Abstract
The invention relates to a mechanical internal-core-pulling mould including a lower push plate, a lower push-rod fixing plate, an upper push plate and an upper push-rod fixing plate, the lower push-rod fixing plate, the upper push plate and the upper push-rod fixing plate are sequentially arranged on the lower push plate, limit connection rods are arranged at the positions of the four vertex angles of the lower push plate, the lower push-rod fixing plate, the upper push plate and the upper push-rod fixing plate, a pad plate and a move mould plate are sequentially arranged above the upper push-rod fixing plate, the four vertex angles of the pad-plate and the move mould plate are arranged on the limit connection rods, springs are arranged between the pad-plate and the upper push-rod fixing plate, and each limit connection rod is sleeved by one spring, a connecting rod is arranged at the side edge of the move mould plate in a hinged connection mode, the connecting rod is vertically arranged, the upper end of the connecting rod is provided with a slant slide rail, the lower end of the connecting rod passes through the pad plate and penetrates into an installing hole of the upper push-rod fixing plate, an internal pulling core is arranged on the slide rail of the upper end of the connecting rod, and the internal pulling core is provided with a slant dovetail groove matched with the slide rail. According to the mechanical internal-core-pulling mould, the internal pulling core having the slant dovetail groove is connected to the connecting rod having the slant slide rail, and mechanical power is transmitted by the mechanical structure to realize core pulling.
Description
Technical field
The invention belongs to the injection mold technical field, particularly relate to a kind of mechanical type interior core pulling mould.
Background technology
There is the moulding on the inclined-plane (as shown in Figure 1) of muscle and back-off in the back-off district in moulding, on mould, needing to do internal core-pulling mechanism solves product and goes out modulus problem, in prior art, loose core the general oil cylinder that adopts as power, but use the words of loose core of oil cylinder, its in-oil cylinder hydraulic oil is easy to splash the die shaping area when mold attaching/detaching, maintenance, owing to after formed product, needing the processing of aluminizing, the surface finish of die shaping area is to minute surface, remove like this hydraulic oil difficulty, in a single day the shaping area surface has hydraulic oil residual, can cause so aluminizing bad.Therefore this mould does not allow to adopt loose core of oil cylinder.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of mechanical type interior core pulling mould, adopts frame for movement to transmit machine power and realizes loosing core.
the technical solution adopted for the present invention to solve the technical problems is: a kind of mechanical type interior core pulling mould is provided, comprise lower push pedal, the lower push-rod fixed head, upper push pedal and upper push-rod fixed head, in described lower push pedal, the lower push-rod fixed head is installed successively, upper push pedal and upper push-rod fixed head, described lower push pedal, the lower push-rod fixed head, spacing connecting rod is equipped with at four drift angle places of upper push pedal and upper push-rod fixed head, described upper push-rod fixed head top is equipped with backing plate and moving platen successively, four drift angles of described backing plate and moving platen are arranged on spacing connecting rod, between described backing plate and upper push-rod fixed head, spring is housed, described spring housing is on spacing connecting rod, described moving platen side is with chain connection mode load bar, described connecting rod is vertically arranged, described small end becomes the slide rail of swallow-tail form with the cross section that tilts, lower end is passed in the installing hole that backing plate penetrates the upper push-rod fixed head, on described small end slide rail, inner core pulling is housed, on described inner core pulling with the dovetail groove that tilts, described dovetail groove and slide rail match.
Described lower push pedal, lower push-rod fixed head, upper push pedal and upper push-rod fixed head one side are equipped with the spacing typing mechanism.
Between described lower push-rod fixed head and upper push pedal, damping pin is housed.
