Description

Technical Field

[0001] The invention relates to the technical field of molding machines, and in particular to a full-automatic EVA secondary steam heating hot and cold integrated machine. Background Art

[0002] EVA resin is an ethylene-vinyl acetate copolymer, and the general vinyl acetate (VA) content is 5% to 40%. Compared with polyethylene, EVA has introduced vinyl acetate monomer into the molecular chain, which reduces the high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. It is widely used in foaming shoe materials, functional shed films, packaging films, hot melt adhesives, wires and cables, and toys. Generally speaking, the performance of EVA resin mainly depends on the content of vinyl acetate in the molecular chain. For the molding of soles, a molding machine is required. First, the existing foaming hot and cold molding machines generally require workers to directly push and pull the mold from the press, which is very easy to consume physical strength; secondly, due to the high vulcanization foaming temperature, the foaming hot and cold molding machine is generally not convenient to transfer the mold from the heating area to the cooling area, and there are certain safety hazards.

[0017] A material unloading conveyor belt 50 is provided on the other side of the hot and cold integrated machine, and the material unloading conveyor belt 50 is fixedly installed on the top surface of the base 1.

[0018] The upper cooling plate 8 and the lower cooling plate 17 are provided with cooling water circulation pipes therein, and the lower heating plate 9 and the upper heating plate 20 are provided with steam heating circulation pipes therein.

[0019] The first hydraulic cylinder 6 and the second hydraulic cylinder 11 are connected to external hydraulic station pipelines through conduits respectively.

[0020] The first electric telescopic rod 28 , the second electric telescopic rod 40 , the third electric telescopic rod 44 and the synchronous motor 35 are electrically connected to an external power source through wires, respectively.

[0021] The first gear 26 , the second gear 33 , and the second gear ring 32 have the same diameter.

[0022] Working principle: When the present invention is used, the mold 48 is placed on the feeding plate 47, and then the telescopic end of the second electric telescopic rod 40 is controlled to extend, and the telescopic end of the second electric telescopic rod 40 pushes the feeding plate 47 to enter between the lower heating plate 9 and the upper heating plate 20 through the second vertical plate 41, and then the telescopic end of the third electric telescopic rod 44 is controlled to extend, and when the telescopic end of the third electric telescopic rod 44 is extended, the feeding plate 47 is driven to move downward through the sliding plate 45, and at this time, the mold 48 on the feeding plate 47 drops accordingly, and during the descent of the mold 48, the cross plates 49 on both sides thereof contact the corresponding two supporting plates 30, and the two supporting plates 30 support the mold 48 in the air through the cross plates 49, and at this time, the telescopic end of the second electric telescopic rod 40 is controlled to retract, so that the feeding plate 47 is reset to prepare for the loading of the next mold, and at this time, the telescopic end of the second hydraulic cylinder 11 is controlled to extend, so that the lower heating plate 9 is removed from the mold 48. The mold 48 suspended by the support plate 30 is lifted up from below, and the top surface of the mold 48 is pushed onto the upper heating plate 20. At this time, the mold 48 is clamped between the lower heating plate 9 and the upper heating plate 20, and high-temperature steam circulates in the steam heating circulation pipes in the lower heating plate 9 and the upper heating plate 20. In this way, the lower heating plate 9 and the upper heating plate 20 heat and melt the EVA resin in the mold 48. When the heating and melting work of the mold 48 is completed, the telescopic end of the second hydraulic cylinder 11 is controlled to retract to its original position. At this time, the mold 48 is suspended by the support plate 30 again, and the two synchronous motors 35 are started. When the two synchronous motors 35 are running, they respectively drive the two cylinders 22 to rotate counterclockwise at the same speed through the third gear 36. When the cylinder 22 rotates counterclockwise, it drives the fixed plate 24 to rotate synchronously. When the fixed plate 24 rotates with the cylinder 22, the second gear 33 rotates counterclockwise around the second gear ring 32 (such as Figure 4As shown in the figure), when the second gear 33 rotates counterclockwise, it meshes with the first gear 26 and rotates clockwise. Since the diameters of the first gear 26, the second gear 33 and the second gear ring 32 are the same, when the second gear ring 32 rotates one circle around the first gear 26, it also rotates 360° with the rotation axis 25 as the axis. Therefore, the second gear ring 32 always ensures that the mounting plate 27 is parallel to the horizontal plane during the rotation process, so that the support plate 30 can smoothly support the mold 48 to move. When the cylinder 22 rotates 180°, the second gear ring 32 also rotates 180° with the rotation axis 25 as the axis. At this time, the mold 48 moves to between the upper cooling plate 8 and the lower cooling plate 17. At this time, the two synchronous motors 35 are stopped, and the telescopic end of the first electric telescopic rod 28 is controlled to extend. As the first electric The telescopic end of the telescopic rod 28 is extended, and the mold 48 will be placed on the lower cooling plate 17. At this time, the telescopic end of the first hydraulic cylinder 6 is controlled to extend to clamp the mold 48 between the upper cooling plate 8 and the lower cooling plate 17. Cooling water circulates in the cooling water circulation pipes in the upper cooling plate 8 and the lower cooling plate 17, so that the product in the mold is quickly cooled and formed. Subsequently, the telescopic end of the first hydraulic cylinder 6 is controlled to retract to its original position, and then the telescopic end of the first electric telescopic rod 28 is controlled to retract to its original position, so that the support plate 30 again stably supports the mold 48 through the cross arm plate 49. At this time, the two synchronous motors 35 are continued to run. When the mold 48 moves to the unloading conveyor belt 50, the unloading conveyor belt 50 supports the mold 48 from the bottom of the mold 48 and intercepts the mold 48 on the unloading conveyor belt 50 (such as Figure 5 As shown), the mold 48 finally remains on the unloading conveyor belt 50 and is transported for unloading.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
