Forming method for large-area soft bathtub

Abstract

The invention provides a forming method for a large-area soft bathtub. The method includes the step of injecting a high-resilience heat preservation layer between an outer mold provided with a shaping layer and an inner mold. The method is characterized in that before the high-resilience heat preservation layer is injected, a plurality of through holes are formed in the position, corresponding to the bottom of the bathtub, of the outer mold, and hooks penetrating through the through holes are used for pulling the shaping layer to the inner wall of the outer mold, so that the shaping layer is attached to the inner wall of the outer mold; and then the high-resilience heat preservation layer is injected. Compared with the prior art, the forming method for the large-area soft bathtub has the advantages that the shaping layer is prevented from falling in a mold cavity, the thickness of the high-resilience heat preservation layer is guaranteed, and it is guaranteed that the high-resilience heat preservation layer is formed in place.

Description

[0001] Technical field: [0002] The invention relates to a production method of a bathtub. [0003] Background technique: [0004] The soft bathtub is made of a shaping layer, a high-resilience insulation layer, a surface reinforcement layer, and a non-slip glossy layer. During processing, the mold is like figure 1 As shown: Including inner mold 1 and outer mold 2. During processing, the processing of the shaping layer 3 is completed first, and then the outer mold together with the shaping layer 3 is relatively separated from the inner mold, leaving a space 4 for the high-resilience insulation layer for injection The high resilience insulation layer, in actual operation, due to the large area at the bottom of the soft bathtub, the shaping layer falls in the mold cavity, and the thickness reduction and molding of the high resilience insulation layer are not in place. [0005] Invention content: [0006] The object of the present invention is to provide a method for forming a ...
