Abstract
The utility model discloses a kind of resetting-mechanism of ejector retainner plate ultralong-stroke, comprise the moving platen of upper end and the solid plate of lower end, the below of described solid plate is provided with the movable panel for controlling thimble, described solid plate lateral wall place is provided with hydraulic cylinder, described hydraulic cylinder is arranged with push rod, the edge of described movable panel is provided with contiguous block, and described push rod is connected with contiguous block; Described die returning mechanism is by rational structural improvement, and particularly replace spring by the combination of hydraulic cylinder, push rod and contiguous block, eject and the use that resets as ejector retainner plate, not only its mounting or dismounting become relatively easy, and service life is than the length of spring structure.
Description
Technical field
The utility model relates to a kind of mould structure, particularly a kind of ejector retainner plate resetting-mechanism for ejector retainner plate ultralong-stroke.
Background technology
Injection mold, after completing injection moulding, generally needs thimble to eject injection-molded finished, and then ejector retainner plate resets and uses spring or injection machine to retract by force.Wherein adopted its length is relevant with the stroke needing to eject, if such as there is larger oblique top of loosing core, then needs more than the long spring of 450mm.But in use find, overlength spring often installs and removes difficulty, and the life-span be worse than the spring of general length.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of more durable ejector retainner plate ultralong-stroke resetting-mechanism.
The utility model solves the technical scheme that its technical problem adopts:
A kind of resetting-mechanism of ejector retainner plate ultralong-stroke, comprise the moving platen of upper end and the solid plate of lower end, the below of described solid plate is provided with the movable panel for controlling thimble, described solid plate lateral wall place is provided with hydraulic cylinder, described hydraulic cylinder is arranged with push rod, the edge of described movable panel is provided with contiguous block, and described push rod is connected with contiguous block.
As a preference, left and right sides place, described solid plate bottom arranges the support be connected with base, and described movable panel is between the support of the left and right sides, and described contiguous block is between the support of homonymy.
As a preference, described contiguous block has step draw-in groove, and described push rod is arranged with step fastener, and described step fastener sticks in step draw-in groove.
As a preference, described contiguous block includes combination block and lower combination block, and described upper combination block has narrow groove, and described lower combination block has sipes, and described narrow groove and sipes are combined into step draw-in groove.
The beneficial effects of the utility model are: described die returning mechanism is by rational structural improvement, particularly replace spring by the combination of hydraulic cylinder, push rod and contiguous block, eject and the use that resets as ejector retainner plate, not only its mounting or dismounting become relatively easy, and service life is than the length of spring structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of resetting-mechanism of ejector retainner plate ultralong-stroke, comprises the moving platen 1 of upper end and the solid plate 2 of lower end, is provided with for injection-molded finished die cavity between moving platen 1 and solid plate 2.The below of described solid plate 2 is provided with the movable panel 3 for controlling thimble, and the thimble of movable panel 3 can stretch into die cavity and finished product is ejected.Described solid plate 2 lateral wall place is provided with hydraulic cylinder 4, and described hydraulic cylinder 4 is arranged with push rod 41, and the edge of described movable panel 3 is provided with contiguous block 5, and described push rod 41 is connected with contiguous block 5.After injection moulding completes, movable panel 3 rising controls thimble and finished product is ejected, then hydraulic cylinder 4 controls push rod 41 and movable panel 3 has been rolled back reset, and namely hydraulic cylinder 4, push rod 41 and contiguous block 5 are combined into a new resetting-mechanism and replace original spring structure.
Left and right sides place, described solid plate 2 bottom arranges the support 7 be connected with base 6, described movable panel 3 is between the support 7 of the left and right sides, described contiguous block 5 is between the support 7 of homonymy, namely 7 points, support is listed in movable panel 3 left and right sides, the gap of contiguous block 5 then between each support 7, both keep support 7 pairs of moulds and have enough support forces, also ensure that the resetting-mechanism of hydraulic cylinder 4, push rod 41 and contiguous block 5 combination has enough strength to promote movable panel 3, make the distribution of force of total more reasonable, increase the service life.
Described contiguous block 5 has step draw-in groove 8, and described push rod 41 is arranged with step fastener 9, and described step fastener 9 sticks in step draw-in groove 8, can make the easily easier for installation of contiguous block 5 and push rod 41 like this.
Described contiguous block 5 includes combination block 51 and lower combination block 52, described upper combination block 51 has narrow groove 81, described lower combination block 52 has sipes 82, described narrow groove 81 and sipes 82 are combined into step draw-in groove 8, so not only ease of assembly, and adapt to the stressing conditions of push rod 41, ensure that resetting structure is enough firm.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
