Description
Technical field
The present invention relates to the lower die for using separate structure and apply its hub mold.
Background technology
A kind of injection mold, including 1 He of impression bolster are disclosed in Chinese utility model patent CN201784145U
Chamber frame 3, the impression bolster 1 are located at the top of the chamber frame 3.It is provided with injection hole in the impression bolster 1
2, cavity 4 is provided in the chamber frame 3.Sprue 5, the mainstream are provided on the chamber frame 3 and the cavity 4
Road 5 is connected to the injection hole 2.It is additionally provided with dismountable gating insert 6 on the cavity 4, is set on the gating insert 6
It is equipped with into cast gate 7, a connection sprue 5 into cast gate 7, other end is connected to die cavity.In this way, when needing to change injection molding work
Skill is described when being damaged into cast gate 7, it is only necessary to replace the gating insert 6 without replacing monoblock cavity 4.Such one
The manufacturing cost of mold is greatly reduced, but at the same time also causes the formation of another problem.Using mold manufacturing
During mechanograph, the temperature of the cavity 4 and gating insert 6 is often as high as 350 DEG C~500 DEG C and generates apparent hot swollen
Bulging deformation.The especially described gating insert 6, the high-temperature molten material into cast gate 7 flowed through thereon cause the cast gate to be inlayed
The thermal expansion deformation amount bigger of block 6.The gating insert 6 and cavity 4 of thermal expansion deformation deteriorate the injection mold simultaneously
Stress situation, to influence the service life of injection mold and the dimensional accuracy of mechanograph.
Invention content
In view of the deficiencies of the prior art, the present invention proposes a kind of lower die using separate structure, including lower die main body is under
Mold core, is provided with axially extending installation through-hole in the lower die main body, and the lower mold core is removably plugged on the peace
It fills in through-hole, feed inlet is provided in the lower mold core；It is characterized in that, the installation that is plugged in the lower mold core is led to
Multiple circumferentially-spaced arrangements and axially extending groove are provided on lateral wall in hole；Or the endoporus in the installation through-hole
Multiple circumferentially-spaced arrangements and axially extending groove are provided on wall.
Further technical solution is also possible that the groove deep 0.14~0.17mm, wide 15~25mm.
Further technical solution is also possible that the upper position in the lower mold core is provided with connecting flange side, fastens
Part is fixed on the lower mold core in the lower die main body across the connecting flange side.
The present invention also proposes the hub mold using the lower die, which is characterized in that including the upper mold split up and down and institute
Lower die is stated, side form is additionally provided between the upper die and lower die, the upper die and lower die and side form are surrounded for casting hub
Cavity, the feed inlet are connected to the cavity.
According to above-mentioned technical proposal, compared with prior art, the beneficial technical effect of the present invention lies in：
1. on the basis of the lower die uses separate structure, by logical in the lateral wall of the lower mold core or the installation
The groove is provided on the inner hole wall in hole, the setting of the groove described in this way is so that the lateral wall in the lower mold core and the peace
Gap is formed between the inner hole wall of dress through-hole, the gap can carry for the thermal expansion deformation of the lower die main body and lower mold core
For deformation space, stress state of lower die during military service is optimized, the service life of the lower die is conducive to extend
With the dimensional accuracy for improving die products.
2. due to being provided with connecting flange side in the upper position of the lower mold core, in this way, passing through the connecting flange side
Easily the lower mold core can be fixed in the lower die main body, while can also be easily the lower mold core from described
It is disassembled in lower die main body.
Due to the present invention have the advantages that These characteristics and, can be applied to thus using separate structure lower die and using its
Hub mold on.
Description of the drawings
Fig. 1 is the schematic cross-sectional view using the lower die using separate structure of technical solution of the present invention；
Fig. 2 is the portions the A enlarged structure schematic diagram in Fig. 1；
Fig. 3 is the dimensional structure diagram of the lower mold core.
Specific implementation mode
Below in conjunction with the accompanying drawings to application technical solution of the present invention using the lower die of separate structure and using its wheel hub mould
The structure of tool is further described.
A kind of hub mold（Structure is relatively easy, omits relevant view）, including the upper die and lower die that split up and down, in institute
It states and is additionally provided with side form between upper die and lower die, the upper die and lower die and side form surround the cavity for casting hub.Wherein institute
It states lower die 2 and uses separate structure.As shown in Figure 1, Figure 2 and Figure 3, the lower die 2 includes lower die main body 21 and lower mold core 22, in institute
It states and is provided with axially extending installation through-hole in lower die main body 21（It is blocked by lower mold core 22 in Fig. 1, therefore is not marked）, institute
Lower mold core 22 is stated removably to be plugged in the installation through-hole.Be provided with feed inlet 220 in the lower mold core 22, it is described into
