Abstract
The utility model discloses a product demoulding and ejecting device for a thermal forming punching machine, and aims to provide the product demoulding and ejecting device for the thermal forming punching machine, which has the advantages that the device is independently positioned in a lower mould cavity, the ejection is smooth and the reliability is high, the failure rate of stuck of an ejectorrod is low, and the maintenance and the disassembly are convenient. The product demoulding and ejecting device comprises a fixation frame, the ejector rod and the spring, the lower part of the fixation frame is mounted in the machine body, an opening is formed at the upper part of the fixation frame, the ejector rod is mounted in the opening, the upper part of the ejector rod extends out of the fixation frame, the lower part of the ejector rod is connected with the spring, the other end of the spring is fixed, and the ejector rod is connected in a sliding manner with the fixation frame in axial direction.
Description
Technical field
The utility model relates to a kind of structural improvement of sheet heat forming punching out machine, refers to a kind of product stripping liftout attachment of thermoforming punching out machine especially.
Background technology
Thermoforming punching out machine comprises body, heater, transmission device, decompressor, upper die and lower die, in the production process, the sheet material that heats is delivered to up and down in the middle of the mould, start decompressor and drive patrix and move down sheet material is carried out punch forming, eject by the product of ejecting mechanism after then moulding.The product stripping liftout attachment of the thermoforming punching out machine of prior art is fixed together with the counterdie die cavity, ejects steadily, reliability is low, and the stuck fault rate of push rod is higher.And repair demolition is pretty troublesome, and maintenance time is longer.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model be to provide a kind of be independent of the counterdie die cavity, eject steadily, reliability is high, the product stripping liftout attachment of the lower and repair demolition thermoforming punching out easily machine of the stuck fault rate of push rod.
The technical scheme that its technical problem that solves the utility model adopts is: include fixed frame, push rod, spring, the fixed frame bottom is loaded on body, opening is arranged at top, push rod is housed in the opening, fixed frame is stretched out on the top of push rod, the bottom is connected with spring, the other end of spring is fixed, and push rod becomes to be in axial sliding connection with fixed frame.
When push rod was in free state, spring upwards pushed up push rod to upper dead center position during work, exceeded cutting die face certain distance in the top.This distance be exactly push rod effectively eject the position.During matched moulds, push rod at first touches sheet material it is overlayed on the heating panel, and along with mold notch moves closer to the heating panel, push rod also slowly is retracted in the mould.After the thermoforming formed product was finished, mould can leave the heating panel gradually, and this moment, push rod pressed down product to pressing product outwards to eject in spring action.The also corresponding disengaging die cavity of product is finished knockout course simultaneously.
The beneficial effects of the utility model are: liftout attachment is independent of the counterdie die cavity, eject steadily, reliability is high, and the stuck fault rate of push rod is lower and repair demolition convenient.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Among the figure: 1 is that body, 2 is that fixed frame, 3 is that spring, 4 is that push rod, 5 is that guide pillar, 6 is that contiguous block, 7 is a plug.
The specific embodiment
Referring to accompanying drawing, of the present utility model being characterised in that; Include fixed frame 2, push rod 4, spring 3, body 1 is fixed in fixed frame 2 bottoms, opening is arranged at top, and push rod 4 is housed in the opening, and fixed frame 2 is stretched out on the top of push rod 4, the bottom is connected with spring 3, the other end of spring 3 is fixed on the fixed frame 2, and push rod 4 is in axial sliding connection for 2 one-tenth with fixed frame.
In first embodiment of the present utility model, push rod 4 bottoms are hollow, and spring 3 one ends stretch into its hollow inside, and the hollow wall of push rod 4 plays the role of positioning to spring 3, by cooperating of push rod 4 external diameters and fixed frame 2 internal diameters, make fixed frame 2 internal diameters play the helical pitch effect to push rod 4.Screw thread is arranged at the bottom of fixed frame 2, and fixed frame 2 is connected with plug 7 on being fixed in body 1 by this screw thread, thereby makes fixed frame 2 and body 1 strong bonded.
In second embodiment of the present utility model, a contiguous block 6 and guide pillar 5 are arranged, push rod 4 bottoms are connected with contiguous block 6, and contiguous block 6 is slidingly connected for 5 one-tenth with guide pillar, and guide pillar 5 can be loaded in the fixed frame 2 or on the body 1, the mobile effect of playing guide rail of 5 pairs of push rods 4 of guide pillar.
