Description

Technical Field

[0001] The present application relates to the technical field of mold parts, and more specifically, to a preform removal device and a preform mold. Background Art

[0002] A preform mold is generally composed of a core plate, a separator plate, and a cavity plate. The core plate and the separator plate serve as a movable mold plate, and the cavity plate serves as a fixed mold plate. The movable mold plate is combined with the fixed mold plate to form one or more mold cavities. The preform manufacturing melt is injected into the mold cavity through the runner under high pressure. The preform manufacturing melt in the mold cavity is cooled and formed into a preform.

[0003] After the preform is formed and the mold is opened, a robotic arm removes the preform from the mold and places it on a conveyor belt for transport to the next workstation. Existing robotic arms typically have a fixed preform removal device, which removes the preforms using suction via multiple preform removal cylinders. However, existing preform removal cylinders typically have a one-to-one correspondence with mold cavities. This means that each preform removal cylinder must be activated each time the preform is removed. Consequently, residual heat from the previous, previous, or previous previous preform is often retained by each cylinder. This can cause the preform to overheat and deform due to contact with the cylinders, and also slows the preform molding cycle.

[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a preform removal device and a preform mold to solve the problem that each preform removal cylinder of the preform removal device has to work every time the preform is removed by the preform removal device. In this way, when the preform removal cylinder takes the preform, residual heat of the previous, the previous, or even the previous previous preform is often retained. This not only causes the preform to overheat and easily contact and deform with the preform removal cylinder, but also slows down the molding cycle of the preform.

[0006] To achieve the above objectives, the technical solution adopted in the first embodiment of the present application is:

[0007] A blank taking device, comprising:

[0008] Take the blank plate;

[0031] The present application sets up multiple groups of blank taking cooling cylinder modules, each group of blank taking cooling cylinder modules can take one bottle blank, so that multiple groups of blank taking cooling cylinder modules can take multiple bottle blanks, that is, multiple bottle blanks can be made at the same time. The blank taking device of the present application can improve the manufacturing efficiency of bottle blanks, and the present application sets up several blank taking cooling cylinders corresponding to a mold cavity, so that after one of the blank taking cooling cylinders in the same group takes out the bottle blank in the mold cavity, another blank taking cooling cylinder in the group can be replaced to take out the next bottle blank, so that the blank taking cooling cylinder that has taken out the bottle blank is cooled. When multiple blank taking cooling cylinders are set up in the same group, the unit time for each group of blank taking cooling cylinders to take out the bottle blank is extended, which not only does not affect the blank taking efficiency of the blank taking device, shortens the cooling and molding cycle of the bottle blank, but also is beneficial to the cooling of the blank taking cooling cylinder, thereby preventing the bottle blank from overheating and contacting and deforming the blank taking cooling cylinder.

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

"Multiple" means two or more, unless otherwise clearly and specifically defined.

[0046] After the preform is formed and the mold is opened, a robotic arm removes the preform from the mold and places it on a conveyor belt for transport to the next workstation. Existing robotic arms typically have a fixed preform removal device, which removes the preforms using suction via multiple preform removal cylinders. However, existing preform removal cylinders typically have a one-to-one correspondence with mold cavities. This means that each preform removal cylinder must be activated each time the preform is removed. Consequently, residual heat from the previous, previous, or previous previous preform is often retained by each cylinder. This can cause the preform to overheat and deform due to contact with the cylinders, and also slows the preform molding cycle.

[0047] For this purpose, see Figure 1 and Figure 2 The first aspect of the embodiment of the present application provides a blank removal device, comprising a blank removal plate 1 and multiple groups of blank removal cooling cylinder modules 2, wherein the multiple groups of blank removal cooling cylinder modules 2 are arranged on the side of the blank removal plate 1 close to the mold cavity, wherein each group of the blank removal cooling cylinder modules 2 includes a plurality of blank removal cooling cylinders 21, and all the blank removal cooling cylinders 21 in the same group of blank removal cooling cylinder modules 2 are arranged on the blank removal plate 1 and correspond to the same mold cavity, and all the blank removal cooling cylinders 21 in the same group of blank removal cooling cylinder modules 2 are used to remove the bottle blanks in the same mold cavity in a certain order.

[0048] In this embodiment, multiple groups of blank taking cooling cylinder modules 2 are provided, and each group of blank taking cooling cylinder modules 2 can take one bottle blank. In this way, multiple groups of blank taking cooling cylinder modules 2 can take multiple bottle blanks, that is, multiple bottle blanks can be made at the same time. The blank taking device of this embodiment can improve the manufacturing efficiency of bottle blanks. In addition, in this embodiment, multiple blank taking cooling cylinders 21 are provided in correspondence with a mold cavity. In this way, after one blank taking cooling cylinder 21 in the same group takes out the bottle blank in the mold cavity, another blank taking cooling cylinder 21 in the same group can be replaced to take out the next bottle blank, so that the blank taking cooling cylinder 21 that has taken out the bottle blank is cooled. When multiple blank taking cooling cylinders 21 are provided in the same group, the unit time for each group of blank taking cooling cylinders 21 to take out the bottle blank is extended, which not only does not affect the blank taking efficiency of the blank taking device, shortens the cooling and molding cycle of the bottle blank, but also is beneficial to the cooling of the blank taking cooling cylinder 21, thereby preventing the bottle blank from being overheated and deformed by contact with the blank taking cooling cylinder 21.

[0049] Optional, see Figure 1 In one embodiment, the blank removal plate 1 includes a base plate 11 and a mounting plate 12, the mounting plate 12 is arranged on the base plate 11, and multiple groups of the blank removal cooling cylinder modules 2 are arranged on the side of the mounting plate 12 away from the base plate 11.

[0050] Since the blank taking cooling cylinder 21 is provided with a cooling water path and an air path (for air suction), and the cooling water path and the air path on the blank taking cooling cylinder 21 need to be introduced from the blank taking plate 1 through the outside, this embodiment arranges the blank taking plate 1 into a separate bottom plate 11 and a mounting plate 12, which is not only convenient for processing, but also beneficial for when the cooling water path and the air path introduced from the blank taking plate 1 leak, only the bottom plate 11 or the mounting plate 12 needs to be replaced according to the leakage location, which can save material maintenance costs.

[0051] In order to ensure that the position of the blank removing cooling cylinder 21 of the blank removing device is facing the bottle blank in the mold cavity, and to ensure that the bottle blank can smoothly enter the corresponding blank removing cooling cylinder 21, the position of the blank removing device needs to be calibrated when the mold is installed.

[0052] Optional, see Figure 2 and Figure 5 In one embodiment, a plurality of hollowed-out grooves 111 are provided on the bottom plate 11. This embodiment not only reduces the weight of the blank plate 1 but also helps save material costs by providing a plurality of hollowed-out grooves 111 on the bottom plate 11.

[0053] Optional, see Figure 4 In one embodiment, the blank taking device further includes a plurality of auxiliary correction rods 3. The blank taking plate 1 is provided with a plurality of first correction holes (not shown in the figure), and the cavity plate is provided with second correction holes (not shown in the figure) that match the first correction holes. The auxiliary correction rods 3 are used to be inserted into the first correction holes and the second correction holes corresponding thereto. It is understandable that after the mold and the blank taking device are installed, the blank taking plate 1 is moved to the blank taking position, and then the auxiliary correction rods 3 are inserted into the first correction holes of the blank taking plate 1 and the second correction holes of the cavity plate. In this way, the position of the blank taking device can be corrected, thereby ensuring the position accuracy of the blank taking device. After the correction, the auxiliary correction rods 3 can be removed. It is understandable that the auxiliary correction rods 3 are only used for the first calibration when using the blank taking device, and the position can be adjusted accordingly according to the program settings.

[0054] Optional, see Figure 1 and Figure 2 In one embodiment, the blank taking device further includes a pad 4, which is arranged on the side of the bottom plate 11 away from the mounting plate 12. By providing the pad 4, this embodiment can raise the blank taking plate 1, thereby solving the problem that when the bottle blank is long, the thickness of the mold increases to exceed the position of the blank taking plate 1 of the machine, resulting in the blank taking plate 1 possibly interfering with the mold when taking the blank.

[0055] Optional, see Figure 2 、 Figure 3 、 Figure 6 and Figure 7In one embodiment, the blank removal device further includes a positioning sleeve 5, a first bolt 6, and a second bolt 7. The positioning sleeve 5 is disposed between the base plate 11 and the backing plate 4. A first mounting step 51 and a second mounting step 52 are formed on both sides of the positioning sleeve 5. The first bolt 6 is disposed within the first mounting step 51, and the second bolt 7 is disposed within the second mounting step 52 to secure the base plate 11 and the backing plate 4. By providing the positioning sleeve 5, the first bolt 6, and the second bolt 7, this embodiment not only ensures the position of the blank removal plate 1 (blank removal device), but also secures the base plate 11 and the backing plate 4.

[0056] There are two of each of the positioning sleeve 5 , the first bolt 6 and the second bolt 7 .

[0057] Optional, see Figure 4 In one embodiment, the blank removal device further includes a gasket 8, which is disposed at the screw through-hole of the mounting plate 12. In this embodiment, by disposing the gasket 8, when connected by screws, the screws do not directly contact the mounting plate 12, but directly contact the gasket 8. In this way, when the screw through-hole is deformed, it will only act on the gasket 8, thereby protecting the mounting plate 12 (blank removal plate 1). It is foreseeable that when the gasket 8 is deformed by the screw through-hole, it can be directly replaced with the gasket 8. Compared with replacing the entire mounting plate 12, replacing the gasket 8 is more cost-effective.

[0058] Optionally, in one embodiment, the blank taking plate 1 is configured as an aluminum plate.

[0059] Optional, see Figure 8 and Figure 9 In one embodiment, since the material of the blank taking plate 1 is aluminum plate, the hardness is not high, and the screw hole 112 connected to the machine is easily deformed and damaged. In order to prevent the screw thread from being damaged, the blank taking device also includes a plurality of screw sleeves 9. A plurality of screw holes 112 are opened at the place where the base plate 11 is connected to the machine, and a plurality of the screw sleeves 9 are respectively arranged in the corresponding screw holes 112. In this embodiment, by adding screw sleeves 9 in the screw holes 112, the screw holes 112 are protected from being damaged due to repeated assembly and disassembly of the mold.

[0060] The screw sleeve 9 can be configured as a pin screw sleeve or a wire screw sleeve.

[0061] To sum up, the present application provides a blank removal device and a bottle blank mold, comprising a blank removal plate 1 and multiple groups of blank removal cooling cylinder modules 2, wherein the multiple groups of blank removal cooling cylinder modules 2 are arranged on the side of the blank removal plate 1 close to the mold cavity, wherein each group of the blank removal cooling cylinder modules 2 includes a plurality of blank removal cooling cylinders 21, and all the blank removal cooling cylinders 21 in the same group of blank removal cooling cylinder modules 2 are arranged on the blank removal plate 1 and correspond to the same mold cavity, and all the blank removal cooling cylinders 21 in the same group of blank removal cooling cylinder modules 2 are used to remove the bottle blanks in the same mold cavity in a certain order. The present application sets up multiple groups of blank taking cooling cylinder modules 2, and each group of blank taking cooling cylinder modules 2 can take one bottle blank. In this way, multiple groups of blank taking cooling cylinder modules 2 can take multiple bottle blanks, that is, multiple bottle blanks can be made at the same time. The blank taking device of the present application can improve the manufacturing efficiency of bottle blanks. In addition, the present application sets up several blank taking cooling cylinders 21 corresponding to a mold cavity. In this way, after one of the blank taking cooling cylinders 21 in the same group takes out the bottle blank in the mold cavity, another blank taking cooling cylinder 21 in the group can be replaced to take out the next bottle blank, so that the blank taking cooling cylinder 21 that has taken out the bottle blank is cooled. When multiple blank taking cooling cylinders 21 are set up in the same group, the unit time for each group of blank taking cooling cylinders 21 to take out the bottle blank is extended, which not only does not affect the blank taking efficiency of the blank taking device, shortens the cooling and molding cycle of the bottle blank, but also is beneficial to the cooling of the blank taking cooling cylinder 21, thereby preventing the bottle blank from overheating and contacting and deforming the blank taking cooling cylinder 21.

[0062] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
