As shown in fig. 1-5, a core housing for preparing a fan base, comprising:
The mud core device comprises a frame 100, wherein a mud core shell 101 is movably arranged in the frame 100, a cavity with an opening at the upper end is arranged in the mud core shell 101, and a plurality of loose pieces 102 are arranged on the cavity wall of the cavity;
the closing plate 103, closing plate 103 is provided with a closing hole 104, closing plate 103 can be movably placed at the opening of the cavity and is propped against movable block 102, and closing plate 103 and core shell 101 are matched to form a cavity for preparing the core.
In this embodiment, the size of the closing hole 104 is smaller than the size of the opening at the upper end of the cavity, so as to form a closing portion on the core, and when the closing plate 103 is covered on the core casing 101, it cooperates with the core casing 101 to form a cavity for preparing the core with the closing portion; and when the closing plate 103 covers the core-in shell 101, the closing plate 103 can also prop against the upper end face of the movable block 102, so that the freedom degree of the movable block 102 in the vertical direction is limited, and the installation accuracy of the movable block 102 in the core-in shell 101 is ensured.
As shown in fig. 2, it is further preferable that a connection frame 105 is fixedly provided on the closing plate 103, and a chain structure 106 is provided on an outer peripheral surface of the connection frame 105.
In the embodiment, the closing-up plate 103 and the core-in shell 101 are separable, and in the core-in forming process, the closing-up plate 103 covers the core-in shell 101; after the clay core is formed, the closing plate 103 needs to be removed from the clay core shell 101, and due to the fact that the size of the closing plate 103 is large, the position of the closing plate 103 is conveniently moved, and therefore the connecting frame 105 with the chain structure 106 is added on the closing plate 103, and connection with a lifting appliance is facilitated.
Further preferably, a portion of the edge of the core casing 101 extends upward to form a positioning portion 107, and when the closing plate 103 is placed on the core casing 101, a portion of the outer circumferential surface of the closing plate 103 abuts against the positioning portion 107.
In this embodiment, in order to ensure the accuracy of the placement position of the closing plate 103 on the core-in shell 101, a positioning portion 107 is formed by extending up a part of the edge of the core-in shell 101, and the closing plate 103 is installed and positioned.
Further preferably, a reinforcing portion 108 is formed to extend upward at a part of the edge of the frame 100 against the positioning portion 107.
In this embodiment, since the core-in-clay shell 101 is made of a wood material, the protruding positioning portion 107 is likely to deform after long-term use to affect the positioning accuracy of the closing plate 103, so that the reinforcing portion 108 is added to the frame 100 to abut against the positioning portion 107, and the frame 100 is made of square steel, so that sufficient supporting strength can be provided.
As shown in fig. 4, further preferably, the closing plate 103 is provided with at least one extending hole 109, and a closing plate 110 is movably disposed in the extending hole 109.
In this embodiment, in order to ensure more compact filling of molding sand in the cavity, the necking plate 103 is provided with an extending hole 109, and an arm of an operator can extend into the cavity through the extending hole 109 to stir and press the molding sand in the cavity.
It should be noted that, the sealing plate 110 is integrally provided with a positioning plate 111, when the sealing plate 110 is inserted into the insertion hole 109, the positioning plate 111 abuts against the closing plate 103, and the lower end surface of the sealing plate 110 is flush with the lower end surface of the closing plate 103.
As shown in fig. 5, preferably, a multi-stage chamfer wall 112 is provided on the wall of the cavity, and when a plurality of the loose pieces 102 are placed on the wall, the loose pieces 102 are abutted against the partial chamfer wall 112 or the partial chamfer wall 112 is integrally provided on the loose pieces 102.
In this embodiment, in order to match the shape of the product and to facilitate the subsequent demolding, the corners of the cavity are set as chamfer angles, if the cavity walls at the chamfer angles are split and then combined together when the movable block 102 is installed, gaps are likely to occur at the connection positions on the chamfer angles, and the flatness of the formed clay core surface is affected, so in the present application, the chamfer angle walls 112 are integrally arranged on the cavity walls or integrally arranged on the movable block 102.
Preferably, the cavity is internally provided with a core bar 113 and a supporting column 114 movably arranged in the cavity, when the supporting column 114 is placed on the bottom wall of the cavity, the middle part of the core bar 113 is propped against the supporting column 114, and a distance is arranged between each part of the core bar 113 and the wall of the cavity.
In this embodiment, in order to increase the strength of the clay core, a core bar 113 is further disposed in the installation cavity, and the middle end of the core bar 113 abuts against the support column 114 to raise the core bar 113, so that a certain distance is left between each position of the core bar 113 and the inner wall of the cavity, the situation that the core bar 113 is exposed after the clay core is formed is avoided, and meanwhile, the situation that the surface of the clay core is damaged due to the fact that molding sand at part of the formed clay core is thinner is avoided; after the core is formed, the support columns 114 are removed and then filled with sand.
Preferably, the frame 100 is mounted with a vibration motor 115.
In the present embodiment, the molding sand used for preparing the core in the cavity can be sufficiently filled in the cavity by the vibration of the vibration motor 115, and the uniformity of filling the molding sand in the cavity can be improved.
Further preferably, the frame 100 is further provided with a supporting block 116, and an output shaft of the vibration motor 115 extends out of the housing of the vibration motor 115 to be rotatably connected with the supporting block 116.
In this embodiment, during the vibration using process of the vibration motor 115, a certain radial force is applied to the output shaft when the eccentric block rotates around the output shaft, and the output shaft may deviate and be damaged when the eccentric block is used for a long time.
Further preferably, the bottom of the cavity is obliquely arranged, so that the demoulding of the formed mud core is facilitated.
