Description

Lock connecting sheet investment casting tree assembling structure
Technical Field
The utility model relates to an investment casting technical field, in particular to tool to lock connection piece investment casting tree assembling structure.
Background
The investment casting is also called lost wax casting, and comprises the procedures of wax pressing, wax trimming, tree forming, slurry dipping, wax melting, molten metal casting, post-treatment and the like. Lost wax casting is a process in which a wax pattern for a part to be cast is made of wax, and then the wax pattern is coated with slurry, that is, a clay pattern. And after the mud mold is dried, putting the mud mold into hot water to melt the internal wax mold. And taking out the clay mold after the wax mold is melted, and roasting to form the ceramic mold. Once calcined. Generally, a pouring gate is left when a mud mould is manufactured, then molten metal is poured into the mud mould from the pouring gate, and after the mud mould is cooled, required parts are manufactured.
The connecting piece is a main accessory of a lock, the surface of a part is required to be smooth, the geometric shape is required to be accurate, the material is cast 304 stainless steel, and no casting defect is caused visually. The existing process scheme is that a double-fork die head is adopted for tree assembly, parts are transversely arranged, other processes are executed according to a normal process, through trial production, the phenomenon of casting shrinkage porosity with different degrees is found at two folding edges and corners of the parts, the rejection rate is high, and the scheme needs to be improved.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tool to lock connection piece investment casting tree group structure aims at improving current investment casting structure, improves the yield of product.
In order to achieve the purpose, the utility model provides a tool to lock connection piece investment casting tree structure of organizing, connection piece both sides limit symmetry is equipped with two hems, and investment casting tree of organizing includes a pouring basin, still include a plurality of with the perpendicular of pouring basin connection is watered, and is a plurality of erect and water and arrange in parallel, arbitrary erect water evenly be provided with along vertical direction symmetry a plurality of with the interior runner that the connection piece corresponds, the hem of connection piece is arranged along vertical direction and is set up, erect water with still add a row of wax way between the connection piece.
Preferably, the vertical pouring channel is provided in a square hollow rod structure.
Preferably, the number of the vertical pouring channels is three, and the three vertical pouring channels form a three-fork die head structure.
Preferably, the pouring cup is arranged above the vertical pouring gate, and the pouring cup and the middle vertical pouring gate are arranged along the same vertical direction.
Preferably, four ingates are correspondingly arranged in any vertical runner, and the four ingates are symmetrically arranged at two sides of the vertical runner.
Compared with the prior art, the beneficial effects of the utility model are that: the existing connecting piece investment casting tree-assembling structure is improved, the connecting piece folding edges are arranged (longitudinally arranged) along the vertical direction, the casting shrinkage porosity phenomenon is effectively avoided, the yield is greatly improved, and therefore the production cost is reduced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the structures shown in the drawings without creative efforts.
FIG. 1 is a schematic view of the structure of the connecting sheet of the present invention;
FIG. 2 is a schematic view of a tree-assembling structure of the investment casting of the present invention;
the objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.
Detailed Description
According to the structure of the lock connecting sheet 1 in the investment casting tree group, referring to fig. 1, two folding edges 11 are symmetrically arranged on two side edges of the connecting sheet 1, referring to fig. 2, the investment casting tree group comprises a sprue cup 2, and further comprises a plurality of vertical runners 3 connected with the sprue cup 2, wherein the vertical runners 3 are arranged in parallel, and are random, the vertical runners 3 are uniformly provided with a plurality of inner runners 4 corresponding to the connecting sheet 1 along the vertical direction, the folding edges 11 of the connecting sheet 1 are arranged along the vertical direction, and the vertical runners 3 are further provided with a wax discharge channel 5 between the connecting sheets 1.
It should be noted that, this embodiment has improved present connection piece 1 investment casting tree group structure, arranges (indulges the setting) connection piece 1 hem 11 along vertical direction, effectively avoids the casting shrinkage porosity phenomenon, and the molten steel pours into the shell in-process into, and annotates and flows steadily, and is provided with wax removal way 5, and the exhaust is unobstructed, is difficult for producing the defect in the foundry goods shaping process, has improved the yield greatly to will hang down manufacturing cost.
Further, the vertical pouring channel 3 is provided with a square hollow rod structure.
Further, the number of the vertical pouring channels 3 is three, and the three vertical pouring channels 3 form a three-fork die head structure.
Furthermore, the pouring cup 2 is arranged above the vertical pouring gate 3, the pouring cup 2 and the middle vertical pouring gate 3 are arranged in the same vertical direction, the pouring process conforms to the metal liquid flowing principle, the defect of insufficient pouring is avoided, and the rejection rate is further reduced.
Furthermore, four ingates 4 are correspondingly arranged in any vertical runner 3, and the four ingates 4 are symmetrically arranged at two sides of the vertical runner 3.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
