Abstract
The invention relates to a die adjustment nut for a die casting machine. The die adjustment nut comprises a body, gear rings on the outer side of the body as well as a big lever matched and connected with the body, wherein the section of the body is shaped like a Chinese character 'tu', the gear rings are arranged at the outer side of the big ends of the body, the small ends of the body are cones, and the big ends are twice as long as the small ends; and the body is internally equipped with a compression device which comprises a connection rod, an elastic piece, a base and a compression block, wherein a connection rod shaft is connected in the body, one end of the connection rod shaft extends out of the surface of the body and the other end of the connection rod shaft is embedded into the compression block, the elastic piece is arranged at the upper part of the compression block, the base is arranged at the side part of the compression block, the lower part of the compression block is provided with bulges, and the bulges are arranged corresponding to grooves on the big lever. By adopting the improved structure, the die adjustment nut has the advantages that stress can be gradually dispersed by the cones so as to reduce stress concentration at a thread of the big lever and effectively lower the probability of fatigue fracture of the big lever; and the body is internally equipped with the compression device, thereby preventing the die adjustment nut from rotating on the big lever, and further ensuring more stable and reliable operating performances.
Description
Technical field
The present invention relates to field of die casting machines, relate in particular to a kind of die casting machine mode transfer nut.
Background technology
For satisfying the requirement of different mold thickness; Realize that the distance between moving platen and the solid plate is adjustable; Mould adjusting mechanism commonly used is power output with the oil motor; Through cooperating of mode transfer nut and big thick stick as the power conversion structure, change the torque axis of oil motor output into promote the mould clutch power, reach desirable requirement.
Existing mode transfer nut comprises body, gear ring and screw thread, and template directly contacts with nut body, and it is prone to cause big thick stick screw thread place stress to concentrate, and very easily makes big thick stick screw thread fracture or conquassation, and stress is excessive even can make big thick stick fracture.Main material is the iron and steel manufacturing in addition, and intensity and wearability are relatively poor relatively, and therefore, the structure of nut is necessary further improvement.
Summary of the invention
The technical problem that the present invention will solve is: a kind of rational in infrastructure, bearing capacity is strong, stress is less, reliable and stable die casting machine mode transfer nut is provided.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of die casting machine mode transfer nut comprises body, is arranged on the gear ring in the body outside and the big thick stick that is connected with body; Said body section is convex shape, holds arranged outside that gear ring is arranged greatly, and small end is a cone; Be provided with hold down gag in the body, said hold down gag comprises connecting rod, elastic component, base, compact heap, and said pitman shaft is connected in nut inside; One end stretches out body; The other end embeds in the compact heap, and said elastic component is arranged on compact heap top, and said base is arranged on the compact heap sidepiece; The compact heap bottom has convexity, the corresponding setting of groove on said convexity and the big thick stick.
According to another embodiment of the invention, a kind of die casting machine mode transfer nut comprises that further said body is connected through key with gear ring.
According to another embodiment of the invention, a kind of die casting machine mode transfer nut comprises that further the junction of said big end and small end is provided with arc-shaped ring groove.
According to another embodiment of the invention, a kind of die casting machine mode transfer nut comprises that further said big end length is the small end twice.
According to another embodiment of the invention, a kind of die casting machine mode transfer nut comprises that further said elastic component is a spring.
The invention solves the defective that exists in the background technology; After the architecture advances; The cone place can disperse stress gradually, reduces the stress at big thick stick screw thread place and concentrates, and effectively reduces the probability that big thick stick produces fatigue fracture; In body, be provided with hold down gag and can prevent that the mode transfer nut from rotating on big thick stick, more reliable and more stable when making work.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Wherein: 1, Da Gang, 2, body, 3, gear ring, 4, connecting rod, 5, compact heap, 6, elastic component, 7, base, 8, big end, 9, small end, 10, arc-shaped ring groove.
The specific embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of die casting machine mode transfer nut as shown in Figure 1 comprises body 2, is arranged on the gear ring 3 in body 2 outsides and the big thick stick 1 that is connected with body 2, and said body 2 and gear ring 3 are connected through key; Said body 2 cross sections are convex shape, hold 8 arranged outside that gear ring 3 is arranged greatly, and small end 9 is a cone; The length of said big end 8 is the twice of small end 9, is provided with hold down gag in the body 2, and said hold down gag comprises connecting rod 4, elastic component 6, base 7, compact heap 5; 4 on said connecting rod is connected in body 2 inside, and an end stretches out body 2, and the other end embeds in the compact heap 5; Said elastic component 6 is arranged on compact heap 5 tops, and elastic component 6 is a spring, and said base 7 is arranged on compact heap 5 sidepieces; Compact heap 5 bottoms have convexity, the corresponding setting of groove on said convexity and the big thick stick 1.
Said big end 8 is provided with arc-shaped ring groove 10 with the junction of small end 9, and when stressed, small end 9 cones of mode transfer nut can the stress effect produce slight bending, and stress can disperse at the cone place gradually like this, reduces big thick stick 1 effectively and produces the probability of fatigue fracture.
For preventing the rotation on big thick stick 1 of mode transfer nut, cause key and the dislocation of the keyway on the gear ring 3 on the mode transfer nut body 2, on the mode transfer nut, hold down gag is housed, thereby on the big thick stick 1 that under the effect of elastic component 6 compact heap 5 is compressed, prevents the rotation of mode transfer nut.
Cone of the present invention place can disperse stress gradually, reduces the stress at big thick stick screw thread place and concentrates, and effectively reduces the probability that big thick stick produces fatigue fracture, in body, is provided with hold down gag and can prevents that the mode transfer nut from rotating on big thick stick, and is more reliable and more stable when making work.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
