Fig. 3 is the figure of the example representing the fixation clip observed from movable pressure plate side.In figure 3, it is omitted in fixation clip The diagram making the hole that connecting rod 16 runs through on 12.It addition, in figure 3, there are also shown and see not owing to there is plate body 51L, 51R The part arrived.Fig. 4 is the profile of the IV-IV line along Fig. 3.

As it is shown on figure 3, fixation clip 12 is fixed on framework 11 across fixation clip supporting parts 40L, 40R.

Fixation clip supporting parts 40L, 40R grip pressing plate 12 and are arranged at the left and right sides.Fixation clip support Part 40L, 40R are erected on framework 11, from side (left and right directions) the supporting and fixing pressing plate 12 vertical with mould opening and closing direction.Right and left It is mutually orthogonal direction to, fore-and-aft direction (mould opening and closing direction) and above-below direction.

Fixation clip supporting parts 40L, 40R have the mounting surface of mounting fixation clip 12, and from framework 11 separated by a distance And supporting and fixing pressing plate 12.Fixation clip 12 and framework 11 not in contact with, be formed with gap between fixation clip 12 and framework 11. Therefore, the fixation clip 12 that heat is difficult to contact from the die device 30 with high temperature when injection moulding is to than fixation clip 12 more The framework 11 of low temperature moves, and is not likely to produce the temperature inequality becoming the reason that fixation clip 12 tilts.Therefore, it is possible to suppression is solid The inclination of fixed pressuring plate 12, and the depth of parallelism of cover half 32 and dynamic model 33 can be kept, it is possible to by the mold clamping force of cover half 32 with dynamic model 33 Distribution relative to die device 30 centrage keep symmetry.

As it is shown on figure 3, fixation clip supporting parts 40L, 40R possess: basilar part 41L, 41R, it is installed on framework 11；Post portion 42L, 42R, highlight upward from basilar part 41L, 41R；And fitting portion 43L, 43R, flatly dash forward from the front end of post portion 42L, 42R Go out.

As it is shown on figure 3, basilar part 41L, 41R and post portion 42L, 42R, do not contact with fixation clip 12, and with fixing pressure Gap is formed between plate 12.Heat is difficult to be moved to framework 11 by fixation clip supporting parts 40L, 40R from fixation clip 12. Therefore, the Temperature Distribution of fixation clip 12 becomes prone to symmetrical relative to the centrage of die device 30.

As it is shown on figure 3, basilar part 41L, 41R the most longer than post portion 42L, 42R in the lateral direction. Owing to basilar part 41L, 41R are the most elongated with the contact surface of framework 11, therefore, it is possible to suppression basilar part 41L, 41R to The movement of the left and right directions of fitting portion 43L, 43R.Consequently, it is possible to fixation clip 12 becomes to be difficult to thermal expansion in the lateral direction, Therefore the centrage of fixation clip 12 is difficult to deviate in the lateral direction.Fixation clip 12 is difficult to thermal expansion in the lateral direction, with This becomes easy thermal expansion the most in the vertical direction, but owing to separating with framework 11, therefore, it is possible to the most equal Etc. ground extend.Therefore, the position of the above-below direction of the centrage of fixation clip 12 mainly with to fixation clip supporting parts 40L, The ductility of the above-below direction of 40R determines.Further, fixation clip supporting parts 40L, 40R and movable pressure plate supporting parts 60L, 60R are heated with same degree, and vertically extend with same degree.Therefore, the centrage of fixation clip 12 and The same direction of center alignment (such as top) of movable pressure plate 13 is moved simultaneously, is therefore difficult to vertically deviate.Thus, Gu The centrage of fixed pressuring plate 12 and the centrage of movable pressure plate 13 are difficult to deviation.

As it is shown on figure 3, basilar part 41L, 41R are for the most longer than post portion 42L, 42R in the lateral direction, Towards the gap formed between fixation clip 12 and framework 11, prominent from post portion 42L, 42R inner side in the lateral direction.Base 41L, 41R will not be the most protruding outside from post portion 42L, 42R in bottom, and the left and right directions length of framework 11 is shorter, it is possible to Realize the miniaturization of injection (mo(u)lding) machine 10.Between the end of basilar part 41L, 41R can enter between fixation clip 12 and framework 11 Gap.

Fitting portion 43L, 43R are chimeric with fixation clip 12.Fitting portion 43L, 43R can side upper of supporting and fixing pressing plate 12 Lower direction central part.

Supporting parts 40L, 40R are chimeric with fixation clip 12 for fixation clip.That is, parts 40L, 40R are supported at fixation clip And the protuberance of a square one-tenth of fixation clip 12 is chimeric with the recess formed the opposing party.

If making fixation clip 12 chimeric with fixation clip supporting parts 40L, 40R, then can limit fixation clip 12 with solid The relative property of fixed pressuring plate supporting parts 40L, 40R moves.Such as, as it is shown on figure 3, fixation clip supporting parts 40L, 40R will consolidate Fixed pressuring plate 12 clamps from the left and right sides, determines the fixation clip 12 position relative to the left and right directions of framework 11.It addition, fixing pressure Plate supporting parts 40L, 40R and framework 11 support fixation clip 12 across predetermined interval, and determine fixation clip 12 relative to The position of the above-below direction of framework 11.

The side supporting parts 40L, 40R at fixation clip 12 and fixation clip is provided with the opposing party the most embedding The guiding groove closed.Such as it is shown on figure 3, be provided with in the side of fixation clip 12 that fixation clip supports parts 40L, 40R(is detailed Thin be fitting portion 43L, 43R) guiding groove 18L, 18R of being fitted together to sliding freely.
