The specific embodiment:
Below in conjunction with the making of accompanying drawing and panel shell of television, two kinds of intake method design and processes are described in detail.
At first by using the flow equilibrium of Mold-flow software analysis product, thereby the size of determining mold runner and advancing cast gate (as shown in Figure 3, wherein, 3 for sprue, 4 for runner, 5 for gate shape: it is various to advance to water gate shape, commonly used has only two kinds of illustrated latent cast gate and banana-shaped) design; Each runner and advance the cast gate pressure balance during again by the filling of Mold-flow analytic product, determine the feasibility of sprue air inlet, when each runner and advance the cast gate pressure divergence hour (shown in the accompanying drawing 3, the pressure of cast gate induction part is 47.4Pa, the pressure of runner is 48.5Pa, differ smaller), meet gas and chew the air inlet principle, can design gas and chew air inlet;
After having determined that gas is chewed air inlet, as shown in Figure 4, change the size of part runner 6 again by the mold-flow software test, analyze its flow equilibrium and pressure balance, it is changed, the pressure divergence that at this moment respectively advances cast gate can increase (as Fig. 4, the pressure of cast gate induction part is 57Pa, the pressure of runner is 47.7Pa), air tube 2 can be positioned near advancing (as shown in Figure 5) cast gate of pressure maximum this moment, be designed to air tube 2 air inlets.
Channel size changes in an embodiment of the present invention can be by changing mold runner flow regulating valve (being mold insert) (accompanying drawing 6; Interchangeable flow regulating valve is changed process: unclamp screw 7 earlier, mold insert 8 is pulled down from CORE 9, and mold insert 8 is inverted, and the mold insert runner 10 becomes after 11 from the cross section, by positive and negative countersunk head screw hole 12, screw 7 is re-installed in and finishes the replacing process on the CORE 9 with mold insert 8) realize.
As shown in Figure 6, the basic configuration of mold insert is the square structure with four arc turnings, its former and later two surfaces are not provided with corresponding to the gentle runner hole 10,11 of chewing air inlet of air tube air inlet, wherein air inlet is chewed corresponding to gas in this runner hole 10, its size is consistent with the channel size on the mould, runner hole 11 is corresponding to the air tube air inlet, and its undersized is in the size of mould upper runner.
Be applied in the concrete injection moulding production at this mold insert, its processing step is: 1, after the mould installation, the nitrogen inlet interface is penetrated at injection machine and is chewed or do not penetrate at injection machine and chew, and chews air inlet or air tube air inlet by gas; 2, mould die sinking on lathe checks that the runner accent flows the state of mold insert; 3, chew air inlet by gas and then flow regulating valve is changed to the 10 cross section states of the runner hole shown in the accompanying drawing 6, this runner hole 10 contacts with the runner of mould; Then flow regulating valve is changed to the cross section state in the runner hole 11 shown in the accompanying drawing 6 by the air tube air inlet, if original mold insert can not satisfy production, also the accent of replaceable other different cross section stream mold insert is produced just can adapt to the situation of injection machine.
Because mold insert is removable accessory, it can be according to the mold insert in the supporting suitable runner of the situation hole of using, to be suitable for concrete requirement of producing.
In concrete application process, promptly in other the embodiment, the channel size that can also be designed to other is adjusted mode, as:
1, do not adopt interchangeable mold insert, but runner is directly formed to the identical runner form behind the mold insert of changing; Runner is directly formed to a kind of captured area 13 (shown in Figure 7), and its controllable pressure limit is very little, seems narrow than interchangeable its production technology of accent stream mold insert.
2, do not adopt interchangeable mold insert, on runner, install and transfer stream screw 14 (shown in Figure 8); Use screw to regulate runner local size (accompanying drawing 8), its runner tunable performance is relatively low, and injection pressure control effect is poor with respect to interchangeable accent stream mold insert.
3, do not adopt interchangeable mold insert, cylinder control system control runner size (shown in Figure 9) is installed on runner.When oil cylinder pull bar 15 is mobile to the left or to the right, trapezoid block about 17 is movable, driving movable block 16 moves up and down, thereby regulate local channel size (accompanying drawing 9), its control effect for injection pressure is very good, even surpasses interchangeable accent stream mold insert, but its complicate fabrication process, cost is very high, does not generally adopt.
Method for designing of the present invention and technology are applicable to face-piece series products single channel, the design of multithread road; Also can be applicable to manufacturing other injection moulding face-piece series products (as: LCD TV face-piece, LCD face-piece, computer monitor face-piece, rear-projection face-piece, panel; Also have washing machine, refrigerator etc.).
The die design schemes that the same mould of the present invention possesses two kinds of air inlet methods (air tube air inlet gentle chew air inlet) is considered the production adaptability of gas-assist mold, solve the one-to-one relationship of intake method and gas assistant formation equipment by the mould design, the difference that has solved owing to intake method causes the device therefor production technology difference that causes also inequality, the inharmonic problem of injection moulding resource.On the basis of single intake method mould, adopted two kinds of designs that intake method possesses, improved the production adaptability of gas-assist mold greatly, make full use of the injection moulding resource, make things convenient for the scheduling and the production schedule arrangement of mould, reduce cost.
