Problems solved by technology

In this way, not only the operating efficiency is low, but the labor intensity of the workers is high, and the quality of the castings is difficult to guarantee.
After adopting the v-method process for production, the operation efficiency has been greatly improved and the product quality has been improved. However, the shape and structure of the aluminum alloy mold castings in the household appliance industry are complicated. According to the normal V-method model and casting process, the model cannot be coated or removed after molding. model and other issues

Embodiment 1

[0061] 1) Use the three-dimensional software to perform parting operation on the upper box, select the parting surface as the bottom surface, and the separated models are the rib model of foam material, the upper box upper mold model 62 adapted to the chamber, and the convex The upper box lower mold model 61 adapted from 5, wherein the upper box upper mold model 62 is an inner shape, in order to facilitate operation in the modeling, so the upper box upper mold model 62 and the upper box body should be taken as the zero point of the parting surface Make a convex shape, so that the above models are all convex;

[0062] 2) Send the output of the upper box body lower mold model 61, the upper box body upper mold model 62 and the rib model to the model processing workshop for processing, and the obtained casting model is to be cast;

[0063] 3) Place the upper mold model 62 of the upper box on the vacuum molding table panel 63 of the upper box, and control the negative pressure at 0...

Embodiment 2

[0069] 1) Use the three-dimensional software to carry out the parting operation of the lower box, select the parting surface as the bottom surface, and the separated models are the lower box lower mold model 81 and the lower box upper mold model 82, wherein the lower box upper mold The model 82 is an inner shape. In order to facilitate operation in the molding, the upper mold model 82 of the lower box body is made into a convex shape with the parting surface as the zero point, so that the above-mentioned models are all convex;

[0070] 2) Send the output of the lower box lower mold model 81 and the lower box upper mold model 82 to the model processing workshop for processing, and the obtained casting model is to be cast;

[0071] 3) Place the lower box lower mold model 81 on the lower box vacuum molding table panel 83, and control the negative pressure at 0.05Mpa. After baking and covering, put the No. 1 sandbox 84 of the lower box on the lower box On the lower mold model 81, ...

Embodiment 3

[0077] The V method casting coating includes the following components by weight: 100kg of composite refractory powder, 4kg of organic binder, 4kg of suspending agent, 1kg of auxiliary agent, and 40kg of solvent, wherein the particle size of the composite refractory powder is 5um. Prepared in the following steps:

[0078] S1. Prepare composite refractory powder, put zircon powder, graphite, bauxite, and iron red into a ball mill for ball milling, make it evenly mixed, and obtain a particle size of 3-7um;

[0079] S2. Mix the prepared refractory powder with other remaining ingredients, put them into a high-speed mixer, stir and disperse at a speed of 16000 rpm for 3 hours to obtain a mixture;

[0080] S3, put the mixed material into a ball mill for ball milling, so that the particle size of the obtained slurry is below 15 μm, and adjust the viscosity as required, to obtain final product;

Abstract

The invention relates to the technical field of casting, and particularly relates to a home appliance door type plate and a preparation process thereof. The home appliance door type plate comprises anupper case and a lower case matched with the upper case, wherein the upper case and the lower case have the same structures; the upper case comprises a cavity in a rectangular groove shape as a whole; an inner cavity enclosed by the cavity is divided into a plurality of chambers for placing parts through clapboards; arc-shaped openings for wiring are respectively formed in two ends of the cavity;rectangular notches matched with installation pieces are formed in a side wall of the cavity; a bulge is also arranged on one end face, far away from the clapboards, on the cavity; a plurality of clamping slots for fixing are also formed in a circumferential surface of the outer side of the bulge. Therefore, through the preparation process provided by the invention, home appliance industry aluminum alloy mold castings with complicated structures and shapes can be manufactured, a lost foam process is used in a traditional V-method casting process, and a mold taking process is avoided, so thatthe yield of the castings is improved, and the problem that the mold cannot be taken after modelling is solved.

Description

Technical field: [0001] The invention relates to the field of casting technology, in particular to a hair type plate for a household appliance door and a preparation process thereof. Background technique: [0002] V-method vacuum molding is the third-generation molding method after mechanical molding and chemical molding. The specific process is to prepare a mold with a pumping chamber. There are vent holes on the mold that can be directly connected to the vacuum tube of the pumping chamber. The EVA film is placed under the film dryer and heated to a softened state. Through the air holes on the mold, the vacuum is applied to the softened plastic film to make it closely adhere to the mold. The negative pressure sand box is placed on the mold, and the sand box is covered. The dry sand is filled, and the dry sand obtains the maximum density through the vibrating equipment. The top of the sand mold is covered with a layer of sealing film, and the sand box is evacuated to cause a...
