Description

The both-end wax injector

The utility model relates to wax injector, especially a kind of both-end wax injector.

Wax injector is the machine that is used for making wax-pattern, and made wax-pattern is used for foundary industry.Below be the program of making wax-pattern: at first die is put into wax injector and, then wax is injected die, again die is removed from press, at last wax-pattern is taken out from die with its clamping.After assembling in groups, the wax-pattern of making just can obtain the metal casting identical through casting again with the wax-pattern shape.

Existing wax injector is made of fuselage and the casting grain-clamping table, wax storage, casting cylinder, casting flexible pipe, casting mouth, hydraulic power source, the control circuit that are contained on the fuselage, the casting cylinder is made of cylinder barrel and piston and is driven by hydraulic power source, and the casting grain-clamping table is used for clamping wax-pattern press.Under hydraulic power source drove, the wax in the wax storage entered the casting cylinder, drained into the casting flexible pipe from the casting cylinder again, after the casting mouth enters in the die that is clipped on the wax-pattern press, formed wax-pattern.

But this wax injector has only designed a casting mouth, in a working cycles, can only make a wax-pattern, thereby influence production efficiency like this.

In view of above-mentioned, the purpose of this utility model provides a kind of both-end wax injector that once can be made into two wax-patterns.

For reaching this purpose, the utility model adopts following technical scheme: a kind of both-end wax injector, comprise fuselage and be fixed on wax storage, casting cylinder, casting flexible pipe, casting mouth, casting grain-clamping table, hydraulic power source, control circuit on the fuselage, the casting cylinder is made of cylinder barrel and piston and is driven by hydraulic power source, it is characterized in that:

It also comprises the feeding and discharging valve, and the feeding and discharging valve is provided with a charging aperture and two discharging openings, and the both sides of the valve rod of feeding and discharging valve are provided with the groove that communicates with two discharging openings respectively;

Described casting cylinder, casting flexible pipe, casting mouth, casting grain-clamping table are two cover configurations;

The feeding inlet of the bottom of described wax storage and described feeding and discharging valve;

Described feeding and discharging valve communicates with two casting cylinders respectively, and two discharging openings of feeding and discharging valve are connected with described two casting flexible pipes respectively, and the end of these two casting flexible pipes connects described casting mouth respectively, and each casting mouth is respectively by each casting grain-clamping table clamping.

In implementing measure of the present utility model: in the described wax storage agitating device is housed, the primary heater that upper strata wax is heated to melt temperature is equipped with on the top of wax storage, and the secondary heater that wax is heated to softening temperature is equipped with in the bottom.Described primary heater is an electric heater, and described secondary heater is by the hot-water heating system that hot water constituted between the tank body of wax storage and lining, this tank body and the lining.

Two cover casting cylinders of the present utility model, casting flexible pipe, casting mouth, casting grain-clamping table have constituted two cover casting systems, they are by same wax storage supply wax material, and control respectively by a control circuit, two cover casting devices all can be worked independently, and are unaffected mutually.

Because the utility model has adopted two cover casting systems, and the duty of every cover is unaffected mutually, thereby can in a working cycles, make two identical or different wax-patterns independently, not only improve the operating efficiency of equipment, and had the advantage of flexibility.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a top view of the present utility model;

Fig. 3 is the decomposition chart of wax storage;

Fig. 4 is the cutaway view of high pressure casting device.

See also accompanying drawing 1 and Fig. 2.The utility model is a kind of both-end wax injector, it is by fuselage 11 and be fixed on wax storage 16 on the fuselage 11, two casting cylinders 18.1 and 18.2, feeding and discharging valve 44, two casting flexible pipes 13.1 and 13.2, two casting mouths 14.1 and 14.2, two casting grain-clamping tables 12.1 and 12.2, hydraulic power source 15, control circuit are formed, and 20 is the guidance panel of control circuit.

The structure of wax storage 16 as shown in Figure 3, it comprises tank body 25 and agitating device 26 two parts.Wherein: agitating device 26 is made of board-like scraper 28 and drive motors 30.The primary heater 32 that upper strata wax is heated to melt temperature is equipped with on the top of tank body 25, and it is a kind of electric heater.The secondary heater that wax is heated to softening temperature is equipped with in the bottom of tank body 25, and it is that its water temperature regulater 17 is shown among Fig. 1 by the hot-water heating system that hot water constituted between tank body 25 and lining 34, tank body 25 and the lining 34.The heating-up temperature of primary heater 32 can make the wax on upper strata in the tank body 25 melt, and when agitating device 26 stirred wax, primary heater 32 can make the upper epidermis of wax form a liquid sealant like this, entered in the wax when stirring to prevent air.The temperature of secondary heater is low, also under high pressure can become wax-pattern by squeeze note as long as can make the wax that is positioned under the wax liquid layer keep softening.

See also Fig. 4.The casting cylinder 18 that is made of cylinder barrel 42 and piston 46 constitutes high pressure casting device 40 with feeding and discharging valve 44, and piston 46 is driven by hydraulic power source 15 (consulting Fig. 1).Feeding and discharging valve 44 is provided with a charging aperture 45 and two discharging opening (not shown)s, the bottom of wax storage 16 communicates with this charging aperture 45, feeding and discharging valve 44 communicates with two casting cylinders 18.1 and 18.2, valve rod 47 both sides of feeding and discharging valve 44 are provided with the groove that communicates with two discharging openings respectively, two discharging openings of feeding and discharging valve 44 are connected with 13.2 with two casting flexible pipes 13.1 respectively, and the end of these two casting flexible pipes is connected and fixed on two casting mouths 14.1 and 14.2 on the grain-clamping table 12 respectively.

Introduce the course of work of the present utility model below:

After on the casting mouth 14.1 and 14.2 of two casting grain-clamping tables 12.1 and 12.2 die being installed, adjust the pressure and the flow of casting more respectively by hand switch 22.1 and 22.2, through after carrying out corresponding start-up operation on the guidance panel 20, the both-end wax injector is just worked under the control of control circuit automatically, and its process is:

Feeding and discharging valve 44, casting cylinder 18.1 and 18.2 are driven by hydraulic power source 15 does the wax action, and the softening wax in the wax storage 16 just enters in the cylinder body 42 of casting cylinder 18.1 and 18.2 through the charging aperture 45 of feeding and discharging valve 44.After this hydraulic power source 15 drives feeding and discharging valve 44, casting cylinder 18.1 and 18.2 is done the de-waxing action again, so the wax in two cylinder bodies 42 just respectively through the concentrated flow of the valve rod both sides of feeding and discharging valve 44 to two discharging openings, and enter in two dies that are contained in the casting mouth through separately casting flexible pipe 13 and casting mouth 14 respectively.Like this, in a working cycles, just can make two wax-patterns simultaneously.

In the manufacturing process of two wax-patterns, not only pressure separately and flow can be regulated separately, and a cover casting device is respectively arranged, and the duty of every covering device is unaffected mutually, thereby can produce two identical or different wax-patterns simultaneously.
