Abstract
The utility model relates to a material mould inside an extruder. The material mould comprises a material mould body, wherein installation flanges are arranged outside the material mould body; a material hole is formed in the center part of the material mould body and is in a trumpet shape, the aperture of the material hole is gradually reduced along with the flowing direction of a material, and the wall of the material hole is provided with a smoothly transitional cambered surface. The material mould inside the extruder, which is disclosed by the utility model, is slightly improved on the basis of a material mould used at present by changing the wall of the material hole into the smoothly transitional cambered surface, and thus even a thick material can be easily extruded when the material passes through the material hole.
Description
Technical field
The utility model relates to the material mould field in extruder, refers to especially the material mould in a kind of extruder.
Background technology
Extruder is in when work, and first material is heated to semi-molten state, and then material, externally under the effect of pressure, falls the impurity such as iron filings in material by strainer filtering, then by flow distribution plate, realizes shunting, finally enters and expects that mould realization extrudes.The material mould using at present comprises material mould body, and the outer setting of material mould body has mounting flange, and the middle part of material mould body is provided with material hole, and material hole is bellmouth, and the aperture in material hole dwindles gradually with the flow direction of material.The shortcoming of above-mentioned material mould is: because material is semi-molten state, externally under the effect of pressure, could pass through the material hole in material mould, then realize and extruding, material is after entering plup inlet, because material hole is bellmouth, its hole wall is the inclined-plane of a linearity, and when material is the material of comparatively thickness, material can more difficultly be extruded.
Utility model content
Technical problem to be solved in the utility model is: a kind of material mould that can make in extruder that material is easily extruded is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the material mould in extruder, comprise material mould body, the outer setting of material mould body has mounting flange, the middle part of material mould body is provided with material hole, material hole is flared hole, and the aperture in material hole dwindles gradually with the flow direction of material, and the hole wall in described material hole is smooth excessive cambered surface.
The beneficial effects of the utility model are: the material mould in above-mentioned extruder, it improves a little on current used material mould, changes the hole wall in material hole into smooth excessive cambered surface, and material is when logical material path, even comparatively the material of thickness, also can be extruded easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional structure schematic diagram of A-A direction in Fig. 1;
In figure: 1, material mould body, 2, mounting flange, 3, material hole, 4, cambered surface.
The specific embodiment
Below by specific embodiment, the material mould in extruder described in the utility model is described in further detail.
As shown in Figure 1 and Figure 2, material mould in extruder, comprise material mould body 1, the outer setting of material mould body 1 has mounting flange 2, the middle part of material mould body 1 is provided with material hole 3, material hole 3 is flared hole, and the aperture in material hole 3 dwindles gradually with the flow direction of material, and the hole wall in described material hole 3 is smooth excessive cambered surface 4.
Material mould in above-mentioned extruder, it improves a little on current used material mould, changes the hole wall in material hole 3 into smooth excessive cambered surface 4, and material is when logical material path 3, even the material of thickness comparatively also can be extruded easily.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (1)
1. the material mould in extruder, comprise material mould body, the outer setting of material mould body has mounting flange, the middle part of material mould body is provided with material hole, material hole is flared hole, the aperture in material hole dwindles gradually with the flow direction of material, it is characterized in that: the hole wall in described material hole is smooth excessive cambered surface.
