Abstract
The invention discloses a door closure of a washing machine and a manufacturing method thereof. A door frame of the door closure of the washing machine has an integral structure by injection molding. A mold is needed only, and the door closure of the washing machine is subjected to injection molding by using a glass insert. Thus, the using amount of raw materials is saved, assembly is not needed, and manufacturing cost is reduced; and moreover, a product has a compact structure, and the airtightness of the product is higher than that of an assembled product.
Description
Technical field
The present invention relates to a kind of washing machine, especially a kind of door for washing machine and preparation method thereof.
Background technology
Washing machine is under the effect of washings and washing agent, by processes such as washing, cleaning, dehydration, oven dry, isolates the device of dirt and clean clothing from clothing.In washing machine, behind input washing agent and washings and the clothing, cylinder is rotated by the driving force of motor, and in the process that falls after being lifted clothing is washed in the cylinder that level is installed.Above-mentioned washing machine can also reduce the use amount of washings simultaneously to almost not damage and can prevent that clothing is intertwined mutually of clothing, and has and beat the clean result of washing by rubbing with the hands.The door closure of above-mentioned washing machine comprises the door glass that can observe the washing machine drum inner case, and the front and back doorframe of being made by the injection moulding of synthetic resin material that surrounds a glass.Because doorframe adds the assembling mode of glass before and after having adopted, need two molds, exploitation and manufacturing cost height, product thickness is thicker.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of as long as a mold adopts the door for washing machine and the manufacture method thereof of glass mold insert single injection-molded.
Door for washing machine of the present invention comprises a glass and the door frame that surrounds described door glass, it is characterized in that described door frame is the integral structure that adopts injection mo(u)lding.
Further, described door closure one side is connected with the front surface hinge of washer cabinet, opposite side handlebar hand hole, and having in the grip hole can be with the hook assembly of door closure and casing surface lock.
A kind of production method that is used for described door for washing machine may further comprise the steps:
(1) the door glass to bending carries out the edging cleaning-drying;
(2) the door glass of the bending that will handle well is positioned in the mould;
(3) temperature of heating mould is to the 15-100 degree;
(4) plastic pellet is heated to the 180-280 degree, injects mould, carry out mold-closing injection;
(5) cooling 15-60 takes out finished product after second.
Further, before to plastic pellet heating injection moulding plastic pellet is carried out drying, be 2-4 hour drying time, and baking temperature is the 75-90 degree.
The invention has the beneficial effects as follows: only need a mold, adopt the injection mo(u)lding of glass mold insert, like this, the conservation consumption need not assemble, and reduces manufacturing cost, and, product with compact structure, good airproof performance is in assembled product.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
