What need stress is; When first module 300 and second module 400 are closed mutually; Because two positioning ribs 130 of each coupling 100 are by corresponding two locating pieces, 340 clampings; Therefore, the body 110 of each coupling 100 soars in enclosure space 460, and the body 110 that means each coupling 100 does not contact the surface of first die cavity 310 and second die cavity, 410 die cavitys.
In addition, when first module 300 and second module 400 were closed mutually, the thimble 452 of the 4th grooving 450 stretched to second 502 of plate body 500, and inserts in the corresponding location indentations 520.So; Because above-mentioned collar flange 331 is resisted against first 501 of plate body 500; Add that thimble 452 is resisted against second 502 of plate body 500, make two opposite faces of plate body 500 be against between thimble 452 and the collar flange 331 by folder simultaneously, and then firmly be positioned in the enclosure space 460.
Step (404) is injected in the enclosure space 460 of a sizing material to injection forming mold 200, coats plate body 500 and coupling 100 (Fig. 6) with part:
In this step; Start a glue filling device (not shown); Make the sizing material that glue filling device injects high temperature and is in a liquid state via 451 pairs of enclosure spaces of adhesive pouring nozzle 460; (be convenient to flow in the enclosure space 460, till filling with enclosure space 460 by Fig. 6, this sizing material less than the fusing point of this plate body and those couplings for the fusing point of colloid.Sizing material can be according to the shape of enclosure space 460 after being injected into enclosure space 460; To form the colloid 710 (Fig. 7) of correspondingly-shaped after the curing; And above-mentioned plate body 500 and coupling 100 all eligibly partly be coated in the colloid 710, and its reason is (Fig. 2 A and Fig. 6) as follows:
322 on post passes because the connecting hole 121 of each coupling 100 is positioned, and therefore, the body of each coupling 100 110 is unlikely to be impacted and move towards its X-direction by the sizing material that flows; Because two positioning ribs 130 of each coupling 100 are by corresponding two locating pieces, 340 clampings, therefore, the body of each coupling 100 110 is unlikely to be impacted and moves towards its Y direction by the sizing material that flows; Because when first module 300 is closed mutually with second module 400; Make these a little positioning ribs 130 of each coupling 100 be positioned respectively in the second corresponding storage tank 440; Therefore, the body 110 of each coupling 100 is unlikely is impacted and moves towards its Z-direction by the sizing material that flows.So, the body 110 of each coupling 100 can intactly be coated in the sizing material.In addition, because two opposite faces of plate body 500 are against between thimble 452 and the collar flange 331 by folder simultaneously, therefore, plate body 500 is unlikely to be impacted and the unexpected directions of court move by the sizing material that flows.
Step (405) is opened first module 300 and second module 400, and takes out semi-finished product 600:
Referring to shown in Figure 7.Fig. 7 is in the partial schematic diagram of semi-finished product 600 of the present invention behind the injection forming mold 200 that breaks away from the 2nd figure.
