Abstract

PURPOSE:To obtain the titled parts with desired strength without thickening the whole of a synthetic resin base plate, by a method wherein a reinforcing synthetic resin plate is preliminarily adhered to a part to be especially made thin through molding and a part to which more strength is imparted to a desired degree of said base plate and the resulting composite structure is molded under vacuum. CONSTITUTION:A synthetic resin base plate 12 is placed between a male mold 14 and a female mold 15 for vacuum molding to be molded and, a reinforcing synthetic resin plate 13 is adhered to a part 18 to be especially made thin through molding or a part necessitating strength higher than other parts and both molds are gradually pressed while air is vented from an air vent pore 16 to obtain the objective part.

Description

【発明の詳細な説明】 この発明は真空成形部品の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing vacuum-formed parts.

例えば、冷蔵、Ｆのドアバッグを真空成形すると、両側
の側壁の頂部等が深く絞られるので非常に薄くなり、機
械的強度が低下する。これを避けるために原板全体を厚
くすればよいが、その場合には原板の材料の量が多くな
りコストが高くなる。For example, when a refrigeration F door bag is vacuum formed, the tops of the side walls on both sides are deeply squeezed, making it very thin and reducing its mechanical strength. In order to avoid this, it is possible to make the entire original plate thicker, but in that case, the amount of material for the original plate increases and the cost increases.

を行ない真空成形部品を得ることを目的とする。The present invention takes this point into consideration, and vacuum forming is performed after adhering a reinforcing synthetic resin plate to the synthetic resin base plate in advance in areas that will become particularly thin after molding or in areas where it is desired to add more strength than others. The purpose is to obtain vacuum formed parts.

FIG. 1 is a perspective view of a refrigerator for explaining the present invention. 2 is a refrigerator, 2 is its door, and 3 is a restraining material to prevent bottles from falling. 4 indicates a side wall, and 5 indicates the top of the side wall.

のであった。FIG. 2 shows a cross section taken along the line AA' in FIG. A force is applied to the regulating member 3 of the door bag in the direction of arrow 10 when a bottle is inserted or the door 2 is opened. Top 5 of side wall 4
Since the drawing is deep, it is considerably thinner and weaker in strength than the original thickness, so cracks may occur at the hole 60 portion through which the regulating material 3 is inserted due to force in the direction of arrow 10, resulting in damage. There were many. In order to deal with this, a reinforcing member is attached to the hole 6 after completion of vacuum forming, or it is reinforced by adhering it from the back side with an adhesive. However, this work involved mounting or gluing in a recessed area, resulting in very poor workability.

溶４等によっても同効である。A synthetic resin base plate 12 is positioned between the male mold and the female mold. Next, the reinforcing synthetic resin plate 13 is bonded to the part 18 which becomes particularly thin after the molding is completed, or to a part whose strength is more secure than others. Then, the two molds are gradually brought into pressure contact while removing air from the air vent hole I6. For example, the thickness will be 1/'2 where the area is doubled compared to the part of the song. Therefore, the reinforcing synthetic resin plate 13 is placed in a range that covers that part.
By gluing the parts, it is possible to maintain the same thickness and strength as the other parts. In addition, in Example 1 described in -F, the contact layer of Supplementary 11 Firefly 4 and 13 is not limited to the adhesive.
The same effect can be obtained by melting 4 etc.

Moreover, as a result, it is also possible to omit tasks that are difficult to work with.
