Abstract
Disclosed is a heating device for automatic drawing blocks of a hot-core box. The heating device comprises a static die and a moving die, more than one drawing block is mounted in a groove of the static die, and the static die, the moving die and the drawing blocks are mutually and correspondingly buckled together to form an integral core box; a cylinder is mounted to the bottom or side face of the core box, and a piston rod of the cylinder and the drawing blocks are fixed into a whole; a plurality of blind holes are evenly distributed in the outer side of each drawing block, an electric heating tube is mounted in each hole, the electric heating tubes are connected in parallel, and the electric heating tubes and electric heating tubes of a core box body perform heating at the same time. By virtue of mounting the electric heating tubes on the drawing blocks, the automatic drawing blocks are heated continuously and evenly, heating temperature of the core box drawing blocks is increased highly, curing degree of sand cores made with the hot-core box is guaranteed effectively, gas generating amount of the sand cores is lowered greatly, quality of the sand cores is ensured, and production efficiency is improved.
Description
Technical field
The present invention relates to the mould of sand cores of castings, paint relates to the heater that block taken out automatically by a kind of hot box.
Background technology
Along with the fast development of automobile industry, the quality requirement of auto parts and components is also more and more stricter, there is pore greatly can reduce the performance of foundry goods in foundry goods, the ripe degree of solidification of sand cores of castings is directly connected to the gas forming amount of core, if core takes out block, site curing degree is poor, more containing greensand, the gas produced during casting is just more, gas invades in foundry goods, form pore, therefore in order to ensure the ripe degree of the solidification of core, must ensure that core box is taken out block and met the requirements of heating-up temperature, it is generally that the direct baking that manually applies a torch takes out block position that existing core box takes out the mode of heating that block adopts automatically, every mould or toast a period of time every a few mould, not only take out deblocking temperature to be difficult to ensure, and time-consumingly to take a lot of work, make core solidification uneven, difficult quality guarantee, and production efficiency is low.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcome the above-mentioned defect that prior art exists, and provide a kind of hot box automatically to take out the heater of block, by installing electrothermal tube taking out on block, to automatically taking out the heating of block continuous uniform, the heating-up temperature that core box takes out block greatly can be improved, effectively ensure that the ripe degree of solidification of core made by hot box, greatly reduce core gas forming amount, ensure that core quality, improve production efficiency.
The technical solution adopted for the present invention to solve the technical problems is:
A heater for block taken out automatically by hot box, comprising: quiet mould and dynamic model, is provided with more than onely to take out block in quiet mould groove, quiet mould and dynamic model and take out the mutual correspondence of block and be buckled together formation one one-piece core box; A cylinder is installed in bottom core box or side, the piston rod of cylinder with take out block and be fixed as one; Be uniformly distributed several blind hole in the outside of taking out block, install an electrothermal tube in each hole, electrothermal tube adopts in parallel, heats with core box body electrothermal tube simultaneously.
This cylinder is fixed as one by the quiet mould of support and hot box.
Evenly divide and taking out on block taking out the electrothermal tube that block is installed.
This automatically takes out block and cylinder piston is fixed as one.
The invention has the beneficial effects as follows, by installing electrothermal tube taking out on block, to automatically taking out the heating of block continuous uniform, greatly can improve the heating-up temperature that core box takes out block, effectively ensure that the ripe degree of solidification of core made by hot box, greatly reduce core gas forming amount, ensure that core quality, improve production efficiency.

Detailed description of the invention
Embodiment of the present invention composition graphs 1, Fig. 2 and Fig. 3 are described as follows, the present embodiment comprises: quiet mould 1 (as shown in Figure 1) and dynamic model 2 (as shown in Figure 2), be provided with in quiet mould groove and more than onely take out block 3, quiet mould and dynamic model and take out the mutual correspondence of block and be buckled together formation one one-piece core box; A cylinder 4 is installed in bottom core box or side, the piston rod of cylinder 45 with take out block 3 and be fixed as one; Be uniformly distributed several blind hole in the outside of taking out block 3, install an electrothermal tube 6 in each hole, electrothermal tube adopts in parallel, heats with core box body electrothermal tube simultaneously.
This cylinder 4 is fixed as one by the quiet mould of support and hot box.
Evenly divide at the electrothermal tube 6 taking out installation on block 3 and taking out on block 3.
This is automatically taken out block 3 and is fixed as one with cylinder piston.
Overall structure schematic diagram of the present invention, as shown in Figure 3.
The present invention, by installing electrothermal tube taking out on block, to automatically taking out the heating of block continuous uniform, can improve the heating-up temperature that core box takes out block greatly, effectively ensure that the ripe degree of solidification of core made by hot box, greatly reduce core gas forming amount, ensure that core quality, improve production efficiency.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
In sum, the present invention is in structural design, use practicality and cost benefit, meet completely needed for industry development, and the structure disclosed also is have unprecedented innovative structure, there is novelty, creativeness, practicality, meet the regulation of Invention patent requirement, therefore mention application in accordance with the law.
