When moving, the lower die surface 331 can enter the molding cylinder 31 from the lower opening 312 of the molding cylinder 31. During the process, the guide plate 3121 around the lower opening 312 guides the lower die surface 331 to accurately enter the lower opening 312. Internal role

Referring to FIGS. 5 and 9, the intermediate cylinder mold body 34 is composed of a plurality of hollow cylinder molds 341 whose axis is commonly connected to a gas chamber 342 which is in communication with a vent tube 343. Then, it is connected to an air pumping machine (not shown), and the air chamber 342 is driven by an intermediate pushing member 344 (for example, a hydraulic cylinder shaft) to move, and the driving mold 341 is driven to perform a common moving motion; The cylindrical mold 341 has a plurality of fine vent holes 3411 arranged on the circumferential surface thereof; when the cylinder mold 341 is pushed for common movement due to the design choice of size, each of the cylinder molds 341 is linearly moved on the same plane.

The mattress molding apparatus 3 is used to manufacture the manufacturing method of the mattress 2, and the following steps are carried out:

Step 1 : Referring to FIG. 10 , firstly, the upper pushing member 325 is activated to drive the upper mold body 32 downward from the upper opening 311 of the molding cylinder 31 into the forming cylinder 31 to make the upper mold body 32 upper. When the die surface 321 reaches an upper first stop line L1 (ie, a set stop position), the stop action is performed, and the upper first stop line L1 is located above the feed port 316 to avoid blocking or obstructing the inlet port 316. During the feeding operation, the lower driving body 335 is simultaneously driven to drive the lower molding body 33 upward from the lower opening 312 of the molding cylinder 31 into the molding cylinder 31, so that the lower molding surface 331 of the lower molding body 33 reaches The operation is stopped at the first stop line L2 (ie, a set stop position), and the lower first stop line L2 is located above the lower opening 312 for shielding the lower opening 312; If the center line L3 of the front cylinder hole 314 and the rear cylinder hole 315 is used as a calculation reference, the distance A between the upper first stop line L1 and the center line L3 is greater than the lower first stop line L2 and the The distance B between the center lines L3 is approximately equal to the height of the inlet port 316;

Step 2: Referring to FIG. 10, when the upper mold body 32 reaches the upper first stop line L1 and stops, and the lower mold body 33 reaches the lower first stop line L2, the operation is stopped; The inhalation action of the phantom 33, that is, the ventilator (not shown) that initiates the communication of the vent tube 334 generates suction. For example, the air in the forming cylinder 31 is sucked into the air chamber space 333 from the vent hole 332, and then reaches the ventilator (not shown) through the vent tube 334 to discharge outward; In the feeding operation, a feeder (not shown) connected by the inlet pipe 3161 sucks another fiber raw material (ie, a source) from the inlet pipe 3161 through the inlet port 316 to form the molding. The inside of the cylinder 31 is stacked downward on the bottom layer. At this time, due to the suction function of the lower mold body 33, the fiber raw materials sucked into the molding cylinder 31 are stacked downward, and do not fly upward; The feeding amount of one feeding action is stopped when about 50% of a mattress is formed. As can be seen from Fig. 10, the height of the raw material after the first feeding operation is about at the center line L3. The amount of feed or the height of the stack does not have to be very precise, as long as the amount of feed is set at approximately 50%.

Step 3: Referring to FIG. 11 , the intermediate pushing member 344 is activated to drive the air chamber 342 to interlock with the barrel holes 341 of the intermediate tube mold body 34 from the front tube holes 314 of the front side of the molding tube 31. For each corresponding protruding hole and reaching the rear side, each of the rear cylinder holes 315 protrudes a small distance to stop the action, and the suction function of the lower mold body 33 is still continued in the process; then, The second feeding operation is started, and the suctioned fiber raw material is again sent from the feeding pipe 3161 to the inside of the forming cylinder 31 through the inlet port 316, so as to be stacked downward on the original 50% fiber raw material to achieve the feeding 100. The degree of % can be seen from Fig. 10, the height of the raw material after the completion of the second feeding operation is about below the inlet port 316, at which time the overall fiber raw material is in a bulky state, that is, the volume is large and the density is small.

Step 4: Referring to FIG. 12, the suction function of the lower mold body 33 is stopped, and the upper pusher 325 is activated to lower the upper mold body 32 to reach an upper second stop line L4 (ie, one). The stop position is set to stop, and the upper second stop line L4 is located below the inlet 316 for shielding the inlet 1316; also, the second stop line is also mentioned The distance C between the L4 and the center line L3 is preferably equal to the distance between the lower first stop line L2 and the center line L3, that is, A>B, B=C is suitable;

Step 5: Referring to FIG. 12, the air pump (not shown) connected to the vent pipe 324 of the upper mold body 32 receives hot air to form a pressure into the air space 323. The vent hole 322 is sprayed downward into the fiber material to heat the fiber material from above to heat the paste; and at the same time, the air pump of the lower mold body 33 is connected to the air pump (not shown) The hot air is also input to form a pressure into the air space 333, and then sprayed upward into each of the fiber materials through the vent holes 332 for heating and bonding the fiber raw materials from the bottom upward; The

phantoms

32 and 33 are both heated to heat the fiber raw material, and the air pump (not shown) connected to the vent pipe 343 of the intermediate cylinder phantom 34 is activated to generate suction, and the drum mold 341 is sucked. The air inside is into the air chamber 342, and then reaches the air pump (not shown) through the air tube 343, and is discharged outward, so that hot air is input to the upper and

lower mold bodies

32, 33, and the middle When the air is discharged from the cylinder mold body 34, the hot gas airflow is circulated, so that the fiber raw materials in the molding cylinder 31 are sufficiently and uniformly heated, and the conditions such as heating intensity and heating time can be set and adjusted as needed. For example, the heating intensity may be 200 ° C ± 30 ° C, and the heating time may be 10 to 20 min, but the heating adjustments may be adjusted and changed; when the set heating time is reached, the upper and

lower mold bodies

32, 33 stop inputting. Hot air, the intermediate cylinder phantom 34 also stops sucking air, so that the air circulation is stopped;

Step 6: Referring to FIG. 13 , the upper pushing member 325 is activated to drive the upper mold body 32 to press (compress) the fiber material downward for a set time, and the lower pushing member 335 is also activated to drive the lower portion. The phantom 33 presses (compresses) the fiber raw material upward for a set time, because the fiber raw material is in a state of being heated and heated, so that when the upper and lower dies 32, 33 are pressed from the top to the bottom, all The fiber raw materials are collectively pasted together and presented as a square individual, which makes the overall volume shrink and the density becomes larger. It must be mentioned that the volume of the square individual is the size of the mattress that is expected to be formed; It is to be noted that, since the respective barrel molds 341 in which the intermediate cylinder mold body 34 is coated in the fiber raw material are present, the inside of the square-shaped individual after the hot press forming is covered with the drum mold 341, and thus the cylinder mold 341 is also provided. The longitudinal upper and lower portions are the strength-enhancing portions because the longitudinal upper and lower portions of the tubular mold 341 are co-extruded by the upper and

lower mold bodies

32, 33 and the drum mold 341, so that the fiber raw material is formed. More concentrated, denser state Enhance the strength of the joint portion;

Step 7: In the same state as shown in FIG. 13, then, the air pump that is connected to the vent pipe 343 that starts the intermediate cylinder mold body 34 generates a blowing effect, and sends outside cold air into the air chamber 342. The vent holes 3411 of the drum mold 341 are discharged to cool the block-shaped individual to accelerate the setting, and the air cooling time can be set and adjusted; at the same time, the upper and lower molds are simultaneously activated. The inhalation action of the

bodies

32, 33, that is, the ventilator that is connected to the

vent pipes

324, 334, generates a suction effect, and sucks the hot gas contained in the block-shaped individual and the gas fed from the die 341. The gas enters the

plenum spaces

323, 333 along the vent holes 322, 332, and then exits the ventilator through the

vent pipes

324, 334 to discharge outward to form a circulation of air to help the block-shaped individual to lower the temperature. To achieve rapid shaping, the inhalation time of the upper and

lower mold bodies

32, 33 can be set and adjusted; The air blowing action of the drum mold 341 and the suction function of the upper and

lower mold bodies

32, 33 are stopped as soon as the time is reached, and the block-shaped individual is cooled and shaped;

Step 8: Please refer to FIG. 14 , and then start the upper pushing member 325 to drive the upper mold body 32 upward to stop at the upper first stop line L1 to wait for the next stroke; meanwhile, start the intermediate push The piece 344 drives the air chamber 342 to interlock the barrel molds 341 of the intermediate cylinder mold body 34 along each of the rear cylinder holes 315, the block-shaped individual body and each of the front cylinder holes 31 to be withdrawn, to wait for the next stroke; The lower mold body 33 still holds the square-shaped individual upwards. It must be mentioned that, at this time, the square-shaped individual has become the mattress 2 expected to be formed because the mold 341 has not been covered. The cylindrical hole formed (left) after the lateral detachment of each of the drum molds 341 is the elastic cylinder 21 of the mattress 2;

Step 9: Referring to FIG. 15, then, the lower pushing member 335 is activated to drive the lower mold body 33 to hold the mattress 2 downward to move the mattress 2 out of the lower opening 312 of the molding cylinder 31. Externally stopped; at this time, a pushing member 41 may be preset on one side of the bottom edge of the forming cylinder 31, and a carrying platform 42 is preset on the other side;

Step 10: Referring to FIG. 16, finally, the pushing member 41 is activated to push the mattress 2 to move laterally to the carrying platform 42, and the carrying platform 42 can be a conveying table, so that the mattress 2 can be transported to another place. Subsequent processing (for example, inspection, packaging) work, or subsequent processing work can be directly performed on the carrying platform 42.

It is obvious from the above description that the mattress 2 is manufactured by the mattress molding apparatus 3 according to the steps of the above manufacturing method. Referring to FIG. 2-4, the mattress 2 manufactured by the present invention is the largest. It is a special feature that the mattress 2 has a plurality of directly penetrating elastic cylinders 21 in the lateral direction, and the elastic cylinder 21 can be produced because the mattress molding apparatus 3 includes an intermediate cylinder mold body 34 having a majority The drum mold 341 can be inserted into the fiber raw material at the time of feeding, and after the upper and lower mold clamping is performed, the fiber raw material is hot-pressed, and the cylindrical mold 341 is coated in the inside of the square-shaped individual after hot press forming. And after the mold is opened, the cylinder mold 341 is withdrawn from the square-shaped individual, so that the elastic cylinder 21 is exposed; in the present invention, since the fiber material is coated with the drum mold 341 (forming a space), the hot-press molding is collectively accepted. Therefore, the longitudinally upper and lower positions of the formed block-shaped individual corresponding to the position of the die 341 are the strength-enhancing portions (the reason has been mentioned before), so the mattress 2 of the present invention is as shown in FIG. There is a strong part 23 on the upper and lower sides of 21, which can be Lay person produces a better supporting effect.
