Embodiment Construction
[0025] refer to figure 1 , figure 2 , image 3 and Figure 4 As shown, the specific embodiment of the one-time molding manufacturing process of the inner heating riser of the present invention comprises the following steps:
[0026] a. Make inner mold tool 1, outer mold tool 2 and packing plate 3 according to the shape requirements of the riser;
[0027] b. Set the filler plate 3 into the inner mold 1 of the riser, and inject the heating material;
[0028] c. Remove the filler plate 3, replace it with the outer mold tool 2, and inject the insulation material;
[0029] d, demoulding the riser to obtain a wet riser;
[0030] e. Baking the wet riser once under high temperature conditions.
[0031] The step b is a process of manually injecting heat-generating material by a simple material injection device.
[0032] The step c is to complete the process of automatically injecting the thermal insulation material by the core making machine.
[0033] The step d is to separate...

The invention relates to a one-time forming manufacturing technology for an internal heat riser. The technology comprises following steps of manufacturing an inter-mould tool, an outer-mould tool and a filler plate according to the shape of the riser; nesting the filler plate into the inter-mould tool of the riser and injecting a heating material; taking the filler plate down, replacing the outer-mould tool and injecting a heat-insulating material; demoulding the riser to obtain a wet riser; and roasting the wet riser and forming in one time. The technology solves a problem that combination of the heating material and the heat-insulating material of the heat riser is not firm, and achieves the manufacturing technology of one-time forming of the heating material and the heat-insulating material. The technology is capable of guaranteeing fixed form and fixed quantity of the heating material, enhancing the strength of the riser body and guaranteeing safety in casting processes of the riser.
Description
technical field [0001] The invention relates to the field of casting, in particular to a one-time forming manufacturing process of an inner heating riser. Background technique [0002] In metal casting, generally according to the structural characteristics of the casting, risers are used for the thicker and larger parts of the casting and the hot node parts, so that the molten metal in the riser is used to feed the casting parts. In the production process of high-nickel and heat-resistant steel casting products such as exhaust pipes and turbine shells, in order to ensure the molding accuracy of casting blanks and improve the efficiency and automation of molten metal, sand cores have gradually been used in recent years to replace traditional manual casting. modeling. The use of risers has also transitioned from sand risers and thermal risers with general thermal insulation conditions to thermal insulation risers and internal heating risers. However, due to the different sha...
