Description

A kind of ejecting mechanism of mould
Technical field
The utility model belongs to technical field of mold, and in particular to a kind of ejecting mechanism of mould.
Background technology
At present, generally according to the corresponding mould of structure design of plastic products, and plastic products are made using injection molding machine.Should Mould and rear mold before mould generally includes, some moulds further include intermediate die, and form the fuse of plastic products internal structure, are closing During mould, predetermined die cavity is formed in mould, during injection, the plastics of liquid are injected into die cavity by appropriate cast gate, after cooling Predetermined plastic products are formed in die cavity, plastic products and mold separation are then made by ejecting mechanism again.Existing demoulding side The modes such as formula generally use hydraulic cylinder, cylinder, that is, after formed product, the driving mechanism such as operation hydraulic cylinder so that its is right Product is ejected, and this mode is time-consuming and laborious, consumes the energy, meanwhile, which is to have an effect moment, is likely to result in slim modeling The deformation of the workpiece of material.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, the utility model provides a kind of ejector of mould Structure, is slowly progressive by the process that workpiece is released, reduces impact of the push rod to workpiece, and easy to operate, saves the energy.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of ejecting mechanism of mould, including punch-pin and be equipped with the matched cavity plate of the punch-pin, the female bottom Cavity, it is characterised in that stent is equipped with the top of the cavity plate, the cradle top center is connected with cam by shaft, Push plate is equipped with below the cam, the push plate bottom is equipped with multiple push rods, and the push rod at the top of the cavity plate by penetrating institute State in cavity, resetting spring is arranged with the push rod, the resetting spring is arranged between the push plate and the cavity plate.
Further, corner location is equipped with guide rod above the punch-pin, and the cavity plate four corners below position, which is equipped with, to hold Receive the guide groove of the guide rod.
Further, the shaft is connected by bearing with the stent.
Further, the one end of the shaft away from the cam through the stent and is connected with turntable, the turntable Marginal position be equipped with handle.
The beneficial effects of the utility model are:
The utility model is equipped with stent above cavity plate, and cam is connected with by shaft in cradle top center, when After cavity plate is separated with punch-pin, grasp handle and rotate turntable, driven by rotary disc shaft rotates, and shaft driving cam rotates, and makes convex Wheel radius of curvature maximum is contacted with push plate, so that push rod moves downward, workpiece is released, and at this time, resetting spring is in pressure Contracting state, continues rotation cam after workpiece is released, and makes to contact with push plate at cam curvature radius minimum, push plate is resetting bullet Moved upwards under the action of spring, resetting spring resets, and push rod resets, since the outer edge of cam is minimum to song by radius of curvature The curve of rate radius maximum consecutive variations successively, thus by cam by push plate be by the process that push rod is released it is slowly progressive, Impact of the push rod to workpiece is reduced, and it is easy to operate, save the energy.
Brief description of the drawings

Fig. 2 is structure diagram when the utility model resets;
Fig. 3 is the utility model cam drive mechanism structure diagram.
In figure:1 is punch-pin;2 be cavity plate;3 be cavity;4 be stent;5 be push plate;6 be push rod;7 be resetting spring;8 are Cam;9 be shaft;10 be guide rod;11 be guide groove;12 be bearing;13 be turntable;14 be handle.
Embodiment
The utility model is further described below in conjunction with attached drawing:
In Fig. 1~3, a kind of ejecting mechanism of mould, including punch-pin 1 and with the matched cavity plate 2 of the punch-pin 1, it is described 2 bottom of cavity plate is equipped with cavity 3, and the top of cavity plate 2 is equipped with stent 4, and 4 top center of stent is connected by shaft 9 There is cam 8, the lower section of cam 8 is equipped with push plate 5, and 5 bottom of push plate is equipped with multiple push rods 6, and the push rod 6 is by the cavity plate 2 top is penetrated in the cavity 3, and resetting spring 7 is arranged with the push rod 6, and the resetting spring 7 is arranged on the push plate 5 Between the cavity plate 2.
In the ejecting mechanism of above-mentioned mould, it should be pointed out that the 2 top corner location of punch-pin is equipped with guide rod 10, the 2 four corners below position of cavity plate is equipped with the guide groove 11 for accommodating the guide rod 10.
In the ejecting mechanism of above-mentioned mould, it should be pointed out that the shaft 9 is connected by bearing 12 and the stent 4 Connect.
In the ejecting mechanism of above-mentioned mould, it should be pointed out that the one end of the shaft 9 away from the cam 8 passes through The stent 4 is simultaneously connected with turntable 13, and the marginal position of the turntable 13 is equipped with handle 14.
The operation principle of the utility model is as follows:
The ejecting mechanism of mould provided by the utility model, when in use, after cavity plate 2 is separated with punch-pin 2, grasps Handle 14 rotates turntable 13, and turntable 13 drives shaft 9 to rotate, and 9 driving cam 8 of shaft rotates, and makes 8 radius of curvature maximum of cam Contact with push plate 5, so that push rod 6 moves downward, workpiece is released, at this time, resetting spring 7 is in compressive state, when by work Part continues rotation cam 8 after releasing, and makes to contact with push plate 5 at 8 radius of curvature of cam minimum, effect of the push plate 5 in resetting spring 7 Lower movement, resetting spring 7 upwards reset, and push rod 6 resets, since the outer edge of cam 8 is minimum to curvature half by radius of curvature The curve of footpath maximum consecutive variations successively, so by push plate 5 being slowly progressive by the process that push rod 6 is released by cam 8, subtracts Small impact of the push rod 6 to workpiece, and it is easy to operate, save the energy.
In conclusion the utility model provides a kind of ejecting mechanism of mould, it is slowly progressive by the process that workpiece is released , impact of the push rod to workpiece is reduced, and it is easy to operate, save the energy.
The utility model is described in detail in above example, but the content is only the preferable reality of the utility model Apply example, it is impossible to be construed as limiting the scope of the utility model.Equalization made according to the scope of application of this utility model Change and improvement etc., should all still belong within the patent covering scope of the utility model.
