Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a quick-assembly and disassembly electrical cabinet for injection molding machines. Background Technology

[0002] Injection molding machines, also known as injection molding machines, are one of the most commonly used pieces of equipment in the plastics processing industry. They are mainly used for molding thermoplastic and thermosetting plastics.

[0003] There are many actuators, position switches, and sensors outside the injection molding machine's power distribution cabinet. Currently, these signals are directly connected to the control components inside the cabinet. The cables for these actuators, position switches, and sensors are separately introduced into the power distribution cabinet and interconnected with control units and other electrical components via wiring. For overseas markets, due to container size limitations, pre-wiring of the power distribution cabinet and related components is typically completed domestically before the components are shipped to overseas factories for assembly by local workers. When dealing with external cables of the injection molding machine's power distribution cabinet, these cables must be individually removed from the electrical components inside the cabinet, transported overseas, and then assembled.

[0004] When injection molding machine power distribution cabinets are sold to overseas markets, the cables connecting the external parts of the power control cabinet need to be disconnected one by one in China. After being transported abroad, they are then reassembled by local workers. This process of disconnecting and reconnecting cables is cumbersome, labor-intensive, and prone to errors, resulting in low efficiency. Utility Model Content

[0005] To improve assembly efficiency, this utility model provides a quick assembly and disassembly electrical cabinet for injection molding machines.

[0006] The present invention provides a quick-assembly and disassembly electrical cabinet for an injection molding machine, which adopts the following technical solution: A quick-assembly and disassembly electrical cabinet for an injection molding machine includes a housing for placing electrical components, and a plurality of plug-in mechanisms are provided on the side wall of the housing; The connection mechanism includes a base and a plug. The base is used to connect electrical components inside the enclosure, and the plug is used to connect external cables and dock with the base. A through hole is provided on one side of the enclosure for the electrical components inside the enclosure to connect with the base.

[0007] By adopting the above technical solution, and by setting a plug-in mechanism including a base and a plug on the side wall of the enclosure, the modularization and quick plugging and unplugging of external cables of the power distribution cabinet are realized, which simplifies the wiring and disconnection process of cables during assembly, improves assembly efficiency, and at the same time, by fixing the base in the through hole, it is convenient for cables to pass through.

[0008] Optionally, the base is provided with a locking component, and the plug is provided with a protrusion. The locking component and the protrusion are used to lock the base and the plug tightly together.

[0009] By adopting the above technical solution, a locking component is set on the base and a protrusion is set on the plug. The locking component and the protrusion work together to lock the base and the plug tightly, which can effectively prevent the plug and the base from accidentally coming loose during use due to vibration, external force and other factors, thereby enhancing the stability and reliability of the connection between the base and the plug.

[0010] Optionally, the locking components are symmetrically arranged on the base, and each locking component includes a rotating part that is rotatably connected to the base and a engaging part that engages with the protrusion; the engaging part and the rotating part are arranged at an angle to form a locking groove for placing and engaging the protrusion, and when the base is connected and locked to the plug, the protrusion is engaged in the locking groove.

[0011] By adopting the above technical solution, the locking components are symmetrically arranged on the base, with each component including a rotating part for rotational connection and a engaging part for engaging with the protrusion, forming an angle to create a locking groove for engaging the protrusion. This symmetrical arrangement makes the force more even. When the base and plug are docked and locked, the protrusion engages in the locking groove, which can limit and fix the plug from multiple directions, further improving the locking strength. At the same time, the rotating part facilitates locking and unlocking operations, making the entire connection process more convenient, stable and reliable.

[0012] Optionally, a guide head for guiding is provided on the side of the engaging portion away from the rotating portion, and the side of the guide head away from the engaging portion is an arc surface.

[0013] By adopting the above technical solution, a guide head with an arc surface is provided on the engaging part. When the rotating part drives the guide head to rotate, the arc surface of the guide head contacts the outer surface of the protrusion, thereby reducing wear caused by hard collision and facilitating blind operation when the field of vision is limited.

[0014] Optionally, the guide head is provided with a contact plate at one end away from the engaging portion for contacting the protrusion, and the thickness of the contact plate is greater than the thickness of the guide head.

[0015] By adopting the above technical solution, a contact plate is added to the end of the guide head, which increases the effective contact area with the protrusion, making the locking force distribution more uniform. This not only improves the stability of locking and reduces shaking after connection, but also enhances the structural strength of this part.

[0016] Optionally, a bending portion is provided at the connection between the rotating part and the engaging part, the bending portion being used to bend the engaging part away from the contact plate.

[0017] By adopting the above technical solution, a bending part is set at the connection between the rotating part and the engaging part, the position of the contact plate is adjusted, the distance between the contact plate and the plug is increased, the probability of friction is reduced, the stability of the component is improved, and the service life is extended.

[0018] Optionally, the rotating parts on both sides of the base are symmetrically arranged, and a connecting member is provided between the two symmetrically arranged rotating parts for connection. A lever is provided on the side of the connecting member away from the rotating part, and the lever is used to push and pull the connecting member.

[0019] By adopting the above technical solution, the rotating part is first set to a symmetrical form, and then the symmetrical rotating parts are connected by a connector. A paddle is set at the connector. When the paddle is pushed manually to move, the rotating parts on both sides can be rotated at the same time, making the operation more convenient and labor-saving.

[0020] Optionally, the locking assembly further includes an elastic element for driving the rotating part to rotate in the direction of the protrusion.

[0021] By adopting the above technical solution, by adding an elastic element to drive the rotating part to rotate in the direction of the protrusion, after the plug is inserted into place, the elastic force can automatically pull the rotating part to the locking position, and continuously apply a holding force to resist vibration interference in the locked state to prevent accidental unlocking.

[0022] Optionally, the plug may have a gripping protrusion on the side away from the base to assist in plugging and unplugging operations.

[0023] By adopting the above technical solution, a gripping protrusion is provided on one side of the plug, which makes it easier for the operator to insert and remove the plug. It provides the operator with a clear point of force and a non-slip surface, making it easier to apply force with the fingers. This makes it more convenient, comfortable and safe when inserting or removing the plug or unlocking the plug, which requires greater force.

[0024] Optionally, the housing is provided with a removable sealing plate, which is used to close the through hole when the connector mechanism is not installed.

[0025] By adopting the above technical solution, a detachable sealing plate is set to close the through holes where no connector mechanism is installed, which enhances the configuration flexibility and protection of the distribution cabinet. The position of the connector can be selected according to actual needs, the integrity of the side wall of the cabinet is maintained, and foreign objects such as dust and moisture are effectively prevented from entering the cabinet through the empty holes.

[0026] In summary, this utility model has at least one of the following beneficial technical effects: 1. By setting a connection mechanism including a base and a plug on the side wall of the enclosure, and using the locking component on the base to cooperate with the protrusion on the plug to achieve a tight connection, the modularization and quick plugging and unplugging of the external cable connection of the power distribution cabinet are realized, which simplifies the wiring and disconnection process of the cable during assembly, improves the assembly efficiency, and at the same time, by fixing the base in the through hole, the cable can pass through easily. 2. The locking assembly, consisting of a rotating part and a locking part, is used to lock with the protrusion. The circumferential locking is completed by rotating the rotating part, and the protrusion is snapped into the locking groove. The locking is completed by a simple rotation action, without the need for additional complicated wiring operations, which simplifies assembly while ensuring the stability of the connection. 3. By adding an elastic element to drive the rotating part to rotate in the direction of the protruding post, after the plug is inserted into place, the elastic force can automatically pull the rotating part to the locking position, and continuously apply a holding force to resist vibration interference in the locked state to prevent accidental unlocking.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1 and Figure 2 This utility model discloses a quick-assembly and disassembly electrical cabinet for an injection molding machine, which includes a housing 1 for storing electrical components. In this embodiment, the housing 1 is equipped with three side-by-side doors, which can be opened as needed, either one, two, or all three doors, thereby saving space.

[0031] Reference Figure 2 and Figure 3 Several connector mechanisms 2 are installed on the side walls at both ends of the enclosure 1 along its length, and these connector mechanisms 2 are evenly spaced along the height of the enclosure 1. Each connector mechanism 2 includes a base 21 and a plug 22. The base 21 is used to connect and integrate the internal cables of various electrical components within the enclosure 1. The plug 22 is used to connect external cables and mate with the base 21. The enclosure 1 has through holes 11 for the internal cables to pass through. The edge of the base 21 is larger than the size of the through holes 11. The specific size of the through holes 11 is determined according to the actual situation, allowing the base 21 to be fixed to the enclosure 1 with bolts. The through holes 11 provide a centralized and orderly channel for the internal cables of various electrical components within the enclosure 1, facilitating the connection of internal cables to the base 21 and preventing cables from being randomly distributed inside and outside the enclosure 1.

[0032] Reference Figure 2 and Figure 3 A removable sealing plate 12 is installed on the housing 1 to cover the through hole 11. The removable sealing plate 12 is larger than the through hole 11 to completely cover it, and space is reserved for the mounting base 21 of adjacent through holes 11. The specific size is determined according to the actual situation. The removable sealing plate 12 is fixedly connected to the housing 1 by screws. When the connector mechanism 2 is not installed, the removable sealing plate 12 seals the through hole 11 to prevent the entry of external dust. If there are sealing requirements such as dustproofing and moisture-proofing, a sealing strip can be set on the edge of the removable sealing plate 12.

[0033] Reference Figure 3 and Figure 4 Locking components 211 are installed on both circumferential sidewalls of the base 21. Each locking component 211 includes a rotating part 2111 and a engaging part 2113. A rotating shaft is rotatably mounted on the circumferential sidewall of the base 21. The rotating part 2111 is sleeved and rotatably mounted on the rotating shaft. The engaging part 2113 is integrally located at the end of the rotating part 2111 away from the rotating shaft, forming an angle between the engaging part 2113 and the rotating part 2111. A locking groove 2114 is formed between the rotating part 2111 and the engaging part 2113. A protrusion 221 is integrally provided on the plug 22 for mutual contact and positioning with the engaging part 2113. When the plug 22 is mated with and locked in place with the base 21, the protrusion 221 engages in the locking groove 2114, thereby preventing the plug 22 from detaching from the base 21.

[0034] Reference Figure 3An elastic element 2112 is mounted on the rotating part 2111 and the base 21. The elastic element 2112 drives the rotating part 2111 to rotate towards the protrusion 221, thereby providing a locking force. The elastic element 2112 is V-shaped, and a spring shaft 21111 for fixing the elastic element 2112 is integrally provided on the rotating part 2111. One end of the elastic element 2112 is sleeved on the spring shaft 21111, and the other end of the elastic element 2112 is sleeved on the rotating shaft.

[0035] Reference Figure 3 and Figure 4 The engaging portion 2113 has a guide head 2115 on the side away from the rotating portion 2111 for guiding. The guide head 2115 is semi-circular, and the side of the guide head 2115 away from the engaging portion 2113 is arc-shaped. The diameter of the guide head 2115 is larger than the width of the engaging portion 2113. When the plug 22 is inserted into the base 21, the protrusion 221 abuts against the guide head 2115 on the side away from the engaging portion 2113 and slides into the locking groove 2114, thereby reducing the jamming and wear caused by the protrusion 221 abutting against the engaging portion 2113, and improving the smoothness of insertion and removal and the operating feel.

[0036] Reference Figure 3 and Figure 4 The end of the guide head 2115 away from the engaging part 2113 is integrally provided with a contact plate 2116 for contacting the protrusion 221. The thickness of the contact plate 2116 is greater than the thickness of the guide head 2115, which increases the contact area to reduce the surface compressive stress under repeated friction conditions, thereby reducing wear and extending service life.

[0037] Reference Figure 3 and Figure 4 A bending portion 2117 is integrally provided at the connection between the rotating part 2111 and the engaging part 2113. The bending portion 2117 is used to bend the engaging part 2113 away from the rotating part 2111. By adjusting the position of the contact plate 2116, the distance between the contact plate 2116 and the plug 22 is increased, which effectively reduces the probability of contact friction between the two, further improves the structural stability, and extends the service life of the relevant components.

[0038] Reference Figure 3 and Figure 4 To further improve the locking capability between the plug 22 and the base 21, the locking components 211 on both sides of the base 21 are symmetrically arranged about the base 21, and two locking components 211 are provided on the side walls at both ends of the base 21 along the height direction. The locking components 211 on the same side wall of the base 21 are symmetrically arranged about the center line of the short side of the base 21, and the locking components 211 on the same side wall of the base 21 rotate toward the base 21 to lock, thereby facilitating the locking of the plug 22 and the base 21.

[0039] Reference Figure 3 and Figure 4 To facilitate the locking assembly 211 in locking the plug 22 to the base 21, the length of the rotating part 2111 is designed to be greater than the distance between the pivot and the side wall of the base 21. A connecting member 2118 is integrally provided between the rotating parts 2111 in the same rotation locking direction, linking the rotating parts 2111 on both sides for simultaneous rotation. A lever 2119 is provided on the side of the connecting member 2118 away from the base 21, used for pushing and pulling the connecting member 2118. When the plug 22 is inserted into the base 21, the protrusion 221 on it pushes the elastic member 2112 away. Under the action of the elastic member 2112, the locking groove 2114 eventually abuts against the side of the protrusion 221, achieving a locking and fixing effect.

[0040] Reference Figure 3 The end of the plug 22 furthest from the base 21 is integrally provided with a gripping protrusion 222 for assisting insertion and removal operations. The gripping protrusion 222 has an arc-shaped structure protruding from the end face, thereby facilitating the application of force by fingers. The number and position of the gripping protrusions 222 can be adjusted according to actual conditions. In this embodiment, two gripping protrusions 222 are provided on each of the two end sidewalls of the plug 22 along the height direction. One of the gripping protrusions 222 on the same sidewall of the plug 22 faces the end of the plug 22 furthest from the base 21, and the other gripping protrusion 222 faces the adjacent end of the plug 22 furthest from the base 21.

[0041] Reference Figure 1 and Figure 2 The housing 1 is bolted with a protective cover 3 for covering the connector mechanism 2, which prevents dust from entering. In this embodiment, the side wall of the protective cover 3 adjacent to the side of the housing 1 where the door is located is open, so as to facilitate direct contact with the wall and reduce the use of raw materials. The protective cover 3 is also integrally provided with a plate for bolting to the wall.

[0042] The implementation principle of the quick assembly and disassembly cabinet for an injection molding machine according to this utility model embodiment is as follows: When the plug 22 moves towards the base 21, the protrusion 221 on the plug 22 abuts against the guide head 2115 and pushes the guide head 2115 to move away from the center of the base 21. The guide head 2115 drives the locking part 2113 to move, and the locking part 2113 drives the rotating part 2111 to move. The rotating part 2111 overcomes the elastic force of the elastic element 2112 and rotates along the rotating shaft towards the center of the base 21, so that the protrusion 221 and the guide head 2115 are always in contact until the protrusion 221 falls into the locking groove 2114. At this time, the elastic force of the elastic element 2112 pushes the rotating shaft to rotate towards the center of the base 21, so that the locking part 2113 limits the protrusion 221, thereby locking the plug 22 onto the base 21.

[0043] When the plug 22 is removed from the base 21, the lever 2119 is manually pushed towards the housing 1, causing the lever 2119 to rotate with the connector 2118. The connector 2118 synchronously drives two symmetrically arranged rotating parts 2111 to overcome the elastic force of the elastic element 2112 and rotate along the shaft away from the center of the base 21. The rotating parts 2111 move the engaging part 2113 until the protrusion 221 moves out of the locking groove 2114. At this point, the plug 22 is gripped by the gripping protrusion 222 and pulled off the base 21. This structural design makes plug connection and disconnection simple and quick, improving the assembly efficiency of the equipment.

[0044] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
