Abstract

The invention discloses an injection mold easy to release. The injection mold comprises a bottom mold holder and a top mold holder. A plurality of bottom mold cores and injection sliding blocks with auxiliary mold cores are arranged on the bottom mold holder, top mold cores are arranged on the top mold holder, and a workpiece mold cavity is formed by the bottom mold cores, the top mold cores and the auxiliary mold cores in a spliced mode. Particularly, a guiding groove is formed in each injection sliding block, mold releasing supporting blocks are arranged on the top mold holder, the mold releasing supporting blocks are connected to the interior of the guiding grooves in a penetrating mode, in the mold opening and closing switching process, the injection sliding blocks are driven to slide outwards in an extending mode or slide inwards in a gathering mode with the bottom mold cores as centers, mold releasing centres are arranged on the top mold holder, and the mold releasing centres are driven to be stretched inside the mold cavity. By means of the injection mold, the design of combining the injection sliding blocks with the mold releasing centres is adopted, when the mold is released, the injection sliding blocks perform extending sliding to enable the auxiliary mold cores of the injection sliding blocks to be separated from an injection workpiece, primary mold releasing of the workpiece is conveniently carried out, then the workpiece is pushed out through the mold releasing centres, and mold releasing is completed. The injection production rate and the product pass percent are greatly improved, and meanwhile production cost is reduced.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold with high efficiency and automatic ejection of workpieces. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and obtaining a molded product after cooling and solidifying. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and t...
