Abstract
The utility model relates to a hot core box lengthening fire mouth, which consists of a fire mouth and a connecting pipe, the fire mouth is connected with the connecting pipe through screw threads, the other end of the connecting pipe is connected with a heating plate through external screw threads, the length and the quantity of the connecting pipe are set according to the requirement of the cavity depth. The lengthening fire mouth has the advantages that the lengthening fire mouth has simple structure , is convenient and practical, can cause every part of the hot core box die cavity to be evenly heated, can cause the sand core sintering layer not to be easy to crack, is in particular suitable for heating the core box that the difference of the cavity depth is bigger, can not only increase the quality of the sand core, but also can effectively increase the productivity effect of the sand core as the heating time of the cavity is greatly shortened.
Description
(1) technical field
The utility model relates to the hot box heater, particularly a kind of hot box lengthening nozzles.
(2) background technology
Existing casting industry generally adopts hot box process to make core.Nozzles are critical components in the hot box process, and the employed nozzles of present most producers are unified size.For the essentially identical core box mould of depth of cavity, the efficiency of heating surface is relatively good; If but core box mold cavity depth disparity is bigger, then heating the time that needs can be longer, particularly can cause being heated of core each several part inhomogeneous, causes the sinter layer thickness difference of core, is easy to generate the cracking of core.
(3) utility model content
The purpose of this utility model is the problem that exists in the above-mentioned production, provide a kind of simple in structure, convenient and practical, make that the die cavity each several part is heated evenly, the core sinter layer is not easy to crack, shorten heat time heating time and can improve the hot box lengthening nozzles of core production efficiency.
The technical solution of the utility model:
A kind of hot box lengthening nozzles is characterized in that: by nozzles with take over and forms, for being threaded, the other end of adapter is connected with heating plate by external screw thread between nozzles and the adapter, and the length of adapter and quantity are set according to the needs of depth of cavity.
A kind of above-mentioned hot box lengthening nozzles, it is characterized in that: adapter is one group, is provided with by the length multiple.
A kind of above-mentioned hot box lengthening nozzles, it is characterized in that: it is 20mm that length increases radix.
The utility model has the advantages that: this lengthening fire nozzle structure is simple, convenient and practical, can make that hot box mold cavity each several part is heated evenly, the core sinter layer is not easy to crack, be particularly suitable for the bigger core box of depth of cavity difference is heated, can not only improve the quality of core, and owing to shortened the heat time heating time of die cavity greatly, so can effectively improve the production efficiency of core.
(4) description of drawings
Hot box lengthening fire nozzle structure schematic diagram.
Among the figure: 1. nozzles 2. are taken over 3. heating plates
(5) specific embodiment
Embodiment: see accompanying drawing
A kind of hot box lengthening nozzles, by nozzles 1 with take over 2 and forms, for being threaded, the other end of adapter is connected with heating plate 3 by external screw thread between nozzles 1 and the adapter 2, and the length of adapter 2 is set at 80mm according to the needs of depth of cavity.After using the lengthening nozzles, sintering time has saved 50%; And because core each several part sinter layer is even, does not have the phenomenon of rupture that causes because of the sinter layer uneven distribution and take place, result of use is good.
Claims (3)
1. hot box lengthening nozzles is characterized in that: by nozzles with take over and forms, for being threaded, the other end of adapter is connected with heating plate by external screw thread between nozzles and the adapter, and the length of adapter and quantity are set according to the needs of depth of cavity.
2. hot box lengthening nozzles according to claim 1, it is characterized in that: adapter is one group, is provided with by the length multiple.
3. hot box lengthening nozzles according to claim 2, it is characterized in that: it is 20mm that length increases radix.
