begins to spray water into the metal pipe to cool it down. The fine water mist can absorb the heat in the pipe and quickly vaporize. At the same time, the fan 54 is started. Under the blowing of the fan 54, the spray can be more uniform, and the airflow can blow the gaseous water out from the other end of the pipe along with the high-temperature air inside the pipe, improving the pipe's cooling efficiency.

[0038] like Figure 1 As shown, the protective ring frame 6 is slidably mounted on the slide rail 2. Its overall structure is similar to that of the support component 4. A through protective ring 61 is opened at the top. The protective ring 61 is a complete circle with a diameter larger than that of the pipe to be demolded, allowing the metal pipe to be demolded to pass through the protective ring 61.

[0039] The protective ring frame 6 is installed on the right side of the inner support moving part 3. The two sides of the protective ring frame 6 are respectively connected to the two sides of the inner support moving part 3 by steel wire rope 37. One end of the steel wire rope 37 is fixed to the side of the inner support moving part 3, and the other end of the steel wire rope 37 is fixed to the corresponding side of the protective ring frame 6.

[0040] During the demolding process, the pipe will pass through the protective ring 61 of the protective ring frame 6. The protective ring frame 6 and the support component 4 work together to prevent the pipe from falling and injuring people.

[0041] Specific working method: When the centrifugal casting pipe is completed and the pipe needs to be removed from the fixed mold, move the inner support moving part 3 and the protective ring frame 6 to the right side of the slide rail 2 near the support part 4, and insert the moving rod 31 into the pipe to be demolded. At this time, if the pipe temperature is high, start the sprayer 51. The water inside the sprayer 51 will enter the nozzle 53 through the spray pipe 52 and then be sprayed into the pipe, absorbing a large amount of heat and vaporizing. At the same time, start the fan 54, and a large amount of air and water vapor will be blown out from the other end of the pipe with the airflow. Once the temperature is suitable, cylinder 33 is activated. The push rod of cylinder 33 drives the arc plate 36 to move towards the pipe wall and clamps and fixes the pipe from the inside. Then, the moving motor 34 is activated, and the moving wheel 35 drives the inner support moving component 3 and the pipe to move to the left. The pipe passes through the support component 4 and the protective ring frame 6 in sequence. As the inner support moving component 3 moves to the left, the steel wire rope 37 is gradually pulled closer and drives the protective ring frame 6 to move to the left until the pipe is demolded. In this way, during the demolding process, the support component 4 and the protective ring frame 6 restrain the pipe at both ends to prevent the pipe from falling and injuring people.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
