Positive pressure molding machine debugging installation steps - Union star packaging machinery

Positive pressure molding machine installation and debugging steps: install the machine of the mold base on the surface, the mould is installed on surface with a clean cloth wipe clean, and spraying rust-proof oil, in help die sierra lever transparent color food grade lubrication oil. Install the upper die mold base on the equipment, do not tighten bolts, with convenient clamping on edge. Drop the help die cut within the mouth of the indentation. Install the machine mold base under the surface, mould of lower die mounting surface with a clean cloth wipe clean, and spraying rust-proof oil, grease on mould plunger. Install the lower die under positive pressure forming machine of mold base, do not tighten bolts. Manually set the lower die car reach the forming position ( The radius of a curve) By adjusting the machine mold base fixed nut ( When the cord with) , machine screw nut on the mold base or inclined board ( Used when fine-tuning) Under the cut sheet, make the distance between the knife edge plane for a third of the sheet thickness used & ndash; 1/5. ( Some can be set in, and parts and mold structure) Manual turning to shear position, make the blade cut into the plate. Bolt: lock up and down mould lower die after upper die first, from the inside out, before and after the diagonal. In order to ensure that all the mold by the force equilibrium, it is recommended to use the torque wrench, according to the appropriate use of screw torque. 。 Correct install cooling water pipe, pipe. For domestic CAM device, open the machine, should be by adjusting the plunger, molding, blowing, send induction switch start and stop position, to determine the action program. Of hydraulic equipment, should first determine the starting position of the induction switch, and then set the length of time used, adjust the action program. To import the thermoforming machine Angle control program, should be set by plunger, molding, blowing, sending pieces and the starting Angle and stop Angle used to determine the action program and the length of time. Positive pressure molding machine program coarse adjustment can be according to normal process control diagram, it is to simulate a lot of practical production and processing program summary, has a certain universality. Generally only fine-tuning, bigger to the mould of the individual to make the necessary adjustments. Adjust the pressure drop depth, barometric pressure molding, sheet width, the width, the width, heating temperature, cooling water flow or velocity, or when the mould temperature control machine, set the temperature of the cooling water. General help plug pressure drop depth ( H） The determination of: help falling depth ( H） = the depth of the molding products ( H1) — 2 - - - - - - - 10毫米( Often take 3 & ndash; 5 mm） Under the lower die blade, mold, and at the bottom of the roof of the vent should keep unobstructed. Under the condition of the equipment without materials, low speed or check these Settings by using the method of dynamic operation point is correct. Feeding trial, fine adjustment machine, mold, process parameters to normal production.
