Abstract

PURPOSE:To release a molded foam handily and readily by a method wherein a hole corresponding to the specific reference position on a molding die is provided on the plastic molded form and compressed air is blown in through this hole. CONSTITUTION:The reference position C of a die 11 determined by dimensions A and B is preset to the molding die 11. On one hand, on the plastic molded foam 12a of a hole 13 is provided at the position corresponding to said reference position C and compressed air is blown in from the nozzle 14 set at the reference position C as indicated by the arrows to release the foam 12a from the die 11. By said method, in a circle line using several dies with the same outer dimension, releasing operation can be carried out by one nozzle simply and securely regardless of the shape of a molded product when said dimensions A, B are specified.

（て同じくノズル３により行なわれている。Traditionally, plastic mold forms such as soft or semi-hard urethane mold forms have been released.
As shown in Figure 1, the gap 2a between the mold 1+11 and the molded product 2a
A method is used in which compressed air is blown from the nozzle 3 applied to 1IF2a'' between a and the molded product to be lifted out of the mold l. ,
There is also a method of releasing the mold by blowing compressed air between the nozzle 3 and C1 (1921-1'G) through the hole 4 added in the molded product 2b due to the need for silk-stitching. And -hi Nr method ζ? The compressed air is blown into the mold using the nozzle 3 built into the mold, or manually.
(This is also performed by nozzle 3.

た。The conventional top-up method is highly praised for its ease of making the molded product 11! Not only will the structure become complicated and increase the cost, but the nozzle 3
Since the position is determined by aiming at the outer periphery of the IJν type M.2a, a coefficient set of nozzles is required for the circle line production line 2 which produces the molded product 2a of the shape of the number. Also.

こあるため、めはり、俵数組のノズルが必要となる。The compressed air introduction mechanism also becomes complicated. If an operator manually blows compressed air into the nozzle 31, not only is considerable skill required, but the hole 4 in Fig. The seat cover used for the molded product 2b for solution is attached to the line 11 at the bottom of the seat.
This is a hole for fixing to
This hole 4 also has a different position ζ depending on the molded product 2bi.
Because of this, several sets of nozzles are required.
