Example Embodiment

[0025] Example 1

[0026] Such as figure 1 As shown, the acrylic bathtub integrated molding device of the present invention includes a mold base 2 provided with a cavity 1. A through hole 5 is opened at the bottom of the cavity 1 and the through hole 5 is located below the mold base 2. The external vacuum pump is connected, the upper part of the mold base 2 is connected with an upper cover 3 through a hinge, and the lower surface of the upper cover 3 is equipped with a punch 4 that matches the cavity 1, and the punch 4 is located directly above the cavity 1. A cavity is opened inside the convex mold 4, and a heating tube 6 for heating the convex mold 4 is installed in the cavity. The mold base 2 and the upper cover 3 are both provided with clamping devices that cooperate and press the edge of the acrylic plate. The heating tube 6 adopts a carbon fiber heating tube, and the outside of the heating tube 6 is covered with a thermally conductive insulating layer. The maximum height ...

Example Embodiment

[0028] Example 2

[0029] Based on Example 1, the clamping device includes at least two first suction cups 7 installed on the upper surface of the mold base 2 and at least two second suction cups 8 installed on the lower surface of the upper cover 3, all of the first suction cups 7 Evenly distributed on the periphery of the cavity 1, and 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 part is not affected, the position of the acrylic plate to be processed must be maintained during blister molding and compression molding to avoid uneven thickness of the acrylic plate during the molding process. In the blister process, the first suction cup will suck the acrylic board. During the blister process, the first suction cup and the second sucker will cooperate with each other to suck the acrylic board together. The clamping device in the present invention not only uses suction cups, but a...

[0030] Example 3

[0031] Based on the above embodiment, a plurality of ring-shaped condenser tubes are installed inside the mold base 2, and all the ring-shaped condenser tubes evenly surround the outer periphery of the cavity 1. The ring-shaped condenser tube will be filled with condensed water during use, in order to quickly cool the acrylic plate after blister, and improve the efficiency of integral 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 ...
