Description

Technical Field

[0001] The utility model belongs to the technical field of mold casting vacuum fast melting furnace production, in particular to an adjustable tray tooling for loading a mold shell in a vacuum fast melting furnace. Background Art

[0002] Precision casting vacuum fast-melting furnace smelting involves rapidly melting a vacuum master alloy under induction current heating and then filling it into a mold shell. The melting process is divided into preheating, melting, and cooling stages. The vacuum bar stock requires a certain thickness of heat-transmitting layer between it and the induction coil. Due to the wide range of product structures and different assembly methods, the relative mold shell height varies, necessitating the design of mold shell trays of varying heights. Furthermore, the tooling design must consider the stability of the mold shell during placement and the emergency handling of steel leaks.

[0003] Therefore, the existing mold shell pallet tooling has many models, many spare parts, and poor versatility. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide an adjustable pallet tool for loading mold shells in vacuum fast melting furnaces, aiming to solve the technical problems of existing pallet tooling in vacuum fast melting processes, such as poor versatility. At the same time, this pallet tooling takes into account durability and convenience of use.

[0005] The utility model adopts the following technical solutions:

[0006] The adjustable tray tooling for loading the mold shell of the vacuum fast melting furnace comprises, from bottom to top, a bottom tray, an adjusting screw mechanism and an upper tray, wherein the adjusting screw mechanism has multiple groups, each group including a threaded sleeve, a threaded rod and a rotating connector, the threaded sleeve is fixed to the bottom tray, the top of the rotating connector is locked to the upper tray, the bottom of the threaded rod is screwed into the threaded sleeve, and the top is fixed to the bottom of the rotating connector.

[0007] Furthermore, a pair of operating planes are provided in the middle of the threaded rod.

[0008] Furthermore, the top of the threaded rod is a square handle, and an inner hole is opened on at least one surface of the square handle. The rotating connecting part includes an I-beam, and a square sleeve is rotatably connected to the bottom of the I-beam. The side wall of the square sleeve has small holes corresponding to the inner holes one by one. The square handle is located in the square sleeve, and the square handle and the square sleeve are fixed by screwing a screw through the small hole and screwing it into the inner hole.

[0009] Furthermore, the upper tray is provided with a countersunk groove corresponding to the adjusting screw mechanism one by one, and the bottom of the countersunk groove is a circular ring, which is locked to the top of the I-beam by passing a bolt through the circular ring, and the nut of the bolt is located in the countersunk groove.

[0010] The beneficial effects of the present invention are as follows: the pallet tooling of the present invention designs the original one-piece mold pallet tooling into a detachable structure consisting of a bottom pallet, an adjusting screw and an upper pallet, which has the following advantages: first, by adjusting the adjusting screw, it can adapt to molds of different types and heights, solving the problem of too many existing pallet tooling, many spare parts and poor versatility; secondly, the entire tooling is a detachable structure.

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0016] like Figure 1-3 As shown, the adjustable tray tooling for loading the mold shell of the vacuum fast melting furnace provided in this embodiment comprises, from bottom to top, a bottom tray 1, an adjusting screw mechanism 2 and an upper tray 3, wherein the adjusting screw mechanism 2 has multiple groups, each group including a threaded sleeve 4, a threaded rod 5, and a rotating connector 6, the threaded sleeve 4 is fixed to the bottom tray 1, the top of the rotating connector 6 is locked to the upper tray 3, the bottom of the threaded rod 5 is screwed into the threaded sleeve 4, and the top is fixed to the bottom of the rotating connector 6.

[0017] In this structure, the height of the upper tray is first adjusted by rotating the threaded rods. The diagram shows three sets of adjustment screw mechanisms, all of which are set. The adjustment screw mechanisms primarily consist of a threaded sleeve, a threaded rod, and a rotating connector. The threaded sleeve is fixed to the lower tray, and the threaded rod is screwed into the sleeve. The top of the threaded rod is rotatably connected to the bottom of the upper tray via a rotating connector. Specifically, a pair of operating flats 51 are located in the middle of the threaded rod 5 to facilitate rotation of the rods for height adjustment. The entire tooling assembly allows for a small amount of margin, and the three threaded rods need to rotate approximately synchronously. Alternatively, markings can be placed on the threaded sleeves, with the operating flats of the three rods aligned with the markings, and then rotated synchronously for a set number of turns. For the production of a batch of workpieces, a single height adjustment is sufficient, eliminating the need for repeated height adjustments. Consequently, only a small number of pallet tooling units are required, eliminating the need to prepare a specific pallet tooling unit for each product model. Adjusting the height can accommodate molds of varying types and heights, providing excellent versatility.

[0018] Of course, for the rotation adjustment of the threaded rods, you can also remove the upper tray first, then adjust the top heights of the three threaded rods to be consistent, and then install the upper tray.

[0019] The pallet fixture provided in this embodiment features a stable, detachable structure for easy maintenance. In the event of damage to components caused by a sudden breakout during the mold shell smelting process, only the damaged components can be replaced, resulting in a convenient, quick, and cost-effective solution. The upper tray structure can be designed with a hollowed-out bottom (hollowed-out in the illustration) or a non-hollowed-out bottom. This allows for both flattening the bottom of the mold shell with pads and filling the bottom of the upper tray with molten corundum sand, ensuring the mold shell will not tip over during both its ascent into the vacuum chamber and its descent after breaking vacuum, ensuring excellent stability.

[0020] Due to the large differences in product workpiece structures, different tree assembly methods, and differences in relative mold shell heights, the utility model designs a mold shell tray tooling that can adjust the height of the mold shell. At the same time, the tooling design also takes into account the stability of the mold shell placement process and the emergency treatment of steel leakage.

[0021] Combine Figure 3As shown, as a specific structure, the top of the threaded rod 5 is a square handle 52, and at least one surface of the square handle 52 has an inner hole 53. The rotating connecting member 6 includes an I-beam 61, and the bottom of the I-beam 61 is rotatably connected to a square sleeve 62. The side wall of the square sleeve 62 has a small hole 63 that corresponds one-to-one with the inner hole. The square handle 52 is located in the square sleeve 62, and the square handle 52 and the square sleeve 62 are fixed by screwing through the small hole into the inner hole. During installation, after adjusting the height of the threaded rod, the upper tray is lowered. After adjusting the angle of the three square sleeves, they are inserted into the corresponding square handles one by one, and finally the screws are screwed in to lock. When the height of the upper tray needs to be adjusted, the three threaded rods are rotated synchronously. If the adjustment range is large, the screws can be unscrewed, the upper tray can be removed, and then the height can be adjusted and the upper tray can be installed again according to the above method.

[0022] Furthermore, the upper tray 3 is provided with countersunk notches 31 corresponding to the adjustment screw mechanisms. The bottom of the countersunk notches 31 is a circular ring 32, which is screwed through the circular ring 32 and locked to the top of the I-beam 61, with the nuts of the bolts located within the countersunk notches 31. In this manner, the nuts at the tops of the bolts are located within the countersunk notches, which does not affect the placement of the formwork above. Furthermore, during installation, the rotating connectors can be fixed to the tops of the threaded rods, and then the upper tray can be aligned with the rotating connectors and screwed into the top of the I-beam to lock. Note that the threaded rods must be secured during this operation.

[0023] In summary, this device is a height-adjustable mold tray tooling used for loading molds. The entire device is detachable and easy to maintain. It is stable during the lifting process and is not easy to shake or fall off. The mold change is fast and can meet the use of investment casting vacuum fast melting furnaces.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
