[0002] The guide device for injection molds with a rotary guide structure refers to a guide component used in the injection mold to ensure the correct positioning and guiding of the mold during the injection molding process. The function of the guide device for injection molds with a rotary guide structure is to ensure the accurate positioning and guiding of the mold during the injection molding process to ensure the quality and dimensional accuracy of the product. It can withstand the high pressure and high temperature during the injection molding process and has the characteristics of wear resistance, corrosion resistance and high temperature resistance.

[0003] Patent number CN217414726U discloses a guide device for injection molds, including an upper mold, the bottom of the upper mold is movably sleeved with the lower mold, the top of the upper mold is provided with a pressure block positioning groove, the inside of the pressure block positioning groove is provided with a pressure block fixing hole, the top of the upper mold is fixedly provided with a raw material injection port, the bottom of the upper mold is provided with a guide column groove, the bottom of the upper mold is provided with an upper mold groove, and the inside of the guide column groove is fixedly sleeved with a guide column. In the above scheme, the upper and lower molds are constantly opened and closed, and the guide column and the guide sleeve are prone to wear and deformation. At this time, the ball bearing is used, and the lubricant is automatically replenished quantitatively during operation, which reduces wear, improves service life, and ensures processing accuracy; in the above scheme, the stroke of the press is difficult to control, and the collision of the upper and lower molds is likely to cause deformation of the corners of the mold groove, thereby affecting the positioning accuracy, and then affecting the injection molding accuracy. At this time, the closed piston is used in conjunction with the buffer spring for buffering to avoid deformation of the corners of the mold groove and ensure processing accuracy.

[0004] However, the current guide device for injection molds has the following problems: when the guide device for injection molds is in use, the opening and closing of the injection mold is prone to cause gaps when the guide device for injection molds is guiding, which leads to the problem of glue overflow due to gaps when the guide device for injection molds is in use.

[0052] The blowing and floating device 8 is arranged on the top surface of the rotating device 5, and the blowing and floating device 8 includes an L-shaped support plate 81, a round shell 82, a servo motor 83 and a fan 84. The L-shaped support plate 81 is fixed on the top surface of the inner part of the square casing 51, and the square casing 51 drives the L-shaped support plate 81 to move forward. The L-shaped support plate 81 is arranged in the middle of the front of the upper template 3, and the round shell 82 is fixed on the inner wall of the L-shaped support plate 81. The L-shaped support plate 81 drives the round shell 82 to move forward. The round shell 82 is arranged above the upper template 3, and the servo motor 83 is fixed at the top of the inner part of the round shell 82. The round shell 82 drives the servo motor 83 to move forward. The servo motor 83 shaft passes through and is rotatably installed at the bottom end of the inner part of the round shell 82. The fan 84 is fixed on the bottom surface of the servo motor 83 shaft. The servo motor 83 shaft drives the fan 84 to rotate forward. The fan 84 is arranged below the round shell 82. The fan 84 rotates forward to blow the ejected product downward, thereby preventing the product in the guide device for the injection mold from being stuck in the equipment.

[0053] The blowing device 8 also includes a circular ring 85, a circular filter screen 86 and four chamfered pieces 87. The circular ring 85 is fixed on the inner back of the L-shaped support plate 81, and the L-shaped support plate 81 supports the circular ring 85. The circular ring 85 is arranged on the outer wall of the fan 84. The circular filter screen 86 is fixed on the bottom surface of the circular ring 85. The circular ring 85 supports the circular filter screen 86. The four chamfered pieces 87 are respectively fixed on the outer wall of the fan 84. The four chamfered pieces 87 are respectively arranged on the top of the inner part of the circular filter screen 86. The fan 84 drives the chamfered pieces 87 to rotate forward, and the chamfered pieces 87 rotate forward to scrape off the impurities accumulated in the holes of the circular filter screen 86, thereby avoiding insufficient wind force when the injection mold guide device blows the molded product downward.

[0054] When the circular strip plate 61 drives the square pad 62 to move forward, the square pad 62 drives the strip push-pull plate 71 to move forward, the strip push-pull plate 71 drives the horizontal plate 72 to move forward, and the horizontal plate 72 drives the U-shaped limiting plate 73 to move forward. When the circular top plate 66 ejects the molded product, the molded product falls downward, and the U-shaped limiting plate 73 limits the position where the molded product falls downward, preventing the position where the molded product falls from being offset, thereby avoiding the problem of inconvenience in collecting the product caused by the drop offset when the injection mold uses the guide device to eject the molded product. When the plate 71 drives the cross plate 72 to move forward, the cross plate 72 drives the U-shaped track plate 74 to move forward, and the semi-arc block 75 supports the rubber roller 76. The rubber roller 76 rolls in the slide groove of the U-shaped track plate 74. Under the action of friction, the rubber roller 76 allows the U-shaped track plate 74 to move forward more smoothly. The rubber roller 76 supports the U-shaped track plate 74, and the U-shaped track plate 74 supports the cross plate 72 to prevent the cross plate 72 from shaking when driving the U-shaped limit plate 73 to move forward, thereby avoiding the problem of product damage caused by the shaking of the U-shaped limit plate 73 when the injection mold uses the guide device to eject the product.

[0055] When the square casing 51 moves forward, the square casing 51 drives the L-shaped support plate 81 to move forward, the L-shaped support plate 81 drives the round shell 82 to move forward, and the round shell 82 drives the servo motor 83 to move forward. The staff starts the servo motor 83 through the electric wire, and the servo motor 83 shaft starts to rotate forward. The servo motor 83 shaft drives the fan 84 to rotate forward. The fan 84 rotates forward to blow the ejected product downward to prevent the molded product from being stuck between the lower module 1 and the upper template 3, thereby avoiding the product in the guide device for the injection mold from being stuck in the equipment. When the servo motor 83 shaft drives the fan 84 to rotate forward, the L-shaped support plate 81 supports the circular ring 85, and the circular ring 85 supports the circular filter screen 86. The fan 84 drives the chamfered piece 87 to rotate forward. The chamfered piece 87 rotates forward to scrape off the impurities accumulated in the holes of the circular filter screen 86, thereby preventing the air volume of the fan 84 from decreasing, thereby avoiding the problem of insufficient wind force for the injection mold guide device to blow the molded product downward.
