Description
Technical field
The utility model relates to a kind of press, especially a kind of thin-walled mould press of high balance.
Background technology
In the forming process of plastics, all can use mould, this mould often needs the pressing positioner by adapting to position and fix.More particularly, general pressing positioner comprises solid plate and is located at the moving platen of top of solid plate, and in the course of the work, first mould is positioned on solid plate, then carries out pressing by moving platen and fix.When moving platen is pressed together on mould, the power that mould bears is except the pressure of cylinder, also has the gravity of moving platen, namely its total pressure received is very large, and for some thin-walled moulds, this pressure is enough to make die deformation, therefore the positioner of this structure exists poor reliability and the not strong shortcoming of practicality.Whether and present press is in the process of plastic shaping, if be vented bad, blank just there will be dislocation and displacement, and some present mould press also using some blank locator, but cost higher position is that life-span of using is short.
Utility model content
The purpose of this utility model is the defect in order to solve in prior art existing for die press, provides a kind of high balance and the thin-walled mould press preventing material from misplacing.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of thin-walled mould press of high balance, comprise solid plate and be located at the moving platen above solid plate, described moving platen is connected with shifting formwork cylinder, described shifting formwork cylinder is connected with gas pressure station, described shifting formwork cylinder is located at the top of moving platen, the below of described moving platen is provided with balance cylinder, and the plunger rod of described balance cylinder is connected with moving platen, and the air inlet of described balance cylinder is connected with gas pressure station;
Moving platen is punch, and solid plate is die, and the surface that moving platen is relative with solid plate is provided with the cover half ring pushing down diaphragm of rubber blank, and cover half ring is connected with moving platen by spring, and the corner place between described moving platen and solid plate is provided with stage clip;
Balance cylinder is provided with pressure relief opening, and described pressure relief opening place is provided with pressure limiting valve, and the quantity of balance cylinder is four, and four described balance cylinder correspondences are located on four angles of moving platen.
The thin-walled mould press of above-mentioned a kind of high balance, also comprises shifting formwork magnetic valve, and described shifting formwork magnetic valve is two-position two-way solenoid valve, and its air inlet is connected with gas pressure station, and its blowing mouth and shifting formwork cylinders lead to.
The thin-walled mould press of above-mentioned a kind of high balance, the restoring force of described spring is less than the gravity of cover half ring self.
The beneficial effects of the utility model are: because the below at moving platen is provided with balance cylinder, and the plunger rod of this balance cylinder is connected with moving platen, air inlet is connected with gas pressure station, thus moving platen can be subject to balance cylinder upwards lift power, namely can the gravity of balanced dynamic template.Namely can realize thus when moving platen is pressed together on thin-walled mould, mould only affords institute's applied pressure of shifting formwork cylinder, and mould can be avoided should to be subject to too large pressure and to be out of shape; Cover half ring is connected with moving platen by spring; and the restoring force of spring is less than the gravity of cover half ring self; moving platen is in the process run; cover half ring pushes down plastics blank all the time; effectively prevent the defect that mould causes blank to misplace when being vented, and cover half ring is connected with moving platen by spring, serves the effect of buffering; avoid because the excessive damage causing cover half ring of pressure, greatly enhance the service life of cover half ring.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
For making to do further to understand to the utility model, referring to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of thin-walled mould press of high balance, the moving platen 2 comprising solid plate 1 and be located at above solid plate 1, moving platen 2 is connected with shifting formwork cylinder 3, shifting formwork cylinder 3 is connected with gas pressure station 4, shifting formwork magnetic valve 7 is provided with between shifting formwork cylinder 3 and gas pressure station 4, shifting formwork magnetic valve 7 is two-position two-way solenoid valve, its air inlet a is connected with gas pressure station 4, its blowing mouth c, d is connected with two air inlets of shifting formwork cylinder 3 respectively, its gas outlet b is connected with air, shifting formwork cylinder 3 is located at the top of moving platen 2, the plunger rod of shifting formwork cylinder 3 is connected with moving platen 2.
The below of moving platen 2 is provided with balance cylinder 5, and the quantity of balance cylinder 5 is four, and four balance cylinder 5 correspondences are located on four angles of moving platen 2, and the plunger rod 51 of balance cylinder 5 is connected with moving platen 2, and the air inlet 52 of balance cylinder 5 is connected with gas pressure station 4.The side opening of balance cylinder 5 is provided with pressure relief opening 53, pressure relief opening 53 place is provided with pressure limiting valve 6, when in balance cylinder 5, pressure is excessive, pressure limiting valve 6 is opened, namely the air pressure in balance cylinder 5 is allowed to maintain a fixed value by pressure limiting valve 6, also namely realize the gravity that power of lifting that balance cylinder 5 is applied to moving platen 2 just equals moving platen 2, better can control the dynamics that moving platen 2 is applied to mould thus.
In the course of the work, the air pressure in balance cylinder 5, maintains a fixed value, just equals the gravity of moving platen 2 with the power of lifting making balance cylinder 5 be applied to moving platen 2 the utility model under the regulating action of pressure limiting valve 6.Meanwhile, controlled the aeration status of shifting formwork cylinder 3 by shifting formwork magnetic valve 7, realize die sinking and die closing operation.
