Description
Technical field
The utility model relates to injection mold part field, particularly a kind of novel injection mold stopcock.
Background technology
Stopcock is among plastic mold or the cooling of any water channel or heating system, coordinates the metal parts of the effect played about filling according to the required flow direction.The stopcock scope of application: plastic mould, water channel runner cooling system, runner water channel are heated heat-conducting system.
In plastic parts injection moulding process, generally need to design many coolings or heating water route, and traditional injection mold stopcock is undertaken sealing by the expansion of rubber, when water temperature is higher, easily occur drainage, and traditional injection mold stopcock needs design fortune depositing in water head bore, again stopcock is put into wherein, usual stopcock placement location is fixed (as shown in Figure 1), and not easily flexible, service efficiency is low.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of injection mold stopcock, greatly simplify installation procedure, and improves service efficiency.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of injection mold stopcock, it is characterized in that, comprise the sleeve pipe of copper material, the fastening bolt of trapezoidal aluminium material is provided with in described sleeve pipe, described fastening bolt to be trapezoidally formed by connecting by several, and described sleeve pipe is evenly provided with several rubber ring outward, and described each rubber ring faces each trapezoidal edge of going to the bottom in fastening bolt, described fastening bolt inside is provided with setscrew, and described setscrew inside is provided with soft groove.
A kind of injection mold stopcock, it is characterized in that, the material of described sleeve pipe is brass.
A kind of injection mold stopcock, it is characterized in that, described rubber ring is high-temperature resistant rubber circle.
A kind of injection mold stopcock, it is characterized in that, described rubber ring thickness is 0.5-1.5mm.
A kind of injection mold stopcock, it is characterized in that, the material of described groove is rubber.
A kind of injection mold stopcock, it is characterized in that, described groove top is provided with rectangle opening.
Principle of the present utility model is: 1. stopcock of the present utility model utilizes the thermal coefficient of expansion of unlike material, uses being located at inner fastening bolt aluminium (thermal expansion system=23*10 that thermal coefficient of expansion is large
-6/ DEG C), outside sleeve pipe uses copper (thermal expansion system=17.7*10 that thermal coefficient of expansion is larger
-6/ DEG C), copper sleeve is provided with high-temperature resistant rubber circle, when heating up, aluminium matter fastening bolt undergoes rapid expansion, and then drive the expansion of copper sleeve pipe and rubber ring, increase the expansion dynamics of sleeve pipe and rubber ring further; 2. stopcock of the present utility model utilizes copper part expanded by heating principle, copper sleeve is out of shape, thus form interference fit with fortune water hole, can not only water blockoff, more can gas shutoff, invest outer field sealing ring thickness and greatly reduce, during expansion, coordinate copper sleeve to expand, achieve the combination of rubber shutoff and interference seal, efficiency improves greatly.
Usefulness of the present utility model is: 1. at high temperature expansion effect is remarkable, can water blockoff, gas shutoff efficiently; 2. stopcock of the present utility model can be positioned over any position of fortune water, and install simple, service efficiency is high, effective; 3. install and take off convenient and simple, efficient.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
Composition graphs 2, 3 and 4, injection mold stopcock 6 of the present utility model, comprise the sleeve pipe 1 of brass material, the fastening bolt 3 of trapezoidal aluminium material is provided with in described sleeve pipe 1, described fastening bolt 3 to be trapezoidally formed by connecting by 5, described sleeve pipe 1 is outer is evenly provided with 4 rubber rings 2, the thickness of described rubber ring 2 is 0.5mm, described each rubber ring 2 faces each trapezoidal edge of going to the bottom in fastening bolt 3, when high-temperature expansion, going to the bottom expands can drive the further expansion of rubber ring 2, described fastening bolt 3 inside is provided with setscrew 4, described setscrew 4 inside is provided with the groove 5 of quality of rubber materials, described groove 5 top is provided with rectangle opening (not shown), stopcock erecting tools can be coordinated to install efficiently.
Injection mold stopcock 6 of the present utility model, except said structure, its difference is, described rubber ring 2 is silicon rubber loop, can be high temperature resistant, improves service efficiency; Described sleeve pipe 1 material is red metal; The thickness of described rubber ring 2 is 1mm.
Injection mold stopcock 6 of the present utility model, except said structure, its difference is, the thickness of described rubber ring 2 is 1.5mm.
The stopcock erecting tools that the utility model applies to, comprise mounting rod and mounting head, described mounting head cross section is rectangle, can pass freely through the rectangle opening on groove 5 top, described mounting head termination is provided with claw hook, and its claw hook is packed up when not using and is positioned at mounting head termination, launched by the control claw hook of button and draught line during use, form fish hook shape termination, thus clench outside rectangle opening, in order to water pipe is transported in stopcock pull-out.
Injection mold stopcock of the present utility model proves by experiment, and its plugging effect is remarkable, can bear 60kg/cm
2hydraulic pressure, and can be used for the steam of shutoff 150 ~ 200 DEG C, stopcock of the present utility model can be installed on any position of fortune water pipe, effectively can reduce core rod and bore empty processing, improves the processing effect of water route arrangement and pincers worker.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
