Background
In order to meet these requirements, the structure of a conventional injection molding machine is roughly as follows, including: the structure frame consists of a fixed template, a movable template, a rear template and a guide post, and a power cylinder for transmitting motion and locking force; the guide post in the structure frame is arranged between the fixed die plate and the rear die plate, the movable die plate is sleeved on the guide post and can slide along the guide post, the power cylinder body is fixed on the rear die plate or the fixed die plate, the plunger or the piston rod of the power cylinder is connected with the movable die plate, and the movable die plate is driven to open and close the die and lock the die through the action of the power cylinder. The disadvantages of this structure are: firstly, the structural frame is unreasonable in arrangement, the sections of the adopted guide posts are all cylindrical, the friction between the movable template and the guide posts is sliding friction, the motion resistance is increased, parts are easy to wear, and the precision of mold closing is further influenced by the uneven wear and unadjustable structure of the four guide posts; the guide post, the fixed die plate and the rear die plate are connected into a rigid structure, the rack is fixed on a base of the injection molding machine, and the guide post not only guides but also bears locking force, so that deformation generated after stress cannot be compensated, and the precision of model closing is also influenced; secondly, the power cylinder has dual functions of fast moving and clamping, has fast action and slow action, has to be additionally provided with the booster cylinder, and the plunger or the piston rod of the booster cylinder follows up when the movable mould plate is opened and closed, so that the whole system becomes very complicated, the difficulty in control is increased, the parts of equipment are increased, the volume of an oil tank is increased, the movement load is increased, the integral cost is increased, the energy consumption is high, and the working benefit is low.
In order to solve the problems of the clamping mechanism of the traditional injection molding machine, a rapid clamping mechanism appears, for example, the clamping mechanism of the precise injection molding machine with Chinese patent publication No. CN103286928B comprises: the mould locking device comprises a structural frame, a quick moving mechanism of a movable mould plate and a mould locking oil cylinder mechanism, wherein the structural frame consists of a fixed mould plate, the movable mould plate, a rear mould plate and a guide pillar; the cross section of the guide post of the structural frame is rectangular, and rollers are arranged at four corners of the movable template on the upper/lower cylindrical surfaces of the guide post and the inner side surface of the guide post; the movable mould plate fast moving mechanism consists of a motor reduction box, a pair of gears and racks which are meshed with each other and a guide wheel, and the mould locking oil cylinder mechanism consists of four oil cylinders, a mould locking supporting plate and a transmission mechanism, and a through hole for a piston rod of the oil cylinder to penetrate through is arranged on the rear mould plate. The movable template enters a closed position of the movable template and the fixed template quickly by starting the movable template quick moving mechanism, then a transmission mechanism of the mold locking supporting plate is started to drive the mold locking supporting plate to rotate until cross-shaped fingers of the mold locking supporting plate completely cover through holes of a piston rod of an oil supply cylinder of the rear template and stop rotating, then an oil cylinder of the mold locking oil cylinder mechanism is started, the piston rod of the oil cylinder extends outwards until the piston rod of the oil cylinder is contacted with the mold locking supporting plate, and the movable template and the fixed template are completely closed under the driving of the mold locking oil cylinder to wait for injection molding. Therefore, after the movable mold and the fixed mold are assembled, the rotary supporting template is used as a supporting surface of the mold locking oil cylinder, and the movable mold is propped against the pressure of the mold locking oil cylinder to realize mold locking; the mold locking mechanism is high in required precision, and if the telescopic rod of the mold locking oil cylinder does not completely avoid the mold locking support plate, the mold locking support plate can collide with the telescopic rod of the oil cylinder after rotating; in addition, in order to shorten the stroke of the mold locking oil cylinder, when the movable mold closes the mold, the mold locking oil cylinder needs to move to enable the telescopic rod of the mold locking oil cylinder to extend, the more the telescopic rod extends, the larger the energy consumption is, and the extension amount of the telescopic rod of the mold locking oil cylinder needs to be matched with the movement of the mold locking supporting plate tightly to realize quick mold locking, so that the complexity of a mold locking system is increased.
