Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wax pattern storage, in particular to a wax pattern storage device for investment casting. Background Art
[0002] Wax model is a common casting method. Investment casting mainly consists of mold manufacturing, wax model manufacturing, shell mold manufacturing and subsequent drying, roasting, pouring, solidification and other processes. The wax model is used to form the shape of the casting cavity. To obtain castings with high dimensional accuracy and surface finish, the wax model itself should first have high dimensional accuracy and surface finish. However, the factors that affect the dimensional accuracy of the wax model during the wax model manufacturing process are relatively complex, and there are many process parameters, so the dimensional accuracy of the wax model varies widely.
[0003] In the prior art, since the stored wax models mostly need to be transported during the storage process, and since the wax models themselves have high dimensional accuracy, some wax models are not fixed in the storage boxes during transportation, which may cause the wax models to collide during transportation and damage the wax model body, resulting in partial defects in the subsequently produced products. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model adopts the following technical solution to solve the technical problems: a wax mold storage device for investment casting comprises a storage box, the upper surface of the storage box is fixedly connected to a fixing rod, a cover plate is arranged around the fixing rod, the outer surface of the cover plate is fixedly connected to a rotating shaft, the outer surface of the rotating shaft is rotatably connected to a sliding block, a lifting rod is arranged above the sliding block, a storage box is arranged below the lifting rod, a positioning device is arranged on the outer surface of the storage box, a lifting device is arranged on the outer surface of the storage box, the inner surface of the sliding block is slidably connected to the outer surface of the fixing rod, the lower surface of the lifting rod is fixedly connected to the upper surface of the fixing rod, a rotating shaft is arranged on the cover plate, a sliding block is arranged on the rotating shaft to slide on the fixing rod, so as to facilitate the taking and putting of the wax mold, and the lifting rod facilitates the movement of the storage box.
[0005] The positioning device includes a fixing ring, the outer surface of which is provided with an air collecting airbag, the outer surface of which is fixedly connected to a ventilating pipe, the outer surface of which is fixedly connected to a pushing airbag, the outer surface of the fixing ring is fixedly connected to the inner surface of a storage box, the inner surface of the storage box is slidably connected to a push plate, the outer surface of the push plate is fixedly connected to a pulling bar, the outer surface of the pulling bar is provided with a fixing column, the outer surface of the pulling bar is fixedly connected to a pedal, the outer surface of the pedal is slidably connected to the inner surface of the storage box, the outer surface of the storage box is provided with a return spring, the outer surface of the return spring is fixedly connected to the outer surface of the storage box, because the push plate is squeezed by the telescopic rod, it is usually in a squeezed state, and the thrust of the telescopic rod on the push plate is greater than the thrust of the return spring on the air collecting airbag. The force of the airbag, so the airbag is usually in an expanded state, and when the pedal is pressed, the four storage plates are retracted. Since many wax models have round holes, after putting the wax model in, the wax model round holes are aligned with the positions of the round holes and placed to wrap the four storage plates. After releasing the pedal, the four storage plates open to generate thrust on the inner walls of the round holes of the wax model, thereby fixing the wax model. The outer surface of the airbag contacts the outer surface of the storage box, and the outer surface of the storage box is fixedly connected to the outer surface of the fixed column. The outer surface of the pedal is fixedly connected with a buckle, and by setting the buckle, four storage plate positions of different diameters can be set. For wax models without round holes, the internal storage plate positions can also be set by different descending positions of the pedal and then fixed by the buckle, thereby setting storage positions of different sizes for different wax models.
[0006] The cam is connected with the upper and lower surfaces of the storage box, and the outer surface of the storage box is connected with the outer surface of the storage box, and the outer surface of the storage box is connected with the outer surface of the storage box, and the outer surface of the storage box is connected with the outer surface of the fixed airbag. After the wax mold is placed in the storage box, the cam lifts the bottom of the wax mold, and the fixed airbag at the bottom provides a lifting force for the cam, so that the wax mold stored in the storage box can be reduced by the fixed airbag during the movement process to reduce the impact of the box on the wax mold and the scratches on the wax mold surface.
[0007] The beneficial effects of the utility model are as follows:
[0008] 1. The utility model sets a positioning device, and a fixing ring and an air collecting air bag are fixed inside the storage box. Due to the presence of a reset spring, the fixing block is pushed, so that the push-pull plate fixed on the fixing block moves, thereby driving the storage plate to move, and the storage plate contracts inward and squeezes the push air bag, pushing the air in the air bag through the vent pipe to send the air inside the air bag. Since the push plate is squeezed by the telescopic rod, it is usually squeezed, and the thrust of the telescopic rod on the push plate is greater than the force of the reset spring on the air collecting air bag, so the air collecting air bag is usually in an expanded state, and when the pedal is stepped on, the push plate is in an expanded state. In the state, the four storage plates are retracted. Since many wax models have round holes, after putting the wax model in, the wax model is placed and the round holes are aligned to wrap the four storage plates. After releasing the pedal, the four storage plates open to generate thrust on the inner wall of the round holes of the wax model, thereby fixing the wax model. By setting the buckles, the positions of four storage plates with different diameters can be set. For wax models without round holes, the internal storage plate positions can be set by different descending positions of the pedal and then fixed by buckles, thereby setting storage positions of different sizes for different wax models. The fixed storage plates can also play a positioning role.
[0009] 2. The utility model provides a lifting device. When in use, the position of the pedal is adjusted to make the pushing airbag larger or smaller. When it is larger, an outward thrust is generated on the fixed block, and when it is smaller, a reset spring generates an inward thrust on the fixed block. The push-pull plate fixed by the fixed block pulls the storage plate position. After the storage plate position is set and the wax mold is placed in, the lifting plate lifts the bottom of the wax mold, and the fixed airbag at the bottom provides the lifting force for the lifting plate, so that the wax mold stored in the storage box can reduce the impact of the box on the wax mold during the movement process through the fixed airbag during the transportation of the storage box, thereby reducing scratches on the surface of the wax mold.
[0010] 3. The utility model sets a fixed block. After the fixed block is pushed, the slider fixed on the fixed block is driven to move. When the slider moves, it drives one end of the sliding bar to move, and the other end of the sliding bar drives the rotating column wrapped around the sliding bar. The sliding bar has a certain elasticity, so when the storage plate moves outward, the sliding bar will rewind the rotating column. Since the barrier plate protects the position of the airbag below, a cavity is set. The movement of the storage plate requires a track. It will be difficult to clean up debris that enters the cavity. Therefore, a slider and a sliding bar are provided outside the surrounding range of the storage plate to prevent dust and other debris from entering the cavity. An inflated airbag is provided within the surrounding range of the storage plate to block the track, thereby avoiding difficulty in cleaning debris in the cavity. BRIEF DESCRIPTION OF THE DRAWINGS

The outer surface of the pedal 78 is in contact with the outer surface of the storage box 1, and the outer surface of the storage box 1 is fixedly connected to the outer surface of the fixing column 77. The outer surface of the pedal 78 is fixedly connected with a buckle 710. Due to the presence of the return spring 79, the fixed block 84 is pushed, so that the push-pull plate 83 fixed on the fixed block 84 moves, thereby driving the storage plate 82 to move. The storage plate 82 shrinks inward and squeezes the push airbag 74, pushing the air in the airbag 74 to send its own internal air into the air-collecting airbag 72 through the vent pipe 73. Since the push plate 75 is squeezed by the telescopic rod, it is usually in a squeezed state, and the thrust of the telescopic rod on the push plate 75 is greater than the force of the return spring 79 on the air-collecting airbag 72, the air-collecting airbag 72 is usually in an expanded state.

The outer surface of the lifting plate 89 is slidably connected with the inner surface of the storage plate 82, and the outer surface of the storage plate 82 contacts the outer surface of the fixed airbag 88. After the storage plate 82 is positioned and the wax mold is placed in, the lifting plate 89 lifts the bottom of the wax mold, and the fixed airbag 88 at the bottom provides a lifting force for the lifting plate 89, so that the wax mold stored inside the storage box 1 can reduce the impact of the box on the wax mold during the movement process through the fixed airbag 88 during the transportation of the storage box 1.
[0020] Working principle:
[0021] When in use, by setting the positioning device 7, a fixing ring 71 and an air collecting air bag 72 are fixed inside the storage box 1. Due to the presence of the return spring 79, the fixing block 84 is pushed, so that the push-pull plate 83 fixed on the fixing block 84 moves, thereby driving the storage plate 82 to move. The storage plate 82 contracts inward and squeezes the push air bag 74, pushing the air in the air bag 74 to send its own internal air into the air collecting air bag 72 through the vent pipe 73. When storage is needed, the cover plate 3 on the fixing rod 2 is opened, and the pedal 78 is stepped on. The pedal 78 presses down the pulling bar 76. Due to the presence of the fixing column 77, the direction of the force of the pulling bar 76 is changed, and the push plate 75 is pulled away from the surface of the pushing air bag 74. Since the push plate 75 is squeezed by the telescopic rod, it is usually in a squeezed state. The thrust of the telescopic rod on the push plate 75 is greater than the force of the return spring 79 on the air bag 72, so the air bag 72 is usually in an expanded state, and when the pedal 78 is pressed, the four storage plates 82 are in a contracted state. Since many wax molds have circular holes, after the wax mold is placed, the wax mold circular holes are aligned with the positions of the circular holes and the four storage plates 82 are placed to wrap the wax mold. After the pedal 78 is released, the four storage plates 82 are opened to generate thrust on the inner wall of the circular hole of the wax mold, thereby fixing the wax mold. By setting the buckle 710, the positions of four storage plates 82 of different diameters can be set. For wax molds without circular holes, the internal storage plate 82 position can be set by setting the different descending positions of the pedal 78 and then fixed by the buckle 710, thereby setting storage positions of different sizes for different wax molds.
[0022] By setting the lifting device 8, the position of the pedal 78 is stepped on during use, so that the pushing airbag 74 can be enlarged and reduced. If it is enlarged, an outward thrust is generated on the fixed block 84, and if it is reduced, the return spring 79 generates an inward thrust on the fixed block 84. The push-pull plate 83 fixed by the fixed block 84 pulls the position of the storage plate 82. After the storage plate 82 is set and the wax mold is placed in the position, the lifting plate 89 lifts the bottom of the wax mold, and the fixed airbag 88 at the bottom provides the lifting force for the lifting plate 89, so that the wax mold stored in the storage box 1 can reduce the impact of the box on the wax mold during the movement process through the fixed airbag 88 during the transportation of the storage box 1, thereby reducing scratches on the surface of the wax mold.
[0023] A rotating shaft 4 is set on the cover plate 3, and a sliding block 5 is set on the rotating shaft 4 to slide on the fixed rod 2, which is convenient for taking and putting in the wax model, and the lifting rod 6 is convenient for the movement of the storage box 1. When the wax model is put in and the storage plate 82 moves, the sliding block 85 fixed on the fixed block 84 is driven to move after the fixed block 84 is pushed. When the sliding block 85 moves, it drives one end of the sliding bar 86 to move, and the other end of the sliding bar 86 drives the rotating column 87 wrapped with the sliding bar 86. The sliding bar 86 has a certain elasticity, so when the storage plate 82 moves outward, the sliding bar 86 will rewind the rotating column 87. Since the blocking plate 81 protects the position of the airbag below, a cavity is set. The movement of the storage plate 82 requires a track. It will be difficult to clean up if debris enters the cavity. Therefore, there are sliders 85 and sliding bars 86 outside the surrounding range of the storage plate 82 to prevent dust and other debris from entering the cavity, and there are inflated airbags within the surrounding range of the storage plate 82 to block the track to avoid cleaning difficulties.
