Specific embodiment
For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with implementation
Mode simultaneously cooperates attached drawing to be explained in detail.
Referring to Fig.1 shown in -5, the utility model provides a kind of hub mold comprising upper mold 1, lower die 2,3 and of left side mould
The right mould 4, upper mold 1 and lower die 2 are class cylindrical shape, and left side mould 3 and the right mould 4 are class semi-cylindrical form.The bottom of the upper mold 1
Portion has die cavity on several spokes circumferentially arranged at equal intervals, and the top of the lower die 2 has and die cavity 24 under several spokes
Die cavity under one-to-one spoke, upper mold 1 and lower die 2 dock form spoke die cavity 52 along the vertical direction, left side mould 3 and the right mould
4 close up to form wheel rim die cavity 51 from the right and left to upper mold 1 and lower die 2.
Wherein, hub mold further includes having several pieces of inserts 22, and die cavity 24 is set in the outer of lower die 2 under two neighboring spoke
There is block 21, the inner edge of each block 21 is abutted with the bottom of upper mold 1, and the side of the interior half portion of two neighboring block 21 surrounds appearance
Slot 23 is set, which is located under spoke above die cavity 24, and several pieces of one-to-one correspondence of insert 22 are removably embedded and are accommodating
In slot 23.Specifically, the upper surface of block 21 is arc surface, and insert 22 is fully filled with accommodation groove 23,22 upper surface of insert and gear
Block 21 cooperatively forms complete circle arc ring face and the inner edge of the insert 22 and the inner edge of block 21 are spliced to form complete round edge.
The complete round edge that insert 22 and block 21 are spliced to form abuts to form flange collar die cavity, specifically, upper mold with upper mold 1
1 bottom is the structure of class bottom of bowl, as shown in figure 3, the first flange collar die cavity cell wall 11, the edge are formed on the bottom of the upper mold 1
The upper surface of block 22 and block 21, which maintains an equal level, to be arranged to form the second flange collar die cavity cell wall 25, in this way, working as left side mould 3 and the right mould 4
Flange collar die cavity 54 can be formed by closing up respectively from the right and left to upper mold 1 and lower die 2.
The main innovation point of the utility model is to occupy die cavity sky by being additionally arranged block 21 and insert 22 in lower die 2
Between, block 21 is specifically added between die cavity 24 under two neighboring spoke in lower die 2, and two neighboring block 21 is under spoke
The position of die cavity 24 forms accommodation groove 23, and insert 22 is movably arranged in accommodation groove 23 while block 21 is fixedly connected with lower die 2.
Insert 22 is placed in accommodation groove 23 before injecting casting liquid, since insert 22 and the cooperation of block 21 reduce 54 sky of flange collar die cavity
Between, so that the thickness of flange collar 611 greatly reduces, the processing cost of wheel hub entirety, Er Qiehou are not only reduced because having saved material
Degree is smaller to be not easily formed cinder hole in injection molding process, is conducive to promote processing quality.Also, after wheel hub blank molding, gear
Block 21 is detached from the lower die 2, and insert 22 is from side by abate, therefore insert 22 will not be stuck between spoke 62 and wheel rim 61,
To realize demoulding completely.
As the preferred embodiment of the utility model, the insert 22 is made of iron material, and iron material has low in cost
With wear-resisting advantage, easy to process and long service life.
It is furthermore preferred that the insert 22 is hollow structure, 22 volume of insert is larger and iron material easily absorbs heat, and absorbs insert 22
The heat that periphery casting liquid transmits, cooling sequencing can be interfered during subsequent cooling and shaping, causes 61 He of wheel rim
The link position solidification of spoke 62 is too fast, influences the cooling equilibrium of entirety, is heat-shrinked unevenly, be easy to cause into it will cause whole
Type wheel hub blank is easily-deformable.Therefore, insert 22 is emptied, and forms hollow structure, iron material is significantly less, can reduce the suction of insert 22
Heat effectively avoids influencing processing quality to guarantee that the link position of wheel rim 61 and spoke 62 will not lose excessive heat.
The above description is only the embodiments of the present invention, is not intended to limit the scope of patent protection of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
