Description

Technical Field

[0001] This application relates to the field of automotive structure processing technology, and in particular to a molding die. Background Technology

[0002] Currently, the manufacturing process for radiator water chambers involves connecting upper and lower molds. Liquid raw materials for making the radiator water chamber are injected into the mold through a feeding port. The liquid material solidifies within the mold, forming the radiator water chamber. The mold for processing the radiator water chamber has a fixing structure. This fixing device needs to be manually placed in a designated position inside the upper and lower molds before connection. This ensures that the interface between the liquid material and the fixing structure naturally connects after solidification. Therefore, when the upper and lower molds are separated, the solidified radiator water chamber is connected to the fixing structure through the interface, ensuring the stability of the radiator water chamber's position. However, when removing the solidified radiator water chamber from the lower mold, the fixing structure must first be disengaged from the interface of the radiator water chamber and removed from the mold before the solidified radiator water chamber can be removed from the mold.

[0003] Currently, the operation to remove the fixing structure involves moving the fixing structure laterally relative to the interface of the radiator water chamber, causing the fixing structure to detach from the interface of the radiator water chamber, and then removing the radiator water chamber from the lower mold.

[0004] The existing fixing structure of the processing mold is complex and the size of the processing mold is large. It requires manual placement and removal of the fixing structure, which wastes manpower. There is also the possibility that manual operation may cause the fixing structure to be placed in the wrong position, resulting in damage to the mold. Utility Model Content

[0005] The purpose of this application is to address the above problems by providing a molding die that can quickly detach from the radiator water chamber and move rapidly between a first position and a second position, with stable positioning, requiring no manual operation, and improving production efficiency.

[0006] This application provides a molding die, characterized in that the molding die is used to process a radiator water chamber, the molding die comprising: a lower die capable of supporting the molded radiator water chamber, and the radiator water chamber being along the length direction of the lower die; at least one inclined ejector assembly, the inclined ejector assembly being slidably disposed on the upper surface of the lower die to reciprocate between a first position and a second position along the width direction of the lower die, the inclined ejector assembly including a limiting inclined rod; wherein, when the inclined ejector assembly is located in the first position, the connecting end of the limiting inclined rod is connected to the interface of the radiator water chamber, and when the inclined ejector assembly moves from the first position to the second position, the connecting end of the limiting inclined rod disengages from the interface of the radiator water chamber.

[0007] According to the technical solutions provided in certain embodiments of this application, the inclined top assembly further includes: a movable part, the movable part being slidably disposed on the upper surface of the lower mold, the movable part having an internal accommodating space, the side wall of the movable part having a moving channel extending to the accommodating space, and at least a portion of the moving channel coinciding with the accommodating space, the extending direction of the moving channel having a first angle with the width direction of the lower mold, at least a portion of the limiting inclined rod being located within the moving channel, when the inclined top assembly moves from the first position to the second position, the limiting inclined rod moves sequentially along the length direction of the lower mold and the width direction of the lower mold, so that the connecting end of the limiting inclined rod disengages from the interface of the radiator water chamber, wherein the distance the limiting inclined rod moves along the length direction of the lower mold is 1mm-4mm, and the first angle is 5° to 30°.

[0008] According to the technical solutions provided in certain embodiments of this application, the width of the moving channel is greater than the width of the portion of the limiting inclined rod located within the moving channel, so that the limiting inclined rod can move along the length direction of the lower mold within the moving channel.

[0009] According to the technical solutions provided in certain embodiments of this application, the lower surface of the movable member is provided with a mating groove, and the inclined top assembly further includes: a sliding member, at least a portion of which is located within the receiving space, the upper surface of which is provided with a protrusion, which is located within the mating groove, the size of which is larger than the size of which is larger, and when the inclined top assembly is located in the first position, the inner wall surface of which is facing the radiator water chamber abuts against the outer surface of which is facing away from the radiator water chamber.

[0010] According to the technical solutions provided in certain embodiments of this application, the upper surface of the lower mold is provided with a movable groove corresponding to the position of the movable part, the sliding part is disposed in the movable groove, and the lower surface of the horizontal section of the sliding part is provided with a snap-fit ​​groove. The inclined top assembly further includes: a limiting member, which is an L-shaped structure disposed in the movable groove, the limiting member is located below the movable part, and the upper surface of the horizontal section of the limiting member can engage and disengage with the snap-fit ​​groove; and an elastic member, which is disposed between the lower surface of the limiting member and the movable groove so that the limiting member can move in the vertical direction.

[0011] According to the technical solutions provided in certain embodiments of this application, the movable slot includes a connected sliding slot and a limiting slot. The depth of the limiting slot is greater than that of the sliding slot. The sliding slot is opened along the width direction of the lower mold, and the limiting slot is opened along the length direction of the lower mold. At least a portion of the limiting slot coincides with the sliding slot. The limiting member and the elastic member are both disposed in the limiting slot. The sliding member is an L-shaped structure that is slidably disposed in the sliding slot.

[0012] According to the technical solutions provided in certain embodiments of this application, the upper surface of the horizontal section of the sliding member is provided with the protrusion. When the inclined top assembly is located in the first position, there is a gap between the inner wall surface of the mating groove away from the radiator water chamber and the outer surface of the protrusion facing the radiator water chamber. When the inclined top assembly moves from the first position to the second position, the inner wall surface of the mating groove away from the radiator water chamber moves towards the outer wall surface of the protrusion facing the radiator water chamber.

[0013] According to the technical solutions provided in certain embodiments of this application, the lower surface of the movable member is provided with a pressing groove, the upper end face of the vertical section of the limiting member is higher than the upper surface of the horizontal section of the sliding member, the upper part of the vertical section of the limiting member is located in the pressing groove, and when the inclined top assembly moves from the first position to the second position, the pressing groove gradually abuts against the upper end of the vertical section of the limiting member, so that the limiting member moves downward and the horizontal section of the limiting member disengages from the locking groove.

[0014] According to the technical solutions provided in certain embodiments of this application, the pressing groove includes a horizontal groove and an inclined groove. The inclined groove is closer to the radiator water chamber than the horizontal groove, and the depth of the inclined groove gradually decreases from the second position to the first position.

[0015] According to the technical solutions provided in certain embodiments of this application, the top surface of the vertical section of the sliding member is provided with a slide rail along the length direction of the lower mold, and the lower surface of the limiting inclined rod located at one end of the moving channel is provided with a horizontal groove, the horizontal groove being opened along the length direction of the lower mold, and the horizontal groove slidingly engaging with the slide rail.

[0016] Compared with existing technologies, the beneficial effects of this application are as follows: The lower mold supports the radiator water chamber, and the inclined ejector assembly can reciprocate between a first position and a second position. This allows it to automatically move between the two positions to disengage from the radiator water chamber and return to its initial position after disengagement. This eliminates the need for manual operation, ensures stable positioning, and avoids mold damage caused by improper placement due to manual operation. Simultaneously, the reciprocating movement of the inclined ejector assembly between the first and second positions also improves production efficiency. Specifically, when the inclined ejector assembly is in the first position, the connecting end of the limiting angled rod is connected to the interface of the radiator water chamber, thus ensuring the stability of the radiator water chamber's position during processing. When the inclined ejector assembly moves from the first position to the second position, the connecting end of the limiting angled rod disengages from the interface of the radiator water chamber. This achieves rapid disengagement of the inclined ejector assembly from the processed radiator water chamber, facilitating removal and improving processing efficiency.

[0021] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this application.

[0022] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0023] As mentioned in the background section, current radiator water chamber manufacturing processes involve connecting upper and lower molds, then injecting the liquid material for the radiator water chamber into the mold through a feeding port. The liquid material solidifies within the mold to form the radiator water chamber. The mold contains a fixing structure, which needs to be manually placed in a designated position inside the upper and lower molds before connection. This ensures that the interface of the liquid material naturally connects with the fixing structure after solidification. Therefore, when the upper and lower molds are separated, the solidified radiator water chamber remains connected to the fixing structure through the interface, ensuring its positional stability. However, to remove the solidified radiator water chamber from the lower mold, the fixing structure must first be disengaged from the interface of the radiator water chamber and removed from the mold before the solidified radiator water chamber can be removed from the mold.

[0024] Currently, the operation to remove the fixing structure involves moving the fixing structure laterally relative to the interface of the radiator water chamber, causing the fixing structure to detach from the interface of the radiator water chamber, and then removing the radiator water chamber from the lower mold.

[0025] The existing fixing structure of the processing mold is complex and the size of the processing mold is large. It requires manual placement and removal of the fixing structure, which wastes manpower. There is also the possibility that manual operation may cause the fixing structure to be placed in the wrong position, resulting in damage to the mold.

[0026] Therefore, this application proposes a molding die 1000, such as Figures 1-3As shown, the forming mold 1000 is used to process the radiator water chamber 2000. The forming mold 1000 includes a lower mold 100 and at least one inclined ejector assembly 200. The lower mold 100 is capable of supporting the formed radiator water chamber 2000, and the radiator water chamber 2000 is along the length direction of the lower mold 100. The inclined ejector assembly 200 is slidably disposed on the upper surface of the lower mold 100 to reciprocate between a first position and a second position along the width direction of the lower mold 100. The inclined ejector assembly 200 includes a limiting inclined rod 210.

[0027] Specifically, when the inclined top assembly 200 is in the first position, the connecting end 211 of the limiting inclined rod 210 is connected to the interface 400 of the radiator water chamber 2000. When the inclined top assembly 200 moves from the first position to the second position, the connecting end 211 of the limiting inclined rod 210 gradually disengages from the interface 400 of the radiator water chamber 2000.

[0028] It should be noted that "at least one" means at least one. The molding die 1000 of this application includes at least one inclined ejector assembly 200. The molding die 1000 may also include multiple inclined ejector assemblies 200, depending on the interface of the radiator water chamber 2000.

[0029] The first position is where the connecting end 211 of the limiting angled rod 210 of the inclined ejector assembly 200 connects to the interface 400 of the radiator water chamber 2000. The second position is where the inclined ejector assembly 200 disengages from the radiator water chamber 2000 after moving away from the radiator water chamber 200 along the width direction of the lower mold 100.

[0030] In some embodiments of this application, such as Figures 1-4 As shown, the lower mold 100 provides the basic support for the entire structure. The radiator water chamber 2000 is arranged on it along its length. The inclined ejector assembly 200 achieves demolding by sliding. Specifically, this involves the connection and disengagement of the connecting end 211 of the limiting inclined rod 210 with the product interface 400. When it is necessary to remove the radiator water chamber 2000, the movement of the inclined ejector assembly 200 can precisely control the limiting inclined rod 210 to be pulled out from the interface 400 of the radiator water chamber 2000, which is convenient and quick. At the same time, the inclined ejector assembly 200 can reciprocate between the first and second positions, allowing it to disengage from the radiator water chamber 2000 and return to its initial position for use when processing the next radiator water chamber 2000.

[0031] This application proposes a molding die 1000, in which a lower die 100 supports a radiator water chamber 2000. An inclined ejector assembly 200 can reciprocate between a first position and a second position, automatically moving between these two positions to disengage from the radiator water chamber 2000 and returning to its initial position after disengagement. This eliminates the need for manual operation, ensures stable positioning, and avoids mold damage caused by improper placement due to manual operation. The reciprocating motion of the inclined ejector assembly 200 between the first and second positions also improves production efficiency. Specifically, when the inclined ejector assembly 200 is in the first position, the connecting end 211 of the limiting inclined rod 210 connects to the interface 400 of the radiator water chamber 2000, thus ensuring the stability of the radiator water chamber 2000's position during processing. As the inclined top assembly 200 moves from the first position to the second position, the connecting end 211 of the limiting inclined rod 210 gradually disengages from the interface 400 of the radiator water chamber 2000. This enables the inclined top assembly 200 to quickly disengage from the processed radiator water chamber 2000, facilitating the removal of the radiator water chamber 2000 and improving processing efficiency.

[0032] In some embodiments of this application, such as Figure 1 , Figure 4 and Figure 5 As shown, the inclined ejector assembly 200 also includes a movable member 220, which is slidably disposed on the upper surface of the lower mold 100. By pushing the movable member 220, the inclined ejector assembly 200 can reciprocate between a first position and a second position. The movement of the movable member 220 can be achieved by connecting to an external power structure.

[0033] like Figure 5 and Figure 6 As shown, the movable part 220 has an internal accommodating space 221, and the side wall of the movable part 220 has a moving channel 222 extending to the accommodating space 221, and at least a portion of the moving channel 222 overlaps with the accommodating space 221.

[0034] Therefore, when the limiting angle rod 210 is within the moving channel 222, at least a portion of the limiting angle rod 210 is also located within the receiving space 221. The extending direction of the moving channel 222 forms a first angle with the width direction of the lower mold 100, the first angle being... Figure 7 As shown by the angle α between the centerline L1 and the line L2, the extension direction of line L1 is the width direction of the lower mold 100, and the extension direction of line L2 is the extension direction of the moving channel 222 and the extension direction of the inclined rod portion of the limiting inclined rod 210. The first included angle is between 5° and 30°.

[0035] At least a portion of the limiting angle rod 210 is located within the moving channel 222, thereby enabling it to move within the moving channel 222. When the inclined top assembly 200 moves from the first position to the second position, the limiting angle rod 210 moves sequentially along the length direction and the width direction of the lower mold 100, so that the connecting end 211 of the limiting angle rod 210 disengages from the interface 400 of the radiator water chamber 2000.

[0036] Specifically, when the inclined ejector assembly 200 moves from the first position to the second position, the movable part 220 moves along the width direction of the lower mold 100 in a direction away from the radiator water chamber 2000. Then, the limiting rod 210 of the inclined ejector assembly 200 first moves along the length direction of the lower mold 100, which is the horizontal direction of the extension of the vertical line L1. The limiting rod 210 moves a distance of 1mm-4mm along the length direction of the lower mold 100, thereby disengaging the connecting end 211 of the limiting rod 210 from the interface 400 of the radiator water chamber 2000. When the inclined ejector assembly 200 continues to move from the first position to the second position, the limiting rod 210 moves synchronously with the movable part 220 in a direction away from the radiator water chamber 2000, thus achieving complete disengagement of the inclined ejector assembly 200 from the radiator water chamber 2000. This makes the operation convenient. After the inclined ejector assembly 200 is completely separated from the radiator water chamber 2000, the radiator water chamber 2000 can be easily removed. Then the inclined ejector assembly 200 returns from the second position to the first position, so that the inclined ejector assembly 200 does not need to be manually placed between the upper and lower molds.

[0037] In some embodiments of this application, such as Figure 7 As shown, the width of the moving channel 222 is greater than the width of the portion of the limiting rod 210 located within the moving channel 222, so that the limiting rod 210 can move along the length direction of the lower mold 100 within the moving channel 222.

[0038] Therefore, when the movable part 220 moves from the first position to the second position, the limiting inclined rod 210 can move along the length direction of the lower mold 100 within the moving channel 222, thereby disengaging the connecting end 211 from the interface 400 of the radiator water chamber 2000.

[0039] In other words, there is a width difference between the width of the moving channel 222 and the width of the limiting rod 210, and the width difference provides a clearance for the movement of the limiting rod 210 within the moving channel 222.

[0040] In some embodiments of this application, such as Figure 5 As shown, the lower surface of the movable part 220 has a mating groove 223, and the inclined top assembly 200 also includes a sliding part 230, at least a portion of which is located within the receiving space 221. Figures 9-12As shown, the upper surface of the slider 230 is provided with a protrusion 231. For example... Figure 5 As shown, the protrusion 231 is located inside the mating groove 223.

[0041] The size of the mating groove 223 is larger than the size of the protrusion 231, meaning the length of the mating groove 223 is greater than the length of the protrusion 231. When the inclined top assembly 200 is in the first position, the inner wall surface of the mating groove 223 facing the radiator water chamber 2000 abuts against the outer surface of the protrusion 231 facing away from the radiator water chamber 2000. There is a gap between the surface of the protrusion 231 facing the radiator water chamber 2000 and the inner wall surface of the mating groove 223 facing away from the radiator water chamber 2000. In other words, when the movable part 220 starts to move from the first position to the second position, there is a free travel between the mating groove 223 and the protrusion 231. Therefore, when the movable part 220 continues to move towards the second position, the mating groove 223 will eventually abut against the protrusion 231, causing the sliding part 230 to move.

[0042] In some embodiments of this application, such as Figures 9-12 As shown, the top surface of the vertical section of the sliding member 230 is provided with a slide rail 233 along the length direction of the lower mold 100, and the lower surface of the limiting inclined rod 210 located at one end of the moving channel 222 is provided with a horizontal groove 212. The horizontal groove 212 is opened along the length direction of the lower mold 100, and the horizontal groove 212 slides in cooperation with the slide rail 233.

[0043] Specifically, such as Figures 9-12 As shown, when the movable part 220 moves from the first position to the second position, the sliding engagement of the slide rail 233 and the transverse groove 212 provides precise guidance for the linear movement of the limiting inclined rod 210 along its length. This guiding mechanism ensures that the connecting end 211 disengages from the interface 400 when the limiting inclined rod 210 moves along the length direction of the lower mold 100. The movement trajectory is precise and error-free, without deflection or jamming. This further ensures that the connecting end 211 can accurately and smoothly disengage from the interface 400 of the radiator water chamber 2000, improving the accuracy and reliability of the entire demolding action. Subsequently, through the connection between the slide rail 233 and the transverse groove 212, the movable part 220 can drive the limiting inclined rod 210 to move synchronously along the width direction of the lower mold 100 to completely disengage from the interface 400.

[0044] In some embodiments of this application, such as Figure 3 As shown, the upper surface of the lower mold 100 has a movable slot 110 corresponding to the position of the movable part 220. For example... Figure 2 As shown, the slider 230 is disposed within the movable slot 110, as... Figure 9As shown, the lower surface of the horizontal section of the sliding member 230 has a locking groove 232. The inclined top assembly 200 also includes a limiting member 240 and an elastic member. The limiting member 240 is an L-shaped structure disposed in the movable slot 110. The limiting member 240 is located below the movable member 220, and the upper surface of its horizontal section can engage and disengage with the locking groove 232. The elastic member is disposed between the lower surface of the limiting member 240 and the movable slot 110 to allow the limiting member 240 to move in the vertical direction.

[0045] Specifically, the limiting member 240 and the elastic member constitute an automatic locking and unlocking mechanism. When the inclined ejector assembly 200 moves to the first position, under the elastic force of the elastic member, the horizontal section of the limiting member 240 engages upward into the locking groove 232 of the sliding member 230, locking the position of the sliding member 230 and preventing accidental movement when not in operation, thus ensuring stability during the molding process. When demolding is required, the external driving force overcomes the elastic force, causing the limiting member 240 to move downward, disengaging it from the locking groove 232 and unlocking it, thereby allowing the sliding member 230 to move from the first position to the second position. The elastic member can be a spring.

[0046] In some embodiments of this application, such as Figure 3 As shown, the movable slot 110 includes a connected sliding slot 111 and a limiting slot 112. The depth of the limiting slot 112 is greater than that of the sliding slot 111. Therefore, when the sliding member 230 and the limiting member 240 are located in the movable slot, the limiting member 240 is located below the sliding member 230. The sliding slot 111 is opened along the width direction of the lower mold 100, and the limiting slot 112 is opened along the length direction of the lower mold 100. At least a portion of the limiting slot 112 coincides with the sliding slot 111. The limiting member 240 and the elastic member are both disposed in the limiting slot 112. The sliding member 230 is an L-shaped structure that is slidably disposed in the sliding slot 111.

[0047] In some embodiments of this application, such as Figure 3 As shown, the design of the movable slot 110 optimizes the spatial layout. The sliding slot 111 guides the sliding component 230 to slide along the width direction of the lower mold 100. The deeper limiting slot 112 not only provides space for the vertical movement of the limiting component 240, but also reserves a position for the installation of the elastic component. This partitioned design allows multiple functional units such as sliding, limiting, and elastic reset to be integrated into a compact space, with clear structural layers and no interference between them, greatly improving the structural rationality and maintenance convenience of the mold.

[0048] In some embodiments of this application, such as Figures 9-12As shown, the upper surface of the horizontal section of the sliding member 230 is provided with a protrusion 231. When the inclined top assembly 200 is in the first position, there is a gap between the inner wall surface of the mating groove 223 away from the radiator water chamber 2000 and the outer surface of the protrusion 231 facing the radiator water chamber 2000. When the inclined top assembly 200 moves from the first position to the second position, the inner wall surface of the mating groove 223 away from the radiator water chamber 2000 moves towards the outer wall surface of the protrusion 231 facing the radiator water chamber 2000.

[0049] In some embodiments of this application, such as Figures 9-12 As shown, there is a gap between the inner wall surface of the mating groove 223 facing away from the radiator water chamber 2000 and the outer surface of the protrusion 231 facing the radiator water chamber 2000. This gap can adjust the movement mode of the limiting rod 210 during the movement of the movable member 220 from the first position to the second position. That is, this gap allows the movable member 220 to move independently a certain distance in the initial stage of its movement from the first position to the second position. During this stage, the sliding member 230 is temporarily stationary because it is blocked by the limiting member 240, and the gap gradually decreases as the movable member 220 moves until the inner wall surface of the mating groove 223 facing away from the radiator water chamber 2000 contacts the outer surface of the protrusion 231 facing the radiator water chamber 2000. Thus, in the later stage of the movement of the movable member 220 from the first position to the second position, the sliding member 230 can move synchronously by abutting against the protrusion 231 through the mating groove 223. The interval mentioned above is the "idle stroke". During the idle stroke phase, the limiting rod 210 moves along the length of the lower mold 100 to disengage from the interface 400.

[0050] In some embodiments of this application, such as Figures 6-8 As shown, the lower surface of the movable member 220 is provided with a pressing groove 224. The height of the upper end of the vertical section of the limiting member 240 is higher than the height of the upper surface of the horizontal section of the sliding member 230. The upper part of the vertical section of the limiting member 240 is located in the pressing groove 224. When the inclined top assembly 200 moves from the first position to the second position, the pressing groove 224 gradually abuts against the upper end of the vertical section of the limiting member 240, so that the limiting member 240 moves downward and the horizontal section of the limiting member 240 disengages from the locking groove 232.

[0051] In some embodiments of this application, such as Figures 6-8As shown, the engagement between the pressing groove 224 and the upper part of the limiting member 240 enables an automatic unlocking function. During demolding, when the movable member 220 moves to a specific position, the top wall of the pressing groove 224 begins to contact and press down on the upper end of the vertical section of the limiting member 240. Because the upper end of the limiting member 240 is higher, it can be triggered by the pressing groove 224 of the movable member 220 and pressed down on the limiting member 240. The downward pressure overcomes the elastic force of the elastic member, forcing the overall height of the limiting member 240 to decrease, causing its horizontal section to disengage from the locking groove 232 of the sliding member 230, thereby releasing the lock on the sliding member 230. The entire process requires no additional power or operation, achieving precise timing control and efficient automated demolding.

[0052] In some embodiments of this application, such as Figures 6-8 As shown, the pressing groove 224 includes a horizontal groove 10 and an inclined groove 20. The inclined groove 20 is closer to the radiator water chamber 2000 than the horizontal groove 10. The depth of the inclined groove 20 gradually decreases from the second position to the first position.

[0053] Specifically, such as Figures 6-8 As shown, the special shape design of the pressing groove 224 optimizes the unlocking process. The horizontal groove 10 provides clearance for the limiting member 240 in the initial stage of movement, ensuring that unlocking is not triggered prematurely. The inclined surface design of the inclined groove 20 makes the downward pressure of the moving part 220 on the limiting member 240 a gradual process, rather than an instantaneous impact. This smooth transition reduces impact and wear between parts, making the unlocking action smoother and more reliable, and helping to extend the service life of the mold.

[0054] At the same time, such as Figure 9 and Figure 12 As shown, the top surface of the vertical section of the limiting member 240 can also be an arc surface whose height gradually decreases from the second position to the first position. Thus, the top surface of the vertical section of the limiting member 240 can better transition from the horizontal groove 10 of the pressing groove 224 to the inclined groove 20, making the overall pressing process smoother.
