Technical Field

The invention relates to the field of bathrooms, in particular to a manufacturing method for manufacturing a submerged bent part in the production of an acrylic toilet bowl.

Background

At present, acrylic toilet bowl on the market all is by the closestool seat of honour, the closestool is sat, three major parts of sewage disposal system constitute, and acrylic toilet bowl 'S sewage disposal system, constitute by curved part of heavy water and the curved sewage pipes of S, because the ductility of acrylic material self is limited, present curved part manufacturing process of heavy water to acrylic toilet bowl all adopts the die plastic uptake segmentation shaping, then the rethread concatenation, scrape the ash, polish, the assembly completion is led to the wall to the many workmanship of spraying paint, again because the particularity of the curved shape of the curved part of heavy water of acrylic toilet bowl, even can once only whole shaping, also can't completely take out.

The technical defects are shown in the specification;

not only the process is complex and the production efficiency is low, but also the quality and the appearance of the product are seriously influenced

The invention content is as follows:

the invention aims to provide an integral forming method aiming at the technical defects of the existing manufacturing process of the sinking bent part of the acrylic toilet bowl, which does not need splicing and can be integrally formed at one time.

The technical scheme adopted by the invention is as follows:

the manufacturing method of the sinking bent part of the acrylic toilet bowl comprises the equipment facilities such as a forming machine cylinder, a clamp, a hard frame, a positive pressure, a negative pressure and a heating system and the like used in the production of the conventional acrylic products, and is characterized in that: the method adopts a special convex mould, changes the traditional concave mould segmentation plastic uptake splicing method into a one-time integral forming method.

The special convex die is characterized in that in the integral forming process of a submerged curved part, a die hook part for preventing the demoulding of a product is cut to form an independent hook die, one ends of two positioning pins are used for fixing, the other ends of the positioning pins respectively penetrate through two holes of a female die corresponding to the hook die, the positioning pins are in sliding fit with the corresponding holes, the other ends of the two positioning pins penetrate through the two holes and then are connected with an air cylinder, and when the air cylinder retracts, the hook die and the corresponding female die are combined into the special convex die.

The integral forming is that a special air cylinder for controlling the transverse movement of the U-shaped crease-resistant pressing bar is added on a clamp of a forming machine, and the traditional female die plastic suction sectional forming splicing method is changed into a one-time integral wrapping forming method of a special male die.

The invention is realized as follows:

firstly, cutting off a die hook part which hinders demoulding of a product in the integral manufacturing process of a submerged curved part to manufacture an independent hook die, fixing one ends of two positioning pins, enabling the other ends of the positioning pins to respectively penetrate through two holes of a female die corresponding to the hook die, enabling the positioning pins to be in sliding fit with the corresponding holes, connecting the other ends of the two positioning pins with a small air cylinder to form a specially-made special convex die, and adding a special air cylinder for controlling the telescopic transverse movement of a U-shaped crease-resistant pressing strip on a clamp of a forming machine.

When a submerged bending part is produced and processed, a special male die is placed on a special male die pad of a forming machine, a hard frame with proper size is selected to clamp the periphery of an acrylic plate after being heated and softened, the hard frame is fixed on a clamp driven by a cylinder of the forming machine, a small cylinder of a special male die retracts, cutting lines are superposed, the acrylic plate after being heated and softened on the hard frame is driven by the cylinder of the forming machine from top to bottom, the special male die is completely covered, a special cylinder which moves transversely retracts, a U-shaped crease-resistant batten is pressed on a bent hook of the special male die, negative pressure can be realized, the softened acrylic plate completely and tightly wraps the special male die, after a workpiece is cooled and shaped, the clamp is removed, the special cylinder extends transversely, the U-shaped crease-resistant batten is released, the cylinder of the forming machine lifts the clamp, the small cylinder of the special male die slowly extends out, the hook mold slowly rises, and meanwhile, the workpiece is ejected upwards, so that a complete sinking bent part is smoothly taken out, and one-time integral forming is realized.

The beneficial effects of the invention are shown in;

the molding method of the invention realizes one-time integral molding, which not only greatly improves the production efficiency, but also improves the product quality.
