Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of be based on the molding automobile lamp lens die of three template die secondary extrusions, it successively include moving template
1, solid plate 2 and injection molding plates 3, forming cavity 4 is between moving template 1 and solid plate 2, wherein is connected in moving template 1 dynamic
Mould mode 11 is connected with cover half mode 21 in solid plate 2, and dynamic model mode 11 and cover half mode 21 are enclosed forming cavity 4,
Injection molding plates 3 are equipped with injection hole 31, and injection hole 31 is connected by injection molding channel 5 with forming cavity 4, and the moving template 1 is far from fixed
The side of template 2 is additionally provided with secondary extrusion mechanism 6, and the secondary extrusion mechanism 6 is connected by elastic mechanism 7 and 1 elasticity of moving template
It connects, and one end of secondary extrusion mechanism 6 extends in forming cavity 4, also has between the secondary extrusion mechanism 6 and moving template 1
Top clearance 8.
The utility model, in use, moving template 1 and solid plate 2 are bonded to each other, to make dynamic model mode 11 and cover half mode
21 are bonded to each other and are enclosed forming cavity 4, and the melt plastic cement in injection molding machine is injected by injection hole 31 via injection molding channel 5
In shape chamber 4, after the completion of injection molding, secondary extrusion mechanism 6 completes secondary extrusion close to moving template 1 under the effect of external force, squeezes at this time
Gap 8 is pressed to disappear, therefore the utility model is based on three template dies molded lens product in such a way that secondary extrusion is molding, can be applicable in more
The lens products of different structure shape, and greatly reduce dwell time and dwell pressure, reduce the loss to mold, from
And reduce production cost.
Preferably, maximum width of the forming cavity 4 on die sinking direction is 25.5mm, and the top clearance 8 is
0.5mm, the forming cavity 4 for being 25.5mm for maximum gauge set top clearance 8 to after 0.5mm can guarantee extruding, and injection molding produces
The cubical contraction of product is in OK range.
As shown in Figure 1, the secondary extrusion mechanism 6 includes opening baffle 61,7 one end of elastic mechanism is pressed on out baffle 61
On, the other end is pressed on moving template 1, the extruding force block 62 that prominent oriented 1 direction of moving template in 61 surface of baffle extends is opened,
It further include that one end is connected on extruding force block 62, the other end extends to the secondary extrusion bar 63 in forming cavity 4, described secondary
Pressure ram 63 is slidably connected with moving template 1, and top clearance 8, which is located at, to be squeezed between force block 62 and moving template 1, the secondary extrusion
Bar 63 includes the bar body 64 that is detachably connected and crushing block 65, bar body 64 far from one end of crushing block 65 be connected to extruding by
On power block 62, the crushing block 65 is located in forming cavity 4, and the crushing block 65 is tightly connected with 4 side of forming cavity, can prevent in this way
Only melt plastic cement is leaked out from 65 side of crushing block in forming cavity 4, and can not achieve the molding purpose of secondary extrusion.
Starting secondary extrusion is that external force is opening 61 bottom surface of baffle, and elastic mechanism 7 is further compressed at this time, so that
With open the integrally formed extruding force block 62 of baffle 61 to moving template 1 at a distance from a top clearance 8, bar body 64 and squeeze
Briquetting 65 squeeze force block 62 promotion under the melt plastic cement in forming cavity 4 is compressed, thus complete secondary extrusion at
Type.
Preferably, ejecting mechanism is pressed on out on baffle 61, and the sliding close to or far from moving template 1 can occur, with complete
At the ejection of injecting products, be equivalent in this way will open baffle 61, mold support block and die bottom plate be designed to one it is unified whole
Body, the thickness for opening baffle 61 in this way can increase to 100mm, greatly reinforce the intensity for opening baffle 61, prevent it in secondary extrusion mistake
Deformation occurs in journey, and compared to the overall thickness opened baffle 61, mold support block and die bottom plate about 180mm is respectively set, one
Body setting opens baffle 61 with smaller thickness, can better meet the molar thickness of injection molding machine.
Preferably, the crushing block 65 is recessed inwardly arc-shaped far from the end surface of bar body 64, is squeezing in this way
Cheng Zhong, melt plastic cement surface receive one be directed toward melt plastic cement inside resultant force, so in extrusion process melt plastic cement by
Be one contraction power, reduce melt plastic cement overflow possibility, improve extruding efficiency.
As shown in Figure 1, the elastic mechanism 7 includes Top fastening screw 71 and the disc spring 72 being set in Top fastening screw 71, institute
It states 71 one end of Top fastening screw to be embedded in secondary extrusion mechanism 6, the other end penetrates through disc spring 72 and is pressed on moving template 1, institute
It states 72 one end of disc spring to be pressed in secondary extrusion mechanism 6, the other end is pressed in Top fastening screw 71.
It selects helical spring always there are gradual change power, cannot allow the 0.5mm dimensionally stable of top clearance 8, if used
Mechanism, which is blocked, generates gap, and because clamp force generates always, locking force of injection machine, which can block mechanism, cannot be slided thus cannot be real
Existing secondary extrusion molding, therefore disc spring 72 has been selected in elastic mechanism 7.
Disc spring 72 is special spring that is tapered in the axial direction and bearing load, and after bearing load deformation, savings are certain
Potential energy, when bolt relaxes, disc spring 72 discharge part potential energy to keep the pressure between flanged joint to reach seal request.
72 stress distribution of disc spring is uniformly successively decreased from inside to outside, can be realized the effect of the high balancing force of low row journey.
Disc spring 72 is in compressive state always, and the injection pressure in injection moulding process is about 17.75MPa, and disc spring 72 is logical at this time
It crosses Top fastening screw 71 and the pressure for being greater than the injection pressure is applied to moving template 1, in this way while keeping top clearance 8
It can prevent injecting products from generating burr, when secondary extrusion, under external force, disc spring 72 is further compressed, so that two
Secondary pressing mechanism 6, close to the distance of a top clearance 8, is formed to moving template 1 with completing secondary extrusion.
It referring to figs. 1 and 2, further include the heating mantle 9 for being located in solid plate 2 and being set in 5 outer surface of injection molding channel,
The heating mantle 9 is electrically connected with the electrical outlet 10 that 2 side of solid plate is arranged in, and electrical outlet 10 is connect with external power supply, so that plus
The problem of 9 heating power of hot jacket, prevents melt plastic cement from condensing in injection molding channel 5, blocks runner occurs.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although be used more herein moving template 1, solid plate 2, injection molding plates 3, forming cavity 4, injection molding channel 5, it is secondary squeeze
Press mechanism 6, elastic mechanism 7, top clearance 8, heating mantle 9, electrical outlet 10, dynamic model mode 11, cover half mode 21, injection hole 31,
It opens baffle 61, squeeze the arts such as force block 62, secondary extrusion bar 63, bar body 64, crushing block 65, Top fastening screw 71, disc spring 72
Language, but it does not exclude the possibility of using other terms.The use of these items is only for be more convenient to describe and explain this
The essence of utility model；It is contrary to the spirit of the present invention to interpret them as any one of the additional limitations.
