Abstract
The utility model discloses a kind of die opening mechanism for extrusion die die sinking; comprise point mould and the pushing oil cylinder for promoting point mould movement; described point of mould is connected with the piston rod of pushing oil cylinder, and described point of mould is disc structure, and the edge of disc structure is pyramidal structure.Adopt hydraulic machinery mode by extrusion die upper and lower mould detached job, greatly improve the operating efficiency of die sinking, reduce the labour intensity of workman, reduce costs; And die sinking process safety, steadily, reliable, avoid damaging the person of operator or extrusion die in die sinking process.
Description
Technical field
The utility model relates to mould open molding techniques field, especially relates to a kind of die opening mechanism for extrusion die die sinking.
Background technology
In aluminium section bar manufacturing, need to utilize extruding die for aluminum shaped material (cellular type divergent die) that aluminium ingot base is squeezed into section bar; In Extrusion Process of Aluminum Alloy Profile production process, the Contact of aluminium section bar and nib is Metal Contact, can cause wearing and tearing to extrusion die; After extrusion die uses certain hour, need extrusion die upper and lower mould to be separated to repair, save die cost; But be sticked together by aluminium material between the upper and lower mould of extrusion die, be difficult to open.
Generally utilize the mode of drift hand bumping to carry out die sinking in current industry, there is die sinking efficiency low, the defect that labor strength is large, and manual die sinking is often because operative is careless or tired operation damages to the person and mould, security is very difficult to be ensured.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of die opening mechanism for extrusion die die sinking, to reach die sinking safety, efficiently object.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
This is used for the die opening mechanism of extrusion die die sinking, comprises point mould and the pushing oil cylinder for promoting point mould movement, and described point of mould is connected with the piston rod of pushing oil cylinder, and described point of mould is disc structure, and the edge of disc structure is pyramidal structure.
Further, the motor also comprising rotating shaft and drive point mould to rotate, motor is connected with a point mould by rotating shaft.
Described point of mould is four points of moulds be arranged on the same face, and the center of four points of moulds is circumferentially same.
In 45 ° between the upper lower inclined plane at the disc structure edge of described point of mould and horizontal plane.
Described motor is hydraulic motor.
The utility model compared with prior art, has the following advantages:
Adopt hydraulic machinery mode by extrusion die upper and lower mould detached job, greatly improve the operating efficiency of die sinking, reduce the labour intensity of workman, reduce costs; And die sinking process safety, steadily, reliable, avoid damaging the person of operator or extrusion die in die sinking process.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is the utility model die opening mechanism structural representation.
In figure: 41. pushing oil cylinders, 42. guide rails, 43. hydraulic motors, 44. rotating shafts, 45. points of moulds.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1; this is used for the die opening mechanism of extrusion die die sinking, comprises pushing oil cylinder 41, guide rail 42, hydraulic motor 43, rotating shaft 44, point mould 45, wherein; hydraulic motor 43 is used for driving a point mould 45 to rotate, and pushing oil cylinder 41 is used for promoting point mould 45 translation.
Hydraulic motor 43 is all connected with external hydraulic pump with pushing oil cylinder 41, and point mould is connected by the piston rod of guide rail with pushing oil cylinder; Divide mould 45 to have four, two are arranged in the relative both sides of workbench for a pair.Four points of moulds are arranged in same plane, and the center of four points of moulds is circumferentially same.Stress balance, die sinking is steady.
Mould 45 is divided to be disc structure, the edge cross-section of disc structure is tapered cross-section, angle between the upper lower inclined plane at the edge of disc structure and horizontal plane can be 45 °, enters in the Separation between mould upper and lower mould by the edge of disc structure, is separated upper and lower mould.
Hydraulic motor 43 is connected by the center of rotating shaft with point mould 45, drives a point mould 45 to rotate, be convenient to quick separating upper and lower mould by hydraulic motor 43.
Pushing oil cylinder 41 is symmetrically arranged a pair, and the split pattern dish 45 that the pushing oil cylinder 41 of side promotes to be positioned at this side by guide rail 42 moves in the middle part of workbench; The split pattern dish that the pushing oil cylinder of opposite side promotes to be positioned at this side by guide rail moves in the middle part of workbench, and a point mould for corresponding both sides moves synchronously, and the rotation direction of four points of moulds 45 is consistent.
Extrusion die to be separated is placed on workbench, the Separation between mould and extrusion die upper and lower mould is divided to align, pushing oil cylinder pushing divides mould to move to extrusion die, mould will be divided to push between upper and lower mould in Separation, parting disc spins simultaneously, be separated by extrusion die upper and lower mould, four points of moulds are from four direction peel of mould, the upper and lower mould stress equalization of extrusion die, separation safely, steadily.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present utility model and technical scheme are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
