1. because shooting material of Jet forming machine manages 13 when execution shoots material action, the range controlling mechanism 12 that must rely on its rear provides the one stroke driving force, pipe 13 is not on same horizontal plane with the driving stroke of range controlling mechanism 12 but this shoots material, but shoot material pipe 13 up, its range controlling mechanism 12 below, therefore, when its nozzle 130 that shoots material pipe 13 front ends is subjected to range controlling mechanism 12 to carry out in the matching mechanism of injecting correspondence, the error that will certainly produce slightly elevation angle skew exists, though its error amount still is difficult to see with naked eyes, but get off for a long time to the service life of its board member and the quality that shoots material thereof still having certain influence, still need and wait to improve.

2. in general, shooting material of Jet forming machine manages 13 after using a period of time, based on some factor, for example maintenance, must unload replacing, but at present known shooting material managed conduit 11 length of 13 length much larger than its below, so that the peripheral element of the pipe 13 that must one by one this be shot material all unloads, just replaceable this shoots material and manages 13, obviously has consuming time taking a lot of work and changes the shortcoming of pipe 13 inconvenience that shoot material.

3. present known Jet forming machine, 14 designs of pipe arrangement that its ejecting device 10 is relied on all can only be entangled with in the lump rear at its range controlling mechanism 12 (because of the below of its parallel conduits 11 there is no the space can be for setting so), though the action of pipe arrangement 14 is indispensable setting, but from the production cost angle, the ejecting device of Jet forming machine, its range controlling mechanism 12 is not the rear that is positioned at board entirely, also have plenty of and manage 13 directions near shooting material, therefore, certainly will cause the length of pipeline lengthening of whole pipe arrangement 14, this promptly causes its whole pipe arrangement cost to raise up, and pipeline also seems more disorderly and more unsystematic, and real difficulty accords with the demands of the market, and also has higher production pipe arrangement cost expenditure, be not inconsistent economic benefit, still still need wait to be improved.

In view of this, the utility model at above-mentioned defective and not to the utmost ideal designs structure improved.Main purpose of the present utility model promptly is to provide a kind of ejecting device structure of improved Jet forming machine, can improve the known pipe that shoots material and change defectives such as inconvenience and nozzle skew, two and can save its pipe arrangement cost, can reach the function of the stable using character of high productivity effect.

To achieve these goals, the utility model provides a kind of ejecting device structure of improved Jet forming machine, it is characterized in that including:

One is the guide rod of the upper and lower correspondence in oblique angle, and the two ends of this guide rod are respectively equipped with a forward and backward holder and are supported and fixed on the board of Jet forming machine;

The one stroke controlling organization is to be located on this guide rod, and the bottom also is provided with sliding seat support, and the formed space of the corresponding guide rod of this sliding seat is enough big, can stretch for the pipe arrangement path on the range controlling mechanism and establish; And

One pipe that shoots material, system is controlled by the trip controlling organization, and its pipe diameter length is less than the length of guide rod, and the formed oblique angle of corresponding upper and lower guide rod central point, replacing shoots material when pipe, only need retire range controlling mechanism and can conveniently unload, and because of its pipe that shoots material be the center that is positioned at guide rod, so the stroke that penetrates is stable, and the nozzle of its front end can not produce elevation angle shift phenomenon.
