Description

Technical Field

[0001] This utility model relates to the field of aluminum profile mold technology, and in particular to a modular loading and unloading extrusion mold for aluminum profiles. Background Technology

[0002] A mold is a tool used to manufacture products of a specific shape. It is usually made of metal, plastic or other materials. It is used to process raw materials (such as plastic, metal, rubber, etc.) to form, punch, press or cut parts or products into specified shapes. Aluminum profile molds are molds specifically used to produce aluminum profiles (such as aluminum profile frames, aluminum alloy doors and windows, aluminum profile radiators, etc.). These molds are usually used to extrude aluminum alloy materials, extruding the aluminum material into specific profiles through the shape of the mold.

[0003] Because aluminum profile production lines need to produce various shapes of aluminum profiles, frequent mold changes are required. However, current aluminum profile mold replacement processes are cumbersome, resulting in long downtimes and impacting production efficiency. Traditional mold cleaning methods may not effectively prevent aluminum dross accumulation, affecting mold lifespan and production stability. Furthermore, mold designs do not consider the effects of excessively high impact pressure and flow resistance during aluminum extrusion, easily leading to surface defects or dimensional inaccuracies in the aluminum profiles. Therefore, this invention proposes a modular loading and unloading extrusion mold for aluminum profiles to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular extrusion die for aluminum profiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular extrusion die for aluminum profiles includes an inner die and an outer die. The inner die and the outer die together form an aluminum profile extrusion die. Heated aluminum alloy enters the extrusion die through one side of the outer die. Through the gap between the outer die and the inner die, an aluminum profile of a specific shape is formed. The inner die and the outer die are provided with quick-release positioning pin grooves on both sides of the inner die and the outer die. The quick-release positioning pin grooves correspond to the quick-release positioning pins of the extrusion die mounting structure. The inner die and the outer die are provided with several stepped working grooves on the left and right sides. The depth of the stepped working grooves is different. The inlet end of the outer die is provided with a flow guide fan-shaped opening. The outer die is provided with symmetrical diversion openings evenly on both sides. The symmetrical diversion openings are misaligned with the quick-release positioning pin grooves.

[0007] Preferably, both the inner mold and the outer mold are provided with self-cleaning V-shaped guide grooves, and the inner mold and the outer mold are provided with corresponding annular cleaning channels, with the angle of the self-cleaning V-shaped guide grooves being greater than °.

[0008] Preferably, the stepped working grooves are staggered and stepped, and the aluminum profile extrusion press mounting groove is provided with several limiting protrusions corresponding to the stepped working grooves.

[0009] Preferably, the guide fan-shaped opening area is provided with threaded holes, which are used to assist in the adjustment of the guide plate.

[0010] Preferably, the inner mold is provided with an inlet hole with a corresponding symmetrical diversion opening, the inner diameter of the inlet hole gradually decreases from the outside to the inside, and the inside of the inlet hole changes in a stepped manner.

[0011] Preferably, both the inner mold and the outer mold have modular quick-release slots on their outer upper sides, and the aluminum profile extrusion press mounting structure has quick-release positioning pins corresponding to the modular quick-release slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The present invention is designed to improve the efficiency of mold replacement and reduce downtime. The modular quick-release positioning pin slot and card slot design makes mold installation and disassembly convenient and quick to complete replacement, reducing downtime caused by maintenance during production. The automated cleaning system achieves 360° cleaning without dead angles through high-pressure air or cleaning agent, avoiding aluminum slag accumulation and further reducing cleaning time.

[0014] 2.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A modular extrusion die for aluminum profiles includes an inner die 1 and an outer die 2. The inner die 1 and the outer die 2 form an aluminum profile extrusion die. Heated aluminum alloy enters the extrusion die through one side of the outer die 2. Through the gap between the outer die 2 and the inner die 1, an aluminum profile of a specific shape is formed. Both the inner die 1 and the outer die 2 are provided with self-cleaning V-shaped guide grooves 8, and corresponding annular cleaning channels are provided inside the inner die 1 and the outer die 2. The angle of the self-cleaning V-shaped guide groove 8 is greater than 60°, ensuring that centripetal force is generated when the aluminum material flows, and throwing residual aluminum shavings along the groove wall to the annular cleaning channel. The ends of the guide grooves of the inner and outer dies 2 are connected to the annular channel to form a closed loop. When the machine stops, high-pressure air or cleaning agent can be injected to achieve 360° cleaning without dead angles, reduce manual cleaning time, and avoid dimensional deviations caused by aluminum slag accumulation. The self-cleaning V-shaped guide groove 8 is reserved with a quick-connect interface, which is compatible with automated cleaning equipment.

[0021] Both the inner mold 1 and the outer mold 2 are equipped with quick-release positioning pin grooves 3 on their internal alignment sides. The quick-release positioning pin grooves 3 correspond to the quick-release positioning pins of the extrusion die installation structure. The upper external sides of both the inner mold 1 and the outer mold 2 are provided with modular quick-release slots 5. The aluminum profile extrusion die installation structure is equipped with quick-release positioning pins corresponding to the modular quick-release slots 5. The pin shaft is equipped with a spring locking mechanism, which can be locked / released by manually rotating 90°. The modular quick-release slots 5 are rectangular with chamfered edges to prevent stress concentration during installation.

[0022] Both the inner mold 1 and the outer mold 2 have several stepped working grooves 4 on their left and right sides. The grooves 4 have different depths and are staggered. The aluminum profile extrusion press installation slot has several limiting protrusions corresponding to the stepped working grooves 4. The working grooves are divided into multiple levels, with adjacent grooves staggered by 5mm to form a discontinuous support structure. The protrusions in the extrusion press installation slot are fitted with the deepest groove. The forming pressure of the aluminum material is controlled by adjusting the number of protrusions. The staggered step design can adapt to different mold shapes, facilitate quick disassembly and replacement, reduce downtime, and make the mold components easy to maintain and replace.

[0023] The outer mold 2 has a flow guide fan-shaped opening 6 at the inlet end. The opening area of ​​the flow guide fan-shaped opening 6 has a threaded hole reserved. The flow guide plate is adjusted by the reserved threaded hole. The outer mold 2 has symmetrical flow splitting openings 7 evenly arranged on both sides. The symmetrical flow splitting openings 7 are misaligned with the quick-release positioning pin groove 3. The inner mold 1 has an inlet hole corresponding to the symmetrical flow splitting opening 7. The inner diameter of the inlet hole gradually decreases from the outside to the inside, and the inside of the inlet hole is stepped. The flow guide fan-shaped opening 6 reduces the impact pressure of the aluminum material. The symmetrical flow splitting opening of the inlet hole is stepped and the hole wall is polished to reduce flow resistance. The flow guide opening improves the uniformity of the initial flow velocity of the aluminum material and reduces the end face cracks of the extruded profile.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
