Description
Technical field
This utility model relates to plastic-injection moulding machine accessory structure field, particularly to the crosshead of a kind of plastic-injection moulding machine clamping mechanism.
Background technology
The crosshead of plastic-injection moulding machine clamping mechanism is for connecting piston and the link assembly of Mode-locking oil cylinder, and the power of piston is transmitted and decomposes to link assembly by crosshead, link assembly promote dynamic model motion.Existing crosshead is generally one flat " mouth " glyph framework structure, is provided with pilot hole at four angles of framework, and the thrust being subject to due to crosshead in locked mode process is very big, it is easy to deformation or fracture, and impact produces, and also increases production cost simultaneously.
Summary of the invention
The purpose of this utility model is the defect existed for above-mentioned prior art, it is provided that the crosshead of a kind of connecting rod eversion type plastic-injection moulding machine clamping mechanism, and its intensity is high, long service life.
This utility model the technical scheme is that the crosshead of a kind of connecting rod eversion type plastic-injection moulding machine clamping mechanism for achieving the above object, including two block frame bodies and be connected to the piston brace rod between two block frame bodies, Mode-locking oil cylinder piston connecting hole it is provided with in the middle part of piston brace rod, being respectively arranged at two ends with to turn forward of two block frame bodies extends to form linking arm, end, each linking arm front end is connected to the guide holder being connected as a single entity with linking arm, guide holder is provided with through the pilot hole of guide holder front/rear end, the relative guide holder of adjacent two block frame body end positions is connected by joint pin, the inner side of linking arm be tiltedly installed with simultaneously with linking arm inside, the ribs that frame body and guide holder connect.
Further technical scheme of the present utility model is: described piston brace rod includes piston brace rod I and the piston brace rod II relative with piston brace rod I position, Mode-locking oil cylinder piston connecting hole runs through piston brace rod I and piston brace rod II, piston brace rod I is vertically connected between in the middle part of two block frame body rear side surfaces, piston brace rod II includes by the bending section extended to form forward in the middle part of two block frame body front side surfaces and the connecting portion being connected between bending section, and the connecting portion of piston brace rod II is connected as a single entity by connection rib and piston brace rod I.
The crosshead of this utility model connecting rod eversion type plastic-injection moulding machine clamping mechanism has the advantages that being respectively arranged at two ends with to turn forward and extend to form linking arm due to two block frame bodies, the inner side of linking arm be tiltedly installed with simultaneously with linking arm inside, the ribs that frame body and guide holder connect, piston brace rod includes piston brace rod I and the piston brace rod II relative with piston brace rod I position, the intensity making crosshead is effectively strengthened, piston brace rod is connected in the middle of crosshead, thrust is effectively disperseed through the thrust dispersed structure of crosshead and is delivered on link assembly by cylinder thrust uniformly, overall structural reliability and safety are high especially.
Below in conjunction with drawings and Examples, the crosshead of this utility model connecting rod eversion type plastic-injection moulding machine clamping mechanism is further described.
