Description
Technical field
The present invention relates to valve technology field, be specifically related to a kind of quantitatively hot melting plastic material feeding valve.
Background technique
Traditional valve is commonly used to control the break-make of working fluid, but when the viscosity of some fluent materials is excessive, its flow velocity can very slow, and people use the valve of conventional construction to be difficult to be injected by liquid charging stock fast the position of needs.In the process of carrying out injection moulding production, people usually need first to need in the container of shape by being injected into after plastic molting, but because the plastic viscosity after fusing is very large, make injection moulding very difficult, people are when carrying out injection molding simultaneously, be difficult to control each injection amount, often cause larger waste.
Summary of the invention
For above problem, the invention provides a kind of can by the quantitative hot melting plastic material feeding valve of the plastics fast quantification injection moulding under melted state.
The technical solution adopted for the present invention to solve the technical problems is: this quantitative hot melting plastic material feeding valve comprises valve body, stick harness; Described valve inner is processed with columniform material cavity, and the front end and back end of described material cavity is connected to charging solenoid valve, discharging solenoid valve; Described stick harness is cylindrical shape, and its one end is through the shell wall of valve body, and the shell wall slidable sealing of described stick harness and valve body assembles, and the other end of described stick harness is connected with the telescopic end of cylinder, and described cylinder access high-pressure gas circuit, is equipped with heating module in described material cavity.
As preferably, the number of described stick harness is two or more, and each described stick harness is all to there being a cylinder.
As preferably, each stick harness volume goed deep in described material cavity is all different.
As preferably, described heating module comprises along material cavity axis of orientation to uniform four heating pipes, and described heating pipe uses ceramic material, is designed with heater circuit in heating pipe.
Beneficial effect of the present invention is: this quantitative hot melting plastic material feeding valve is mainly used to carry out quantitative injection moulding to the material under hot melt state, charging solenoid valve and discharging solenoid valve are operationally first opened by this valve, the material cavity of valve body is connected with the equipment of supply hot melt state plastics, so first the inner chamber of valve body is full of, former and later two valves of valve body cut out, heating module in described valve body starts heating, ensures that the plastic raw material in valve body is in melted state always; When starting material feeding, discharging solenoid valve is opened, promote stick harness by cylinder and proceed to valve inner, raw material in valve body is extruded fast, the stick harness volume entered in valve body is fixing simultaneously, therefore its raw material volume extruded also is fixing, so just make this valve complete the shot process of fast quantification, greatly reduce waste, material feeding can be solved simultaneously and cross slow plastic raw material problem inner uneven in temperature.

Embodiment
Below in conjunction with embodiment, the present invention is further described:
As shown in Figure 1, Figure 2 shown in middle embodiment, this quantitative hot melting plastic material feeding valve comprises valve body 1, stick harness 2; Described valve body 1 inside is processed with columniform material cavity 11, and the front end and back end of described material cavity 11 is connected to charging solenoid valve 3, discharging solenoid valve 4; These two valves are one-way valve, are controlled by external electronic equipment.Described stick harness 2 is cylindrical shape, its one end is through the shell wall of valve body 1, and described stick harness 2 assembles with the shell wall slidable sealing of valve body 1, and the other end of described stick harness 2 is connected with the telescopic end of cylinder 5, described cylinder 5 accesses high-pressure gas circuit, is equipped with heating module 6 in described material cavity 11.
This quantitative hot melting plastic material feeding valve is mainly used to carry out quantitative injection moulding to the material under hot melt state, and this valve is mainly used in the hot melt shot process of plastics.Charging solenoid valve 3 and discharging solenoid valve 4 are operationally first opened by this valve, the material cavity 11 of valve body 1 is connected with the equipment of supply hot melt state plastics, the supply arrangement of these hot melting plastic can by plastic melt, and when discharging for the raw material of these melted states provides certain flowing pressure, the inner chamber of valve body 1 is full of.
When being full of raw material in valve body 1, closed by former and later two valves of valve body 1, the heating module in described valve body 1 starts heating, ensures that the plastic raw material in valve body 1 is in melted state always; When starting material feeding, as shown in Figure 2, discharging solenoid valve 4 is opened, promote stick harness 2 by cylinder 5 and proceed to valve body 1 inside, extruded fast by raw material in valve body 1, stick harness 2 volume entered in valve body 1 in material cavity 11 is fixing simultaneously, and therefore its raw material volume extruded also is fixing.Compare the injection moulding process of conventional plastic, utilize stick harness 2 pressing materials, process wants fast a lot, so just makes this valve can complete shot process by fast quantification, greatly reduces waste, can solve material feeding simultaneously and cross slow plastic raw material problem inner uneven in temperature.And after material injection moulding completes, then first discharging solenoid valve 4 cuts out, stick harness 2 is back withdrawn from by the cylinder 5 at this moment controlling again to stretch out, larger suction will be produced like this in the material cavity 11 of valve body 1, thus the plastic raw material of fusing is sucked in valve body 1 fast, improve the feed rate of material.Then above-mentioned discharging process is repeated.
As depicted in figs. 1 and 2, the number of described stick harness 2 is three, and each described stick harness 2 is all to there being a cylinder 5.Each stick harness 2 volume goed deep in described material cavity 11 is all different.The volume that each like this stick harness 2 enters material cavity just can realize different shot capacity, and the user of this equipment can increase the change of shot capacity further by the stick harness 2 entering the different number of material cavity 11, being combined into material cavity 11 and can obtaining multiple different shot capacity by different stick harness 2.
As shown in Figures 2 and 3, described heating module 6 comprises along material cavity axis of orientation to uniform four heating pipes 61, and described heating pipe 61 is distributed in described material cavity 11 and designs along material direction of advance.Described heating pipe 61 uses ceramic material, is designed with heater circuit in heating pipe 61.Stupalith can bear very high temperature, and insulation.Heater circuit liberated heat is delivered in material by the heating pipe 61 of pottery, can keep the melted state of material, ensure its mobility.Described stick harness 2 can pass just between the heating pipe 61 of arrangement.
