Abstract

The utility model discloses an ejection mechanism capable of completely taking out an injection molding product, which mainly consists of an ejector rod, an oblique ejector rod, a limiting rod, a swing block, an ejector rod fixing plate and an ejector rod base plate; the swing block is hinged on the ejector rod base plate by a hinge pin, the lower part of the ejector rod moveably passes through the ejector rod fixing plate, and the lower end thereof props against a vacant groove of the swing block; the lower part of the limiting rod moveably passes through the ejector rod fixing plate, the lower end thereof props against the upper end face of the swing block, which is provided with a groove, and a stepped head part at the lower end of the limiting rod can fall into the groove in the upperend face of the swing block. In the utility model, after the plastic product is propped out by the ejector rod and the oblique ejector rod, and an upper mould and a lower mould are separated for a certain distance, the limiting rod props against and presses the swing block, the swing block swings around the hinge joint thereof to further push and prop the ejector rod upwards so as to cause the ejector rod to further push and prop the plastic product upwards, thus causing the plastic product to swing around the oblique ejector rod so as to cause the plastic product to be completely separated from the upper end faces of the ejector rod and the oblique ejector rod, or even to automatically fall off.

Description

The ejecting mechanism that injection-molded item can be taken out fully

Technical field

The utility model relates to a kind of mould structure, particularly relates to a kind of ejecting mechanism that injection-molded item can be taken out fully.

Background technology

Plastic injection mould is an instrument of producing plastic products, uses very extensive.Generally all be plastic products and running gate system to be expected to eject with fixed attention after plastic products injection moulding, coagulate material and plastic products by manually from mould, taking out running gate system again by ejecting mechanism.After the ejecting mechanism of commonly using ejected plastic products, running gate system was coagulated material and plastic products usually can be bonded on the ejecting mechanism, can not come off automatically, caused trouble for workman's pickup.

The utility model content

The ejecting mechanism that injection-molded item can be taken out fully that provides a kind of pickup to be more prone to is provided the purpose of this utility model, and this mechanism can make injection-molded item can separate preferably with ejecting mechanism, even comes off automatically.

For achieving the above object, technical solution of the present utility model is:

A kind of ejecting mechanism that injection-molded item can be taken out fully, it mainly is made up of push rod, angle ejector rod, gag lever post, centering block, push rod fixed head, push rod seat board; Described centering block is hinged on the push rod seat board by bearing pin, is provided with short slot in a side of centering block, is provided with groove in centering block opposite side upper surface; The push rod fixed head is passed in the bottom activity of described push rod, and its lower end leans on the short slot of centering block, and die cavity is stretched in the upper surface of push rod; The push rod fixed head is passed in the bottom activity of described gag lever post, and its lower end leans the upper surface that has groove at centering block, and the ladder head of gag lever post lower end can fall in the groove of centering block upper surface; Described angle ejector rod bottom is connected on the push rod fixed head, and die cavity is stretched in the upper surface of angle ejector rod.

After adopting such scheme, because the utility model is after plastic products are ejected by push rod, angle ejector rod, after upper and lower mould separates certain distance, gag lever post roof pressure centering block, centering block are around its pin joint swing, and the ejection push rod further makes progress, impel further ejection plastic products upwards of push rod, make plastic products center on the angle ejector rod swing, thereby plastic products are separated fully with the upper surface of push rod, angle ejector rod, even come off automatically.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is that the utility model does not eject state diagram;

Fig. 2 is that the utility model ejects state diagram;

Fig. 3 state diagram that to be the utility model workpiece separate fully with push rod.

The specific embodiment

As shown in Figure 1, a kind of ejecting mechanism that injection-molded item can be taken out fully of the utility model, it mainly is made up of push rod 1, angle ejector rod 2, gag lever post 3, centering block 4, push rod fixed head 5, push rod seat board 6 and bearing pin 7.

Described centering block 4 is hinged on the push rod seat board 6 by bearing pin 7, is provided with short slot 41 in a side of centering block 4, is provided with groove 42 in centering block 4 opposite side upper surfaces; Push rod fixed head 5 is passed in the bottom activity of described push rod 1, and its lower end leans on the short slot 41 of centering block 4, and die cavity 10 is stretched in the upper surface of push rod 1; Push rod fixed head 5 is passed in the bottom activity of described gag lever post 3, and its lower end leans the upper surface that has groove 42 at centering block 4, and the ladder head of gag lever post 3 lower ends can fall in the groove 42 of centering block 4 upper surfaces when centering block 4 swings.In this structure, push rod 1 and angle ejector rod 2 are fulcrum with centering block 4 pin joints, and roof pressure forms the seesaw structure in the both sides of centering block 4 respectively.

Described angle ejector rod 2 bottoms are connected on the push rod fixed head 5, and die cavity 10 is stretched in the upper surface of angle ejector rod 2.

Operation principle of the present utility model:

1, as shown in Figure 2, upper and lower mould divides mould, after plastic products are ejected by push rod 1, angle ejector rod 2;

2, as shown in Figure 3, after upper die and lower die separate certain distance, gag lever post 3 roof pressure centering blocks 4, make centering block 4 around its pin joint swing, ejection push rod 1 further makes progress, impel push rod 1 further upwards ejection plastic products 20, make plastic products 20 around angle ejector rod 2 swings, thereby plastic products 20 are separated fully with the upper surface of push rod 1, angle ejector rod 2.

Emphasis of the present invention just is: increased a gag lever post and the further centering block of ejection push rod.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
