A grooved paper mold forming device

Abstract

This utility model relates to the technical field of grooved paper forming, and proposes a grooved paper mold forming device for forming grooved paper. It includes a fixed mold and a moving mold assembly disposed around the outer periphery of the fixed mold. The moving mold assembly includes several moving molds circumferentially spaced around the outer periphery of the fixed mold. Each moving mold has a driver connected to one side, which drives the corresponding moving mold to independently approach or move away from the fixed mold. Each moving mold moves towards the fixed mold, and the fixed mold and the moving mold assembly cooperate to form the grooved paper. At least two moving molds do not perform a reset or retraction action within a corresponding time period after the grooved paper is formed, so as to remain close to the fixed mold. The remaining moving molds reset and retract away from the fixed mold after the grooved paper is formed. Since two moving mold assemblies reset and move away from the fixed mold after the grooved paper is formed, while the remaining moving mold assemblies remain close to the fixed mold, the remaining moving mold assemblies maintain the forming of the grooved paper, preventing the grooved paper from scattering and detaching from the fixed mold after forming, thus improving forming accuracy.

Description

Technical Field

[0001] This utility model relates to the technical field of grooved paper forming, and specifically to a grooved paper mold forming device. Background Technology

[0002] In the motor manufacturing industry, stator slot paper is a key component of the overall insulation structure of a motor, and its quality directly affects the motor's service life and performance. The stator slot paper needs to be bent into specific shapes and dimensions during the forming process, often requiring high precision.

[0003] Existing slotted paper forming molds include a concave mold and a convex mold. The concave mold and convex mold cooperate to form the slotted paper. Initially, the convex mold is located away from the concave mold. When the concave mold is away from the convex mold, the outer circumference of the convex mold is open, making it inconvenient to install a heating device on the convex mold. Even if a heating device is installed on the convex mold, the heating time of the slotted paper by the convex mold during the paper forming process is relatively short, as the convex mold feeds the vertically positioned paper into the slot. Furthermore, after the concave mold and convex mold have cooperated to form the paper, a secondary forming mold is required above the convex mold to prevent the slotted paper from detaching from the convex mold. The structure is relatively complex and therefore requires further improvement. Utility Model Content

[0004] This invention proposes a slotted paper mold forming device. It comprises a fixed mold and several moving molds. The moving molds are circumferentially spaced along the outer periphery of the fixed mold, with four or more moving molds. Two moving molds are positioned opposite each other in the front-rear direction of the fixed mold, and the other two are positioned opposite each other in the left-right direction. The four moving molds are driven by corresponding drivers to move closer to the fixed mold, allowing the fixed mold and moving molds to cooperate in forming the slotted paper. Compared to the existing technology where the punch is initially far from the die and has a complex structure, this structure allows the moving molds to move towards the fixed mold from multiple directions, performing multi-directional forming operations on the slotted paper.

[0005] A grooved paper mold forming device designed for this purpose, used for forming grooved paper, includes a fixed mold and a moving mold group disposed on the outer periphery of the fixed mold. The moving mold group includes a plurality of moving molds that are circumferentially spaced and disposed on the outer periphery of the fixed mold.

[0006] Each moving mold is equipped with a driver connected to its transmission on one side. The driver drives the corresponding moving mold to move closer to or away from the fixed mold independently. Each moving mold moves towards the fixed mold. The fixed mold and the moving mold group cooperate to form the groove paper. At least two moving molds do not perform a reset or retraction action within the corresponding time period after the groove paper is formed, so as to keep close to the fixed mold. All other actions are reset and retraction away from the fixed mold after the groove paper is formed.

[0007] The grooved paper mold forming device also includes a heating device for heating the fixed mold, which is located below the fixed mold.

[0008] The heating device includes a heating seat with a built-in heating element, and a connecting seat fixedly connected to the fixed mold on the heating seat. The heating seat is detachably installed on the slotted paper mold forming device; or, the connecting seat is detachably installed on the heating seat.

[0009] The heating base is equipped with a temperature detector for detecting its heating temperature, and the detection end of the temperature detector is in thermal contact with the heating base.

[0010] The moving module includes a front groove and a rear punch that are arranged in opposite directions on the outer periphery of the fixed mold. The fixed mold is located between the front groove and the rear punch. During the groove forming process, the front groove and the rear punch move closer to the fixed mold, and after the groove forming is completed, the front groove and the rear punch return to their initial state away from the fixed mold.

[0011] The front groove is provided with limiting blocks on the left and right sides for limiting the paper. The paper is limited on the front groove by the limiting blocks.

[0012] The driver includes a first cylinder that is drivenly connected to the front groove. The piston rod of the first cylinder is provided with a connecting plate that is detachably connected to the front groove. Fasteners are provided between the front groove and the connecting plate. The front groove is detachably mounted on the connecting plate by means of fasteners.

[0013] The driver includes a second cylinder that is drivenly connected to the rear punch. The piston rod of the second cylinder is provided with a mounting seat that is connected to the rear punch. A locking member is provided between the mounting seat and the piston rod of the second cylinder. One end of the piston rod of the second cylinder is provided with a first locking groove that is horizontally inserted into the mounting seat. The locking member is vertically inserted into the mounting seat and engages with the first locking groove to prevent the piston rod of the second cylinder from disengaging from the mounting seat. When the locking member disengages from the mounting seat, the piston rod of the second cylinder disengages from the mounting seat, thereby separating the rear punch from the second cylinder.

[0014] The moving module includes a first side forming mold and a second side forming film arranged at intervals on the outer periphery of the fixed mold. The fixed mold is located between the first side forming mold and the second side forming film. The first side forming mold and the second side forming film remain close to the fixed mold during the corresponding time period after the groove paper is formed.

[0015] The actuator includes a third cylinder. The piston rod of the third cylinder is provided with an assembly seat that is connected to the side forming mold. A locking member is provided between the assembly seat and the piston rod of the third cylinder. One end of the piston rod of the third cylinder is provided with a second locking groove that is laterally inserted into the assembly seat. The locking member is vertically inserted into the assembly seat and engages with the second locking groove to prevent the piston rod of the third cylinder from disengaging from the assembly seat. When the locking member disengages from the assembly seat, the piston rod of the third cylinder disengages from the assembly seat, thereby separating the side forming mold from the third cylinder.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] By setting a fixed mold and several moving molds, the moving molds are arranged circumferentially at intervals along the outer periphery of the fixed mold, with a total of four or more moving molds. Two moving molds are arranged opposite each other in the front-back direction of the fixed mold, and the other two moving molds are arranged opposite each other in the left-right direction of the fixed mold. The four moving molds are driven by corresponding drivers to move closer to the fixed mold, so that the fixed mold and moving molds cooperate to form the groove paper. Compared with the problem of the punch being far away from the die and the complex structure in the prior art, this structure allows the moving mold group to move closer to the fixed mold from multiple directions to perform multi-directional forming operation on the groove paper. Two of the moving molds move away from the fixed mold to reset after the groove paper is formed, while the remaining moving molds remain close to the fixed mold for a corresponding period of time after the groove paper is formed. Therefore, the remaining moving molds maintain the forming of the groove paper, preventing the groove paper from spreading out and detaching from the fixed mold after forming, thus improving the forming accuracy. This avoids the inconvenience of setting up heating devices due to the open state of the outer periphery of the punch in the existing technology, as well as the problem of needing to set up a secondary forming mold. It simplifies the mold structure, reduces the complexity and manufacturing difficulty of the mold, and helps to improve production efficiency and the practicality of the mold.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-11 A grooved paper mold forming device for forming grooved paper 4 includes a fixed mold 1 and a moving mold group 2 disposed on the outer periphery of the fixed mold 1. The moving mold group 2 includes a plurality of moving molds that are circumferentially spaced on the outer periphery of the fixed mold 1.

[0031] Each moving mold is provided with a driver 3 connected to it on one side. The driver 3 drives the corresponding moving mold to move closer to or away from the fixed mold 1 independently. Each moving mold moves towards the fixed mold 1. The fixed mold 1 cooperates with the moving mold group 2 to form the groove paper 4. At least two moving molds do not perform a reset or retraction action within the corresponding time period after the groove paper 4 is formed, so as to keep close to the fixed mold 1. The remaining actions are reset and retraction away from the fixed mold 1 after the groove paper 4 is formed.

[0032] By setting a fixed mold 1 and several moving molds, the moving molds are arranged circumferentially at intervals along the outer periphery of the fixed mold 1, with more than four moving molds. Two moving molds are arranged opposite each other in the front-back direction of the fixed mold 1, and the other two moving molds are arranged opposite each other in the left-right direction of the fixed mold 1. The four moving molds are driven by corresponding drivers 3 to move closer to the fixed mold 1, so that the fixed mold 1 and the moving molds cooperate to form the grooved paper 4. Compared with the problem of the punch being far away from the die and the structure being complex in the initial state of the prior art, this structure allows the moving mold group 2 to move closer to the fixed mold 1 from multiple directions to perform multi-directional forming operations on the grooved paper 4. Two of the moving molds move away from the fixed mold 1 to reset after the grooved paper 4 is formed, while the remaining moving molds remain close to the fixed mold 1 for a corresponding period of time after the grooved paper 4 is formed. Therefore, the remaining moving molds maintain the forming of the grooved paper 4, preventing the grooved paper 4 from spreading out and detaching from the fixed mold 1 after forming, thus improving the forming accuracy. This avoids the inconvenience of setting up heating devices due to the open state of the outer periphery of the punch in the existing technology, as well as the problem of needing to set up a secondary forming mold. It simplifies the mold structure, reduces the complexity and manufacturing difficulty of the mold, and helps to improve production efficiency and the practicality of the mold.

[0033] The slotted paper mold forming device also includes a heating device 5 for heating the fixed mold 1, which is located below the fixed mold 1. When the slotted paper 4 is formed, as two of the moving mold groups 2 move away from the slotted paper 4, the remaining moving mold groups 2 remain close to the fixed mold 1. Therefore, the fixed mold 1 and the remaining moving mold groups 2 maintain the forming of the slotted paper 4. The heating device continues to heat the slotted paper 4 during the time when two of the moving mold groups 2 move away from the slotted paper 4, facilitating the pushing of the formed slotted paper 4 into the slot of the motor stator. Therefore, the heating device 5 can continuously and stably heat the fixed mold 1, maintaining a suitable temperature during the forming process of the slotted paper 4, thus fully heating the slotted paper 4, improving its forming performance, and solving the problems of inconvenient heating device placement and insufficient heating time in the prior art, thereby improving the functionality and reliability of the mold.

[0034] The heating device 5 includes a heating seat 5.1 with a built-in heating element 5.2. The heating seat 5.1 is provided with a connecting seat 6 that is fixedly connected to the fixed mold 1. The heating seat 5.1 is detachably installed on the slotted paper mold forming device; or, the connecting seat 6 is detachably installed on the heating seat 5.1.

[0035] This detachable installation method offers significant advantages. The heating seat 5.1 is detachably mounted on the grooved paper mold forming device. When the heating device 5 malfunctions or needs replacement, it can be quickly and easily disassembled and installed, facilitating daily maintenance and reducing downtime caused by equipment failure, thus improving production efficiency. Simultaneously, the detachable structure allows the heating seat 5.1 or connecting seat 6 to be replaced or adjusted according to different production needs, enhancing the mold's versatility and adaptability. This enables the forming of grooved paper 4 with different specifications and requirements, reducing mold usage and replacement costs.

[0036] In this embodiment, the grooved paper mold forming device includes a tooling base plate 8, a heating seat 5.1 is detachably mounted on the tooling base plate 8 by bolts, and a connecting seat 6 can be fixed to the heating seat 5.1 by welding, or the connecting seat 6 can be detachably mounted on the heating seat 5.1 by bolts.

[0037] In this embodiment, each driver 3 is a cylinder, and part of the cylinder body is fixed on a mounting base, which is fixed to the tooling base plate 8 by bolts.

[0038] The heating base 5.1 is equipped with a temperature detector 5.3 for detecting its heating temperature, and the detection end of the temperature detector 5.3 is in thermal contact with the heating base 5.1. The temperature detector 5.3 can accurately detect the temperature of the heating base 5.1 in real time, thereby enabling real-time monitoring and precise control of the heating status of the heating device 5. Based on the temperature signal fed back by the temperature detector 5.3, the heating power of the heating element 5.2 can be adjusted in a timely manner to keep the temperature of the heating base 5.1 within the set optimal range, avoiding the impact of excessively high or low temperatures on the forming quality of the grooved paper 4.

[0039] In this embodiment, the heating base 5.1 is provided with a first receiving groove for mounting the heating element 5.2 and a second receiving groove for mounting the temperature detector 5.3. The heating element 5.2 and the temperature detector 5.3 are respectively provided with fixing blocks, which are fixed on the outside of the heating base 5.1 to prevent the heating element 5.2 and the temperature detector 5.3 from detaching from the heating base 5.1.

[0040] The moving module 2 includes a front groove 2.1 and a rear punch 2.2 that are arranged in opposite directions on the outer periphery of the fixed mold 1. The fixed mold 1 is located between the front groove 2.1 and the rear punch 2.2. During the forming process of the groove paper 4, the front groove 2.1 and the rear punch approach the fixed mold 1 respectively. After the groove paper 4 is formed, the front groove 2.1 and the rear punch 2.2 are reset to their initial state away from the fixed mold 1.

[0041] The moving module 2 includes a front groove 2.1 and a rear punch 2.2, which are arranged opposite each other on the outer periphery of the fixed mold 1. The fixed mold 1 is located between the two, and the front groove 2.1 and the rear punch 2.2 move closer to the fixed mold 1 during the forming process of the grooved paper 4, and return to their initial state after forming. This front-to-back moving module structure can perform forming operations on the grooved paper 4 from both front and rear directions, so that the grooved paper 4 is simultaneously squeezed and formed on both the front and rear sides of the fixed mold 1. After forming, the front groove 2.1 and the rear punch 2.2 return to their original positions, which facilitates the removal of the grooved paper 4 and the next feeding.

[0042] The front groove 2.1 is provided with limiting blocks 7 on the left and right sides for limiting the paper. The paper is limited on the front groove 2.1 by the limiting blocks 7.

[0043] The front groove 2.1 is used to feed vertically positioned paper to the fixed mold 1. Limiting blocks 7 are provided on both the left and right sides of the front groove 2.1 to limit the paper's position. The limiting blocks 7 precisely position the paper left and right, preventing lateral deviation during feeding and ensuring the paper smoothly enters the position between the fixed mold 1 and the front groove 2.1. This avoids forming deviations and increased scrap rates caused by inaccurate paper positioning. It also ensures the paper 4 maintains a stable position during feeding, thereby improving product quality and production stability.

[0044] The driver 3 includes a first cylinder 3.1 that is drivenly connected to the front groove 2.1. The piston rod of the first cylinder 3.1 is provided with a connecting plate 3.11 that is detachably connected to the front groove 2.1. A fastener 3.12 is provided between the front groove 2.1 and the connecting plate 3.11. The front groove 2.1 is detachably mounted on the connecting plate 3.11 through the fastener 3.12.

[0045] See Figure 3 The actuator 3 includes a first cylinder 3.1 that is driven by the front groove 2.1. The piston rod of the first cylinder 3.1 has a connecting plate 3.11 that is detachably connected to the front groove 2.1. The front groove 2.1 and the connecting plate 3.11 are connected by fasteners 3.12. This detachable connection allows the front groove 2.1 to be quickly replaced according to different requirements for forming the grooved paper 4. When producing grooved paper 4 of different specifications or shapes, only the fasteners 3.12 need to be removed and the corresponding front groove 2.1 replaced, without requiring large-scale adjustments to the entire actuator 3 or mold structure, thus improving the versatility and flexibility of the mold. Simultaneously, the first cylinder 3.1, as a driving device, provides a stable and controllable driving force, allowing the front groove 2.1 to smoothly approach or move away from the fixed mold 1, ensuring the stability and reliability of the forming process, improving production efficiency and the forming quality of the grooved paper 4, and reducing the difficulty and time cost of manually changing molds.

[0046] In this embodiment, a cutter cylinder 9 is provided below the first cylinder 3.1. The piston rod of the cutter cylinder 9 is provided with a transmission plate 10 connected to the cutter. When the paper is conveyed to the front of the front groove 2.1 by the conveying device, the cutter cylinder 9 drives the first cylinder 3.1 and the front groove 2.1 to move towards the fixed mold 1 to cut the paper. The top of the transmission plate 10 is provided with a first slider 11, and the bottom of the connecting plate 3.11 is provided with a first slide rail 12 that cooperates with the first slider 11. The first cylinder 3.1 is fixed on the sliding plate 13 by a corresponding connector. The bottom of the sliding plate 13 is provided with a second slider. The top of the tooling base plate 8 is provided with a second slide rail that slides with the second slider. The first cylinder 3.1 is fixed on the top of the tooling base plate 8, and the bottom of the transmission plate 10 is fixed on the sliding plate 13.

[0047] See Figures 4-6 The driver 3 includes a second cylinder 3.2 that is drivenly connected to the rear punch 2.2. The piston rod of the second cylinder 3.2 is provided with a mounting seat 3.21 that is connected to the rear punch 2.2. A locking member 3.23 is provided between the mounting seat 3.21 and the piston rod of the second cylinder 3.2. One end of the piston rod of the second cylinder 3.2 is provided with a first locking groove that is horizontally inserted into the mounting seat 3.21. The locking member 3.23 is vertically inserted into the mounting seat 3.21 and cooperates with the first locking groove to prevent the piston rod of the second cylinder 3.2 from disengaging from the mounting seat 3.21. When the locking member 3.23 disengages from the mounting seat 3.21, the piston rod of the second cylinder 3.2 disengages from the mounting seat 3.21, thereby separating the rear punch 2.2 from the second cylinder 3.2.

[0048] In this embodiment, the second cylinder 3.2 is fixed on the top of the tooling base plate 8. A fixing plate 3.24 is provided on one side of the mounting base 3.21. The fixing plate 3.24 has a mounting groove for mounting the rear punch 2.2. The fixing plate 3.24 and the rear punch 2.2 are assembled through a T-slot. A third slide rail is provided on one side of the fixing plate 3.24. A first slider fixing seat 3.25 for fixing the third slider is provided on the top of the tooling base plate 8. The third slider slides in cooperation with the third slide rail. The first slider fixing seat 3.25 is fixed to the tooling base plate 8 by screw removal. When the rear punch 2.2 needs to be replaced, the locking piece 3.23 is disengaged from the mounting base 3.21, the piston rod of the second cylinder 3.2 is disengaged from the mounting base 3.21, and then the screws between the tooling base plate 8 and the first slider fixing seat 3.25 are removed. In this way, the second cylinder 3.2 does not need to be disassembled, and the entire rear punch 2.2 can be disassembled onto the tooling base plate 8.

[0049] The locking element 3.23 is vertically inserted into the mounting base 3.21 and engages with the first locking groove, effectively preventing the piston rod of the second cylinder 3.2 from disengaging from the mounting base 3.21. This ensures a secure and reliable connection between the rear punch 2.2 and the second cylinder 3.2 during the molding process, preventing molding failures and equipment damage caused by piston rod disengagement. When it is necessary to replace the rear punch 2.2 or perform equipment maintenance, simply disengage the locking element 3.23 from the mounting base 3.21 to allow the piston rod of the second cylinder 3.2 to disengage from the mounting base 3.21, achieving rapid separation of the rear punch 2.2 from the second cylinder 3.2. This simple and quick operation improves the maintenance efficiency and convenience of the equipment. This structural design ensures the stability of the transmission process and facilitates subsequent maintenance and replacement, enhancing the practicality and reliability of the mold.

[0050] See Figures 7-8 The moving module 2 includes a first side forming mold 2.3 and a second side forming film 2.4 arranged on the outer periphery of the fixed mold 1 in a left-right opposing manner. The fixed mold 1 is located between the first side forming mold 2.3 and the second side forming film 2.4. The first side forming mold 2.3 and the second side forming film 2.4 always remain close to the fixed mold 1 during the corresponding time period after the groove paper 4 is formed.

[0051] The moving module 2 includes a first side forming mold 2.3 and a second side forming film 2.4, which are arranged at a left-right interval on the outer periphery of the fixed mold 1, and both remain close to the fixed mold 1 for a corresponding period of time after the groove paper 4 is formed. This left-right facing side forming mold structure, which remains close to the fixed mold 1 for a corresponding period of time after the groove paper 4 is formed, can continuously apply pressure to the groove paper 4 from both sides after the groove paper 4 is formed, ensuring the shape of the left and right sides of the groove paper 4, preventing the groove paper 4 from easily spreading out after the front and rear molds move away from the fixed mold 1, and avoiding forming deviations caused by the partial repositioning or movement away from the fixed mold of the moving module. At the same time, it eliminates the need for secondary forming after the initial forming, as in the prior art, shortening the production cycle.

[0052] When the grooved paper 4 is formed, it is pushed upward by the push rod below the fixed mold 1 into the groove of the motor stator. Only then do the first side forming mold 2.3 and the second side forming film 2.4 perform a reset and retraction action, ready for the next forming of the grooved paper 4. The fixed mold 1 is provided with a push rod groove that cooperates with the push rod. The heating seat 5.1 and the connecting seat 6 are provided with through grooves corresponding to the push rod. One end of the push rod is connected to the push cylinder for transmission. The paper pushing structure can be seen in the paper pushing device disclosed in Chinese Patent Publication No. CN114389421A, which includes a telescopic cylinder, a floating joint plate, a push rod sliding plate, a push rod drive block, a push rod mounting block, a push rod guide block, and a push rod. Therefore, the paper pushing structure is prior art and will not be described in detail here.

[0053] The actuator 3 includes a third cylinder 3.3. The piston rod of the third cylinder 3.3 is provided with an assembly seat 3.31 that is connected to the side forming mold. A locking member 3.32 is provided between the assembly seat 3.31 and the piston rod of the third cylinder 3.3. One end of the piston rod of the third cylinder 3.3 is provided with a second locking groove that is laterally inserted into the assembly seat 3.31. The locking member 3.32 is vertically inserted into the assembly seat 3.31 and cooperates with the second locking groove to prevent the piston rod of the third cylinder 3.3 from disengaging from the assembly seat 3.31. When the locking member 3.32 disengages from the assembly seat 3.31, the piston rod of the third cylinder 3.3 disengages from the assembly seat 3.31, thereby separating the side forming mold from the third cylinder 3.3.

[0054] In this embodiment, a mounting plate 3.33 is provided on one side of the assembly base 3.31. The mounting plate 3.33 is used to fix the corresponding side forming mold. The side forming mold and the mounting plate 3.33 are connected by a T-slot. A fourth slide rail is provided on the mounting plate 3.33. A second slider fixing seat 3.36 for installing the fourth slider is provided on the tooling base plate 8. The second slider fixing seat 3.36 is fixed to the tooling base plate 8 by screw removal.

[0055] When it is necessary to replace the side forming mold, the locking part 3.32 is disengaged from the mounting base 3.31, the piston rod of the third cylinder 3.3 is disengaged from the mounting base 3.31, and then the screws between the tooling base plate 8 and the second slider fixing seat 3.36 are removed. In this way, the third cylinder 3.3 does not need to be disassembled, and the entire set of side forming molds can be disassembled onto the tooling base plate 8.

[0056] The actuator 3 includes a third cylinder 3.3. The piston rod of the third cylinder 3.3 is connected to the side forming mold via a mounting base 3.31 and a locking member 3.32. The locking member 3.32 is vertically inserted into the mounting base 3.31 and engages with the second locking groove, effectively preventing the piston rod of the third cylinder 3.3 from disengaging from the mounting base 3.31. This ensures a stable and reliable connection between the side forming mold and the third cylinder 3.3 during the forming process, guaranteeing the effective transmission of driving force and enabling the side forming mold to accurately perform forming operations on both sides of the slotted paper 4. When it is necessary to replace the side forming mold or perform equipment maintenance, simply disengage the locking member 3.32 from the mounting base 3.31 to separate the piston rod of the third cylinder 3.3, thereby allowing the side forming mold to be quickly separated from the third cylinder 3.3 for easy replacement and maintenance. This structural design ensures the stability and reliability of the transmission, while also improving the versatility and ease of maintenance of the equipment. It can adapt to the replacement needs of side forming dies of different specifications, reduce downtime during production, lower maintenance costs, and improve the overall performance and production efficiency of the mold.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
