Embodiment 1

[0026] like figure 1 As shown, the acrylic bathtub integrated molding device of the present invention includes a mold base 2 provided with a cavity 1, and a through hole 5 is opened at the bottom of the cavity 1, and the bottom of the through hole 5 is located at the mold base 2. The external vacuum pump is connected, and the top of the mold base 2 is connected with a cover 3 through a hinge. The lower surface of the cover 3 is equipped with a punch 4 matching the cavity 1, and the punch 4 is located directly above the cavity 1. A cavity is provided inside the punch 4, a heating tube 6 for heating the punch 4 is installed inside the cavity, and a clamping device for pressing the edge of the acrylic plate is provided on the mold base 2 and the upper cover 3. The heating tube 6 is a carbon fiber heating tube, and the outside of the heating tube 6 is covered with a heat conducting insulating layer. The maximum height of the convex mold 4 is smaller than the concave depth of the ...

Embodiment 2

[0029] Based on Embodiment 1, the clamping device includes at least two first suction cups 7 installed on the upper surface of the mold base 2, at least two second suction cups 8 installed on the lower surface of the upper cover 3, and all the first suction cups 7 Evenly distributed on the periphery of the cavity 1, all the second suction cups 8 are evenly distributed on the periphery of the punch 4. In the present invention, if the molding effect of the molded parts is not affected, the position of the processed acrylic sheet must be maintained in the blister molding and compression molding, so as to avoid the uneven thickness of the acrylic sheet during the molding process. In the process, the first suction cup will hold the acrylic sheet, and during the blistering process, the first suction cup and the second suction cup will cooperate with each other to hold the acrylic sheet together. In the present invention, the clamping device not only adopts a suction cup, but also ca...

Embodiment 3

[0031] Based on the above embodiment, a plurality of annular condensation pipes are installed inside the mold base 2 , and all the annular condensation pipes evenly surround the outer periphery of the cavity 1 . The annular condenser tube will be filled with condensed water during use, in order to quickly cool the acrylic plate after blistering and improve the efficiency of the integrated molding of the bathtub.

Abstract

The invention discloses an integrated forming device for an acrylic material bathtub and a bathtub forming method. The integrated forming device for the acrylic material bathtub comprises a mold base provided with a mold cavity; a through hole is formed in the bottom of a cavity body of the mold cavity; the position below the through hole is communicated with a vacuum pump located outside the mold base; the position above the through hole is connected with an upper cover through a hinge; a male mold matched with the mold cavity is installed on the lower surface of the upper cover and is located over the mold cavity; an empty cavity is formed in the male mold and is internally provided with a heating pipe for heating the male mold; and the mold base and the upper cover are each provided with a clamping device pressing the edge of an acrylic plate in a matched manner. The integrated forming device for the acrylic material bathtub integrates blister with mold pressing, the problem that the blister forming time is long is solved, the mold pressing plays a role of pre-forming, it can be guaranteed that the machined acrylic plate is in a state capable of being subjected to blister in the mold pressing process, and the blister forming time is shortened.

Description

technical field [0001] The invention relates to an integrated molding device, in particular to an integrated molding device for an acrylic bathtub and a molding method for the bathtub. Background technique [0002] The acrylic bathtub is a bathtub made of a PMMA plastic material. The acrylic bathtub is characterized by rich shapes, light weight, good surface finish, and low price; the heat transfer of the acrylic bathtub is very slow, so the heat preservation effect is good. Acrylic is made from deep sea A by-product extracted from petroleum, the cost of raw materials for making bathtubs is much lower than that of cast iron and steel bathtubs, and the performance is very good, so it has price advantages and stronger market competitiveness. The acrylic bathtub has a certain degree of self-healing properties, and the surface of the acrylic bathtub is smooth and white, and it is easy to clean. [0003] At present, acrylic integrated bathtubs are currently the most widely used ...
