Mould Clamping for injection moulding machine
Elaborate design, strength, not easy to deformation, mould their high strength, small volume, flexible operation is simple, is a frequently used in the mold processing an auxiliary fixture.Main effect is made by the operating in the process of processing and using vibration, displacement, so as to ensure the accuracy of the mould and good finish.Mold clamp quality directly affect the machining accuracy and involves the mold product quality, so the mold clamp in play a crucial role in the process of mould manufacturing.Can make the mould is stable, not a subtle move at will.
Clamp using ductile iron casting and become, through special processing to achieve high mechanical properties, to do black surface treatment to achieve the purpose of not born rusty spot.At the same time adding and exposure to embossing machine, to ensure better fixed mold.The last with high strength, good performance of the parts assembled parts.
With plate type mold clamp clamping workpiece is milling machine commonly used a kind of method, especially on the horizontal milling machine, milling with cutter use most.Should be paid attention to when using the plate type mold clamp:
(1) the location of the mold clamp to arrange appropriate, to the best machining center place pressure on the workpiece rigid, the size of the clamping force should be appropriate, or caused by poor rigidity of workpiece deformation.
(2) the machine shim must correctly under the pressure plate, height is the same as the artifacts or slightly higher than the artifacts, otherwise it will reduce the compression effect.
(3) the clamp bolts must be close to the workpiece, and the bolt should be less than the distance to the workpiece to shim distance, so increase the compression force.
(4) the bolt to tighten, or can make the workpiece moving due to pressure is not enough, so that damage to the workpiece, machine tools and cutting tools.
(5) there are a lot of screw hole on the injection molding machine templates, after use for a period of time the situation of the screw hole and smooth silk, usually adopt the method of maintenance is to expand screw holes level, namely choose by large level of thread bottom hole drill hole reaming, and tapping, large level of yan plates and bolts.Generally use more frequently screw hole is prone to damage, take the above method after repair may also appear smooth silk reaming reaming may again.The causes of slide wire screw hole has two kinds: one kind is bolt screw into the effective depth of the screw hole is too shallow, when they exceed the tensile strength of screw thread tension damage;Another possibility is the threads of the bolt and screw holes have flash burr or dirt, scratch when bolt screwing in the screw hole to speed up the thread surface wear, until slowly decreased tensile ability damage.With big head adjusting bolt clamp is adjusting bolt rollover and damage caused by the deformation of the template workbench.
The precursor of "ONGO" was established in 1992. After more than 20 years running, we have formed a professional team with more than 10 years developing and manufacturing experience in high-grade plastic injection machine. We adpot morden development technology and scientific management system to build "ONGO" Z series high-grade plastic injection molding machine FROM 700KN to 30000KN clamping force.
The company is situated in Ningbo Industrial Electomechanical Park, covering an area of more than 60000 square meters with an annual output of some 3000 sets.
"The profession guarantees quality, the technology Creates future". Depending on up-to-date technology, strong productivity, scientific management and customer-oriented concept, the company has been one of the most active enterprises in plastic machine industry in China!
