Greatly, in use, situations such as rotating, exiting also can often occur, but for mold insert, the gap precision of mold insert is very high,
The movement of oil cylinder can cause the gap of mold insert to increase, bad so as to cause product quality.
Utility model content
The utility model discloses a kind of die cylinder anti-rotation devices, with so as to solve the deficiencies in the prior art.
To solve the above problems, the technical solution of the utility model is：
A kind of die cylinder anti-rotation device, including upper fixed seat, lower fixed seat and oil cylinder, the cylinder body installation of the oil cylinder
On upper fixed seat, axle sleeve is installed, there are one the first oil cylinder axis, the end sets of the first oil cylinder axis for oil cylinder tool on lower fixed seat
There is the second oil cylinder axis coaxial with the first oil cylinder axis, two anti-rotation faces parallel to each other, the second oil cylinder are set on the second oil cylinder axis
Axis is mounted in axle sleeve, and two planes of the cooperation that is in contact with anti-rotation face are provided in axle sleeve, outer lateral spacing is provided on the outside of axle sleeve
Plane, on axle sleeve installation be provided with fixed plate lateral surface on the outside of anti-rotation fixed plate, inside is provided with U there are one anti-rotation fixed plate
Shape slot, parallel surface and the anti-rotation face of the both sides of U-lag are engaged, outside confined planes and corresponding fixed plate lateral surface position
In on same plane.
The utility model has the beneficial effects that：By this oil cylinder anti-rotation device, oil cylinder can be effectively prevent to rotate, to protect
Card mold insert will not move in use, so as to improve the injection molding precision of product, improve the quality of product.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the scheme of installation of the utility model；
In figure：1- upper fixed seats, 2- lower fixed seats, 3- oil cylinders, 4- axle sleeves, 5- anti-rotation fixed plates, 31- the first oil cylinder axis,
32- the second oil cylinder axis, 33- anti-rotations face, confined planes on the outside of 41-, 51- fixed plate lateral surfaces.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to attached drawing 1-2, the utility model includes upper fixed seat 1, lower fixed seat 2 and oil cylinder 3, the cylinder of the oil cylinder 3
Body is mounted on upper fixed seat 1, axle sleeve 4 is equipped on lower fixed seat 2, there are one the first oil cylinder axis 31, the first oil cylinders for the tool of oil cylinder 3
The end set of axis 31 has a second oil cylinder axis 32 coaxial with the first oil cylinder axis 31, and setting two is mutually equal on the second oil cylinder axis 32
Capable anti-rotation face 33, the second oil cylinder axis 32 are mounted in axle sleeve 4, are provided in axle sleeve 4 and are in contact the two of cooperation with anti-rotation face 33
A plane, the outside of axle sleeve 4 are provided with outside confined planes 41, and installation is there are one anti-rotation fixed plate 5 on axle sleeve 4, outside anti-rotation fixed plate 5
Side is provided with fixed plate lateral surface 51, and inside is provided with U-lag, and parallel surface and the anti-rotation face of the both sides of U-lag are engaged,
Outside confined planes 41 and corresponding fixed plate lateral surface 51 are in the same plane.
In practical applications, the cylinder body of oil cylinder 3 is mounted on upper fixed seat 1, and axle sleeve 4, oil cylinder are equipped on lower fixed seat 2
For 3 tools there are one the first oil cylinder axis 31, the end set of the first oil cylinder axis 31 has the second oil cylinder axis coaxial with the first oil cylinder axis 31
32, two anti-rotation faces 33 parallel to each other are set on second oil cylinder axis 32, and the second oil cylinder axis 32 is mounted in axle sleeve 4, in axle sleeve 4
Two planes of the cooperation that is in contact with anti-rotation face 33 are provided with, 4 outside of axle sleeve is provided with outside confined planes 41, is installed on axle sleeve 4
There are one anti-rotation fixed plate 5,5 outside of anti-rotation fixed plate is provided with fixed plate lateral surface 51, and inside is provided with U-lag, U-lag
The parallel surfaces of both sides be engaged with anti-rotation face, outside confined planes 41 are located at same flat with corresponding fixed plate lateral surface 51
On face, when the first oil cylinder axis 31 on during oil cylinder 3 is such as figure moves up and down, the second oil cylinder axis 32 can also move together, and second
There are two anti-rotation faces 33 parallel to each other for processing on oil cylinder axis 32, and are moved with the shaft hole matching of axle sleeve 4, are provided in axle sleeve 4
Be in contact two planes of cooperation with anti-rotation face 33, can prevent in this way oil cylinder the first oil cylinder axis 31 and the second oil cylinder axis 32 not
It can rotate, meanwhile, fixed plate lateral surface 51 is provided with to the first oil cylinder axis 31 and the second oil cylinder axis by 5 outside of anti-rotation fixed plate
32 carry out accurate limiting, prevent its rotation, can ensure that the mold components such as the mold insert being connect on lower fixed seat 2 will not in this way
Situations such as with loosening, so as to improve the precision of mold, also, after the mold time having used long, due to the first oil
Cylinder shaft 31 and the second oil cylinder axis 32 have abrasion with axle sleeve 4 and anti-rotation fixed plate 5, at this time, it is only necessary to change axle sleeve 4 or anti-rotation is solid
Fixed board 5 does not have to replace other components, also saves mold use cost.
Above-mentioned specific implementation mode is the preferred embodiment of the utility model, can not be defined to the utility model,
Other any changes made without departing from the technical solution of the utility model or other equivalent substitute modes, are included in
Within the scope of protection of the utility model.
