Abstract
The utility model discloses a mold head of a rubber extruder. The mold head includes a mold head body, a bin, and an extrusion hole with a length above 50 mm. Compared with the prior art, the mold head has the advantages of lengthened length of the extrusion hole, long extrusion hole channel where rubber passes is increased, prolonged cooling time, lower temperature of a rubber blank, less and relatively stable volume expansion, thereby ensuring accurate and stable size and weight of the extruded rubber blank, and meeting the requirement for medical plug production by vulcanizing the rubber blank.
Description
Technical field
The utility model relates to a kind of Rubber Extruder, relates in particular to a kind of die head of Rubber Extruder.
Background technology
The medical rubber plug manufacture method generally adopts the mode of rubber stock sulfidization molding, in order to guarantee not produce the rubber slitter edge in the rubber stock sulfidization molding or reduce the rubber slitter edge, just must guarantee that rubber stock weight and appearance and size before the sulfidization molding are precise and stable, and be complementary with the die cavity of curing forming mold.
The rubber stock can adopt Rubber Extruder extrusion modling mode.Please refer to Fig. 1, being depicted as existing Rubber Extruder die head illustrates, as shown in Figure 1, existing Rubber Extruder die head comprises die head body 2, feed bin 1, extrusion 3, extrusion 3 is shorter, generally in 50mm, and extrusion 3 does not have cooling device, extrusion 3 passages that rubber passes through during material extrusion are very short, cool time is very short, and the temperature of extrusion 3 can raise after die head worked long hours, at this moment the rubber stock Yin Wendu that extrudes is higher and expand, and the volume of the rubber stock of extruding will be far longer than the volume of rubber stock under the normal temperature, and volume plays pendulum, cause accurately to control the appearance and size and the weight of rubber stock, be difficult to the needs that the fulfilling medicinal plug is produced.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned prior art deficiency, and a kind of improved Rubber Extruder die head is provided.
The purpose of this utility model realizes by following technical solution:
A kind of Rubber Extruder die head comprises die head body, feed bin, extrusion, and described extrusion length is 50mm to 150mm.
The purpose of this utility model can also further realize by following technical solution:
Aforesaid Rubber Extruder die head, described extrusion can be provided with cooling device;
Aforesaid Rubber Extruder die head, described cooling device can be for being looped around the cooling water pipe of described extrusion sidewall;
Aforesaid Rubber Extruder die head, described cooling device can be for being looped around the air cooling equipment of described extrusion sidewall;
The beneficial effect that the utility model compared with prior art has is: the utility model extrusion length that extended, and the extrusion passage that rubber passes through during material extrusion is elongated, and prolong cool time, and the temperature of rubber stock is lower, and volumetric expansion is little and relatively stable; Simultaneously cooling device is set at extrusion, the temperature stabilization of the back extrusion that further guaranteed to work long hours, guarantee the rubber embryo appearance and size extruded and weight accurately, stable, thereby satisfy the needs that rubber stock sulfidization molding is produced medical rubber plug.
Description of drawings:
Fig. 1 is existing Rubber Extruder die head schematic diagram;
Fig. 2 is the utility model example structure schematic diagram;
Fig. 3 is another example structure schematic diagram of the utility model.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Embodiment 1: as shown in Figure 2, a kind of Rubber Extruder die head comprises die head body 2, feed bin 1, extrusion 3, and extrusion 3 length can be according to the prescription of rubber and the difference of temperature characterisitic, be chosen as 100mm, 120mm or 150mm, general extrusion 3 length are greater than 100mm.
Embodiment 2: as shown in Figure 3, a kind of Rubber Extruder die head, comprise die head body 2, feed bin 1, extrusion 3, cooling water pipe 4, extrusion 3 length can be according to the prescription of rubber and the difference of temperature characterisitic, be chosen as 50mm, 80mm or 100mm, general extrusion 3 length are 50mm to 100mm, and cooling water pipe 4 is looped around extrusion 3 sidewalls.
Embodiment 3: as shown in Figure 3, its difference from Example 2 is: air cooling equipment 4 is looped around extrusion 3 sidewalls.
Embodiment 4: as shown in Figure 3, its difference from Example 2 is: cooling water pipe 4 and air cooling equipment 4 are looped around extrusion 3 sidewalls simultaneously.。
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
