Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of core mold demoulding, in particular to a composite material winding core mold demoulding device. Background Art
[0002] With the rapid development of materials science in my country, engine combustion chamber casings are now molded from fiber-reinforced resin-based composites. During the winding process, product performance largely depends on the quality of the core mold. Currently, core molds for winding products primarily include metal, stone, sand, and rubber, with sand, adhesive, and hollow glass microspheres being the most common materials used.
[0003] At present, most winding core molds are demoulded by manual knocking, which has a high labor intensity. It is easy to damage the sand core mold by knocking on the core mold surface or knocking on the mold after the core mold is lifted. The operation efficiency is low and the demoulding cost is high. Utility Model Content
[0004] The purpose of the utility model is to provide a composite material winding core mold demoulding device to solve the problems raised in the above background technology.
[0005] The top of described sliding panel also is provided with an end face wall that is provided with an end face wall of sliding panel, and the bottom of described sliding panel is provided with an end face wall that is provided with an interlocking groove.
[0006] Preferably, both ends of the threaded rod are rotatably connected to the bottom plate and the top plate respectively, there are two threaded rods and they are symmetrically distributed on both sides of the top plate, and the lifting plate is threadedly connected to the outer sides of the threaded rods through threaded holes.
[0007] Preferably, there are two worm wheels, which are symmetrically distributed on both sides of the worm, and the worm is meshed with the two worm wheels at the same time.
[0008] Preferably, the slide groove is a straight groove, the inside of the slide groove is slidably connected to the slide rod, the bottom of the slide rod passes through the limiting groove and is fixedly connected to the baffle, the limiting groove is an arc groove, the positions of the slide groove and the limiting groove are correspondingly distributed, and the inside of the limiting groove is slidably connected to the outside of the slide rod.
[0009] Preferably, the card block is movably engaged with the interior of the card slot.
[0010] Preferably, the outer side of the gear ring is meshed with the gear.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The utility model provides a top plate, a threaded rod, a worm gear, a worm, a lifting plate, a clamping block, a mounting frame and a push rod. After the mold passes through the through hole on the surface of the top plate, it abuts against the surface of the lifting plate. The worm is driven by a motor to make the worm gear and the threaded rod rotate synchronously, so that the lifting plate drives the mold to move downward, and the core mold inside the mold is ejected by the push rod, which solves the problem of manual knocking on the mold to make the core mold demolding time-consuming and labor-intensive, and also avoids the situation where the core mold is damaged by manual knocking.
[0013] The utility model also provides a lifting plate, a slide groove, a sliding rod, a movable plate, a clamping block, a gear ring and a rotating plate. The gear drives the gear ring and the rotating plate to rotate through the second motor. The sliding rod moves inside the slide groove through the limiting groove, so that the movable plate drives the clamping block to insert into the clamping groove, thereby fixing the mold on the surface of the lifting plate, preventing the lifting plate from moving downward and allowing the mold to move upward synchronously, thereby enhancing the demoulding effect of the core mold, reducing the difficulty of installing and fixing the mold, and improving the demoulding efficiency of the core mold.

The upper surface of the lifting plate 8 is connected and fixed to the motor 2 16 by bolts, and the output end of the motor 2 16 is welded and fixed to the gear 17. The upper surface of the bottom plate 1 is welded and fixed to the mounting bracket 18, and the upper surface of the mounting bracket 18 is welded and fixed to the ejector rod 19. A mold 20 is provided on the top of the top plate 3, a slot 21 is provided on the outside of the mold 20, and a core mold body 22 is provided inside the mold 20.
[0022] The two ends of the threaded rod 4 are rotatably connected to the bottom plate 1 and the top plate 3 respectively. There are two threaded rods 4 and they are symmetrically distributed on both sides of the top plate 3. The fixed plate 2 and the top plate 3 form a rectangular frame. The inner wall of the lifting plate 8 abuts against the side of the fixed plate 2. The lifting and lowering of the lifting plate 8 is limited by the fixed plates 2 on both sides to ensure that the lifting and lowering of the lifting plate 8 is more stable.
[0023] A circular through hole is provided on the top of the top plate 3 for the mold 20 to move up and down, and the lifting plate 8 is located below the top plate 3. When the mold 20 moves downward so that the core mold body 22 inside is ejected, the core mold body 22 is located in the circular through hole of the top plate 3. The top plate 3 limits the core mold body 22 to avoid the core mold body 22 being damaged due to tilting after demoulding. At the same time, it is also convenient for subsequent staff to take the demoulded core mold body 22.
[0024] There are two worm wheels 5 and they are symmetrically distributed on both sides of the worm 7. One end of the worm 7 is rotatably connected to the ear plate, and the ear plate is fixedly connected to the upper surface of the base plate 1. The worm 7 is meshed with the two worm wheels 5 at the same time.
[0025] A matching hole is provided in the center of the lifting plate 8, and a demoulding hole is provided at the bottom of the mold 20. The positions of the demoulding hole and the matching hole correspond to the number and position of the ejector pins 19, and the gear ring 13 and the rotating plate 14 are both annular, so as to prevent the ejector pins 19 from being blocked when the lifting plate 8 drives the mold 20 downward, causing the ejector pins 19 to be unable to be inserted into the demoulding hole at the bottom of the mold 20.
[0026] The chute 9 is a straight chute, the inside of the chute 9 is slidably connected to the slide bar 10, the bottom of the slide bar 10 passes through the limit groove 15 and is welded to the baffle, the limit groove 15 is an arc-shaped chute, the chute 9 and the limit groove 15 are correspondingly distributed, the inside of the limit groove 15 is slidably connected to the outside of the slide bar 10, the clamping block 12 is movably connected to the inside of the clamping groove 21, and the outside of the gear ring 13 is meshed with the gear 17.
[0027] Working principle: When in use, the staff passes the bottom end of the mold 20 through the circular through hole on the top plate 3 and contacts it with the upper surface of the lifting plate 8, and ensures that the demoulding hole at the bottom of the mold 20 and the matching hole on the surface of the lifting plate 8 are aligned with the push rod 19. The gear 17 drives the ring gear 13 to rotate through the motor 2 16, and further rotates the rotating plate 14, and pushes the slide rod 10 to move horizontally inside the slide groove 9 through the limiting groove 15, so that the movable plate 11 moves and inserts the block 12 into the card slot 21 to realize the installation and fixation of the mold 20. The worm 7 drives the threaded rod 4 and the worm wheel 5 to rotate synchronously through the motor 1 6. The lifting plate 8 drives the mold 20 to move downward through the rotation of the threaded rods 4 on both sides. In this process, the core mold body 22 is ejected from the inside of the mold 20 by the push rod 19 through the demoulding hole at the bottom of the mold 20, effectively reducing the difficulty of demoulding the core mold body 22.
