Description

Technical Field

[0001] The present application relates to the technical field of shoe stretcher manufacturing, and in particular to a shoe stretcher forming mold and a shoe stretcher forming machine. Background Art

[0002] A shoe stretcher is a mold that prevents shoes from deforming. It is also called a shoe last. Before wearing shoes, to ensure their comfort, shoe stretchers are usually used to support the internal space of the shoes so that the space inside the shoes matches the feet and improves comfort. When the shoes are stored daily, shoe stretchers are also used to support the shoes to ensure that their shape is not disturbed.

[0003] At present, the common production process of shoe stretchers is: cardboard beating, die forming, drying, trimming, shaping, and finished products. Die forming is to press the pulp into a forming board through a forming board forming machine. The forming board is connected by several shoe stretcher blanks and edge materials. The surface of the shoe stretcher blank is relatively rough, and it is necessary to drive the shoe stretcher blank mold through a driving device to press the surface of the shoe stretcher blank smooth, and then use a trimming device to cut and separate several shoe stretcher blanks in the forming board. The separated shoe stretcher blank is in the shape of a horizontal plate, and then the shoe stretcher blank is pressed into an arc-shaped finished product through a shoe stretcher forming mold so that the shoe stretcher can support the internal space of the shoe. The shoe stretcher forming mold usually includes an upper mold and a lower mold. The surface of the lower mold is set to a shape corresponding to the shoe stretch to be processed. The bottom of the upper mold is provided with a groove consistent with the shape of the lower mold surface. The upper mold and the lower mold are pressed together to form the shoe stretcher blank into a corresponding shape.

[0004] The above-mentioned prior art solutions have the following defects: the shoe tree blank is easily displaced when being pressed and shaped between the upper mold and the lower mold, and the stability is not high, so there is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a shoe tree forming mold. Figure 1 A shoe stretcher forming mold includes an upper mold 1 and a lower mold 2. An arc groove 3 is provided at the bottom of the upper mold 1. The top of the lower mold 2 is set to an arc shape. When processing the shoe stretcher blank, the operator places the shoe stretcher blank on the lower mold 2. The upper mold 1 and the lower mold 2 are pressed together to press the shoe stretcher blank into the required shoe stretcher shape. When the upper mold 1 and the lower mold 2 are pressed together, the top of the upper mold 1 abuts against the groove wall of the arc groove 3. The shoe stretcher blank is located between the upper mold 1 and the lower mold 2 and can be fully subjected to pressure, so that it can be deformed quickly. A positioning column 4 is fixed on the lower mold 2. At least one positioning column 4 is provided. The positioning column 4 is vertically fixed to the top of the lower mold 2. A corresponding avoidance groove is provided on the upper mold 1. When the upper mold 1 and the lower mold 2 are pressed together, the positioning column 4 is plugged into the avoidance groove. The positioning column 4 plays a limiting role on the shoe stretcher blank, so that the shoe stretcher blank remains stable during the processing and forming process. The lower mold 2 is a heat-resistant hard rubber block, which plays a buffering role, reduces the impact force on the equipment on which the shoe tree forming mold is installed when the upper mold 1 and the lower mold 2 are pressed together, and plays a protective role.

[0033] Furthermore, a forming groove 5 is provided on the lower mold 2, and a forming block 6 is correspondingly fixed on the upper mold 1. The forming block 6 is adapted to the shape and size of the forming groove 5. When the upper mold 1 and the lower mold 2 are pressed together, the forming block 6 abuts against the groove wall of the forming groove 5. The shoe stretcher blank is located between the upper mold 1 and the lower mold 2 and can be fully subjected to pressure, so that corresponding wrinkle deformation can be pressed out on the shoe stretcher blank. When the shoe stretcher blank is placed inside the shoe, it can better deform with the curvature of the shoe to improve the adaptability of the shoe stretcher blank. Mounting holes 7 are provided on the top of the upper mold 1 and the bottom of the lower mold 2 to facilitate the installation and fixation of the upper mold 1 and the lower mold 2.

[0034] The present application also discloses a shoe tree forming machine. Figure 2 and Figure 3A shoe stretcher forming machine includes a machine body 8 and the above-mentioned shoe stretcher forming mold. The machine body 8 is provided with a lifting assembly 9 and a sliding assembly 10. The upper mold 1 of the shoe stretcher forming mold is installed on the lifting assembly 9. The lifting assembly 9 drives the upper mold 1 of the shoe stretcher forming mold to rise and fall. The lower mold 2 of the shoe stretcher forming mold is installed on the sliding assembly 10. The sliding assembly 10 drives the lower mold 2 of the shoe stretcher forming mold to slide under the upper mold 1. When the operator needs to place the shoe stretcher blank on the lower mold 2, the sliding assembly 10 drives the lower mold 2 to slide to the side close to the operator. The operator aligns the hole on the shoe stretcher blank with the positioning column 4 on the lower mold 2, sets the shoe stretcher blank on the positioning column 4, and places the shoe stretcher blank on the lower mold 2. The sliding assembly 10 then slides the lower mold 2 to the bottom of the upper mold 1, and the lifting assembly 9 drives the upper mold 1 to move toward the lower mold 2 to perform a pressing and molding operation on the shoe stretcher blank.

[0035] Specifically, the lifting assembly 9 includes a lifting cylinder 91 and a hot press plate 92. The lifting cylinder 91 is fixed to the machine body 8 and is arranged vertically, and the piston rod of the lifting cylinder 91 is vertically downward. The hot press plate 92 is horizontally fixed to the piston rod of the lifting cylinder 91, and the upper mold 1 is fixed to the bottom of the hot press plate 92. The sliding assembly 10 includes a sliding cylinder 101 and a slide plate 102. The sliding cylinder 101 is horizontally fixed to the machine body 8, and the slide plate 102 is arranged horizontally. A connecting block 11 is vertically fixed to the end of the slide plate 102 away from the sliding cylinder 101, and the connecting block 11 is fixedly connected to the piston rod of the sliding cylinder 101. The lower mold 2 is fixed to the slide plate 102. The sliding cylinder 101 drives the slide plate 102 to slide horizontally, thereby driving the lower mold 2 to slide horizontally. When the operator needs to place the shoe stretcher blank on the lower mold 2, the slide plate 102 drives the lower mold 2 to slide to the side close to the operator. After placement, the lower mold 2 slides to the bottom of the upper mold 1, and the lifting cylinder 91 drives the hot pressing plate 92 to descend and drives the upper mold 1 to descend, and the shoe stretcher blank on the lower mold 2 is hot pressed.

[0036] Furthermore, a support block 12 is fixed on the machine body 8, and the support block 12 is located below the slide plate 102 and supports the slide plate 102.

[0039] During processing, the upper mold 1 of the shoe stretcher forming mold is installed at the bottom of the hot pressing plate 92, and the lower mold 2 of the shoe stretcher forming mold is installed on the slide plate 102. The sliding cylinder 101 drives the slide plate 102 to slide horizontally, thereby driving the lower mold 2 to slide to the side close to the operator, and the operator places the shoe stretch blank on the lower mold 2. After placement, the lower mold 2 slides to the bottom of the upper mold 1. At this time, the slide plate 102 contacts the contact sensor 13, and the contact sensor 13 sends a sensing signal to the controller 14. The controller 14 controls the lifting cylinder 91 to drive the hot pressing plate 92 to descend and drive the upper mold 1 to descend, and perform hot pressing molding operations on the shoe stretch blank on the lower mold 2. When one group of shoe stretcher forming molds is being processed, the operator can place or take the shoe stretch blanks on the other group of shoe stretcher forming molds, so that the shoe stretcher forming machine can process the two groups of shoe stretch blanks in a continuous manner, thereby improving the processing efficiency.
