专利汇可以提供Thermal bridge for molding machine专利检索,专利查询,专利分析的服务。并且A thermal bridge for an electrically heated compound molding machine wherein the heat transfer from the molding plug is reflected to a heating assembly through a thermal transfer element or thermal plug. The thermal plug is made of a highly conductive material so that small swings of the die are rapidly reflected to the heating element.,下面是Thermal bridge for molding machine专利的具体信息内容。

1. A thermal bridge for critical temperature areas comprising: a heater means; a heat-removing means; a thermal transfer means having a low thermal conductivity and a high thermal capacity compared to both said heater means and said heat-removing means for conducting heat from said heater means to said heat-removing means to provide a thermal barrier and a heat sink between said heater means and said heatremoving means; a passageway extending at least part way through said thermal transfer means in the direction of thermal flow through said thermal transfer means from said heating means to said heatremoving means; an elongated thermal conducting means having high thermal conductivity compared to said thermal transfer means in said passageway and extending from said heat-removing means toward said heating means; and a temperature sensing element mounted inside said elongated thermal conducting means near to said heat-removing means whereby when heat is extracted from said heat-removing means to lower the temperature of said heat-removing means, the temperature of the temperature sensitive element is affected in a short time and the temperature of said heater means may be raised to re-supply heat to said thermal transfer means and thus to said heat-removing means.
2. A thermal bridge for critical temperature areas as set forth in claim 1 in which said heater means comprises, at least one resistance means for imparting heat to the rest of said heating means, a highly conductive material surrounding said resistance means and having one surface in intimate contact with said thermal Transfer means whereby heat is conducted from said heating means to said thermal transfer means.
3. A thermal bridge for critical temperature areas as set forth in claim 1 in which said heat-removing means comprises, a die element for in-place molding of a plastic cap liner.
4. A thermal bridge for critical temperature areas as set forth in claim 1 in which said heat-removing means comprises, a punch made of a heat conductive material and shaped for in-place molding of a plastic cap liner.
5. A thermal bridge for critical temperature areas as set forth in claim 1 in which said thermal transfer means comprises, at least one plate made of a relatively dense material and adapted for intimate contact on a first side with said heating means and on a second side with said heat-removing means.
6. A thermal bridge for critical temperature areas as set forth in claim 1 in which said elongated thermal conducting means comprises, a cylindrical member having a longitudinal axis, a first and second somewhat flared end, a first slot in said first flared end and extending along said longitudinal axis about half-way up the length of said cylindrical member, a second slot at right angles to said first slot and extending about half-way along said longitudinal axis of said cylindrical member, a passageway extending along the longitudinal axis of said cylindrical member from said first end to near said second end whereby a temperature sensitive means may be inserted to near said second end.
7. A thermal bridge for critical temperature areas as set forth in claim 6 in which said elongated thermal conducting means further comprises, a slot in said first end to accommodate an electrical lead to said temperature sensitive means.
8. A thermal bridge for critical temperature areas as set forth in claim 7 in which said thermal transfer means further comprises, a channelway in a surface of said thermal transfer means for an electrical lead to said temperature sensitive means.
9. A thermal bridge for critical temperature areas as set forth in claim 1 in which said elongated thermal conducting means comprises, an elongated cylindrical plug fitting snugly into said passageway in said heat transfer means.
10. A thermal bridge for critical temperature areas as set forth in claim 6 in which said cylindrical member comprises: an elongated element fitting snugly into said passageway in said thermal transfer means.
11. A thermal bridge for critical temperature areas comprising: a heater means; a heat-removing means; a thermal transfer means having a high thermal capacity compared to both said heater means and said heat-removing means for conducting heat from said heater means to said heat-removing means; a passageway extending at least part way through said thermal transfer means in the direction of thermal flow through said thermal transfer means from said heating means to said heat-removing means; an elongated thermal conducting means having high thermal conductivity compared to said thermal transfer means fitting snugly in said passageway and extending from said heat-removing means toward said heating means; and a temperature sensing element mounted inside said elongated thermal conducting means near to said heat-removing means whereby when heat is extracted from said heat-removing means to lower the temperature of said heat-removing means, the temperature of the temperature sensitive element is affected in a short time and the temperature of said heater means may be raised to resupply heat to said thermal transfer means and thus to said heat-removing means.
