Abstract

The utility model discloses an ejection mechanism of an injection mold, which is installed on a movable mold of the injection mold. The movable mold comprises a movable mold plate and an ejector plate. The ejection mechanism of the injection mold comprises a straight ejector pin and an inclined ejector pin. One end of the straight ejector pin is movably connected with the inclined ejector pin, and the other end of the straight ejector pin is fixed on the ejector plate. The inclined ejector pin is installed on the movable mold plate, and the inclined angle of the inclined ejector pin is 1° to 6°. The ejection mechanism of the injection mold of the utility model ejects a plastic product formed in the injection mold, and the inclined ejector pin moves horizontally to separate from the product.

Description

Ejection mechanism of injection mold

technical field

The utility model relates to an injection mold, in particular to an ejection mechanism of the injection mold.

Background technique

The demoulding of injection molding products is the last link in the injection molding process, which determines the quality of the final product. It is necessary to reliably eject the product from the mold. At the same time, it must be ensured that it will not interfere with other parts when closing the mold. Return to the original position for the next cycle. Some injection molded products have reinforcing ribs. Due to the shrinkage of the plastic material, the injection products are often stuck on the thimble, so they cannot be demoulded smoothly under the action of the straight thimble of the injection mold.

Utility model content

The purpose of this utility model is to provide an ejection mechanism of an injection mold that can make the injection molded product demould smoothly in view of the deficiencies of the prior art.

The technical solution adopted by the utility model to solve the technical problem is: the ejection mechanism of the injection mold, the ejection mechanism of the injection mold is installed on the movable mold of the injection mold, the movable mold includes a movable template and an ejector plate, the The ejector mechanism of the injection mold includes a straight ejector pin and an inclined ejector pin. One end of the straight ejector pin is movably connected with the inclined ejector pin. The other end of the straight ejector pin is fixed on the ejector plate. The inclined ejector pin is installed on the movable template. °～6°.

One end of the inclined thimble is provided with a groove, and the head of the straight thimble is provided with a T-shaped connecting block, which can slide in the groove.

The inclined angle of the thimble is 1°.

The beneficial effect of the utility model is that: in the ejection mechanism of the injection mold, the straight thimble pushes the slanted thimble upwards in the vertical direction, and the slanted thimble moves horizontally due to the limitation of the movable template structure, so that the slanted thimble can be combined with the The reinforcing ribs inside the injection molded product are detached smoothly, which in turn makes the entire injection molded product demould smoothly.

Detailed ways

The specific implementations and examples of the utility model will be described in further detail below in conjunction with the accompanying drawings. The described specific examples are only used to explain the utility model, and are not intended to limit the specific implementation of the utility model.

Please refer to Fig. 1, the ejection mechanism of the injection mold of the present utility model is installed on the movable mold of the injection mold, and the movable mold includes a movable template 2 and an ejector plate (not shown), and the ejector mechanism of the injection mold includes a The thimble 4 and a slanted thimble 3, one end of the straight thimble 4 is movably connected to the slanted thimble 3, the other end of the straight thimble 4 is fixed on the thimble plate, the slanted thimble 3 is installed on the movable template 2, and the inclined angle of the slanted thimble 3 is 1 °～6°.

Please refer to FIG. 2 , a groove 31 is provided at one end of the slanted ejector pin 3 , and a T-shaped connecting block 41 is provided at the head of the straight ejector pin 4 , and the connecting block 41 can slide in the groove 31 . The straight thimble 4 pushes the slanted thimble 3 upwards in the vertical direction, and the slanted thimble 3 moves horizontally due to the limitation of the movable template structure, so that the slanted thimble can be smoothly separated from the reinforcing ribs inside the injection molded product, thereby making the whole The injection molded product 1 was demolded smoothly. In the case of ensuring that the injection molded product 1 can be demoulded smoothly, the smaller the slope of the slanted ejector pin 3, the better. Therefore, in this embodiment, the slanted ejector pin with a unilateral inclination angle of 1° is preferred.

As mentioned above, the ejector mechanism of the injection mold of the present invention moves horizontally through the slanted ejector pin, so that the slanted ejector pin can be smoothly separated from the reinforcing ribs inside the injection molded product, and then the entire injection molded product can be demoulded smoothly, ensuring the quality of the injection molded product .

The above-mentioned embodiments only illustrate the principles and effects of the present utility model, as well as the partially used embodiments. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, some Deformation and improvement, these all belong to the protection domain of the present utility model.
