Abstract
The utility model relates to a mold structure, in particular to a mould for manufacturing a valve needle, namely a precision forging mould for a valve needle hanging platform of an injection mould. An upper die holder is connected with a lower die holder through a guide post assembly, and a die is installed on the upper die holder. The precision forging mould is characterized in that the upper hanging platform processing position of the lower die holder is provided with a die moving guide rail, and an inlaid combined die is arranged on the die moving guide rail; a lateral positioning pin is arranged between the die moving guide rail and the inlaid combined die; a longitudinal positioning pin is arranged between the inlaid combined die and the lower die holder. The movable inlaid combined die moves to two sides before a product is put, the problem that a long valve needle cannot be installed in the die, and meanwhile a larger R angle and taper are avoided. A heating sensing coil can heat the valve needle hanging platform after being putting in the mould, and energy sources are effectively saved. Meanwhile, a clamp is used for preventing a main valve needle body from being stressed to be bent and deformed during hot forging.
Description
Technical field
The utility model relates to a kind of mould structure, particularly a kind of mould for the manufacture of needle.
Background technology
At present, manufacture field at injection mold industry needle, its batch production needle is all to adopt forming technique in advance, namely outside press equipment, product is heated, extrudes.Then, product is put into to matrix cavity, utilize preformed to extrude position and position forge hot, process product hanging platform position, then through turning, grinding, form.Because product is to utilize to extrude that position positions, hot-forging forming, in the Mold Making process, can be quickly installed in the forge hot matrix cavity for ease of the product after heating, its matrix cavity all is processed into the aperture with tapering, and bore is more much larger than product bar footpath.So just make product hanging platform root after forge hot and hanging platform bottom with larger R angle and tapering.Product after moulding can not meet the instructions for use of product.
In prior art, product usually adopts and first heats the mode of putting into afterwards matrix cavity, causes heat waste to a certain degree.In the process of processing slim product, the forge hot product can cause the distortion of product, reduces the formed product rate.
Summary of the invention
For addressing the above problem, this use is novel provides a kind of injection mold needle hanging platform finish forge mould, solve needle and can't be installed to the problem in die, avoid simultaneously the appearance of hanging platform and needle theme link position larger R angle and tapering, can make elongated (L>500mm, D is less than 10mm) the product mould of packing into, realize simultaneously saving the energy and avoiding product forge hot distortion.
For achieving the above object, the utility model provides a kind of injection mold needle hanging platform finish forge mould, upper bolster is connected by the guide pillar assembly with die shoe, die is installed on upper bolster, on described die shoe, the hanging platform machining position is provided with the die moving guide rail, the die moving guide rail is provided with the inlaid type combination die, is provided with the located lateral pin between die moving guide rail and inlaid type combination die, between inlaid type combination die and die shoe, is provided with the longitudinal register pin.
Described located lateral pin hanging platform far away workspace end is downward-sloping, 10 °-20 ° of described angle of inclination and horizontal plane angles.
Described injection mold needle hanging platform finish forge mould also is provided with the heat induced circle, and the heat induced circle is between die moving guide rail and upper bolster.
Described injection mold needle hanging platform finish forge mould also is provided with clamping device, and clamp is by clamp contiguous block connecting clamp cylinder, die spacing die bottom surface 30mm-50mm.
The other temperature monitor that is provided with of described heat induced circle.
Use the utility model effect remarkable: movably the inlaid type combination die again product put into the forward direction both sides can before and after move, solve long needle and can't be installed to the problem in die, adopt and inlay the appearance that combined die can be avoided product larger R angle and tapering simultaneously, the heat induced coil realizes that product heats after putting into mould, effectively save the energy, use simultaneously clamp restriction needle main body stressed bending, distortion during forge hot.

The specific embodiment
Embodiment 1
As shown in Figure 2, it is a kind of that the utility model provides, a kind of injection mold needle hanging platform finish forge mould, upper bolster 1 is connected by guide pillar assembly 19 with die shoe 5, punch 3 is installed on upper bolster 1, and on described die shoe 5, the hanging platform machining position is provided with die moving guide rail 4, and die moving guide rail 4 is provided with inlaid type combination die 7, between die moving guide rail 4 and inlaid type combination die 7, be provided with located lateral pin 6, be provided with longitudinal register pin 13 between inlaid type combination die 7 and die shoe 5.It is downward-sloping that described located lateral pin 6 can make die 7 pull out rear end, and described angle of inclination and horizontal plane angle are 15 °.
By inlaid type combination die 7 from mould, pulling out, baffle plate 11 is spacing, located lateral pin 6 makes to inlay combined die 7 and becomes an angle of inclination 4 of die moving guide rails, put into product 12, to mold center, push away inlaid type combination die 7, under the correcting of die moving guide rail 4, inlaid type combination die 7 displacements, when encountering locating piece, cylinder 10 actions, longitudinal register pin 13 is inserted in inlaid type combination die 7, and inlaid type combination die 7 is under the effect of die moving guide rail 4, longitudinal register pin 13, located lateral pin 6, and restriction inlaid type combination die 7 moves.
Use the present embodiment, movably inlaid type combination die 7 is before and after product 12 is put into mould, and the movement before and after can carrying out, solve long needle and can't be installed to the problem in die, adopts simultaneously inlaid type combination die 7 to avoid the appearance of larger R angle and tapering.
