Description
Technical field
The invention belongs to vertical extruder squeeze casting technology field, especially a kind of vertical extruder metal die oil cylinder
Ejecting mechanism and its extrusion method.
Background technique
The direction of motion and discharging direction of the main component of vertical extruder are perpendicular to the ground, so occupied area is small, but
More demanding workshop and deeper melt pit.The latter is in order to which the pipe for guaranteeing extrusion is straight and rounding, so as to subsequent pickling
Cold rolling or with core print drawing.Because moving component moves perpendicular to the ground, so abrasion is small, deforms uniformly, squeeze after component expanded by heating
Press center is not easy to lack of proper care, pipe bias very little.The ability maximum of extruder is more than 15MN, is commonly 6-10MN, main to use
Make production size little tubing and hollw article.
During small extruding machine extrusion casint, there are many minitype vertical type extruders since structure is simple, lacks necessary
Ejecting mechanism, extruded product needs manpower to demould after die sinking, and production efficiency is low, and production cost is higher, due to extruding metal system
Product temperature also with higher after the completion of extruding, using manpower demoulding also have certain risk or ejecting mechanism by
Restriction in position cannot push up in place, cause extruded product to occur breaking or the phenomenon that drawing crack, cause to squeeze and produce
The damage of product.
Summary of the invention
The present invention provides a kind of structure is simple, easy to process, assembly, workpiece can be convenient reliably eject vertical and squeeze
Press metal die cylinder ejector mechanism and its extrusion method.
In order to solve the above technical problems, technical solution adopted by the present invention is: a kind of vertical extruder metal die
Cylinder ejector mechanism includes oil cylinder, and oil cylinder is fixed below upper plate, and the cylinder rod of oil cylinder is connected with thimble panel, Ejector Retainer Plate
It is arranged between thimble panel and lower plate, upper plate is connected with lower plate by 2 supporting blocks and 2 supporting block difference positions
In oil cylinder two sides, upper plate is equipped with thermal insulation board I, and 2 are respectively equipped with thermal insulation board II and thermal insulation board between supporting block and lower plate
III, thimble one end and Ejector Retainer Plate are connected, and the other end passes through lower plate；It is fixed on lower plate at the top of metal die.
The lower plate is equipped with the through-hole that thimble passes through.
The thimble head is equipped with flange, is fixed on Ejector Retainer Plate in the form of flange.
The upper plate is bolted with supporting block.
It is provided with U-lag on the upper plate, can be connected by U-lag and bolt with vertical extruder sliding block.
The quantity of the thimble and position can be configured according to the position of specific mold extrusion sections.
The extrusion method of above-mentioned vertical extruder cylinder ejector mechanism ejecting structure is as follows:
1) after the completion of extrusion process, mold die sinking；
2) under the drive of cylinder thrust, cylinder rod pushes thimble panel, moves downward Ejector Retainer Plate and thimble, thimble contact
Extruded product, extruded product forces abjection under the promotion of thimble from mold, to complete whole stripping actions.
Apparatus of the present invention structure is simple, and easy to process, assembly, workpiece, which can be convenient, reliably to be ejected, and knock-pin is easy to more
It changes, a set of ejection system is suitable for multiple sets of molds, and simplifies mould structure, reduces mold difficulty and cost, shortens
Mold developing cycle improves economic benefit.

Specific embodiment
Below by embodiment, invention is further described in detail, but the scope of the present invention is not limited in described
Hold.
Embodiment 1: as shown in Figs 1-4, this vertical extruder metal die cylinder ejector mechanism includes oil cylinder 10, oil cylinder 10
It is fixed on 2 lower section of upper plate, the cylinder rod 11 of oil cylinder is connected with thimble panel 5, and the setting of Ejector Retainer Plate 7 is in thimble panel 5 under
Between bottom plate 8, upper plate 2 is connected with lower plate 8 by 2 supporting blocks 3 and 2 supporting blocks are located at oil cylinder two sides, on
Bottom plate 2 is equipped with thermal insulation board I 1,2 and is respectively equipped with thermal insulation board II 4 and thermal insulation board III 6, thimble 9 between supporting block 3 and lower plate 8
One end and Ejector Retainer Plate 7 are connected, and the other end passes through the through-hole on lower plate 8；It is fixed on lower plate 8 at the top of metal die.
