Abstract
The invention relates to a large-sized injection mold cutting-up board supporting structure. The large-sized injection mold cutting-up board supporting structure comprises a supporting column 1, a supporting surface 2, a guide column 3 and a countersunk bolt 4, wherein the guide column 3 and the supporting column 1 stay on the same axis and are connected with each other through the countersunk bolt 4, and the diameter of the guide column 3 is smaller than that of the supporting column 1. The supporting structure is used for supporting a large-sized cutting-up board, so that the deformation of the cutting-up board can be effectively prevented; further, by controlling the tolerance of the supporting column and the guide column, the cutting-up board can be precisely supported on the same plane, and the plane precision of the cutting-up board can be further guaranteed; by controlling the width of the supporting surface, the supporting area of the cutting-up board can be increased, and the supporting area of the cutting-up board can be further guaranteed, so that the plane precision of the cutting-up board can be further guaranteed.
Description
Technical field
The design relates to large injection mold cut-out plate supporting construction, belongs to injection mold technical field.
Background technology
After plastic injection mo(u)lding, can leave stub bar at cast gate, need to carry out follow-up cleaning, this not only can increase follow-up workload, also can affect machining accuracy and the surface smoothness of plastic, affects the working (machining) efficiency of plastic, and this is particularly evident large-scale plastic parts.General processing mode can increase a cut-out plate, for eliminating the formation of cast gate stub bar between punch-die, the cut-out plate of large-scale plastic parts is because area is large, correspondingly the area of cut-out plate and weight are also large, for preventing cut-out plate distortion, the supporting construction of cut-out plate need to be set.
Summary of the invention
For the deficiencies in the prior art, the design's object is to provide a kind of large injection mold cut-out plate supporting construction.
For achieving the above object, the design realizes by following technological means:
A large injection mold cut-out plate supporting construction, is characterized in that: comprise support column 1, supporting surface 2, lead 3, dormant bolt 4; Described lead 3 is positioned on same axial line with described support column 1, and both connect by dormant bolt 4, and the diameter of described lead 3 is less than the diameter of described support column 1.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: the diameter of described lead 3 is less than the diameter 10mm of described support column 1.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: the height tolerance of described support column 1 is 0--+0.05mm, the height tolerance of described lead 3 is 0.05-0.10mm.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: hexagonal M6 bolt in described dormant bolt 4 adopts.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: at least 4 of described supporting constructions, are distributed in cut-out plate.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: the material of described supporting construction is P20.
The invention has the beneficial effects as follows: by large-scale cut-out plate is arranged to supporting construction, can effectively prevent the distortion of cut-out plate; Further, by the allowance control to support column and lead, can make cut-out plate be supported on accurate same plane, guarantee further the plane precision of cut-out plate; The control of supporting surface width, can increase the Area of bearing of cut-out plate, has further guaranteed the Area of bearing of cut-out plate, thereby has further guaranteed the plane precision of cut-out plate.
Accompanying drawing explanation
Fig. 1 is the design's perspective view.
The implication of drawing reference numeral is as follows: 1 support column, 2 supporting surfaces, 3 leads, 4 dormant bolts.
The specific embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, a kind of large injection mold cut-out plate supporting construction, is characterized in that: comprise support column 1, supporting surface 2, lead 3, dormant bolt 4; Described lead 3 is positioned on same axial line with described support column 1, and both connect by dormant bolt 4, and the diameter of described lead 3 is less than the diameter of described support column 1.
This supporting construction, bears the weight of cut-out plate by supporting surface 2, avoid its distortion, affects the precision that cuts of cut-out plate; Lead 3 adopts dormant bolt 4 to be connected with support column 1, can make lead 3 and support column 1 separate manufacture, is convenient to guarantee the accuracy of manufacture.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: the diameter of described lead 3 is less than the diameter 10mm of described support column 1.
Can make the monolateral support width of supporting surface 2 be greater than 5mm, effective increase Area of bearing.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: the height tolerance of described support column 1 is 0--+0.05mm, the height tolerance of described lead 3 is 0.05-0.10mm.
By controlling lead 3 and support column 1 height tolerance, can control the planar support precision of cut-out plate, avoid due to the plane precision that supports obliquity effects cut-out plate.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: hexagonal M6 bolt in described dormant bolt 4 adopts.
This kind of bolt low price, be convenient to installing/dismounting.
Preferably, described a kind of large injection mold cut-out plate supporting construction, is characterized in that: at least 4 of described supporting constructions, are distributed in cut-out plate.
Increase the smoothness supporting.
