Description
Technical field
The utility model relates to injection-moulding device technical field, is specifically a kind of injection machine lock shaft fixing device.
Background technology
Three-plate type injection machine conventionally adopts in connecting rod and turns over formula mould-matching structure, adopts lock shaft series connection between tailgate, connecting rod and moving die plate, and connecting rod rotates centered by lock shaft, realizes the rectilinear motion of moving die plate by relatively rotating between connecting rod.Wherein lock shaft generally adopts the mode of pressing plate axial restraint, lock shaft and template are fixed together, be placed between falsework by connecting rod, lock shaft penetrates from falsework one side, and connect successively support and connecting rod, be provided with groove at the end face of support, after concordant with bracket end face to lock shaft end face, one pressing plate is embedded in groove, and be screwed, seal lock shaft.
Adopt above-mentioned fixed form, due to the needs of part processing and assembling, lock shaft diameter adopts negative common difference, falsework hole adopts plus tolerance, and both exist gap, in use, owing to being subject to the variation of force direction, the relative falsework of lock shaft hole exists periodic distance to move around, and causes mechanical oscillation, produces noise.And owing to there is mismachining tolerance and rigging error, the depth of parallelism of lock shaft and stencil plane does not reach perfect condition, when serious, can cause lock shaft axial float, cause axial pressing plate hold-down screw fracture, reduce service life of equipment.
Utility model content
The technical problems to be solved in the utility model is that a kind of lock shaft axial float and less injection machine lock shaft fixing device of noise of effectively preventing is provided.
Technical solution of the present utility model is, a kind of injection machine lock shaft fixing device is provided, comprise template, the lock shaft of multiple connecting rods and connect successively template and connecting rod, described template edge is provided with the support for the connecting rod of connecting, on described each support, all have vertical through holes, described support outside has a breach being communicated with vertical through holes, on described support, be provided with a through hole being communicated with breach away from one end of template, described through hole is unthreaded hole, one end near template on described support is provided with a blind hole being communicated with breach, described blind hole is screwed hole, the axis of described unthreaded hole and the axis of screwed hole are on same straight line, and vertical with the axis of vertical through holes, described injection machine lock shaft fixing device also comprises housing screw, described housing screw coordinates with screwed hole through unthreaded hole.
Adopt the injection machine lock shaft fixing device of above structure compared with prior art, have the following advantages: the structure of support gap, allow on support the vertical through holes dimensional tolerance for lock shaft is installed large, be convenient to processing and lock shaft and axially install; The fixed form of lock shaft is changed into radially and being fixed by axial restraint, reduced the coherence request of lock shaft length and falsework distance; Screw is tightened to screwed hole through unthreaded hole, and breach dwindles, and falsework diameter diminishes, and support is tightly embraced lock shaft, has eliminated gap between the two, has reduced the mechanical oscillation noise in use procedure; Support in template is generally multiple, and multiple spot obvolvent is completely fixed in template lock shaft, and huge screw in compression power effectively prevents the axial float of lock shaft, has improved equipment traveling comfort, improves the service life of equipment.
As improvement, described connecting rod series of holes is embedded with steel bushing, and described steel bushing and lock shaft are rotatably assorted, and that avoids lock shaft and connecting rod directly contacts the wearing and tearing that cause, steel bushing can be replaced, and has improved the service life of equipment.
As improvement, described steel bushing inwall is provided with helicla flute, and described spiral fluted cross section is semicircle, and semicircular helicla flute is used for adding lubricating oil, increases the lubricity of equipment, effectively avoids wearing and tearing.
As improvement, described gap width is 3mm-5mm, is convenient to processing, and can effectively ensure that screw can tighten the fixing lock shaft of support.
