Background technology

Sand grain surface promptly is covered with the molding sand or the core sand of one deck hard resin film before moulding, together roasting casing tech is arranged in precoated sand rough-cast technology, and existing roasting shell machine is very original, and mainly contain following worn-out end: 1, heat insulation effect is very poor, the serious waste energy; What 2, use is common molybdenum nickel electric furnace heating wire, disconnected easily, very big to the ordinary production influence; 3, founding by hand, the thickness of the shell of making is irregular, gives birth to ripe differing, and shell is mashed easily, the product quality that influence casts out; 4, non-uniform temperature in the stove, the shell of making is given birth to ripe differing, and therefore mashed easily shell is badly in need of wanting the roasting shell machine of a kind of novel precoated sand, to improve the quality of production, energy savings.

The utility model content

The primary and foremost purpose of the utility model is to provide that a kind of mechanization production degree is high, good product quality the roasting shell machine of precoated sand, the concrete scheme of the utility model is following:

A kind of precoated sand is baked the shell machine, but comprise baking box translation and upset die frame, sandbox, carry the sand machine; But the die frame of said translation and upset is positioned at the opening part of said baking box; But said sandbox is positioned at the below of the die frame of said translation and upset; The said input of carrying the sand machine is positioned at said sandbox, but the said output of carrying the sand machine is positioned at the top of the die frame of said translation and upset.

Preferably, the roasting shell machine of precoated sand also comprises first cylinder, but the output of said first cylinder is connected in the below of the die frame of said translation and upset.

Preferably, the roasting shell machine of precoated sand also comprises second cylinder, but the output of said second cylinder is connected with the edge of the die frame of said translation and upset.

Preferably, but between the die frame of said translation and upset and said sandbox, be provided with the sand plate.

Preferably, but between the die frame of said translation and upset and said sandbox, be provided with screen cloth.

Preferably, but be provided with sand hopper between the die frame of the said output of carrying the sand machine and said translation and upset.

Preferably, be spaced apart 3 thermals treatment zone in the said baking box, be provided with the high-temperature electric resistance furnace silk in the said thermal treatment zone.

Preferably, said interior oven walls is provided with the high-temperature-resistant thermal-insulation plate.

The precoated sand that the utility model provides is baked the shell machine, and using electricity wisely 2/3rds has reduced cost and labour intensity, and energy-saving and emission-reduction; Operate steadily, the baking box high insulating effect is used electrical heating, and efficient is high; External form is simple and direct, and the control space is big, is convenient to tissue and produces in enormous quantities.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

Fig. 1 is the utility model example structure sketch map.

The specific embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Embodiment

As shown in Figure 1; The roasting shell machine of precoated sand comprises baking box 1, and for making baking box 1 interior each regional temperature always, the baking box 1 in the present embodiment is spaced apart 3 thermals treatment zone; Be respectively arranged with the heat silk in each thermal treatment zone; Control the temperature difference between each heater strip in 5 ℃ of scopes, consistent to guarantee the roasting shell cooking level of precoated sand in baking box 1 each zone, be difficult for mashed shell; The inwall of baking box 1 also is provided with the high-temperature-resistant thermal-insulation plate, and what present embodiment adopted is heat-preservation cotton, has substituted refractory brick commonly used, has improved heat insulation effect; Baking box 1 also is provided with the opening that is used to pass in and out material; Baking box 1 is through the unlatching of the pulley 3 control oven door 2 of top; Opening part at baking box 1 is provided with a die frame 6; But this die frame 6 is located at baking box 1 opening part for translation, turnover form, for realizing translation, the turn over function of die frame 6, adopts following scheme in the present embodiment: below die frame 6, be provided with first cylinder 8; The output of first cylinder 8 is connected with the contact of die frame 6 bottom surfaces, realizes the upset of die frame 6 through controlling first cylinder 8; Die frame 6 sides be provided with second cylinder, 10, the second cylinders 10 fixing with a column 15 on, be hinged with a rocking arm 9 on the column 15; rocking arm 9 is connected through hook 14 with the edge of die frame 6; output of second cylinder 10 is connected in hook 14 places, make the edge of output and die frame 6 of second cylinder 10 be and be in transmission connection, through the translation of second cylinder, 10 realization die frames 6; and with second cylinder 10 be fixed in column 15 be for the operation that makes second cylinder 10 more steady; the output of second cylinder 10 and die frame 6 pass through to link up with 14 transmissions, make second cylinder 10 more simple with being connected of die frame 6, are convenient to installation.
