[0023] Compared with the current plastic dripping equipment with only a single row of plastic dripping heads, this device greatly improves the plastic dripping efficiency. At the same time, the spacing between each group of mounting beams 10 in the plastic dripping head combination 9 can be quickly adjusted according to the size of the mold cavity. In combination with the adjustable automatic clamp 18, this device can be applied to the plastic dripping work of multi-cavity molds of different specifications.

[0024] A laser sensor 15 is disposed on the front side of the mounting crossbeam 10 , and a reflective plate 16 is disposed on the back side of the mounting crossbeam 10 .

[0025] During the adjustment process of the mounting beams 10, the laser sensors 15 on a group of mounting beams 10 perform laser ranging on the reflective plates 16 on a group of mounting beams 10 located in front of them. The cooperation of the laser sensors 15 and the reflective plates 16 assists the through-screw servo motor 13 to move, thereby improving the accuracy of the position adjustment of the mounting beams 10.

[0030] Working principle and use process of the utility model: the device is suitable for the drip molding of multi-cavity drip molding molds, and has the function of drip molding for multiple mold cavities at the same time. Before drip molding, the spacing between the two adjacent groups of mounting beams 10 in front and behind is adjusted according to the size of the multi-cavity mold and the spacing between the front and rear rows of mold cavities. During adjustment, the through-screw servo motor 13 on the inner side of the slider 12 at one end of each mounting beam 10 can be controlled to operate, and the slider 12 is driven to move together with the mounting beam 10 through the transmission between the through-screw servo motor 13 and the screw 11 to adjust the spacing between the mounting beams 10. During the adjustment process, the laser sensor 15 on a group of mounting beams 10 performs laser ranging on the reflective plate 16 on a group of mounting beams 10 located on the front side thereof. The cooperation of the laser sensor 15 and the reflective plate 16 assists the through-screw servo motor 13 to move, thereby improving the accuracy of adjusting the position of the mounting beam 10. After the adjustment is completed, the mold to be dripped can be installed.

After placing the mold on the top of the workbench 17, the first electric cylinder 20 and the second electric cylinder 23 can be controlled to drive the lateral clamping plate 21 and the rear positioning plate 24 to move respectively, clamp the mold, and fix the mold in the middle position of the top of the workbench 17, and then start dripping. The heating and feeding component 3 heats and melts the raw material and then transports the rubber material to the dripping head 14 through a pipeline (not shown in the figure), and drives the hanger 7 to move forward, backward, left, right, up and down through the Z-axis linear drive 4, the Y-axis linear drive 5, and the X-axis second linear drive 6. Each mounting beam 10 is driven to move according to the trajectory set by the plastic dripping program, so that the plastic dripping heads 14 on each mounting beam 10 synchronously drip plastics on each mold cavity of the mold aligned therewith. In summary, compared with the current plastic dripping equipment which only has a single-row plastic dripping head, this device greatly improves the plastic dripping efficiency. At the same time, the spacing between each group of mounting beams 10 in the plastic dripping head combination 9 can be quickly adjusted according to the size of the mold cavity. In combination with the adjustable automatic clamp 18, this device can be suitable for plastic dripping of multi-cavity molds of different specifications.
