Abstract
The utility model provides a curing agent quantifying machine which has a simple structure, can be used for accurately and quantitatively adding a curing agent, needs low human input, and has high production automation degree. The curing agent quantifying machine comprises an outer barrel, and is characterized in that a feeding tube is connected at the top of the outer barrel, a quantifying cylinder below the feeding tube is arranged in the outer barrel, the quantifying cylinder is connected with a gravity sensor which is installed on a bearing steel channel of the inner wall of the outer barrel, a blanking hopper is connected at the lower end of the quantifying cylinder, a valve is installed at the discharge port of the blanking hopper, and the sensor and the valve are in electric control connection.
Description
Technical field
The utility model relates to quantitative mechanical technical field, is specially curing agent quantitative machine.
Background technology
Precoated sand, sand grain surface is covered with molding sand or the core of one deck hard resin film before moulding, and it is roughing sand that precoated sand mainly adopts the selected natural siliceous sand of high-quality, and adds novolac resin, and curing agent, lubricant, reinforcing agent etc. are raw material.Precoated sand moulding is used in the intricate casting that dimension precision requirement is higher, one of optimum shaping materials such as automobile, tractor, hydraulic part, along with the development of domestic and international machinery industry especially automobile industry, more and more higher to casting quality requirement, the application that mould covers sand is more and more extensive.
While adopting mixed precoated sand processed of hot method technique, first roughing sand is heated equably, subsequently warmed-up roughing sand and hard resin are added in puddle mixer and are mixed, resin remains on sand grains and envelopes sand grains after melting.In next stage, the Wu Luotuo par solution as curing agent is added wherein, how much meetings that curing agent adds affect the quality of precoated sand manufacture shell mould, core, the excessive meeting of curing agent causes veiny crackle in shell mould core, curing agent added that I haven't seen you for ages causes shell mould, core distortion, therefore add appropriate curing agent while guaranteeing each sand processed, is necessary very much.
Utility model content
For the problems referred to above, the utility model provides curing agent quantitative machine, and it is simple in structure, adds curing agent quantitatively accurate, and human input is low, and production automation degree is high.
Its technical scheme is such: it comprises outer barrel, it is characterized in that: described outer barrel top is connected with feed pipe, in outer barrel, corresponding described feed pipe below be provided with quantitation tube, on described quantitation tube, be connected with gravity sensor, described sensor gravity is arranged on the load-bearing channel-section steel of described outer barrel inwall, the lower end of described quantitation tube is connected with material-falling hopper, and the discharging opening place of described material-falling hopper is provided with valve, and described sensor and described valve electricly connect.
It is further characterized in that: described valve is pneumatic ball valve;
On the sidewall of outer barrel, be provided with safety door.
The beneficial effects of the utility model are: curing agent enters quantitation tube from feed pipe, after sensor sensing reaches certain amount to the curing agent in quantitation tube, valve opening curing agent solution flows out from discharging opening, it is simple in structure, curing agent adds quantitatively accurately, the end product quality of having guaranteed precoated sand, human input is low, and production automation degree is high.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks schematic diagram;
Fig. 2 is schematic side view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
See Fig. 1 to Fig. 2, the utility model comprises outer barrel 1, outer barrel 1 top is connected with feed pipe 2, in outer barrel 1, corresponding feed pipe 2 below be provided with quantitation tube 3, quantitation tube 3 is connected with gravity sensor 4, gravity sensor 4 is fixed on the load-bearing channel-section steel 5 of outer barrel 1 inwall, the lower end of quantitation tube 3 is connected with material-falling hopper 6, the discharging opening place of material-falling hopper 6 is provided with pneumatic ball valve 7, and gravity sensor 4 and pneumatic ball valve 7 electricly connect, and are provided with safety door 8 on the sidewall of outer barrel 1.
Curing agent solution enters quantitation tube 3 from feed pipe 2, after sensor sensing reaches certain weight to the curing agent solution in quantitation tube 3, pneumatic ball valve is opened, curing agent solution flows out from the discharging opening of material-falling hopper 6, it is simple in structure, and curing agent adds quantitatively accurately, has guaranteed the end product quality of precoated sand, human input is low, and production automation degree is high; The safety door 8 arranging on the sidewall of outer barrel 1 is convenient to safeguard in time and cleaning equipment.
