Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model mould circular arc side picking device embodiment is described further.
A kind of mould circular arc side picking device, comprise moving platen 1, the interior semicircular switch block 11 of described moving platen 1, switch block 11 is semicircular, and switch block 11 is embedded on moving platen 1.Switch block 11 is above provided with die cavity 12, and after solid plate and the mutual matched moulds of moving platen 1, the cast gate of injection machine, to injection moulding in die cavity 12, defines the bend pipe tools of 180 degree.Core 3 is equipped with in die cavity 12, switch block 11 is connected with actuating unit below, and core 3 is fixing, and die cavity 12 inwall is provided with the outer line consistent with pipe fitting, therefore the pipe fitting of the injection mo(u)lding when relative motion occurs for both can rotate along with switch block 11, deviates from from stationary core 3.
Described moving platen 1 is provided with the driving mechanism taken out for side, described die cavity 12 is positioned on described switch block 11, described driving mechanism comprises the slideway 21 fixing with moving platen 1, is fixed on the first hydraulic cylinder 22 on described slideway 21, the piston rod of described first hydraulic cylinder 22 is connected with the crushing block 23 for fixing described switch block 11.When locked mode, first hydraulic cylinder 22 drives crushing block 23 to press this rotor, make it be fixed on moving platen 1 and there will not be displacement, and when die sinking, crushing block 23 is subject to the driving of the first hydraulic cylinder 22, slide toward the direction away from moving platen 1 along slideway 21 and move, so just reserved space to rotor, actuating unit rotor driven rotates.
As shown in Figure 2, the shape of core 3 is made up of the elbow of 180 and a straight-bar, and the part of elbow is positioned at die cavity 12, for processing plastic.One end of described core 3 upper straight rod is fixedly connected with described slideway 21, the straight bar part of described core 3 runs through described crushing block 23, described crushing block 23 is provided with the mold insert 24 for sealing described die cavity 12, described mold insert 24 quantity is two, two mold inserts 24 are sealed up from the position at two of pipe fitting die cavity 12 respectively, one of them mold insert 24 is provided with a dop 241 above, dop 241 penetrates die cavity 12, this mold insert 24 is by dop 241 and described core 3 one end inlay card, other end mold insert 24 is enclosed within outside described core 3, when die sinking, two mold inserts 24 all drive disengaging rotor by crushing block 23, penetrate when matched moulds in the die cavity 12 of rotor.
Described switch block 11 is semicircle, and bottom circle centre position is connected with rotating shaft 44 described in rotating shaft 44 is provided with gear 41, be provided with the tooth bar 42 engaged with described gear 41 in described moving platen 1, described tooth bar 42 be connected with the second hydraulic cylinder 43, described second hydraulic cylinder 43 is fixed on described moving platen 1.
The course of work of this mould is as follows: injection machine carries out injection moulding to the die cavity 12 in cast gate, in the process of injection moulding, after injection moulding completes, when die sinking, first hydraulic cylinder 22 drives crushing block 23 to drive insert to release on the upside of switch block 11, transfers to outside along slideway 21 together with the straight-bar of core 3.Second motion of hydraulic cylinder 43 with carry-over bar 42 afterwards, driven wheel 41 rotates, and drives switch block 11 to rotate by rotating shaft 44, and in switch block 11 die cavity 12, the product of inlay card is subject to the drive of switch block 11, is separated, drops out above the core 3 of stationary state.In the process of matched moulds, crushing block 23 props up switch block 11, guarantees that switch block 11 can not be shifted in the process of rotating, plays locked mode effect.
Original core 3 rotation is changed over die cavity 12 rotate, due to the small volume of rotor, after stripper plate is removed, rotor just can be subject to actuating unit to be affected rotation and comes, avoid the structure originally rotated by core 3, comparatively speaking shared volume can greatly reduce, and can install the operating efficiency that injection machine strengthened greatly by more mould on same frame injection machine.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
