Abstract

The utility model relates to a metal mould capable of changing a metal core for casting metal balls, which comprises a core body, an upper metal mould and a lower metal mould. The utility model is composed of the core body and a mould which is composed of the upper metal mould and the lower metal mould which are buckled together. A path pouring opening is arranged on the upper part of the core body and the inner chamber of the core body is communicated with the spherical cavity of the upper metal mould and the lower mould by a flowing path. The utility model is characterized in that the core body is composed of an upper metal core and a lower metal core which are buckled and made of metal material. The inner chamber formed after buckling is the spherical cavity. The upper metal core and the lower metal core are connected with the upper metal mould and the lower metal mould by connecting pieces. The utility model has the advantages that the metal cores and the metal path pouring opening are adopted to be convenient for replacing, the labor and the drying devices for manufacturing sand cores are saved, the utilization ratio of molten metal is increased and the quality and the surface smoothness of the metal ball are improved.

Description

The casting metals ball is with replaceable metal-cored metal die

The utility model relates to a kind of mould, relates in particular to a kind of casting metals ball with replaceable metal-cored metal die.

The metal die of existing casting metals ball adopts the sand body core mostly on the market, sand body waters the road junction, pour into molten metal by watering the road junction during casting, molten metal is entered by the runner in the core, following metal pattern fastens the spherical cavity that the back forms, cooling back Metal Ball, but, adopt the Metal Ball surface of above-mentioned Mold Making to have sand grains, influence its fineness, and on, metal between following core is useless, many molten metals have been wasted, make the molten metal utilization rate not high, moreover making core need place and able-bodied laborer, also need drying plant, also strengthened production cost undoubtedly.

A kind of casting metals ball that the purpose of this utility model designs at existing weak point in the above-mentioned prior art just is with replaceable metal-cored metal die, this mould structure is reasonable, adopt metal-cored and metal waters the road junction, replaceable dismounting, improved the utilization rate of molten metal, the surface quality of Metal Ball also greatly improves.

The purpose of this utility model realizes by following measure: this mould comprise core body and around core body by last metal pattern, following metal pattern fastens the mould that forms and forms, watering the road junction is positioned at core body top and is communicated with the core body inner chamber, the core body inner chamber by a plurality of runners respectively with last metal pattern, following metal pattern fastens a plurality of spherical cavities connections that the back forms, wherein: core body is made by metal material, metal-cored fastening forms down, the inner chamber that fastens back formation is a spherical cavity, on, metal-cored by connector and last down, the corresponding connection of following metal pattern, by metal material make water the road junction be arranged on metal-cored on.

The connector that is used to connect metal-cored and metal pattern adopts the screw of convenient disassembly.

This mould in use, molten metal waters the road junction by metal and pours into, balling-up in the Metal Ball chamber of upper and lower metal-cored inflow mould, molten metal become solid-state after, beat metal and water after the road junction makes it break away from metal die, Metal Ball is taken out in die sinking, because upper and lower metal-cored cavity is a spherical cavity, upper and lower metal-cored formation also be a Metal Ball, upper and lower metal-cored can the replacing.

The advantage that the utility model is compared with prior art possessed is: the road junction has substituted the sand body core and sand body waters the road junction owing to watering with metal-cored and metal, saved and made required place, labour and the drying plant of core, reduced working strength of workers, improved the utilization rate of molten metal, bring up to present about 90% by original 70%, and the quality and the surface smoothness of Metal Ball all are improved, and upper and lower metal-cored and metal to water the road junction all replaceable, convenient disassembly.

Accompanying drawing is a structural front view of the present utility model.

The utility model is explained in detail below in conjunction with accompanying drawing: this mould comprise core body and around core body by last metal pattern (1), following metal pattern (2) fastens the mould that forms and forms, watering road junction (5) is positioned at core body top and is communicated with the core body inner chamber, the core body inner chamber by a plurality of runners (8) respectively with last metal pattern (1) (2), following metal pattern fastens a plurality of spherical cavities (6) connection that the back forms, wherein: core body is made by metal material, metal-cored (3) (4) fasten and form down, the inner chamber (7) that fastens back formation is a spherical cavity, on, metal-cored (3) (4) are by easy-to-dismount screw (9) and last down, the corresponding connection of following metal pattern (1) (2), by metal material make water the road junction be arranged on metal-cored on.

Claims

1, a kind of casting metals ball is with replaceable metal-cored metal die, it comprise core body and around core body by last metal pattern (1), following metal pattern (2) fastens the mould that forms and forms, watering road junction (5) is positioned at core body top and is communicated with the core body inner chamber, the core body inner chamber by a plurality of runners (8) respectively with last metal pattern (1), following metal pattern (2) fastens a plurality of spherical cavities (6) connection that the back forms, of the present utility model being characterised in that: core body is made by metal material, metal-cored (3) (4) fasten and form down, the inner chamber (7) that fastens back formation is a spherical cavity, on, metal-cored (3) (4) are by connector (9) and last down, the corresponding connection of following metal pattern (1) (2), the road junction (5) of watering that is made by metal material is arranged on metal-cored (3).

2, casting metals ball according to claim 1 is with replaceable metal-cored metal die, and it is characterized in that: upper and lower metal-cored (3) (4) are by easy-to-dismount screw (9) and corresponding connection of upper and lower metal pattern (1) (2).
