Abstract
The utility model provides a self-heating mould which is characterized in that the mould is provided with a hollow cavity filled with liquid medium and provide with a heating pipe. With easy temperature control and convenient maintenance, the utility model can maintain the temperature homogeneity for some moulds with high requirements for heating temperature homogeneity.
Description
The utility model belong to a kind of can inner heated mold.
The mould of the industrial application particularly mould of plastics and macromolecular material needs to heat sometimes, so that moulded parts can be shaped better.Original heating mould generally adopts the direct-fired mode of electrode, is about to heating tube and bends to U type or S type, is packed tightly from the outside by mould then.This mode of heating of taking direct heating mould, it is even to exist temperature distributing disproportionation, shortcomings such as heating tube breakdown maintenance inconvenience.
The purpose of this utility model is to provide a kind of novel heating mould, makes some can keep temperature even to the high mould of heating-up temperature uniformity requirement, and is convenient to maintenance, easy control of temperature.
To achieve these goals, feature of the present utility model is to adopt the hollow die cavity, is marked with liquid medium in the die cavity, and heating tube is arranged.With heating tube liquid medium is heated, thereby the indirect mould makes die surface keep temperature even.
A tracheae that promotes medium circulation can be set in the mould.
Liquid medium is water or oil.
For conveniently using and keeping in repair, heating tube adopts the bar type straight tube, its TOE, and the other end inserts in the hollow die cavity, by screw thread it is fixed tightly in the mould side.
Liquid injection port and liquid outlet are arranged on the mould, and switching on and off of temperature sensor and temperature controller control heating tube power supply arranged.
Advantage of the present utility model is: 1, by heat medium indirect mould, temperature is easy to control, good uniformity; 2, adopt compressed air to impel medium to accelerate to flow, quick heating is heated evenly; 3, adopt bar type heating tube and hollow type cavity mould, be convenient to maintenance, save material, reduce cost.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is a heated mould working state figure of the present utility model.
(1) heats main mould; (2) clamping; (3) moulded parts; (4) heating tube; (5) temperature sensor; (6) medium graduation apparatus; (7) medium; (8) die face; (9) liquid injection port; (10) compressed air input pipe; (11) automatic temperature control instrument table; (12) liquid outlet.
Embodiment: heat on the main mould (1) at a cuboid, from liquid injection port (9) to the heating main mould (1) the hollow die cavity in water filling (7) to appropriate amount, connect power supply and add hot water, feed compressed air from compressed air input pipe (10) again, promote the circulation of water, after water temperature reaches automatic temperature control instrument table (11) defined temperature, automatic temperature control instrument table (11) auto-action, stop heating, at this moment, mould can be devoted oneself to work.
After after a while, when keeping in repair, heating tube (4) can be screwed off from the mould side heating tube (4) as need, keep in repair.
Claims (5)
1, a kind of from heating mould, it is characterized in that described mould has the hollow die cavity, be marked with liquid medium in the hollow die cavity, and heating tube is arranged.
2, described according to claim 1 from heating mould, it is characterized in that can being provided with in the mould tracheae that promotes medium circulation.
3, described according to claim 1 from heating mould, it is characterized in that the liquid medium in the mold cavity is water or oil.
4, according to claim 1 from heating mould, it is characterized in that adopting the bar type heating tube, be fixed in the mould side by being threaded.
