Description
Technical field
The utility model is related to a kind of positioning pin, specifically a kind of casting metal positioning pin.
Background technology
In traditional multiple mould, there are one layer or more of flask joints, and during with case, flask joint is offhand
Positioning, or positioning it is inaccurate and caused by mould shift, cause to pour into a mould mistake.It is existing to use the upper and lower babinet of positioning pin pin joint, it is used for
Ensure that babinet corresponds to positioning, but due to individually placed, multilayer sandbox conjunction when the positioning pin in every two layers of sandbox puts sand in babinet
Perpendicular positioning and the precise angular positions that every layer of positioning pin is unable to ensure when case are uncontrollable, easily lead to after the completion of sandbox puts sand and deposit
In angular deviation, lead to not more casees can not mould assembling, and during putting sand, there are casting sands loosely to cause to loosen the hidden of deviation
Suffer from.
Invention content
In view of the above-mentioned problems, the utility model provides, one kind is simple in structure, can effectively ensure the angle positioning between more casees
Precision prevents from loosening deviation, improves the casting metal positioning pin of castability.
The technical solution adopted in the utility model is：A kind of casting metal positioning pin, including cydariform pin pipe and cylindricality axis pin,
Cydariform pin pipe be externally provided with three or more along its axial circumferentially uniformly distributed anti-rotation blocked ear, the upper and lower opening internal orifice of cydariform pin pipe in
The upper and lower limit block of connection line correspondences up and down is set, it is axially arranged with limiting slot for the outer periphery of cylindricality axis pin, and cylindricality axis pin is worn
It is connected in cydariform pin pipe and is limited through limiting slot and the cooperation of upper and lower limit block.
A kind of casting metal positioning pin, including cydariform pin pipe and cylindricality axis pin, cydariform pin pipe middle part drum organization outer diameter is most
Greatly, the upper and lower half of cydariform pin pipe exceptionally wall be equipped with three or more along its axial circumferentially uniformly distributed anti-rotation blocked ear,
The anti-rotation blocked ear of upper and lower half point shifts to install, on the upper and lower opening internal orifice of cydariform pin pipe built-in connection up and down line correspondences it is upper,
Lower limit block, it is axially arranged with limiting slot for the outer periphery of cylindricality axis pin, and cylindricality axis pin is connected in cydariform pin pipe and through limit
Slot is limited with the cooperation of upper and lower limit block.
The cydariform pin pipe and cylindricality axis pin are steel.
The utility model is placed on using cydariform pin pipe on sandbox die joint, when multilayer sandbox puts sand, the first cydariform pin pipe
Lower half portion is placed in the first sandbox, and cydariform pin pipe top half is placed in the second sandbox, and cylindricality axis pin passes through limiting slot and drum
The limited block limit of shape pin pipe upper and lower opening, which is worn, to be connect, and passes through the second sandbox by elongated cylindricality axis pin, second is connect in upper wear again
Cydariform pin pipe, completes the positioning of third sandbox and the second sandbox, and the second cydariform pin pipe is placed in third sandbox, as stated above may be used
Complete molding, parting, the mould assembling of multilayer sandbox, it is ensured that positioning accuracy, in conjunction with cydariform pin pipe in upper and lower two sandbox of die joint
Anti-rotation blocked ear stagger setting effectively avoids the rotation of cydariform pin pipe, cylindricality axis pin from limiting grafting with cydariform pin pipe, effectively avoid column
Shape axis pin loosens, and integrally further increases positioning accuracy.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model usage state diagram.
In figure：Cydariform pin pipe 1,11, upper limit blocked ear 2, lower limit blocked ear 3, upper limit block 4, lower limit block 5, column

Specific implementation mode
It is described further below in conjunction with attached drawing.
Shown in Fig. 1：A kind of casting metal positioning pin, including cydariform pin pipe 1 and cylindricality axis pin 6, cydariform pin pipe middle part cydariform
Structure largest outside diameter, the upper and lower half exceptionally wall of cydariform pin pipe are equipped with three or more axial circumferentially uniformly distributed along it
Upper and lower anti-rotation blocked ear 2,3, upper and lower anti-rotation blocked ear shifts to install, straight line above and below built-in connection on the upper and lower opening internal orifice of cydariform pin pipe
Corresponding upper and lower limit block 4,5, cylindrical pin, it is axially arranged with limiting slot 7 for 6 outer periphery, and cylindricality axis pin is connected to drum pin
It is limited in pipe and through limiting slot and the cooperation of upper and lower limit block.In use, the first cydariform pin pipe 1 is placed in the first and second sandbox 8,9
Die joint, the second cydariform pin pipe 11 are placed in second and third sandbox 9,10 die joints, and die joint is that the cydariform diameter of cydariform pin pipe is maximum
Place, the first sandbox 8 are placed in the first cydariform pin pipe 1 after putting sand, make 8 die joint of the first sandbox, put the second sandbox 9, put sand, cylindricality
Axis pin 6, which is worn, connects the first cydariform pin pipe 1, completes to be placed in the second cydariform pin pipe 11 after the second sandbox puts sand, the second cydariform pin pipe 11 is worn
It is connected on cylindricality axis pin 6, makes 9 die joint of the second sandbox, put the completion third sandbox of third sandbox 10 and put sand, multilayer sandbox
Positioning, parting precision are high, and it is accurate to be conducive to mould assembling.
