Description
Technical field
The utility model relates to technical field of mold, specially a kind of steel molding die of variable cross-section super thick BMC product.
Background technique
Fiber reinforced thermosetting resin (FRP) is formed after being mixed according to a certain percentage by fibrous material with basis material
High-performance profile material has light and hard, non-conductive, high mechanical strength, recycles few, the characteristics such as corrosion-resistant, this material
During compression molding, due to the poor fluidity of BMC (tubular molding compound), it is not easy to suppress and, die sinking is complicated, traditional mould
The spue line of tool usually when middle position (Fig. 2), BMC (tubular molding compound) are under pressure load in forming process, is easy
It splits from spue line, is not able to satisfy requirement.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, provides a kind of variable cross-section super thick BMC product
Steel molding die, this mold by the position of spue line by forming cavity middle part (Fig. 2) modification to forming cavity top (figure
1) high-intensitive BMC material poor fluidity, is solved, it is difficult to the problem of forming, and plastics to be formed will not under external pressure
Split from spue line, thoroughly solve variable cross-section super thick fiber reinforced thermosetting resin BMC (tubular molding compound) product at
Type and strength problem can effectively solve the problems in background technique.
To achieve the above object, the utility model provides the following technical solutions: a kind of steel of variable cross-section super thick BMC product
Molding compression mould, including lower mold body and upper die body, the cavity that the upper die body lid is formed after being located in lower mold body are forming cavity, on
The contact position of die body and lower mold body is spue line, and the spue line is located at the upper end of forming cavity.
As a kind of optimal technical scheme of the utility model, the cross section of the forming cavity is in " H " shape.
As a kind of optimal technical scheme of the utility model, the lower mold body and upper die body are made of stainless steel material.
Compared with prior art, the utility model has the beneficial effects that the steel die pressing mold of this variable cross-section super thick BMC product
The position of spue line is modified by the middle part (Fig. 2) of forming cavity to the top (Fig. 1) of forming cavity, solves high-intensitive BMC by tool
Material flowability is poor, it is difficult to the problem of forming, and plastics to be formed will not split under external pressure at spue line, thoroughly
Solve the molding and strength problem of variable cross-section super thick fiber reinforced thermosetting resin BMC (tubular molding compound) product.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is this traditional moulds spue line positional structure schematic diagram.
In figure: 1 lower mold body, 2 upper die bodies, 3 spue lines, 4 forming cavities.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of steel die of variable cross-section super thick BMC product
Compression mould, including lower mold body 1 and upper die body 2, lower mold body 1 and upper die body 2 are made of stainless steel material, and the lid of upper die body 2 is located at down
The cavity formed after on die body 1 is forming cavity 4, and the cross section of forming cavity 4 is in " H " shape, the contact position of upper die body 2 and lower mold body 1
For spue line 3, spue line 3 is located at the upper end of forming cavity 4, and the position of spue line 3 is modified extremely by the middle part (Fig. 2) of forming cavity 4
The top (Fig. 1) of forming cavity 4, solves high-intensitive BMC material poor fluidity, it is difficult to the problem of forming, and plastics to be formed exist
It will not split from spue line under external pressure, thoroughly solve variable cross-section super thick fiber reinforced thermosetting resin BMC (bulk
Moulding compound) product molding and strength problem.
The steel molding die of this variable cross-section super thick BMC product is repaired the position of spue line by the middle part (Fig. 2) of forming cavity
It is changed to the top (Fig. 1) of forming cavity, solves high-intensitive BMC material poor fluidity, it is difficult to the problem of forming, and plastics to be formed
It will not split at spue line under external pressure, thoroughly solve variable cross-section super thick fiber reinforced thermosetting resin BMC (group
Shape moulding compound) product molding and strength problem.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
