Description
Technical Field
[0001] The invention relates to the technical field of cooling and shaping devices, in particular to a cooling and shaping device for EVA products. Background Art
[0002] EVA products have a wide range of uses. It is widely used in the fields of foamed shoe materials, functional shed films, packaging films, hot melt adhesives, wires and cables, and toys. The significance of cooling and shaping EVA products is to ensure the shape stability and quality of the products. Through cooling and shaping, the shape of the EVA product can be kept stable after molding, avoiding deformation or shrinkage, thereby improving the final quality and performance of the product. For example, common circular EVA products need to be quickly cooled and shaped after production and molding to ensure the stability of the shape. However, in the face of the molded ring-shaped EVA products, at this stage, the inner and outer walls of the product cannot be well fitted for cooling. Basically, the cooling process is carried out directly in the molding mold.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] First, place the pallet and the product directly above the lower plate, aligning them between the inner and outer molding components, and then use the inner mold lifting cylinder to push the hexagonal plate downward to move to the inner side of the product, and start the inner mold cylinder. Since the telescopic rod is connected to a set of support frames, it will push the inner mold cylinder itself to drive the inner mold rack to move horizontally, driving the inner mold gear and the inner mold rotating plate to rotate on the outside of the telescopic rod of the inner mold lifting cylinder. The inclined position of the No. 2 guide port opened on the inner side of the inner mold rotating plate will first drive the inner mold connecting shaft connected to the inside, so that the connected groups of inner mold water-passing plates will open outward along the No. 1 slide groove, and the inner mold connecting shaft on the inside will enter the arc position of the No. 2 guide port when the inner mold rotating plate continues to rotate, and the connected groups of inner mold connecting shafts and inner mold water-passing plates will not be pushed by the inner mold rotating plate. At the same time, the inner mold connecting shaft connected to the filling water-passing plate and the No. 1 slide bar , first in the arc position of the No. 1 guide port, and then enter the inclined position of the No. 1 guide port and be driven to expand, so that several groups of filling water-through plates are respectively filled between the several groups of inner mold water-through plates after expansion, presenting a complete annular structure, fitting on the inner wall of the product, avoiding gaps between the expanded groups of filling water-through plates, resulting in poor cooling effect and easy deformation of the product. Similarly, when the inner mold rotating plate is rotated in the opposite direction, the No. 1 guide port will first drive several groups of filling water-through plates, and then the No. 2 guide port will drive several groups of inner mold water-through plates, and the No. 1 guide port The inclined position is set longer than the No. 2 guide port, so the filling water-through plates are closer to the center position during recycling to avoid interference caused by the recycling of several groups of inner mold water-through plates, and then the inner mold joint of the inner mold water pipe is connected to the external cooling water pump, and coolant is added into several groups of inner mold water-through plates and filling water-through plates to quickly cool and shape the inside of the product.
[0016] After the inner molding component is fitted to the inner wall of the product, several groups of outer mold water-through plates on the middle plate are pushed down by two groups of outer mold lifting cylinders to the outer side of the product, the outer mold cylinder is started, and the telescopic rod pushes the outer mold cylinder itself to drive the outer mold rack to move horizontally, driving the outer mold rotating plate arranged in meshing to rotate. At this time, several groups of outer mold guide ports push the connected outer mold connecting shaft to make the No. 3 slide bar slide in the sliding sleeve, and several groups of outer mold water-through plates are close to each other in a circular ring state and fit to the outer wall of the product. The coolant joint on the outer mold water-through pipe is connected to the external cooling water pump, and coolant is added into the inner side of several groups of outer mold water-through plates to achieve the purpose of rapid cooling and molding of the product. In addition, through the characteristics of splicing and forming of the inner molding component and the outer molding component, the outer plate expands and the inner plate comes close during demoulding, so that the demoulding work is effectively carried out.
[0017] After the product is demolded, the outer external shaping component is first raised to a certain height, and then brought together again to present a circular ring structure. At this time, it will cover the outside of the demoulding components on both sides and contact the discs on both sides. When approaching, it pushes the discs, nozzle pipes, and arc strips on both sides to move toward the center along the fixed seat and compress the reset spring. At this time, the two groups of circular shafts correspond to the positions above the triangular openings on both sides, so when the inner shaping component is raised to a certain position, the circular shaft enters the spiral groove partially set on the lower side of the telescopic rod of the inner mold lifting cylinder through the triangular opening. The continuous rise of the two groups of spiral grooves will push the two groups of circular shafts and arc strips to drive the rotating ring to rotate several circles along the slide rail ring. At this time, the nozzle pipe is connected to the external pump body to extract the demoulding agent, and the inner and outer plates are rotated to automatically spray the demoulding agent, which is convenient for the next demoulding work.

The coolant connector on the outer mold water-through pipe 615 is connected to the external cooling water pump, and coolant is added into the inner side of several groups of outer mold water-through plates 67 to achieve the purpose of rapid cooling and shaping of the product 8. In addition, through the characteristics of splicing and forming of the inner molding component 4 and the outer molding component 6, the outer plate expands and the inner plate approaches during demoulding, so that the demoulding work is effectively carried out.
[0039] Working principle: When in use, first place the tray 7 and the product 8 just above the lower plate 1, aligning them between the inner shaping component 4 and the outer shaping component 6, and then push the hexagonal plate 48 downwards to the inner side of the product 8 through the inner mold lifting cylinder 41, and start the inner mold cylinder 416. Since the telescopic rod is connected to a set of support frames 415, the inner mold cylinder 416 itself will be pushed to drive the inner mold rack 417 to move horizontally, driving the inner mold gear 44 and the inner mold rotating plate 45 to rotate on the outer side of the telescopic rod of the inner mold lifting cylinder 41. The inclined position of the No. 2 guide port 47 opened on the inner side of the inner mold rotating plate 45 will first drive the inner mold connecting shaft 412 connected on the inner side, so that the connected After the several groups of inner mold water-passing plates 413 are opened outward along the No. 1 slide groove 49, the inner mold connecting shaft 412 on the inside enters the arc position of the No. 2 guide port 47 when the inner mold rotating plate 45 continues to rotate, and the several groups of connected inner mold connecting shafts 412 and inner mold water-passing plates 413 will not be pushed by the inner mold rotating plate 45. At the same time, the inner mold connecting shaft 412 connected to the filling water-passing plate 414 and the No. 1 slide bar 411 is first at the arc position of the No. 1 guide port 46, and then enters the inclined position of the No. 1 guide port 46 to be driven to expand, so that the several groups of filling water-passing plates 414 are respectively filled between the several groups of inner mold water-passing plates 413 after expansion, presenting a complete annular structure ( Figure 5), fits on the inner wall of the product 8 to avoid gaps between the unfolded groups of filling water-passing plates 414, resulting in poor cooling effect and easy deformation of the product 8. Similarly, when the inner mold rotating plate 45 is rotated in the opposite direction, the No. 1 guide port 46 will first drive several groups of filling water-passing plates 414, and then the No. 2 guide port 47 will drive several groups of inner mold water-passing plates 413. The No. 1 guide port 46 is set at a longer inclined position than the No. 2 guide port 47, so the filling water-passing plate 414 is closer to the center position during recovery to avoid interference caused by the recovery of several groups of inner mold water-passing plates 413. The inner mold joint of the inner mold water pipe 419 is connected to the external cooling water pump to add coolant The inner side of the product 8 is quickly cooled and shaped by entering several groups of inner mold water-passing plates 413 and filling water-passing plates 414; in addition, after the inner shaping component 4 is fitted to the inner wall of the product 8, the two groups of outer mold lifting cylinders 63 push down several groups of outer mold water-passing plates 67 on the middle plate 61 to be sleeved on the outer side of the product 8, and the outer mold cylinder 612 is started. The telescopic rod pushes the outer mold cylinder 612 to drive the outer mold rack 613 to move horizontally, and drives the meshing outer mold rotating plate 68 to rotate. At this time, several groups of outer mold guide ports 69 push the connected outer mold connecting shaft 66, so that the No. 3 slide bar 65 slides in the sliding sleeve 64, and several groups of outer mold water-passing plates 67 are close to each other to present The ring is attached to the outer wall of the product 8, and is connected to the external cooling water pump through the coolant joint on the outer mold water pipe 615. The coolant is added into the inner side of several groups of outer mold water-through plates 67 to achieve the purpose of rapid cooling and shaping of the product 8. In addition, through the characteristics of the splicing and forming of the inner shaping component 4 and the outer shaping component 6, the outer plate expands and the inner plate moves closer during demoulding, so that the demoulding work is effectively carried out. Finally, after the demoulding of the product 8 is completed, the outer shaping component 6 on the outside is first raised to a certain height, and then moved closer again to present a ring structure. At this time, it will cover the outer side of the demoulding components 5 on both sides and contact with the discs 511 on both sides. When moving closer, it pushes the discs 511 on both sides and the nozzle pipe 5 10. The arc strip 55 moves toward the center along the fixed seat 53 to compress the reset spring 58. At this time, the two groups of round shafts 56 correspond to the positions above the triangular openings 43 on both sides. Therefore, when the inner shaping component 4 rises to a certain position, the round shaft 56 enters the spiral groove 42 partially set on the lower side of the telescopic rod of the inner mold lifting cylinder 41 through the triangular opening 43. The continuous rise of the two groups of spiral grooves 42 will push the two groups of round shafts 56 and the arc strip 55 to drive the rotating ring 52 to rotate several circles along the slide ring 51. At this time, the nozzle pipe 510 is connected to the external pump body to extract the demoulding agent, and the inner and outer plates are rotated to automatically spray the demoulding agent, which is convenient for the next demoulding work.
