As shown in Figure 1 to Figure 2, the mold core 100 for the bellow mold that one embodiment of the invention provides, including mold core body
110 and support construction 130.Specifically, mold core body 110 has the inner cavity 111 of an at least side opening.Mold core body 110
Outer surface has the ripple 113 being arranged around mold core body 110.The direction vertical with ripple 113 is first direction a-a.Support
Structure 130 can be inserted into the inner cavity 111 of mold core body 110, to provide the support perpendicular to first direction a-a for mold core body 110.
The volume of support construction 130 is less than the volume of inner cavity 111.
The mold core 100 of bellow mold can will be inserted into the inner cavity of mold core body 110 in mold assembling or knockout course
111 support construction 130 is taken out, to reduce the weight of mold core 100, that is, reduces lifting weight, is easy to lift operation.
In other words, traditional mold, mold core is entity structure, therefore mold core is heavier.And in the present embodiment, in lifting, only
Lift mold core body 110.Compared to the mold core of traditional entity structure, mold core body 110 it is smaller, to reduce mould
The weight of core 100 is easy to lift operation.
More specifically, the weight of mold core 100 reduces, and in mold assembling or knockout course, is using lesser lifting power
Assembled mold or mold core can be sling, the requirement to the lifting power of the hanging apparatus to sling mold core is smaller.In addition, subtracting
The lifting power of small hanging apparatus, reduces the power of hanging apparatus accordingly, reduces cost.
In addition, the material heating to bellows is formed is needed due in the manufacturing process of bellows, it is corrugated to form
Pipe.The material for forming bellows can be expanded during heating with extrusion die core 100, and mold core 100 will receive external device (ED)
Biggish mechanical force is to guarantee the condition of the indispensable sulfide stress of rubber, so that mold core will receive biggish pressure.If
Only by the external mold of mold core body 110 and mold assembling production bellows, then mold core body 110 may be because of by biggish
Pressure and deform, cause the shape of bellows after molding not to be able to satisfy production requirement.And in the present embodiment, mold core 100 also wraps
The support construction 130 that can be inserted in the inner cavity 111 of mold core body 110 is included, to prevent mould by the support of support construction 130
The deformation of core main body 110, and then produce qualified bellows.
In addition, the volume of support construction 130 is less than the volume of the inner cavity 111 of mold core body 110 in the present embodiment, thus
So that the overall volume of mold core 100 is less than the volume of traditional identical mold core of outer surface size, i.e., so that the weight of mold core 100
Less than the weight of traditional mold core.Therefore in mold assembling or knockout course, even if support construction 130 is not taken out, mold core 100
Weight also more traditional mold core it is light-weight.
When the size of the molding bellows of needs is larger, the structure of mold core 100 is increased will not be too big, so that
Slinging for mold core 100 is more easier.
In the present embodiment, mold core body 110 is run through along first direction a-a in inner cavity 111.On the one hand, inner cavity 111 can be made
It is bigger, to preferably reduce the weight of mold core body 110.On the other hand, mold core master is run through along first direction a-a in inner cavity 111
There are two openings for body 110, i.e. inner cavity 111 tool, so that support construction can be inserted from any one opening of inner cavity 111
Enter the inner cavity 111 of mold core body 110, convenient for the operation of operator.
Specifically, in the present embodiment, mold core body 110 is in Fang Huanzhuan.Support construction 130 includes four support columns 131, is used
With the biggish side wall of opposite two length of carrying mold cores main body 110.And other two side wall length of mold core body 110
It is smaller, it is not susceptible to deformation, so there is no need to support.
It is understood that may be influenced in other feasible embodiment according to the size of mold core body and wall thickness etc.
The factor of mold core body degree of deformability, and the size of single support column, the specific number that support column is set.
It is understood that in other feasible embodiment, if the length of other two side wall of mold core body also compared with
It is long, then need four side walls of setting support construction while carrying mold cores main body.
It further,, can be according to mold core if the structure of mold core body is not Fang Huanzhuan in other feasible embodiment
The specific structure of main body judges its possible the case where deformation occurs, and then judges the position for needing to support accordingly.
In the present embodiment, mold core body 110 includes the core block that several can successively be detachably connected from beginning to end；Adjacent mould
After core insert dismantling connection, several core blocks can be sequentially or simultaneously mobile to the inner cavity of mold core body 110 111.Thus
When demoulding, it can prevent the ripple 113 in the outside of mold core body 110 from squeezing bellows, that is, preventing bellows because being extruded, deformation occurs,
It is unsatisfactory for production requirement so as to avoid because bellows is there is a situation where larger deformation, ensure that the qualification rate of bellows.
In the present embodiment, mold core body 110 is in square central column.Mold core body 110 includes two the first moulds being oppositely arranged
Core insert 112 and two the second core blocks 114 being oppositely arranged.First core block, 112 two sides respectively with two the second moulds
Core insert 114 connects, and 114 two sides of the second core block are connect with the first core block 112 respectively.That is two the first core blocks
112 and two the second core blocks 114 interval join end to end.
More specifically, join Fig. 2, in the present embodiment, the two sides of the first core block 112 are all had and the first core block
The first surface 1121 of the outer surface linking of 112 separate inner cavity 111, the second core block 114 have and can inlay with the first mold core
The second surface 1141 that the first surface 1121 of block 112 is bonded.Perpendicular to the first core block 112 and it is directed toward mold core body 110
The direction of inner cavity 111 be second direction b, the angle of first surface 1121 and second direction b are zero, i.e., first surface 1121 with
Second direction b is parallel.So that the first core block 112 can be complete with molded bellows to being moved to b in a second direction
Total detachment, and then realize the radially disengaging with molding bellows of the first core block 112, avoid the first core block 112
Extruding to molded bellows.
In the present embodiment, the first core block 112 for being moved to the inner cavity 111 of mold core body 110 can opening from inner cavity 111
Mouth end is taken out, so that two the second core blocks 114 can be moved to mold core along the direction perpendicular to the second core block 114
The inner cavity 111 of main body 110 avoids the second mould to realize the radially disengaging with molding bellows of the second core block 114
Extruding of the core insert 114 to molded bellows.
It should be noted that according to the size of the inner cavity 111 of mold core body 110, it can be same by two the first core blocks 112
When or it is successively mobile to second direction b, then two the first core blocks 112 are taken out again；Or first by first mold core
B is mobile in a second direction for insert 112, then takes out, then move and take out another the first core block 112.Likewise, second
The taking-up process of core block 114 is same as above, and details are not described herein again.
It is understood that two the first core blocks 112 are oppositely arranged, and it is located at the two sides of inner cavity 111, therefore two the
The corresponding second direction b of one core block 112 is contrary, joins shown in Fig. 2.
It is understood that first surface 1121 is not limited to parallel with second direction b in other feasible embodiment.
It can also be tilted at an angle with respect to second direction b, meet the angle of first surface 1121 and second direction b i.e. less than 90 degree
It can.Further, in other feasible embodiment, first surface 1121 is also not necessarily limited to plane, can also be curved surface or folding face
Deng rule irregular shape living, meet the section at any place of first surface 1121 and the angle of second direction b less than 90 degree
?.
Further, in this embodiment the two sides of the first core block 112 are equipped with the first protrusion 1123, the first protrusion
1123 have the first confined planes 1124 of the inner cavity 111 far from mold core body 110；The inside of second core block 114 have with
Matched second confined planes 1144 of first confined planes 1124.So as to limit the position of the first core block 112 b in a second direction
It sets, so that b is located at first core block 112 in a second direction when the first confined planes 1124 are abutted with the second confined planes 1144
Predeterminated position, to fast implement determining for the first core block 112 and the second core block 114 when mold core body 110 assembles
Position.
In the present embodiment, the first confined planes 1124 are plane, and vertical with second direction b.It is understood that in addition
In feasible embodiment, the first confined planes 1124 are not limited to vertical with second direction b, are also not necessarily limited to plane, can be to the first mold core
The position of insert 112 and the second core block 114 b in a second direction are positioned.
Similarly, in other feasible embodiment, can also in such a way that relatively matched two confined planes are set,
To be positioned to the first core block 112 and the second core block 114 along the relative position of first direction.
Optionally, the second core block 114 has first inner surface 1145 parallel with second direction b, the first mold core edge
There is interval between the two sides of block 112 and the first inner surface 1145 of the second core block 114.So that the first core block
112 when b in a second direction is mobile, and the first core block 112 will not be contacted with the second core block 114, and then avoids to the
