DETAILED DESCRIPTION
[0018] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figure 1-Figure 4 As shown, the utility model provides a blister tray mold, including a base 1, a mold protrusion 2 is fixedly connected to the upper surface of the base 1, and the mold protrusion 2 is set in plurality. When used specifically, a vacuum pump and other structures are also provided for cooperation. The blister molding is an existing common technology and will not be described in detail here.
[0020] Considering that the tray material needs to be heated during the processing, and then needs to be cooled naturally or by external blowing after vacuum adsorption molding, it is difficult to quickly dissipate the heat on the side of the tray wrapped on the base 1 and the mold bump 2. In order to improve the heat dissipation efficiency, a first gas channel 6 is opened inside the base 1 and the mold bump 2. The first gas channel 6 is an inverted U-shaped structure inside the mold bump 2. When the low-temperature gas flows inside the first gas channel 6, it will take away the heat from the side of the tray wrapped on the base 1 and the mold bump 2.
[0021] In order to improve the demoulding efficiency, a square groove 5 is provided on the top of the mold convex block 2, a slider 4 is slidably connected inside the square groove 5, a top plate 3 is fixedly connected to the top of the slider 4, a second gas channel 7 is provided inside the mold convex block 2, the square groove 5 is connected to the first gas channel 6 through the second gas channel 7, and a first solenoid valve 8 is fixedly installed inside the second gas channel 7. When the first solenoid valve 8 is opened, the square groove 5 is connected to the first gas channel 6 through the second gas channel 7, and gas enters the inside of the square groove 5, so that the slider 4 drives the top plate 3 to move upward, lifts the tray, and improves the demoulding efficiency.
[0022] A first air cavity 10 is provided at one end of the base 1, and a cooling device 12 is fixedly installed inside the first air cavity 10. The cooling device 12 includes a cooling plate and other structures, and can quickly cool the gas passing through the first air cavity 10. A second air cavity 11 is provided at the other end of the base 1, and one end of the first gas channel 6 is connected to the first air cavity 10, and the other end of the first gas channel 6 is connected to the second air cavity 11.
[0023] An air pipe 9 for suction and air supply is fixedly connected to the outer wall of the base 1, and the air pipe 9 is connected to the second air cavity 11. When in use, a pump body is provided to connect with the air pipe 9 (not shown in the figure), and the pump body can switch between suction and air supply. The pump body is a common existing technology and will not be described in detail here.
[0024] An air groove 13 is formed at one end of the base 1 close to the first air cavity 10 . The air groove 13 is communicated with the first air cavity 10 . A second solenoid valve 14 is fixedly installed inside the first air cavity 10 .
[0025] After vacuum adsorption molding, the second solenoid valve 14 is opened, the first solenoid valve 8 is closed, and the pump body suction operation is controlled. The pump body sucks the external air through the second air cavity 11, the first gas channel 6, the first air cavity 10 and the gas groove 13. The cooling device 12 can quickly cool the gas passing through the first air cavity 10. When the low-temperature gas flows inside the first gas channel 6, it will take away the heat of the tray wrapped on the base 1 and the mold bump 2, thereby improving the heat dissipation efficiency.
[0026] Furthermore, a filter screen may be provided at the gas groove 13 to prevent dust from entering the first gas channel 6 .
[0027] During demoulding, the second solenoid valve 14 is closed, the first solenoid valve 8 is opened, and the air supply operation of the pump body is controlled. The pump body transports gas to the inside of the square groove 5 through the second air cavity 11, the first gas channel 6 and the second gas channel 7, so that the slider 4 drives the top plate 3 to move upward, lifts the tray, and improves the demoulding efficiency.
[0028] After demoulding is completed, the pump body is controlled to perform a suction operation, and the pump body sucks the gas inside the square groove 5 through the second air cavity 11, the first gas channel 6 and the second gas channel 7, so that the top plate 3 is reset, and then the first solenoid valve 8 is closed.
