The utility model is characterized in that an oil cylinder hinges upon a machine frame, the plunger piston of the oil cylinder hinges upon a moving mold, and adjusting equipment is arranged at the back side of the moving mold. A guide supporting mechanism is arranged under the moving mold. The roller of the mechanism is supported on a guide track fixed on the machine frame. A fixed mold plate is fixed on the machine frame, and the mode-locking accuracy and the molded piece quality of the mould mechanism can be ensured with the help of the hinging and adjusting device of the moving mold and the guide supporting mechanism without a guide rod. Due to the matched mold mechanism without the guide rod, a link mechanism and the adjusting mold, the utility model has the advantages of simple structure, low cost of the device fabrication, and high work efficiency of the matched mold mechanism.
Description
The utility model relates to a kind of plastics forming forcing press, particularly a kind of clamping of plastics forming forcing press.
The clamping of existing plastics forming forcing press is to be power with the hydraulic jack; oil cylinder drives template by one group of jointed gear unit; template is to count the guide rod guiding; the advantage of these traditional clampings is that the transmission mechanism power that is designed to is transmitted enlarging function; can adopt the less oil cylinder of size in the equipment; template is led by guide rod, the big locked mode precision of its rigidity height, but there is following point in this clamping:
1, in the clamping kinematic link is set, simultaneously in order to adapt to different die sizes, also must sets up one and adjust template, add the annex of several guide rods and support guide rod, whole clamping structural member quantity is many, and the manufacture process requirement height increases equipment cost;
2, in the clamping guide rod is set, mold attaching/detaching difficulty, the processing cost of increase plastic products;
3, plastics machinery is for enhancing productivity; mostly between two equipment, establish the manipulator of a common extraction plastics products; guide rod in the tradition clamping brings obstacle for the use of manipulator, thereby influences the raising of production efficiency, is unfavorable for the reduction of goods processing cost.
The purpose of this utility model is that a kind of improved plastics machinery clamping will be provided, and it simplifies the structure of clamping, improves efficiency of equipment, and the rigidity and the precision of energy maintaining body locked mode.
The utility model is achieved in that the later hinged structure of the oil cylinder of clamping is connected with frame, can eliminate the lateral load of oil cylinder, improves its condition of work; The plunger top of oil cylinder is established connecting plate, and hinged structure is connected with moving platen before the connecting plate, is designed to new departure that oil cylinder directly drives template; Establish adjusting device on the preceding free bearing before the moving platen rear side in the hinged structure, when being used for regulating moving platen and just installing to the perpendicularity of guide pass or to the depth of parallelism on fixed form plane; A guided bearing mechanism is respectively established in both sides, moving platen below, and the roller wheel bearing of this mechanism is on guide rail, and guide rail is fixed in frame, thereby guarantees steadily moving and locked mode reliably of moving platen; Fixed form is fixedly arranged on frame, and the working face of fixed form is perpendicular to the guide pass of guide rail.
Oil cylinder of the present utility model directly drives stencil design, make clamping that the complicated bar linkage structure spare that bears strong load no longer is set, also the adjustment template can be set no longer simultaneously, there is not guide rod in the new construction yet, in clamping, do not have link component, adjust the member that template and guide rod etc. are large-scale and the accuracy of manufacture is had relatively high expectations, simplified structure not only, and can reduce the manufacturing cost of equipment significantly; Do not have guide rod in the clamping, give the mounting or dismounting mould and extract product to bring great convenience, and can give full play to the function of extracting the product manipulator, the production efficiency of clamping is improved significantly; Be provided with forward and backward hinged structure, perpendicularity adjusting device and guided bearing mechanism in the mechanism, under the condition of no guide rod, locked mode precision that still can assurance mechanism guaranteeing the high-quality of plastic part, and is improved the oil cylinder condition of work.
