Abstract

The invention discloses an automatic ejection die used for forming a dust shield. The automatic ejection die includes an upper die plate, a middle die plate, a lower die plate, a base plate, a die core and a pulling plate, the die core is arranged on the middle die plate, cavities arranged corresponding to the upper die plate, the middle die plate and the lower die plate form a plurality of die cavities, each of the die cavities comprises a plurality of subsidiary die cavities and a casting cavity, each of the subsidiary die cavities is connected with the casting cavity, the casting cavity has a sprue gate, the base plate is positioned below the lower die plate, one surface of the base plate close to the lower die plate is provided with a groove for accommodating the pulling plate, the pulling plate is positioned in the groove, the die core is composed of subsidiary die cores corresponding to the subsidiary die cavities, the die core and the die cavity form a dust shield molding cavity, each of the subsidiary die cores has an ejection rod, one end of the ejection rod depends on the pulling plate, and the other end of the ejection rod depends on the upper die plate and penetrates through the lower die plate. The automatic ejection die has the advantages of high production efficiency, and easy removal of a product molded in the die.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a self-ejecting mold. Background technique [0002] The dust-proof seal of the button on the car, and the seal of the ball joint between the suspension tie rod and the rocker arm require the use of a cap-shaped dust-proof cover. The above-mentioned dust cover is used as a protective part to prevent dust and muddy water from entering the interior of the button and the interior of the suspension joint. Once it fails, it will aggravate the damage of the electronic products inside the button and cause the suspension joint to rust, which will bring hidden dangers to driving safety. This type of dust cover is simple in structure and requires low production cost. In the prior art, when the mold is taken out, a special ejector mechanism is required to eject the product, resulting in low production efficiency and affecting the control of production cost. Contents of the invention [000...
