Example Embodiment

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in a variety of different ways defined and covered by the claims.

[0034] Such as Figure 2 to Figure 8 As shown, a high-precision casting casting process, the high-precision casting casting process uses the following hanging coating machine, the hanging coating machine includes a dipping bin 10 and a placing cage 20 placed in the dipping bin 10, the dipping bin 10 is The top is an open rectangular groove structure. The placement cage 20 includes a first grid plate 21 and a side plate 22 fixed on one side of the first grid plate 21. The other side of the first grid plate 21 is provided with a side plate 22 are parallel to the outer edges 23, above the first grid plate 21 are provided with multiple sets of partitioning mechanisms 25 from top to bottom; the partitioning mechanism 25 includes a second grid plate ...

Abstract

The invention relates to a high precision casting foundry technique uses a hanging machine. The hanging machine comprises a leaching cabin, wherein the leaching cabin is of a rectangular groove structure opened in the top, a placing cage is placed in the leaching cabin, fixed pulleys are mounted on the tops of the left and right sides of the leaching cabin, and traction devices are arranged on theouter walls of the left and right sides of the leaching cabin. The hanging machine further comprises a plurality of spraying devices arranged on the back surface of the leaching cabin. By matching the placing cage with the spraying devices, a wax pattern can be sprayed uniformly, and meanwhile, by arranging a separation mechanism, the placing space of the wax pattern is increased and a pluralityof wax patterns can be coated in a hanging manner at one time, so that the hanging efficiency of the wax pattern is improved. By matching the fixed pulleys with the traction mechanisms, the traction mechanisms are treaded manually to lift and pull the placing cage, so that the coating on the wax pattern can be drained off to wet the wax pattern uniformly, and it is convenient to take out the wet wax pattern and place a to-be-wetted wax pattern.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a high-precision casting casting process. Background technique [0002] Lost foam, also known as wax mold, is a commonly used casting method, and it is also a new process with nearly no margin and precise molding. This process does not require mold taking, no parting surface, and no sand core, so the casting has no flash or burr and draft angle, which reduces the dimensional error caused by the combination of cores, and is suitable for casting high-precision castings. Investment casting is mainly composed of mold manufacturing, wax mold manufacturing, shell mold manufacturing and subsequent drying, roasting, pouring, solidification and other processes; the main processes and processes in the shell making process are: 1. Degreasing and Degreasing; 2. Apply paint and sand on the module; 3. Dry and harden the mold shell; 4. Melt and lose the mold from the mold shell; 5. R...
