Description
Technical field
The utility model relates to the hot box technical field of mold, specifically is meant a kind of casting chaplet box mould.
Background technology
Hot box process is the method that a kind of machine is made core in the Foundry Production.The sand material that foundry sand, thermosetting resin and catalyst mix become is injected in the core box with heater; Be heated to 250～320 degrees centigrade, make the sand material on core box surface to be heated, under temperature action; Its binding agent gets final product polycondensation and hardens in very short time; Form core, must not advance the baker oven dry again, have advantages such as the production cycle of shortening.And; As long as having millimeter to form duricrust, the top layer of core can take out from core box; The core of core utilizes waste heat and sclerous reaction liberated heat to harden voluntarily; (the core thickest is generally 50～75mm) a kind of very effective method is provided, and is specially adapted to the castings production of automobile, tractor or similar industry for the high middle or small core of quick production dimensional accuracy for it.Foundry sand is generally through penetrating in the die cavity that Sha Zui injects the hot box mould, and shown in casting chaplet box mould of the prior art such as the accompanying drawing 1, it comprises penetrates sand mouth 103, goes up core box body 102 and following core box body 101; Be provided with die cavity 105 between last core box body 102 and the following core box body 101, last core box body 102 is provided with the tamper of penetrating that communicates with die cavity 105 and overlaps 104, and penetrating tamper cover 104 mainly is in the Guide casting sand directive die cavity; In use penetrate sand mouth 103 directly with last core box body 102 on the tamper cover 104 of penetrating join; Be not inserted in the core box body 102, after coremaking is accomplished, penetrate above the last core box body 102 and can leave one section sand rod that links to each other with core body in the tamper cover 104 like this; In conjunction with accompanying drawing 2; Coremaking accomplish the back product can on leave sand rod 201, this section sand rod 201 is because the sands of penetrating in the tamper cover 104 do not have cooling processing, very rapid hardening of meeting after penetrating sand mouth 103 and breaking away from; Can not accomplish the back at system sand and handle at once, need process once more the sand rod is cut away and polishes sand rod and core body gap bright and clean.In sum, the sand mouth 103 of penetrating of the prior art has the sand rod to produce in penetrating the sand process, has caused the waste of sand, has brought the molding difficulty to coremaking simultaneously, has increased core finishing polishing operation.
Summary of the invention
