D, with injection machine by injection hole 17, advance hole 16 injection moulding in treating injection molding cavity 13, form the skin 2 that is combined into one with strengthening core 3 in the outside of strengthening core 3;
E, the demoulding, and the cutting bottom reaches the predetermined length of handle for tool.
The forming method that has the pole type tool handle of strengthening core of the present invention, an end of the passage 15 that forms between wherein said bottom for the treatment of injection molding cavity 13 and strengthening core 3 and the mold 10,11 joins, and another termination of passage 15 is described enters hole 16.
The forming method that has the pole type tool handle of strengthening core of the present invention, wherein said outer 2 material is thermoplastics type's material.
The forming method that has the pole type tool handle of strengthening core of the present invention, the temperature of wherein said injection moulding is: 180 ℃-220 ℃, pressure is: 80MPa-120MPa, the time remains: 60 seconds-180 seconds.
The forming method that has the pole type tool handle of strengthening core of the present invention, wherein said strengthening core 3 is a pipe fitting, its upper end place is provided with blocking cap 5, inserts support stick when injection moulding in the endoporus of strengthening core 3, extracts support stick during the demoulding of back to be formed out.
The forming method that has the pole type tool handle of strengthening core of the present invention, the length of wherein said handle for tool are 450 millimeters--1500 millimeters, be processed with installing hole 4 at the place, bottom of handle for tool.
The forming method that has the pole type tool handle of strengthening core of the present invention, owing to be provided with strengthening core in elongated rod shape handle inside, and adopt that the injection moulding mode is compound to go out skin, make it have good straightness degree, the advantage that intensity is high, overcome wooden long handle rapid wear, perishable, the waste natural timber shortcoming, long product lifecycle, and appearance does not have injection point, flat appearance, simultaneously this method have technology simple, easy to operate, to the less demanding advantage of production equipment.

The specific embodiment
Shown in Fig. 1,3,5: the length of determining strengthening core 3 earlier, determining of its length should be definite according to the length of the elongated rod shape handle that will produce, total length should be longer than handle total length, promptly leaves certain surplus in the bottom of strengthening core 3, and its bottom from mold 10,11 is stretched out.The material of described strengthening core 3 is fiberglass or natural material or metal material or plastics, so long as can play the effect of gaining in strength all can, select the rod member of thermoset plastic in the present embodiment for use.
Upper end place at strengthening core 3 processes mould hanging hole 1, and mould hanging hole 1 is penetrating.
With injection molding machine of plastic by injection hole 17, advance hole 16 injection moulding in treating injection molding cavity 13, form the skin 2 that is combined into one with strengthening core 3 in the outside of strengthening core 3, as required, can also form in the end and to hold handle 6.
Carry out the demoulding then and take out, and cutting bottom head reaches the design length of handle for tool by strengthening core 3 and the outer 2 elongated rod shape handles that are composited.
As shown in Figure 5: an end for the treatment of the passage 15 that forms between the bottom of injection molding cavity 13 and strengthening core 3 and the mold 10,11 joins, another termination of passage 15 is described enters hole 16, guaranteed that like this injection point is positioned at outside the product, after the demoulding, cutting can cut injection point during bottom, appearance at product does not leave vestige, makes product have smooth exterior surface.
Outer 2 material is elected thermoplastics type's material as, as polyethylene, polypropylene, ABS etc.
Shown in Fig. 2,4: wherein strengthening core 3 also can be pipe fitting, thermoplastic plastic enters the inboard and the pipe fitting distortion itself of strengthening core 3 when preventing injection moulding, upper end place at strengthening core 3 is provided with blocking cap 5, when injection moulding, in the endoporus of strengthening core 3, insert support stick, extract support stick during the demoulding of back to be formed out.
