Abstract
A gas heater for metal mold type gravity casting dies comprises a group of horizontal hollow steel tubes (1), a group of longitudinal hollow steel tubes (2), a branched tube (3) and a group of flame nozzles (4). The gas heater has the advantages that the invested fabrication cost is low, and only the seamless steel tubes and the flame nozzles need to be put into use; moreover, the gas heater can be designed and arranged according to the requirements of a die structure and temperature, the gas heater can be mounted on any part of a die, such as an upper die, a lower die or a core-pulling part, and not only is cost reduced, but also benefit is increased.
Description
Technical field
The present invention is specifically related to metal mold gravity casting field, is specifically related to a kind of gas-operated thermal bath facility for metal gravity casting die.
Background technology
At present, the many employing electrical heating at present of the mode of heating of metal gravity casting die or firelocks heating.By process numerous bottoming hole on mould, and put 1 to 2.5kw electric heating tube at hole lining, the mould upper and lower mould of general one meter long heats nearly 10 hours, mold temperature just can reach more than 380, and some position of mould has mould ejection bar can not process bottoming hole, and the efficiency of heating surface of mould is affected to some extent.Another conventional firelock heating, need to put four above firelock heating for large mold, easily makes mold heated inhomogeneous, and has the risk of heating mould distortion.
Utility model content
The purpose of this utility model is exactly for above-mentioned deficiency, and a kind of gas-operated thermal bath facility for metal gravity casting die is provided.
The utility model is made up of one group of horizontal hollow steel pipe, one group of longitudinal hollow steel pipe, breeches pipe and one group of bocca, one group of horizontal hollow steel pipe and one group of longitudinal hollow steel pipe weld together respectively, and be network structure, every horizontal hollow steel pipe and one group of longitudinal hollow steel pipe communicate, on one group of horizontal hollow steel pipe and one group of longitudinal hollow steel pipe, have one group of venthole, one group of bocca is arranged on respectively on one group of venthole, and breeches pipe one end and horizontal hollow steel pipe wherein and wherein a longitudinal hollow steel pipe communicate.
One group of horizontal hollow steel pipe and one group of longitudinal hollow steel pipe are one.
One group of horizontal hollow steel pipe and one group of longitudinal hollow steel pipe are respectively seamless steel pipe.
The utility model advantage is: input cost of manufacture is low, only needs to drop into seamless steel pipe and bocca; And can and arrange heater according to the demanding party design of mould structure and temperature, this heater can be installed in any position can to realize upper mould, counterdie, loose core etc., has reduced cost and has improved again benefit.
accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is venthole and bocca structural representation.
Fig. 3 is the utility model mounting structure schematic diagram.
The specific embodiment
As Fig. 1, 2, shown in 3, the utility model is by one group of horizontal hollow steel pipe 1, one group of longitudinal hollow steel pipe 2, breeches pipe 3 and one group of bocca 4 form, one group of horizontal hollow steel pipe 1 and one group of longitudinal hollow steel pipe 2 weld together respectively, and be network structure, every horizontal hollow steel pipe 1 and one group of longitudinal hollow steel pipe 2 communicate, on one group of horizontal hollow steel pipe 1 and one group of longitudinal hollow steel pipe 2, have one group of venthole 5, one group of bocca 4 is arranged on respectively on one group of venthole 5, breeches pipe 3 one end and horizontal hollow steel pipe 1 wherein and wherein a longitudinal hollow steel pipe 2 communicate.
One group of horizontal hollow steel pipe 1 and one group of longitudinal hollow steel pipe 2 are one.
One group of horizontal hollow steel pipe 1 and one group of longitudinal hollow steel pipe 2 are respectively seamless steel pipe.
Occupation mode: when use, first this device is arranged on metal gravity casting die, on breeches pipe 3, connect respectively gas valve and air valve, then by breeches pipe 3 to passing into combustion gas and air respectively in one group of horizontal hollow steel pipe 1 and one group of longitudinal hollow steel pipe 2, finally igniting can heat mould.
Claims (3)
