Description

Technical Field

[0001] This utility model relates to the field of disassembly tooling technology, specifically a novel demolding tooling for through-wall sleeves. Background Technology

[0002] Through-wall bushings are important insulation and connection components. After being formed in a mold, they need to be removed from the mold; this process is called "demolding." Traditional demolding methods mostly rely on manual operation, such as using a hammer to strike the mold, forcibly prying it with a crowbar, or pulling it with simple lifting tools. These methods apply force unevenly and are difficult to control, easily causing stress concentration in the through-wall bushing, leading to cracks, scratches, or even scrapping. Secondly, rough demolding methods can also damage high-value molds, shortening their service life and increasing production costs. Furthermore, manual demolding is labor-intensive, inefficient, and poses certain safety hazards, failing to meet the high requirements of modern, large-scale production for product quality, production efficiency, and operational safety.

[0017] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The technical solutions of the present invention 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 invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process.

[0020] like Figure 1 and Figure 6As shown in the illustration, this application proposes a novel demolding fixture for through-wall sleeves, including a mold and a through-wall sleeve to be detached within the mold. Both the through-wall sleeve and the mold have threaded holes at their bottoms. In this embodiment, the demolding fixture includes a fixture frame 1, a pulling mechanism, and a mold positioning mechanism. The pulling mechanism and the mold positioning mechanism are coaxially arranged opposite each other on the fixture frame 1 and respectively fix the through-wall sleeve and the mold. During the pulling process, the pulling mechanism applies a pulling force to the through-wall sleeve. Since the mold is fixed to the mold positioning mechanism, the pulling force of the pulling mechanism separates the through-wall sleeve from the mold.

[0021] like Figure 1 As shown, the working frame 1 includes four legs and a top plate fixed to the top of the legs. A worktable 4 is provided below the working frame 1. A demolding space is formed between the top plate and the worktable 4. During operation, the through-wall sleeve and the mold are placed in the demolding space.

[0022] The extraction mechanism includes a hoist 2 mounted on the tooling frame 1 and a demolding component 3 mounted on the output end of the hoist 2; the hoist 2 is mounted on the top plate, and its output end extends through the top plate into the demolding space. Figure 2 As shown, the demolding component 3 includes a frame body that runs through the front and back, with fasteners at the bottom for fixing the through-wall sleeve. The top of the through-wall sleeve is fixed to the demolding component 3.

[0023] During implementation, the elevator 2 provides a straight upward mechanical pull to the demolding component 3. Since the mold is fixed on the mold positioning mechanism on the worktable 4, the demolding component 3 drives the through-wall sleeve to separate from the mold.

[0024] In addition, the framework such as Figure 2 As shown, a rectangular frame is preferred, but the assembly can also be other polygonal frames, such as triangles.

[0025] like Figure 2 As shown, the fasteners include bolts 6 that penetrate the frame and lock nuts 7 that are tightened at the connection between the bolts 6 and the frame. In practice, the bottom of the bolts 6 is tightened onto the through-wall sleeve, and the bolts 6 are fixed to the demolding component 3 by at least one lock nut 7, thereby fixing the through-wall sleeve and the demolding component 3.

[0026] like Figure 1 and Figure 3 , Figure 4 As shown, the mold positioning mechanism includes a retainer 5. During implementation, the mold is placed on the retainer 5 and fixed by the tightening member 12 passing through the mold's fixing hole. The retainer 5 is set on the worktable 4 and is positioned opposite to the demolding member 3. It should be noted that the first opening 10 is coaxial with the bolt 6 of the fastener.

[0027] like Figure 3 As shown, the upper part of the mounting base 5 has a placement groove 9 that matches the shape of the mold. During implementation, the mold is placed in the placement groove 9, and the bottom of the outer wall of the mold abuts against the circumferential wall of the placement groove 9 to prevent the mold from rotating during demolding. It should be noted that the mounting base 5 and the worktable 4 respectively have a first opening 10 and a second opening 11 for the tightening member 12 to pass through. When the mold is placed in the placement groove 9, the fixing hole of the mold is coaxial with the first opening 10 and the second opening 11, so that the tightening member 12 can be connected to the fixing hole of the mold, thereby fixing the mold and preventing the through-wall sleeve and the mold from rotating during the lifting of the through-wall sleeve.

[0028] like Figure 5 As shown, the tightening component 12 is a screw. During implementation, the tightening component 12 can be used to fix the mold by manually operating a wrench through the bottom to top through the card holder 5 below the workbench 4, or it can be driven by a lifting and rotating mechanism to automatically screw the tightening component 12 in and out of the fixed hole of the mold.

[0029] In one possible implementation of a lifting and rotating mechanism, such as Figure 4 As shown, the lifting and rotating mechanism is a locking component 8, which is located below the worktable 4 and drives the tightening component 12 to rotate in and out of the fixing hole of the mold.

[0030] For example, the lower locking member 8 includes a fixed frame 81, a platform 82, a lifting drive mechanism 84, and a rotating assembly. The tightening member 12 is mounted on the rotating assembly. The fixed frame 81 is fixed to the worktable 4. The platform 82 is located inside the fixed frame 81. Guide shafts 83 are provided on both sides of the platform 82, and the bottom of the guide shafts 83 penetrates through the fixed frame 81. The lifting drive mechanism 84 is fixed at both ends to the fixed frame 81 and the platform 82, respectively. The lifting drive mechanism 84 is an electric telescopic rod. In implementation, the lifting drive mechanism 84 advances or retracts, causing the platform 82 to rise or fall. At this time, the guide shafts 83 move on the fixed frame 81, assisting the platform 82 to rise or fall smoothly. When the platform 82 rises, it drives the tightening member 12 to rise. Under the rotation of the rotating assembly, the tightening member 12 rotates in the rising state and screws into the fixing hole of the mold, fixing the mold in the holder 5. When the through-wall sleeve separates from the mold, the lifting drive mechanism 84 retracts and the rotating assembly rotates in the opposite direction, causing the tightening member 12 to fall and disengage from the fixing hole of the mold.

[0031] like Figure 4As shown, the rotating assembly includes a housing 87 and an assembly shaft 88. The housing 87 is fixed to the platform 82. A main shaft 86 is rotatably connected to the inside of the housing 87. A drive mechanism 85, which is a servo motor, is provided on one side of the housing 87 to drive the main shaft 86 to rotate. The assembly shaft 88 is fixed to the main shaft 86 and has a cavity 89 at its top for placing the tightening component 12. In a preferred embodiment, after the tightening component 12 is placed in the cavity 89, a pressure cap is used to fix the tightening component 12 in the cavity 89. In practice, different tightening components 12 can be selected according to the model of the mold. For example, after removing the pressure cap, the tightening component 12 is replaced, and then the pressure cap is pressed onto the nut of the tightening component 12, and then the pressure cap is fixed with screws.

[0032] During operation, the drive mechanism 85 drives the spindle 86 to rotate. At this time, the assembly shaft 88 rotates synchronously with the spindle 86, causing the tightening member 12 to rotate in both directions by the assembly shaft 88 and the spindle 86.

[0033] For example, the cavity 89 is polygonal, and the bottom of the tightening member 12 is adapted to the cavity 89 to prevent the tightening member 12 from spinning within the cavity 89.

[0034] Furthermore, the lower locking component 8 also includes a guide nut 811 located below the worktable 4. The middle part of the tightening component 12 is screwed onto the guide nut 811, which further fixes the position of the tightening component 12 and guides it along the axis, ensuring that the tightening component 12 is not affected by the pulling force of the pulling mechanism and is not disengaged from the assembly shaft 88, and ensuring that the tightening component 12 moves vertically. Furthermore, a movable retaining sleeve 810 is fitted on the outer side of the guide nut 811. The movable retaining sleeve 810 is secured to the worktable 4, limiting the guide nut 811 and preventing it from rotating.

[0035] In addition, the bottom surface of the worktable 4 has a slot that matches the movable sleeve 810. An end cap for pressing the movable sleeve 810 is provided on the outside of the slot. The end cap is fixed to the worktable 4 with bolts, and the guide nut 811 and the movable sleeve 810 are fixed in the slot.

[0036] 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.
