The beneficial effects of the utility model are: this mould is by rational structural improvement, for the feature of multi-thread row's formula plug, main mould and a point module is adopted to match, realize arranging multiple wire rod in a cave die cavity, and this mould can carry out replacing flexibly and accurately locating to the product in die cavity for various product, ensures injection moulding quality and efficiency.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 6, a kind of multi-thread row's split locate mode mould, comprise the active template 1 of top and the main solid plate 2 of below, initiatively template 1 and main solid plate 2 form main mould.Die cavity 3 is provided with between described active template 1 and main solid plate 2, described die cavity 3 comprises for the rear mold bar group 31 of injection moulding net tail bayonet slot 4 with for module 32 before injection moulding net tail body 41, wherein have bayonet slot die cavity in rear mold bar group 31, front module 32 has net tail die cavity.Rear mold bar group 31 and front module 32 split-type design are conducive to replacing as required, and rear mold bar group 31 is connected by screw with front module 32.The rear and front end of described die cavity 3 is respectively arranged with front channel mould group 51 for Positioning Power line 5 and rear wire casing module 52, and front channel mould group 51 and rear wire casing module 52 can be replaced according to the concrete gauge size of power line 5 equally, also follow main mould equally to divide upper and lower mould.The front of described main solid plate 2 is provided with point module 6 for injection moulding subnetting tailpiece 42.As a preference, described point of module 6 includes the parting moving platen 61 of top and the parting solid plate 62 of below, the front end of wherein said parting solid plate 62 is fixedly connected with fixed head 63, be provided with regulating base board 64 between the lower end of described fixed head 63 and main solid plate 2, described fixed head 63, connected by adjusting nut 65 between regulating base board 64 and main solid plate 2.Parting moving platen 61 then controls by an independent controlling organization, also can link with the control structure of active template 1.
With reference to Fig. 1 ~ Fig. 5, between described front channel mould group 51 and the upper and lower mould of rear wire casing module 52, die joint place is provided with for the bit block 53 to position, for carrying out contraposition between front channel mould group 51 and the upper and lower mould of rear wire casing module 52.The bit block 53 of described front channel mould group 51 has wire casing 54, and than groove 54 better effects if that the channel mould group 51 that is directly at the front bursts at the seams, the rear end adduction of described wire casing 54 forms sealing mouth 55, reduces the chance that sizing material is excessive, affects injection moulding quality.
Being provided with between described main solid plate 2 and point module 6 can the rear clamp group 7 of translation, the front end of described point of module 6 is provided with front clamp group 71, and front clamp group 71 and rear clamp group 7 coordinate avoids the power line 5 at subnetting tailpiece 42 place in injection moulding process, occur dislocation.
When actual production, its step is as follows:
1. get out the electric wire needed for producing, carry out the sheath of outer stripping electric wire according to production technology.
2. die assembly above corresponding injection machine, regulate the temperature that injection moulding is used, pressure, the time waits until processing parameter;
3. the accessory die cavity main body of main mould, net portion, trunking is divided and is assemblied in mould, then electric wire is put into the accessory die cavity main body of main mould of mould, and net portion, in wire casing part, starts power supply and carry out operation matched moulds;
4. after matched moulds, sizing material is injected from the barrel of injection machine to mould, sizing material is via the main cast gate of mould, flow to sprue and the runner of running gate system, die cavity 3 is flowed to again by gum-injecting port, in the process, because sizing material is own through heating, temperature is own through enough melting sizing material, in the rear mold bar group 31 flowing to die cavity 3 when sizing material melt and front module 32 die cavity, due under the effect of fluid, sizing material melt is promptly filled in full die cavity, then the sizing material plastified, under the die cavity of rear mold bar group 31 and front module 32 carries out stable pressurize, gradually forms the product of type cavity mould.
5., simultaneously in injection moulding process, because injection mould has fortune water pipe, cooling water can make the temperature of mould be down to 40 DEG C ~ 60 DEG C, and melten gel body can promptly be solidified in die cavity;
6. after mould reaches the time of oneself design, initiatively template 1 automatically moves up, and the top roller of injection machine is by the top roller hole of mould simultaneously, takes flat thimble out of and moves up, and in die cavity, oneself have cured product and ejects driven handle, thus completes knockout course.
7. take out the product of oneself solidification and then from mould, then repeat above operation and carry out discontinuous running, product as shown in Figure 6.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
