Abstract
The invention discloses an injection piston rod for a die-casting machine. The injection piston rod comprises a piston rod body (1), and is characterized in that a deep hole (2) is formed in one end of the piston rod body (1) in the axis direction of the piston rod body (1), and the ratio of the length of the deep hole (2) in the axis direction of the piston rod body (1) and the length of the piston rod body (1) in the axis direction ranges from 0.40 to 0.66. The deep hole is formed in one end of the piston rod body in the axis direction of the piston rod body, and the depth of the deep hole is controlled within a certain range with the consideration of the economical efficiency of punching and the influence of the depth of the deep hole on the strength of the piston rod body, so that the strength of the piston rod body is maintained on the basis that the self-weight of the piston rod body is reduced, and thus the speed of the piston rod in the injection process is increased.
Description
Technical field
The present invention relates to die casting machine technical field, specifically a kind of shot piston for die casting machine by reducing deadweight thus speed when can improve injection.
Background technology
One of machinery that machinery industry is conventional at die casting machine, for the die cast to product.Traditional die casting machine is primarily of six major part compositions: clamping, injection mechanism, frame, hydraulic drive mechanism, electrical control mechanism, safety door and other safety protective mechanisms, wherein clamping and injection mechanism are the core component of die casting machine.Shot piston of the prior art due to weight comparatively large, being therefore only improved injection power could improve injection speed, consumes energy greatly and effect is poor.
Summary of the invention
The object of the invention is for prior art Problems existing, a kind of shot piston for die casting machine by reducing speed when conducting oneself with dignity thus can improve injection is provided.
The object of the invention is to solve by the following technical programs:
A kind of shot piston for die casting machine, comprise piston rod body, it is characterized in that: the axis direction from one end of piston rod body along piston rod body has a deep hole, deep hole is 0.40 ~ 0.66 along the length of the axis direction of piston rod body and piston rod body along the length ratio of its axis direction.
Described deep hole is opened in that one end that piston rod body is connected with piston.
The openend of described deep hole adopts plug to block rear welding and polishes.
The present invention has the following advantages compared to existing technology:
The present invention has a deep hole by the axis direction from one end of piston rod body along piston rod body, and consider that the economy of punching and the degree of depth of deep hole are on the impact of piston rod body self-strength, thus by the severity control of deep hole in certain scope, thus keep the intensity of piston rod body on the basis reducing the deadweight of piston rod body, and then the speed of piston rod when improving injection.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-piston rod body; 2-deep hole.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 1: a kind of shot piston for die casting machine, comprise piston rod body 1, axis direction from one end of piston rod body 1 along piston rod body 1 has a deep hole 2, and deep hole 2 is 0.40 ~ 0.66 along the length of the axis direction of piston rod body 1 and piston rod body 1 along the length ratio of its axis direction.This deep hole 2 is opened in that one end that piston rod body 1 is connected with piston and the openend of deep hole 2 adopts plug to block, and then polishes after the position surrounding welding that plug is blocked.
The present invention has a deep hole 2 by the axis direction from one end of piston rod body 1 along piston rod body 1, and consider that the degree of depth of the economy of punching and deep hole 2 is on the impact of piston rod body 1 self-strength, thus by the severity control of deep hole 2 in certain scope, thus reducing the intensity basis that piston rod body 1 conducts oneself with dignity keeping piston rod body 1, and then the speed of piston rod when improving injection.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, every technological thought proposed according to the present invention, and any change that technical scheme basis is done, all falls within scope; The technology that the present invention does not relate to all is realized by prior art.
Claims (3)
1. the shot piston for die casting machine, comprise piston rod body (1), it is characterized in that: the axis direction from one end of piston rod body (1) along piston rod body (1) has a deep hole (2), deep hole (2) is 0.40 ~ 0.66 along the length of the axis direction of piston rod body (1) and piston rod body (1) along the length ratio of its axis direction.
