Abstract
A mold heating mechanism is used in a mold. The mold comprises a male mold core and a female mold core. The mold heating mechanism comprises a plurality of steam channels and a plurality of electrical heating elements. The plurality of steam channels are arranged in the male mold core or the female mold core or are arranged in the male mold core and the female mold core at the same time. Each steam channel is a cylindrical object. The electrical heating elements are arranged at one side of the steam channels in parallel. Each electrical heating element is a cylindrical object and is made of metal. According to the mold heating mechanism, the electrical heating elements are arranged at one side of the steam channels in rapid heat cycle molding (RHCM), heat is generated by the electrical heating elements in the process of operation and the steam channels are matched so that the mold is heated and the temperature of the mold is rapidly increased to 200 DEG C-400 DEG C. The high mold temperature, needed by a high rigid material, can be reached by the mold heating mechanism.
Description
[technical field]
The utility model relates to a kind of heating-up mechanism, particularly relates to a kind of heating-up mechanism be applied in mould.
[background technology]
RHCM (Rapid Heat Cycle Molding) is the high-speed and high-temperature forming technique, refer to Fig. 1, its generalized section that is prior art, mechanism in the prior art comprises some steam channels 11, this steam channel 11 is located in die 13, and this steam channel 11 is parallel arranges side by side, when mould is heated, pass into high-temperature steam in steam channel 11, this high-temperature steam in order to heating mould with shaped article 12.
Yet, the accessible maximum temperature of existing RHCM technology only has 160 ℃, along with the variation of market to product 12 requirements, product 12 is towards frivolous future development, trending towards the high rigid material that those mechanical strengths are high aspect the selection of material, but the mould temperature that the high rigid material of this class needs when shaped article 12 is very high, apply existing RHCM technology when the high rigid material of this class of moulding, not only in die cavity, there will be the not runny situation of material, and after product 12 moulding, easily occur shortly penetrating, the phenomenon of meat thickness ununiformity, swollen mould and junction undercapacity.
In view of this, be necessary to provide a kind of mould heating-up mechanism in fact, this mould heating-up mechanism can solve the problem that can't reach the needed Gao Mowen of high rigid material existed in prior art.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of mould heating-up mechanism, and this mould heating-up mechanism can solve the above-mentioned problem that can't reach the needed Gao Mowen of high rigid material.
In order to achieve the above object, mould heating-up mechanism of the present utility model, be applied in mould, and this mould comprises a male die core and a mother module core, and this mould heating-up mechanism comprises:
Some steam channels, it is located in male die core or mother module core, or this steam channel is located in male die core and mother module core simultaneously, and this steam channel is column; And
Some heatings, this heating parallel arrangement is in described steam channel one side, and this heating is column, and the material of this heating is metal.
Preferably, the horizontal range between described adjacent two heatings is identical.
Preferably, described heating is electrothermal tube.
Preferably, be provided with the plug hole corresponding with electrothermal tube in described male die core or mother module core, this plugs hole and is provided with ，Gai open end, at least one open end in order to insert plugging in hole of correspondence with it for electrothermal tube.
Preferably, the material of described heating is iron.
With respect to prior art, mould heating-up mechanism of the present utility model, that steam channel one side in RHCM arranges heating, by heating in the course of the work produce heat and with the steam channel incompatible heating mould that matches, make the mould temperature be raised to fast 200～400 ℃, mould heating-up mechanism of the present utility model can reach the needed Gao Mowen of high rigid material.
[accompanying drawing explanation]
Fig. 1 illustrates the generalized section of prior art.
Fig. 2 illustrates the generalized section of the utility model mould heating-up mechanism.
[specific embodiment]
Refer to shown in Fig. 2 the generalized section that wherein Fig. 2 is the utility model mould heating-up mechanism.
Mould heating-up mechanism of the present utility model, be applied in mould, and this mould comprises a male die core (not shown) and a mother module core 103, and in the present embodiment, this mould heating-up mechanism comprises:
Some steam channels 101, it is located in male die core or mother module core 103, or this steam channel 101 is located in male die core and mother module core 103 simultaneously, and in the present embodiment, this steam channel 101 is located in mother module core 103, and this steam channel 101 is column; And
Some heatings 100, consult shown in Fig. 2, and these heating 100 parallel arrangements are in described steam channel 101 1 sides, and this heating 100 is column, and the material of this heating 100 is metal.
In the present embodiment, the horizontal range that two adjacent heatings are 100 is identical.
In the present embodiment, this heating 100 is electrothermal tube.
In the present embodiment, be provided with the plug hole corresponding with electrothermal tube in described male die core or mother module core 103, this plugs hole and is provided with ，Gai open end, at least one open end in order to insert plugging in hole of correspondence with it for electrothermal tube.
In the present embodiment, the material of this heating 100 is iron.
In the present embodiment, please refer to Fig. 2, before the mould matched moulds, mould is heated, pass into high-temperature steam in steam channel 101, after heating 100 energisings, start to be rapidly heated, mould is due to the heat effect that is subject to high-temperature steam and heating 100, and the mould temperature is raised to 200～400 ℃ at short notice fast; Then matched moulds carry out injection moulding, good fluidity and the moulding in die cavity under the mould temperature of described 200～400 ℃ of high rigid material is quick; After injection moulding completes, mould is lowered the temperature, stop passing into high-temperature vapour in steam channel 101, heating 100 stops heating, start to inject cold water in steam channel 101, make mould temperature fast-descending, product 102 moulding complete, and then start injection molding product 102 next time.
With respect to prior art, mould heating-up mechanism of the present utility model, that steam channel 101 1 sides in RHCM arrange heating 100, by heating in the course of the work 100 produce heats and with the steam channel 101 incompatible heating mould that matches, make the mould temperature be raised to fast 200～400 ℃, mould heating-up mechanism of the present utility model can reach the needed Gao Mowen of high rigid material.
