A plurality of (for example two) suction pumps 16 (being aspirator) that upper die unit 2 comprises, it links to each other with last substrate 12.Each suction pump 16 comprises: suction tube 16a, and it runs through the annular wall 11 of substrate 12 downwards; With pump orifice 16b, it is in the end face upper shed of annular wall 11.

On the contrary, lower die unit 3 comprises a plurality of (for example two) elongated block supporting member 26 is used for the periphery of support plate S '.Preferably, each supporting member 26 all is being close to the following blade 27 of cutting out that is connected on the counterdie 23 and is positioning.Therefore, the supporting member 26 of above-mentioned location can vertically be connected down movably on the substrate 22 by bolster 26a, and wherein this bolster 26a has flexible member 26b (for example spring, rubber or other likes) and adjusts nut 26c.That is to say that supporting member 26 links to each other with bolster 26a, this bolster 26a is inserted in the through hole (not shown) that is formed in down in the substrate 22.Flexible member 26b interleave between supporting member 26 and following substrate 22, thereby normally up push supporting member 26.In addition, preferably regulating flexible member 26b by adjusting nut 26c, is the gap (for example accompanying drawing 2) of L2 so that form distance usually between supporting member 26 and following substrate 22.Preferably, flexible member 26b can regulate like this, so that the compacted under face 23a coplane of the upper surface of supporting member 26 and counterdie 23.

Preferably, supporting member 26 can so be arranged, makes the pump orifice 16b of its suction pump 16 of vertically aliging respectively.Therefore, when upper and

lower mould

13 and 23 is closed, can the periphery of sheet material S ' from following side bearing, and apply suction force from upside by suction pump 16 by supporting member 26.Therefore, when upper and

lower mould

13 and 23 was closed, the periphery of sheet material S ' can approximately horizontally locate and support reliably.The result makes, sheet material S ' extrusion modling and can be not wrinkling smoothly, thus produce the moulding material S (not having wrinkle moulded parts Sa) that does not have wrinkle.

Usually, preferably each upper and

lower mould

13 and 23 all has the cooling body (not shown), for example is used for the pipeline of supply cooling fluid (for example water or air).

The following describes the typical method that uses this make-up machine 1 to make moulded parts Sa.

At first, as shown in Figure 2, sheet material S ' is fed in the space between upper and

lower mould

13 and 23 by the conveyer (not shown).Be appreciated that the external dimensions of the external dimensions of sheet material S ' greater than the compacted under face 23a of counterdie 23.Then, the sheet material S ' that is sent to is placed on the counterdie 23, makes its periphery outwards outstanding from the compacted under face 23a of counterdie 23.Like this, sheet material S ' just is arranged on the counterdie 23, so that its peripheral supported part 26 supports.

Afterwards, activate hydraulic cylinder 24, make that substrate 22 moves up towards last substrate 12 down.The result as shown in Figure 3, upper and lower mould 13 and 23 (it links to each other with 22 with substrate 12 up and down respectively) is closed, thus extrusion modling sheet material S ', to form moulding material S.At this moment, the periphery of moulding material S is clamped between the supporting member 26 of the annular wall 11 that goes up substrate 12 and lower die unit 3 reliably.Meanwhile, activate the suction pump 16 of upper die unit 2, so that spur the periphery of moulding material S towards the end face of the annular wall 11 of last substrate 12 by the suction force of suction pump 16.Thereby, supporting the periphery of sheet material S ' reliably.Therefore, sheet material S ' can be molded as moulding material S wrinkle resistantly.In addition, when upper and

lower mould

13 and 23 is closed, preferably activate the hydraulic cylinder 14 of upper die unit 2 so that can keep being formed between substrate 12 and the patrix 13, distance is the gap of L1.

Subsequently, no longer activate the hydraulic cylinder 14 of upper die unit 2, but activate hydraulic cylinder 24 constantly.The result makes, as shown in Figure 4, following substrate 22 further moves up towards last substrate 12 by hydraulic cylinder 24, so that the upper and

lower mould

13 and 23 of closing is shifted onto among the groove 12a of substrate 12 with moulding material S, eliminate up to the gap that forms between last substrate 12 and the patrix 13 (i.e. extreme higher position in the groove 12a of the last substrate 12 of patrix 13 arrival).As shown in Figure 4, at this moment, lower die unit 3 following cut out on blade 27 and the upper die unit 2 and cut out blade 17 engagements, so that along circumferentially moulding material S being cut out, and then produces moulded parts Sa and waste material bar Sb.Simultaneously, the following cutting blade 28 of

lower die unit

3 and 18 engagements of the last cutting blade of upper die unit 2, thereby cutting waste material bar Sb.Be appreciated that instantly substrate 22 when last substrate 12 moves up, because the annular wall 11 of last substrate 12 has stoped supporting member 26 to move up, so promote the supporting members 26 of lower die unit 3 downwards with respect to upper and lower mould 12 and 23.Therefore, the distance L 2 in formed gap is reduced to distance L 3 (equal L2 and deduct L1) between each supporting member 26 and following substrate 22.Therefore, when moulding material S was tailored, the periphery of moulding material S can be clamped between the supporting member 26 of the annular wall 11 that goes up substrate 12 and lower die unit 3 reliably.Therefore, can cut out moulding material S wrinkle resistantly.The result makes that produced moulded parts Sa has the outward appearance of not having wrinkle.

Then, no longer activate hydraulic cylinder 24, thereby substrate 22 is descended.The result as shown in Figure 5, upper and

lower mould

13 and 23 is opened once more.As shown in Figure 5, at this moment, owing to still do not activate the hydraulic cylinder 14 of upper die unit 2, patrix 13 remains on the interior extreme higher position of groove 12a of substrate 12.Therefore, moulded parts Sa just by moulded parts Sa and on the frictional force of cutting out between the blade 17 remain on the patrix 13.On the contrary, the waste material bar Sb suction force that is sucked pump 16 remains on the end face of annular wall 11 of substrate 12.

Afterwards, activating the hydraulic cylinder 14 of upper die unit 2 once more, to move down patrix 13, is the gap of L1 thereby form distance once more between last substrate 12 and patrix 13.The result makes, as shown in Figure 6, is maintained at the moulded parts Sa face release from it on the patrix 13.Then, no longer activate the suction pump 16 of upper die unit 2, the waste material bar Sb that is cut so just discharges from the end face of the annular wall 11 of last substrate 12.Like this, can use this make-up machine 1 to make moulded parts Sa.

When the shaping of finishing moulded parts Sa, can repeat manufacture process in the same manner as described above.

Can carry out various improvement and distortion to this exemplary embodiments exceeding under the situation of scope of the present invention.For example, in this embodiment, the following substrate 22 in the exemplary embodiments moves up by hydraulic cylinder 24.Yet if desired, last substrate 12 can move down by hydraulic cylinder 24.
