Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a compact mold base with pryable mold positions. Background Art

[0002] An injection mold is a tool used for plastic injection molding, also known as an injection mold, plastic mold or plastic injection mold. It is a complex structure composed of multiple parts and is used to produce plastic products of various shapes on a plastic injection molding machine. An injection mold usually consists of two parts: a mold core and a mold cavity. When the plastic material is heated and injected into the mold under high pressure, the mold core and the mold cavity will be tightly combined, so that the plastic material fills the entire mold cavity and forms the desired product shape. At present, the pressurizing mechanism of the mold can only pressurize the raw materials, and cannot vibrate and compact the raw materials in the mold during the pressurization process, which will result in the compactness of the produced molding blanks not being high enough. Some injection molding raw materials will also produce air bubbles due to insufficient compactness, resulting in the molding blanks failing to meet the standards. To this end, a compact mold blank with a pryable mold position is proposed. Utility Model Content
