Abstract
The present invention provides a kind of refrigerator decorative bar class injection mould of products runner flow control device, including injection mold, main running channel is horizontally arranged with injection mold, the both ends of main running channel are provided with and communicated with branch's running channel, be communicated with the middle part of main running channel vertically set enter running channel, also connected on the main running channel entered between running channel and branch running channel and adjusting rod positioning hole is set, slided in adjusting rod positioning hole and be provided with adjusting rod, adjusting rod is connected backwards to one end of main running channel by connector with the piston rod on cylinder, and piston rod is also set along the length direction of adjusting rod positioning hole.In a manner of substituting existing runner Flow-rate adjustment, solve existing way operation and is inconvenient, and the problem of efficiency is low.The invention belongs to injection molding art.
Description
Technical field
The present invention relates to a kind of injection mold flow control device, belong to injection molding technology field.
Background technology
The flow passage system of refrigerator decorative bar injection mould of products typically turns cold runner side gate using hot flow path, due to product chi
It is very little longer（500~800mm）, when design mould enters glue position and gate size, although carrying out mould stream with CAE mould stream softwares
Analysis, but many problems are still had when being actually molded, product is adjusted to qualified size using regulation injection parameterses
Product quality is also relatively difficult with improving, and is balanced to adjust the glue that enters of each cast gate, at present using in each runner
Place sets adjusting screw, is balanced to adjust into glue.With the change of environment（When being such as molded with different lathe and mold temperature
Change etc.）Regulation will be re-started, so, then regulative mode as using operates and is just inconvenient, and imitate
Rate is low.
The content of the invention
It is an object of the invention to：A kind of refrigerator decorative bar class injection mould of products runner flow control device is provided, with for
For existing runner Flow-rate adjustment mode, solve existing way operation and is inconvenient, and the problem of efficiency is low.
To solve the above problems, intend using such a refrigerator decorative bar class injection mould of products runner flow control device,
Including injection mold, main running channel is horizontally arranged with injection mold, the both ends of main running channel are provided with and communicated with branch's running channel, and master pours
Be communicated with the middle part of road vertically set enter running channel, setting regulation is also connected on the main running channel entered between running channel and branch running channel
Bar positioning hole, interior slide of adjusting rod positioning hole are provided with adjusting rod, and adjusting rod passes through connector and gas backwards to one end of main running channel
Piston rod on cylinder is connected, and piston rod is also set along the length direction of adjusting rod positioning hole.
In foregoing governor motion, the adjusting rod positioning hole is vertically installed in the downside of main running channel, and the width of adjusting rod
It is identical with the width of main running channel；
In foregoing governor motion, tracheae connector is provided with the tracheae of cylinder, tracheae connector is correspondingly arranged on electromagnetic switch
Valve, solenoid directional control valve are connected with socket by signal wire, and socket is connected with injection machine signal neutron.
Compared with prior art, the present invention is improved on the basis of existing mold so that in injection moulding process, can be passed through
Push-and-pull adjusting rod and then the cross-sectional area for adjusting the main running channel of injection, so as to adjust the flow of flow channel of injection die, realize mould stream
The uninterrupted or sequential adjustment of plastics stream in road, also can individually control to adjust a cast gate, or adjust simultaneously multiple
Cast gate, use is very convenient, drastically increases injection efficiency.
Brief description of the drawings
Fig. 1 is the main structure diagram of the present invention；
Fig. 2 be in Fig. 1 A-A to cross-sectional view；
Fig. 3 is to remove the overlooking the structure diagram after the mould of upper end in Fig. 2.
Embodiment
Embodiment：
As shown in Figure 1, Figure 2, Fig. 3 show a pair 1 and goes out 2 door frame panel moulds, and the mould enters glue using 4 side gates, is provided with 4
The governor motion integrated, is horizontally arranged with main running channel 2 in injection mold 1, and the both ends of main running channel 2 are provided with and communicated with point
Branch running channel 3, the middle part of main running channel 2 be communicated with vertically set enter running channel 4, the main running channel entered between running channel 4 and branch's running channel 3
Also connection sets adjusting rod positioning hole 5 on 2, and regulation positioning hole 5 is vertically installed in the downside of main running channel 2, in adjusting rod positioning hole 5
Slip is provided with adjusting rod 6, and the width of adjusting rod 6 is identical with the width of main running channel 2, and adjusting rod 6 is backwards to one end of main running channel 2
It is connected by connector 7 with the piston rod on cylinder 8, piston rod is also set along the length direction of adjusting rod positioning hole 5, cylinder
Tracheae connector 11 is provided with 8 tracheae 10, tracheae connector 11 is correspondingly arranged on solenoid directional control valve 12, solenoid directional control valve 12
Socket 14 is connected with by signal wire 13, socket 14 is connected with injection machine signal neutron.
When needing to adjust the flow of some cast gate, injection machine neutron changes to a signal to the electromagnetism of the governor motion
To the signal of valve 12, magnetic valve reversal valve 12 controls the distance that the advance of cylinder 8 or retrogressing are moved back, so as to realize plastics in mold runner
The uninterrupted or order of stream, a cast gate can be individually controlled to adjust, multiple cast gates can also be adjusted simultaneously.
