Abstract
The utility model relates to a kind of truss-like front mould board of injection machine, stress deformation situation analysis when being worked according to front mould board of injection machine, by being designed to front mould board of injection machine structure, realize that formwork rigidity height, mold mounting plate deform target small, that template is light-weight.The front template includes clamp force load plate, lattice supporting framework and mold mounting plate；The lattice supporting framework is the structure being formed by connecting by rod piece；Four pull rod guide holders of clamp force load plate install pull rod.Truss support is located in the middle part of clamp force load plate and mold mounting plate.The utility model has weight small, simultaneously because truss structure separates clamp force load plate and mold mounting plate surrounding, the characteristics of deformation caused by the power for applying pull rod concentrates on clamp force load plate and lattice supporting framework, reduces the displacement of mold mounting plate, and then improves injection-molded item precision.
Description
Technical field
The invention belongs to injector field, be important composition part in hydraulic elbow-bar mechanism injector clamping it
One, it is the important part for influencing mold stress deformation and injection-molded item precision.
Background technique
The structure design of front mould board of injection machine directly affects injection shaped article quality and manufacturing cost.Formwork structure shape
Formula determines the uniform situation of template with the mold stress deformation being installed on it, and is to realize that high rigidity and high injection molding precision are basic
It ensures.
The design of conventional injection machine front template structure is mostly occupied with the design of integral type rectangle hollow plate and internal arrangement reinforcing rib
More, structure type is single, total quality is big and at high cost.Traditional clamping generally by front template, moving template, rear pattern plate and
Crank mechanism composition.Die cylinder is moved forward by toggle mechanism urges moving template, utilizes mechanism power amplification characteristic locking die；Note
After the completion of penetrating, oil cylinder drives moving template to retreat by toggle mechanism, completes die sinking movement.In the locking of injector clamping,
Pulling force of the template side by corner location pull rod, mold mounting side is by the pressure from mold.It causes to be transmitted on mold
Clamp force it is uneven, template surrounding clamp force is big, and center stress is small.Clamping need to provide bigger clamp force ability
Meet mold-locked requirement, and pressure unevenness easily causes exhaust bad on mold, to influence injection-molded item quality；In addition, long
Phase clamp force, which is unevenly distributed, to be also unfavorable for protecting mold.
Summary of the invention
The present invention proposes a kind of new structural front mould board of injection machine structure type.Front template is broadly divided into three parts,
Clamp force load plate, mold mounting plate and intermediate connection transition portion, by rationally designing middle interconnecting piece point, and then realize and mention
High front template rigidity reduces manufacturing cost, avoids the stress occurred when work from concentrating, extends the purpose in service life.
To achieve the above object, the invention adopts the following technical scheme:
A kind of truss-like front mould board of injection machine, including clamp force load plate, lattice supporting framework and mold mounting plate；Truss
For support construction between clamp force load plate and mold mounting plate, mold mounting plate has the hole of installation mold, and truss support is
The truss structure being made of rod piece, for supporting mold clamping force and clamp force.
A kind of truss-like front mould board of injection machine of the present invention, is improved, lattice supporting framework is by rod piece group as a kind of structure
At pentahedron frame structure, template overall weight is smaller, has been remarkably improved the utilization rate of material.
A kind of truss-like front mould board of injection machine of the present invention, is improved as a kind of structure, at clamp force load plate tie rod hole,
Increase boss structure downwards, the rigidity of pull rod guide holder can be improved.
The present invention is compared with original technology: high by lattice supporting framework rigidity, light weight can make clamp force load plate stress
More uniform, mechanism is simple, easy to process；Template overall weight is smaller, significantly improves the utilization rate of material.Increase downwards convex
Platform structure improves the rigidity of pull rod guide holder.

Specific embodiment
A kind of truss-like front mould board of injection machine of the present invention, as shown in Figure 1, 2, 3, including clamp force load plate 1, truss support
2 and mold mounting plate 3.Wherein there are pull rod guide holder 5,1 lower surface of clamp force load plate and truss branch for 1 four jiaos of clamp force load plate
2 connection of support, wherein truss support 2 is made of the rod piece of a system, and lower surface and mold mounting plate 3 are fixed；In pull rod guide holder 5
There is boss structure 6 at place；T-slot 4 is provided on mold mounting plate 3.
A kind of truss-like front mould board of injection machine of the present invention is as shown in Figure 4,5 that the truss frame of lattice supporting framework is illustrated
Figure and truss base structure schematic diagram, what the pentahedron frame that truss structure is made of rod piece formed.Can by template by
Power be converted into rod piece receiving pulling force and pressure, saved mould material while improving the rigidity of template.
A kind of truss-like front mould board of injection machine of the present invention, pulling force of the clamp force load plate quadrangle by pull rod, mold installation
The mold clamping force given in the middle part of plate by mold, two power are in equilibrium state in the locked condition；Lattice supporting framework draws pull rod
Power is converted into lattice supporting framework pulling force and pressure between rod piece.This lattice supporting framework has the advantages that rigidity is high,
The quality of template is greatly alleviated simultaneously, and template deformation caused by draw-bar pull is concentrated in truss structure adding with clamp force
The square part of support plate, and deformation occurs substantially for mold mounting plate, ensure that the form and dimensional precision of injected articles.
