Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of left and right line position loose-core injection mould, comprise front template 1 movable up and down and fixing rear pattern plate 2, on front template 1, have sprue gate 8, between described front template 1 and rear pattern plate 2, have the die cavity 4 of form fit moulding main body 3, the side of described front template 1 is connected with shovel 5, the oblique outer side-lower in shovel inclined-plane 51 of wherein said shovel 5, the below of described shovel 5 is provided with the slide block 6 that can horizontally slip, described slide block 6 upper ends are provided with the slide block inclined-plane 61 matching with shovel inclined-plane 51, described slide block 6 is between rear pattern plate 2 and shovel 5, described slide block 6 is provided with sensing moulding and buckles 31 core_pulling pole 41.Between die cavity, concrete ranking can be determined according to the feature of product, generally can arrange layouts single or two rows, and the ranking on mould of each die cavity 4 is same direction.Mold base between front template 1 and rear pattern plate 2 is designed with the headspace for shovel 5 activities, and front template 1 generally has four guide pillars, has fortune water pipe 9 in mold base, and wire casing headspace has screw hole; There is the running gate system at runner and sprue gate 8 at mold base center; When Mold Making, can at front template 1 and rear pattern plate 2, air discharge duct be set as required.
As a preference, the arranged outside of described rear pattern plate 2 has baffle plate 7, and described slide block 6 one sides are provided with the guide post 71 that points to and pass baffle plate 7, on described guide post 71, are set with spring 72.
As a preference, the position of the corresponding moulding main bodys 3 in described die cavity 4 inner sides is provided with thimble 42, with prevent electric wire in die cavity under injection pressure effect, there is off normal phenomenon.
As a preference, between described front template 1 and rear pattern plate 2, the position of corresponding moulding wire ends 32 is provided with front mould wire casing 43, rear mold wire casing 44, contact-making surface between described front template 1, rear pattern plate 2, front mould wire casing 43 and rear mold wire casing 44 is provided with adhesive layer, ensure that electric wire ranking and sizing material melt in mould can not overflow from die cavity 4, are beneficial to form the product that quality is intact.
As a preference, described die cavity 4 be built-in with for moulding buckle 31 insert 45, mainly for buckling 31 through hole at die joint place moulding, also can direct demold.
In the time of actual production, its step is as follows:
1) be ready to produce required electric wire;
2) die assembly above corresponding injection machine, regulate injection moulding temperature used, pressure, the time is waited until processing parameter;
3) mould accessory is assemblied in mould, then electric wire is put into die cavity 4 and front mould wire casing 43 and the rear mold wire casing 44 of mould, start power supply and operate matched moulds;
4) front template 1 and shovel 5 thereof move down, and promote slide block 6 and move to the inside under the effect of spring 72, and core_pulling pole 41 contacts completely with core.
5) after matched moulds, sizing material is injected to mould from the barrel of injection machine, and sizing material is via the sprue gate 8 of mould, flow to sprue and the runner of running gate system, flow to die cavity 4 by cast gate again, in this process, because sizing material is own through heating, enough fusing sizing materials of oneself warp of temperature, when sizing material melt flows in die cavity 4, under the effect due to fluid, sizing material melt is promptly filled in full die cavity 4, then the sizing material of plasticizing is stablized under pressurize at die cavity 4, gradually forms the product of type cavity mould.
6) when oneself carries out parting after reaching the time of design, front template 1 and shovel 5 thereof move up, and promote slide block 6 and move laterally under the effect of spring 72, drive core_pulling pole 41 outwards to move simultaneously, core_pulling pole 41 separates completely with core, at this moment just completes the effect of parting; , insert at front mould and rear mold, moulding buckles 31 through hole directly can carry out parting from die joint meanwhile, direct parting in the time that front mould moves up.
7), simultaneously in injection moulding process, because injection mould has fortune water pipe 9, cooling water can make the temperature of mould be down to 40 °～60 °, and molten melten gel body can promptly be solidified in die cavity;
8) take out oneself curing product and then from mould, then repeat above operation and carry out discontinuous running.
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.
