High production efficiency.
Figure 14-16 is please referred to, the stitch 11 after cutting off enters injecting mechanism 27 and is molded, specifically, the note
Molding machine structure 27 includes upper mold 271 and lower die 272, and the face that lower die 272 and upper mold 271 are docked is provided with the first type chamber 273, upper mold
271 and the face docked of lower die 272 on be provided with second type chamber 274, when upper mold 271 and lower die 272 are docked, 273 He of the first type chamber
Second type chamber 274 cooperatively forms the type chamber of forming plastic cement ontology 12.Injecting hole 275 is provided in upper mold 271, injecting hole 275 connects
Logical second type chamber 274, when injection molding, plastic cement flows into second type chamber 274 by injecting hole 275.
First type chamber 273 includes stitch portion 2731 and body part 2732, the both ends of stitch 11 after stitch 11 above-mentioned is cut off
It is set to stitch portion 2731, the limiting section 111 of stitch 11 is set to body part 2732.The width in stitch portion 2731 is just to accommodate
The width of stitch 11, when injection molding, plastic cement flows into body part and wraps up the limiting section 111 of stitch 11, and 11 limiting section of stitch
The part at 111 both ends then exposes.
Please refer to Figure 17-18, it should be noted that die holder 251 above-mentioned is provided with the face of the first protrusion 2511 and described
The lower die 272 of injecting mechanism 27 is bonded setting, and the surface that the lower die 272 is provided with the first type chamber 273 is the molding of lower die 272
Face 2721, the forming surface 2721 are slightly less than the second joint face 2513 setting of the die holder 251, and difference in height H, then stitch 11 exists
Cutting mechanism 25 is fallen into the first chamber 273 of lower die 272 after cutting off immediately wait be molded.The design method is by 25 He of cutting mechanism
Injecting mechanism 27 integrates setting, so that coil brace molding machine 20 is compact-sized, further, cutting and injection molding two
Road technique convergence time is short, has shortened the molding time of coil brace 10, has improved production efficiency.
Also referring to Fig. 1-Figure 19, the positioning mechanism 29 can be a plate body, which is set to injection molding
Side of the mechanism 27 far from cutting mechanism 25.When coil brace 10 forms, stitch 11 transports through cabling channel by thread feeding mechanism 20a
2413 and through slot 2514 until stitch 11 one end by positioning mechanism 29 withstand completion positioning, at this point, the first molding die 242 press
It overlays on wiring board 241, the molded part 2431 on the second molding die 243 passes through the molding hole 2414 and the first molding die
Forming tank 2421 on 242 forms cooperation and stamps out the limiting section 111 to stitch 11.Simultaneously or later, cutter 252 is matched
The raised 2511 pairs of stitch 11 of first be arranged on molding seat 251 are cut off, and the stitch 11 after cutting falls into injecting mechanism 27
In first type chamber 273 of lower die 272, the upper mold 271 and lower die 272 of subsequent injecting mechanism 27 are molded, note of the plastic cement from upper mold 271
Mole 275 flows into the chamber that upper mold 271 and lower die 272 are formed, and completes the package to 11 limiting section 111 of stitch.Last upper mold
271 and lower die 272 be opened, thimble (not shown) ejects molding coil brace 10, that is, complete entire coil brace 10 at
Type technique, move in circles uninterrupted production.It is appreciated that the stitch 11 of first cutting is without limiting section 111, coil
The molding of bracket 10 can be started by second.
In the present invention, punching mechanism 24, cutting mechanism 25 and injecting mechanism 27 are integrally disposed upon coil brace molding dress
It sets inside 20 shaping mechanism 20b, also the molding technique of hardware and injection molding process is integrally disposed in a device
Face.Specifically, die holder 251 and the fitting setting of wiring board 241, and the of the second joint face 2513 of die holder 251 and wiring board 241
One mating surface 2411 is concordant, and the through slot 2514 on cabling channel 2413 and die holder 251 on wiring board 241 is corresponding, and stitch 11 exists
Cutting, further, die holder 251 are completed at the first joint face 2512 of die holder 251 immediately after completing punching press on wiring board 241
The first joint face 2512 and the lower die 272 of injecting mechanism 27 be bonded setting, that is, the stitch 11 after cutting falls into lower die
Wait be molded in 272 the first type chamber 273.Punching mechanism 24, cutting mechanism 25 and injecting mechanism 27 are located next to by the set-up mode
Setting, the linking of each mechanism is compact, and punching mechanism 24, cutting mechanism 25 and injecting mechanism 27 integrate design, then coil branch
When frame 10 forms, without dividing two-stage process to carry out, the molding time of coil brace 10 is shortened, can carry out automating continuous life
It produces, improves production efficiency.And the linking of short period may be implemented in the running between each mechanism, is effectively shortened each molding
The time required to process section, production efficiency is further improved.
Further, since hardware moulding process and injection molding process is integrally disposed, pass through punching mechanism 24, cutting
Mechanism 25, injecting mechanism 27 and positioning mechanism 29 are reasonably arranged, so that the structure of whole-set coil rack forming device 20 is non-
It is often compact, effectively reduce the space occupied of the device.
Figure 20 is please referred to, the third embodiment of the present invention provides a kind of coil brace forming method S20, the coil brace
Forming method S20 includes the following steps：
Step S201：Line sending, thread feeding mechanism 20a is by stitch 11 through wiring board 241 according to the technological forming sequence of stitch 11
Transport stitch 11；
Step S202：Second molding die 243 of punching press, punching mechanism 24 is mobile toward 242 direction of the first molding die, the
The molded part 2431 that is arranged on two molding dies 243 cooperates the forming tank 2421 that is arranged on the first molding die 242 by stitch 11
Strike out 111 shape of limiting section；
Step S203：The cutter 252 of cutting, cutting mechanism 25 is mobile toward 251 direction of die holder, and cutter 252 cooperates die holder 251
The raised 2511 pairs of stitch 11 of the first of upper setting carry out thrusting required length；And
Step S204：Injection molding, the stitch 11 after thrusting enter injecting mechanism 27, the upper mold 271 and lower die of injecting mechanism 27
272 moldings, plastic cement flow into forming covered limit in the chamber that upper mold 271 and lower die 272 are formed from the injecting hole 275 of upper mold 271
The plastic body 12 in portion 111.
Wherein, before S201 step, further comprise the steps：
Step S2011：Positioning is located at injecting mechanism 27 to stitch 11 before stitch 11 carries out punching press, cutting and injection molding
Side far from cutting mechanism 25 is positioned.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in original of the invention
Made any modification within then, equivalent replacement and improvement etc. should all be included in the protection scope of the present invention.
