So that the power for acting on the 1st joint portion 17a is reduced, can prevent from combining the fastening part between portion 17b with the 2nd in the 1st joint portion 17a
Position acts on extra power.Therefore, when extracting running channel R from mold, the 1st joint portion 17a and the 2nd joint portion 17b can be prevented
Combination be released from, detached.Moreover, by inhibit when being extracted from mold the 1st joint portion 17a with the 2nd combine portion 17b it
Between fastening position act on extra power, the 1st joint portion 17a and the 2nd joint portion 17b at the time of completing to shape can be inhibited
In conjunction with such situation that died down.Therefore, even if it is complete the synthetic resin of present embodiment is applied to plastic pattern
The component of the plastic pattern of element and in the case of supporting the running channel of component of the plastic pattern, by plastic pattern complete set
Commodity bundle is put into case and in the way carried, can also inhibit the 1st joint portion 17a caused by vibrating, impacting and
The combination of 2nd joint portion 17b is released from such state of affairs.
In addition, in the present embodiment, constituting the wall portion 17a1 and bottom 17a2 of the 1st joint portion 17a respectively by thin-walled
Component formed, therefore, from mold extract above-mentioned running channel R when, the power for acting on the 1st joint portion 17a can be further decreased,
And the solidification of aftermentioned 1st joint portion 17a can be made to shift to an earlier date.Such as making the thickness t1 of above-mentioned 1st joint portion 17a it is about
In the case of 1.5mm, the thickness of bottom 17a2 can be set as about 0.5mm.
Moreover, the 1st joint portion 17a relative to the 1st adjacent running channel portion A1, with the 1st combine the identical length of portion 17a
Volume is shaped with smaller volume.Specifically, with reference to (A) of Fig. 5, the axial length of the 1st joint portion 17a is set as d1, it will
1st running channel portion A1's combines the identical axial lengths of portion 17a with the 1st and is set as d2.D1 and d2 is identical length.At this point, setting
Volume for the length d2 of the 1st running channel portion A1 of volumetric ratio of the length d1 of the 1st joint portion 17a is small.In addition, it is previous, it is equivalent to the 1st
The position in joint portion is with for example, about thickness of 2.5mm by solid forming.
That is, as described above, it is thinner than the 1st running channel portion A1 that the 1st joint portion 17a is set as thickness, and due to being set as by thin
The concave shape that the wall portion 17a1 and bottom 17a2 of wall are constituted, therefore become smaller compared with the 1st running channel portion A1 of identical length
Volume.By in this way, relative to the 1st running channel portion A1 for combining 17a adjoinings in portion with the 1st, by its smaller volume, and expand with
The contact area of mold can carry out the solidification of the 1st joint portion 17a in advance in aftermentioned forming as a result,.
< forming processes > illustrates the molding work of the running channel R of first embodiment with reference to (A) of Fig. 6 and (B) of Fig. 6
Sequence.Sectional view shown in (A) of Fig. 6 and (B) of Fig. 6 is cuing open of being in by the line VI -- VI cut-out mold of such as Fig. 3 (A)
Face figure.First, when making 51 mold closing of formpiston 5 and former as shown in Figure 1, injection moulding apparatus (not shown) is connect with mold,
It is flowed through from the side of running channel slot from the recess portion 11 of such as connection injection-moulding nozzle to formingspace 18 and the injection molding of running channel slot 16
1st Resin A (the 1st injection step).Then it is completed without waiting for the injection molding of the 1st Resin A, injection moulding apparatus is molded spray from such as connection
The recess portion 12 of mouth flows through the 2nd resin B (the 2nd injection step) come to mold injection from the other side of running channel slot 16.
In the 1st injection step, as shown in (A) of Fig. 6, the 1st Resin A right side flow in left lateral view from figure is pouring
Face (limitation face) 36 sides of the side in road slot 16, partition member 30a are that the space configured with protrusion 16b is filled with the 1st
Resin A.The limitation surface side limitation of partition member 30a at this time flows through the 1st Resin A come from the side (left side in figure) of running channel slot 16
Flowing (limitation process).That is, the inflow direction of the face 36 of the side of partition member 30a and shaping resin material is at substantially straight
Angle can prevent the flowing of the shaping resin material for 36 side of face for flowing to the side.Also, the 1st Resin A is in partition member
The face 36 of the side of 30a is plugged, and stops flowing.
The 1st Resin A is in the 1st joint portion of the 16 internal shaping concave shape of running channel slot of face (limitation face) 36 sides of side at this time
(concave shape portion) 17a (the 1st forming process), the 1st joint portion 17a have the one of bottom 17a2 and encirclement partition member 30a
Partial wall portion 17a1.Here, with reference to (A) of Fig. 3 and (C) of Fig. 3, the protrusion 16b in running channel slot 16 has:1st side
Face 16b1 is opposite with the face 16d of running channel slot 16;And the 2nd side 16b2, it is left with the face of the side of partition member 30a
Predetermined distance and along partition member 30a a part extend.As shown in (C) of Fig. 3, the 2nd side 16b2 and separation structure
Leave the amount of predetermined distance d in the face of the side of part 30a.In addition, as described above, due to the wall portion 17a1 tools of the 1st joint portion 17a
There is inclined surface, therefore, at least face 16d of the 1st side 16b1 of protrusion 16b and running channel slot 16 is formed as inclined surface.
As described above, the 1st joint portion 17a of concave shape is formed by the wall portion 17a1 and bottom 17a2 of thin-walled, and
Since its volume settings is obtained smaller therefore meeting premature cure.That is, the 1st joint portion 17a using the protrusion 16b of running channel slot 16 and
Therefore the wall portion 17a1 of bottom 17a2 and the surrounding thin-walled of encirclement with thin-walled expand the contact area with mold and carry
Preceding solidification.
For example, in the running channel slot 16 that protrusion 16b is not formed, it is formed with not at the position for being equivalent to the 1st joint portion
Solid running channel with concave shape.If it does, then needing the stipulated time cooling inside solid running channel, with this embodiment party
1st joint portion 17a of concave shape as formula compares, and can spend defined time until solidification.Therefore, with it is previous
It compares, can promptly be cured (curing process) by the 1st joint portion 17a of the concave shape of the 1st Resin A forming.
Then, as shown in (B) of Fig. 6, by the injection-moulding nozzle that links with connection recess portion 55 by the 2nd of such as different colours the
Resin B is molded to running channel slot 16.When the 2nd resin B (on the right side of from figure to the left) is flowed into from the other side of running channel slot 16, the 2nd
Resin B is temporarily blocked by the face 37 of the other side of the small diameter portion 35 of partition member 30a, and step recess portion 40 is then flowed into.By this
The hemispherical recesses 41a of the flowing pressure of 2nd resin B, step recess portion 40 is pressed towards the directions arrow A, 30a grams of partition member
It is pushed with taking the active force of elastic component 31a.State at this time is shown in (B) of Fig. 3.Therefore, partition member 30a passes through
The flowing that the 2nd resin B come is flowed through from the other side of running channel slot 16 is kept out of the way from running channel slot 16 and (keeps out of the way process).Like this, the 2nd tree
Fat B shapes the joint portion (the 2nd formation process) engaged with the concave shape portion formed in the 1st forming process.
That is, when the 2nd resin B reaches partition member 30a, since the solidification of the 1st joint portion 17a is completed,
After 1st injection molding portion is molded the 1st Resin A, the injection molding without waiting for the 1st Resin A is completed, and the 2nd injection molding portion can be molded the 2nd resin
B.Therefore, it is possible to the synthetic resin shortened the time required to providing forming.
In addition, the opportunity that the 2nd resin B reaches partition member 30a can be according to the cast gate from mold to separation of the invention
Position until component 30a and protrusion 16b and suitably change, but the portion by making at least correspond to the 1st joint portion 17a
The curing ratio of position shifted to an earlier date in the past, can shorten injection molding cycle, and also improved the degree of freedom of mold design (design).As
Molding cycles, with the design of identical mold, comparison is applicable in the component of the present invention and previous component, can shorten such as 3 seconds.
So shaped running channel R is as shown in Figure 4, is formed in a part of the wall portion 17a1 by the 1st joint portion 17a
Curved face part is embedded with the second joint portion 17b of cylindrical shape corresponding with the shape of partition member 30a.That is, the 1st joint portion 17a is formed
