Abstract

The invention discloses a kind of Novel top ejecting plate, it is arranged between Bottom clamp plate and moving platen, liftout plate both sides are provided with mould foot, mould foot is fixed on Bottom clamp plate, described a kind of Novel top ejecting plate includes upper ejector plate and lower liftout plate, and upper ejector plate is fixed by trip bolt with lower liftout plate, and upper ejector plate and lower liftout plate are located between moving platen and Bottom clamp plate, the big centre of described upper ejector plate and lower liftout plate two is little, in " I shape ";The position of corresponding described upper ejector plate and lower liftout plate side is provided with mould foot, and described mould foot two is little broad in the middle.By the way, the present invention can solve the problem that liftout plate each installing hole interference problem, also can increase mould foot Area of bearing simultaneously, improves and ejects location and eject robust motion.

Description

A kind of liftout plate
Technical field
The present invention relates to injection mold mechanism field, particularly relate to a kind of liftout plate.
Background technology
Injection moulding be in a high voltage state by plastic melt with high speed injection to Guan Bi mold cavity in, after cooling and shaping, obtain plastic on all four with die profile.Due to the molding shrinkage of plastics, plastic part and running gate system after injection moulding are coagulated material and need to be disengaged it from mould by ejecting mechanism.Ejecting mechanism in injection mold typically has the forms such as push pedal release, push rod release, ejector sleeve release, release mode regardless of that form, its projecting motion is typically to be produced by the top rod being arranged in injector or hydraulic cylinder, then by being arranged on the upper and lower liftout plate of dynamic model part and transfer the force to push pedal or push rod, ejector sleeve etc. realizing the release of goods.In order to make male template or male model gripper shoe have enough intensity, typically arranging the constitutional details such as mould foot and support column in dynamic model part, support column is arranged on liftout plate, and mould foot is arranged on liftout plate both sides, to provide liftout plate space;Simultaneously in order to ensure ejecting mechanism reliable in action and proper reset, liftout plate can arrange the guide elements such as return pin, push pedal guide pillar, in addition, upper and lower liftout plate to be installed the mould parts such as stopping pin, spacer pin and trip bolt respectively.
When some molding occasion especially molding massive article or liftout plate are provided with the parts such as taper pin pull bar, liftout plate size must be increased, the pin-and-hole that respectively resets on liftout plate, push pedal pilot hole, stopping pin-and-hole, limit pin hole, trip bolt hole and taper pin tie rod hole etc. otherwise can be caused to interfere, but this strengthens die cost and board tonnage virtually, cause production waste.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of liftout plate, it is possible to solve liftout plate each installing hole interference problem, also can increase mould foot Area of bearing simultaneously, improves and ejects location and eject robust motion.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of liftout plate, it is arranged between Bottom clamp plate and moving platen, liftout plate both sides are provided with mould foot, mould foot is fixed on Bottom clamp plate, described liftout plate includes upper ejector plate and lower liftout plate, upper ejector plate is fixed by trip bolt with lower liftout plate, and upper ejector plate and lower liftout plate are located between moving platen and Bottom clamp plate, the big centre of described upper ejector plate and lower liftout plate two is little, in " I shape ", between two and the centre of upper ejector plate and lower liftout plate, it is provided with chamfered transition;The position of corresponding described upper ejector plate and lower liftout plate side is provided with mould foot, and described mould foot two is little broad in the middle.
The invention has the beneficial effects as follows: the present invention is prevented from each mould element on liftout plate and interferes, increase mould foot Area of bearing, improve and eject location and eject robust motion.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the upper ejector plate of a kind of liftout plate of the present invention;
Fig. 2 is the assembling schematic diagram of shown a kind of liftout plate;
In accompanying drawing, the labelling of each parts is as follows: 1, upper ejector plate;2, lower liftout plate;3, mould foot.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1 and Fig. 2, the embodiment of the present invention includes:
A kind of liftout plate, it is arranged between Bottom clamp plate and moving platen, liftout plate both sides are provided with mould foot, mould foot is fixed on Bottom clamp plate, and described liftout plate includes upper ejector plate 1 and lower liftout plate 2, and upper ejector plate 1 is fixed by trip bolt with lower liftout plate 2, and upper ejector plate 1 and lower liftout plate 2 are located between moving platen and Bottom clamp plate, the big centre of described upper ejector plate 1 and lower liftout plate 2 two is little, in " I shape ", is provided with chamfered transition between two and the centre of upper ejector plate and lower liftout plate;The position of corresponding described upper ejector plate 1 and lower liftout plate 2 side is provided with mould foot 3, and described mould foot 3 two is little broad in the middle.The present invention is prevented from each mould element on liftout plate and interferes, increase mould foot Area of bearing simultaneously, improve and eject location and eject robust motion and the liftout plate improved structure that designs, die cost can be reduced to a certain extent, it is remarkably improved die life simultaneously, it is particularly suited for being provided with on molding massive article or liftout plate the injection occasion of the mould parts such as taper pin pull bar, there is good application prospect and practical significance.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
