Shown in Fig. 6,7, the injection mould mainly comprises water core 1, core rod 3a, core rod seat 8a, die lip 5a and die cavity 7; Core rod 3a is hollow cylindrical structure, is provided with water core 1 in core rod 3a hollow, and water core 1 center is an endoporus, and water core 1 is plugged on the solid central layer 2 by the face of cylinder, and water core 1 is mainly used in to logical cooling water in the die cavity.The outside at core rod 3a from left to right is provided with core rod seat 8a, die lip 5a and die cavity 7 successively; The moulding cylindrical so forming cavity of the endoporus of die cavity 7, die lip 5 and core rod 3a, die cavity 7 right-hand member centers are provided with fill orifice 12, and fill orifice 12 communicates with die cavity, is used for the plastics perfusion; Bottle base body 9 is shaped at die cavity.Core rod seat 8a left end is provided with boss structure, by the bolt that is provided with on the boss structure core rod 3 is fixed on the solid central layer 2; The first inner cone T2 of core rod seat 8a is enclosed within on the outer cone T1 of core rod 3, and the second inner cone S2 of core rod seat 8a is enclosed within on the die lip 5 left side outer cone S1, guarantees that die lip 5a is coaxial with core rod 3a endoporus; At solid central layer 2 right-hand members, the outside of core rod seat 8a is provided with push pedal 4, wearing plate 13 and slide plate 6 successively, promote slide plate 6 when wherein push pedal 4 is used for 9 demouldings of PET bottle base and move to right, and then die lip 5 moves to right; Wearing plate 13 is the oil-containing copper coin, is connected in the push pedal 4 with screw, can reduce the frictional force of skateboarding 6; Be provided with die cavity cover 14 on die lip 5a right side, the inner conical drogue of die cavity cover 14 is on the outer cone of the right side of die lip 5a, and die cavity 7 outsides are provided with solid chamber plate 11; Die cavity cover 14 blocks die cavity 7 by seam, and is fixed on the solid chamber plate 11 with screw, guarantees that die cavity 7 endoporus are coaxial with die lip 5a endoporus.The positioning action of 14 die cavitys 7 of die cavity cover is Gu chamber plate 11 plays fixedly die cavity 7 effects.Briquetting 15 is used for fill orifice 12 is fixed on solid chamber plate 11.The tapering of the inner conical drogue of the second inner cone S2 of the first inner cone T2, the second inner cone S2, die lip 5 left side outer cone S1, core rod seat 8, the right side outer cone of die lip 5 and die cavity cover 14 is 10-20 °.
(comparison diagram 3) as shown in Figure 8, the inner chamber of core rod seat 8a are C by cylindrical cavity, the first inner cone T2, length successively, and diameter is that the core rod seat inner hole surface and the second inner cone S2 of P constitutes.
(comparison diagram 4) as shown in Figure 9, it is N that die lip 5a designs the left part diameter, and the degree of depth is the die lip inner hole surface of E, and the inner hole surface right-hand member is provided with and highly is the bottleneck forming face of H; Die lip inner hole surface degree of depth E and bottleneck forming face height H sum are constant.
As shown in figure 10, (comparison diagram 5), it is M that core rod outer cone T1 right-hand member is provided with diameter, and length is the core rod middle circle cylinder of D, and core rod middle circle cylinder right-hand member is provided with counterbore G.
Length is C among the core rod seat 8a, and diameter is that core rod seat inner hole surface and the die lip 5a left end diameter of P is N, and the degree of depth is that the die lip inner hole surface of E leaves 0.01-0.05mm exhaust clearance, P=N; Core rod seat inner hole surface and die lip inner hole surface are positioned at the outside of core rod middle circle cylinder, cooperate in order not interfere moulding, all leave 0.10-0.30mm empty avoiding gap between core rod seat inner hole surface diameter P and die lip inner hole surface diameter N and the core rod middle circle cylinder diameter M; Highly be to form PET bottle base ridge between the bottleneck forming face of H and core rod 3a periphery among the die lip 5a.In order to make moulding not produce overlap, core rod middle circle cylinder diameter M is greater than bottleneck external diameter 3-6mm, and has a counterbore G in core rod middle circle cylinder right-hand member end.
In order to adapt to the bottleneck requirement for preparing differing heights, control die lip inner hole surface degree of depth E and corresponding core rod intermediate cylindrical face length degree D carry out Height Adjustment, as want the bottleneck height to increase, just reduce the value of die lip inner hole surface degree of depth E and core rod intermediate cylindrical face length degree D, as adjusting to 17mm by 21mm.
The present invention changes to core rod seat inner hole surface with the shaping area B that core rod seat 8 right-hand members shown in Figure 3 participate in the bottleneck end, and core rod seat 8a does not participate in the bottleneck moulding, and core rod seat 8a becomes a standardized element; Among core rod seat inner hole surface and Figure 10 among the core rod 3a diameter be M, length is that the core rod middle circle cylinder of D cooperates.It is N that die lip 5a designs the left part diameter, and the degree of depth is the die lip inner hole surface of E, and diameter is M among die lip inner hole surface and Figure 10, and length is that the core rod middle circle cylinder of D cooperates, and the axiality in the time of can guaranteeing the bottleneck injection moulding is convenient to again install.In the prior art, die lip does not directly cooperate the position with core rod, can adjust the bottleneck height H by changing die lip inner hole surface degree of depth E.
The present invention can change according to the bottleneck requirement for height, makes the die lip height overall constant, and promptly die lip inner hole surface degree of depth E and bottleneck forming face height H sum are constant.Length is D, diameter M be core rod middle circle cylinder mainly be with die lip 5a left part diameter be N, the degree of depth is that the die lip inner hole surface of E cooperates, its fit clearance also is the exhaust clearance of die lip, core rod seat, its exhaust is more smooth and easy, generally gets 0.15-0.25.
The present invention separates location dimension and compact dimensions on traditional die lip design of part basis, two parts are not interfered with each other.For the change of bottleneck size,, and need not change the core rod seat as long as change die lip, core rod.By changing die lip, core rod seat fit clearance, can make the exhaust space of mouth cylindrical part bigger, bottleneck is not easy grain raising; Because of the die lip height overall constant, can guarantee that the mould gross thickness is constant,, be beneficial to standardized production so do not need to change slide plate, the die cavity cover of supporting die lip and screw is installed when changing bottleneck, and be easy to mould and install adjust, help reducing manufacturing cost, simplified structure, reduction and safeguard mounting cost.
