Problems solved by technology

[0004] However, the ejection structure of the above-mentioned injection molding machine can only solve the ejection problem of interlocking products. When the bumper is ejected, due to its large mass and adhesion problems, it requires a large ejection force to be able to be demoulded. , so it cannot be solved by this angle ejection structure

Abstract

The invention provides a secondary ejecting mechanism of a bumper. The secondary ejecting mechanism comprises a lower ejecting plate, a groove, a fixing assembly, a rotary ejecting block and a fulcrum shaft, wherein the lower ejecting block is connected to a moving die of an injection molding machine in a contact way; the groove is formed in the moving die of the injection molding machine; the fixing assembly comprises two fixing blocks which are both fixedly arranged in the groove and are respectively located at two opposite sides of the groove; the rotary ejecting block is located between the two fixing blocks, and two ends of the rotary ejecting block are respectively a stressed end facing to a fixed die of the injection molding machine and a force applying end facing to the lower ejecting plate; and the fulcrum shaft is penetrated in the middle section of the rotary ejecting block, and two ends of the fulcrum shaft are respectively arranged on the two fixing blocks. The secondary ejecting mechanism has the beneficial effect that the secondary ejecting mechanism can be arranged on the injection molding machine and can generate an enough ejecting force to help the bumper demold.

Description

technical field [0001] The invention belongs to the technical field of mold design and manufacture, and relates to a secondary ejection mechanism of a bumper. Background technique [0002] A bumper is a typical part produced by an injection molding machine. However, when the current equipment produces a bumper, there will be a problem that it is not easy to demould. [0003] As disclosed in the application number 201020575390.2, the ejection structure of the mold provided by the present invention includes a thimble and an oil cylinder, the thimble and the oil cylinder are connected through the upper top plate and the lower top plate, and the thimble is at an angle to the center line of the mould. . By setting the ejector pin at an angle with the mold opening direction of the mold, and determining the inclination angle of the ejector rod according to the structure of the actual product, the product interlocked with the mold can be ejected and the product can be demolded smoo...
