Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixed tooling technology, and in particular to a fixed tooling for dewaxing of investment casting mold shells. Background Technology
[0002] In the dewaxing process of investment casting, the pallet serves as a core auxiliary tooling, undertaking the crucial functions of shell transfer and dewaxing operation support. Currently available dewaxing pallets are designed and load-bearing-compatible primarily for small to medium-sized investment casting shells, meeting the basic load-bearing and positioning requirements of these shells during transfer before and after dewaxing, thus ensuring the smooth operation of the dewaxing process for small to medium-sized shells.
[0003] However, for large investment casting shells, due to their significantly higher weight compared to small and medium-sized shells, existing dewaxing trays designed for small and medium-sized shells lack effective fixing and limiting structures during dewaxing and transfer, failing to provide stable support for the large shells. Even slight shaking during transfer can easily cause stress concentration at the point of contact between the large shell and the tray due to its own weight, leading to shell breakage and damage. This not only affects production efficiency but also increases production costs. Therefore, this invention proposes a fixing fixture for dewaxing investment casting shells to solve the problems existing in the prior art. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a fixing fixture for dewaxing investment casting mold shells. This fixing fixture for dewaxing investment casting mold shells uses replaceable mesh side plates and is equipped with multiple fixing rods, realizing the fixing of mold shells of different specifications and shapes. This fixture is simple to operate, efficient, and can quickly fix the mold shells.
[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a fixing fixture for dewaxing of investment casting mold shells, including a mesh side plate and a tray, wherein the mesh side plate is provided on both sides of the tray, and the mesh side plate is provided with mesh holes, wherein the mesh holes are provided in multiple sets;
[0006] The mesh is used to insert fixing rods, and the fixing rods are arranged in multiple groups to fix the shell.
[0007] A further improvement is that a reinforcing rib is provided at the middle position of the outer side of the mesh side plate, and the reinforcing rib is welded to the mesh side plate.
[0008] A further improvement is that the pallet includes a side plate and a bottom plate, the side plates are provided in two sets, and the two sets of side plates are respectively provided on both sides of the bottom plate, the bottom plate is provided with bottom holes, and there are multiple sets of bottom holes.
[0009] A further improvement is that: both ends of the side plate are provided with side blocks, and the side blocks are provided with mounting grooves inside, and the mesh side plate is adapted to the mounting grooves.
[0010] A further improvement is that the side plate and the bottom plate are welded together, and the side block is welded together with the side plate.
[0011] A further improvement is that: one end of the fixing rod is provided with an end head, and the other end of the fixing rod on the outside is provided with an external thread, and the diameter of the end head is larger than the diameter of the mesh.
[0012] A further improvement is that one end of the external thread on the fixing rod passes through the mesh and is fixed by a butterfly nut.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses components such as mesh side plates, fixing rods, and butterfly nuts to fix the shell. Multiple sets of fixing rods are inserted into the mesh to support the weight of the shell and fix its position. The butterfly nuts lock the fixing rods, ensuring that the shell will not be damaged or broken during the movement of the pallet.
[0015] 2. The mesh side plate of this utility model is installed by inserting into the mounting groove and the side plate of the tray, which makes it easy to replace mesh side plates of different specifications. With the help of multiple sets of flexible fixing rods that can be inserted into different meshes, this tooling can ensure that it is suitable for most product shells and facilitates the work.

[0023] Example 1
[0024] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a fixing fixture for dewaxing of investment casting mold shells, including a mesh side plate 1 and a tray. The mesh side plate 1 is provided on both sides of the tray, and the mesh side plate 1 is provided with mesh holes 2, which are provided in multiple sets.
[0025] The mesh 2 is used to insert fixing rods 3, and the fixing rods 3 are arranged in multiple groups to fix the shell 4. In use, the shell 4 is fixed by components such as the mesh side plate 1, fixing rods 3, and butterfly nuts 12. The multiple sets of fixing rods 3 are inserted into the mesh 2 to support the weight of the shell 4 and fix its position. The butterfly nuts 12 lock the fixing rods 3 in place, ensuring that the shell 4 will not be damaged or broken during the movement of the pallet.
[0026] A reinforcing rib 5 is provided at the middle position of the outer side of the mesh side plate 1, and the reinforcing rib 5 is welded to the mesh side plate 1. This allows the operator to hold the reinforcing rib 5 to insert or remove the mesh side plate 1 from the mounting groove 9.
[0027] The tray includes side plates 6 and a bottom plate 7. Two sets of side plates 6 are provided, each located on one side of the bottom plate 7. The bottom plate 7 has multiple sets of bottom holes. Side blocks 8 are provided at both ends of each side plate 6, and each side block 8 has an internal mounting groove 9. The mesh side plate 1 is adapted to the mounting groove 9. The mesh side plate 1 is installed by inserting into the mounting groove 9 and onto the side plate 6 of the tray, facilitating the replacement of mesh side plates 1 of different specifications. Combined with multiple sets of flexible fixing rods 3 that can be inserted into different mesh openings 2, this fixture ensures applicability to most product housings 4, facilitating work operations.
