Description
Technical field
The utility model relates to technical field of mold, more particularly, to a kind of crack resistence spreader bracket of wood moulding mold.
Background technique
Wood moulding mold belongs to the modern designs of plastics, is mainly used to do wood moulding extrusion, extrusion die is mainly by head and stock mould two
It is grouped as.Head is the key component for forming plastic, its effect is that the molten plastic for squeezing out extruder is become by screw
It to move along a straight line, and is plasticized molten plastic further, generates necessary briquetting pressure, guarantee that plastic is closely knit, obtained by head
Plastic required for obtaining.Head includes mouth mold 1, plug 2, spreader 3 and spreader bracket 4, as depicted in figs. 1 and 2.Wherein,
Spreader is commonly called as torpedo head, and effect is to make to become thin ring-type by its plastic melt shunting to stably enter shaping area, together
When further heat and be plasticized.Spreader bracket is mainly used to support spreader and plug, while also can be to the plastics after shunting
Melt acts the interflow for reinforcing shearing, as shown in figure 3, but generate weld mark sometimes and influence plastic intensity, especially mould
When expecting material quality difference, the surface that the product extruded corresponds at spreader bracket is easy cracking.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, propose a kind of crack resistence spreader branch of wood moulding mold
Frame solves extruded product in the prior art and corresponds to the technical issues of being easy cracking at spreader bracket.
To reach above-mentioned technical purpose, the technical solution of the utility model provides a kind of crack resistence spreader of wood moulding mold
Bracket, the surface of the bracket include fluoran stream surface, lee side and the first side and second side that connect fluoran stream surface and lee side
Face, the first side include the first shear surface at first side ontology and at least one, and second side includes second side ontology
And the second shear surface at least one, first shearing are drawn close towards the second side ontology, second shearing is towards institute
It states first side ontology to draw close, first shear surface and the second shear surface are in pairs and dislocation is arranged, the lee side has pair
At least two answered.
Compared with prior art, the beneficial effects of the utility model include: spreader bracket drawing by multiple shear surfaces
It leads, collaborates plastic melt in the same position when passing through, that is, desalinated the interflow seam generated in existing way, plastic melts
Lapping defect is unobvious, and intensity is high, not easy to crack.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment 1 provides a kind of crack resistence spreader bracket of wood moulding mold, as shown in figure 4, the surface of the bracket
Including fluoran stream surface 41, lee side 44 and the first side 42 and second side 43 that connect fluoran stream surface 41 and lee side 44, described the
One side 42 includes the first shear surface 42b at first side ontology 42a and at least one, and second side 43 includes second side ontology
Second shear surface 43b, the first shear surface 42b is drawn close to the second side ontology 43a at 43a and at least one, and described
Two shear surface 43b are drawn close to the first side ontology 42a, and the first shear surface 42b and the second shear surface 43b are in pairs and wrong
Position arrangement, the lee side 44 have corresponding at least two.
When plastic melt passes through this spreader bracket, is realized and shunted by the fluoran stream surface 41 of spreader bracket, through first side
42 and second side 43 after realize and collaborate in lee side 44, and produced under the guidance of the first shear surface 42b and the second shear surface 43b
Raw different interflow position, extruded product will not generate apparent weld mark, and product strength is high, not easy to crack.
Preferably, the angle of the first shear surface 42b and the second shear surface 43b less than 45 °, are closed with realizing to separate
While flowing position, reduce resistance when plastic melt flows through.
Embodiment 2 provides a kind of crack resistence spreader bracket of wood moulding mold, on the basis of embodiment 1, described
One shear surface 42b and the second shear surface 43b is equipped with the guide piece 45 being arranged along plastic extruding direction, as shown in Figure 5.Guide piece 45 is convenient for
Plastic melt uniform divided flows overcome the problems, such as because imperfect flow occurs when the factors such as gravity cause plastic melt to shunt.
Embodiment 3 provides a kind of crack resistence spreader bracket of wood moulding mold, described on the basis of embodiment 1 or 2
Lee side 44 is serrated face, as shown in Figure 6.Serrated face facilitates the smooth interflow of plastic melt, reduces plastic melt adhesion point
Flow cone bracket also reduces extrusion molding resistance.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical
In novel scope of protection of the claims.
