Detailed Description

The present invention provides a bathtub mold, and in order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Here, the opening direction of the molding cavity 21 of the fixed mold 2 is set to be upward (or top), and the installation direction of the movable mold 3 with respect to the molding cavity 21 is set to be forward.

Referring to fig. 1, the present invention provides a bathtub mold for manufacturing a sector-shaped bathtub 1 made of an acrylic plate having a convex portion 11 on the front side as shown in fig. 2. The bathtub mold includes a movable mold 3 made of an aluminum alloy, and a fixed mold 2 made of a resin such as an epoxy resin.

As shown in fig. 1 and 3, the fixed mold 2 is provided with a molding cavity 21 for bathtub plastic molding; the movable mould 3 is attached to the fixed mould 2 and positioned at the front side of the fixed mould 2, the movable mould 3 can be directly placed on the fixed mould 2 and attached to the fixed mould, and the stable state can be kept so as to facilitate the plastic suction molding process of the bathtub. The movable mold 3 and the fixed mold 2 together form a convex cavity 22 which is located at the front side of the molding cavity 21 and is communicated with the molding cavity 21.
