Said injection tube one end is connected with injection head; Be provided with the valve body that is connected with its slipper seal in the said injection tube; Said rifle body is arranged at the top of the injection tube other end; Rifle body one side is connected through the upper end of connecting plate and pikestaff, is in same horizontal position with injection tube in the said pikestaff and is provided with spring;
Said linkage comprises hinged trigger of intersection and connecting rod, and the upper end and the connecting plate of said trigger are hinged; Said connecting rod one end is connected with valve body, and an end is connected with spring.
Above-mentioned injection head is a bullet-shaped, and its external diameter is greater than the injection tube external diameter, and the injection head set inside has one way stop peturn valve.This injection head be arranged on when injection can and mold injects mouth auto lock, material leaks outside when preventing to inject; Being provided with of one way stop peturn valve can make injection stop immediately, can not leak outside.
Be provided with reservoir in the above-mentioned rifle body, the bottom of said reservoir is an inlet.Being provided with of reservoir can make two kinds of material mixing even, and can realize continuous charging.
Above-mentioned injection tube is the two parts that removably connect, and injection tube is provided with detachable end near an end of pikestaff, and rifle body, pikestaff and connecting plate adopt nut to be connected respectively.Be convenient to dismounting and cleaning, prevent to stop up and cause damage of product, guarantee properties of product.
With respect to prior art, the advantage and the effect of the utility model are:
1, adopt linkage, simple in structure, easy to operate.
2, ability mold injects mouth auto lock when injection, material leaks outside when preventing to inject; The injection port of injection head and mould can in time be sealed automatically when stopping to inject, and prevents that material from leaking outside.
3, be convenient to dismounting and cleaning, prevent to stop up and cause damage of product, guarantee properties of product, also avoid resin solidification to cause injection device to scrap.
4, can make two kinds of material mixing even, and can realize continuous charging.
