TECHNICAL FIELD
[0001] The utility model belongs to a kind of investment casting technical field, more specifically, it is particularly related to a kind of investment casting core. BACKGROUND
[0002] Investment casting usually refers to the pattern made of fusible material, coated with several layers of refractory material to form a shell, and then the pattern is melted out of the shell, so as to obtain a casting without parting surface, which can be filled with sand after high-temperature baking. Since the pattern is widely made of wax material, investment casting is often called "lost wax casting". The core is commonly known as "mud core" or "core". During casting, core sand made of raw sand and binder (sodium silicate, resin, etc.) is manually or mechanically (such as core blowing machine, core shooting machine, etc.) made in the core box. In metal casting, metal cores are often used and removed in time after the metal solidifies.
[0003] Based on the above, the present inventors found that the existing investment casting core mostly has no support point, and it is usually necessary to clamp the pouring opening with a clamping piece during pouring of metal water, which is relatively inconvenient.
[0004] Therefore, in view of the above, the existing structure and defects are improved, and an investment casting core is provided to achieve a more practical purpose. INVENTION CONTENTS

[0011] Further, the materials of the support column, pouring opening, clamping step, support plate, wax mold and connecting rod are all wax.
[0012] Further, several said circular grooves are equidistantly distributed on both sides of the support column.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] Through the cooperation of the support column, the pouring opening and the support plate, after the wax melting, the support plate can be placed on the horizontal surface stably, and then the metal water is poured, without using external tools, and when the support column is welded with multiple wax molds, the pouring opening is generally placed on the horizontal surface, and then welded, and the welding of the last row of wax molds can be more difficult due to position or space problems, the support column can be rotated and the support plate can be placed on the horizontal surface, so that the welding work is more convenient, through the above design, the stability during pouring of the metal water is improved, without the aid of external tools, so that the operation process is simplified, and the production efficiency is improved.
[0015] Through the cooperation of the support plate, the through groove one, the support column and the through groove two, the overall weight is reduced, so that the material is saved.
