Fig. 2 a-2c is the zoomed-in view in pinch off zone of the mould of Fig. 1, comprise area surrounded by circle A institute, different phase in finishing processing, but the molded seam of part also is not compressed in Fig. 2 a, seam is extruded so that the welding reinforcing section to be provided in Fig. 2 b, in Fig. 2 c the pinch off parts of upper mold section compressing female die with shear seams on this part and
Fig. 3 is the sectional view that passes the fringe region of half module, has shown an embodiment and its maintenance in half module of pinch off parts in detail.
Detailed description of preferred embodiment
With reference to figure 1, in sectional view, shown the zone of hot forming tool, wherein the combination of two thin plates appears at pinch off zone 1.In the thermoforming processing of two thin plates, it is that tabular is fixed on such as on the bracing frame 2 with parallel that two thin plates begin, by half module 3,4 along the effect of the direction of arrow 5,6 and by at die cavity or at plate or the internal pressure booster action between the two, with two sheet formings and combine.These thermoforming technologies are known in the prior art field, do not become a part of the present invention.
With reference to figure 2a, half module 3,4 lumps together, and stretches and shaping sheet 7,8 meets in the pinch off zone and in the contact of seam 19 places, they pass the pinch off zone of each half module at this up to thin plate.Half module 3,4 comprises respectively the surface 10 and 11 in the complementation in pinch off zone.With reference to figure 2b, half module further lumps together with the thickness to one of the contact area that reduces plate 7 and 8 value less than the combination thickness of undeformed pair of plate.Be extruded reinforcing section 12 in the pinch off region material whereby to form an inside.
Illustrated as accompanying drawing, in the present invention, a half module 4 becomes one with a pinch off zone, and this pinch off zone can be moved along a direction with respect to the other parts of this half module, and this direction is away from the direction of this half module operation.Specifically, pinch off zone 13 is set in place within the passage 14 of half module, and keeps it is remained on usual position by spring 15, this spring 15 is preferably compressed in advance, so that before it is retracted to 14 inside, chamber, must apply a certain size power of opposing parts 13.So, in Fig. 2 b, provided a welding reinforcing section wt although mould enough closely is bonded together to extrude from the pinch off zone with the junction between two thin plates with extruding plastic material in the pinch off zone and with it, pinch off parts 13 also are not subjected to enough big power so that it is withdrawn in the chamber 14.Importantly owing to the resiliency supported of pinch off parts, half module can not be bonded together too quickly, and it will cause enough big dynamic force with mobile pinch off parts.
Selectable parts, spring and passage itself can be easily, and as described below, yet shown structure is simple, and provides self actuating by the proper motion of half module in mold pressing processing.
As mentioned above, have a lot of methods that substitute for the spring that uses compression in advance.If what used this moment is spring, but does not compress in advance, can use enough big spring rate or the resisted movement by separately keeping spring up to the thickness that reaches minimizing.Replacement as spring, can in a hermetic chamber structure, use hydraulic pressure or pneumatic system or have hydraulic pressure or pneumatic actuator, in a single day it can use the automatic pressure relief valve, or uses the minimizing thickness that reaches required just to separate the valve that control mode activates.Similarly, can also and return electrical power for operation or mechanical automatic system on the basis in release.
With reference to figure 2c, the still further fluid-tight engagement of half module.Gap turn narrow when the pinch off zone, the extruding force that material is further squeezed out the chamber increases, when particularly material turns cold in the zone that it contacts with half module.In case what the closure by half module was applied to that power on the parts 13 that are positioned at the pinch off zone surpasses spring 15 compresses the threshold values that is provided with in advance, parts 13 will be withdrawn in the chamber 14 when closed when half module continues.Shown in Fig. 2 c, for the antelabium 16 at the edge in chamber 14 with the overlapping chamber that enters into another half module 3.By this way, the surface 17 of half module 3 and the surface of half module 4 18 are overlapped to have tolerance closely, and edge so separately is with other flange of shear seams zone 19 and thermoforming object.In order to improve the processing edge of thermoforming object, need remove seam by the shear action on surface 17 and 18, so two half modules should have minimum horizontal tolerance to provide the gap of precision maximum between surface 17 and 18.Ideal situation is that this gap does not exist, and in fact requires little gap is arranged so that two-half die not collision between the edge 30 and 31 of two-half die when being bonded together.The requirement attractive in appearance of the material of thermoforming, its character and thickness and shaped article is depended in the maximal clearance at edge, and this maximum gap will provide enough Surface Finishing.When thermoforming was used for the ABS plastic of indoor object, suitable gap was 0.1mm.Can use alignment rods or other similarly to install so that horizontal registration accurately to be provided when two-half die is bonded together, so that when a large amount of the manufacturing, reach little tolerance.
With reference to figure 1 and Fig. 3, pinch off parts 13 bear the power that continues from spring 15, and by the such spring force of holding device opposing to remain in the chamber, described holding device comprises that wherein leg 22 is resisted against on the boss 23 from horizontally extending leg 22 of the lower limb of parts 13 and the boss 23 that is arranged on the passage.By mounting shell body portion 25 when the general assembly, can assemble half module easily by this way.
Be clear that can adopt other method to replace above-mentioned maintenance leg method, they are known to those skilled in the art.For example, the pinch off parts can comprise the hole of two or more groove shapes that extend laterally and pass through and pass these holes and be fixed to pin on the mould, with convenient pin in groove when mobile, the pinch off parts can move up and down, and the mobile pin that is subjected to of pinch off parts is resisted against the restriction that the groove end acts on.This structure only needs the processing of simple rectangular channel to keep the pinch off parts, makes die assembly compact more.
Therefore, the invention provides thermoforming mold pressing equipment with simple structure and actuating, it can either make material in the obviously distortion of pinch off zone, can also carry out shearing effective and attractive in appearance and finishing to the object of moulding, and not use independent cutter or other independently actuated components.The moulding of parts and finishing are finished in a procedure of processing, make parts be convenient to dismounting, inject foam in the time of perhaps still in mould.So exempted manual parts finishing or independent automatic trimmer (having aligning relevant and parts setting operation), and kept the welding reinforcing section simultaneously with it.
Valuable is, can be by the adjustment of compression in advance of spring force and spring being controlled the degree of material deformation.Alternative device can be provided, and parts 13 are forced backward rigidly when reaching required thickness whereby, and under this situation, spring 15 can be in the state of excess compression.Such device can comprise, for example, a plurality of projectioies on the top surface of parts 13 or flange 28, they are resisted against on the surface 10 of another half module, pass or pass substantially by the material of moulding.Projection or flange or analog also can be arranged on the pinch off surface 10 of another half module 3, or on two surfaces 10 and 11.
