Description

Technical Field

[0001] The utility model belongs to the technical field of manufacturing and processing technology of home appliances and automobile interior and exterior decoration parts applicable to IML process, and specifically relates to an injection mold for reducing stress lines of injection products. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. Injection molding machine, also known as injection molding machine or injection machine, is also called "beer machine" in many factories, and the products made by injection molding are called "beer parts". It is the main molding equipment that uses precision plastic molding molds to process thermoplastics or thermosetting materials into plastic products of various shapes.

[0003] In vertical injection molding machines, the injection device and the clamping device are arranged vertically. This structure makes the installation and disassembly of the mold more convenient and is suitable for the production of small and medium-sized plastic products. In horizontal injection molding machines, the injection device and the clamping device are arranged horizontally. This structure makes the machine occupy a smaller area and is suitable for the production of large plastic products. The vertical-horizontal compound injection molding machine combines the characteristics of vertical and horizontal, and can produce both small and medium-sized plastic products and large plastic products.

[0004] The existing traditional injection mold structure cannot meet customers' requirements for product stress lines for products with display windows. The injection molded products have serious rainbow lines, which directly affects the end customers' visual experience in the car. When customers watch the central control display screen while wearing sunglasses while driving, the rainbow lines directly affect the covered screen display and make it difficult to see.
