Description

Technical Field

[0001] This application relates to the field of membrane manufacturing equipment technology, and more specifically, to a die head opening and closing tooling. Background Technology

[0002] In the existing technology, the manufacturing of film materials such as thin films requires the use of a die head. After a period of use, the die head needs to be cleaned and maintained. However, when using existing die head auxiliary devices for die head cleaning, there is a problem of poor matching between the die head and the die head auxiliary device. Summary of the Invention

[0003] The purpose of this application is to provide a die head opening and closing fixture that can improve the problem of poor matching between the die head and the die head auxiliary device.

[0004] The embodiments of this application are implemented as follows:

[0005] This application provides a die head opening and closing fixture, including a fixture body and a die head fixing assembly. The die head fixing assembly includes an mounting part and a fixing part; the fixing part is connected to the fixture body, and the mounting part and the fixing part are detachably connected; the mounting part is provided with a mounting hole for mounting the die head.

[0006] In the above technical solution, the mounting holes are used to connect the mold head to the mold head fixing assembly. The mounting and fixing components are designed to be detachable, so when cleaning mold heads of different widths and irregular shapes, only the mounting component needs to be replaced according to the size of the mold head, thus improving the problem of poor compatibility between the mold head and the mold head auxiliary device.

[0007] In some alternative embodiments, the fastener has a first groove on the side away from the tooling body, and the mounting part includes a mounting part body and a first protrusion. The first protrusion is located on the side of the mounting part body near the fastener and is detachably embedded in the first groove.

[0008] In the above technical solution, the first groove and the first protrusion cooperate with each other, which can quickly realize the disassembly and assembly of the mounting parts and the fixing parts, thereby improving the efficiency of mold head replacement.

[0009] In some alternative implementations, the first groove penetrates the fastener in a first direction, which is the axial direction of the mounting hole; a second groove is provided on the side of the first groove near the tooling body, the second groove communicates with the first groove, and the second groove is formed on the fastener along the height direction of the fastener;

[0010] The mounting component also includes a second protrusion, which is located on the side of the first protrusion away from the mounting component body, and the second protrusion is detachably embedded in the second groove;

[0011] Furthermore, in the height direction of the fastener, the ratio of the size of the first groove to the height of the fastener is (3-6):10;

[0012] Furthermore, in the first direction, the ratio of the size of the second groove to the size of the fastener is (3-5):10.

[0013] In the above technical solution, the fixing component has a second groove, and the mounting component has a corresponding second protrusion. The detachable engagement of the second groove and the second protrusion enhances the connection stability between the mounting component and the fixing component, thereby improving safety during mold cleaning. Furthermore, limiting the opening dimensions of the first and second grooves also helps to increase the connection stability between the mounting component and the fixing component.

[0014] In some alternative embodiments, the fastener has a first fixing hole along a first direction, and / or the fastener has a second fixing hole along the height direction of the fastener; the mounting member has holes corresponding to the first fixing hole and / or the second fixing hole.

[0015] In the above technical solution, the fastener is provided with a first fixing hole and a second fixing hole, and corresponding holes are opened on the mounting component. The mounting component and the fastener can be connected together by fasteners passing through the fixing holes and holes, which can further increase the connection stability of the mounting component and the fastener.

[0016] In some alternative embodiments, the fastener has a plurality of first fixing holes distributed along a second direction, the second direction being perpendicular to the first direction and the height direction of the fastener, and / or the fastener has a plurality of second fixing holes distributed along the second direction.

[0017] In the above technical solution, multiple first and second fixing holes are provided to offer better stability; in addition, the first and second fixing holes are distributed along the second direction, which facilitates the layout of the fixing holes.

[0018] In some alternative embodiments, the mounting element has a plurality of mounting holes along the second direction, and the mounting holes and the second fixing holes are staggered along the second direction.

[0019] In the above technical solution, the mounting component is provided with multiple mounting holes, which can increase the connection stability between the mold head and the mounting component; the mounting holes are distributed along the second direction, which facilitates the layout of the mounting holes; the mounting holes and the second fixing hole are staggered, so that there is an appropriate distance between any two adjacent mounting holes, which can further increase the connection stability between the mold head and the mounting component.

[0020] In some alternative implementations, the tooling body includes a frame and a support assembly, the support assembly being provided in two sets and disposed on the frame along a first direction, and at least one set of support assemblies being slidably connected to the frame along the first direction;

[0021] Furthermore, the support assembly includes a first support and a second support. The first support is fixedly connected to the frame, and the second support is slidably connected to the frame along a second direction. A mold head fixing assembly is provided on the side of the support assembly away from the frame.

[0022] In the above technical solution, at least one set of support components is slidably connected to the frame along the first direction. When cleaning molds of different lengths, the position of the support components can be adjusted to match the mold opening and closing fixture with the molds of different lengths, thereby further increasing the compatibility between the mold and the mold opening and closing fixture. In addition, the first support is fixedly connected to the frame, and the second support is slidably connected to the frame along the second direction. The position of the second support can be adjusted to separate the molds located on the support components. This setting not only prevents the molds from colliding, but also facilitates the cleaning work of the cleaning personnel.

[0023] In some alternative implementations, the tooling body also includes a limiting rod, one end of which is rotatably connected to the first bracket, and a limiting element is provided on the side of the limiting rod near the second bracket;

[0024] Furthermore, the limiting component is a limiting groove, and the second bracket is provided with a limiting protrusion corresponding to the limiting groove.

[0025] In the above technical solution, the tooling body is equipped with a limiting rod, which can simultaneously fix the relative positions of the two supports in each set of support components after the mold head is separated, so that there is a suitable gap between the two parts of the mold head after separation, thereby improving the convenience of mold head cleaning. In addition, a limiting element is provided at the end of the limiting rod near the second support, which makes it easier to realize the fixing function of the limiting rod. Furthermore, the limiting element is set as a limiting groove, and a corresponding limiting protrusion is provided on the second support. When the second support moves to the set position, the limiting rod can move under its own gravity and the limiting groove and the limiting protrusion can cooperate, thereby realizing the function of automatic limiting and fixing.

[0026] In some alternative embodiments, the tooling body further includes a support base connected to both sides of the bracket assembly in a second direction. The fastener is rotatably connected to the bracket assembly, such that the die head fixing assembly has a first position and a second position. When the die head fixing assembly is in the first position, it is located on the side of the bracket assembly away from the frame. When the die head fixing assembly is in the second position, it is located on the side of the support base away from the frame.

[0027] In the above technical solution, the fixing component and the bracket assembly are rotatably connected, so that the die head fixing assembly can drive the die head to rotate, thereby facilitating the cleaning of the die head; the tooling body is provided with a support seat, so that when the die head rotates to the set position, it can bear the load of the die head, thereby increasing the stability of the die head opening and the overall structure of the tooling.

[0028] In some alternative implementations, the die head opening and closing fixture also includes a positioning block, which is detachably connected to the bracket assembly near the die head fixing assembly and abuts against the fixing member when the die head fixing assembly is in the second position.

[0029] In the above technical solution, by setting a positioning block and making the positioning block and the bracket assembly detachably connected, the mold head fixing assembly can be fixed by abutting the fixing member when the mold head fixing assembly is in the second position, thereby fixing the mold head in the set position and ensuring the safety of the mold head during cleaning.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] It should be noted that the terms "and / or" in this application, such as "feature 1 and / or feature 2", all refer to the three cases of "feature 1" alone, "feature 2" alone, and "feature 1" plus "feature 2".

[0041] In the description of this application, it should be noted that the terms "upper," "lower," "vertical," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] Furthermore, the term "vertical" does not mean that the component must be absolutely vertical, but rather that it can be slightly tilted. For example, "vertical" simply means that its direction is more horizontal than "horizontal," and does not mean that the structure must be perfectly vertical.

[0043] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In the prior art, when cleaning molds of different widths and irregular shapes, in order to match the molds of different widths and irregular shapes, the mold auxiliary device mainly adopts the method of setting multiple mounting holes of different specifications in the mold mounting part. However, under this matching method, a mold auxiliary device can only be matched with a limited number of molds, that is, there is still a problem of poor matching between the mold and the mold auxiliary device, which greatly reduces the utilization rate of the mold auxiliary device.

[0045] The inventors discovered that by making the structure for mounting the mold head in the mold head auxiliary device detachable, the problem of poor compatibility between the mold head and the mold head auxiliary device can be solved by simply switching the size of the mounting structure according to the size of the mold head when dealing with mold heads of different widths and irregular shapes.

[0046] See Figure 1 This application provides a mold head opening and closing fixture 10, including a fixture body 100 and a mold head fixing assembly 200. The mold head fixing assembly 200 includes an mounting member 210 and a fixing member 220. The fixing member 220 is connected to the fixture body 100, and the mounting member 210 is detachably connected to the fixing member 220. The mounting member 210 is provided with a mounting hole 211 for mounting the mold head.

[0047] In this application, the mounting hole 211 is provided to connect the mold head to the mold head fixing assembly 200. The mounting member 210 and the fixing member 220 are designed to be detachable, so that when cleaning mold heads of different widths and irregular shapes, only the mounting member 210 needs to be replaced according to the size of the mold head to improve the problem of poor matching between the mold head and the mold head auxiliary device.

[0048] It should be noted that, considering the efficiency of mold head replacement, the structure of the mold head fixing component 200 can be adjusted.

[0049] See Figure 2As an example, the fastener 220 has a first groove 221 on the side away from the tooling body 100, and the mounting part 210 includes a mounting part body 212 and a first protrusion 213. The first protrusion 213 is located on the side of the mounting part body 212 near the fastener 220, and the first protrusion 213 is detachably embedded in the first groove 221.

[0050] In this embodiment, the first groove 221 and the first protrusion 213 cooperate with each other, which can quickly realize the disassembly and assembly of the mounting part 210 and the fixing part 220, thereby improving the replacement efficiency of the mold head.

[0051] The inventors discovered that, considering the connection stability of the mounting component 210 and the fixing component 220, the structure of the mold head fixing assembly 200 can also be adjusted.

[0052] As an example, the first groove 221 penetrates the fastener 220 in the first direction a, where the first direction a is the axial direction of the mounting hole 211; the first groove 221 is provided with a second groove 222 on the side near the tooling body 100, the second groove 222 communicates with the first groove 221, and the second groove 222 is opened on the fastener 220 along the height direction c of the fastener; the mounting member 210 also includes a second protrusion 214, which is provided on the side of the first protrusion 213 away from the mounting member body 212, and the second protrusion 214 is detachably embedded in the second groove 222.

[0053] In this embodiment, the fixing member 220 is provided with a second groove 222, and the mounting member 210 is provided with a corresponding second protrusion 214. The detachable cooperation of the second groove 222 and the second protrusion 214 can help increase the connection stability of the mounting member 210 and the fixing member 220, thereby improving the safety during mold cleaning.

[0054] It should be noted that the second groove 222 being formed along the height direction c of the fastener 220 means that the second groove 222 can be formed on either side of the fastener 220 or at any position in the middle of the fastener 220, that is, the second groove 222 is located inside the fastener 220.

[0055] To further increase the connection stability between the mounting component 210 and the fixing component 220, a plurality of second grooves 222 can be provided on the fixing component 220 along the first direction a. That is, the second grooves 222 can be provided on both sides of the fixing component 220 at the same time, or on either side of the fixing component 220 and the middle part of the fixing component 220 at the same time; the mounting component 210 is provided with a plurality of second protrusions 214 corresponding to the second grooves 222.

[0056] As an example, in the height direction c of the fastener, a second groove 222 is formed on one side of the fastener 220.

[0057] The inventors discovered that, considering the stability of the structure of the fastener 220 itself and the overall structure of the mold head fixing assembly 200, the dimensions of the first groove 221 and the second groove 222 can be adjusted.

[0058] As an example, in the height direction c of the fastener, the size ratio of the first groove 221 to the height of the fastener 220 is (3-6):10, for example, but not limited to any one of the ratios 3:10, 4:10, 5:10 and 6:10 or any range between the two; in the first direction a, the size ratio of the second groove 222 to the size of the fastener 220 is (3-5):10, for example, but not limited to any one of the ratios 3:10, 4:10 and 5:10 or any range between the two.

[0059] In this embodiment, the dimensions of the first groove 221 and the second groove 222 are respectively limited so that the first groove 221 and the second groove 222 have a suitable proportion in the mold head fixing assembly 200, which can ensure the stability of the fixing member 220 itself and further ensure the stability of the overall structure of the mold head fixing assembly 200.

[0060] It should be noted that when there are multiple second grooves 222, the ratio of the size of the second groove 222 to the size of the fastener 220 in the first direction a is (3~5):10, which means that the sum of the sizes of the multiple second grooves 222 in the first direction a is (3~5):10 to the size of the fastener 220.

[0061] The inventors discovered that, in order to further enhance the structural stability of the mounting component 210 and the fixing component 220, the structure of the mounting component 210 and the fixing component 220 can be adjusted.

[0062] As an example, the fastener 220 has a first fixing hole 223 along the first direction a, and / or the fastener 220 has a second fixing hole 224 along the height direction c of the fastener; the mounting member 210 has a hole 215 corresponding to the first fixing hole 223 and / or the second fixing hole 224.

[0063] In this embodiment, the fastener 220 is provided with a first fixing hole 223 and a second fixing hole 224, and a corresponding hole 215 is opened on the mounting member 210. By fastening fasteners passing through the fixing holes and the hole 215, the mounting member 210 and the fastener 220 can be connected together, which can further increase the connection stability of the mounting member 210 and the fastener 220.

[0064] It is understood that the specific connection method of the mounting component 210 and the fastener 220 is not limited, and can be set according to the conventional form in this field.

[0065] As an example, both the first fixing hole 223 and the second fixing hole 224 are threaded holes, that is, the fastener is a bolt, and the mounting part 210 and the fixing part 220 are connected by bolts.

[0066] Based on this, in order to provide better structural stability for the connection between the mounting part 210 and the fastener 220, the number of each type of fixing hole can be adjusted.

[0067] As an example, the fastener 220 has a plurality of first fixing holes 223, which are distributed along a second direction b, which is perpendicular to the first direction a and the height direction c of the fastener, and / or the fastener 220 has a plurality of second fixing holes 224, which are distributed along the second direction b.

[0068] In this embodiment, multiple first fixing holes 223 and second fixing holes 224 are provided to offer better stability. Furthermore, the first fixing holes 223 and the second fixing holes 224 are distributed along the second direction b, which facilitates the layout of the fixing holes.

[0069] As an example, the number of the first fixing hole 223 and the second fixing hole 224 is set to 2 to 4, for example, but not limited to any one of 2, 3 and 4.

[0070] The inventors discovered that, in order to further enhance the connection stability between the mold head and the mounting part 210, the number of mounting holes 211 can be adjusted.

[0071] As an example, the mounting member 210 has a plurality of mounting holes 211 along the second direction b, and the mounting holes 211 and the second fixing hole 224 are staggered along the second direction b.

[0072] In this embodiment, the mounting component 210 is provided with multiple mounting holes 211, which can increase the connection stability between the mold head and the mounting component 210; the mounting holes 211 are distributed along the second direction b, which facilitates the layout of the mounting holes 211; the mounting holes 211 and the second fixing hole 224 are staggered, so that there is a suitable distance between any two adjacent mounting holes 211, which can further increase the connection stability between the mold head and the mounting component 210.

[0073] As an example, the number of mounting holes 211 is 2.

[0074] The inventors discovered that, in order to further increase the compatibility between the mold head and the mold head opening and closing tooling 10 and to facilitate cleaning work, the structure of the tooling body 100 can be adjusted.

[0075] As an example, the tooling body 100 includes a frame 110 and a support assembly 120. The support assembly 120 is provided in two sets and is disposed on the frame 110 along the first direction a. At least one set of support assemblies 120 is slidably connected to the frame 110 along the first direction a.

[0076] Furthermore, the support assembly 120 includes a first support 121 and a second support 122. The first support 121 is fixedly connected to the frame 110, and the second support 122 is slidably connected to the frame 110 along the second direction b. A mold head fixing assembly 200 is provided on the side of the support assembly 120 away from the frame 110.

[0077] In this embodiment, at least one set of support assemblies 120 is slidably connected to the frame 110 along the first direction a. When cleaning molds of different lengths, the position of the support assembly 120 can be adjusted to match the mold opening and closing fixture 10 with the molds of different lengths, thereby further increasing the compatibility between the mold and the mold opening and closing fixture 10. In addition, the first support 121 is fixedly connected to the frame 110, and the second support 122 is slidably connected to the frame 110 along the second direction b. The position of the second support 122 can be adjusted to separate the molds located on the support assembly 120. This arrangement not only prevents the molds from colliding, but also facilitates the cleaning work of the cleaning personnel.

[0078] It should be noted that "at least one set of support components 120" can refer to one set of support components 120 or two sets of support components 120.

[0079] As an example, a set of support components 120 are slidably connected to the frame 110 along a first direction a.

[0080] It is understandable that the specific form of the sliding connection is not limited; it can be set as a linear guide or a linear ball screw, etc.

[0081] As an example, the sliding connection takes the form of a linear guide rail.

[0082] It should be noted that, in order to prevent damage to the mold head during mold head merging, the structure of the support assembly 120 can be adjusted.

[0083] As an example, the first support 121 is provided with a buffer limiter on the side near the second support 122.

[0084] In this embodiment, the buffer limiter can reduce the impact force between the mold heads when they are joined, thereby protecting the mold heads.

[0085] It is understandable that the material of the buffer limiter is not specifically limited and can be selected according to the conventional materials in this field.

[0086] As an example, the buffer limiter is made of polyurethane.

[0087] Based on this, in order to further improve the convenience of cleaning work, the structure of the tooling body 100 can be adjusted.

[0088] See Figure 3 and Figure 4 As an example, the tooling body 100 also includes a limiting rod 130, one end of which is rotatably connected to the first bracket 121, and a limiting member 131 is provided at the end of the limiting rod 130 near the second bracket 122.

[0089] In this embodiment, the tooling body 100 is provided with a limiting rod 130, which can fix the relative position of the two supports in each set of support assemblies 120 after the mold head is separated, so that there is a suitable gap between the two parts of the mold head after separation, thereby improving the convenience of mold head cleaning work; in addition, a limiting member 131 is provided at one end of the limiting rod 130 near the second support 122, and the setting of the limiting member 131 makes it easier to realize the fixing function of the limiting rod 130.

[0090] It should be noted that the specific form of the limiting member 131 is not limited. The limiting member 131 can be set as L-shaped or hook-shaped. It can be understood that as long as the side of the limiting member 131 near the second bracket 122 can abut against the second bracket 122 to achieve the limiting and fixing function, it is acceptable.

[0091] Based on this, and considering the convenience of the limiting and fixing function, the form of the limiting component 131 can be adjusted.

[0092] As an example, the limiting member 131 is a limiting groove, and the second bracket 122 is provided with a limiting protrusion 1221 corresponding to the limiting groove.

[0093] In this embodiment, the limiting member 131 is set as a limiting groove, and the second bracket 122 is provided with a corresponding limiting protrusion 1221. When the second bracket 122 moves to the set position, the limiting rod 130 can move under its own gravity and the limiting groove and the limiting protrusion 1221 can cooperate, thereby realizing the function of automatic limiting and fixing.

[0094] It should be noted that the structure of the limit rod 130 can be adjusted to further improve its convenience.

[0095] As an example, the end of the limiting rod 130 near the first bracket 121 is positioned above the end near the second bracket 122.

[0096] In this embodiment, the limiting rod 130 is inclined downward. When the second bracket 122 reaches the set position, the limiting member 131 on the limiting rod 130 can match the limiting protrusion 1221 more quickly and conveniently, thereby further improving the convenience of the limiting rod 130.

[0097] The inventors discovered that, considering the ease of cleaning the mold head and the overall stability of the mold head opening and closing fixture 10, the structure of the fixture body 100 can also be adjusted.

[0098] See Figure 4 As an example, the tooling body 100 also includes a support base 140. In the second direction b, the support base 140 is connected to both sides of the bracket assembly 120. The fixing member 220 is rotatably connected to the bracket assembly 120, so that the die head fixing assembly 200 has a first position and a second position. When the die head fixing assembly 200 is in the first position, the die head fixing assembly 200 is located on the side of the bracket assembly 120 away from the frame 110. When the die head fixing assembly 200 is in the second position, the die head fixing assembly 200 is located on the side of the support base 140 away from the frame 110.

[0099] In this embodiment, the fixing member 220 is rotatably connected to the bracket assembly 120, so that the mold head fixing assembly 200 can drive the mold head to rotate, thereby facilitating mold head cleaning; the tooling body 100 is provided with a support seat 140, so that when the mold head rotates to the set position, it can bear the mold head, thereby increasing the stability of the overall structure of the mold head opening and closing tooling 10.

[0100] It should be noted that the support base 140 is connected to both sides of the bracket assembly 120, meaning that the support base 140 is provided on both sides of the first bracket 121 away from the second bracket 122 and on both sides of the second bracket 122 away from the first bracket 121.

[0101] Furthermore, the fact that the mold head fixing component 200 is located on one side of the bracket assembly 120 means that the mold head fixing component 200 is provided on both the first bracket 121 and the second bracket 122.

[0102] The inventors also discovered that the rotation angle can be adjusted to further increase the convenience of cleaning the mold head.

[0103] As an example, the rotation angle range is 0 to 180°, such as, but not limited to, any one of the angles 0°, 30°, 60°, 90°, 120°, 150° and 180° or any range between two of them.

[0104] Based on this, in order to prevent damage to the mold head during position changes, the structure of the support base 140 can be adjusted.

[0105] As an example, when the die head fixing assembly 200 is in the second position, the support base 140 is provided with a buffer pad on the side near the die head fixing assembly 200.

[0106] Understandably, there are no specific restrictions on the material of the cushioning pad; it can be selected according to the conventional materials used in this field.

[0107] As an example, the cushioning pad is made of polyurethane.

[0108] In this embodiment, the buffer pad can reduce the impact force between the die head fixing assembly 200 and the support base 140, thereby protecting the die head.

[0109] The inventors discovered that, considering the safety during mold head cleaning, the structure of the mold head opening and closing fixture 10 can be adjusted.

[0110] See Figure 4 As an example, the mold head opening and closing fixture 10 also includes a positioning block 300. When the mold head fixing assembly 200 is in the second position, the positioning block 300 is detachably connected to the bracket assembly 120 on the side near the mold head fixing assembly 200 and abuts against the fixing member 220.

[0111] In this embodiment, a positioning block 300 is provided and the positioning block 300 and the bracket assembly 120 are detachably connected. When the mold head fixing assembly 200 is in the second position, the mold head fixing assembly 200 can be fixed by abutting the fixing member 220, thereby fixing the mold head in the set position and ensuring the safety of the mold head during cleaning.

[0112] It should be noted that the detachable connection between the positioning block 300 and the bracket assembly 120 near the mold head fixing assembly 200 and the fixing member 220 means that when the mold head fixing assembly 200 is in the first position, the fixing member 220 and the bracket assembly 120 near the mold head fixing assembly 200 are not connected, and when the mold head fixing assembly 200 is in the second position, the fixing block 300 and the bracket assembly 120 are connected and abut against the mold head fixing assembly 200.

[0113] The inventors discovered that, considering the convenience of detachable connections and the stability of the connection, the connection method can be adjusted.

[0114] As an example, the bracket assembly 120 has a guide rail protrusion on the side near the mold head fixing assembly 200, the positioning block 300 has a corresponding groove on the side near the bracket assembly 120, and the bracket assembly 120 and the positioning block 300 have screw holes.

[0115] In this embodiment, guide rail protrusions and corresponding grooves are provided to facilitate quick disassembly and assembly of the positioning block 300. In addition, the bolt connection is used to enhance the connection stability between the positioning block 300 and the mold head fixing assembly 200.

[0116] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
