Technical Field

[0001] The invention relates to the technical field of mould processing, in particular to a preheating and heat-insulating industrial aluminium profile extrusion barrel mould. Background Art

[0002] With the rapid advancement of my country's large-scale infrastructure investment and industrialization process, aluminum profiles, as important application materials in the construction field and mechanical industry, have seen rapid growth in production and consumption throughout the industry. my country has also become the world's largest aluminum profile production base and consumer market. After nearly a decade of rapid growth, my country's aluminum profile industry has entered a new stage of development and has shown many new development trends. With the national industrial policy, industrial structure adjustment and consumers' increasing requirements for product quality, the current situation of the aluminum processing industry, which is extensive and low in added value, has gradually changed. It has crossed the primary development stage characterized by quantitative growth and has entered a new stage of improving product intrinsic quality, enriching product categories, and relying on comprehensive strength to participate in market competition.

[0003] Aluminum products have a series of excellent properties, such as good strength, good weather resistance, low density, etc., and are widely used in construction and industry. Many existing tubular aluminum profiles are prepared by hot extrusion molding process, and its core component is the mold. The existing tubular aluminum profile extrusion mold generally includes a guide mold and a mold body. The guide mold and the mold body are fixedly connected. A feed channel is arranged in the center of the guide mold, and a guide bridge is fixed in the feed channel. A mold shaft is fixed on the guide bridge. A discharge channel corresponding to the mold shaft can form an extrusion molding port, and the tubular aluminum profile can be extruded through the extrusion molding port. However, in the prior art, the aluminum profile is often discharged from the discharge channel for a short time, and because the temperature is still very high when it is just discharged, it is very difficult to shape the tubular aluminum profile. Fine lines are often prone to appear on the surface of the tubular aluminum profile, and even bending may occur, which greatly affects the quality of the product. However, there are still certain problems when the existing aluminum profile extrusion barrel mold is used:

[0004] For example, a tubular aluminum profile extrusion die with publication number CN203917450U, its technical solution is: including a guide die and a die body, a feed channel is arranged in the center of the guide die, a guide bridge is fixedly arranged in the feed channel, a die shaft is fixedly arranged on the guide bridge, a discharge channel corresponding to the die shaft and constituting an extrusion molding port is arranged on the die body, a discharge die is fixedly connected to one end of the die body away from the guide die, a discharge channel which is connected to the discharge channel and has the same shape and size as the discharge channel is arranged on the discharge die, a through hole which can be filled with inert gas is arranged on the outer wall of the discharge die, and the through hole is connected to the discharge channel. The utility model has a reasonable and simple structure, can make the products produced better shaped and have high surface finish, and greatly improves the product quality, but the existing aluminum profile bobbin cannot guarantee the temperature of the mold during processing. If the ambient temperature is low, the molding of the extruded part will be accelerated, and extrusion will be more difficult, affecting the production efficiency of the aluminum profile.

[0005] In view of this, we conducted in-depth research on the above issues, which led to the present case.
