Being provided with electrical heating wire bottom installing plate, electrical heating wire is arranged on bottom installing plate by earthenware, electrical heating
Silk S-type distribution bottom installing plate, laterally offers a cooling in the heated aluminum block below heating chamber
Water cavity, cooling water cavity left end is provided with water inlet, and cooling water cavity right-hand member is provided with outlet, in exhaust passage
Being provided with the boss of circulus on medial wall, boss left side is concordant with exhaust passage entrance point.
Going up the replacing of mould body for convenience, the most described projection distinguishes horizontal stroke with offering on the upper mould body of groove
To offering centrage through hole on the same line, being coated with a connecting rod in through hole, connecting rod is by upper mold
Body and heated aluminum block link together, and connecting rod two ends pass respectively at upper mould body left and right sides wall.
Go up the replacing of mould body for convenience, improve and change speed, on the right side of the most described connecting rod, be provided with one piece
For the block preventing connecting rod from moving right, block is fixed on heated aluminum block right side wall.
In order to easy to operate, conservative control cost simultaneously, on the left of the most described connecting rod exposed junction be 300mm～
500mm。
Ibid in order to easy to operate, time saving and energy saving, conservative control cost simultaneously, the most described connecting rod is a diameter of
30mm～50mm.
Compared with prior art, the beneficial effect that the present invention is brought is mainly:
By the present invention, its simple in construction, under heated aluminum block effect, the even heat in heating chamber is led to
Crossing projection to be transferred on mould body, mould body thermally equivalent on it, firing rate is fast, and production efficiency is high,
Easy for installation, simultaneously when batch injection, only need to consider steam vent distribution and charging aperture distribution situation, be not required to
The uniformity of heating to be considered further that, facilitates Design of Dies, it is ensured that the qualification rate of product.At cooling water cavity
Effect under, quickly the upper mould body after injection formed can be lowered the temperature, thus accelerate product
Cooling and shaping.Under the design of boss, facilitate the demoulding of injecting products molding, ensure that injection is protected simultaneously
Pressurize effect during pressure, further increases the product qualification rate when the demoulding.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention is expanded on further.In the following detailed description, the most logical
The mode crossing explanation describes some one exemplary embodiment of the present invention.Undoubtedly, the common skill of this area
Art personnel will be consequently realised that, in the case of without departing from the spirit and scope of the present invention, can use various difference
Mode described embodiment is modified.Therefore, accompanying drawing and description are the most illustrative,
Rather than be used for limiting scope of the claims.
Embodiment one
As shown in Figure 1, Figure 2, Figure 3 shows, for fan leaf electric heating wire type band cool down injection upper mold, including on
Mould body 2, the right lower quadrant of upper mould body 2 has been horizontally disposed with exhaust passage 10, sets on upper mould body 2 top
Being equipped with one piece of heated aluminum block 4 for the heating of upper mould body 2, the upper surface at upper mould body 2 offers downwards
