Description
Technical field
The utility model is related to extrusion die fields, more particularly, to a kind of multi-step gear extrusion mold.
Background technology
Mold be in industrial production to be molded, be blow molded, squeeze out, the side such as die casting or forging forming, smelting, extruding, stretching
Method obtains the various moulds and tool of required product.In brief, mold is the tool for formed article, this tool by
Various parts are constituted, and different molds is made of different parts.It mainly by the change of physical state of the formed material come
Realize the processing of article shape.By molding material difference, mold can be divided into metal die and nonmetal mould.Metal mold
Tool be divided into for：Casting mould (non-ferrous metal die casting, steel casting) and forging mold etc..
Mold is classified by the processing technology of processing metal, there are commonly：Extrusion die, including blanking die, bending die, drawing
Mould, flange die, reducing die, forcer, bulging die, sizing die etc.；Forging die, including die forging forging die, upsetting die etc.；And it squeezes
Pressing mold and compression mod..
It produces a product in batches, designs and manufacture a kind of suitable mold and be produced into for improving production efficiency, saving
This is significant.Fig. 1 show a multi-step gear structure, and there is presently no one kind dedicated for producing the multi-step gear
Particular manufacturing craft.
Invention content
The technical problem to be solved by the utility model is to provide a kind of multi-step gear extrusion molds.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of multi-step gear extrusion mold,
Further include that a station squeezes mould body and two stations extruding mould body, a station squeezes including upper die holder and lower die holder
Mould body includes the first punch-pin and the first cavity plate, and first punch-pin is equipped with punch, and first cavity plate is equipped with the first punching
Hole, the punch lower end is cylindrical, and first punching includes upper and bottom section, in first punching
Part is cylindrical and is adapted with punch, and the first punching lower part is in odontoid；
It includes the second punch-pin and the second cavity plate that two stations, which squeeze mould body, and second punch-pin is equipped with upper first
Tooth socket, second cavity plate are equipped with the second punching, and second punching includes the second tooth socket and third tooth socket, and described the
Three tooth sockets are located at below the second tooth socket and the two is connected, the lower part end surface shape one of the third tooth socket and the first punching
It causes, the depth of the third tooth socket is less than the depth of the first punching lower part；
First punch-pin can be connect with the second punch-pin with upper die holder, first cavity plate and the second cavity plate
It is connect with lower die holder.
It is further improved as the utility model, further includes the first cushion block, the second cushion block and third cushion block, described first
Cushion block, the second cushion block and third cushion block are superimposed together on lower die holder.
Compared with prior art, the utility model has the advantage of simple in structure, reasonable design, development cost is low.This reality
It is to be molded multi-step gear extrusion by secondary extrusion with novel in extrusion process.In simple terms, first a station is squeezed
The first punch-pin and the first cavity plate in mould body are respectively installed to upper die holder, on lower die holder, and blank is put into the first punching, lead to
It crosses the first punch-pin and the molding of the first cavity plate squeezes blank in semi-finished product（As shown in Figure 2）, then that the first punch-pin and second is recessed
Mould removes, and replaces upper second punch-pin and the second cavity plate, and semi-finished product are put into the second punching of the second cavity plate, convex by second
Semi-finished product are squeezed out finished product by mould and the molding of the second cavity plate（As shown in Figure 1）.
