Abstract
The utility model relates to a kind of rubber for tire parts extruder die model, be specifically related to one and wait expansion extruder die model, comprise shape of the mouth as one speaks upper plate and shape of the mouth as one speaks lower plate, described shape of the mouth as one speaks upper and lower plates is fixedly connected with by screw, described shape of the mouth as one speaks upper plate is provided with lip, and the described shape of the mouth as one speaks upper plate side corresponding to lip arranges inclined-plane.The utility model structure is simple, and processing method is simple, practical, convenient; The utility model shape of the mouth as one speaks upper plate is provided with the inclined-plane regulating expansion rate, and under the direction on inclined-plane and the regulating action at inclination angle, the expansion that waits realizing rubber components is extruded; The rubber components porosity using the utility model to extrude is low, pore even, even density.
Description
Technical field
The utility model relates to a kind of rubber for tire parts extruder die model, is specifically related to one and waits expansion extruder die model.
Background technology
Shape of the mouth as one speaks model is that rubber industry extrudes the indispensable a kind of machine equipment of parts.Sizing material under the promotion energetically of extruder inner screw as powerful and well-equipped army crosses single-plank bridge by shape of the mouth as one speaks model, on volume, mainly on thickness, just have a certain amount of resilience by shape of the mouth as one speaks model once sizing material, namely expand.Expansion rate is the ratio of the open height extruding relevant position on each part thickness size of parts and shape of the mouth as one speaks model.The expansion rate at each position of parts has larger difference, and the position expansion rate that sizing material is pressed more real is larger, otherwise then less.Be exactly specifically that the position that parts are thinner is pressed more real, and expansion rate is larger, pore is more little fewer; The position that parts are thicker is pressed more empty, and expansion rate is less, and pore is more large more.Which results in and extrude parts each position expansion rate difference, density variation is comparatively large, and gas cell distribution is uneven, not of uniform size, as shown in Figure 2, thus greatly affects the combination property of sizing material.
Summary of the invention
The technical problems to be solved in the utility model is that to extrude parts each position expansion rate different, and density variation is comparatively large, and gas cell distribution is uneven, not of uniform size, provides expansion extruder die models such as extruding the whole parts porosity is low, pore is homogeneous, density is homogeneous one.
For achieving the above object, the utility model adopts following technical scheme:
One waits expansion extruder die model, and comprise shape of the mouth as one speaks upper plate and shape of the mouth as one speaks lower plate, described shape of the mouth as one speaks upper and lower plates is fixedly connected with by screw, and described shape of the mouth as one speaks upper plate is provided with lip, and the described shape of the mouth as one speaks upper plate side corresponding to lip arranges inclined-plane.
Angle between described inclined-plane and shape of the mouth as one speaks upper plate back side panel is 0-90 °.
The utility model structure is simple, and processing method is simple, practical, convenient; The utility model shape of the mouth as one speaks upper plate is provided with the inclined-plane regulating expansion rate, and under the direction on inclined-plane and the regulating action at inclination angle, the expansion that waits realizing rubber components is extruded; The rubber components porosity using the utility model to extrude is low, pore even, even density.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the rubber components section that prior art is extruded.
Fig. 3 is the rubber components section that the utility model is extruded.
Wherein 1. shape of the mouth as one speaks upper plates, 2. shape of the mouth as one speaks lower plate, 3. lip, 4. inclined-plane.
Detailed description of the invention
As shown in Figure 1, the utility model comprises shape of the mouth as one speaks upper plate 1 and shape of the mouth as one speaks lower plate 2, and described shape of the mouth as one speaks upper and lower plates is fixedly connected with by screw, and described shape of the mouth as one speaks upper plate is provided with lip 3, and the described shape of the mouth as one speaks upper plate side corresponding to lip arranges inclined-plane 4.Angle between described inclined-plane and shape of the mouth as one speaks upper plate back side panel is 0-90 °.
Position expansion rate on the corresponding rubber components in the position that shape of the mouth as one speaks model is thicker is less, position expansion rate on the corresponding rubber components in the position that shape of the mouth as one speaks model is thinner is larger, an equalization point always can be reached like this under the different acting in conjunction different with model thickness of component thickness, the each position of rubber components can be realized at this equalization point to extrude with identical expansion rate, thus realize that the whole parts porosity is low, pore is homogeneous, density is homogeneous, parts combination property is improved significantly, as shown in Figure 3.This equalization point needs to be realized by bevel direction and inclination angle of inclined plane, the angle between the inclined-plane of inclination angle of inclined plane and shape of the mouth as one speaks upper plate and bottom surface, and bevel direction is that bottom rubber components, corresponding model position is thicker, and corresponding model position, rubber components top is thinner.As for tilt angles, because various properties of rubber is different, rubber components difference in thickness difference should select different values.
Claims (2)
1. one kind is waited expansion extruder die model, comprise shape of the mouth as one speaks upper plate (1) and shape of the mouth as one speaks lower plate (2), described shape of the mouth as one speaks upper and lower plates is fixedly connected with by screw, it is characterized in that: described shape of the mouth as one speaks upper plate (1) is provided with lip (3), and shape of the mouth as one speaks upper plate (1) side corresponding to lip arranges inclined-plane (4).
2. model such as extruder die such as expansion such as grade according to claim 1, is characterized in that: the angle between described inclined-plane and shape of the mouth as one speaks upper plate back side panel is 0-90 °.
