Abstract

The invention provides a self-locking sliding block device applied to an injection mold. The self-locking sliding block device comprises a linear driving device, wherein a driving shaft of the lineardriving device is fixedly connected with a plug shifting block, the two opposite sides of the plug shifting block are respectively provided with two shifting pieces, the shifting pieces are V-shaped shifting pieces and are provided with opening ends, plugs sleeve the shifting pieces, preset first through holes are formed in the plugs, the shifting pieces are movably inserted into the first throughholes from the open ends of the shifting pieces, two pressing strips are arranged on the two opposite sides of the plug shifting block respectively, self-locking grooves are formed in the inner sidefaces of the pressing strips, the end parts of the plugs are matched with the self-locking grooves in a self-locking mode, and the end part of the plug shifting block is further connected with a product forming mold. Compared with the prior art, the problem that a product counter-acting force is formed by a shovel base can be effectively solved, and meanwhile, the manufacturing cost of the mold isreduced, and the forming period of the mold is shortened.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a self-locking slider device applied to injection molds. Background technique [0002] In the product molding operation of injection molds, some products require a slider mechanism to be demolded. However, because some slider mechanisms usually have a shovel base design, when they act on the product’s demoulding, they will form a reaction force during the injection molding of the product. The situation, thus affecting the demoulding efficiency. In addition, the structure of the shovel base is relatively complicated, and the manufacturing cost of the mold is relatively high, which will also result in a long molding cycle of the mold. Contents of the invention [0003] In view of this, the present invention provides a self-locking slider device applied to injection molds that can effectively solve the problem of product reaction force formed by shovel foundation, reduce mold manuf...
