Therefore, after the above arrangement, the left and right driving devices 3 can be conveniently driven by the host computer 2 to move left and right on the lower computer 1, and synchronously drive the glue injection gun head 46 to move left and right. In addition, since the left and right driving devices 3 are arranged on the host computer 2, but not on the lower computer 1, the left and right driving devices 3 can be well hidden and arranged so that they do not occupy too much volume, so as to reduce the occupied area of ​​the vacuum casting polyurethane sole automatic production equipment.

After the two racks 38 are provided, the gear 35 can rotate along the rack 38 during the rotation process, which can greatly improve the stability of the gear 35, and then ensure the stability of the upper machine 2 when moving. Similarly, the function of the limit groove 37 is also to limit the roller 36 to prevent it from deviating from the preset route, so as to ensure the stability of the upper machine 2 when moving.

[0041] Preferably, a sliding track 49 is provided between the two sides of the movable seat 48 and the upper computer 2, so as to ensure the stability of the movable seat 48 and the glue injection gun head 46 when they move up and down.

[0042] like Figure 1-Figure 3 As shown, the first stirring motor 6, the second stirring motor 7 and the third stirring motor 8 are respectively installed on the top of the A glue barrel 41, the B glue barrel 42 and the glue injection gun head 46; a stirring rod for inserting into the inner cavity of the A glue barrel 41 is installed on the output shaft of the first stirring motor 6; a stirring rod for inserting into the inner cavity of the B glue barrel 42 is installed on the output shaft of the second stirring motor 7; and a stirring rod for inserting into the inner cavity of the glue injection gun head 46 is installed on the output shaft of the third stirring motor 8. Specifically, the third stirring motor 8 is installed on the moving seat 48. Through the above arrangement, the materials in the A glue barrel 41, the B glue barrel 42 and the glue injection gun head 46 can be stirred and mixed respectively by using the first stirring motor 6, the second stirring motor 7 and the third stirring motor 8 in combination with their respective stirring rods.

[0043] like Figure 1-Figure 3 As shown, preferably, two A glue barrels 41 and B glue barrels 42 are provided respectively; A glue pump 43 is connected to two A glue barrels 41 respectively through pipelines; B glue pump 44 is connected to two B glue barrels 42 respectively through pipelines. Of course, a control valve can be provided at the outlet position of each A glue barrel 41 and B glue barrel 42 to realize the control of the output of polyurethane material. By providing two A glue barrels 41 and two B glue barrels 42, two A glue barrels 41 and two B glue barrels 42 can be used in turn. For example, when the first A glue barrel 41 and the first B glue barrel 42 simultaneously convey polyurethane material to the glue injection gun head 46, another A glue barrel 41 and another B glue barrel 42 can be loaded by the staff. Of course, during the loading process, the heating temperature control device can be used to heat the glue barrel and the stirring motor can use the stirring rod to stir the material in the glue barrel. At the same time, the first vacuum pump 45 vacuumizes the glue barrel to remove the bubbles of the material in the glue barrel. When the materials in the first A glue barrel 41 and the first B glue barrel 42 are used up, the materials are added again and the above operation is repeated, while the stirring rods and the first vacuum pump 45 of the other A glue barrel 41 and the other B glue barrel 42 are stopped, and then the A glue pump 43 and the B glue pump 44 are used to feed the materials to the glue injection gun head 46.

Therefore, when the turning drive cylinder 55 drives the turning frame 54 to turn, the upper mold 53 can be turned synchronously, that is, the mold opening and closing operations can be realized.

[0045] like Figure 1 , Figure 2 , Figure 6-Figure 8 As shown, in order to facilitate the cleaning of the glue injection gun head 46, the vacuum casting polyurethane sole automated production equipment also includes a cleaning mechanism 9; the cleaning mechanism 9 includes a material receiving barrel 91 located on one side of the glue injection gun head 46 and installed on the upper computer 2 so as to be movable forward and backward, a material receiving barrel driving cylinder 92 installed on the upper computer 2 and used to drive the material receiving barrel 91 to move forward and backward, a cleaning agent barrel 93 installed on the upper computer 2, and a cleaning pump 94 respectively connected to the cleaning agent barrel 93 and the glue injection gun head 46 through pipelines. During use, after the glue injection gun head 46 is stopped, the material receiving barrel 91 is driven by the material receiving barrel driving cylinder 92 to move toward the glue injection gun head 46, so that the material receiving barrel 91 can be moved to the bottom of the glue injection gun head 46, and then the cleaning pump 94 is used to flush the cleaning agent in the cleaning agent barrel 93 into the glue injection gun head 46 for cleaning. In this way, the material receiving barrel 91 can be used to receive the dirty water flushed out of the glue injection gun head 46, thereby completing the cleaning of the glue injection gun head 46 to ensure that there is no residue in the glue injection gun head 46 to avoid affecting subsequent use.

Therefore, when the receiving barrel 91 is driven, the guide wheels 96 can move in the guide bar 95 along the length direction of the guide bar 95, thereby improving the stability of the receiving barrel 91 when it moves, and reducing the resistance of the receiving barrel 91 when it moves, making it easier to be driven.

[0047] Combination Figure 1-Figure 8 , the specific use principle of the utility model is introduced below to facilitate understanding of the utility model:

[0048] First, after corresponding inks are sprayed on multiple pieces of textile fabrics (not shown in the figure), corresponding patterns can be formed on the textile fabrics; then, the staff puts the textile fabrics sprayed with ink into the mold cavity of the lower mold 51 of each mold mechanism 5 in turn, and then controls the flip driving cylinder 55 to close the upper mold 52, and the A glue pump 43 and the B glue pump 44 transport the polyurethane material in the A glue barrel 41 and the B glue barrel 42 to the glue injection gun head 46 and use the third stirring motor 8 to drive the stirring rod to mix; then, under the control of the left and right driving devices 3 and the up and down driving devices, the glue injection gun head 46 is inserted into the glue injection port 56 of the first mold mechanism 5, and then the second vacuum pump 53 is controlled, and the mold cavity between the upper mold 52 and the lower mold 51 is continuously formed with negative pressure under the vacuum of the second vacuum pump 53. When the negative pressure reaches the preset value, the glue injection gun head 46 injects glue into the mold cavity, so that the polyurethane material penetrates the textile fabric until The glue injection gun head 46 stops after the polyurethane material fills the mold cavity; then, the left and right drive devices 3 and the up and down drive devices automatically drive the glue injection gun head 46 to move to the next mold mechanism 5 on which the textile fabric sprayed with ink is placed and insert it into the corresponding glue injection port 56, and then repeat the above-mentioned vacuuming and glue injection operations, so that the glue injection gun head 46 can automatically inject glue into each mold mechanism 5 in turn; then, while the glue injection gun head 46 continues to inject glue into the rear mold mechanism 5, the polyurethane on the textile fabric in the front mold mechanism 5 after being injected with glue will gradually take shape, and then the staff can open the mold mechanisms 5 from front to back in turn, take out the textile fabric with polyurethane formed on all sides, put in the new textile fabric sprayed with ink, and then close the mold, and finally continue to perform vacuuming and glue injection operations, and the above-mentioned process is repeated continuously, so that one staff member can realize the automated production operation of multiple soles per round. Since the textile fabric after removal will clearly show the ink pattern, it only needs to be cut accordingly to form a complete polyurethane sole, and finally the sole is fixed to the corresponding position of the bottom of the shoe. Of course, when you want to clean the glue injection gun head 46 at the end, you can refer to the description above, and no further details will be given here.

[0049] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
