Description

Technical Field

[0001] The utility model relates to shoe-making equipment, in particular to a sole forming mould. Background Art

[0002] A sole molding mold is a device used to form the sole of a shoe. It typically consists of a forming die, a punch, and a side mold. Polyurethane is first poured into the die, and then the punch is pressed into the die to form the sole. Polyurethane is then poured again into the die (on top of the sole). The side mold and the shoe last, which holds the upper, are then rotated to press the upper onto the sole in the die. This completes the bonding of the upper and sole. However, currently, this rotation of the side mold and last is laborious and manual. Summary of the Invention

[0004] This automatic opening and closing sole forming mold includes a support, a forming die, a forming punch and a shoe last seat; the forming die is fixedly mounted on the support, the forming punch is mounted on a flip seat, the flip seat is rotatably mounted on the support, and the forming punch and the forming die can be clamped; the shoe last seat is located on one side of the forming die, and two openable side panels are hinged on the shoe last seat, and the side panels are connected to the side molds, and it is characterized in that: a transmission support is mounted on the support, and a rotatable transmission shaft is mounted on the transmission support, the transmission shaft is connected to the inner side panel, and the transmission shaft is in transmission connection with an opening and closing power source, and the opening and closing power source can drive the side panels to rotate and place the side molds above the forming die.

[0005] The shoe last seat is provided with a shoe last chuck for clamping the shoe last. The shoe last seat is connected with a push rod, and a push wheel is installed on the push rod. The push wheel can be pressed against the upper part of the shoe last.

[0006] A rotatable locking hook is installed on the support, and a roller is connected to the outer side plate. When the side mold is above the forming die, the locking hook can hook the roller.

[0007] One end of the transmission shaft is connected to a gear, the opening and closing power source is a cylinder, the telescopic rod of the cylinder is connected to a rack, and the rack is meshed with the gear.

[0008] The transmission support is connected with an I-shaped wheel, the rack is located between the I-shaped wheel and the gear, and the rack is located in the annular groove of the I-shaped wheel.

[0009] According to the automatic opening and closing sole forming mold provided by the utility model, the side mold can be automatically turned up through the driving of the opening and closing power source, thereby improving the degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figure 1 and Figure 2 As shown, this automatic opening and closing sole forming mold includes a support 1, a forming die 2, a forming punch 3 and a shoe last seat 5 (the shoe last seat 5 is used to install the shoe last 6, and the shoe upper is sleeved on the shoe last 6); wherein, the forming die 2 is fixedly mounted on the support 1, and the forming punch 3 is mounted on the flip seat 30, and the flip seat 30 is rotatably mounted on the support 1. When the flip seat 30 is flipped downward, the forming punch 3 can be molded with the forming die 2, so that the sole can be formed. The shoe last seat 5 is located on one side of the forming die 2. Two openable side panels 50 are hingedly connected to the shoe last seat 5 (the two side panels 50 are opened like two doors, making it easier for the shoe last 6 to enter and be placed). The side mold 4 is connected to the side panels 50. In order to enable the side mold 4 to rotate automatically, a transmission support 10 is installed on the support 1. The transmission support 10 is equipped with a rotatable transmission shaft 7. The transmission shaft 7 is connected to the inner side panel 50 and is in transmission connection with the opening and closing power source 9. During operation, the opening and closing power source 9 drives the transmission shaft 7 to rotate, and the transmission shaft 7 rotates with the side panel 50 and the shoe last seat 5, so that the side mold 4 and the shoe last 6 can be placed above the forming die 2. With this structure, there is no need for manual lifting, which greatly reduces the labor intensity of workers and improves production efficiency.

[0014] like Figure 3As shown, the shoe last seat 5 is provided with a shoe last chuck 60 for clamping the shoe last 6 (the shoe last chuck is the existing technology, and the specific structure is that the connection of the shoe last can be clamped by the action of two hinged clamps driven by a cylinder). The shoe last chuck 60 is located directly below the root of the shoe last 6. Therefore, the shoe last chuck 60 will provide better support for the root of the shoe last 6, but the support for the last of the shoe last 6 is poor. When the shoe last 6 is pressed into the forming die 2, the entire bottom surface of the shoe last 6 will be subjected to force. Since the support for the last of the shoe last 6 is poor, the pressure applied will also become worse, which will affect the molding of the sole or the bonding between the sole and the upper. Therefore, the present invention has a push rod 8 connected to the shoe last seat, and a push wheel 80 is installed on the push rod 8, which can be pressed against the upper part of the shoe last 6. Through this structure, the entire bottom surface of the shoe last 6 can be subjected to greater pressure, thereby achieving better sole molding effect and sole adhesion.

[0015] In order to ensure that the shoe last 6, the side mold 4 and the forming die 2 can be firmly clamped, as shown in FIG. Figure 1 As shown, a rotatable lock hook 11 is installed on the support 1, as shown in FIG. Figure 2 As shown, a roller 51 is connected to the outer side plate 50. When the side mold 4 is above the forming die 2, the locking hook 11 is hooked onto the roller 51 by manual or power drive, so that the shoe last 6, the side mold 4 and the forming die 2 can be firmly molded.

[0016] In order to drive the transmission shaft 7 to rotate, as Figure 2 As shown, a gear 91 is connected to one end of the transmission shaft 7, and the opening and closing power source 9 is a cylinder. The telescopic rod of the cylinder is connected to a rack 90, which meshes with the gear 91. When the telescopic rod of the cylinder is extended or retracted, it drives the rack 90 to move up and down, and the rack 90 in turn drives the gear 91 to rotate, so that the transmission shaft 7 rotates, thereby driving the shoe last 6 and the side mold 4 to flip.

[0017] Finally, it is worth mentioning that in order to keep the rack 90 in the vertical direction, as shown in FIG. Figure 2 As shown, the present invention has an I-shaped wheel 92 connected to the transmission support 10, and the rack 90 is located between the I-shaped wheel 92 and the gear 91, so that the rack 90 is restricted to the left and right. In addition, the rack 90 is located in the annular groove of the I-shaped wheel 92, so that the rack 90 is restricted to the front and back, thereby ensuring that the rack 90 only maintains up and down movement in the vertical direction, thereby improving the transmission stability of the rack 90.
