[0035] In the initial state, the die 2 and the punch 3 cooperate together, and the EPP particles heated to a softened state are filled into the cavity between the die 2 and the punch 3. After molding, the storage box 7 is initially cooled and molded by conveying cooling water into the second water-cooling chamber 31, and then the sealing block 33 is driven by the moving mechanism 34 to move toward the inside of the punch 3 to open the air outlet 32, and then the punch 3 is driven by the hydraulic telescopic cylinder 4 to move to the right for demolding. At the same time, the air outlet 32 ​​blows cold air toward the inside of the storage box 7 to further cool the storage box 7 and improve the cooling effect of the storage box 7.

[0036] See also Figure 1 , Figure 3 , Figure 6 , Figure 7 and Fig.11 The cooling mechanism 5 includes a hollow frame 51 arranged between the die 2 and the punch 3, and a vertical moving component 52 for driving the hollow frame 51 to move up and down is installed on the gantry 12, and a pushing component 53 is installed on the left side of the hollow frame 51.

[0037] When the punch 3 is separated from the die 2, the up and down moving assembly 52 pushes the hollow frame 51 to move downward to the right side of the die 2. During the subsequent removal of the storage box 7 from the die 2, the hollow frame 51 can be timely blown and cooled from the outside of the storage box 7, further improving the cooling effect of the storage box 7.

[0039] After the storage box 7 is formed, cooling water is supplied to the first water-cooling chamber 21 to perform preliminary cooling and forming on the storage box 7. When the hollow frame 51 moves down to the right side of the die 2, the ejector 221 is pushed to the right by the electric push rod 222, and then the ejector 221 ejects the storage box 7 in the die 2 to the right, thereby demolding the storage box 7.

[0040] See also Figure 1 , Figure 3 , Figure 8 , Fig.10 and Fig.11 The cooling mechanism 2 6 includes a hollow plate 61 arranged on the left side of the hollow frame 51, and a plurality of air outlet holes 3 611 distributed in a matrix are opened on the right side of the hollow plate 61. An up-and-down moving component 2 62 for driving the hollow plate 61 to move up and down is installed on the gantry 12.

[0041] When the storage box 7 is completely moved out from the interior of the die 2, and the distance between the left side of the storage box 7 and the right side of the die 2 is just enough for the hollow plate 61 to move downward, the hollow plate 61 is controlled to move downward quickly for timely cooling, and the hollow plate 61 is pushed downward to the left side of the storage box 7 by the up and down moving component 2 62, so that the air outlet three 611 blows air to cool the left side of the storage box 7, thereby further improving the cooling effect of the storage box 7.

[0042] See also Figure 1 , Figure 4 and Figure 5 The moving mechanism 34 includes a supporting frame 341 fixedly installed in the ventilation cavity, a movable rod 342 is slidably installed on the left side of the supporting frame 341, a supporting plate 343 is fixedly connected to the left end of the movable rod 342, and the left side of the supporting plate 343 is fixedly connected to the corresponding sealing block 33, a driving motor 346 is installed on the right side of the ventilation cavity, a lead screw 347 is fixedly installed on the left side of the output shaft of the driving motor 346, and the lead screw 347 is threadedly connected to the inside of the movable rod 342.

[0044] When the air outlet 32 ​​is to be opened, the lead screw 347 is driven to rotate by the driving motor 346, and the lead screw 347 is used to drive the movable rod 342 and the support plate 343 to move to the right, so that the support plate 343 drives the sealing block 33 on the left side to move to the right, and the air outlet 32 ​​on the left side of the punch 3 is opened. At the same time, the lead screw 347 drives the turntable 348 to rotate, so that the arc-shaped through groove 3481 drives the sliding rod 3441 to move toward the lead screw 347, thereby pulling the movable rod 344 and the support plate 345 to move toward the lead screw 347, and the air outlet 32 ​​on the other side of the punch 3 is opened, so that the air outlet 32 ​​can blow air outward for cooling.

[0045] See also Figure 3 , Figure 6 , Figure 7 , Figure 8 and Fig.11 Limiting blocks 511 are fixedly installed on the front and rear inner walls of the hollow frame 51, and the limiting blocks 511 slide in cooperation with the grooves integrally formed on the front and rear sides of the storage box 7. The inner wall of the hollow frame 51 is evenly provided with two air outlet holes 512 in the circumferential direction.

[0046] When the storage box 7 moves to the right from the inside of the die 2, the limit block 511 is used to guide and limit the storage box 7, so that the storage box 7 can pass through the middle of the hollow frame 51 horizontally and stably, and then the air outlet hole 2 512 blows cold air around the storage box 7, which can perform synchronous and close-range cooling on the surroundings of the storage box 7, further improving the cooling effect of the storage box 7.

[0047] See also Figure 1 , Figure 3 , Figure 6 , Figure 7 and Fig.11The up-and-down moving component 1 52 includes a first rack 521 symmetrically fixedly installed on the top of the hollow frame 51, the first rack 521 is slidably installed up and down on the right side of the gantry 12, and the right side of the gantry 12 is rotatably installed with a first rotating shaft 522 located on the right side of the first rack 521, and a first gear 523 symmetrically distributed front and back is fixedly installed on the first rotating shaft 522, and the first gear 523 is meshed with the corresponding first rack 521.

A guide groove 527 is installed at a position corresponding to the second rack 526 on the supporting frame 1, and the second rack 526 is slidably installed on the guide groove 527 left and right.

[0048] In the initial state, the hollow frame 51 is located above the die 2 and the punch 3. When the hydraulic telescopic cylinder 4 drives the punch 3 to move to the right, the punch 3 drives the second rack 526 to move to the right, and then the second rack 526 drives the second gear 525 and the second shaft 524 to rotate. After that, the second shaft 524 drives the first shaft 522 and the first gear 523 to rotate through the belt. Finally, the first gear 523 drives the first rack 521 to move downward, so that the first rack 521 pushes the hollow frame 51 to move downward, and moves the hollow frame 51 to the right side of the die 2, so that the limit block 511 is aligned with the grooves on the front and rear sides of the storage box 7.

[0052] When the storage box 7 is completely ejected from the concave mold 2, when the interval between the storage box 7 and the concave mold 2 is greater than the thickness of the hollow plate 61, the electric push rod 2 621 pushes the hollow plate 61 downward to move the hollow plate 61 to the left side of the storage box 7. The guide rod 2 622 guides the hollow plate 61 to improve the stability of the movement of the hollow plate 61. Cold air is blown to the left side of the storage box 7 through the air outlet 3 611 to cool it, further improving the cooling of the storage box 7. When the hollow plate 61 is completely moved to the left side of the storage box 7, the third rack 536 is meshed with the third gear 535. At this time, the hollow plate 61 drives the third rack 536 to continue to move downward, and the third rack 536 is used to drive the third gear 535 to rotate counterclockwise. Then the third gear 535 drives the third rotating shaft 532 and the pushing rod 534 to rotate, so that the pushing rod 534 pushes the storage box 7 to move to the right, so that the storage box 7 is automatically dropped and discharged after being moved out of the hollow frame 51.

After the injection molding is completed, cooling water is pumped into the water inlet pipe 81 through an external cold water pipe, and then the water inlet pipe 81 transports cooling water to the first water cooling chamber 21 and the second water cooling chamber 31 respectively, so that the plastic between the female mold 2 and the male mold 3 is initially cooled to form a storage box 7, and the used cooling water is discharged into the cold water recovery pipe through the water outlet pipe 82.

[0058] Step 2: Drive the lead screw 347 and the turntable 348 to rotate by driving the motor 346, and then the lead screw 347 drives the movable rod 1 342 and the support plate 1 343 to move to the right, so that the support plate 1 343 drives the corresponding sealing block 33 to move to the right and retract into the ventilation cavity. At the same time, the turntable 348 drives the sliding rod 3441 to move toward the direction close to the lead screw 347 through the arc-shaped through groove 3481, and then drives the sliding rod 3441 to drive the movable rod 2 344 and the support plate 2 345 to move toward the direction close to the lead screw 347, so that the support plate 2 345 drives the corresponding sealing block 33 to retract into the ventilation cavity, and the air outlet 1 32 is fully opened.

[0059] Step three, drive the punch 3 to move rightward through the hydraulic telescopic cylinder 4 to separate the punch 3 from the storage box 7, and at the same time, convey cold air to the ventilation pipe 92 through the cold air blower 91, and then the ventilation pipe 92 conveys cold air to the ventilation cavity in the punch 3, so that the air outlet 32 ​​blows cold air outward to cool the inner side of the storage box 7.

[0060] Step 4. During the process of the punch 3 moving to the right, the second rack 526 is driven to move to the right by the punch 3, and then the second rack 526 drives the second gear 525 and the second shaft 524 to rotate, and then the second shaft 524 drives the first shaft 522 to rotate through the belt, and then the first shaft 522 drives the first rack 521 to move downward through the first gear 523, and then the first rack 521 pushes the hollow frame 51 downward to the right side of the die 2, so that the limit block 511 is at the same height as the grooves on the front and rear sides of the storage box 7.

[0061] Step 5. Push the ejector pin 221 to move rightward by the electric push rod 1 222 so that the ejector pin 221 pushes the storage box 7 to the right from the die 2. The right end of the storage box 7 enters the hollow frame 51. The limit block 511 is used to guide and limit the storage box 7 so that the storage box 7 can pass horizontally and stably through the middle of the hollow frame 51. At the same time, the ventilation pipe 92 delivers cold air to the hollow frame 51, so that the air outlet hole 2 512 blows cold air around the storage box 7 to cool the surrounding area of ​​the storage box 7.

[0062] Step six, when the ejector pin 221 completely pushes the storage box 7 out of the die 2, and the distance between the left side of the storage box 7 and the right side of the die 2 is just enough for the hollow plate 61 to move downward, the electric push rod 1 222 drives the ejector pin 221 to move to the left and reset, and then the electric push rod 2 621 pushes the hollow plate 61 downward, so that the hollow plate 61 moves down to between the die 2 and the storage box 7, and at the same time, the ventilation pipe 92 conveys cold air to the hollow plate 61, so that the air outlet hole 3 611 blows air to cool the left side of the storage box 7.

[0063] Step seven, when the hollow plate 61 moves down to be flush with the storage box 7, the third rack 536 meshes with the third gear 535, and then the hollow plate 61 continues to move downward. At this time, the third rack 536 drives the third gear 535 to rotate, and then the third gear 535 drives the third rotating shaft 532 and the pushing rod 534 to rotate counterclockwise, so that the pushing rod 534 rotates to the left side of the storage box 7 and continues to push the storage box 7 to move to the right, so that the storage box 7 is separated from the hollow frame 51, and then the storage box 7 falls downward to be discharged.

[0064] Step eight, the hollow plate 61 is driven to move upward and reset by the electric push rod 2 621. During the upward movement of the hollow plate 61, the third rack 536 first drives the third gear 535 to rotate in the opposite direction, and then the third gear 535 drives the third rotating shaft 532 and the pushing rod 534 to rotate in the opposite direction and reset, so that the end of the pushing rod 534 away from the third rotating shaft 532 rotates back to the top of the hollow frame 51, so as to prevent the pushing rod 534 from blocking the upward movement of the hollow plate 61.

[0065] Step nine, push the punch 3 to move leftward through the hydraulic telescopic cylinder 4 to re-match with the die 2. During the movement of the punch 3 to the left, the punch 3 is used to drive the second rack 526 to move leftward, and then the second rack 526 drives the second gear 525 and the second shaft 524 to rotate in the opposite direction. Then, the second shaft 524 drives the first shaft 522 to rotate in the opposite direction through the belt, and the first shaft 522 drives the first rack 521 to move upward through the first gear 523, so that the first rack 521 pulls the hollow frame 51 to move upward and reset.
