In wax pan；The heater connecting with temperature controller is equipped in wax melting slot；The test block molding press includes impervious test mould steel drum, anti-
It seeps and is equipped with electromagnetic heating coil in die trial steel drum, the bottom of electromagnetic heating coil is connect with guide rod, the other end of guide rod and fixation
Spring connection on the rack, the guide rod that can slide up and down are arranged in linear bearing, electromagnetic heating coil and electromagnetic heating control
Device connection processed.
In the present invention, counter is equipped on rolling wax machine, counter is used to count the quantity of impervious coupon sample rotation.
Test block molding press is equipped with bracket, and impervious test mould steel drum is arranged on bracket.
Further, it is equipped with crossbeam in the other end of guide rod, the two of crossbeam are withered to be connect with spring.
The present invention controls wax melt temperature by temperature control wax pan, is allowed to not generate volatilization, and impervious coupon sample is flat by two
The idler wheel of row setting is placed in the wax liquor surface in wax pan, is rotate in same direction by two parallel axes and drives impervious coupon sample in wax liquor
Surface pivots are uniformly applied to impervious coupon sample side for drawing, and impervious coupon sample turnning circle can after passing through test of many times
It is set as fixed value.Liftable cylindrical shape non-contact electromagnetic heater is placed in punching block center, while test block carries out rolling wax
It is heated, after the completion of wax is rolled in test block, test block is placed in punching block center, test block is pressed by punching block by pressure apparatus, is completed
The sealing of test block and punching block.
Compared with prior art, the invention has the following advantages that sealing medium prepares conveniently, to volatilize after heating and melting
Pernicious gas is generated, convenient by equipment operation compared to hand-held test block rolling wax in the past, efficiency greatly improves, and rolls wax time and wax layer
Thickness is controllable.Integration operation is heated and suppressed by punching block, and homogeneous heating, heating temperature is controllable, easy to operate, heating speed
Fastly.Sealing medium is reusable, utmostly reduces pollution, demoulds after impermeability test and cleaning is convenient, overall work
Efficiency greatly improves.
