Description
Technical field
The utility model is related to a kind of hub of motorcycle molds equipped with insert.
Background technology
The thinner and many spoke of the most spoke of Motorcycle Aluminum Alloy wheel hub on the market is U-shaped or V-arrangement at present,
There are trade mark or other identifier, the loss of weight that such design mainly carries out under the premise of performance is not influenced on the spoke of part
Design reduces production cost, but corresponding is then inverted U-shaped or inverted V-shaped protuberance on mold, and the both sides swelled and surrounding mould
Between have the relatively thin deeper ditch of item, corresponding is exactly the edge of spoke on wheel hub, and molten aluminium alloy is in ditch in casting process
Runner is slowly and exhaust is not smooth, can cause to owe casting or loose, therefore, in order to ensure the quality of hub cast, need in ditch bottom
A large amount of venting plug exhaust is set with the top of protuberance, owes to cast to avoid casting or loose, a large amount of bumps is had after casting demoulding
Venting plug print, need to polish off, not in place or polishing of easily polishing in polishing is excessive or deformation, influences presentation quality,
Increase polishing cost, and venting plug easily blocks, castability is just influenced after blocking, lower machine is needed to replace venting plug, workload
Efficiency greatly is low, increase great amount of cost, therefore, owes to cast or be vented bad, reduction or cancellation polishing workload to reduce casting, right
It is very necessary that mold, which is improved design,.
Utility model content
The utility model is intended at least solve one of technical problem present in the prior art or the relevant technologies.
For this purpose, a purpose of the utility model is to propose a kind of hub of motorcycle mold equipped with insert, including
Upper die and lower die and Bian Mo are embedded with insert at the fin of every spoke of lower die, and insert is consistent with fin moulding, insert from
The back side of lower die is fixed after being fitted into fin.
Wheel hub mid-game casting mould provided by the utility model, insert are packed into from the lower die back side, the gap of insert and lower die
Exhaust passage can be become, multiple venting plugs are replaced with the gap after assembly, caused by solution venting plug blocking final vacuum is not smooth
Castability problem saves the troublesome problem that venting plug is replaced in machine cleaning under mold, has prevented fin substantially and its bottom is recessed
The exhausting problem of slot has ensured castability, reduces foundary loss.
According to the above-mentioned wheel hub mid-game casting mould of the utility model, there can also be following additional technical feature：
In the above-mentioned technical solutions, it is preferable that insert is obtained for the spoke fin of lower die after wire cutting, under insert insertion
Several bolt hole blending bolts are opened up at the installation gap formed in outer end face after mould to fix.
In above-described embodiment, the part of the upper end of insert for the cavity surface of side mould, insert is from the spoke fin of former lower die
On cut down, insert processing technology is simple, and moulding is consistent with lower die, fits together perfectly after insert insertion lower die, avoids leakage aluminium etc.
Defect prevents insert toward outside or medial movement after the fastening of screw thread blending bolt is opened up at the gap of outer end face.
In the above-mentioned technical solutions, it is preferable that the top of insert is equipped with several venting plugs.
In above-described embodiment, the top of insert sets several venting plugs, is conducive to the spoke indent position of hub cast
Exhaust, opens up venting plug in insert, even if after venting plug blocks, it, only need to be by insert from lower die without machine under whole secondary mold
The back side, which is unloaded down, carries out replacement venting plug, simple and convenient, saves mold machine time and cost up and down.
The additional aspect and advantage of the utility model will become apparent or new by this practicality in following description section
The practice of type is recognized.
Description of the drawings
The above-mentioned and/or additional aspect and advantage of the utility model will in the description from combination accompanying drawings below to embodiment
Become apparent and be readily appreciated that, wherein：
Fig. 1 is a kind of hub of motorcycle mould structure front view equipped with insert provided by the utility model；
Fig. 2 is the bottom view of Fig. 1.
Specific embodiment
In order to be more clearly understood that the above-mentioned purpose of the utility model, feature and advantage, below in conjunction with the accompanying drawings and have
The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen
The feature in embodiment and embodiment please can be combined with each other.
Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality
It is novel to be implemented using other different from mode described here, therefore, the scope of protection of the utility model not by
The limitation of following public specific embodiment.
As depicted in figs. 1 and 2, the embodiment of the utility model provides a kind of hub of motorcycle mold equipped with insert,
Including upper die and lower die and Bian Mo, insert 12 is embedded at the fin 11 of every spoke 1 of lower die, insert 12 is made with fin 11
Type is consistent, and insert 12 is fixed after being fitted into fin 11 from the back side of lower die.
Wheel hub mid-game casting mould provided by the utility model, insert 12 are packed into from the lower die back side, insert 12 and lower die
Gap can become exhaust passage, and multiple venting plugs 13 are replaced with the gap after assembly, solve venting plug 13 and block final vacuum not
Castability problem caused by smooth saves the troublesome problem that venting plug 13 is replaced in machine cleaning under mold, has prevented fin substantially
