Problems solved by technology

On the other hand, in the case of blow molding, it is not necessary to provide a draft in the mold, and in some cases, a molded product that does not have a shape based on the draft of the mold is molded.
In addition, in vacuum forming, the wrinkled lines (wrinkles) on the surface of the molded product disappear due to the formation of the sheet with wrinkled lines (texture), and even if the mold has wrinkled lines (texture), the transferability is poor.

no. 1 approach

[0081] The method of manufacturing the cover, the molded product, and the mold for molding of the first embodiment will be described. Hereinafter, an example in which a telescoping cover is used for a lifting device of a stretcher having a lifting function will be described. In addition, the telescoping cover is not limited to stretchers, and can also be applied to other bed devices with lifting functions such as medical beds, nursing beds, operating tables, and newborn beds, and can also be applied to tables, chairs, etc. Products with lifting function.

[0082] 1.1 Stretcher structure

[0083] First, use figure 1 and figure 2 The overall structure of the stretcher 1 will be described. figure 1 A perspective view of the stretcher 1 is shown. figure 2 It is a diagram showing the raising and lowering operation of the stretcher 1, showing the state in which the middle bed 2 (bed portion) of the stretcher 1 is raised most (hereinafter referred to as "highest position") and...

no. 2 approach

[0170] Next, a second embodiment will be described. In the second embodiment, a description will be given of a case where a shape serving as a guide for a cutter or the like is provided when cutting is performed at the cutting position of the molded product 100 .

[0171] 2.1 Sectional shape of molded product

[0172] use Figure 12 Next, the cross-sectional shape of the molded product 100 will be described. Figure 12 with the first embodiment Figure 9 Similarly, in the molded article 100 of the present embodiment, an enlarged view of a region AR near the cross section of the second cutting portion 103 is shown.

[0173] Such as Figure 12 As shown, the molded product 100 in this embodiment has a concave guide portion 112 a corresponding to the second cutting position 112 and a concave guide portion 113 a corresponding to the third cutting position 113 . In addition, in Figure 12 In the example shown, there are guide parts 112a and 113a, but the molded product 100 has...

Abstract

The present invention provides a manufacturing method of a cover, a molded article, and a mold for molding which are capable of suppressing an increase in manufacturing cost in the production of a cover using blow molding. The manufacturing method of the cover includes a molding step of molding the molded article (100) by blow molding and a separation step, wherein the molded article (100) has a first cover portion (102) and a second cover portion (104) for the cover and a first cut portion (103) that is in contact with the first cover portion (102) and the second cover portion (104); and in the separating step, the molded article (100) is cut and to respectively separate the first cover portion (102), the first cut portion (103), and the second cover portion (104).

Description

technical field [0001] The present invention relates to a method for manufacturing a cover, a molded product, and a mold for molding. Background technique [0002] Some bed devices such as stretchers have a lifting function for raising and lowering the bed portion, and actuators such as hydraulic cylinders may be used as the lifting device. In addition, a structure in which a cover is provided around a hydraulic cylinder is also known as an elevating device. The cover prevents body fluids, dust, and the like from adhering to the hydraulic cylinder, and prevents the user from touching the sliding portion of the hydraulic cylinder. In addition, the hydraulic cylinder is covered with a cover, and the cover also has the effect of improving the appearance by imparting a sense of thickness, a sense of security due to the size, and the like. As one of such covers, there is known a telescoping cover that expands and contracts in accordance with expansion and contraction of hydraul...
