Abstract
The utility model discloses a kind of half-closed automobile gearbox gear forging and molding molds, including upper mold (1), lower mold (2), there are upper model cavity (6) in the upper mold, there are drag chamber (5) in the lower mold, there are flash gutters (7) between the upper mold and lower mold, under the upper mold, and the half-closed extruding bulge loop (3) of upper mold is housed between flash gutters and upper model cavity, on the lower mold, and the half-closed extruding concave ring (4) of lower die is housed between flash gutters and drag chamber, and the half-closed extruding bulge loop of upper mold and the half-closed extruding concave ring of lower die are corresponding mutually embedding, with gap.The utility model increases material and flows to resistance at flash gutters, material is promoted to be full of drag chamber, upper model cavity at first, after material full of the flash gutters of two sides are flowed out and flowed to respectively in material extrusion from two czermak spaces again after upper and lower model cavity, to accordingly reduce forging hitting power, stock utilization and die life are improved, rejection rate is reduced.
Description
Technical field
The present invention relates to a kind of automobile gearbox gear forging molding molds.
Background technique
Automobile gearbox gear is applied in automobile gear shift gearbox, bears very big load, due in gear product distribution
Between there are three plateau at low, circumferential edges, so stock utilization is low when forging, the high point of product plateau is not easy to fill, waste product
Rate is higher.Conventional open die forges that the product qualification rate is low, and stock utilization is low；Closed molds forging is then since gear produces
Product high point is distributed at wheel rim and asymmetry, so needing hitting power big, shortens die life.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and pass through and change mould structure, in enclosed and open die
Innovation provides a kind of half-closed automobile gearbox gear forging and molding mold between lamps structure, reaches and both reduces forging force, improves
Die life saves the purpose of material again.
The purpose of the present invention is realized by following technical solution: half-closed automobile gearbox gear forging and molding mold,
Including upper mold, lower mold, with having drag chamber in upper model cavity, the lower mold in the upper mold, in the upper mold
There are flash gutters between lower mold, upper mold semi-closure is housed under the upper mold and between flash gutters and upper model cavity
Formula squeezes bulge loop, and the half-closed extruding concave ring of lower die is housed on the lower mold and between flash gutters and drag chamber, and
The half-closed extruding bulge loop of upper mold it is corresponding with the half-closed extruding concave ring of the lower die it is mutually embedding, there is gap.
It is upper and lower gap 2.0-3.0mm, side between the half-closed extruding bulge loop of the upper mold and the half-closed extruding concave ring of lower die
The position arrangement of face gap 0.8-1.5mm, side draft angle 3.0-7.0 degree.
After applying the present invention, during forging, due to the half-closed extruding bulge loop of upper mold and the half-closed extruding concave ring of lower die
It is setting up and down, increase material and flow to resistance at flash gutters, material is promoted to be full of drag chamber at first, at upper model cavity,
After material full of the flash gutters of two sides are flowed out and flowed to respectively in material extrusion from two czermak spaces again after upper and lower model cavity, thus phase
Forging hitting power should be reduced, stock utilization and die life is improved, reduces rejection rate.
Detailed description of the invention
The present invention is described in further detail with specific embodiment with reference to the accompanying drawing.
Fig. 1 is the mounting structure schematic diagram of the present invention (when upper and lower mold is opened).
Fig. 2 is the mounting structure schematic diagram of the present invention (when upper and lower mold is closed).
Fig. 3 is that the half-closed extruding bulge loop of upper mold in Fig. 1 connects schematic diagram with upper model cavity.
Fig. 4 is that the half-closed extruding concave ring of lower die in Fig. 1 connects schematic diagram with drag chamber.
Specific embodiment
Referring to figs. 1 to Fig. 4 it is found that the half-closed automobile gearbox gear forging and molding mold of the present invention, including upper mold 1,
Lower mold 2, with having drag chamber 5 in upper model cavity 6, the lower mold 2 in the upper mold 1, in the upper mold 1 and lower die
There is flash gutters 7 (each one of left and right side) between tool 2, under the upper mold 1 and between flash gutters 7 and upper model cavity 6
Place is equipped with half-closed the extrudings bulge loop 3 (as shown in Figure 3) of upper mold, on the lower mold 2 and flash gutters 7 and drag chamber 5 it
Between half-closed the extrudings concave ring 4 (as shown in Figure 4) of lower die is housed, and the half-closed extruding bulge loop of the upper mold 3 and the lower die are partly
The correspondence of Closed Extrusion concave ring 4 is mutually embedding, has gap.The half-closed extruding bulge loop 3 of the upper mold and the half-closed extruding concave ring 4 of lower die it
Between for upper and lower gap 2.0-3.0mm, side clearance 0.8-1.5mm, side draft angle 3.0-7.0 degree position arrangement, therefore also known as
It is half-open half-closed.
Working principle of the present invention are as follows: during forging, also flow direction flies material while being full of upper mold or drag chamber
Side slot, due to more high-leveled and difficult to be full of at the drag chamber 5 of lower mold, material can be flowed to first at the flash gutters in left side, can be made in this way
It is discontented at being filled at drag chamber, so increasing upper and lower gap 2.0-3.0mm, side between upper mold 1 and lower mold 2
The half-closed extruding bulge loop of upper mold and the half-closed extruding concave ring 4 of lower die of gap 0.8-1.5mm, side draft angle 3.0-7.0 degree increase
Add material to flow to the resistance at flash gutters 7, has promoted material to be full of drag chamber 5 at first, at upper model cavity 6, be full of to material
The flash gutters 7 of two sides are flowed out and are flowed to respectively in material extrusion from two czermak spaces again after upper and lower model cavity, to reduce strike
Power improves stock utilization and die life, reduces rejection rate.
