Detailed description of the invention
Fig. 1-6 is depicted as related description figure of the present invention; A kind of double cast gate is in conjunction with running gate system injection mold, comprise in sprue bush 1, upper clamping plate 2, slip A plate 3, spacing controlling organization 4, indent and take out slide block 5, indent mold insert 6, core 7, dynamic model B plate 8, mould pin 9, counterdie seat board 10, thimble cover plate 11, thimble push plate 12, rubbish nail 13, limited block 14, thimble 15, support column 16, die cavity guide pillar 17, die cavity guide pin bushing 18, release link 19, buckle slide block 20, elastic plastic 21, T-slot tapered wedges 22, bearing type die set guide pin 23, mould bases guide pin bushing 24, as shown in Figure 4.
Described spacing controlling organization 4 is installed on upper clamping plate 2, slip A plate 3, dynamic model B plate 8 in order to control the sequential mold opening between three blocks of plates; T-slot tapered wedges 22 is installed on upper clamping plate 2, drives the motion of taking out slide block 5 in indent; Buckle slide block 20 is installed on dynamic model B plate 8, for the side core-pulling to product buckle; Limited block 14 is installed on push pedal cover plate, controls product and ejects distance; Bearing type die set guide pin 23, mould bases guide pin bushing 24 are for controlling the reset of mould bases; Die cavity guide pillar 17, die cavity guide pin bushing 18 for controlling and ensure the accuracy that die cavity resets, as shown in Figure 5.
Described mold cooling system is Pipeline Water cold type cooling system, pipe diameter 8mm; Sprue bush 1 adopts three template dies to fill with mouth formula sprue bush; Mold parting surface is two-time parting face mode.
The structure composition of described spacing controlling organization 4 comprises spacing and controls cutting 25, B plate locking plate 26, croze 27, cutting block 28, mobile horizontal bolt 29.Its installation situation is that spacing control cutting 25 is installed on top clamping plate, and croze 27, cutting block 28 are installed on A plate, and B plate locking plate 26 is installed on dynamic model B plate, and mobile horizontal bolt 29 is installed in croze 27, as shown in Figure 6.
Described mould structure adopts false Three-board-mould structure, and Design of Runner System adopts secondary casting program, and one-level cast adopts Subsidence pouring, and secondary adopts U-shaped flow passage side cast gate mode, as shown in Figure 2.
Described mold layout is that a mould goes out two chambeies, as shown in Figure 3.
During real work, as shown in Fig. 4, Fig. 5, Fig. 6, its motion operation principle is as follows:
1) mould somatotype control structure parts as shown in Figure 5, and its composition situation is upper clamping plate, A plate, B slab core die cavity guide pillar guide pin bushing, guide-post of die-set guide pin bushing, fixed-distance controller, lower link bar, elastic plastic.Spacing controls mainly to implement separation between upper clamping plate, A plate, B plate and controls, be mainly used in PL1 die joint, PL2 die joint separately;
2) first time somatotype between top clamping plate and A plate, i.e. PL1 die joint in Fig. 5, because T-slot tapered wedges 22 is installed on top clamping plate, can not move, therefore after the first somatotype opens, T-slot tapered wedges 22 is driven in indent by T-slot and takes out the core_pulling demoulding of slide block 5 to inner core pulling product I, II position;
3) second time somatotype is between A plate and B plate, i.e. PL2 die joint in Fig. 5; During second time somatotype, the Angle Pin sliding block core-pulling mechanism dynamic model side slide at product 1,2,3,4 place is being positioned under the Angle Pin effect on A plate, and band movable slider realizes the side core-pulling of snapped-in position everywhere.
Mold actions process comprises following step:
1) the opening of PL1 die joint, after injection moulding cooling, mould is opened, upper clamping plate 2 and slip A plate 3 are pushed open by elastic plastic 21, and A plate, under fixed-distance controller controls, retreats with dynamic model B plate, take out slide block 5 in indent under the effect of T-slot tapered wedges 22, realize loosing core action;
2) PL2 die joint is opened; A plate, B plate have the clamping mechanism between two plates to control to take out in indent after slide block 5 realizes loosing core; rushed open by the set of fixed-distance controller; realize the separation of A, B plate, the time of releasing, A plate continues to retreat with B plate; after slow astern segment distance; A plate is fastened to be held with the lower link bar on top clamping plate, can not continue to retreat with dynamic model B plate again, thus realize the somatotype of PL2.
Fig. 6 is the structure chart of spacing controlling organization 4, and in figure, each part is that spacing controls cutting 25, B plate locking plate 26, croze 27, cutting block 28, mobile horizontal bolt 29; Its installation situation is that spacing control cutting 25 is installed on top clamping plate, and croze 27, cutting block 28 are installed on A plate, and B plate locking plate 26 is installed on dynamic model B plate, and mobile horizontal bolt 29 is installed in croze 27;
Its operation principle is: during first time somatotype, A plate, B plate pin by mobile horizontal bolt 29 and B plate locking plate 26, until first time somatotype after, slip A plate 3 continues mobile with croze 27, cutting block 28, mobile horizontal bolt 29 together, until croze 27 hits by spacing control cutting 25 bottom boss position hit the left side from the right, thus the locking that mobile horizontal bolt 29 and B plate locking plate 26 are formed is opened, realize the separation of A plate, B plate.
3) when resetting, mould present PL2 die joint place closes, and be then that PL1 closes, last mould is completely closed, waits for the beginning of next injection cycle.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
