The utility model has the following beneficial effects: ventilative foaming mould provided by the utility model is by 3D printing technique system
At each part is integrally formed, and is reduced more splicing step, is improved production efficiency, saved cost of labor.In addition,
By the topological structure of the second air-permeable layer to realize the function of enhancing heat dissipation discharge vapor in mold injection molding, thus
Improve product quality.
Detailed description of the invention
Fig. 1 is the schematic perspective view of ventilative foaming mould provided by the utility model；
Fig. 2 is the three-dimensional cross section structure schematic diagram of ventilative foaming mould provided by the utility model；
Fig. 3 is the topological structure schematic diagram of the second air-permeable layer of ventilative foaming mould provided by the utility model.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to attached drawing, the utility model is further described.
As shown in Figure 1-Figure 3, ventilative foaming mould provided by the utility model, specific technical solution are as follows:
Ventilative foaming mould, including die body 1, die body 1 are made of 3D printing technique, and the recess of die body 1 is formed with type chamber 2, type
The bottom of chamber 2 successively includes the first air-permeable layer 21 and the second air-permeable layer 22 from the inside to the outside, and the first air-permeable layer 21 is fine and closely woven porous knot
Structure, the second air-permeable layer 22 are topological structure, and the aperture of the air hole in the first air-permeable layer 21 is 0.1-0.3 millimeters.Mold is whole
It is made of 3D printing technique, each part is integrally formed, and reduces extra splicing step.The porous structure of first air-permeable layer 21
With the design of the topological structure of the second air-permeable layer 22, the venting quality in injection moulding process is enhanced.
In some embodiments, the first air-permeable layer 21 with a thickness of 2-4 millimeters, die body 1 is compact texture.In this way,
In injection moulding process, injected plastics material does not outflow, and airtightness is good.
In some embodiments, mold is divided into two parts and is made of 3D printing technique, including first 3 and second 4,
First 3 and second 4 is welding splicing, and first 3 and second 4 carries out welding splicing, the area of welding by positioning tiger's jaw 5
Field width degree is less than 4 millimeters.Positioning is realized by positioning tiger's jaw 5, is welded less than 4 millimeters, to not influence the shape of shaped article
Flatness.
In the present embodiment, mold is made of male model 11 and master mold 12, air hole of first air-permeable layer 21 on male model 11
