Abstract
The utility model discloses a heater for a low-pressure casting liquefied natural gas (LNG) die for an automobile cylinder cover. The heater is characterized in that a gas supply pipe is communicated with spray nozzle gas supply pipes A on two sides; the communication parts are positioned in middles of the spray nozzle gas supply pipes A; spray nozzle gas supply pipes B are arranged between the spray nozzle gas supply pipes A on two sides; the spray nozzle gas supply pipes A are communicated with the spray nozzle gas supply pipes B; and a plurality of spray nozzles are arranged on the spray nozzle gas supply pipes A and the spray nozzle gas supply pipes B. Due to the adoption of a communication mode of adjusting pipe diameters of the gas supply pipes and supplying gas from the middle sections of the spray nozzle gas supply pipes, the gas supply amount of LNG is ensured, and heat generated by combusting the gas reaches the temperature required by die heating, so that effects of low carbon and energy conservation are achieved.
Description
Technical field
The utility model relates to mold heating device, especially a kind of automobile cylinder cap low pressure casting LNG die heater.
Background technology
Low pressure casting has pressure and adjustable-speed joint, foundry goods dense structure, clear-cut, any surface finish, and mechanical property is higher, labour intensity is low, and working condition is good, and device simple is prone to realize characteristics such as mechanization and automation, is applicable to the casting of automobile cylinder cap.In casting process, reasons such as being heated of mould is inhomogeneous, heating temperature deficiency can cause the blemish of foundry goods.
At present, general what use is LPG (liquefied petroleum gas) to the fuel of mold heated, and LPG low price, calorific value are high, but its poor stability, not environmental protection causes a hidden trouble to production environment and handling safety; LNG (liquefied natural gas) is as a kind of cleaning, efficient, convenient, the safe energy, high with its calorific value, pollute less, accumulating is convenient etc., and characteristics become one of selectable high-grade energy of modern society people.But the calorific value of LNG is lower than the calorific value of LPG, and the effect of heating is obvious not as LPG.
The utility model content
The purpose of the utility model provides a kind of automobile cylinder cap low pressure casting LNG die heater that acts as a fuel and carry out heating operation applicable to LNG.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of automobile cylinder cap low pressure casting LNG die heater; It is characterized in that: air supply pipe and two side nozzle air supply pipe A connect; Its connection place is positioned at the middle part of nozzle air supply pipe A, between the nozzle air supply pipe A of both sides, is provided with nozzle air supply pipe B, and nozzle air supply pipe A and nozzle air supply pipe B are interconnected; On nozzle air supply pipe A and nozzle air supply pipe B, also be provided with several nozzles.
Preferably, the quantity of described nozzle air supply pipe A and nozzle air supply pipe B is two sections.
Preferably, the caliber of described air supply pipe, nozzle air supply pipe A and nozzle air supply pipe B is 32mm.
Preferably, the diameter of described nozzle is 2.5mm～6.7mm.
Preferably, described air supply pipe end is provided with connecting thread.
Preferably, described air supply pipe, nozzle air supply pipe A, nozzle air supply pipe B and nozzle are fixing through welding.
After the utility model adopts said structure; Owing to adopted adjustment air supply pipe caliber, and carried out the mode of communicating of air feed, guaranteed the air demand of LNG from nozzle air supply pipe stage casing; It is temperature required that the heat that its burning is produced reaches mold heated, thereby reach the effect of low-carbon energy-saving.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
Fig. 1 is the vertical view of the utility model.
Fig. 2 is the front view of the utility model.
Fig. 3 is the left view of the utility model
Among the figure: 1, air supply pipe, 2, nozzle air supply pipe A, 3, nozzle air supply pipe B, 4, nozzle.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of automobile cylinder cap low pressure casting LNG die heater; It is characterized in that: air supply pipe 1 and two side nozzle air supply pipe A2 connect; Its connection place is positioned at the middle part of nozzle air supply pipe A2, between the nozzle air supply pipe A2 of both sides, is provided with nozzle air supply pipe B3, and nozzle air supply pipe A2 and nozzle air supply pipe B3 are interconnected; On nozzle air supply pipe A2 and nozzle air supply pipe B3, also be provided with several nozzles 4.
Preferably, the quantity of described nozzle air supply pipe A2 and nozzle air supply pipe B3 is two sections.
Preferably, the caliber of described air supply pipe 1, nozzle air supply pipe A2 and nozzle air supply pipe B3 is 32mm.
Preferably, the diameter of described nozzle 4 is 2.5mm～6.7mm.
Preferably, described air supply pipe 1 end is provided with connecting thread.
Preferably, described air supply pipe 1, nozzle air supply pipe A2, nozzle air supply pipe B3 and nozzle 4 are fixing through welding.
Operation principle: air supply pipe 1, nozzle air supply pipe A2, nozzle air supply pipe B3 and nozzle 4 are through welding and perforation each other.When LNG gas gets into from air supply pipe 1, and full used pipeline, and finally overflow from nozzle 4, lighting the LNG gas of ejection from nozzle 4, can heat mould.
The above is the preferred implementation of the utility model; Certainly can not limit the interest field of the utility model with this; Should be understood that; For those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection domain of the utility model technical scheme.
