Description

Technical Field

[0002] When performing static pressure casting, a mold is needed. The existing static pressure line mold is large in size and mass, and it is troublesome to replace, which greatly reduces the work efficiency of workers. In addition, some existing static pressure line mold quick-change devices are inconvenient to clamp molds of different sizes, and are not practical.

[0003] After searching, a static pressure line mold quick-change device disclosed in the prior art (Announcement No.: CN215279842U) records that "the inner ring of the round tube is rotatably connected with three nuts, and the side surface of one of the nuts is transmission-connected to the side surface of the rotating shaft of the bidirectional motor through a belt, and the side surface of the nut is fixedly sleeved with a second bevel gear, and the second bevel gear is meshed with the first bevel gear. The inner side of the nut is threadedly connected with a screw, and one end of the screw extends to the outside of the round tube, and the other end of the screw is movably sleeved with a sleeve, and the side surface of the sleeve is movably connected to the side surface of the screw through a spring, and one end of the sleeve is fixedly connected with a clamping plate, and the inner side of the clamping plate is fixedly connected with a resistance block, and the outer side of the clamping plate is fixedly connected with a telescopic rod, and one end of the telescopic rod is fixedly connected to the inner side of the round tube. The device rotates the internal threaded tube clockwise through the bidirectional motor, and then the threaded rod is moved downward through the rectangular block. While the threaded rod is moved downward, the second bevel gear is rotated to drive the screw rod to move toward the central axis of the round tube, and then the mold is clamped and fixed by the clamping plate. The operation is simple and convenient, and it is convenient to clamp and fix molds of different sizes, and the practicality is better.

[0019] In this embodiment, when it is necessary to replace a different static pressure line mold body 13, the switch of the electromagnet 12 is first turned off, and the electromagnet 12 is powered off to stop the adsorption and fixation of the positioning component 3, so that the positioning component 3 is separated from the positioning groove 11 under the action of gravity and falls into the buffer groove 4, and then the restriction between the base 1 and the movable plate 9 is released, and then the switch of the main motor 16 is started, and the main motor 16 drives the moving screw 15 to rotate through the coupling, and the moving screw 15 pushes the moving plate 9, the mounting seat 8 and the mold body 13 to move synchronously through the screw-connected moving block 14, and then when the moving plate 9 drives the required mounting seat 8 and the mold body 13 to approach the hydraulic cylinder 10, the switch of the electromagnet 12 is turned on. , and then when the required mounting seat 8 and mold body 13 move to just above the hydraulic cylinder 10, the opening of the buffer groove 4 corresponds exactly to the positioning hole of the positioning groove 11, so the positioning component 3 can be quickly embedded in the positioning hole under the adsorption of the electromagnet 12, so that the base 1 and the movable plate 9 are fixed again, the switch of the main motor 16 is turned off, and the switch of the hydraulic cylinder 10 is started.

[0020] As a preferred embodiment, the base 1 is in the shape of an elongated strip, the cross-section formed by the combination of the base 1 and the movable groove is in the shape of a concave U-shaped structure, and the length of the movable groove is equal to the length of the base 1, and the sizes of the movable groove and the movable plate 9 are matched.

[0021] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The sizes of the moving groove and the moving plate 9 are matched, which can help enhance the stability of the moving plate 9 during movement and reduce the probability of positional displacement of the moving plate 9 and the mold body 13 along the width direction of the base 1 during movement.

At the same time, the cross-section formed by the combination of the movable plate 9 and the movable grooves is an E-shaped structure.

[0023] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The sizes of the movable groove and the mounting seat 8 are matched, which reduces the probability of the mounting seat 8 shaking in the movable groove. Then the upper surface of the movable plate 9 can be movably connected to the four groups of mounting seats 8 through the movable groove, and different mold bodies 13 can be installed in the mounting seat 8 according to actual needs.

[0025] In this embodiment, if Figure 2 , Figure 3 and Figure 4 The setting of the through-hole 6 enables the telescopic rod of the hydraulic cylinder 10 to extend into the corresponding movable groove through the through-hole 6, and then the telescopic rod of the hydraulic cylinder 10 can push the corresponding mounting seat 8 and the mold body 13 to move upward, so that the mold body 13 can perform corresponding linear reciprocating movements in the vertical plane.

[0027] In this embodiment, if Figure 2 , Figure 3 and Figure 4 The sizes of the positioning hole and the opening of the buffer groove 4 are adapted to each other, thereby facilitating the enhancement of the stability of the positioning component 3 after embedding, reducing the probability of accidental shaking between the limiting plate 2 and the movable plate 9, and thus enhancing the overall stability of the device after the mold body 13 is replaced.

[0028] As a preferred embodiment, a plurality of buffer grooves 4 are respectively formed on both sides of the moving plate 9 at equal intervals in parallel.
