Description

Technical Field

[0001] This utility model relates to the field of shoe sole forming mold technology, and in particular to a breathable steel shoe sole forming mechanism and forming mold. Background Technology

[0002] Breathable steel is a type of stainless steel made from fine-particle spherical powder sintered at high temperature. It has tiny vent holes evenly distributed in all directions inside, and is also called porous material or porous metal. When used in injection molds, it can reduce injection pressure, reduce molding and holding time, and reduce and eliminate internal stress in the molded parts, preventing product deformation and warping. Breathable steel is often used in molds for shoe soles.

[0003] The patent titled "A Shoe Sole Blank Molding Mold" (patent application number: 202222158628.7) discloses a shoe sole blank molding mold, including a lower mold and an upper mold. A vibration component is connected to the lower end of the lower mold, and a second handle is connected to the front end of the lower mold. A third handle is connected to the front end of the upper mold. A limiting post is connected to the upper end of the limiting post, and a knob is installed on the upper end of the limiting post. A connecting cylinder is connected to the lower end of the knob, and a limiting disc is connected to the lower end of the connecting cylinder. An embedding groove is formed at the connection between the connecting cylinder, the limiting disc, and the limiting post. A through hole is formed at the connection between the upper mold and the limiting post and the knob. By setting a base, spring, connecting shaft, bearing, connecting seat, lever, handle, and first handle at the lower end of the shoe sole blank molding mold, the rubber raw material in the lower mold can be evenly distributed, effectively reducing the generation of air bubbles, thereby improving the quality of the shoe sole blank.

[0004] In the above case, during use, the staff needs to manually rotate the handle to make the lower mold vibrate, which can make the rubber material in the lower mold evenly distributed and effectively reduce the generation of air bubbles. However, manual operation is time-consuming and labor-intensive, especially when the soles need to be mass-produced, which will make the staff very tired and reduce the production efficiency of the soles.

[0005] Therefore, it is necessary to propose a breathable steel sole forming mechanism and forming mold to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a breathable steel shoe sole forming mechanism and forming mold to solve the problem mentioned in the background art that manual operation is time-consuming and labor-intensive, especially when shoe soles need to be mass-produced, which will cause workers to be very tired and reduce the production efficiency of shoe soles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a breathable steel shoe sole forming mechanism, comprising a base, a lower mold and an upper mold, wherein a vibration component is provided on the top of the base; The vibration assembly includes a support column, a telescopic rod, a spring, and a vibration motor; The support column has a placement groove inside, which is slidably connected to the outside of the telescopic rod. One end of the telescopic rod that extends into the placement groove is fixedly connected to the top of the spring, and the other end of the telescopic rod is fixedly connected to the bottom of the lower mold. The bottom of the lower mold is fixedly connected to the top of the vibration motor.

[0008] Preferably, the end of the spring away from the telescopic rod is fixedly connected to the bottom of the placement groove.

[0009] Preferably, the lower mold has a pouring cavity inside, and a demolding assembly is provided inside the pouring cavity. The demolding assembly includes a top plate and a transmission rod. The outside of the top plate is slidably connected to the inner wall of the pouring cavity, and the top of the top plate is fixedly connected to the top of the transmission rod. The outside of the transmission rod is slidably connected to the inside of the lower mold, and the length of the transmission rod is less than the length of the support column.

[0010] Preferably, the base has a sliding groove inside, a support block is slidably connected inside the sliding groove, and an avoidance groove is inside the support block, the avoidance groove being located directly below the vibration motor.

[0011] Preferably, the lower mold is hinged to the outside of the upper mold, and the lower mold is threaded with a screw, while the upper mold has a connecting groove inside.

[0012] This application also proposes a molding die, including the above-mentioned breathable steel sole molding mechanism.

[0013] The technical effects and advantages of this utility model are as follows: 1. By setting up a vibration component, after the rubber raw material for the shoe sole is poured into the lower mold, the vibration motor can be turned on. At this time, the support block is not at the bottom of the lower mold, and the vibration motor will drive the lower mold to vibrate. Since the lower mold is limited by the support column and telescopic rod, the lower mold will only vibrate up and down, which can make the rubber raw material in the lower mold evenly distributed, effectively reduce the generation of air bubbles, and thus improve the molding quality of the shoe sole; and can automatically vibrate the lower mold, avoiding the time-consuming and labor-intensive problem of manual operation, thereby improving the production efficiency of the shoe sole. 2. After the rubber raw material has cooled, the upper mold can be lifted, and then the support block can be slid to the bottom of the lower mold through the slide. The vibration motor can be turned on again, and the vibration motor will drive the lower mold to move up and down. When the lower mold drives the transmission rod to move downward, the transmission rod will be blocked by the support block, causing the transmission rod to drive the top plate to move upward. The top plate will drive the cooled shoe sole to move upward, thereby pushing the shoe sole out of the casting cavity, which facilitates the quick demolding of the shoe sole and brings convenience to the use of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1 - Figure 4The present invention provides a technical solution, the main body of which includes a base 1, a lower mold 5 and an upper mold 15. A vibration assembly is provided on the top of the base 1. The vibration assembly includes a support column 2, a telescopic rod 3, a spring 4 and a vibration motor 6. A placement groove is provided inside the support column 2. The inside of the placement groove is slidably connected to the outside of the telescopic rod 3. One end of the telescopic rod 3 that extends movably into the placement groove is fixedly connected to the top of the spring 4, and the other end of the telescopic rod 3 is fixedly connected to the bottom of the lower mold 5. The bottom of the lower mold 5 is fixedly connected to the top of the vibration motor 6, and the end of the spring 4 away from the telescopic rod 3 is fixedly connected to the bottom of the placement groove. After the rubber material for the shoe sole is poured into the lower mold 5, the vibration motor 6 can be turned on. The vibration motor 6 will drive the lower mold 5 to vibrate. Since the lower mold 5 is limited by the support column 2 and the telescopic rod 3, the lower mold 5 will only vibrate up and down, which can make the rubber material in the lower mold 5 evenly distributed, effectively reduce the generation of air bubbles, and thus improve the molding quality of the shoe sole. It can also automatically vibrate the lower mold 5, avoiding the time-consuming and laborious problem of manual operation, thereby improving the production efficiency of the shoe sole.

[0021] In addition, the lower mold 5 has a pouring cavity 7 inside, and a demolding assembly is provided inside the pouring cavity 7. The demolding assembly includes a top plate 8 and a transmission rod 9. The outside of the top plate 8 is slidably connected to the inner wall of the pouring cavity 7, and the top of the top plate 8 is fixedly connected to the top of the transmission rod 9. The outside of the transmission rod 9 is slidably connected to the inside of the lower mold 5. The length of the transmission rod 9 is less than the length of the support column 2. The base 1 has a sliding groove 10 inside, and a support block 11 is slidably connected inside the sliding groove 10. The support block 11 has an clearance groove 12 inside, and the clearance groove 12 is located directly below the vibration motor 6. After the rubber material has cooled, the upper mold 15 can be lifted, and the support block 11 can be slid to the bottom of the lower mold 5 through the slide groove 10. The vibration motor 6 can be turned on again, and the vibration motor 6 will drive the lower mold 5 to move up and down reciprocally. When the lower mold 5 drives the transmission rod 9 to move downward, the transmission rod 9 will be blocked by the support block 11, causing the transmission rod 9 to drive the top plate 8 to move upward. The top plate 8 will drive the cooled shoe sole to move upward, thereby pushing the shoe sole out of the casting cavity 7, which facilitates the quick demolding of the shoe sole and brings convenience to the use of the device. The clearance groove 12 can prevent the vibration motor 6 from contacting the support block 11 and causing damage to the vibration motor 6. Since the length of the transmission rod 9 is less than the length of the support column 2, it avoids the problem of the transmission rod 9 contacting the base 1 when the rubber material inside the casting cavity 7 is first vibrated, which would affect the molding of the rubber material.

[0022] Finally, the lower mold 5 is hinged to the upper mold 15, and the lower mold 5 is threaded with a screw 14 inside. The upper mold 15 has a connecting groove 13 inside. When it is necessary to close the lower mold 5 and the upper mold 15, the upper mold 15 can be pulled down so that the vertical screw 14 passes through the connecting groove 13, and then the screw 14 can be rotated so that the screw 14 becomes horizontal and locks the upper mold 15.

[0023] Working principle: After the rubber raw material for the shoe sole is poured into the lower mold 5, the vibration motor 6 can be turned on. At this time, the support block 11 is not at the bottom of the lower mold 5. The vibration motor 6 will drive the lower mold 5 to vibrate. Since the lower mold 5 is limited by the support column 2 and the telescopic rod 3, the lower mold 5 will only vibrate up and down, which can make the rubber raw material in the lower mold 5 evenly distributed, effectively reducing the generation of air bubbles, thereby improving the molding quality of the shoe sole. It can also automatically vibrate the lower mold 5, avoiding the time-consuming and laborious problem of manual operation, thereby improving the production efficiency of the shoe sole. After the rubber raw material has cooled, the upper mold 15 can be lifted, and then the support block 11 can be slid to the bottom of the lower mold 5 through the slide groove 10, and the vibration motor can be turned on again. The motor 6, or vibration motor 6, drives the lower mold 5 to move up and down reciprocally. When the lower mold 5 drives the transmission rod 9 to move downward, the transmission rod 9, due to the obstruction of the support block 11, causes the transmission rod 9 to drive the top plate 8 to move upward. The top plate 8 then drives the cooled shoe sole upward, thereby pushing the shoe sole out of the casting cavity 7, facilitating the quick demolding of the shoe sole and bringing convenience to the use of the device. The clearance groove 12 can prevent the vibration motor 6 from contacting the support block 11, thus preventing damage to the vibration motor 6. Since the length of the transmission rod 9 is less than the length of the support column 2, it avoids the problem of the transmission rod 9 contacting the base 1 when the rubber material inside the casting cavity 7 is initially vibrated, which would affect the molding of the rubber material.
