[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] As shown in the figure, a composite material cylinder demoulding device includes a cylinder mold 2, a launch cylinder 3 and an extension cylinder 8. The cylinder mold 2 is used to produce the launch cylinder 3. After the composite material launch cylinder 3 is laid and solidified, the launch cylinder 3 is sleeved on the outside of the cylinder mold 2. The extension cylinder 8 is used to support the demoulded launch cylinder 3. The cylinder mold 2 is placed horizontally, and the end of the cylinder mold 2 away from the extension cylinder 8 is fixed to the upper end of the mold fixing bracket 1. One end of the extension cylinder 8 is fixed to one end of the cylinder mold 2 by a flange, and the other end of the extension cylinder 8 is placed on the upper end of the extension cylinder fixing bracket 10.

[0029] The mold fixing bracket 1 and the extension tube fixing bracket 10 are each secured to the ground using anchor bolts. A speed-adjustable reduction motor 12 is mounted on the extension tube fixing bracket 10. The reduction motor 12 is connected to a rope reel 19 via a connector, powering the rope reel 19. A steel wire rope 7 is wound around the rope reel 19, the free end of which is secured to the end of the launch tube 3 near the extension tube 8. The axis of the rope reel 19 is perpendicular to the axis of the extension tube 8. A cylinder clamp 6 is secured to the end of the launch tube 3, to which the free end of the steel wire rope 7 is secured. A steel wire rope guide pulley 11, which mates with the steel wire rope 7, is secured to the side of the upper portion of the extension tube fixing bracket 10. Preferably, the extension direction of the steel wire rope 7 is in the same horizontal plane as the axis of the extension tube 8. The steel wire rope 7 applies the demolding force to the cylinder clamp 6.

[0030] The extension tube 8 increases the ejection space for the launch tube 3. Several silicone rubber pads 21 are distributed along the length of the extension tube 8 to support the launch tube 3. The silicone rubber pads 21 protrude from the extension tube 8 and are evenly spaced along the length of the extension tube 8. Several rollers 22 are fixed along the length of the extension tube 8 on the side opposite the silicone rubber pads 21, or in other words, at the bottom of the extension tube 8. The rollers 22 facilitate the ejection of the extension tube 8 from the launch tube 3. Several lifting rings 20 are also fixed above the extension tube 8 to lift the extension tube 8. The lifting rings 20 are symmetrically distributed at both ends of the extension tube 8, and are evenly spaced as needed on the extension tube 8 between the lifting rings 20 at both ends.

[0031] A plurality of connecting bolts 23 are provided on the extension tube 8 at one end fixed to the cylinder mold 2 , and the connecting bolts 23 are evenly spaced around the outer circumference of the extension tube 8 .

[0032] To ensure the support stability of the barrel mold 2 and the launch barrel 3, a movable barrel roller bracket 4 and a mold bracket 5 are provided below the barrel mold 2 and the launch barrel 3. The barrel roller bracket 4 is used to support the launch barrel 3. The bottom of the barrel roller bracket 4 is designed with rollers 22 that can move with the launch barrel 3. The top of the barrel roller bracket 4 is designed with a conforming roller 13 that cooperates with the launch barrel 3 and rolls with the launch barrel 3. The conforming roller 13 is located on the lifting platform, which is also equipped with a pressure sensor 14. The pressure sensor 14 is electrically connected to the pressure sensor display instrument 15, which displays the weight of the launch barrel 3 in real time.

[0033] The lower end of the lifting platform is a bracket lifting system 16. Operating the bracket lifting system 16 can realize the lifting of the lifting platform. The bracket lifting system 16 can be a gear transmission system with a screw nut structure, which transmits the rotation of the external gear to the rotation of the gear below the lifting platform, thereby converting it into the rotation of the nut structure connected to the gear, and becoming the linear motion of the lifting platform. In order to ensure the lifting stability of the lifting platform, the lower end of the lifting platform is provided with symmetrical lifting guide columns 18. The lifting guide columns 18 cooperate with the guide holes on the cylindrical roller bracket 4 to realize the guiding function of the lifting platform. Symmetrical lifting support legs 17 are fixed to the outside of both sides of the lower part of the cylindrical roller bracket 4. After the lifting support legs 17 are raised, the cylindrical roller bracket 4 can move. After the lifting support legs 17 are lowered to near the bottom surface, the rollers 22 of the cylindrical roller bracket 4 are lifted to leave the bottom surface, and then the cylindrical roller bracket 4 is fixed.

[0034] The mold bracket 5 is used to support the launch cylinder 3 and the cylinder mold 2. The mold bracket 5 can also be raised and lowered and moved. The side of the mold bracket 5 is also provided with a lifting support leg 17 to fix or release the mold bracket 5.

[0035] An extension tube bracket 9 is provided below the extension tube 8 to support the extension tube 8. The extension tube bracket 9 is used to prevent damage to the extension tube 8 caused by excessive force arm and stress concentration. The structure of the extension tube bracket 9 is similar to that of the cylinder roller bracket 4. The extension tube bracket 9 can also be raised and lowered. The side of the extension tube bracket 9 is designed with a lifting support leg 17.

[0036] Since the composite material cylinder is heated and pressurized in an autoclave for curing before demoulding, and the expansion coefficient of the composite material is smaller than that of the metal mold, after cooling, the composite material cylinder and the metal mold have been separated and a gap has been generated. Therefore, the demoulding force is greater than the friction between the weight of the composite material cylinder and the metal mold, and the launch cylinder 3 can be removed from the mold.

[0037] The demoulding method created by the present invention:

[0038] S1: First, hoist the cylinder mold 2 to be demoulded onto the mold fixing bracket 1 and the mold bracket 5, connect the extension tube 8 to the cylinder mold 2 through the flange using the connecting bolts 23, and fix the other end of the extension tube 8 to the extension tube fixing bracket 10;

[0039] S2: Push the extension cylinder bracket 9 under the extension cylinder 8 to support the extension cylinder 8, push the cylinder roller bracket 4 under the launching cylinder 3 to support the launching cylinder 3, lower the mold bracket 5 to fix the wire rope 7 and the cylinder clamp 6;

[0040] S3: Start the reduction motor 12 and apply a pulling force from slow to fast speed. At this time, the launching cylinder 3 will slowly come out of the cylinder mold 2;

[0041] S4: After the ejection cylinder 3 is 1 / 3 away from the mold, the cylinder roller bracket 4 is translated in the demoulding direction, the mold bracket 5 is moved to the position where the cylinder mold 2 leaks out, and the mold bracket 5 is adjusted to support the cylinder mold 2;

[0042] S5: After each time the launch cylinder 3 is pulled away from one end of the cylinder mold 2, the cylinder roller bracket 4, the mold bracket 5, and the extension cylinder bracket 9 are adjusted to move in stages with the launch cylinder 3 to prevent the mold from being subjected to concentrated force;

[0043] S6: After the launch barrel 3 is completely out of the barrel mold 2, the barrel roller bracket 4 is pulled out. At this time, under the action of gravity, the launch barrel 3 falls on the multiple silicone rubber pads 21 on the extension barrel 8, and then the connecting bolts 23 between the extension barrel 8 and the barrel mold 2 are removed;

[0044] S7: Hoist the lifting rings 20 at both ends of the extension tube 8, and hoist the extension tube 8 and the launch tube body 3 onto the ground bracket. Due to the multiple sets of rollers 22 designed at the bottom of the extension tube 8, the extension tube 8 can be pulled out of the launch tube body 3 to complete the demolding of the launch tube body 3.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
