Technical Field

[0001] The utility model relates to a wax tree module, in particular to a wax tree module for casting mold forming applied to the field of casting mold forming. Background Technique

[0002] Precision investment casting of wax patterns, also known as investment casting or lost-wax casting, is a casting method in which the casting to be made is first made into a model with wax material, and the model is welded to a sprue bar with the same material to form a module tree. A refractory coating is adhered to the surface of the module tree, and then refractory sand is sprayed. After it is dried and solidified, the module tree is heated to remove the wax material from the sprue to form a mold shell.

[0003] The specification of Chinese Patent CN220406994U discloses a wax module tree for an elongated valve body. The utility model has the following beneficial effects: after the wax module tree is dipped in slurry and dewaxed, the top gate wax pattern forms a top gate, the side gate wax pattern forms a side gate, and the elongated integral valve body wax pattern forms an elongated integral valve cavity; the pouring efficiency is high, the feeding effect is good, the air tightness of the finished product of the elongated integral valve is good, the yield of the finished product is high, and it is beneficial to reduce the production cost.

[0004] In the actual application process, the existing modules usually use wax lacing. When preparing the mold shell, the wax lacing is prone to looseness, resulting in the problem that molten steel is likely to leak at this place when pouring molten steel into the formed mold shell. When the wax tree module is connected to the hook, the hook is usually directly penetrated into the wax tree module. After being installed and fixed with the machine, the machine drives the hook and the wax tree module to perform various operations. Under the action of gravity, there may be a shaking phenomenon between the wax tree module and the hook, which may lead to the wax tree module falling off. Summary of the Utility Model

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that when installing the wax tree module, the hook is generally directly inserted into the wax tree module. After long-term use, under the action of gravity, there may be a shaking phenomenon between the wax tree module and the hook, which may lead to the wax tree module falling off.

[0006] To solve the above problems, the utility model provides a wax tree module for casting mold forming, which includes a base. A support rod is fixedly connected to the upper end of the base. Two L-shaped rods are fixedly connected to the outer surface of the base. A ceramic connecting piece is fixedly connected to the upper ends of the two L-shaped rods and the support rod. A plurality of mounting rods are fixedly connected to the front, rear, left and right ends of the L-shaped rod and the support rod. A wax mold is fixedly connected to one end of each two mounting rods away from each other. A limiting groove is formed in the outer surface of the base, and the limiting groove is located below the fixed rod. A fixing component is sleeved on the lower end of the base. The fixing component includes two fixing rings. The inner circumferential wall and the inner bottom wall of the fixing ring are respectively attached to the outer circumferential surface and the lower end of the base. A limiting ring is fixedly connected to the inner circumferential wall of the fixing ring. One end of each two corresponding limiting rings penetrates into the limiting groove. A fixing pipe is fixedly connected to the lower end of the fixing ring. The upper end of the fixing pipe sequentially penetrates through the fixing ring and the base in a threaded manner. Two mounting plates are fixedly connected to the lower end of the fixing ring. Two groups of corresponding mounting plates of the two fixing rings are connected by screws in a threaded manner.

[0007] In the above wax tree module for casting mold forming, when the mold shell for casting manufactured by using this module is poured with molten steel, it is not easy to flow out from the corresponding position of the ceramic connecting piece, thereby effectively improving the product yield and reducing the waste of molten steel. At the same time, a fixing component is arranged at the bottom of the wax tree module, so that the wax tree module is tightly connected with the hook, thereby effectively avoiding the wax tree module falling off during the operation process and effectively ensuring the stable formation of the mold shell.

[0008] As a further improvement of the present application, the two L-shaped rods are symmetrically distributed with respect to the central axis of the base, and the upper ends of the L-shaped rods and the support rod are on the same horizontal plane.

[0009] As a further improvement of the present application, the limiting ring is completely matched with the limiting groove. The lower end of the fixing ring is semicircular. One end of the two corresponding mounting plates is on the same horizontal plane as one end of the two corresponding fixing rings, and the corresponding surfaces of the two fixing rings are attached to each other.

[0010] As a further improvement of the present application, thread grooves are provided on both the inner wall and the outer circumferential surface of the fixing pipe, and threaded holes for cooperating with the fixing pipe are formed on the surfaces of the fixing ring and the base.

[0011] As another improvement of the present application, the base is frustum-shaped, and a fixed rod is fixedly connected to the lower end of the L-shaped rod. One end of each two corresponding fixed rods is fixedly connected to the outer surface of the base.

[0012] As another improvement of the present application, a positioning block is further fixedly connected to the lower end of the fixing ring. The positioning block is located below the fixing pipe, and one end of each two corresponding positioning blocks is attached to each other.

[0013] In summary, in the actual application process, by replacing the traditional wax connecting piece with a ceramic connecting piece, during the melting process of the wax, the ceramic connecting piece does not melt, so that the molten steel inside the module is not easy to flow out, thereby effectively improving the yield rate of the product and reducing the waste of molten steel. When connecting with the hook, two fixing rings can be sleeved on the base, so that the two mounting plates are attached to each other, the limiting ring is inserted into the limiting groove, and the two mounting plates are fixed by a screw rod, thereby limiting and fixing the base and the fixing ring. Then, the hook is threadedly connected with the fixing pipe, and the fixing pipe is screwed into the fixing ring and the base, so as to improve the stability between the hook and the wax tree module. After the wax tree module melts, the fixing component can also be recycled and reused, which is convenient for the staff to use. Description of the Drawings
