Problems solved by technology
Existing injection molds usually use an oil cylinder structure to pull the core of the arc-shaped anti-shrinkage water tank. This type of structure takes up a lot of space and is expensive. In addition, the oil cylinder often has problems such as oil leakage, oil cylinder movement, and oil cylinder retreat. Maintenance costs High, high requirements for molds and production machines

An automobile door handle injection mold rotating core pulling mechanism comprises an upper compound plate and a lower compound plate. A runner plate lower is arranged below the upper compound plate.A mold cavity is formed below the runner plate. A mold foot, an upper ejector pin plate, a lower ejector pin plate and an ejector pin are arranged on the lower compound plate. A cushion plate is arranged on the mold foot. A mold core is arranged on the cushion plate. A buckling machine for controlling secondary mold opening is arranged on the outer walls of the cushion plate, the mold core and themold cavity. An automobile door handle is arranged between the mold core and the mold cavity. Arc-shaped shrinkage-prevention water grooves are formed in the automobile door handle. Reinforcing ribsare formed in the shrinkage-prevention water grooves. An installation hole is formed in the mold core. A guide slide block is arranged in the installation hole. Punched holes are formed in the guide slide block. An arc-shaped guide slide groove is formed in the inner wall of each punched hole. A pull block and a rotating core pulling block are arranged in the punched holes. The pull block is connected with a link rod. The pull block is connected with one end of the link rod in a rotating manner through a pin, and the other end of the link rod is connected with the rotating core pulling block in a rotating manner through a pin. Guide blocks are formed in the outer walls of the two sides of the rotating core pulling block and are matched with the guide slide grooves in the inner wall of theguide slide block.
Description
technical field [0001] The invention relates to an injection mold, in particular to a rotary core-pulling mechanism for an injection mold of an automobile door handle. Background technique [0002] Injection molds produce automobile door handle products. Due to the thickness of the product wall, there is a problem of shrinkage. Therefore, an arc-shaped anti-shrinkage groove structure is designed in the automobile door handle, and a reinforcing rib is made in the anti-shrinkage groove to prevent the product from shrinking. Shrinkage occurs. Existing injection molds usually use an oil cylinder structure to pull the core of the arc-shaped anti-shrinkage water tank. This type of structure takes up a lot of space and is expensive. In addition, the oil cylinder often has problems such as oil leakage, oil cylinder movement, and oil cylinder retreat. Maintenance costs High, high requirements for molds and production machines. Contents of the invention [0003] The object of the ...
