Sliding block mechanism of die-casting die

Abstract

The invention discloses a sliding block mechanism of a die-casting die. According to the technical scheme, the sliding block mechanism comprises a sliding block, an inclined guide column, limiting blocks and pressing strips; an inclined hole is formed in the sliding block, the inclined guide column penetrates through the inclined hole, and the sliding block is connected between the pressing stripsin a sliding mode; the limiting blocks are arranged between the pressing strips, a spring is arranged between the limiting blocks and the sliding block, and bead shifting mechanisms are arranged on the pressing strips; the bead shifting mechanisms comprise bead sleeves, shifting beads and pressure springs, and the shifting beads and the pressure springs are arranged in the bead sleeves correspondingly; the shifting beads are connected with one ends of the pressure springs, the bead sleeves are arranged on the pressing strips, and bead holes are formed in the two sides of the sliding block; and the bead holes correspond to the shifting beads. When the die is opened, the sliding block is pulled by the spring, so that the sliding block is fixed so as to prevent the condition that due to thefact that the spring loses effect when the die is closed, the sliding block moves to cause the die to be damaged, and in the process that the sliding block moves outwards, the bead shifting mechanismis used for carrying out the limitation, so that the safety coefficient of the sliding block during die closing is improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a slider mechanism of a die-casting mold. Background technique [0002] Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. The mold is mainly composed of the pouring system, the direct contact part of the material, and changes with the plastic and the product. It is the most complex and the most varied in the plastic mold. It requires a temperature adjustment system, molding parts and structural parts. Among them, the pouring system and molding parts are the parts with the highest smoothness and precision of plastic workers. The mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fi...

Problems solved by technology

[0004] Generally, a spring is installed behind the slider when the mold is opened, and the module is pulled by the spring after the mold is opened, but there is a risk of failure of the spring in the later stage of use. Once the spring fails, the slider is prone to slipping, and the mold may be crushed when the mold is closed.
