Abstract
The utility model discloses a quick de-molding device for furan resin sand molding. The quick de-molding device consists of a rectangular worktable, a heating device and a temperature control device, wherein the heating device is an electric heating pipe; the temperature control device comprises a temperature measurement thermocouple and a temperature controller; the temperature controller is connected with the electric heating pipe and the temperature measurement thermocouple respectively and is connected with a power supply. According to the characteristics of molds and resin sand products, different heating processes can be set, the ambient temperature for curing resin sand can be determined, the hardening can be accelerated, the production efficiency can be improved effectively, and the potential quality hazards of products can be avoided.
Description
Technical field
The utility model relates to a kind of phenolic sand molding coremaking equipment, especially a kind of furane resins sand molding fast demolding device.
Background technology
Furan resin self curing sand is one of casting technique with fastest developing speed over nearly more than 20 years, foundry goods by Furan Resin-Bonded Sand, size is accurately, any surface finish, corner angle are clear, percent defective is low, and can save moulder time, enhance productivity, improve working conditions and production environment; Resin sand sclerous reaction needs the regular hour, after molding and core making, must wait molding sand sclerosis to set up after some strength just can molding, but molding too early is easily out of shape, too late molding is difficulty just, common can stripping time after moulding 20 minutes to 40 minutes, this has just had a strong impact on turnover rate and the production efficiency of mould; Under the definite condition of the additional proportion of resin and curing agent, the speed of resin sand sclerous reaction and time are subject to the ambient temperature effect of production scene very large: environment temperature is low, sclerous reaction speed is just slow, time is just long, production efficiency is just low, otherwise sclerous reaction speed is just fast, time is short, and production efficiency improves; In actual production, the additional proportion of resin and curing agent is determined, if direct labor wants to enhance productivity, the normal way that adopts flame heating mould or resin sand surface, impels resin sand to add rapid hardening at present, do like this quality that can affect resin bonded sand mould and loam core, and flame heating mould is a kind of local heat, easily make mould local deformation, finally affect the quality of foundry goods, this is also to violate operating procedure simultaneously, is that factory firmly forbids.
Summary of the invention
Low in order to overcome existing phenolic sand molding coremaking production efficiency, or illegal operation raising efficiency, reduce the deficiency of resin sand product quality, the utility model provides a kind of furane resins sand molding fast demolding device, can effectively enhance productivity, avoid raising the efficiency merely reduction resin sand product quality hidden danger.
The utility model solves the technical scheme that its technical problem adopts: a kind of furane resins sand molding fast demolding device, and it has a rectangular table, it is characterized in that: it also contains heater and temperature control equipment; Described heater is electric heating tube, is close to the reverse side of rectangular table one side platform; Described temperature control equipment comprises temperature thermocouple and temperature controller, and described temperature thermocouple is close to the reverse side thermal treatment zone of rectangular table one side platform, and described temperature controller is connected with temperature thermocouple with electric heating tube respectively, and is connected with power supply.
Accompanying drawing explanation
Fig. 1 is a kind of furane resins sand molding of the utility model fast demolding device structural representation.
In Fig. 1,1, workbench, 2, temperature thermocouple, 3, electric heating tube, 4, temperature controller.
The specific embodiment
Below in conjunction with 1 pair of a kind of furane resins sand molding of the utility model fast demolding device of accompanying drawing, be described further.
A kind of furane resins sand molding fast demolding device shown in Fig. 1, by a rectangular table 1, two electric heating tubes 3, two temperature thermocouples 2 and two temperature controllers 4 form, two electric heating tubes 3, between two temperature thermocouples 2 and two temperature controllers 4, it is coordination, two electric heating tubes 3 adopt W type electric heating tube, be close to respectively the reverse side of rectangular table both sides platform, two temperature thermocouples 2 are close to respectively the reverse side thermal treatment zone of rectangular table both sides platform, two temperature controllers 4 are connected with temperature thermocouple 2 with the electric heating tube 3 of the left and right sides respectively, and be connected with power supply.
Said electric heating tube 3 can adopt U-shaped electric heating tube, or adopts many linear pattern electric heating tubes, or adopts the electric heating tube of other shapes.
Operation principle: before molding and core making according on mould size and number of molds design temperature controller 4 specified, lower limit temperature, switch on power, to one-sided electric heating tube 3 energisings, or simultaneously to 3 energisings of both sides electric heating tube, workbench 1 thermal treatment zone starts to heat up, on workbench 1 thermal treatment zone, must deposit some waste molding sands, to reduce the heat radiation of workbench 1, and the conduction of the heat between safeguard work platform 1 and mould is smooth and easy, the operating temperature of two temperature thermocouple 2 difference 1 two thermals treatment zone of surveying work platform, when reaching the specified ceiling temperature of temperature controller 4 settings, corresponding electric heating tube 3 power-off, during specified lower limit temperature that the temperature of measuring when temperature thermocouple 2 is set lower than temperature controller 4, corresponding electric heating tube 3 energisings, so, the temperature of controlling workbench 1 thermal treatment zone is specified upper, between lower limit temperature, then, direct labor carries out molding and core making on the non-thermal treatment zone of workbench 1, mould after molding and core making is moved and is put into workbench 1 thermal treatment zone, after 2 minutes to 6 minutes, molding sand just can reach molding hardness, direct labor just can form removal carry out next molding and core making.
A kind of furane resins sand molding of the utility model fast demolding device has been controlled the efficiency of the resin sand demoulding completely, because resin sand curing reaction rapidly and uniformly under the environment temperature of setting, can set different heating processes according to the feature of mould and resin sand product, determine the environment temperature that resin sand is curing, this temperature can be fixing by locking, not controlled by operator, thereby the production efficiency of effectively raising has guaranteed product quality.
It needs to be noted, the mode of above-described embodiment only limits to describe the present embodiment, but the utility model is confined to aforesaid way incessantly, therefore and those skilled in the art can modify easily accordingly within not departing from scope of the present utility model, scope of the present utility model should comprise principle that the utility model discloses and the maximum magnitude of new feature.
