Abstract
The invention 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 present invention relates to quantitative mechanical technical field, be specially a kind of curing agent quantitative machine.
Background technology
Precoated sand, namely sand grain surface is covered with molding sand or the core of one deck hard resin film before moulding, and precoated sand mainly adopts the selected natural siliceous sand of high-quality to be roughing sand, and adds novolac resin, and curing agent, lubricant, reinforcing agent etc. are raw material.Precoated sand moulding is used in the higher intricate casting of dimension precision requirement, one of optimum shaping materials such as automobile, tractor, hydraulic part, along with the development of domestic and international machinery industry especially automobile industry, require more and more higher to casting quality, the application that mould covers sand is more and more extensive.
When adopting the mixed precoated sand processed of hot method technique, first roughing sand is heated equably, warmed-up roughing sand and hard resin are added in puddle mixer mix subsequently, to remain in after resin melting on sand grains and to envelope sand grains.In next stage, the Wu Luotuo par solution as curing agent is added wherein, curing agent add number can affect precoated sand manufacture shell mould, core quality, 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 to be out of shape, therefore added appropriate curing agent when ensureing each sand processed and be necessary very much.
Summary of the invention
For the problems referred to above, the invention provides a kind of curing agent quantitative machine, its structure is simple, and add curing agent quantitatively accurate, 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, the below of corresponding described feed pipe is provided with quantitation tube, described quantitation tube is connected with gravity sensor, described sensor gravity safety is contained 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 discharge outlet 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;
The sidewall of outer barrel is provided with safety door.
The invention has the beneficial effects as follows: 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, its structure is simple, curing agent adds quantitatively accurately, ensure that the end product quality of precoated sand, human input is low, and production automation degree is high.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present invention;
Fig. 2 is schematic side view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further:
See Fig. 1 to Fig. 2, the present invention includes outer barrel 1, outer barrel 1 top is connected with feed pipe 2, in outer barrel 1, the below of corresponding feed pipe 2 is provided with quantitation tube 3, and quantitation tube 3 is connected with gravity sensor 4, and 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 discharge outlet of material-falling hopper 6 is provided with pneumatic ball valve 7, and gravity sensor 4 and pneumatic ball valve 7 electricly connect, and the sidewall of outer barrel 1 are provided with safety door 8.
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, its structure is simple, and curing agent adds quantitatively accurately, ensure that the end product quality of precoated sand, human input is low, and production automation degree is high; The safety door 8 that the sidewall of outer barrel 1 is arranged is convenient to safeguard in time and cleaning equipment.
