Description

Bidirectional ejection die

Technical Field

The utility model relates to an injection mold especially relates to a two-way ejecting mould.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. As shown in fig. 1, it is a part of the liner portion of the coffee maker, and for some products, often because of the function of the product itself, it is necessary to design a groove in the a direction of the product 10, etc., and the product 10 needs a mold structure using a bidirectional ejection mechanism. The product demolding main direction B is provided with an inverted oblique direction, a large sliding block is required to be designed in the oblique core pulling direction generally, only after the oblique core pulling is completely separated from the product, the action of the product 10 in the main ejection direction B can be completed until the product is taken out, the mold opening times and the total mold height of a rear mold are required to be increased by the design similar to the method, and the injection molding machine is required to be changed into a larger model.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a two-way ejecting mould of simple, the low in production cost of action.

In order to achieve the above object, the technical solution of the present invention is:

the utility model relates to a bidirectional ejection die, which comprises a fixed die plate, a movable die plate, a shovel machine, an inclined guide post, a slide block, a push block, a connecting rod, an inclined ejection seat and an ejector plate; the shovel machine and the inclined guide post are fixed on the fixed die plate, the inner end of the shovel machine abuts against the outer end of the slide block, the inner end of the slide block extends into the die cavity, the lower part of the inclined guide post movably penetrates through a guide post hole of the slide block, and the slide block is driven to move transversely; the ejector block is movably arranged in the movable mould plate and extends into the cavity, the upper end of the connecting rod is hinged with the ejector block, the lower end of the connecting rod is hinged with the inclined ejector seat, and the inclined ejector seat is connected in the ejector plate in a sliding mode.

The utility model also comprises a guide block; the guide block is fixedly arranged in the movable template, and the middle part of the connecting rod is movably sleeved in the guide block.

The utility model discloses still include a little mold insert, this little mold insert has the round and reverses the mouth, and little mold insert is put in the fixed die plate for movable mold insert and movable sleeve.

After the scheme is adopted, because the utility model discloses a fixed die plate, movable mould board, shovel machine, oblique guide pillar, slider, ejector pad, connecting rod, oblique footstock, thimble board, the utility model discloses a ejector pad makes the product can be along the back-off direction demolding of product under connecting rod, guide block and oblique footstock combined action through the motion of thimble board, with the back-off of product and ejecting merging in same action direction, the thimble also comes ejecting runner along the direction motion of difference simultaneously, so has two ejecting directions. In the traditional structure, the demoulding of the back-off is realized by adding one mould opening and closing action, so that the ejection distance is almost doubled, the height of the mould frame is very high, and the increase of the injection molding machine and the increase of the production period of the product follow. Therefore, the utility model discloses saved the manufacturing of this type of product greatly and the cost of production, the action is simple.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 2 and 3, the utility model relates to a two-way ejecting mould, including fixed die plate 1, movable die plate 2, shovel machine 3, oblique guide pillar 4, slider 5, ejector pad 6, connecting rod 7, oblique footstock 8, thimble board 9, guide block 91, little mold insert 92.

The fixed die plate 1 and the movable die plate 2 are arranged oppositely, the upper ends of the shovel machine 3 and the inclined guide post 4 are fixed on the fixed die plate 1, the inner end of the shovel machine 3 abuts against the outer end of the slide block 5, the inner end of the slide block 5 extends into the die cavity, the lower part of the inclined guide post 4 is movably arranged in a guide post hole of the slide block 5 in a penetrating mode, and the slide block 5 is driven to move transversely; ejector pad 6 movable mounting just be located the below of slider 5 in movable mould board 2 to prevent that slider 5 warp under injection pressure and lead to the product to produce deckle edge, the die cavity is stretched into to the one corner of ejector pad 6, the upper end of connecting rod 7 is articulated with ejector pad 6, the lower extreme of connecting rod 7 is articulated with oblique footstock 8, oblique footstock 8 slips in thimble board 9. The guide block 91 is fixedly arranged in the movable template 2, and the middle part of the connecting rod 7 is movably sleeved in the guide block 91 so as to ensure that the connecting rod 7 can move on a fixed angle.

The small insert 92 is a movable insert and is movably sleeved in the fixed die plate 1, so that a product can be prevented from being stuck to a front die.

The utility model discloses a theory of operation:

the utility model discloses a slider 5 sliding fit reaches the purpose of marcing forward and moving backward through ordinary oblique guide pillar 4 and shovel machine 3 on back template 2. The pushing block 6 is connected to an ejector plate 9 by using a connecting rod 7 and an inclined ejector seat 8. Because the utility model discloses having cancelled the oblique loose core above the 10 direction A (as shown in fig. 1) of product, directly having changed into the oblique ejecting of product 10 above the A direction, having reduced the action of once opening and shutting the mould, corresponding mould size is littleer, can change into the injection molding machine of small size.

As shown in fig. 4 and 5, the working process of the present invention is as follows:

1. normally opening the mold, and withdrawing the slide blocks 5 at the two sides;

2. the ejector plate 9 is ejected out, the ejector block 6 is pushed out through the connecting rod 7, the product 10 is ejected out along the back-off direction, and the flow channel is ejected out along the normal direction;

3. taking out the product 10;

4. the ejector plate 9 retracts and the mold is closed.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
