Description
The present invention relates to a kind of plastic mould with formation pivoted position, particularly a kind of have two members that can pivot mutually, and the plastic mould that can utilize ejection formation to use.
Goods such as existing zipper head, its pulling-on piece forms and can pivot sliding part, and therefore, it utilizes plastic mould to penetrate the system sliding part earlier, and then metal pulling-on piece is embedded sliding part, so constitutes a pull head, and its pulling-on piece sliding part pivot relatively.
This kind is provided with the finished product that two members can pivot mutually, but as a kind of finished products such as pull heads with two pivot members, it just needs to finish finished product by the procedure of complexity, and its finished product is in the interlocking position, at least by a member leaving certain gaps uncovered by the economic plan, make the just expansible elasticity of body of its Available Material, make the interlocking and the closure of distortion, relatively, also have the problem of coming off between member.
The Taiwan patent gazette is announced " manufacture method of injection plastic cement formula zipper head " patent case No. 160989, die component 13 by a pair of complementation, 14, its boundary becomes first die cavity 22,23 to form pull head body 1,26, second die cavity 23,33 to form pulling-on piece 2,28, first, second die cavity 22,23,32,33 interconnect, by a main sliding die heart 15,30 are disposed at first die cavity 22 slidably, 32, and has an auxiliary sliding die heart 16,31, main, the auxiliary sliding die heart 15,30,16, the shape of 31 common formation one and pulling eye 18 complementations, the auxiliary sliding die heart 16,31 can be moved to primary importance to block first, second die cavity 22,23,32,33, and move to the second place so that first, second die cavity 22,23,32, be communicated with between 33, therefore, the plastics gradation is penetrated, and has pivotable pulling-on piece 2 with formation, 28 and body 1,26.Therefore, though this kind penetrated pivotable two members that molding jig can be formed with integral type, it is made still need expend the more time, and forms a plurality of pull heads can't multi-point mould the time.
The object of the present invention is to provide a kind of plastic mould with formation pivoted position, it has two members that can pivot mutually, can be one-body molded with injection molding method, and two members have movable pivot each other by mould, and can a modulus cave fast, a large amount of moulding.

The four module 4 and second module 2 are incorporated into male model 6, the four modules 4 and establish lower pulling chamber 41, with the pull-down section of the lower pulling chamber 31 common moulding pulling-on pieces of the 3rd module 3.Four module 4 itself is established two guide grooves, 42, two guide grooves 42, and each is inserted for a guide block 43, and guide block 43 slides according to guide groove 42, makes the module 44 that is incorporated into two guide blocks 43 can do approaching amplexiform or separately, and with two modules 34 of the 3rd module 3 near or separate.Module 44 is provided with die cavity towards the three-dimensional space, be respectively the back and go up connecting ring cave 47 on pterion 45, the processus aboralis ear acupuncture point 46, the back, pterion 45 communicates with the tie-beam cave 24, back and the processus aboralis ear acupuncture point 46 on the back, 47 in connecting ring cave does not communicate with the back upward pterion 45 and the processus aboralis ear acupuncture point 46 on the back, but the back connecting ring cave 47 of going up of two modules 44 interconnects, and more can with the preceding last connecting ring of going up connecting ring cave 37 and synthesis type pulling-on piece of the 3rd module 3; Four module 4 itself is provided with away hopper 48, in order to the plastics of fusion are delivered to each hole, cave.
See also shown in Fig. 2,3,4, it shows that first module 1 of the present invention combines with the 3rd module 3, and second module 2 combines with four module 4, and the situation of the module of two groups of combinations when becoming separately.
See also Fig. 5,6, shown in 7, it shows first module 1 and the 3rd module 3 and second module 2 and the four module 4 and the fashionable situation of combination, therefore, this mould is formed with the lower wing cavity 13 of moulding bottom wing 71,23, be formed with the tie-beam cave 14 of moulding tie-beam 72,24, be formed with the last pterion 35 of moulding upper limb 73,45, be formed with the lug cave 36 of moulding lug 74,46, be formed with the last connecting ring cave 37 of the last connecting ring 75 of moulding pulling-on piece, 47, and the lower pulling chamber 31 that is formed with the pull-down section 76 of moulding pulling-on piece, 41, therefore, the plastics of fusion can enter to each cave hole forming when walking hopper 48 and infeed.
See also Fig. 8; the preferred embodiment of a mould of the present invention shown in 9; this mould includes master mold 5; male model 6; and should public affairs; master mold 6; 5 are respectively equipped with four modules; master mold (group) 5 is fixed in the holder of Jet forming machine by master mold substrate 51; master mold (group) 5 has a portable plate 52 to be subjected to flexible member 53 pushing tows; make portable plate 52 perseverances that the strength of unlatching be arranged; establish batter post 54 at master mold substrate 51; batter post 54 terminals are overlapped a slide block 55; it is mobile that slide block 55 is driven on batter post 54 by portable plate 52; and slide block 55 guide block 33 that can be pulled moves, and two modules 34 that are combined in two guide blocks 33 can be become separately or approaching, as shown in figure 10.
Male model (group) 6 is fixed in the mobile seat of Jet forming machine by male model substrate 61; male model (group) 6 has a portable plate 62 by flexible member 63 pushing tows; make portable plate 62 perseverances that the strength of unlatching be arranged; establish batter post 64 at male model substrate 61; batter post 64 terminals are overlapped a slide block 65, and slide block 65 is driven on batter post 64 by portable plate 62 to move, and slide block 65 guide block 43 that can be pulled moves; two modules 44 that are combined in two guide blocks 43 can be become separately or approaching, as shown in figure 10.
See also shown in Figure 10, when male model 6 and master mold 5 closures, four module 34,44 is mutually adjacent amplexiforming, and its each hole, cave becomes corresponding corral to become the hole, moulding cave of a pull head and pulling-on piece, it can be injected the plastics of fusion by the mouth 56 that shoots material of master mold 5, the pull head that contains pulling-on piece with the system of penetrating, because forming the last connecting ring cave 37,47 of pulling-on piece does not communicate with lug cave 36,46, and it is respectively walked hopper 25,48 and comes moulding saddle body and pulling-on piece, as shown in Figure 1, therefore, after the plastics solidification moulding, pulling-on piece promptly can pivot in moulding lug 74 positions of saddle body.
Pull head mould of the present invention, owing on the male and female mould, the array module can be set, therefore, promptly can finish several pull heads simultaneously by an ejection formation, and it only promptly can finish the system of the penetrating work that the mold closing system of penetrating, die sinking are taken out finished product by the single on-off action of male and female mould, on the whole, speed of production can become multiple to increase, and the pull head of the system of penetrating also can one-body moldedly have pulling-on piece and saddle, therefore, and the long-term problem of coming off that also do not have of using of pulling-on piece.
