Description

Bathtub hollow insulating layer curing mould
Technical Field
The utility model relates to a bathtub, heat preservation, mould, concretely relates to bathtub cavity heat preservation solidification mould.
Background
A bathtub is a plumbing fixture for bathing or showering, typically in a residential bathroom. Modern bathtubs are mostly made of acrylic or glass fiber, and also made of steel coated with ceramic, in recent years, wooden bathtubs are gradually prevailing in the continental china, and are mainly made of cedar wood in the sichuan region as a base material, so that the bathtub is also called a cedar barrel.
Old western style bathtubs are typically made of rust protected (galvanized) steel or iron. Since most of bathtubs have a rectangular shape, various shapes of bathtubs have been developed in recent years due to the increasing popularity of sub-force heating bathtubs. The most common color of bathtubs is white, as well as other hues such as pink. The bottom of most bathtubs is provided with a water removing level, and the upper part of the bathtubs is also provided with a water removing level for preventing full discharge. Some install the water throat on the edge of the bathtub.
The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".
The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.
The hollow forming is a processing method of fixing the tubular or sheet blank material which is made by extrusion or injection and is still in a plasticized state in a forming mould, immediately introducing compressed air to force the blank material to expand and stick to the wall surface of a mould cavity, and demoulding after cooling and shaping to obtain the required hollow product. Suitable plastics for hollow forming are high-pressure polyethylene, low-pressure polyethylene, hard polyvinyl chloride, soft polyvinyl chloride, polystyrene, polypropylene, polycarbonate and the like. Depending on the parison molding method, the hollow molding is mainly classified into two types, extrusion blow molding hollow molding and injection blow molding hollow molding. The extrusion blow molding hollow forming has the advantages that the structure of an extruder and an extrusion blow molding die is simple, and the defects that the wall thickness of a parison is not uniform, and the wall thickness of a plastic product is not uniform easily are caused. The right drawing is a schematic view of the principle of extrusion blow molding hollow molding. The injection blow molding hollow molding has the advantages that the wall thickness of the parison is uniform, no flash is generated, and the bottom of the hollow product cannot be spliced and sewed due to the bottom surface of the injection parison, so that the hollow product is attractive in appearance and high in strength. The disadvantage is that the used forming equipment and the mould are expensive, so the forming method is mostly used for the mass production of small hollow products, and the extrusion blow molding hollow forming method is not widely used.
Patent document publication No. (108995187 a) states that: bath articles such as bathtub bodies and wash basins are widely made of acrylic plates. In the prior art, at first put into the heating cabinet with inferior gram force board material and heat and soften, inferior gram force board material through the heating completion of anchor clamps centre gripping, then arrange in the accent department of the die cavity of the good mould of prefabricating, the arrangement time is longer, the process is comparatively troublesome, inferior gram force board edge part is by the outside peripheral part position of fixture centre gripping at the accent of the die cavity of mould, at this moment, the face that is close to fixture tightly is at first attached on the die cavity accent border of mould, the face of middle part large tracts of land is the deformation of extending perpendicularly to the die cavity face direction of mould naturally under the action of gravity, the die cavity and the vacuum environment intercommunication of mould simultaneously, inferior gram force board then further is close to the die cavity face deformation of mould until both attached together. In the forming process, the acrylic plate close to the clamping mechanism is firstly contacted and attached with the edge of the cavity opening of the cavity, so that the cooling is fast, the deformation of the acrylic plate at the edge part of the cavity opening of the cavity is small, the plate surface of the middle area of the acrylic plate is finally contacted with the bottom of the cavity, and in the whole forming process, the deformation of the peripheral part of the acrylic plate is small, the deformation of the middle acrylic plate is large, so that the thickness of the upper edge part of a formed product is large, the thickness of the bottom of the formed pelvic cavity is minimum, and in addition, under the condition that the cavity is deep, the bottom of the pelvic cavity is even cracked or hollowed. Thus, the yield is low, the quality is poor and the efficiency is low.
Patent document No. (201720884280.6) states that: bathtubs are the main equipment in toilets, people generally take or bathe by using the bathtubs, and the types and sizes of the bathtubs are various. When a person takes a bath, the person needs to have water to have a shoulder when taking the bath, so that the whole body can be warmed, the materials of the bathtub are various, one of the bathtub is an acrylic bathtub which is made of acrylic materials, the acrylic materials are organic plates and also are glass fiber reinforced plastic materials, and the application is very wide at present. The bright and clean acrylic material is used for producing bathtubs, containers and other similar products, and the sun-facing trend is formed in China. The existing acrylic bathtub is mainly formed by heating and softening an acrylic blank plate, then ejecting and forming the acrylic blank plate by using a mold and then demoulding, one equipment can only process one blank plate at the same time, and the blank plate needs to be cooled for a longer time during demoulding, so that the processing efficiency is lower.
The problems proposed in the above documents are mainly poor mold release effect and low yield, but the existing materials have many defects and cannot essentially solve the problems by changing the molding mode of the mold, and all the requirements are that the yield can be improved and the functions of the mold can be considered.
