Description

A hollow and solid profile extrusion die

technical field

The utility model belongs to the technical field of profile processing dies, in particular to a hollow and solid profile extrusion die.

Background technique

Traditional profiles can be divided into solid and hollow. The traditional technology uses two kinds of molds for solid and hollow respectively. The mold structure is complex, the cost is high, and the manufacturing process is inconvenient to switch. It is necessary to change the production mode by changing the mold, which greatly reduces the production efficiency.

Utility model content

The technical problem to be solved by the utility model is to provide a hollow and solid profile extrusion die which can fuse multiple materials and produce solid and hollow profiles at the same time, greatly improving production efficiency.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a hollow and solid profile extrusion die, including forming plates and co-extruded plates stacked in sequence, the forming plate is the forming area of the profile, and the forming plate is set There is a cavity suitable for the shape of the profile. The cavity includes the main body forming area of the profile body and the co-extrusion layer area. A detachably connected inner core which forms the hollow part of the profile.

It also includes a split body, the split body is provided with a profile main body flow channel communicating with the main body forming area of the forming plate, and the profile main body flow channel corresponds to the main body area of the profile.

A transition plate, a support plate and a compression plate are sequentially provided between the split fluid and the co-extrusion plate, and flow channels are all provided on the transition plate, the support plate and the compression plate.

The end of the split fluid is provided with a machine neck for the material to enter.

The co-extruded layer is a wear-resistant layer or an anti-aging layer.

One of the above-mentioned technical solutions has the following advantages or beneficial effects. It can integrate multiple materials, and a mold can produce solid and hollow profiles at the same time. It only needs to disassemble the inner core, which greatly improves production efficiency.

The marks in the above figures are: 1. Neck, 2. Distributor, 3. Transition plate, 4. Support plate, 5. Compression plate, 6. Co-extrusion plate, 7. Forming plate, 8. Inner core.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, a kind of hollow and solid profile extruding die, comprise forming plate (7) and coextrusion plate (6) stacked successively, forming plate (7) is the forming area of profile, forming plate (7) is provided with A cavity that matches the shape of the profile. The cavity includes the main body forming area of the profile body and the co-extrusion layer area. The co-extrusion plate (6) is provided with a rubber strip flow channel that communicates with the co-extrusion layer area; it also includes the main body forming area. A detachably connected inner core (8) constituting the hollow part of the profile.

It also includes a sub-body (2). The sub-fluid (2) is provided with a profile main body flow channel communicating with the main body forming area of the forming plate (7), and the profile main body flow channel corresponds to the main body area of the profile.

A transition plate (3), a support plate (4) and a compression plate (5) are sequentially arranged between the split body (2) and the co-extrusion plate (6), and the transition plate (3), the support plate (4) and the compression plate (5 ) are equipped with runners.

The end of the splitter (2) is provided with a machine neck (1) for the material to enter.

The co-extruded layer is a wear-resistant layer or an anti-aging layer. The co-extrusion layer can choose other materials according to the needs, so as to achieve the purpose of producing a mold with multiple materials.

After the above-mentioned structure is adopted, various materials can be fused, and a single mold can simultaneously produce solid and hollow profiles, and only the inner core (8) needs to be disassembled, thereby greatly improving production efficiency.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the utility model, or Directly applying the ideas and technical solutions of the utility model to other occasions without improvement is within the protection scope of the utility model.
