Description

Technical Field

[0001] This application relates to the field of casting equipment technology, and in particular to a mold opening and closing trolley. Background Technology

[0002] Mold opening and closing trolleys are critical equipment in manufacturing, especially for the transportation, storage, and maintenance of large molds (such as plastic injection molds, die-casting molds, and composite material molding molds). However, these traditional mold opening and closing trolleys have some significant technical drawbacks in practical applications: the sliding pairs of the support components are constantly exposed to the working environment. Especially in foundry and injection molding workshops, residual material falling from the mold (such as flash and granules) easily intrudes into the gaps of the sliding pairs, leading to increased sliding resistance and problems such as jamming and accelerated wear. This not only affects the smoothness and positioning accuracy of the trolley's opening and closing action but also significantly shortens the service life of critical moving parts, increasing maintenance costs and downtime. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an opening and closing mold trolley that can effectively alleviate the problem of external impurities intruding, ensure smooth operation of the trolley, reduce wear, extend service life and reduce maintenance costs.

The shielding member is located above the movable pair and is used to shield the movable pair. Each movable pair is provided with a corresponding discharge chute, which is used to collect waste material.

[0005] In some embodiments, the support component includes: An adapter that can be detachably connected to one half of the mold; A support member, wherein the support member and the adapter are detachably connected, and the support member and the base are movably connected.

[0006] In some embodiments, the support member includes a support portion and a rolling portion, the support portion and the rolling portion being connected, and the rolling portion and the base assembly engaging in a rolling fit.

[0007] In some embodiments, the base assembly includes: A carrier member having a groove extending along a first direction, a rolling part located in the groove, and the rolling part and the groove engaging in a roller-like cooperation; wherein, a blocking member is disposed on the carrier member, the rolling part is located between the blocking member and the groove, and a discharge chute is disposed on the carrier member.

[0008] In some embodiments, the discharge chute is located in the chute and extends through the bottom of the chute.

[0009] In some embodiments, the base assembly further includes a limiting member, one end of the groove is configured as an open end, the limiting member and the carrier are detachably connected, the limiting member is at least partially located at the open end, and is used to limit the rolling part so that it is located within the groove.

[0010] In some embodiments, the support assembly further includes a locking member connected to the support member, the locking member being capable of locking the position of the support member in the first direction.

[0011] In some embodiments, the locking member includes a insertion groove and an insertion portion, the insertion portion passing through the insertion groove, the insertion groove being disposed on the support member, the carrier member having a plurality of insertion holes, the plurality of insertion holes being spaced apart along the first direction, the plurality of insertion holes being located on the movement path of the insertion portion, and the insertion portion being selectively inserted into one of the insertion holes.

[0012] In some embodiments, the top of the carrier has a bearing end face, the support has a sliding end face, the bearing end face and the sliding end face are respectively arranged parallel to the first direction, and the sliding end face and the bearing end face are slidably engaged.

[0013] In some embodiments, the adapter and the support are rotatably connected, and the rotation axis of the adapter is perpendicular to the bearing end face.

[0014] In some embodiments, the bottom of the support member is formed with a plurality of support legs.

[0015] The embodiments of this application have the following advantages: This application provides a mold opening and closing trolley. The base module includes a base assembly with a discharge groove and a blocking member located above the sliding joint. The support module includes multiple pairs of opposing support assemblies in a first direction for fixing the mold half. During operation, the support assemblies move along the base assembly in the first direction to form a sliding joint. The blocking member continuously covers the top of the sliding joint to prevent impurities such as flash and granular material from falling directly into the sliding gap. Impurities near the sliding joint are collected and discharged in real time through the discharge groove below the sliding joint, avoiding impurity accumulation that could cause jamming or wear. By combining physical blocking with active discharge, the cleanliness and smooth movement of the sliding joint are ensured.

[0016] Therefore, the shielding component directly blocks the space above the sliding pair, preventing impurities from falling into the sliding gap at the source and significantly reducing the risk of contamination. The discharge chute collects and removes residual impurities in a timely manner, avoiding increased sliding resistance and ensuring smooth opening and closing movements and accurate positioning. The clean working environment of the sliding pair effectively alleviates abnormal wear and extends the service life of key moving parts (such as guide rails and sliders). It reduces the frequency of downtime and maintenance needs caused by jamming or wear, improves equipment availability, and significantly reduces overall operation and maintenance costs.

[0026] In related technologies, mold opening and closing trolleys are key equipment in manufacturing, especially for the transportation, storage, and maintenance of large molds (such as plastic injection molds, die-casting molds, and composite material molding molds). However, these traditional mold opening and closing trolleys have some obvious technical defects in practical applications: the sliding pairs of the support components are exposed to the working environment for a long time. Especially in casting and injection molding workshops, residual material falling off the mold (such as flash and granules) can easily intrude into the gaps of the sliding pairs, leading to increased sliding resistance and problems such as jamming and accelerated wear. This not only affects the smoothness and positioning accuracy of the trolley's opening and closing action, but also significantly shortens the service life of key moving parts, increasing maintenance costs and downtime.

[0027] As shown in Figure 1, Figure 2 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides an opening and closing mold trolley, which includes a base module and at least one support module. The base module includes a base assembly with a discharge groove 120 and a blocking member. The support module includes a pair of support components, each pair of support components being arranged opposite each other in a first direction. The support components are used to detachably connect one half of the mold, and all support modules are spaced apart in a second direction. In the first direction, the support components and the base assembly are movably connected to form a sliding pair. The blocking member is located above the sliding pair and is used to block the sliding pair. Each sliding pair is provided with a corresponding discharge groove 120 for collecting waste material.

[0028] In these embodiments, a mold-opening and closing trolley is provided for transporting and opening / closing large plastic injection molds. The mold-opening and closing trolley includes a base module and at least one support module.

[0029] The base module includes a base assembly, which is welded from high-strength steel plates and has an overall rectangular frame structure, providing good load-bearing capacity and structural stability. Discharge grooves 120 are formed along the length of both sides of the upper surface of the base assembly. These grooves are U-shaped and extend through the height of the base assembly for material discharge.

[0030] The support module includes a pair of support components, each pair of support components being arranged opposite each other in a first direction (i.e., the left-right direction, X direction). Each support component is detachably connected to one half of the mold (such as a moving mold or a fixed mold) by bolts. All support modules are spaced apart in a second direction (i.e., the front-back direction, Y direction), and their number and position can be flexibly adjusted according to the size of different molds. In other words, it is possible to perform a clamping action on multiple molds.

[0031] In the first direction, each support component is movably connected to a guide rail on the base component via a slider, forming a sliding pair. This sliding pair allows the support component to slide relative to the base component in the X direction, thereby realizing the opening and closing action of the mold.

[0032] Crucially, a shield is provided above the sliding joint. The shield is fixed to the bottom extension of the support assembly and is a downwardly bent L-shaped plate structure that covers the gap area between the guide rail and the slider. As the support assembly slides, the shield moves synchronously with it, always remaining directly above the sliding joint, effectively preventing residual material (such as plastic flash or granules) from falling directly into the sliding joint.

[0033] In addition, a discharge trough 120 is provided directly below each moving part. When a small amount of impurities breaks through the shield or enters from the side and falls off, they can fall directly into the discharge trough 120 below, avoiding accumulation around the moving parts.

[0034] Clearly, the above structure effectively protects the sliding pair, significantly reduces the contamination of the sliding pair by external impurities, ensures the smoothness of opening and closing actions, reduces the risk of wear, and extends the service life of the equipment.

[0035] For example, the shielding member includes a main body and a shielding wing extending downward from one side of the main body. The main body is horizontally disposed and covers the top opening of the movable pair. The shielding wing extends along the length of the guide rail, close to but not in contact with the outer wall of the guide rail, forming a lateral protective barrier.

[0036] The end of the shielding wing bends inward to form a guide edge, which maintains a small gap (e.g., 0.5 to 1 mm) with the side of the guide rail. This effectively blocks lateral splashes of residual material without hindering the normal sliding of the support assembly.

[0037] Furthermore, the shielding component is made of stainless steel sheet by stamping, which has good wear resistance and corrosion resistance. It is fixed to the mounting base at the bottom of the support assembly with screws, making it easy to disassemble and replace.

[0038] In some embodiments, the support assembly includes an adapter 300 and a support member 200, the adapter 300 being detachably connected to one of the mold halves. The support member 200 and the adapter 300 are detachably connected, and the support member 200 is movably connected to the base.

[0039] In these embodiments, the internal structure of the support components is further refined, and a modular design is adopted to improve assembly flexibility and maintenance convenience.

[0040] The adapter 300 is a connection module adapted to different mold interfaces. One end of it is equipped with a connection structure (such as a locating pin, stud, or flange) that matches the positioning hole or threaded hole on the mold half, allowing for detachable connection via bolts. For different mold models, the corresponding adapter 300 can be replaced, enabling quick mold changes.

[0041] The support member 200 serves as the main load-bearing component, and its top is provided with a connection interface (such as a threaded hole or slot) that mates with the adapter 300, enabling a detachable connection via screws or quick-release pins. The bottom of the support member 200 integrates a slider structure, which forms a movable connection with the guide rail on the base assembly, constituting the aforementioned sliding pair.

[0042] For example, the adapter 300 and the support 200 are connected by a standardized interface, which facilitates serialized production and on-site replacement. The appropriate adapter 300 can be selected according to the type of mold.

[0043] In this embodiment, the adapter 300 has an upward-facing retaining opening, and the mold half has a retaining portion. The retaining portion and the retaining opening engage to achieve a snap-fit ​​detachable connection between the mold half and the adapter 300. Of course, in other embodiments, the adapter 300 may also be implemented using structures such as grippers or chucks, which are not specifically limited here.

[0044] This application makes the support component highly versatile and adaptable: when the mold needs to be changed, only the corresponding adapter 300 needs to be replaced, without replacing the entire support component; at the same time, if a component is damaged during maintenance, it can be disassembled and replaced separately, reducing maintenance costs.

[0045] In some embodiments, the support member 200 includes a support portion and a rolling portion 210, which are connected and the rolling portion 210 rolls into contact with the base assembly.

[0046] In these embodiments, the structure of the support member 200 is optimized by upgrading the original sliding pair to a rolling pair to further reduce motion resistance, improve running smoothness, and reduce wear.

[0047] The support part is the main load-bearing structure, and its top is provided with a connection interface for detachable connection with the adapter 300 by bolts; its interior is hollow or has reinforcing ribs to reduce the overall weight while ensuring strength.

[0048] The rolling part 210 is fixed to the bottom of the support part and includes a wheel frame and multiple rollers (e.g., a double-row four-wheel structure) mounted on the wheel frame. The rollers are made of high-strength engineering plastics (such as polyurethane) or bearing steel, and have a smooth and wear-resistant outer surface.

[0049] The base assembly is equipped with a guide rail that matches the roller. This guide rail has a convex or V-shaped track structure. The roller rolls along the guide rail, realizing a movable connection between the support member 200 and the base assembly, forming a rolling pair (replacing the original sliding pair).

[0050] For example, the roller has a built-in deep groove ball bearing to ensure smooth rotation. The wheel frame is bolted to the support for easy disassembly and maintenance.

[0051] The shield is still located at the bottom of the support or above the wheel frame, covering the meshing area between the roller and the guide rail to prevent residual material from falling into the roller gap or the guide rail surface, thus avoiding jamming or abnormal wear.

[0052] This rolling structure significantly reduces frictional resistance during mold opening and closing, making operation easier, especially suitable for frequent opening and closing operations of heavy molds. At the same time, compared to sliding friction, rolling contact facilitates assembly and disassembly, and requires lower assembly precision.

[0053] In some embodiments, the base assembly includes a support member 100 having a groove extending along the first direction, a rolling part 210 located in the groove, and the rolling part 210 and the groove in a roller-assisted engagement; wherein, a blocking member is disposed on the support member 100, the rolling part 210 is located between the blocking member and the groove, and the discharge chute 120 is disposed on the support member 100.

[0054] In these embodiments, the support member 100 is a metal structural member that is integrally cast or welded, and has high strength and good rigidity.

[0055] The support member 100 has a groove along the first direction (X direction). The groove is a longitudinally extending U-shaped or rectangular through groove that extends through the height direction of the support member 100. The two sides of the bottom of the groove form guide surfaces for rolling cooperation with the rollers in the rolling part 210.

[0056] The rolling part 210 (including the wheel frame and rollers) is entirely located inside the slide groove. The rollers roll on the guide surface of the slide groove, enabling the support member 200 to move smoothly along the first direction. The sidewalls of the slide groove provide lateral restraint for the rollers, preventing the support assembly from shifting or derailing during operation.

[0057] Crucially, the shielding member is fixedly disposed in the top opening area of ​​the support member 100, specifically by means of screws, welding, or integral molding, etc., and is installed on the upper edge of the slide or the top surface of the support member 100. For example, the shielding member extends downward to form a protective cover, covering the top opening of the slide.

[0058] Therefore, the rolling part 210 is located between the blocking member and the chute: the upper part is closed by the blocking member to prevent the residual material (such as plastic particles or metal shavings) falling from the upper part from falling directly into the chute; The bottom is supported by the slide body. A small amount of impurities that penetrate the shield or enter from the side fall directly into the bottom of the slide when they fall off during the movement of the rolling part 210.

[0059] Furthermore, the discharge trough 120 is disposed on the support member 100 and at least partially overlaps with or shares a bottom area with the chute in the vertical direction. Preferably, the bottom of the chute constitutes the main body of the discharge trough 120. The bottom surface of the discharge trough 120 is set as an inclined surface and is provided with a discharge port to facilitate the automatic sliding out of accumulated material.

[0060] In some embodiments, the discharge chute 120 is located in the chute and extends through the bottom of the chute.

[0061] In these embodiments, the discharge chute 120 is directly integrated into the chute, forming a more compact and efficient discharge mechanism, further enhancing pollution prevention capabilities and ease of maintenance.

[0062] The discharge chute 120 is no longer located just below the chute or connected to its bottom, but extends directly through the bottom of the chute.

[0063] The discharge chute 120 has a long and narrow opening, which is arranged along the length of the chute. Its width ensures that the overall strength of the chute is not significantly affected, while being large enough to ensure that residual material can pass through smoothly.

[0064] To prevent excessively large particles or foreign objects from directly entering the discharge chute 120 and causing blockage, a coarse filter screen can be installed above the discharge chute 120. This filter screen is fixed to the side walls of the chute, allowing fine dust and debris to pass through, but blocking larger lumps.

[0065] In addition, the shielding component still covers the top opening of the chute, effectively preventing most of the residual material falling from above from directly entering the chute. Even if a small amount of impurities intrudes from the side, they will gradually fall off with the movement of the rolling part 210 and fall into the discharge chute 120, thus being discharged in time.

[0066] In some embodiments, the base assembly further includes a limiting member, one end of the groove is configured as an open end, the limiting member and the carrier 100 are detachably connected, the limiting member is at least partially located at the open end, and is used to limit the rolling part 210 so that it is located within the groove.

[0067] In these embodiments, a detachable limiting member is added to prevent the rolling part 210 from accidentally dislodging from the groove during movement, while also taking into account the convenience of assembly and maintenance.

[0068] One end of the slide is set as an open end. This open end allows the rolling part 210 to be pulled out of the slide as a whole during initial installation or maintenance disassembly, facilitating quick assembly and replacement.

[0069] To prevent the support assembly from sliding excessively along the first direction (X direction) during normal operation, causing the roller to disengage from the chute, this embodiment provides a limiting member at the opening end.

[0070] The limiting component is a stop or baffle, which is detachably connected to the carrier 100 by screws. A part of the limiting component extends into the open end of the slide groove to form a physical block. Its inner end face is flush with or slightly lower than the guide rail surface of the slide groove to ensure that it does not interfere with the normal sliding of the rolling part 210.

[0071] When the rolling part 210 moves to the limit position of the slide groove, its wheel frame or roller shaft end contacts the limiting member and is effectively blocked to prevent it from coming off.

[0072] Furthermore, since the limiting component is detachable, when deep cleaning, maintenance, or replacement of the rolling part 210 or the inside of the slide is required, the limiting component can be removed first, and then the entire support assembly can be pulled out along the opening end, which greatly improves maintenance efficiency.

[0073] In some embodiments, the support assembly further includes a locking member connected to the support member 200, the locking member being capable of locking the position of the support member 200 in the first direction.

[0074] In these embodiments, this embodiment further adds a locking component to the support assembly to reliably lock the position of the support component 200 after the mold is opened and closed, preventing it from sliding unexpectedly due to vibration, external impact or other reasons during transportation or operation, thereby improving the safety and positioning accuracy of the equipment operation.

[0075] The locking element is fixedly connected to the side wall or bottom extension of the support 200, specifically located on the side of the support 200 near the carrier 100.

[0076] For example, the locking element includes an operating handle, a drive screw, and a clamping head. The drive screw passes through a threaded hole in the support member 200 or the wheel frame, with one end connected to the operating handle and the other end connected to the clamping head. When the handle is rotated, the screw drives the clamping head to move axially, thereby clamping or releasing the support member 100 or the sidewall of the slide.

[0077] Of course, in other embodiments, the locking member can also be other structures, as long as it can lock the position of the support member 200 in the first direction.

[0078] In some embodiments, the locking member includes a insertion slot 500 and an insertion portion 400, the insertion portion 400 passing through the insertion slot 500, the insertion slot 500 being disposed on the support member 200, the carrier member 100 having a plurality of insertion holes 130, the plurality of insertion holes 130 being spaced apart along a first direction, the plurality of insertion holes 130 being located on the movement path of the insertion portion 400, and the insertion portion 400 being selectively inserted into one of the insertion holes 130.

[0079] In these embodiments, the structure of the locking member is specifically configured, and a segmented pin locking mechanism is adopted to achieve rapid and reliable locking of the support member 200 in multiple preset positions, which is particularly suitable for working conditions that require precise positioning or repeated positioning.

[0080] The insertion slot 500 is a guide sleeve or U-shaped groove structure fixedly installed on the side wall or bottom of the support member 200, and its extension direction is perpendicular to the first direction (X direction), that is, arranged along the Z direction (vertical direction) or the Y direction (lateral direction).

[0081] The insertion part 400 is a sliding pin or plug that passes through the insertion groove 500 and can move along the axial direction of the insertion groove 500 under the action of external force to realize the insertion or removal action.

[0082] The upper end of the plug-in portion 400 is provided with an operating handle or pull ring for easy manual operation. For example, the middle part of the plug-in portion 400 is provided with an elastic reset element (such as a spring), which can automatically pop out when released to prevent accidental locking.

[0083] The support member 100 has a plurality of insertion holes 130 along the first direction (X direction). These insertion holes 130 are arranged in a straight line with equal spacing (for example, one every 100 mm), forming a plurality of preset positioning positions. The diameter of the insertion holes 130 matches the outer diameter of the insertion part 400 to ensure sufficient shear strength after insertion.

[0084] When the support member 200 slides along the groove to a target position, the operator pushes the plug part 400 downward (or laterally) so that it passes through the plug groove part 500 and can be selectively inserted into one of the plug holes 130, thereby locking the support member 200 in that position.

[0085] By selecting different insertion holes 130, the support components can be quickly switched and locked between multiple fixed positions to meet the precise positioning requirements under different mold widths or process requirements.

[0086] Furthermore, it should be noted that the mold dimensions vary depending on the product type. In practical use, the distance between the support members 200 can be changed by inserting the connector 400 into the connector holes 130 at different positions, thereby adapting to molds of corresponding sizes. For example, if the distance between a pair of support members 200 is too small or too large after changing to a different mold, the position of the connector 400 can be changed to adjust the distance between the pair of support members 200, adapting to different molds and thus improving the versatility of this application.

[0087] For example, the entrance of the plug hole 130 is chamfered to facilitate the alignment and insertion of the plug part 400. The end of the plug part 400 is also rounded to improve the smoothness of operation.

[0088] In some embodiments, the top of the carrier 100 has a bearing end face, and the support 200 has a sliding end face. The bearing end face and the sliding end face are respectively arranged parallel to the first direction, and the sliding end face and the bearing end face are slidably engaged.

[0089] In these embodiments, the contact relationship between the support member 200 and the load-bearing member 100 is further clarified, and an end face sliding fit structure is introduced to enhance the stability, load-bearing capacity and anti-overturning performance of the support assembly during movement.

[0090] The top of the support member 100 is provided with a support end face. The support end face is a precision-machined (such as ground or milled) plane that extends along the first direction and is arranged parallel to the first direction to ensure surface flatness and levelness.

[0091] The bottom of the support member 200 is provided with a sliding end face, which is a planar structure that matches the bearing end face and is also arranged parallel to the first direction.

[0092] When the support member 200 is installed on the carrier member 100, its sliding end face forms a surface contact sliding fit with the carrier end face of the carrier member 100. During the sliding process of the support assembly along the first direction, the sliding end face always fits against the carrier end face, achieving smooth sliding.

[0093] The bearing end face directly bears the weight of the support member 200 and the mold above it. Through large-area contact, the load is distributed, stress concentration is avoided, and structural strength is improved. The surface contact structure effectively suppresses the vertical movement or torsion of the support member 200 during movement, ensuring smooth opening and closing. When the mold's center of gravity shifts or is subjected to external impact, the friction between the bearing end face and the sliding end face effectively resists lateral forces and overturning moments, preventing equipment instability.

[0094] In this embodiment, the rolling part 210 (such as a roller) still serves as the main guiding and friction-reducing element, while the cooperation between the sliding end face and the bearing end face mainly undertakes the vertical load and stabilization functions. The two work together to balance low friction and high rigidity.

[0095] Optionally, a wear-resistant material layer (such as a PTFE patch or bronze liner) can be applied to the sliding end face to reduce the coefficient of sliding friction, decrease wear, and extend service life. In addition, an elastic flange or elastic sealing strip (not shown) can be provided on the outer periphery of the bearing end face to prevent coolant, oil, or fine particles from directly intruding into the sliding contact surface, further improving environmental adaptability.

[0096] In some embodiments, the adapter 300 and the support 200 are rotatably connected, and the rotation axis of the adapter 300 is perpendicular to the bearing end face.

[0097] In these embodiments, this embodiment optimizes the connection between the adapter 300 and the support 200, upgrading it from a rigid connection to a rotatable connection, so that the adapter 300 can rotate relative to the support 200 within a certain angle range, thereby improving the adaptability and centering accuracy of mold installation.

[0098] The adapter 300 and the support 200 are rotatably connected. Specifically, a connecting seat is provided on the top of the support 200, on which a slewing bearing or pivot structure (such as a combination of a pin and a bearing) is mounted. The adapter 300 is rotatably connected to the connecting seat through this structure and locked by the pin.

[0099] The rotation axis of the adapter 300 extends vertically, that is, it is perpendicular to the bearing end face. Therefore, the adapter 300 can rotate around this axis in a limited angle in the horizontal plane (i.e., the XY plane).

[0100] When the mold half is placed on the support assembly, its positioning hole or mounting surface may be slightly misaligned from the ideal position due to manufacturing tolerances or lifting deviations. At this time, the adapter 300 can automatically adjust the angle by slight rotation, so that the connecting structure (such as bolts or positioning pins) can be smoothly aligned and installed, avoiding stress concentration or damage caused by forced assembly.

[0101] For example, a damping element (such as a friction plate or a hydraulic damper) can be provided in the rotating connection structure to keep the adapter 300 stable in the free state and to rotate only when an external force is applied, thus preventing accidental rotation during transportation or opening and closing.

[0102] In addition, to prevent excessive rotation from affecting safety, a mechanical stop can be installed on the connector to limit the maximum rotation angle of the adapter 300.

[0103] In some embodiments, the bottom of the support member 100 is formed with a plurality of support legs 110.

[0104] In these embodiments, multiple support legs 110 are added to achieve stable support, height adjustment, and ground adaptability for the entire machine. For example, the support legs 110 can be configured as lifting legs.

[0105] The bottom of the support member 100 is integrally formed or welded with multiple support legs 110. The support legs 110 are distributed along the length direction (first direction, X direction) and width direction (second direction, Y direction) of the support member 100. Preferably, one support leg 110 is provided at each of the four corners of the support member 100 to form a stable four-point support structure.

[0106] Multiple support legs 110 form the supporting foundation of the base module, which evenly transfers the load of the entire mold opening and closing trolley (including the weight of the mold) to the ground, avoiding local stress concentration.

[0107] It should be noted that the support leg 110 can be used to lift the load-bearing component 100, which facilitates the transfer of equipment such as forklifts, and enables the transfer and transportation between the mold opening area and the casting area.

[0108] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0109] 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.
