Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shoe processing, in particular to a production mould for popcorn shoe outsoles. Background Art
[0002] The popcorn shoe outsole is formed by countless TPU foam balls gathered together. Like traditional shoe outsole, it is made of molds, easy to process and has a wide range of design space. Although the traditional rubber outsole has good elasticity, it is heavy. The popcorn shoe outsole formed by countless TPU foam balls is not only elastic but also lighter. At the same time, the popcorn shoe outsole is degradable and more environmentally friendly. Therefore, this type of shoe outsole is gradually becoming popular.
[0003] The application number is 202223537662.1, which is a popcorn shoe machine that is convenient for mold forming and unloading, including a bottom plate, the upper surface of the bottom plate is fixedly connected to a shell, the top of the shell is fixedly connected to a cylinder, one end of the cylinder piston rod passes through the shell and is fixedly connected to a T-frame, the bottom of the T-frame is fixedly connected to a shoe-shaped pressing block, one side inner wall of the shell is fixedly connected to a fixed plate, a plurality of placement grooves are provided inside the fixed plate, a mold is movably connected in the placement groove, and two rubber ropes are fixedly connected to the inner wall of one side of the shell, and the rubber rope is fixed to the mold. The utility model can not only enable the device to automatically unload materials through a push plate, thereby improving the unloading effect of the device, but also can guide the wire rope through a roller, thereby improving the guiding effect of the device, and can also conveniently collect the soles through a receiving box, thereby facilitating centralized processing by the staff and improving the convenience of the device.
[0004] This technical solution facilitates the pushing of the molded shoe outsole from the mold by setting a push plate. After long-term use, the gap between the push plate and the mold increases due to wear, causing the mold cavity to become larger, which can easily lead to a larger size of the shoe outsole produced subsequently, or aggravate the generation of flash, making it more difficult to subsequently remove and polish the shoe outsole. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a popcorn shoe outsole production mold to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a popcorn shoe outsole production mold, including a mold body, a cavity is opened inside the mold body, and a piston is connected to the cavity, a counterweight block is connected to the bottom of the piston, and a push rod is connected to the top of the piston, a heat conduction plate is connected to the top of the cavity, and a baffle is connected to the top of the heat conduction plate, and ventilation pipes pass through both sides of the mold body.
[0007] By adopting the above technical solution, when the temperature of the mold body drops, the popcorn shoe outsole is cooled and formed, and at the same time, the baffle made of nickel-titanium memory alloy is deformed due to the temperature drop, so that the inner circle of the baffle is away from the ejector rod, thereby avoiding the wear of the ejector rod and the inner circle of the baffle when the ejector rod is subsequently raised, resulting in an increase in the gap, thereby avoiding the appearance of flash in the area between the two during subsequent processing.
[0008] Furthermore, the baffle is made of nickel-titanium shape memory alloy, and the heat conducting plate is made of copper.
[0009] By adopting the above technical solution, the baffle made of nickel-titanium memory alloy is deformed due to the decrease in temperature, so that the inner circle of the baffle is away from the push rod, avoiding the increase in the gap due to wear between the push rod and the inner circle of the baffle when the push rod is raised, and the high temperature cooperates with the heat conduction plate to transfer heat to restore the baffle to a horizontal state and fit firmly with the outer circle of the push rod.
[0010] Furthermore, the push rod is slidably connected to the heat conducting plate, and the piston is slidably connected to the cavity.
[0011] By adopting the above technical solution, normal temperature air is input into the ventilation pipe through an external air pump. Since the air flow can only enter the ventilation pipe and cannot be discharged, the air pressure in the ventilation pipe and the cavity increases. After the air pressure increases, the piston is affected by the air pressure and drives the push rod to move upward to push out the shoe outsole to complete the unloading.
[0012] Furthermore, the ventilation pipe is serpentine-shaped, and the ventilation pipe is connected to the cavity. The ventilation pipe is serpentine-shaped, and the ventilation pipe is connected to the cavity.
[0013] By adopting the above technical solution, when hot air is input into the ventilation pipe through an external air pump and a heater, the hot air heats up the mold body. When normal temperature air is input into the ventilation pipe through an external air pump, the air flow can only enter the ventilation pipe and cannot be discharged, thereby increasing the air pressure in the ventilation pipe and the cavity. After the air pressure increases, the piston is affected by the air pressure and drives the push rod to move upward.
[0014] Furthermore, the counterweight is made of lead.
[0015] By adopting the above technical solution, the air pressure in the ventilation pipe is greater than the external air pressure, and the counterweight block is affected by gravity, so that the piston and the push rod move downward and reset, and the air flow in the ventilation pipe is discharged.
[0016] Furthermore, the outer ring of the baffle is fixedly connected to the mold body, and the inner ring of the baffle is in contact with the ejector rod.
[0017] By adopting the above technical solution, the high temperature cooperates with the heat conducting plate to transfer heat so that the baffle returns to a horizontal state and fits tightly with the outer ring of the ejector rod. When the temperature drops, the baffle deforms, thereby moving the inner ring of the baffle away from the ejector rod.
[0018] Furthermore, cooling water tanks are provided above both sides of the mold body.
[0019] By adopting the above technical solution, after the industrial chiller is started, low-temperature cooling water flows in the cooling water tank, thereby taking away the heat of the mold body, parts inside the mold body and raw materials. At this time, the heat of the raw materials is taken away and solidification and forming begins.
[0020] Furthermore, a positioning hole is provided on the top of the mold body, a groove is provided on the top of the mold body, and a nail hole and a pipe position column are respectively connected inside the groove.
[0021] By adopting the above technical solution and setting the groove, the softened raw material can be adapted to the shape of the groove after solidification to form a shoe outsole.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model arranges a baffle, a push rod, a ventilation pipe, a piston, a counterweight and a heat conducting plate. When the temperature of the mold body drops, the popcorn shoe outsole is cooled and formed. At the same time, the baffle made of nickel-titanium memory alloy is deformed due to the temperature drop, so that the inner circle of the baffle is away from the push rod, and the wear of the push rod and the inner circle of the baffle is avoided when the push rod is subsequently raised, resulting in an increase in the gap, so as to avoid flash in the area between the two during subsequent processing; when loading, the valves at both ends of the ventilation pipe are opened and hot air is input into the ventilation pipe. The hot air heats up the mold body, and firstly, after the cold mold body contacts the raw material, the mold body absorbs the heat of the raw material, resulting in direct solidification of the raw material that entered first Solid, secondly, the high temperature cooperates with the heat conduction plate to transfer heat to make the baffle restore to a horizontal state and fit firmly with the outer ring of the ejector rod. At the same time, since the airflow at both ends of the ventilation pipe can circulate, the air pressure in the pipe will not be too high, and due to the weight of the counterweight block, the ejector rod is subjected to downward gravity to prevent the ejector rod from rising, and then the raw material can be input into the mold body; when unloading, the valves at both ends of the ventilation pipe are opened and closed to input cold air into the ventilation pipe. Since the airflow can only enter the ventilation pipe and cannot be discharged, the air pressure in the ventilation pipe and the cavity increases. After the air pressure increases, the piston is affected by the air pressure to drive the ejector rod to move up to push out the shoe outsole to complete the unloading; it is convenient for loading and unloading, with less wear and effectively reducing the generation of flash.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0030] The following describes an embodiment of the utility model based on its overall structure.
[0031] Embodiment 1:
[0032] A popcorn shoe outsole production mold, such as Figure 1-Figure 4 As shown, it includes a mold body 1, a cavity 11 is opened inside the mold body 1, a piston 8 is connected inside the cavity 11, the piston 8 is slidably connected to the cavity 11, a counterweight 9 is connected to the bottom of the piston 8, because the counterweight 9 is affected by gravity, the piston 8 and the push rod 6 are moved down to reset the air flow in the ventilation pipe 7 to be discharged; the counterweight 9 is made of lead, the top of the piston 8 is connected to the push rod 6, the push rod 6 is slidably connected to the heat conducting plate 10, after the air pressure increases, the piston 8 is affected by the air pressure to drive the push rod 6 to move up to push out the shoe outsole to complete the blanking; the upper part of the cavity 11 is connected to the heat conducting plate 10, the heat conducting plate 10 is made of copper, and the high temperature cooperates with the heat conducting plate 10 to transfer heat to restore the baffle 5 to the horizontal The state is firmly fitted with the outer circle of the push rod 6; a baffle 5 is connected to the top of the heat conducting plate 10, and the baffle 5 is made of nickel-titanium memory alloy. The outer circle of the baffle 5 is fixedly connected to the mold body 1, and the inner circle of the baffle 5 abuts against the push rod 6. The baffle 5 made of nickel-titanium memory alloy is deformed due to the temperature drop, so that the inner circle of the baffle 5 is away from the push rod 6, so as to avoid the wear of the push rod 6 and the inner circle of the baffle 5 when the push rod 6 is raised, resulting in an increase in the gap, so as to avoid burrs in the area between the two during subsequent processing; ventilation pipes 7 are passed through both sides of the mold body 1, and the ventilation pipes 7 are serpentine, and the ventilation pipes 7 are connected with the cavity 11, so as to facilitate the delivery of hot air to heat the mold body 1 and the delivery of normal temperature air to lift the push rod 6 and the piston 8.
[0033] See also Figure 1 and Figure 2 In the above embodiment, a positioning hole 2 is provided on the top of the mold body 1, and a groove is provided on the top of the mold body 1. The inside of the groove is respectively connected with a hanging nail hole 3 and a pipe position column 4, which is convenient for solidifying the raw materials to form a popcorn shoe outsole.
[0034] Embodiment 2:
[0035] On the basis of the above-mentioned embodiment 1, although the baffle 5, the push rod 6, the ventilation pipe 7, the piston 8, the counterweight block 9 and the heat conduction plate 10 are provided, the loading and unloading can be convenient and the wear is small and the generation of burrs can be effectively reduced; however, the baffle 5 made of the memory alloy has a slow speed of restoring the low-temperature shape and a slow speed of solidifying the raw material; now, by providing a cooling water tank 12, the speed of restoring the low-temperature shape of the baffle 5 and the speed of solidifying the raw material can be accelerated.
[0036] See also Figure 2 In the above embodiment, cooling water troughs 12 are opened above both sides of the mold body 1. Both sides of the cooling water troughs 12 are connected to the external industrial chiller through pipes. After the industrial chiller is started, low-temperature cooling water flows in the cooling water troughs 12, thereby taking away the heat of the mold body 1, the parts inside the mold body 1 and the raw materials. At this time, the heat of the raw materials is taken away and solidification and forming begins.
[0037] The implementation principle of the utility model is as follows: first, one end of the ventilation pipe 7 is connected to the electromagnetic valve for air intake and the air pump for generating air flow, and a heater is connected to the air intake end of the air pump or between the air pump and the electromagnetic valve for air intake, and the other end of the ventilation pipe 7 is connected to the electromagnetic valve for exhaust, and at the same time, both sides of the cooling water tank 12 are connected to the industrial chiller through pipelines to form a circulation;
[0038] When loading, the staff opens the solenoid valves at both ends of the ventilation pipe 7, and inputs hot air into the ventilation pipe 7 through the external air pump and heater. The hot air heats up the mold body 1. First, it prevents the mold body 1 from absorbing the heat of the raw materials after the cold mold body 1 contacts the raw materials, causing the raw materials that enter first to solidify directly. Second, the high temperature cooperates with the heat conducting plate 10 to transfer heat so that the baffle 5 returns to a horizontal state and fits tightly with the outer ring of the ejector rod 6. At the same time, since the airflow at both ends of the ventilation pipe 7 can circulate, the air pressure in the pipe will not be too high, and due to the weight of the counterweight block 9, the ejector rod 6 is subjected to downward gravity, thereby preventing the ejector rod 6 from rising. Then the raw materials can be input into the mold body 1;
[0039] After the loading is completed, the staff turns on the external industrial chiller. After the industrial chiller is started, low-temperature cooling water flows in the cooling water tank 12, thereby taking away the heat of the mold body 1, the parts in the mold body 1 and the raw materials. At this time, the heat of the raw materials is taken away and solidification and forming begins;
[0040] When unloading, the staff opens and closes the electromagnetic valves at both ends of the ventilation pipe 7, wherein the electromagnetic valve for air intake is opened and the electromagnetic valve for air exhaust is closed. Then, the staff inputs normal temperature air into the ventilation pipe 7 through an external air pump. Since the air flow can only enter the ventilation pipe 7 and cannot be discharged, the air pressure in the ventilation pipe 7 and the cavity 11 increases. After the air pressure increases, the piston 8 is affected by the air pressure and drives the push rod 6 to move upward to push out the shoe outsole to complete the unloading. The baffle 5 made of nickel-titanium memory alloy is deformed due to the decrease in temperature, so that the inner circle of the baffle 5 is away from the push rod 6, so as to avoid the wear of the push rod 6 and the inner circle of the baffle 5 when the push rod 6 is raised, resulting in an increase in the gap, so as to avoid flash in the area between the two during subsequent processing;
[0041] After unloading is completed, the staff will turn off the external air pump and open all the solenoid valves at both ends of the ventilation pipe 7. At this time, since the air pressure in the ventilation pipe 7 is greater than the external air pressure, and since the counterweight block 9 is affected by gravity, the piston 8 and the push rod 6 move down and reset, and the air flow in the ventilation pipe 7 is discharged.
[0042] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
