AI Technical Summary

Technical Problem

Existing bathtub molds are difficult to meet the needs of complex shapes. Acrylic bathtub molds require air holes and air channels to provide thermal stability and resistance to the impact of temperature changes, while artificial stone bathtub molds are difficult to demold and are prone to damaging the product.

Method used

CNC milling of wooden molds replaces traditional plaster molds, and complex bathtub molds are prepared through machining. Clamping devices are used to fix the wooden boards to prevent displacement, and they are reinforced with water wax, unsaturated resin and fiberglass. Finally, air holes are opened on the surface of the mold.

Benefits of technology

It enables precise and efficient fabrication of complex bathtub molds, avoiding mold misalignment and damage, and improving the mold's heat resistance and ease of demolding.

Abstract

The present application relates to a kind of preparation methods of bath production mould based on CNC, comprising the following steps: S1, several wood boards are stacked to be placed on tray and are positioned, and the fixing is carried out between every two adjacent wood boards;S2, then the stacked wood board is processed;S3, after processing, the R corner of wood mould and the joint of wood board are polished, and the pit on wood mould is filled;S4, water wax is applied on the surface of wood mould, then unsaturated resin and glass fiber reinforced plastic are applied;S5, after unsaturated resin is completely cured and dry, PVC plastic tube is placed at waterproof edge, corner and drain, and PVC plastic tube is fixed;S6, opening is made on PVC plastic tube, stainless steel pipe joint is placed, and glass fiber reinforced plastic and unsaturated resin are laid on interface;S7, when unsaturated resin is completely cured and does not stick to hand, demoulding work is carried out.The present application can more accurately and efficiently prepare the bath mould with complex and special shape.
