Description

Extrusion die structure

The present invention relates to an extrusion mold, and more particularly to an innovative structural type revealer for an extrusion mold for extruding high viscosity materials.

According to the current automatic production method of producing noodles or winter powder, the dough is placed in an extrusion dough machine, and the dough is squeezed under the high pressure provided by the dough machine and at the front end of the dough machine. The mold is squeezed out to achieve the purpose of automatically making noodles. As shown in FIG. 1 , the conventional extrusion die includes a hollow pipe body 10 and has a feed port 11 and a discharge port 12, and is opened at the end of the discharge port 12 of the hollow pipe body 10. There is a serrated edge 13 for squeezing the noodles of a non-circular cross section. However, such a conventional extrusion mold type has found that the following problems still exist in the actual use experience: since the conventional extrusion mold is attached to the end surface of the discharge port 12 of the hollow pipe body 10, it is cut off by a cross section. A serrated structure, such that the structural design has a sharp or protruding edge 13 in its appearance, which is liable to stab the operator, and the sawtooth structure will cause the hollow tubular body 10 to fail to maintain good structural integrity, thereby affecting the conventional knowledge. The structural strength of the extrusion die; furthermore, since the dough in the hollow pipe body 10 has a high viscosity, it is necessary to use the high-pressure thrust provided by the dough machine to derive the noodles one by one, but the structural strength of the conventional extrusion die is insufficient. In the case of a long time and high pressure environment, it is very easy for the sawtooth structure to be deformed, cracked or even broken, and even the broken part or metal shavings may be squeezed into the noodles. There is also a jagged sharp structure that is also difficult to clean and causes significant food safety problems.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

Please refer to Figures 2, 3 and 4 for a preferred embodiment of the present extrusion die structure, but such embodiments are for illustrative purposes only and are not limited by this structure in the patent application. The extrusion die structure comprises a tapered tubular body 20, and the tapered tubular body 20 is used in conjunction with an extrusion device (not shown), and the extrusion device provides an extruded material (not shown). The pressure of the delivery conveys the extruded material into the tapered tubular body 20. The extruded material may be a high-viscosity substance such as a pasta food made of one or a combination of flour, buckwheat flour, rice flour, barley flour, and winter flour.

The tapered tubular body 20 is made of a metal material, and the tapered tubular body 20 defines a first tubular section 21 and a second tubular section 22 according to the position, and an outer surface of the second tubular section 22 is formed with an inlet opening 221, The outer end surface of a pipe section 21 forms a conical discharge hole 211, and the central axis of the conical pipe body 20 is located on the same axis as the center of the conical discharge hole 211. Further, five grooves 30 are formed in the outer surface of the first pipe segment 21 at a position opposite to the tapered discharge hole 211, and the grooves 30 are evenly distributed on the outer surface of the first pipe segment 21, so that the horizontal cross section of the tapered discharge hole 211 is A star structure. In other embodiments, the outer surface of the first pipe segment 21 may also be recessed to form at least three grooves 30 for changing the structural shape of the horizontal cross section of the tapered discharge hole 211. In this example, the angle between the extending direction of the groove bottom of the groove 30 and the extending direction of the outer surface of the first pipe section 21 is an acute angle θ. In addition, the width of the tapered tubular body 20 is gradually diverged from the tapered discharge hole 211 toward the inlet port 221, and a communicating inlet port 221 and a tapered discharge hole 211 are formed inside the tapered tubular body 20. The material channel 23 is provided.

In this example, the outer surface of the first pipe section 21 is formed with a convex arc portion 31 at the joint between any two grooves 30, and the inner wall surface of the first pipe segment 21 is further formed with a concave groove 32 with respect to the convex arc portion 31. Moreover, the horizontal cross-sectional shape of the tapered discharge hole 211 is interconnected through the grooves 30 and the convex arc portions 31 to define a continuous and complete slit structure. The root of each of the grooves 30 constitutes a small diameter section 212 of a tapered discharge hole 211, and the root of the concave channel 32 constitutes a large diameter section 213 of a tapered discharge hole 211, and the large and small diameters The difference in spacing between the segments 213, 212 is the groove depth of the trench 30.
