[0002] The thimble ejection structure of the existing mold uses the piston rod of the hydraulic cylinder to drive the backing plate and the panel to rise, thereby driving the thimble to complete the action of ejecting the product from the cavity. The hydraulic cylinder is controlled by people, and The upward movement is directly completed. When it is ejected, it generally rises to a relatively high height until the product is ejected from the cavity, otherwise the ejection is prone to incomplete ejection, which makes the ejection efficiency low, which in turn causes the entire mold to be ejected. low production efficiency

The invention provides an ejection positioning structure of an ejector pin of a die. The ejection positioning structure allows high ejection efficiency, accurate ejection positioning and conservation of energy to be realized, thereby allowing production efficiency of the whole die to be high. The ejection positioning structure comprises a plate B, a backing plate, a face plate, a base plate and an ejector pin, wherein the backing plate and the face plate are fixedly connected so as to form an integral body, a cavity is left between the plate B and the backing plate at a lower part, the lower part of the ejector pin is fixed in a location cavity formed by the backing plate and the face plate, and a piston rod of a hydraulic cylinder is fixedly connected with a bottom projecting structure of the face plate. The ejection positioning structure is characterized in that two inner sides of a die rack are located in the part of the cavity and respectively provided with connecting blocks, a gasket structure is arranged below the connecting blocks and located above the backing plate, and a distance between a lower end face of the gasket structure and an upper end face of the backing plate is an ejection distance.
Description
technical field [0001] The invention relates to the structural technical field of product molds, in particular to an ejection positioning structure of a mold thimble. Background technique [0002] The thimble ejection structure of the existing mold, which drives the backing plate and the panel to rise through the piston rod of the hydraulic cylinder, thereby driving the thimble to complete the action of ejecting the product from the cavity. Among them, since the hydraulic cylinder is controlled by people, and The upward movement is directly completed. When it is ejected, it generally rises to a relatively high height until the product is ejected from the cavity, otherwise the ejection is prone to incomplete ejection, which makes the ejection efficiency low, which in turn causes the entire mold to be ejected. The production efficiency is low. Contents of the invention [0003] The invention provides an ejection posit...
