Abstract
Description
Technical Field
[0001] The utility model relates to a sole pressing machine, in particular to a sole pressing die set of the sole pressing machine. Background Art
[0002] The sole pressing machine of the prior art generally has the following operation process when pressing the sole of cold-adhesive shoes: when the sole and the shoe body sleeved on the shoe bolt are transmitted together into the sole pressing mold cavity of the sole pressing mold group, the sole pressing mold group moves upward as a whole, so that the front and rear top pressure heads of the sole pressing machine press and position the shoe body on the shoe bolt, and after pressing and positioning, the front and rear pressing modules move relatively close to each other, and the relative close movement of the front and rear pressing modules is driven by the same motor, and the left and right pressing modules also move relatively close to each other, and together squeeze and press the periphery of the sole and the corresponding part of the shoe body, so that the joint parts of the two coated with glue are firmly bonded. However, in actual production, the sole and the shoe body transmitted to the sole pressing mold group are often not transmitted in place, that is, there is a transmission position error. In this way, when the front and rear pressing modules press the sole, since the positions of the sole and the shoe body have been pressed and positioned by the top pressing head and cannot be moved, the front and rear pressing modules have different pressing forces on the periphery of the sole. If the front pressing module contacts the sole first, the pressing force of the rear pressing module will be insufficient. If the rear pressing module contacts the sole first, the pressing force of the front pressing module will be insufficient. As a result, the quality of the sole pressing is not up to standard, affecting the quality of the shoes, and also seriously affecting the production speed of the sole pressing. Summary of the invention
[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a sole pressing module which can ensure the quality of sole pressing even when the sole is not delivered in place, better meet production requirements, have a simple structure and improve work efficiency.
[0004] In order to solve the above technical problems, the first technical solution adopted by the utility model is:
[0005] The sole pressing mold group includes front, rear, left and right pressing modules arranged on the pressing mold base, and the front, rear, left and right pressing modules jointly surround the sole pressing mold cavity. The characteristics are: the front pressing module is connected to the front slider, and the rear pressing module is connected to the rear slider. The front and rear sliders are pushed by the transmission parts to perform reverse movements of approaching and moving away from each other. The transmission parts are installed on the floating seat, and the floating seat is set to float forward and backward.
[0006] The transmission member is a gear, which is rotatably arranged on the floating seat through a gear shaft, and a first rack and a second rack are meshed on both sides of the gear, the first rack is connected to the front slider, and the second rack is connected to the rear slider.
[0007] The rotation of the gear is driven by a servo motor or a hydraulic motor, and the servo motor or the hydraulic motor is installed on the floating seat.
[0008] The floating seat is positioned and supported by an elastic device.
[0009] The elastic device is a spring or a gas spring. The spring or gas spring is provided with two groups, front and rear, which respectively abut against the floating seat from the front and rear sides of the floating seat.
[0010] The elastic device is a cylinder, and the cylinder is provided with two groups, front and rear, which respectively abut against the floating seat from the front and rear sides of the floating seat.
[0011] The elastic device is a combination of a cylinder and a spring, and the cylinder and the spring abut against the floating seat from the front and rear sides of the floating seat respectively.
[0012] The movement of the front slide block, the rear slide block and the floating seat is guided by a longitudinal guide rail, and the longitudinal guide rail is fixedly installed on the pressing mold seat.
[0013] When the sole pressing mold group adopts the above technical solution, when the sole of the cold-glued shoe is pressed, when the sole and the shoe body sleeved on the shoe bolt are transmitted together to the sole pressing mold cavity of the sole pressing mold group, the sole pressing mold group moves upward as a whole, so that the front and rear top pressure heads of the sole pressing machine press and position the shoe body on the shoe bolt. After pressing and positioning, the front and rear pressing modules are driven by the same motor to move relatively close to each other, and the left and right pressing modules are driven by their respective hydraulic cylinders to move relatively close to each other, and jointly squeeze the periphery of the sole and the corresponding part of the shoe body. Pressing makes the joint parts of the two coated with glue firmly bonded; in the above process, if there is a position error between the sole and the shoe body transmitted to the sole pressing module, the floating seat will make corresponding compensation movements. When the front pressing module contacts the sole first, the floating seat will be appropriately offset backwards for position compensation to ensure that the pressing force of the front and rear pressing modules is the same to achieve balance; when the rear pressing module contacts the sole first, the floating seat will be appropriately offset forwards for position compensation to ensure that the pressing force of the front and rear pressing modules is the same to achieve balance. In this way, the utility model can reliably guarantee the quality of sole pressing when the sole is not transmitted in place, better meet production requirements, improve work efficiency, and have a simple structure.
