Description

Technical Field

[0001] The invention relates to the technical field of shoe processing equipment, in particular to a safety shoe raw material extrusion bonding device. Background Art

[0002] Safety shoes are a special type of footwear that is worn by the wearer on special occasions. Safety shoes can provide good protection for the wearer's feet and prevent the wearer's feet from suffering foreseeable injuries. When actually producing safety shoes, leather is first used to produce the upper, and then a metal sheet with a shape that matches the shape of the sole is padded in the head of the upper. Then, a metal sheet that matches the shape of the sole is cut out and bonded to the upper to form a semi-finished shoe body with a metal sheet sole. Then, a safety shoe bonding device is used to form the sole. The safety shoe bonding device is usually as follows: Figure 1 The bottom mold 1-1 is shown as comprising a bottom mold 1-1, on which a shoe groove 1-2 in the shape of a shoe sole is arranged, and the bottom mold 1-1 is provided with a heating device so that the bottom mold 1-1 can be heated, and the raw material of the safety shoe is placed in the shoe groove 1-2, usually rubber, and then the semi-finished shoe body of the metal sheet sole is placed as a whole on the top of the shoe groove 1-2, so that the bottom of the semi-finished shoe body seals the top of the shoe groove 1-2, and then the bottom mold 1-1 is heated, and the rubber is melted by heat to form a sole shape in the shoe groove 1-2 and directly adhered to the bottom of the semi-finished shoe body, thereby completing the production of the safety shoe, but when using this kind of safety shoe There are certain drawbacks in the production of safety shoes using bonding equipment. During actual bonding, the fit between the bottom of the upper semi-finished shoe body and the top opening of the shoe groove 1-2 is still relatively high. If the local fit is not tight enough, rubber leakage is likely to occur, which increases subsequent processing steps and increases production costs. Moreover, when the rubber in the shoe groove 1-2 is melted and the sole is formed and bonded to the upper semi-finished shoe body, since there is a certain tangential bonding force between the rubber and the side wall of the shoe groove 1-2, when the safety shoe is taken out of the shoe groove 1-2, it is easy to cause scratches on the outer wall of the rubber sole, thereby affecting the appearance.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 2-Figure 13As shown, a safety shoe raw material extrusion and bonding device described in this embodiment is used for the processing and molding production of safety shoes. At that time, rubber is placed on the device, and the rubber is used to be molded into the sole of the safety shoe. Then, the semi-finished shoe body with the metal sheet sole is placed on the device, so that the rubber is at the bottom of the semi-finished shoe body, and then it is extruded, heated, molded and bonded. Specifically, the device includes a bottom mold 1, and the bottom mold 1 is used to heat and melt the rubber. Specifically, during processing, a heating device such as an electric heating wire heats the bottom mold 1, so that the temperature of the bottom mold 1 increases, and then the rubber on the bottom mold 1 is melted and molded. The top of the bottom mold 1 is formed with a sole mold 2, a center mold 3 and a heel mold 4, and the sole mold 2, the center mold 3 and the heel mold 4 are combined to form the sole shape, and the sole mold 2 corresponds to the sole area of ​​the sole, the arch mold 3 corresponds to the arch area of ​​the sole, and the heel mold 4 corresponds to the heel area of ​​the sole. Further, the arch mold 3 is located between the sole mold 2 and the heel mold 4, and one end of the arch mold 3 is connected to the sole mold 2, and the other end of the arch mold 3 is connected to the heel mold 4. More specifically, the sole mold 2, the arch mold 3 and the heel mold 4 are all open platform structures, that is, the top of the sole mold 2 is flat as a whole, the top of the arch mold 3 is flat as a whole, and the top of the heel mold 4 is flat as a whole. More specifically, it also includes a first upper half mold 5 and a second upper half mold 6, and the first upper half mold 5 and the second upper half mold 6 are arranged relatively. At that time, the first upper half mold 5 and the second upper half mold 6 can be separated The first upper mold 5 and the second upper mold 6 are driven by a driving device such as a hydraulic cylinder, and a connecting portion 7 that is convenient for connecting to a driving device such as a hydraulic cylinder is provided on the first upper mold 5 and the second upper mold 6, so that the first upper mold 5 and the second upper mold 6 can approach each other or move away from each other. Specifically, the first upper mold 5 and the second upper mold 6 both move in the horizontal direction, so that the first upper mold 5 and the second upper mold 6 can approach each other and then enclose the bottom mold 1 on the outside of the bottom mold 1, or move away from each other to release the bottom mold 1. In the embodiment of the present application, under the drive of a driving device such as a hydraulic cylinder, when the first upper mold 5 and the second upper mold 6 are enclosed around the periphery of the bottom mold 1, the inner side enclosed cavity shape of the first upper mold 5 and the second upper mold 6 is adapted to the outer shape of the bottom mold 1, that is, the sole shape, after being enclosed, the first upper mold 5, the second upper mold 6 and the bottom mold 1 form a cavity, the bottom wall of the cavity is the top of the bottom mold 1, the side walls of the cavity are the inner wall of the first upper mold 5 and the inner wall of the second upper mold 6, and the bottom wall of the cavity is arranged in a vertical direction, and the cavity is used to place the raw rubber of the safety shoe sole and the semi-finished shoe body. When operating, the rubber is first cut into slices and evenly placed on the top of the bottom mold 1, and then the semi-finished shoe body is placed upright on the rubber, and then the first upper mold 5 and the second upper mold 6 are driven to approach each other until the first upper mold 5 and the second upper mold 6 are enclosed around the periphery of the bottom mold 1. At this time, the first upper mold 5 and the second upper mold 6 can squeeze the bottom periphery of the semi-finished shoe body to a certain extent, and then the bottom mold 1 is heated,The rubber on the top of the bottom mold 1 begins to melt and form, and finally forms the sole and directly adheres to the bottom of the semi-finished shoe body, thereby completing the processing and forming of the safety shoe, and then drives the first upper mold 5 and the second upper mold 6 away from each other, so that the safety shoe is released. At this time, only the bottom of the sole of the safety shoe is in contact with the top of the bottom mold 1. In addition, the residual temperature of the sole and the bottom mold 1 can easily remove the safety shoe from the bottom mold 1. On the one hand, it can effectively avoid damage to the appearance of the safety shoe. On the other hand, under the enclosure of the first upper mold 5 and the second upper mold 6, it can effectively avoid leakage of rubber, which greatly increases the convenience of production and processing, and improves the molding quality.

[0031] Specifically, for the top of the bottom mold 1, the arch mold 3 is located between the sole mold 2 and the heel mold 4, and the top of the arch mold 3 is higher than the top of the sole mold 2 and the top of the heel mold 4, respectively. More specifically, the front end of the sole mold 2 is slightly tilted, so that the molded sole is more adapted to the shape of the human foot and improves the comfort of the wearer. More specifically, a first inclined surface 8 is provided between the arch mold 3 and the sole mold 2, and a second inclined surface 9 is provided between the arch mold 3 and the heel mold 4, and the top of the first inclined surface 8 and the top of the second inclined surface 9 are both facing the arch mold 3. The inclination makes the transition structures between the arch mold 3 and the first inclined surface 8, between the first inclined surface 8 and the sole mold 2, between the arch mold 3 and the second inclined surface 9, and between the second inclined surface 9 and the heel mold 4 all obtuse-angle transition structures. The molten rubber can be more smoothly filled into the corners during molding, thereby improving the molding quality of the safety shoes. More specifically, rounded corner structures are arranged between the arch mold 3 and the first inclined surface 8, between the first inclined surface 8 and the sole mold 2, between the arch mold 3 and the second inclined surface 9, and between the second inclined surface 9 and the heel mold 4, which is more conducive to material molding.

[0032] More specifically, after the first upper mold 5 and the second upper mold 6 are enclosed, a forming mold rod for forming a shock-absorbing groove on the sole is formed between the first upper mold 5 and the second upper mold 6. At that time, after the safety shoes are processed, under the action of the access component, the shock-absorbing groove penetrates the sole of the safety shoes in the left and right directions. On the one hand, it can increase the softness of the sole of the safety shoes and improve comfort. On the other hand, when the wearer walks, it can have a certain buffering and shock-absorbing effect on the feet, reducing damage to the leg joints and foot joints.

[0033] In the embodiment of the present application, the molding mold rod includes a first rod 11 and a second rod 12, and the length directions of the first rod 11 and the second rod 12 are the same. At that time, the movement directions of the first upper mold 5 and the second upper mold 6 are also the same. The length directions of the first rod 11 and the second rod 12 are the same as the above-mentioned movement directions, which facilitates the withdrawal of the first rod 11 and the second rod 12 after the sole is formed. Specifically, the first rod 11 is arranged on one of the first upper mold 5 and the second upper mold 6, and the second rod 12 is arranged on the other of the first upper mold 5 and the second upper mold 6. When the first upper mold 5 and the second upper mold 6 are surrounded, the first rod 11 and the second rod 12 are abutted. Specifically, the end of the first rod 11 and the end of the second rod 12 can be abutted, or the side of the first rod 11 and the side of the second rod 12 can be abutted. In the embodiment of the present application, it is preferred to take the side abutment of the first rod 11 and the second rod 12 as an example. It is explained that, at that time, after the first upper mold 5 and the second upper mold 6 are enclosed on the outside of the bottom mold 1, the first rod 11 and the second rod 12 are parallel and in a side-by-side posture, and the side of the first rod 11 and the side of the second rod 12 abut against each other, thereby forming a molding mold rod between the first upper mold 5 and the second upper mold 6. The molding mold rod occupies a certain space, thereby forming a shock-absorbing groove on the molded rubber sole. More specifically, an isolation area 13 is formed between the first rod 11 and the second rod 12. Specifically, the isolation area 13 is a vacant structure for filling with molten rubber, and then after the sole is formed, a support body can be formed in the shock-absorbing groove. Specifically, the isolation area 13 extends in the vertical direction, so that the support body formed in the shock-absorbing groove is in a vertical direction, and then the support body can further increase the local buffering and shock-absorbing effect, improve the comfort, and can increase the local structural strength of the shock-absorbing groove to a certain extent.

[0034] More specifically, one end of the first rod 11 connected to the first upper mold 5 / the second upper mold 6 is the base, and the other end of the first rod 11 is the end. Similarly, one end of the second rod 12 connected to the second upper mold 6 / the first upper mold 5 is the base, and the other end of the second rod 12 is the end. The base of the first rod 11 is provided with a first enlarged end 15, and the base of the second rod 12 is provided with a second enlarged end 16. Specifically, when the first rod 11 and the second rod 12 are abutted side by side, the position of the first enlarged end 15 on the first rod 11 corresponds to the position of the second rod 12, and the second rod 1 2 corresponds to the position of the first rod 11, so that when the first rod 11 and the second rod 12 are demolded and withdrawn, the support body can avoid interference with the first rod 11 or the second rod 12, and the withdrawal is more convenient. After the first upper half mold 5 and the second upper half mold 6 are enclosed, the first rod 11 and the second rod 12 are in contact side by side, and a gap is provided between the first enlarged end 15 of the first rod 11 and the end of the second rod 12 to form an isolation area 13, and a gap is provided between the second enlarged end 16 of the second rod 12 and the end of the first rod 11 to form an isolation area 13.

[0035] More specifically, with regard to the number and positions of the forming mold rods, at least one forming mold rod is arranged at the position of the sole mold 2, and at least one forming mold rod is arranged at the position of the heel mold 4. That is, at that time, the shock absorbing groove is formed in the sole area and the heel area of ​​the sole. The sole area and the heel area are subjected to large forces, and the human body's heel and sole feel it more obviously, thereby being able to more significantly improve the comfort and more effectively improve the shock absorbing and buffering effect of the sole.

[0036] It should be noted that the lengths of the first rod 11 and the second rod 12 at different positions are adjusted according to actual conditions.

[0037] It is also necessary to explain that when a person walks, the sole of the foot tends to tilt outward, and then when walking, the outer side of the heel of the foot tends to touch the ground first, and then the ground where the foot touches extends toward the sole of the foot, and then the force sequence of the foot is roughly: extending from the outer side of the heel to the inclined direction of the inner side of the sole of the foot. Based on this, when the bottom mold 1 is in the shape of a right foot, the first upper mold 5 is located at the inner side of the foot, and the first rod 11 is arranged on the first upper mold 5. At this time, in the front-back direction of the foot, the first rod 11 is located at the second rod 1 2, and thus the isolation area 13 at the outside of the foot of the sole mold 2 is further away from the center mold 3, and the isolation area 13 at the outside of the foot of the heel mold 4 is closer to the center mold 3. Therefore, the connection line of the two isolation areas 13 on the heel mold 4 can be more perpendicular to the line of the force sequence when the foot touches the ground, and the connection line of the two isolation areas 13 on the sole mold 2 can be more perpendicular to the line of the force sequence when the foot touches the ground. When the foot touches the ground, the force on the foot is more gentle, thereby further improving the comfort.

[0038] More specifically, the end of the first rod 11, the end of the second rod 12, the first enlarged end 15 and the second enlarged end 16 are all provided with an inner arch structure to make the isolation area 13 arc-shaped, thereby making the support body more cylindrical after the sole is formed, making it easier to shape the material and easier to demold the first rod 11 and the second rod 12 after the sole is formed.

[0039] In the embodiment of the present application, the first rod 11 and the second rod 12 are both provided with a first heating cavity 17 for convenient placement of a heating device. As for the form of the first heating cavity 17, it is preferred that the first rod 11 and the second rod 12 are both hollow in shape, thereby forming a hollow first heating cavity 17. An insertion groove 18 for communicating with the first heating cavity 17 is provided on the first upper half mold 5 and the second upper half mold 6. Therefore, a heating device such as a heating wire can be inserted into the first heating cavity 17 through the insertion groove 18 and the first heating cavity 17, so that the first rod 11 and the second rod 12 can generate heat. On the one hand, it is convenient to heat the thicker rubber of the sole mold 2 and the heel mold 4, which is more conducive to the melting and molding of the rubber. On the other hand, after the processing and molding are completed, the first rod 11 and the second rod 12 can maintain a considerable residual heat, which is convenient for the demolding and extraction of the first rod 11 and the second rod 12.

[0040] More specifically, a second heating chamber 19 is provided on the bottom mold 1 for accommodating a heating device. The second heating chamber 19 is provided at the bottom of the bottom mold 1, so as to heat the bottom mold 1 conveniently by means of a heating device such as an electric heating wire, so as to melt the rubber on the top of the bottom mold 1. More specifically, the bottom mold 1, the first upper half mold 5, the second upper half mold 6, the first rod 11 and the second rod 12 are made of metal.
