Upper recess 137 can be formed at the bottom of the groove portion 136 formed in the upper surface of movable pressure plate 13.Upper recess 137 can
For the channel-shaped that both ends open.The long side direction of upper recess 137 can be set to left and right directions.
Lower concave part 138 can be formed at the bottom of the groove portion 136 of the lower surface formation in movable pressure plate 13.Lower concave part 138 can
For the channel-shaped that both ends open.The long side direction of lower concave part 138 can be set to left and right directions.
By forming upper recess 137 and lower concave part 138, the power of the pushing against mold installation portion 131 of pressing plate main body 132 concentrates on mould
The above-below direction central portion of tool installation portion 131, and the uniformity of the mold clamping force of die device 30 can be improved.
Horizontal recess 139 is formed at the lateral surface of a pair of linking parts 133.The power of the pushing against mold installation portion 131 of pressing plate main body 132
The left and right directions central portion of mold mounting section 131 is concentrated on, and the uniformity of the mold clamping force of die device 30 can be improved.
As shown in fig. 6, when the section observation vertical with the action direction of mold clamping force (fore-and-aft direction), horizontal recess 139
Both ends do not open, and can have convex portion in the right and left of horizontal recess 139.Rigid decline can be suppressed, and improve mould
The uniformity of the mold clamping force of device 30.
In addition, when the section observation vertical with fore-and-aft direction, only can have convex portion in the side of horizontal recess 139.Also,
When observing from the section vertical with fore-and-aft direction, only there can be convex portion at least side of upper recess 137 and lower concave part 138.
Then, refer again to Fig. 1~Fig. 2 to illustrate fixation clip 12.Fixation clip 12 is same with movable pressure plate 13
Ground has mold mounting section 121, pressing plate main body 122 and linking part 123.In the present embodiment, mold mounting section 121, pressing plate
Main body 122 and linking part 123 form as one, but it is also possible to which split is formed and linked.
The face opposed with movable pressure plate 13 of mold mounting section 121 has the die mounting surface for being provided with cover half 32.In order to
Avoid mold mounting section 121 from contacting with connecting rod 16, there is through hole in the position for being equipped with connecting rod 16.Alternatively, it is also possible to
Form breach to replace through hole, it is also possible to form both through hole and breach.
Pressing plate main body 122 is disposed in the front of mold mounting section 121, and opposed with mold mounting section 121.Pressing plate main body
122 are securable to framework 11.In addition, in the case that rear fender 15 is fixed on framework 11, pressing plate main body 122 can be relative to framework 11
Free to advance or retreat, pressing plate main body 122 can also be placed on framework 11, it is also possible to be fixed on along guiding piece 17 and moved cunning freely
Block.
Hole is formed through in pressing plate main body 122, connecting rod 16 can be inserted through in the through hole.The front end of connecting rod 16
Pressing plate main body 122 is fixed in portion.Pressing plate main body 122 pushes back mold mounting section 121 via linking part 123 in matched moulds.
Linking part 123 is disposed between mold mounting section 121 and pressing plate main body 122, and in mold mounting section 121 during matched moulds
Power is transmitted between pressing plate main body 122.Can be in the same manner as linking part 133 in the lateral direction across being interval with multiple (such as 2
It is individual) linking part 123.In addition, linking part 123 is formed as frame-shaped, the shape of linking part 123 can also be of all kinds.
Linking part 123 can form the groove portion 126 of both ends opening between mold mounting section 121 and pressing plate main body 122.Groove
The long side direction in portion 126 can be set to left and right directions.As shown in Figures 1 and 2, can divide in the upper surface of fixation clip 12 and lower surface
Xing Cheng not groove portion 126.By forming groove portion 126, pressing plate main body 122 concentrates on the power that mold mounting section 121 is pushed back during matched moulds
The above-below direction central portion of mold mounting section 121, and the uniformity of the mold clamping force of die device 30 can be improved.
In addition, the position of groove portion 126 is not particularly limited.For example, groove portion 126 can be formed at the left and right of fixation clip 12
Two sides.Now, the power that mold mounting section 121 is pushed back is concentrated on pressing plate main body 122 left and right of mold mounting section 121 during matched moulds
Direction central portion, and the uniformity of the mold clamping force of die device 30 can be improved.Groove portion 126 can be formed at the upper of fixation clip 12
Lower surface and left and right sides.Also, groove portion 126 can also only be formed at any surface in the upper and lower surface of fixation clip 12,
Any surface that can also be only formed in the left and right sides of fixation clip 12.
The outer surface of linking part 123 has the recess than peripheral recesses.It is formed with the recess of more than 1.Such as Fig. 1 and figure
Shown in 2, the upper surface of linking part 123 has upper recess 127, and lower surface has lower concave part 128, and lateral surface has horizontal recess 129.
Upper recess 127 can be formed at the bottom of the groove portion 126 formed in the upper surface of fixation clip 12.Upper recess 127 can
For the channel-shaped that both ends open.The long side direction of upper recess 127 can be set to left and right directions.
Lower concave part 128 can be formed at the bottom of the groove portion 126 of the lower surface formation in fixation clip 12.Lower concave part 128 can
For the channel-shaped that both ends open.The long side direction of lower concave part 128 can be set to left and right directions.
By forming upper recess 127 and lower concave part 128, pressing plate main body 122 concentrates on the power that mold mounting section 121 is pushed back
The above-below direction central portion of mold mounting section 121, and the uniformity of the mold clamping force of die device 30 can be improved.
Horizontal recess 129 is formed at the lateral surface of a pair of linking parts 123.Pressing plate main body 122 pushes back mold mounting section 121
Power concentrates on the left and right directions central portion of mold mounting section 121, and can improve the uniformity of the mold clamping force of die device 30.
When observing from the section vertical with the action direction of mold clamping force (fore-and-aft direction), the both ends of horizontal recess 129 do not have
It is open, there can be convex portion in the right and left of horizontal recess 129.Rigid decline can be suppressed, and improve the conjunction of die device 30
The uniformity of mould power.
In addition, when the section observation vertical with fore-and-aft direction, only can have convex portion in the side of horizontal recess 129.Also,
When observing from the section vertical with fore-and-aft direction, only there can be convex portion at least side of upper recess 127 and lower concave part 128.
