Abstract

PURPOSE:To produce a hollow body whose front and back have different compositions, by pushing a resin film onto a female mold, putting another resin film having a different composition from that of the first resin film thereon by a male mold, and molding them while injecting air between them. CONSTITUTION:In female and male molds 1, 2, a sheet 5 is extruded to a position indicated at a line x-x on the side of the female mold, is pushed into the female mold 1 by the male mold 2, and at the same time is sucked to the female mold 1 by vacuum holes 9 in the female mold 1 thereby vacuum forming it. Then the male mold 2 is withdrawn to a prescribed position, another sheet 6 having a different composition from that of the first sheet 5 is extruded by a die as indicated at a line Xa-Xb, and while a pressurized fluid is being blown out, the sheet is pushed into a female cavity 9 by the male mold 2. After the male and female molds are clamped, highly pressurized air is injected between the sheets 5, 6 via an air feeding pin to form them. Thus, a hollow formed item having different compositions on the front and the back can be obtained.

小径穴でシートを吸着、真空成形させる。The purpose of the present invention is to solve these problems, by placing an accumulator directly below the injection device, and by arranging the extrusion types to face each other on the left and right sides of the accumulator, it is possible to inject two different colors or different wall thicknesses. Cast a die directly below this, the above is l or 2
Separately extrude sheets of different thickness and color from one side of the book accumulator into the male and female molds, for example, the first
As shown in the figure, the male and female molds have a set configuration (in 1, the sheet is first pushed out under the X-X line on the female mold side, and the sheet is pushed into the female mold by the movement of the other male mold. At the same time, the male die is moved back to a predetermined position after being sucked into the cavity by the vacuum hole provided in the female die and vacuum-formed, and the male die is further removed from the die as shown in FIG.
X A-line side sheet is brought into contact with the sheet while blowing out pressurized fluid from the male mold, the female mold is advanced towards this and brought into contact with the sheet as shown in Fig. 5, and the male mold is placed on the circumferential surface. The sheet is sucked through the small diameter hole for vacuum suction and vacuum formed.

終成形行程を終らせる。Fig. 1 showing the present invention shows the overall view of the injection device @A and the mold clamping device 1), and one of the sheets 5 coming out of the die B is the shoulder of the female mold 1 of the mold clamping device located directly under the X-X line. Hydraulic lot 3 in part 1a
When the male mold 2 is activated and brought into contact with the seat 5 first, as shown in FIG. While blowing out pressurized fluid (heated air, etc.) from the small diameter hole B as shown by the arrow 2a, it moves while creating an air curtain between it and the sheet 5, and the sheet is placed in the female cavity 9. At the same time, the male mold 2 retreats together with the movable mold 15, during which time another sheet 6 is extruded from the directly above die B onto the male mold 2 surface as shown in FIG. The sheet 6 between the male and female molds is pushed to a predetermined value of 11'C so that the female mold 1 covers the male mold 2, and the male mold cavity 4 A. With a small diameter hole 8 for full suction, there is no vacuum forming like the female mold described above, and at the same time the mold is clamped on the parting line of the male and female molds, and pressurized air is separately provided in the hollow part 13 as shown in Fig. 6. is injected to complete the final molding process.

真空成形行程は数秒と云う短時間に行うことが好゛まし
い。In this case, the molded product in the female mold 1 must not come into contact with the sheet 6 immediately before it in the slightest. This is because the sheet that comes into contact with the mold is immediately cooled and loses its blowability, and the previous vacuum forming process is preferably carried out in a short period of several seconds.

の大きさにもよるが。1. The air curtain does not come into contact with the male die and the sheet during mold clamping, so it stretches well and the contact surface does not become thick. If this fails, the sheets will be welded together and a hollow body will not be formed. Therefore, the size of the hollow part of the molded product depends on the size of the molded product.

During extrusion, a wide sheet is alternately extruded under high pressure toward the lower triangular die, and the lower die is designed so that the sheet width and wall thickness can be adjusted respectively to increase or decrease, and the sheet is supplied between the male and female open molds directly below. At the same time, the female mold side is first moved toward a predetermined position while injecting pressurized fluid toward the sheet, and at the same time, the sheet is once faced toward the cavity of the female mold with the male mold interposed and moved to a predetermined position 1a. At the same time, vacuum forming is completed through the small diameter hole of the female mold cavity, and at the same time, the male mold is retreated to a predetermined position. Meanwhile, the die directly above the sheet is extruded onto the surface of the male mold, and the male mold advances the female mold toward this while blowing pressurized fluid toward the sheet from just before it. While pushing the sheet between the molds to a predetermined position so as to cover it with the female mold, use the small diameter hole for vacuum suction on the entire surface of the male mold cavity to perform vacuum forming, and simultaneously move the male and female molds to the parting line for the main mold. The sheet is tightened to close and integrate both vacuum molded products at the parting line, forming a hollow part between them, and injecting pressurized air with a separately installed pressurized air supply pin to complete the final forming process.
