Abstract
The utility model relates to a die assembly mechanism for an injection machine. The die assembly mechanism comprises a core plate and a solid plate which are used to be connected with a first semi-die and a second semi-die of a mold, and is characterized in that a rotating disc capable of rotating under the driving action of external force is arranged on the core plate; a plurality of first semi-dies can be simultaneously fixed on the rotating disc; and the rotating disc is positioned between the core plate and the solid plate. Compared with the prior art, the die assembly mechanism has the advantages that a cooling process of a parison can be transferred to the outside of a cavity, so that the cooling time of the parison in the cavity is shortened, a molding cycle is shortened, and the production efficiency is improved. The die assembly mechanism for the injection machine is particularly suitable for molding a thick-wall parison which can be cooled at room temperature.
Description
Technical field
The utility model relates to plastic injection equipment, refers to that specifically a kind of injector uses clamping.
Background technology
Injector has another name called injection (mo(u)lding) machine or injection machine, and it is to utilize mould for plastics to process the main former of the plastic products of different shape thermoplastic or thermosetting material.Injection machine is made up of injecting systems, matched moulds system, Hydraulic Power Transmission System, electric control system, lubricating system, heating and cooling system, safety monitoring system etc. usually.
Wherein, the effect of matched moulds system is the assurance mould closes, opens and eject goods.Simultaneously, after mould closes, supply with the enough clamp forces of mould, get into the cavity pressure that die cavity produces, prevent that mould from cracking, cause the bad quality of goods with the opposing molten plastic.The matched moulds system mainly is made up of clamping, mould adjusting mechanism, ejecting mechanism and safety system.Wherein clamping generally includes moving platen and the solid plate that fixed mould is used, and in the prior art, moving platen and solid plate can only relatively move each other, drives the closed and unlatching of mould.
Melt need could eject goods by opening mold after supercooling after the injecting systems pressurising is expelled in the die cavity of mould.Usually this process required time takies the large percentage of entire product molding cycle, has reduced production efficiency to a certain extent.
Summary of the invention
The utility model technical problem to be solved is the present situation to prior art to be provided a kind of and can effectively reduce the injector that thereby the cooling time spent in mould enhances productivity after the injection mo(u)lding and use clamping.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this injector is used clamping; Comprise and be used for moving platen that is connected with first half module of mould and the solid plate that is connected with second half module of mould; It is characterized in that said moving platen is provided with the revolving part that can under external force drives, rotate; Can fix a plurality of described first half modules simultaneously on this revolving part, and said revolving part is between said moving platen and said solid plate.
Be provided with many pull bars of spacing guiding usefulness between said moving platen and the solid plate, said rotating disk passes the center pull rod in these pull bars and rotates as the center.This structure can increase the steadiness of whole matched moulds system, and moving platen and revolving part are had certain guide effect.Described drive unit can be fluid pressure drive device, also can be electric driver, or can drive the drive unit that rotating shaft is rotated in other prior art.
The structure of said revolving part can have multiple, and preferably, described revolving part can be spacing rotating disk on said center pull rod.
Perhaps, described revolving part can also be to comprise that ring set is at the base on the said center pull rod and a plurality of armed lever that is used for fixing said first half module on this base that is arranged on.
Compared with prior art; The utility model is provided with the rotating disk that can rotate on moving platen, can first half module of mould be fixed on this rotating disk, and can fix a plurality of first half modules; Like this after one first half module and the second half module moulding; Opening mold, the parison after the moulding leaves second half module with moving platen and rotating disk, and parison can continue to be cooled to moulding and ejected on this first half module this moment; Meanwhile, rotating disk rotates under the driving of driving mechanism, be fixed on another first half module and the second half module matched moulds on the rotating disk after, carry out the injection moulding of next product; This clamping can be transferred to the cooling of parison outside the die cavity, has reduced the cool time of parison in die cavity, has shortened molding cycle, has improved production efficiency.The injector that the utility model provided is with the moulding of the especially suitable heavy wall parison that can at room temperature cool off of clamping.
Description of drawings
Fig. 1 and Fig. 2 are the schematic perspective view of the utility model embodiment assembly structure different angles.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this injector comprises with clamping:
Moving platen 1, the rotating disk under it is used to install first half module.
The installation of above-mentioned first half module and second half module can be exchanged as required.
Be provided with between moving platen 1 and the solid plate 2 moving platen 1 is led so that the pull bar 4 of first half module 5 and the accurate matched moulds of second half module, 6 abilities.Pull bar in the present embodiment has three.
Rotating disk 3 is fixed on the below of moving platen 1 towards the surface of solid plate 2, and a plurality of first half modules 5 can be installed on it simultaneously.First half module in the present embodiment has three.Rotating disk 3 passes three center pull rod in the pull bar and is fixed on the center pull rod, serves as that axle rotates with this center pull rod, and under the guide and limit effect of this center pull rod, can make first half module and the accurate matched moulds of second half module on the solid plate on it.
The drive unit (not shown) drives connection rotating disk 3, and this drive unit can be a hydraulic-driven, also can be that the gear train transmission drives, and promptly can adopt any Drive Structure of the prior art or combination.
The example that is shaped to that is used for the plastic bottle parison below with above-mentioned clamping is explained the operation principle of this clamping.
At first be first first half module and the second half module matched moulds that is fixed on the rotating disk; Melt is expelled in the die cavity of mould; Because mould is cold, melt cools off aftershaping a little in die cavity, and this moment can be with opening mold; After parison breaks away from second half module with moving platen, eject after under natural environment, being cooled to fully typing.After first first half module die sinking, dial rotation makes second first half module on the rotating disk aim at the second half module matched moulds, carries out the injection moulding second time.Repeat the action of first first half module after the moulding, then the 3rd first half module and the second half module matched moulds.After the 3rd first half module opened, the parison in first first half module ejected, and first first half module goes back to and the second half module matched moulds.So circulation has reduced the cool time of parison in die cavity, has shortened molding cycle, has improved production efficiency.The moulding of the especially suitable heavy wall parison that can at room temperature cool off.
