Description

Technical Field

[0001] This utility model relates to the field of pouring cup processing technology, and in particular to a flanged pouring cup forming mold. Background Technology

[0002] The pouring cup is a crucial component in the casting process, receiving molten metal and guiding it into the sprue. Currently, the widely used funnel-shaped pouring cups typically have a flat outer surface at the inlet without a flange. While these traditional pouring cups can be stably produced using conventional molds and meet the basic casting requirements of most castings, producing pouring cups with flanges using traditional molds results in insufficient forming accuracy at the flange position. Furthermore, traditional molds lack suitable forming units designed for flange structures, leading to mold incompatibility. Therefore, we propose a flanged pouring cup forming mold to address these issues. Utility Model Content

[0003] This utility model addresses the shortcomings of traditional molds in the prior art, which are unable to adapt to the design of molding units suitable for the flange structure, by providing a flanged gating cup molding mold.

[0004] This utility model is achieved through the following technical solution: A flanged sprue cup forming mold includes a transfer mold and a forming mold, with a forming cavity between the transfer mold and the forming mold. The top of the transfer mold protrudes upward to form a boss, which is adapted to the bottom structure of the flanged sprue cup. A suction component is provided between the top of the transfer mold and the forming mold to restrict the outer side of the flanged sprue cup.

[0005] In a preferred embodiment of the present invention, the suction edge assembly is a first suction edge, the inner wall of the first suction edge is inclined from top to bottom outward, and the first suction edge is snapped onto the top of the transfer mold. The outer side of the top of the transfer mold is provided with a stepped surface adapted to the first suction edge, and the inclined arrangement facilitates the removal of the first suction edge during demolding.

[0006] In a preferred embodiment of the present invention, the suction edge assembly includes a second suction edge and a support ring. The support ring is installed at the bottom of the forming mold and is located on the upper surface of the second suction edge. The inner wall of the second suction edge is inclined from top to bottom outward, and the second suction edge is snapped onto the top of the transfer mold. The outer side of the top of the transfer mold is provided with a stepped surface that matches the second suction edge and is inclined to facilitate the removal of the second suction edge.

[0007] In a preferred embodiment of the present invention, threaded holes for connection are provided at the edge of the molding mold and on the first suction frame and the second suction frame, for connecting the first suction frame or the second suction frame to the molding mold.

[0008] In a preferred embodiment of this utility model, the thickness of the support ring is 1-1.5:1 to the thickness of the molding cavity. The support ring facilitates demolding after the pouring cup is cast. Support rings that are too thick or too thin are unlikely to facilitate demolding.

[0009] The beneficial effects of this utility model are: This invention, through the cooperation of the boss at the top of the transfer mold and the edge suction component, and the precise docking of the edge suction component and the forming mold, can form the flange structure of the pouring cup, ensuring the dimensional and positional accuracy of the flange after casting, thus meeting the forming requirements of the pouring cup.

[0012] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0013] Example 1: As Figure 1-3 The mold shown is a flanged sprue cup forming mold. In this embodiment, the flange on the outside of the liquid inlet of the sprue cup is flat. The system includes a transfer mold 1 and a forming mold 2. The top of the transfer mold 1 has a placement cavity, and the forming mold 2 is inserted into the placement cavity. A forming cavity 4 is formed between the transfer mold 1 and the forming mold 2. The top of the transfer mold 1 protrudes upward to form a boss 11, which is adapted to the bottom structure of the sprue cup flange. The boss 11 abuts against the bottom of the formed sprue cup. A suction component 3 is provided between the top of the transfer mold 1 and the forming mold 2. The suction component 3 is used to restrict the outer side of the sprue cup flange. In this embodiment, the suction edge assembly 3 is a first suction edge 31. The edge of the molding mold 2 and the first suction edge 31 are provided with threaded holes for connection. The first suction edge 31 and the molding mold 2 are connected by inserting bolts into the threaded holes. The inner wall of the first suction frame 31 is inclined from top to bottom outward, and the first suction frame 31 is snapped onto the top of the transfer mold 1. The top outer side of the transfer mold 1 is provided with a stepped surface that matches the first suction frame 31. The inclined setting facilitates the removal of the first suction frame 31 during demolding.

[0014] Example 2: Figure 4-6 The mold shown is a flanged sprue cup forming mold. In this embodiment, the flange on the outside of the liquid inlet of the sprue cup is "L" shaped. The system includes a transfer mold 1 and a forming mold 2. The top of the transfer mold 1 has a placement cavity, and the forming mold 2 is inserted into the placement cavity. A forming cavity 4 is formed between the transfer mold 1 and the forming mold 2. The top of the transfer mold 1 protrudes upward to form a boss 11, which is adapted to the bottom structure of the sprue cup flange. The boss 11 abuts against the bottom of the formed sprue cup. A suction component 3 is provided between the top of the transfer mold 1 and the forming mold 2. The suction component 3 is used to restrict the outer side of the sprue cup flange. In this embodiment, the suction edge assembly 3 includes a second suction frame 32 and a support ring 321. The edge of the molding mold 2 and the second suction frame 32 are provided with threaded holes for connection. The second suction frame 32 and the molding mold 2 are connected by inserting bolts into the threaded holes. The support ring 321 is installed at the bottom of the forming mold 2 and is located on the upper surface of the second suction frame 32. The inner wall of the second suction frame 32 is inclined from top to bottom and outward. The second suction frame 32 is snapped onto the top of the transfer mold 1. The outer side of the top of the transfer mold 1 is provided with a stepped surface that matches the second suction frame 32 and is set in an inclined shape to facilitate the removal of the second suction frame 32.

[0015] Secondly, the thickness of the support ring 321 is 1-1.5:1 to the thickness of the molding cavity 4. The support ring 321 is designed to facilitate demolding after the pouring cup is cast. Support rings 321 that are too thick or too thin will not be able to facilitate demolding.

[0016] During use, molten metal is poured into transfer mold 1, and the connected forming mold 2 and suction component 3 are placed into transfer mold 1 to squeeze the molten metal. At the same time, suction component 3 is snapped onto transfer mold 1 to fix it. After the molten metal cools, a pouring cup is formed in forming cavity 4.
