Identical structure and symmetrical setting.Extrusion efficiency is effectively promoted in one mold for going out two structures, and extrusion efficiency can
Reach 1.8 times that original one goes out an extrusion process method, reduces product processing cost, more preferably improve the competitiveness of product.
Die head as seen in figs. 5-6, including machine neck 31, mouth mold 36, adjusts bolt 33, spreader 32 and mold core 37, machine neck 31
Up and down with mouth mold 36, machine neck 31 and mouth mold 36 are assembled together to form die cavity by bracket 34, spreader 32 and mold core
37 are fixedly arranged in die cavity, and specifically, the inner surface of 31 lower part of machine neck has hierarchic structure, and the outer surface on 36 top of mouth mold has method
Blue structure, the middle part of spreader 32 have a flanged structure, and mold core 37 is removably installed in point by bolt 38 and fixation hole 322
It at the bottom of flow cone 32, adjusts 33 drawing-in machine neck 31 of bolt and is abutted with the flange arrangement of mouth mold 36, bracket 34 and machine neck 31 are logical
Cross the connection of bolt 35, and mouth mold 36 and spreader 32 be secured in a press along its axis direction, the flanged structure of spreader 32 with
It fits closely and is positioned between the hierarchic structure of machine neck 31, and then be kept fixed the position of mold core 37, the ladder of machine neck 31
There are gap, multiple peripheries for adjusting bolt 33 and being evenly arranged on the flange arrangement of mouth mold 36 between structure and the flange arrangement of mold core 37
And abutted with it, by adjusting the precession of bolt 33, screw out, can position to mouth mold 36 carried out along its vertical axis direction
Adjustment, can be adjusted the spacing between mouth mold 36 and mold core 37, is adjusted so as to the structure to product.The structure mentions significantly
The adjustability of product processing is risen, structure is more flexible reliable, the number that repairs a die can be reduced, so as to shorten development cycle, drop
Low molding cost when producing different types of product, only needs to change mold core 37, and other components can share, and suitability is more
It is good, can application range it is bigger.For example, only needing replacing mold core, the present embodiment when the tubing LED lamp tube of production different structure
Mold especially suitable for producing all kinds of circular LED lamp tubes.
It should be understood that uniformly distributed at the flange mechanism of spreader 32 have stream chamber 321, for by the modeling of molten state
Material is evenly directed to mold core 37.
It should be noted that in order to keep moulding compound performance stabilization, the stabilization of extrusion die temperature, every part of die head is excellent
Choosing is equipped with controllable heater and carries out heated for controlling temperature.
When producing the overall plastic lampshade of LED, melt flows into die head, by the current stabilization of machine neck 31, the shunting of spreader 32, mouth mold 36
After the molding three phases of mold core 37, from die head extrusion plastic parison, after air gap, entered to be formed on sink by traction
Stock mould carry out shaping and cool down, eventually become plastic product.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
