Embodiment Construction
[0020] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.
[0021] refer to Figure 1 to Figure 5
[0022] A sliding block injection mold that adopts a card-type top sleeve structure to realize secondary ejection, including a movable mold fixed plate 10 and a fixed mold fixed plate 20, and the front and rear sides between the movable mold fixed plate and the fixed mold fixed plate are respectively A wedge 30 with an inclined inner surface is provided, and a pair of sliding blocks 40 that cooperate to form a cavity 41 of a plastic part are arranged between the two wedges. Inserts are arranged in the sliding block, and the inner wall of the cavity of the plastic part Concave-convex parts are provided, and the sliding blocks are slidably matched with corresponding wedges t...

The invention relates to a sliding spliced block injection mold for realizing secondary ejection by using a clamping-type ejecting sleeve. The sliding spliced block injection mold comprises a moving mold fixing plate and a stationary mold fixing plate; each of the front and rear sides between the moving mold fixing plate and the stationary mold fixing plate is provided with a wedge block of which the inner side surface is an inclined surface; a pair of sliding spliced blocks matched to form a plastic part cavity is arranged between the two wedge blocks; each of the sliding spliced blocks is in sliding fit with the corresponding wedge block; a mold core matched with the cavity is arranged between the two sliding spliced blocks; the stationary mold fixing plate is provided with a pouring system; the moving mold fixing plate is provided with a primary ejection mechanism for separating the sliding spliced blocks from a concave-convex part at the outer side of a plastic part and a secondary ejection mechanism for separating the plastic part from the mold core. The mold is not only compact in structure, but also capable of conveniently realizing injection molding of products which are convex and concave on the appearance and are provided with inner holes.
Description
technical field [0001] The invention relates to a sliding block injection mold which adopts a card-type top sleeve structure to realize secondary ejection. Background technique [0002] In actual injection molding production, due to the different shapes of products, when encountering products with convex and concave shapes and inner holes, mold manufacturers often do not know how to deal with them is the best solution. However, the traditional one-time ejection will inevitably damage the product, resulting in a large number of waste products. Aiming at the dilemma that secondary ejection is rarely used in the mold industry in my country, a sliding block injection mold that uses a cassette top sleeve structure to achieve secondary ejection is needed. Contents of the invention [0003] The object of the present invention is to provide a sliding block injection mold that adopts a card-type top sleeve structure to realize secondary ejection, which not only has a compact struc...
