Abstract
A kind of pressure return cam-action mechanism, it is by forcing backhaul block (1), driving wedge slide block (2), mount pad (3), wedge slide block (4), spring members (5), V-type guide plate (6), workpiece (7) to form.Described mount pad (3) is provided with V-type guide plate (6), V-type guide plate (6) is provided with the guiding surface of inclination, oriented inclined-plane on described V-type guide plate (6) is provided with the slipping block that inclined-plane shape guide block matches, described wedge slide block (4) is arranged on the part of the upper die of mould, wedge slide block (4) becomes relative sliding with patrix, workpiece (7) is provided with in the front lower ends of patrix and wedge slide block (4), wedge slide block (4) rear end face is provided with the in-line groove of level corresponding to place below the return spring hole of spring members (5).Force the bottom of backhaul block (1) right part with pressure backhaul inclined-plane, pressure backhaul inclined-plane matches to form with driving wedge slide block (2) and forces return mechanism in mould moves up and down.
Description
Technical field
The present invention relates to moulds of industrial equipment, is a kind of pressure return cam-action mechanism.
Background technology
Wedge mechanism on mould is the oblique motion vertical up-or-down movement of mould being changed into certain angle, the processing tasks of certain slope is completed with the oblique motion of this band certain angle, after completing oblique processing tasks, wedge slide block needs to rely on retracting spring to make it get back to origin-location, and spring has certain life-span, there is the risk of damage, if spring catastrophic failure at work, Wedge mechanism just can not get back to origin-location, and the problem damaged with regard to causing workpiece occurs.At present at Making mold circle, after anti-spring failure, the pressure return of Wedge mechanism has two kinds of versions, and one forces backhaul to hook assembly; Another kind forces backhaul guide plate component, and these two kinds of assemblies are arranged on the both sides of wedge slide block, can meet and force wedge slide block to get back to original position function, but it takies space, wedge slide block both sides greatly, and mechanism is relatively large, also affects the intensity of circumferential component simultaneously.In order to overcome the problems referred to above, spy provides following a kind of device to solve the problem.
Summary of the invention
The present invention is to provide a kind of pressure return cam-action mechanism, and it relies on to force backhaul block and fixed block composition to force return mechanism, and guarantee Wedge mechanism can also get back to precalculated position when retracting spring loses efficacy.Described this pressure return cam-action mechanism, at work by the opening and closing movement up and down of wedge, changes the angular movement of backhaul components into, and then completes the pressure backhaul function of wedge.This device is of value to saves wedge lateral space, and structure is simple, is convenient to processing and assembling, is applicable to the various plastic injection moulding mould needing assembling to force return mechanism, die cast metal mould and cold punching die.A kind of pressure return cam-action mechanism, solves and forces backhaul to hook assembly; Force backhaul guide plate component to take space, wedge slide block both sides large, mechanism is relatively large, affects the problem of the intensity of circumferential component simultaneously.After solving spring failure, Wedge mechanism can not return, damages the problem of workpiece.A kind of pressure return cam-action mechanism, it is characterized in that: it comprises wedge slide block (4), mount pad (3), V-type guide plate (6), force backhaul block (1), spring members (5), workpiece (7), drive wedge slide block (2), described mount pad (3) is provided with V-type guide plate (6), V-type guide plate (6) is provided with the guiding surface of inclination, oriented inclined-plane on described V-type guide plate (6) is provided with the slipping block that inclined-plane shape guide block matches, described wedge slide block (4) is arranged on the upper bolster of mould, wedge slide block (4) becomes relative sliding with patrix, workpiece (7) is provided with in the front lower ends of patrix and wedge slide block (4), wedge slide block (4) rear end face is provided with the in-line groove of level corresponding to place below the return spring hole of spring members (5), the structure of the similar E shape of shape of described pressure backhaul block (1), the left part forcing backhaul block (1) is 7 fonts, the top of described 7 fonts is stuck in a word groove, force the bottom of backhaul block (1) right part with pressure backhaul inclined-plane, described pressure backhaul inclined-plane matches to form with driving wedge slide block (2) and forces return mechanism in mould moves up and down process.

Detailed description of the invention:
A kind of pressure return cam-action mechanism as shown in the figure, the described this Wedge mechanism with forcing return facilities, at work by the open and close movement up and down of wedge, change the angular movement of backhaul components into, and then completing the pressure backhaul function of wedge, it has saves wedge lateral space, and structure is simple, be convenient to the feature of process and assemble, be applicable to the various mould needing to force backhaul.The operation principle of this mechanism is: wedge slide block (4) is arranged on upper bolster, be slidably matched with upper bolster, follow press ram to move both vertically, force backhaul block (1) and wedge slide block (4) from initial state (as shown in Figure 2), along with upper bolster moves downward, after V-type guide plate (6) on drive block contacts with wedge slide block (4), due to the effect on inclined-plane, the driving wedge slide block (2) being installed on die shoe moves to predetermined angular orientation, until workpiece (7) completes processing tasks, reach state as shown in Figure 3, backhaul block (1) and wedge slide block (4) is then forced to move upward along with upper bolster, wedge slide block (4) moves upward to predetermined party under the effect of spring members (6), workpiece (7) exits processing space, arrive original state as shown in Figure 2, complete a working cycles.If spring members (5) damages in On The Cycle Working Process, backhaul block (1) is then forced to contact with each other with driving wedge slide block (2), prolong the slip of bevel direction, force workpiece (7) to deactivate region, ensure the safety of other parts.
