Description

Technical Field

[0001] The present invention relates to the technical field of shoe processing moulds, and more particularly to a shoe processing mould and a use method thereof. Background Art

[0002] Shoe processing molds refer to various molds used in the footwear manufacturing process to process raw materials into various parts of shoes. These molds play a vital role in footwear manufacturing. The main types include injection molds, die-casting molds, and stamping molds. It is one of the most common parts in shoe processing and is mainly used to make soles. The sole mold is generally composed of a sole template and a sole groove. The sole template is made according to the size and shape of the shoe to ensure the perfect appearance of the sole; the sole groove increases the grip of the sole and prevents slipping. It is mainly used for the processing of soles of sports shoes, beach shoes, slippers, safety shoes and other footwear.

[0003] When processing the soles of safety shoes, the existing shoe processing mold usually places a steel sheet inside the sole during processing. The steel sheet can effectively prevent sharp objects such as nails and gravel from penetrating the sole and protect the foot from injury. First, injection molding is performed in the mold, and then the steel sheet is placed in the mold, and then injection molding is performed in the mold again, so that the injection molding material wraps the steel sheet to complete the processing of the sole. However, when processing the sole, not only two injection moldings are required, but also the steel sheet needs to be manually placed in the mold during the injection molding process, which greatly increases the processing time of the sole and reduces the processing efficiency of the shoe processing mold for the safety shoe sole.

[0016] A shoe processing mold and a method for using the same, comprising the following steps:

[0017] S1: First, place the steel sheet into the groove, then start the positioning assembly, clamp the steel sheet from the outside of the four sides of the steel sheet through six positioning blocks, and place the steel sheet in the groove in mid-air through the placement table;

[0018] S2: Based on step S1, the telescopic rod is started, and then the upper mold is driven to move downward through the mounting plate, so that the protrusion is inserted into the groove, and then the protrusion is pushed into the fourth slide groove through the contact between the outer side of the protrusion and the inclined surface of the positioning block, thereby releasing the positioning of the steel sheet, and at the same time, the steel sheet is fixed to the lower surface of the first slide rod through a magnet so that it remains suspended in the groove, and then the injection molding device is connected to the second injection port, and the molten injection material is injected into the groove;

[0019] S3: When the molten injection material fills the groove, the rotating rod is manually rotated, and then the No. 1 threaded rod is driven to rotate through the meshing connection between the No. 1 worm and the No. 1 worm wheel, thereby driving the connecting plate to move upward, and then the No. 3 slide plate is driven to move upward through the No. 1 straight rod, thereby starting the separation assembly to drive the magnet to move upward, so that the magnet is away from the steel sheet and releases the fixation of the steel sheet;

[0020] S4: After the No. 3 slide plate moves to the upper end of the No. 3 slide slot, the rotating rod is continuously rotated to start the fixing assembly to drive the No. 2 slide plate to move upward, and at the same time drive the No. 1 slide bar to move upward, so that the lower surface of the No. 1 slide bar and the lower surface of the fixing block are in the same plane, and then the limiting assembly is started to drive the No. 1 slide plate and the fixing block to move upward, so that the lower surface of the No. 1 slide bar, the lower surface of the fixing block and the lower surface of the protrusion are in the same plane;

[0021] S5: Based on step S4, the injection molding device is connected to the No. 1 injection port, and the molten injection molding material is injected into the injection pipe. At the same time, the No. 2 straight rod is pushed to move toward the No. 2 slide hole, thereby starting the anti-backflow component to drive the No. 3 slide rod to move upward, so that the outlet end of the injection pipe is opened, thereby injecting the injection molding material into the groove, and into the cavity generated by the upward movement of the fixed block and the No. 1 slide rod, thereby completing the injection molding process of the sole.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This scheme sets a fixing component to place the steel sheet into the groove, and then drives the upper mold to move toward the lower mold so that the protrusion is inserted into the groove, and then fixes the steel sheet through the magnet in the No. 1 slide bar so that the steel sheet is located at the center of the groove, and then injects the molten injection molding material into the groove through the No. 2 injection port to wrap the steel sheet inside the sole, and then rotates the rotating rod to drive the No. 1 worm gear to rotate, thereby driving the No. 1 slide bar to move upward, and then injects the molten injection molding material into the groove through the No. 1 injection port, so that the molten injection molding material fills the cavity inside the groove formed by the upward movement of the No. 1 slide bar, so that the molten injection molding material completely wraps the steel sheet, thereby completing the injection molding process of the safety shoe sole, and there is no need to place the steel sheet in the mold during the injection molding process, which greatly reduces the processing time of the sole and improves the processing efficiency of the shoe processing mold for the safety shoe sole.

[0024] (2) This solution sets a separation component. When the connecting plate drives the No. 1 straight rod to move upward, it first drives the No. 3 sliding plate to move upward, and at the same time drives the No. 2 sliding rod to move upward, thereby driving the magnet to move upward, so that the magnet is away from the steel sheet, thereby eliminating the magnetic attraction effect of the magnet on the steel sheet, and then releasing the fixation of the steel sheet, which can prevent the No. 1 sliding rod from driving the steel sheet upward when moving upward, thereby improving the use effect of the fixing component and thereby improving the quality of the produced soles.

[0025] (3) This solution provides a positioning component, and clamps and fixes the steel sheet through six No. 1 sliders, so that the steel sheet is fixed in the middle position of the groove, thereby improving the use effect of the fixing component, preventing the steel sheet from being exposed in the produced soles, and improving the quality of the soles. The placement table can prevent the steel sheet from sliding downward in the six No. 1 sliders, and at the same time, the steel sheet can be kept flush with the lower end of the inner wall of the groove, thereby facilitating the magnet to fix the steel sheet.

[0052] When the existing shoe processing mold is used, two injection moldings are required, and the steel sheet 10 needs to be placed in the mold during the injection molding process, which greatly increases the processing time of the sole and reduces the processing efficiency of the shoe processing mold for the safety shoe sole.

[0053] like Figure 4 , Figure 5 As shown, a separation component 6 is arranged inside the No. 2 slide 54, and the separation component 6 includes a No. 3 slide groove 61 opened inside the No. 2 slide 54, and the No. 3 slide groove 61 is slidably connected to the inside of the No. 3 slide groove 61.

[0054] like Figure 3 , Figure 4 , Figure 5 As shown, a limiting assembly 7 is arranged between the No. 2 slide 54 and the No. 1 slide 52, and the limiting assembly 7 includes an annular groove 73 opened on the upper surface of the No. 1 slide 52, and an annular slider 74 is fixedly connected to the lower surface of the No. 2 slide 54, and the annular slider 74 is slidably connected to the annular groove 73, and a limiting groove 71 is opened at the lower end of the outer surface of the No. 2 slide 54, and a limiting ring 72 is fixedly connected to one side of the inner wall of the No. 1 groove 51, and the limiting ring 72 is located above the No. 1 slide 52, and the limiting ring 72 is slidably connected to the limiting groove 71.

[0055] In the above embodiment, the steel sheet 10 is fixed by the magnet 514 in the No. 1 slide bar 55, so that the steel sheet 10 is located at the center position in the groove 3, and then the groove 3 is injected once through the No. 2 injection port 16, and then the fixing component 5 is started to drive the No. 1 slide bar 55 to move upward, so that the No. 1 slide bar 55 is separated from the steel sheet 10, and then the groove 3 is injected once through the No. 1 injection port 515 to fill the cavity formed by the upward movement of the No. 1 slide bar 55, so that the injection material completely wraps the steel sheet 10. However, because the steel sheet 10 is fixed to the lower surface of the No. 1 slide bar 55 by adsorption by the magnet 514, the No. 1 slide bar 55 can easily drive the steel sheet 10 when moving upward, thereby causing the steel sheet 10 to be misplaced, affecting the use effect of the fixing component 5 and reducing the quality of the produced sole. Therefore, a separation component 6 is provided. When the connecting plate 58 drives the No. 1 straight rod 56 to move upward, it first drives the No. 3 slide plate 62 to move upward in the No. 3 slide groove 61, and at the same time drives the No. 2 slide bar 64 to move upward, thereby driving the magnet 514 to move upward in the No. 1 slide hole 63, so that the magnet 514 is away from the steel sheet 10, thereby eliminating the magnetic attraction effect of the magnet 514 on the steel sheet 10, and then releasing the fixation of the steel sheet 10, which can prevent the No. 1 slide bar 55 from driving the steel sheet 10 to move upward when moving upward, thereby improving the use effect of the fixing component 5, and thereby improving the quality of the produced soles, and then continuing to move the No. 1 straight rod 56 upward, so that the No. 3 slide plate 62 moves to the upper end inside the No. 3 slide groove 61, thereby driving the No. 2 slide plate 54 to move upward, and at the same time driving the No. 1 slide bar 55 to move upward, so that the No. 1 slide bar 55 is separated from the steel sheet 10.

[0056] In the above embodiment, when the No. 3 slide plate 62 moves upward, the separation component 6 first drives the magnet 514 to move upward away from the steel sheet 10, eliminating the magnetic attraction effect of the magnet 514 on the steel sheet 10, thereby releasing the fixation of the steel sheet 10, and then drives the No. 1 slide bar 55 to move upward, so that the No. 1 slide bar 55 is separated from the steel sheet 10, and then the molten injection molding material is injected into the groove 3 through the No. 1 injection port 515 and the injection pipe 516, and at the same time, the No. 1 slide plate 52 and the fixed block 53 are pushed upward, so that the molten injection molding material can be better filled into the cavity formed by the several No. 1 slide bars 55 and the fixed block 53, so that the steel sheet 10 is completely wrapped. However, the molten injection molding material is injected into the groove 3, pushing the fixed block 53 to move upward, so that the lower surface of the fixed block 53 and the No. 1 slide bar 55 are in different planes, so that the upper surface of the produced sole is uneven, which reduces the quality of the produced sole. Therefore, the limiting assembly 7 is provided, and when the No. 2 slide plate 54 drives the No. 1 slide bar 55 to move upward, the annular slide block 74 is also driven to move upward in the annular slide groove 73. When the No. 1 slide bar 55 moves upward, the lower surface of the No. 1 slide bar 55 and the lower surface of the fixing block 53 are located in the same plane, the No. 1 slide plate 52 is driven to move upward, thereby driving the fixing block 53 to move upward, so that the fixing block 53 and the No. 1 slide bar 55 move upward at the same time. When the No. 2 slide plate 54 moves upward to the top end in the No. 1 slide groove 51, the lower surface of the No. 1 slide bar 55, the lower surface of the fixing block 53 and the lower surface of the protrusion 4 are in the same plane. At the same time, the setting of the limiting ring 72 and the limiting groove 71 can prevent the No. 1 slide plate 52 from moving upward, and it can be ensured that the lower surface of the No. 1 slide bar 55, the lower surface of the fixing block 53 and the lower surface of the protrusion 4 are in the same plane, so that the upper surface of the produced sole remains flat, thereby improving the quality of the produced sole.

[0057] like Figure 1 , Figure 6 , Figure 7 As shown, a positioning component 8 is arranged inside the groove 3, and the positioning component 8 includes six No. 4 slide grooves 81 which are evenly distributed in an annular shape and opened on one side of the inner wall of the groove 3, and the six No. 4 slide grooves 81 are slidably connected with positioning blocks 82, and the six No. 5 slide grooves 83 are arranged on the inner wall of the six No. 4 slide grooves 81 away from the positioning blocks 82, and the six No. 5 slide grooves 83 are slidably connected with No. 1 sliders 84, one side of the outer surface of the six No. 1 sliders 84 is fixedly connected with No. 1 connecting rods 85, and the other ends of the No. 1 connecting rods 85 are fixedly connected to the positioning blocks 82, and No. 1 springs 86 are arranged on the other side of the outer surfaces of the six No. 1 sliders 84, and a placement table 87 is arranged on the outer surface of the positioning block 82 away from the No. 1 connecting rod 85.

[0058] In the above embodiment, the steel sheet 10 is placed in the groove 3, the upper mold 2 is moved to the lower mold 1, the protrusion 4 is inserted into the groove 3, and the steel sheet 10 is fixed to the lower surface of the No. 1 slide bar 55 by the magnet 514. However, when the steel sheet 10 is placed in the groove 3, it cannot be ensured that the steel sheet 10 is located in the middle position of the groove 3, so that the steel sheet 10 will stick to the inner wall of the groove 3, so that when the magnet 514 fixes the steel sheet 10 on the lower surface of the No. 1 slide bar 55, it cannot be ensured that the steel sheet 10 is located in the center position of the groove 3, which reduces the use effect of the fixing component 5, and the steel sheet 10 sticks to the inner wall of the groove 3, which easily causes the steel sheet 10 in the produced sole to be exposed, reducing the quality of the sole. Therefore, the positioning component 8, when the steel sheet 10 is added to the groove 3, drives the No. 1 slider 84 to move in the No. 5 slide groove 83 through the No. 1 spring 86, and then drives the positioning block 82 to move in the No. 4 slide groove 81 through the No. 1 connecting rod 85, so as to prevent the steel sheet 10 from being stuck to the inner wall of the groove 3. The six No. 1 sliders 84 are moved toward the steel sheet 10 at the same time, clamping and fixing the steel sheet 10 so that the steel sheet 10 is fixed in the middle position in the groove 3, thereby improving the use effect of the fixing component 5, preventing the steel sheet 10 in the produced sole from being exposed, and improving the quality of the sole. The placement table 87 can prevent the six No. 1 sliders 84 from sliding downward, and at the same time, the steel sheet 10 can be kept flush with the lower end of the inner wall of the groove 3. When the protrusion 4 is inserted into the groove 3, the protrusion 4 first contacts the inclined surface of the No. 1 slider 84, pushing the six No. 1 sliders 84 to move away from the steel sheet 10 at the same time, thereby releasing the clamping and fixing of the steel sheet 10, and then the steel sheet 10 is sucked upward by the magnet 514, so that the steel sheet 10 is fixed on the lower surface of the No. 1 slide bar 55, and then the protrusion 4 is continued to be inserted into the groove 3, pushing the six No. 1 sliders 84 and the placement table 87 to move away from the steel sheet 10, so that the steel sheet 10 can move downward.

[0061] In the above embodiment, after the upper mold 2 and the lower mold 1 are molded together, the first injection molding is performed in the groove 3 through the second injection port 16, and then the fixing assembly 5 is started to drive the first slide bar 55 and the fixing block 53 to move upward, so that the lower surface of the first slide bar 55, the lower surface of the fixing block 53 and the lower surface of the protrusion 4 are on the same plane, and then the second injection molding is performed in the groove 3 through the first injection port 515 and the injection pipe 516. However, during the first injection molding, the molten injection material will enter the injection pipe 516, thereby affecting The second injection molding reduces the injection molding effect of the second injection molding, so the anti-backflow component 9 is set, and the outlet end of the injection pipeline 516 is blocked by the third slide bar 93 set at the outlet end of the injection pipeline 516, thereby preventing the molten injection molding material from entering the injection pipeline 516 during the first injection molding, reducing the impact on the second injection molding, and improving the injection molding effect of the second injection molding.

And the No. 2 spring 915 can drive the rack 911 and the No. 2 straight rod 912 to move in the opposite direction, so that the rack 911 and the No. 2 straight rod 912 can be automatically reset, which is convenient for the reuse of the anti-backflow component 9. At the same time, the No. 3 straight rod 914 is slidably connected with the No. 2 sliding hole 913, which can limit the movement of the rack 911 and the No. 2 straight rod 912 to prevent the No. 2 straight rod 912 from completely entering the No. 7 slide groove 910, so that the molten injection molding material enters the No. 7 slide groove 910, affecting the normal use of the anti-backflow component 9.
