[0036] It should be noted that, unless otherwise specified, all components in the present invention are components known in the prior art. For example, the launch tube adopts a known and commonly used launch tube.

[0037] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0038] like Figure 1 As shown, a horizontal launch tube demoulding device includes a launch tube 1, a traction device fixing frame 2, a movable core mold support 3 and a fixed core mold support 4.

[0039] The launch tube 1 is horizontally arranged by a launch tube supporting device 5 .

[0040] The traction device fixing frame 2, the fixed core mold support 4 and the movable core mold support 3 are arranged in sequence from far to near at the front of the launch tube 1.

[0041] The movable core mold support 3 and the fixed core mold support 4 can carry the core mold of the launch tube 1.

[0042] A connecting ring 6 is fixedly mounted on the rear of the launch tube 1. The connecting ring 6 is fixedly connected to a launch tube fixing device 7. The launch tube fixing device 7 is fixedly arranged on the ground.

[0043] The demoulding device of the horizontal launch tube of the utility model is demoulding by an external traction device. The external traction device 2 adopts a known and commonly used device, such as a traction hoist. The traction hoist demoulds the core mold through a traction rope.

[0044] When in use, the rear of the launch tube 1 is fixed, and only an external traction device is needed to pull the core mold out of the launch tube 1 through the traction device fixing frame, which enhances the convenience of demolding. During the demolding process, as the core mold is gradually pulled out, the core mold enters the fixed core mold support 3 and the mobile core mold support 4 in turn. Among them, the mobile core mold 4 carries the core mold and moves together, ensuring the stability of the core mold movement and protecting the core mold from damage.

[0045] As a preferred solution, Figure 2 As shown, the traction device fixing frame 2 is "L"-shaped, and a first reinforcing rib 201 is provided on the side of the traction device fixing frame 2 away from the launching tube 1; a traction bracket 202 capable of carrying the traction device is provided on the side of the traction device fixing frame 2 close to the launching tube 1.

[0046] According to conventional selection, a plurality of through holes are opened at the bottom of the traction device fixing frame 2, and it is fixedly installed on the horizontal ground by anchor bolts. It should be noted that the fixed core mold bracket 4, the launch tube support device 5 and the launch tube fixing device 7 can all be fixed to the ground in this way.

[0047] As a preferred solution, Figure 3 As shown, the movable core mold support 3 includes a first support seat 301, and movable wheels 302 are arranged at the four corners of the first support seat 301; the moving direction of all movable wheels 302 is the same as the core mold pulling direction.

[0049] Furthermore, if Figure 4 As shown, the fixed core mold support 4 includes a second support base 401 fixedly arranged on the ground;

[0050] A semicircular second support plate 402 is fixedly disposed on the second support seat 401 ; the specification of the second support plate 402 matches the core mold and is coaxially disposed with the core mold.

[0051] During the demoulding process, as the core mold gradually comes out, it enters the first support plate 303 and the second support plate 402 in turn; the second support plate 402 of the fixed core mold support 4 ensures that the core mold of the removed part does not fall due to gravity, and prevents a large axial deviation from occurring between the barrel of the launch tube 1 and the core mold.

[0052] As the core mold is pulled out, it enters the movable core mold support 3 when it reaches a certain length, and then the movable core mold support 3 moves with the core mold. The movable core mold support 3 and the fixed core mold support 4 jointly support the core mold until the core mold is completely pulled out.

[0053] As a preferred solution, Figure 5 As shown, the launch tube fixing device 7 includes a fixing plate 701, and a through hole 702 is opened on the fixing plate 701;

[0054] The fixing plate 701 is sleeved on the rear part of the launching tube 1 through the through hole 702 ; the fixing plate 701 is fixedly connected to the connecting ring 6 ; the fixing plate 701 is fixedly arranged on the ground through the fixing seat 703 .

[0055] Furthermore, a second reinforcing rib 704 is provided between the fixing plate 701 and the fixing seat 703 to enhance the overall strength of the launch tube fixing device 7 .

[0056] As a preferred solution, elastic pads 8 are provided on both the first support plate 303 and the second support plate 402;

[0057] The elastic pad 8 is covered with a flexible pad 9. During demoulding, the elastic pad 8 of the fixed core mold support 4 and the movable core mold support 3 adapts to the axis deviation between the core mold and the launch tube 1 caused by the change in the core mold posture to prevent the core mold from damaging the inside of the composite material launch tube; the flexible pad 9 of the fixed core mold support 4 and the movable core mold support 3 can be made of felt according to the conventional selection in the field to protect the outer surface of the core mold from damage.

[0058] Specifically, the launch tube support device 5 includes at least one support frame;

[0059] A third support plate is fixedly arranged on the support frame; the shape of the third support plate matches the launch tube 1.

[0060] Furthermore, the supporting device 5 includes two supporting frames, which are respectively arranged at the front and rear of the launch tube 1 to enhance the stability of the launch tube 1.
