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

[0040] Such as Figure 1-4 As shown, an automatic molding and casting device for home appliance base products includes a base, a vacuum molding table panel 3 and a sand box. The base is set on the vacuum molding table panel 3. The mold model 2 and the lower mold model 1, the upper mold model 2 is set in the lower mold model 1, the upper mold model 2 and the lower mold model 1 are obtained by parting the base, and the parting surface is selected as the bottom surface of the base, in order to facilitate the modeling Operation, the upper die model 2 is made into a convex shape with the parting surface as the zero point, so that the upper die model 2 and the lower die model 1 are both convex. Both sides of bottom edge of lower mold model 1 are outwardly provided with projections 101, which are convenient to take the model after the molding. The middle of the upper mold model 2 is provided with a hole for connecting the wooden rod of the casting system, and the lower mold model 1 ...

Embodiment 2

[0049] 1. Make the base three-dimensional ( figure 1 As shown) use 3D software to carry out the mold splitting operation, choose the mold parting surface as the bottom surface, and the separated models are the lower mold model 1 and the upper mold model 2, and the upper mold model 2 is the inner shape, but for the convenience of modeling Operation, therefore, the upper die model 2 should be made into a convex shape with the parting surface as the zero point, so that the lower die model 1 and upper die model 2 models are both convex.

[0050] 2. Send the output of the lower mold model 1 and the upper mold model 2 to the model processing workshop for processing, and the obtained casting model is to be cast;

[0051] The materials used in the above-mentioned casting models (lower mold model 1 and upper mold model 2) are made of the following components in parts by weight: 100 parts of ABS, 8 parts of plastic plasticizers, 5 parts of straw powder, monocyclic carboxylic acid 1.5 p...

Abstract

An automatic molding and casting device for home appliance base products is characterized by comprising a base, a vacuum molding countertop and a sand box; the base is arranged on the vacuum molding countertop and sleeved with the sand box; the base is divided into an upper molding model and a lower molding model; and the upper molding model is arranged in the lower molding model. After the V method models are optimized in design, the models can be rapidly replaced easily and fast machining forming of the models can be achieved easily, and the device is suitable for a small-batch multi-variety production mode.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to an automatic molding casting device for home appliance base products, which is especially suitable for V-method casting of aluminum alloy home appliance moulds. 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 cov...
