Abstract
The utility model provides an ejection positioning structure of ejection pins of a mold. The structure ensures high ejection efficiency and accurate ejection positioning, saves the energy, and further ensures high production efficiency of the whole mold. The structure comprises a B plate, a base plate, a face plate, a bottom plate and the ejection pins, wherein the base plate is connected with the face plate in a fastening manner to form a whole; a cavity is reserved between the B plate and the base plate below the B plate; the lower parts of the ejection pins are fixed with a positioning cavity of the base plate and the face plate; and a piston rod of a hydraulic cylinder is connected with a bottom convex structure of the face plate in a fastening manner. The structure is characterized in that connecting blocks are arranged on the two inner sides, located at the cavity, of mold frames respectively; gasket structures are arranged below the connecting blocks, and located right above the base plate; and a distance between the lower end faces of the gasket structures and the upper end face of the base plate is an ejection distance.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of location structure that ejects of die ejector pin.
Background technology
The center lift-out structure of existing mold, thereby driving backing plate, panel to rise, its piston rod by hydraulic cylinder drive thimble to complete the action from ejecting in die cavity by product, wherein, because hydraulic cylinder is to be controlled by people, and directly complete and move upward, when it ejects, generally all can lifting height higher until guarantee that product ejects from die cavity, otherwise eject the situation about not exclusively ejecting that is prone to, it makes the efficiency that ejects low, and then causes the production efficiency of whole mould low.
Summary of the invention
The utility model provides a kind of location structure that ejects of die ejector pin, and it makes the efficiency that ejects high, and the accurate positioning ejecting, and saves the energy, and then makes the production efficiency of whole mould high.
A kind of die ejector pin eject location structure, its technical scheme is such: it comprises B plate, backing plate, panel, base plate, thimble, described backing plate, panel is fastenedly connected and forms integral body, between described B plate and the backing plate of bottom, leave cavity, described backing plate is fixed in the bottom of described thimble, the positioning chamber of panel, the piston rod of hydraulic cylinder is fastenedly connected the bottom projective structure of described panel, it is characterized in that: two inner sides of die frame are positioned at cavity and are partly respectively arranged with contiguous block, the below of described contiguous block is provided with gasket construction, described gasket construction be positioned at described backing plate directly over, distance between the lower surface of described gasket construction and the upper surface of described backing plate is and ejects distance.
Adopt after structure of the present utility model, because being, the distance between the lower surface of gasket construction and the upper surface of described backing plate ejects distance, the height of its contiguous block need to pass through accurate Calculation, guarantee that thimble completes ejects product in die cavity, and there is not backlash, and because gasket construction is originally as flexible structure, it can not produce and damage backing plate, staff is in ejection process, without worrying route problem, hydraulic cylinder is upwards pushed into process to be obstructed, stop, it makes the efficiency that ejects high, and the accurate positioning ejecting, save the energy, and then make the production efficiency of whole mould high.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises B plate 1, backing plate 2, panel 3, base plate 4, thimble 5, backing plate 2, panel 3 is fastenedly connected and forms integral body, between the backing plate 2 of B plate 1 and bottom, leave cavity 6, backing plate 2 is fixed in the bottom of thimble 5, the positioning chamber of panel 3, the piston rod 8 of hydraulic cylinder 7 is fastenedly connected the bottom projective structure of panel 3, two inner sides of die frame 9 are positioned at cavity and are partly respectively arranged with contiguous block 10, the below of contiguous block 10 is provided with gasket construction 11, gasket construction 11 be positioned at backing plate 2 directly over, distance between the upper surface of the lower surface of gasket construction 11 and backing plate 2 is and ejects distance.
