Description
Technical field
The present invention relates to a kind of BMC injection (mo(u)lding) machines, are the technical fields for belonging to injection (mo(u)lding) machine.
Background technique
BMC is mainly by unsaturated poly-vinegar resin, the chopped auspicious fiber of glass, fleut, crosslinking agent, curing agent and release agent etc.
Bulk composed by ingredient or putty-like preforming material, BMC have very high mechanical strength, and good electrical insulating property resists
The performances such as static behaviour, tracking-resistant, chemical corrosion resistance, therefore it is widely used in the fields such as electrical, electronic engineering and building.
The density of BMC be about 1.3-2.1g/cm(this additionally depend on the grade of material), the handling property of product is fine, has hard
And the feeling that weight is thick, BMC moulding compound is exactly viscoelastic body at normal temperature, and relatively stable.When at a temperature below 60 DEG C, very
Reaction can be crosslinked less, but if curing reaction can occur rapidly more than 60 DEG C, BMC chess plastics have ratio at the time of molding
Traditional expects the better processing fluidities of thermosetting plasticses such as aldehyde, trimerization atmosphere amine, especially has good low pressure mobility, can use
Lower injection pressure, higher injection speed are injected, and obtain the high product of surface-brightening, dimensional accuracy.Ready-made
The method for processing forming of many thermosetting plasticses, such as compacting and are injected into denier at die casting (transfer molding), can be used in BMC mould
The processing and forming of plastics, in molding or injection moulding, resin, fiber, filler can flow simultaneously, and rapidly and evenly be full of mould
Under heating, pressurized conditions cross-linking reaction occurs for chamber, unsaturated poly-vinegar resin component related with other of BMC towel, is formed
Macromolecular network with labyrinth, in a few minutes, so that it may which it is once made at ware higher stiffness and strength, has
Deep muscle, pre-buried inserts or projective structure, the second best in quality complex parts.The BMC material that vinegar resin is substrate is obtained by unsaturation,
It does not have gas, moisture and molding volatile matter in forming and hardening process towel to generate, cured speed is also very fast.
Summary of the invention
Goal of the invention: to solve the above-mentioned problems, the present invention provides a kind of BMC injection (mo(u)lding) machine.
Summary of the invention: a kind of BMC injection (mo(u)lding) machine, which is characterized in that including BMC material, metered charge plunger, injection column
Plug, injection cylinder, check valve, connecting bend, metered charge oil cylinder, injection head, injection mold cavities, the injection cylinder pass through injection
Plunger is connect with injection head, and the injection head is connect with check valve, and the check valve is connect with connecting bend, the connecting bend
It is connect with injection mold cavities, metered charge plunger is equipped in the injection mold cavities and is connected, BMC is equipped in front of the metered charge plunger
Material, the metered charge plunger are connect with metered charge oil cylinder.
Further, the BMC material is unsaturated poly-vinegar resin, be chopped the auspicious fiber of glass, fleut, crosslinking agent, solidification
The agglomerate material of the putty-like of agent and release agent composition.
Further, the metered charge plunger can be with helical rotation.
The invention has the following advantages that
1, due to the good fluidity of BMC, there is stable forming temperature；
2, low glass breakage rate；
3, there is stable injection volume.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of BMC injection (mo(u)lding) machine of the present invention；
In figure: BMC material 1, metered charge plunger 2, injection piston 3, injection cylinder 4, check valve 5, connecting bend 6, metering add
Material oil cylinder 7, injection head 8, injection mold cavities 9.
Specific embodiment
The present invention is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this technique
For the common process personnel in field, without departing from the principle of the present invention, to repairing for various equivalent forms of the invention
Change and falls within the application range as defined in the appended claims.
Embodiment 1:
Fig. 1 is a kind of BMC injection (mo(u)lding) machine of the present invention, which is characterized in that including BMC material 1, metered charge plunger 2, injection
Plunger 3, injection cylinder 4, check valve 5, connecting bend 6, metered charge oil cylinder 7, injection head 8, injection mold cavities 9, the injection oil
Cylinder 4 is connect by injection piston 3 with injection head 8, and the injection head 8 is connect with check valve 5, the check valve 5 and connecting bend 6
Connection, the connecting bend 6 are connect with injection mold cavities 9, are equipped with metered charge plunger 2 in the injection mold cavities 9 and are connected, the meter
It is equipped with BMC material 1 in front of amount charging plunger 2, the metered charge plunger 2 is connect with metered charge oil cylinder 7.
Further, the BMC material 1 is unsaturated poly-vinegar resin, be chopped the auspicious fiber of glass, fleut, crosslinking agent, solidification
The agglomerate material of the putty-like of agent and release agent composition.
Further, the metered charge plunger 2 can be with helical rotation.
Working principle: injection mold cavities, the metered charge plunger that BMC material rear is equipped with, metered charge is added in BMC material
Plunger carries out movement processing by oiling oil cylinder, and charging material is squeezed, and enter injection head by connecting bend
In, and come out by injection head.
The invention has the following advantages that
1, due to the good fluidity of BMC, there is stable forming temperature；
2, low glass breakage rate；
3, there is stable injection volume.
