Description
Technical field
The present invention relates to injection machine accessory structure field, particularly a kind of adjustment mould plate of injection machine.
Background technology
Adjustment mould plate (also claiming tailgate) is a very important major part on injection machine; adjustment mould plate, by the connection of connecting rod, connection between connecting rod and connecting rod, connecting rod and moving platen (also claiming two plates), forms the moving component of injection molding machine mold clamping mechanism matched moulds together.Adjustment mould plate, moving platen, solid plate (also claim head plate) being fixedly connected with by parts such as pull bar, pull-rod nut, adjustment nuts, constitute the most main part of whole injection molding machine mold clamping mechanism.
Existing conventional injection machine adjustment mould plate, usually because unbalance stress is yielding, easily damages.Adjustment mould plate generally comprises front and back, and front is common mould adjusting mechanism installed surface, and the back side is connecting rod installed surface or casts with connecting rod and become an overall structure.Adjustment mould plate front is provided with Mode-locking oil cylinder, stretches and extrude the alternate stress of two aspects by Mode-locking oil cylinder, and the pull bar at four angles, front and adjustment nut also can produce extruding to adjustment mould plate and cause diastrophic power.The bar linkage structure at the adjustment mould plate back side also produces the powerful extruding force of adjustment mould plate when locked mode moves, thus causes the flexural deformation of adjustment mould plate.The adjustment mould plate of injection machine is due to the needs of Mode-locking oil cylinder mounting structure, and center has macropore, and when processing plastic goods, adjustment mould plate easily produces distortion due to unbalance stress, thus damages adjustment mould plate, and this is also the more common defect of existing injection machine adjustment mould plate.
Summary of the invention
The object of the invention is the defect existed for above-mentioned prior art, there is provided a kind of injection machine high strength adjustment mould plate, its intensity is high, long service life, effectively can improve stability, the kinematic accuracy of injection moulding machine mode-locking motion, and then improve the qualification rate of plastic products.
The technical scheme that the present invention adopts for achieving the above object is: a kind of injection machine high strength adjustment mould plate, comprise stencil body, stencil body comprises template front and template back surface, surrounding lateral margin between template front and template back surface is connected to form formwork sides, in described template front and template back surface, at least the outer surface of one of them is the curved surface of outwardly convex, described template is positively connected with and is connected with template front and is the disjunctor connecting rod twisted seat of integral type structure with it, and described stencil body is also provided with multiple stress relief hole.
Further technical scheme of the present invention is: described stencil body is UFO-shape.
Further technical scheme of the present invention is: the outer surface in described template front is the curved surface of outwardly convex, and disjunctor connecting rod twisted seat is connected on the curved surface in template front of outwardly convex.
Further technical scheme of the present invention is: the outer surface of described template front and template back surface is all the curved surface of outwardly convex, disjunctor connecting rod twisted seat is connected on the curved surface in template front of outwardly convex, and Mode-locking oil cylinder installs the middle part that end face is arranged on template back surface curved surface.
Further technical scheme of the present invention is: described stress relief hole comprises the stress relief hole I be arranged on template front and template back surface, and stress relief hole I has four at least.
Further technical scheme of the present invention is: described stress relief hole comprises the stress relief hole II be arranged on formwork sides, and stress relief hole II has four at least.
Further technical scheme of the present invention is: described stencil body is case structure, between template front, template back surface and formwork sides, be namely provided with the inner chamber of hollow.
Injection machine high strength adjustment mould plate of the present invention has following beneficial effect: because template is positively connected with the disjunctor connecting rod twisted seat of integral structure, disjunctor connecting rod twisted seat and stencil body stable connection; By in template front and template back surface, at least one of them is set to curved surface, template front or template back surface are designed to curved surface, the template front or the template back surface that make to be designed to curved surface can be larger at the position radian by middle part, make formwork integral bending resistance, non-deformability comparatively strong, meet the requirement of mechanical structure; Template front or template back surface or formwork sides are provided with multiple stress relief hole, effectively can reduce stress and concentrate; When injection machine closed die, pull bar applies mold clamping force F1 to adjustment mould plate four angles, F1 directly acts on template back surface, disjunctor connecting rod twisted seat is subject to the mold clamping force F2 that linkage applies, F2 directly acts on template front by disjunctor connecting rod twisted seat, Mode-locking oil cylinder is exerted a force by oil cylinder linkage and obtains reaction force F3 simultaneously, and F3 directly acts on template back surface by Mode-locking oil cylinder.After using high strength adjustment mould plate of the present invention, adjustment mould plate can be made to be out of shape in the process of locking die little, thus the stability, the kinematic accuracy that realize improving job efficiency, improve locked mode motion, also well can protect pull bar simultaneously.
Below in conjunction with drawings and Examples, injection machine high strength adjustment mould plate of the present invention is further described.
