Abstract

The utility model discloses a novel ejector plate which is arranged between a movable mould seat plate and a movable template. Mould feet are arranged at the two sides of the ejector plate, respectively, and are fixed on the movable mould seat plate. The novel ejector plate comprises an upper ejector plate and a lower ejector plate which are fixed with each other by fastening screws and are arranged between the movable template and the movable mould seat plate; the upper ejector plate and the lower ejector plate are respectively bigger at the two ends and smaller in the middle part, and are respectively in an 'I' shape; the mould feet are correspondingly arranged at the sides of the upper ejector plate and the lower ejector plate, and are respectively smaller at the two ends and bigger in the middle part. Therefore, the problem of interference among all mounting holes of the ejector plate can be solved, the support area of the mould feet is enlarged, and the stability of ejection location and ejection movement can be improved.

Description

A kind of Novel top ejecting plate

Technical field

The utility model relates to injection mold mechanism field, particularly relates to a kind of Novel top ejecting plate.

Background technology

Injection moulding is under high pressure conditions, plastic melt to be arrived in closed mold cavity with high speed injection, obtains and the on all four plastic products of die profile after cooling and shaping.Due to the moulding shrinkage of plastics, the solidifying material of the plastic part after injection moulding and running gate system need make its break away from moulds by ejecting mechanism.Ejecting mechanism in injection mold generally has the forms such as push pedal release, push rod release, ejector sleeve release, and no matter the release mode of that form, it is released action and is normally produced by the top rod or the hydraulic cylinder that are arranged in injector, then by being arranged on the upper and lower liftout plate of dynamic model part, force transmission is realized to the release of goods to push pedal or push rod, ejector sleeve etc.In order to make male model plate or male model gripper shoe have enough intensity, the constitutional details such as mould pin and support column are generally set in dynamic model part, support column is arranged on liftout plate, and mould pin is arranged on liftout plate both sides, so that liftout plate space to be provided; In order to ensure ejecting mechanism reliable in action and proper reset, the guide elements such as return pin, push pedal guide pillar can be set on liftout plate simultaneously, in addition, mould parts such as stopping pin, spacer pin and trip bolt will be installed respectively on upper and lower liftout plate.

While the parts such as taper pin pull bar being installed on some moulding occasion especially moulding massive article or liftout plate, must increase liftout plate size, otherwise can cause each reset pin-and-hole, push pedal pilot hole on liftout plate, stop pin-and-hole, limit pin hole, trip bolt hole and taper pin tie rod hole etc. and interfere, but this strengthens die cost and board tonnage virtually, cause and produce waste.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of Novel top ejecting plate, can solve the each installing hole interference problem of liftout plate, also can increase mould pin Area of bearing simultaneously, improves and ejects location and eject robust motion.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Novel top ejecting plate is provided, be arranged between Bottom clamp plate and moving platen, liftout plate both sides are provided with mould pin, mould pin is fixed on Bottom clamp plate, described a kind of Novel top ejecting plate comprises upper ejector plate and lower liftout plate, upper ejector plate and lower liftout plate are fixed by trip bolt, and upper ejector plate and lower liftout plate are located between moving platen and Bottom clamp plate, the large centre of described upper ejector plate and lower liftout plate two is little, is " I shape "; The position of corresponding described upper ejector plate and lower liftout plate side is provided with mould pin, and described mould pin two is little broad in the middle.

The beneficial effects of the utility model are: the utility model can prevent that on liftout plate, each mould element is interfered mutually, increase mould pin Area of bearing, improve and eject location and eject robust motion.

Brief description of the drawings

Fig. 1 is the main TV structure schematic diagram of the upper ejector plate of a kind of Novel top ejecting plate of the utility model;

Fig. 2 be shown in a kind of assembling schematic diagram of Novel top ejecting plate;

In accompanying drawing, the mark of each parts is as follows: 1, upper ejector plate; 2, lower liftout plate; 3, mould pin.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:

A kind of Novel top ejecting plate, be arranged between Bottom clamp plate and moving platen, liftout plate both sides are provided with mould pin, mould pin is fixed on Bottom clamp plate, described a kind of Novel top ejecting plate comprises 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, described upper ejector plate 1 and lower liftout plate 2 large centres, two are little, are " I shape "; The position of corresponding described upper ejector plate 1 and lower liftout plate 2 sides is provided with mould pin 3, and described mould pin 3 two are little broad in the middle.The utility model can prevent that on liftout plate, each mould element is interfered mutually, increase mould pin Area of bearing simultaneously, improve and eject location and eject robust motion and the liftout plate that designs improves structure, can reduce to a certain extent die cost, can significantly improve die life simultaneously, the injection moulding occasion that is particularly useful for being provided with on moulding massive article or liftout plate the mould parts such as taper pin pull bar, has good application prospect and practical significance.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.

Claims

1. a Novel top ejecting plate, be arranged between Bottom clamp plate and moving platen, liftout plate both sides are provided with mould pin, mould pin is fixed on Bottom clamp plate, it is characterized in that: described a kind of Novel top ejecting plate comprises upper ejector plate and lower liftout plate, upper ejector plate and lower liftout plate are fixed by trip bolt, and upper ejector plate and lower liftout plate are located between moving platen and Bottom clamp plate, the large centre of described upper ejector plate and lower liftout plate two is little, is " I shape "; The position of corresponding described upper ejector plate and lower liftout plate side is provided with mould pin, and described mould pin two is little broad in the middle.
