Problems solved by technology
Existing bathtub molds are all single, that is, one bathtub corresponds to one mold. If the length or style of the bathtub is changed, the mold must be remade. This is very consumable, time-consuming, and the production cycle is relatively long. Mass production is difficult.

Embodiment 1
[0024] Such as figure 2 As shown, the segmented mold of the bathtub includes a front end section 11, a rear end section 12, and three 1m middle sections 13. The front section 11 and one middle section 13 are bolted through the bolt holes on the flange 2 of the two. Connect the other two middle sections 13 with bolts through the bolt holes on the flange sides 2. Finally, the middle section 13 and the rear section 12 that are not connected at one end of the flange side 2 are bolted through the two sections. The bolt holes on the flange 2 are connected to form a connected overall mold; a polyester layer with a thickness of 3mm is evenly laid on the connected overall mold and placed for 25 minutes to form a bathtub mold; a 3mm thick acrylic plate After heating, it is placed on the mold, and the acrylic bathtub shell is vacuum formed by a vacuum forming machine; a glass fiber board with a thickness of 13mm is placed on the bottom of the bathtub as an additional support, and then th...

The invention relates to the technical field of sanitary appliances, in particular to an acrylic bathtub manufacturing process which includes the following steps: 1 manufacturing a mould of a bathtub; 2 molding; 3 manufacturing a reinforcing layer; 4 solidifying; 5 trimming. The mould of the bathtub is flexible and formed by connecting mould sections. People can simply increase or reduce the number of middle sections to manufacture bathtubs of different lengths without changing the front section and the rear section. Further, the front section and the rear section can be used repeatedly. The people can change the style of the front section and the rear section to manufacture bathtubs of different styles. Therefore, the manufacturing process saves raw materials, reduces manufacture period, and provides guarantee for batch production. The acrylic bathtub manufactured in the process is light in weight, smooth ins surface, not prone to deformation, not prone to color fading, good in heat insulation performance, warm in touch, capable of keeping water temperature for long time and easy to wipe clean.
Description
Technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a manufacturing process of an acrylic bathtub. Background technique [0002] The bathtub can be a component of the sanitary room or used alone. It is generally a rectangular bathtub, and there are also polygonal, oval and other bathtubs, which are made according to different mold shapes. The bathtub can be laid by hand or sprayed. Surface mats and chopped mats are now used, and strive to decorate gorgeously, beautifully and practically. Whether hand lay-up or spray-molded bathtub, mold is the key. At present, most of the bathtubs are made of acrylic material. The advantages of acrylic bathtub are: it will not rust, will not be corroded and it is very light, smooth surface, diverse styles, not easy to deform, not easy to fade, good insulation performance, warm touch, can keep the water temperature for a long time, and easy to wipe clean. High-quality acrylic cylinders can mai...
