Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a quick-release locking device for a mold water collector. Background Technology

[0002] As a core component of the mold cooling system, the mold water collector integrates the pipes of various cooling units of the mold onto a single module to improve mold changing efficiency. For example, CN116100007A discloses a quick-connect water collector, including a mold-end water collector and a press-end water collector, which are directly opposite each other. The mold-end water collector has multiple connectors arranged in a regular pattern, and the press-end water collector has connection holes corresponding to each connector. A first quick-connect fitting is provided at the end of each connection hole away from the mold-end water collector. Each connector includes a first quick-connect fitting. The system comprises two quick-connect fittings, a through-hole plug, a connecting water pipe, and a sealing ring. The second quick-connect fitting is axially movable to the connecting water pipe. The through-hole plug is fitted onto the outside of the second quick-connect fitting. A spring is installed between the through-hole plug and the connecting water pipe. The sealing ring is fitted onto the end of the connecting water pipe and seals against the connecting hole. A mold-end water collector and a press-end water collector are quickly connected via bolt-type quick clamps. The mold-end water collector has bolt-type clamp hooks on a set of opposite sides, and the press-end water collector has bolt-type clamps corresponding to the bolt-type clamp hooks. When using the above water collectors, first press the press-end water collector onto the mold-end water collector, aligning each connector with each connecting hole. Then, tighten the connection by using the bolt-type clamps on both sides of the press to secure the hooks on both sides of the mold-end water collector.

[0003] However, due to the large number of connectors and the presence of spring components within each connector, the insertion resistance is high when mating with the connection holes. Consequently, operators need to use sufficient tension to tighten the bolt clamps, or equip them with bolt clamps with high torque, which undoubtedly increases the workload of the operators. At the same time, when separating the water collector, the cooling water in the mold will overflow under the action of residual pressure, and the cooling water remaining in the mold will also corrode the mold's water channels. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a quick-release locking device for a mold water collector.

[0005] The technical solution of this utility model is as follows: a quick-release locking device for a mold water collector, comprising a flow divider plate fixed to one side of the mold and a flow collector plate directly opposite the flow divider plate. The flow collector plate is equipped with an inlet female connector connected to the inlet main pipe and an outlet female connector connected to the outlet main pipe. The flow divider plate is equipped with corresponding inlet sub-connectors and outlet sub-connectors. The flow divider plate has several sets of inlet distribution channels connected to the inlet sub-connectors and outlet distribution channels connected to the outlet sub-connectors. A pull stud is fixed to the side of the manifold near the collector plate. A locking device is provided on the collector plate to cooperate with the pull stud. The locking device includes a locking housing fixed through the collector plate and a locking shaft coaxially disposed within the locking housing. The locking shaft has a locked state and an unlocked state. In the locked state, one end of the locking shaft is connected to the pull stud via a self-locking structure, which restricts the movement of the pull stud. In the unlocked state, external force drives the other end of the locking shaft away from the pull stud, thereby releasing the self-locking structure from restricting the pull stud. In this locking device, the manifold and the distributor plate are connected only through the same number of female and male connectors as the inlet and outlet manifolds. The insertion resistance is significantly reduced compared to existing technologies. When locking the manifold and distributor plate, there is no need to operate the locking device; the self-locking connection between the locking device and the pull stud is achieved simply by pressing the manifold. The operation is more convenient than existing technologies, effectively reducing the operator's workload.

[0006] The inlet female connector, the outlet female connector, the inlet sub-connector, and the outlet sub-connector are all valve-less connectors. The inlet female connector and the inlet sub-connector, and the outlet female connector and the outlet sub-connector are sealed together by sealing rings. Using valve-less connectors can minimize the insertion resistance between connectors.

[0007] The self-locking structure includes a limiting ring, a spring, and a first steel ball. The limiting ring is fixed inside the locking housing. The locking shaft is a T-shaped shaft. The smaller end of the T-shaped shaft passes through the limiting ring in the direction away from the pull pin. The spring is sleeved on the outside of the T-shaped shaft, and both ends of the spring abut against the limiting ring and the larger end of the T-shaped shaft, respectively. The larger end of the T-shaped shaft has an outer conical portion that tapers in size towards the pull pin. A slot for inserting the pull pin is provided on the outer conical portion. The inner wall of the slot has a plurality of radially penetrating steel ball limiting holes arranged in a circular array. The first steel ball is movably disposed in the steel ball limiting holes. The inner side of the locking housing near the pull pin has an inner conical portion that cooperates with the outer conical portion. The outer side of the pull pin has a wedge-shaped curved surface structure that forms a locking fit with the first steel ball.

[0008] A pressing element is provided on the inner side of the locking housing at the end away from the pull rivet. The pressing element is connected to the locking shaft via an unlocking mechanism to drive the locking shaft to move away from the pull rivet. By adding the pressing element, the convenience of unlocking the manifold and distributor plate is improved.

[0009] The unlocking mechanism includes several second steel balls. The pressing member has a sliding chamber for axial movement of the small end of the T-shaped shaft. The opening side of the sliding chamber has an inner conical surface that gradually decreases in size away from the pull stud. The surface of the T-shaped shaft located outside the pressing member has a concave curved surface structure. Each of the second steel balls is arranged in a circumferential array between the inner conical surface and the limiting ring. Under the inward pushing action of the inner conical surface, the second steel balls roll and cooperate with the concave curved surface structure to drive the locking shaft to move away from the pull stud.

[0010] A retaining ring is embedded on the outer side of the small end of the T-shaped shaft, and a stepped portion is provided on the inner side of the sliding cavity. The retaining ring cooperates with the stepped portion to prevent the pressing element from disengaging from the T-shaped shaft.

[0011] The manifold has two gas channels connected to the inlet and outlet female connectors, respectively. One gas channel is connected to a gas source via an inlet connector, and the other gas channel is connected to the outside via a blow-out connector. By adding gas channels to the manifold, before the water separator, gas is used to blow out the liquid from the water channels inside the mold and the inlet and outlet channels of the water separator, thereby preventing overflow and corrosion of the water channels.

[0012] A pair of handles are fixed on the end face of the collector plate away from the distributor plate.

[0013] The number of pull studs is several and is evenly distributed on the surface of the diverter plate. The number of locking devices is the same as the number of pull studs and is evenly distributed on the collector plate.

[0014] The beneficial effects of this utility model are as follows: by setting only the same number of male and female connectors as the inlet and outlet main pipes at the docking position of the manifold and the distributor plate to connect the liquid channels between the manifold and the distributor plate, the insertion resistance is significantly reduced compared with the prior art. At the same time, when locking the manifold and the distributor plate, there is no need to operate the locking device. The self-locking connection between the locking device and the pull pin can be achieved simply by pressing the manifold. The operation is more convenient than the prior art, thereby effectively reducing the operating intensity of the operator. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative effort should all fall within the protection scope of this utility model.

[0024] like Figure 1-Figure 3As shown, this utility model provides a quick-connect locking device for a mold water collector, including a diversion plate 1 fixed to one side of the mold and a collection plate 2 directly connected to the diversion plate 1. Specifically, in this embodiment, the diversion plate 1 is fixed to the pipe integration area of ​​the mold by mounting bolts 9. The collection plate 2 is equipped with an inlet female connector 201 connected to the inlet main pipe and an outlet female connector 202 connected to the outlet main pipe. The diversion plate 1 is equipped with corresponding inlet sub-connectors 101 and outlet sub-connectors 102. The diversion plate 1 has several sets of inlet branch channels 103 connected to the inlet sub-connectors 101 and outlet branch channels 104 connected to the outlet sub-connectors 102. By setting only the same number of female connectors as the inlet and outlet main pipes at the docking position of the collection plate 2 and the diversion plate 1, and by setting the inlet branch channels 103 and outlet branch channels 104 matching the number of water channels in the mold within the diversion plate 1, the water is diverted and connected, thereby... To effectively reduce the insertion resistance when the collector plate 2 and the distributor plate 1 are connected, a pull stud 3 is fixed on the side of the distributor plate 1 near the collector plate 2. The collector plate 2 is provided with a locking device 4 that cooperates with the pull stud 3. The locking device 4 includes a locking housing 401 that passes through and is fixed on the collector plate 2, and a locking shaft 402 that is coaxially arranged in the locking housing 401. The locking shaft 402 has a locked state and an unlocked state. In the locked state, one end of the locking shaft 402 is connected to the pull stud 3 through a self-locking structure so that the self-locking structure restricts the movement of the pull stud 3. In the unlocked state, an external force drives the other end of the locking shaft 402 to move away from the pull stud 3 so that the self-locking structure releases the restriction on the pull stud 3. By designing the above-mentioned locking device 4, when locking the collector plate 2 and the distributor plate 1, only the collector plate 2 needs to be pressed to achieve the self-locking connection between the locking device 4 and the pull stud 3. Compared with the existing technology, the operation is more convenient, thereby effectively reducing the operating intensity of the operator.

[0025] Further preferably, to minimize the insertion resistance between the connectors, the inlet female connector 201, the outlet female connector 202, the inlet sub-connector 101, and the outlet sub-connector 102 are all valve-less connectors. The inlet female connector 201 and the inlet sub-connector 101, and the outlet female connector 202 and the outlet sub-connector are sealed together by a sealing ring 5. Figure 2 As shown, the sealing ring 5 is embedded in the inlet female connector 201 and the outlet female connector 202.

[0026] Further preferably, in order to facilitate the operation of the collector plate 2, a pair of handles 7 are fixed on the end face of the collector plate 2 away from the diverter plate 1.

[0027] To facilitate the installation of the rivet 3, a threaded groove is provided at the end of the rivet 3 that is connected to the diverter plate 1. An installation groove for installing the rivet 3 is provided on the diverter plate 1. The fixing bolt 8 passes through the diverter plate 1 from the back side and is connected to the threaded groove of the rivet 3.

[0028] like Figure 4 As shown, the self-locking structure includes a limiting ring 404, a spring 403, and a first steel ball 405. The limiting ring 404 is fixed inside the locking housing 401. The locking shaft 402 is a T-shaped shaft. The smaller end of the T-shaped shaft passes through the limiting ring 404 in a direction away from the pull pin 3. The spring 403 is sleeved on the outside of the T-shaped shaft, and both ends of the spring 403 abut against the limiting ring 404 and the larger end of the T-shaped shaft, respectively. The larger end of the T-shaped shaft has a direction close to the pull pin 3. The outer conical portion of the nail 3 gradually decreases in size. A slot 4021 for inserting the nail 3 is provided on the outer conical portion. A plurality of radially penetrating steel ball limiting holes are arranged on the inner wall of the slot 4021. The first steel ball 405 is movably disposed in the steel ball limiting holes. The inner side of the locking housing 401 near the nail 3 has an inner conical portion that cooperates with the outer conical portion. The outer side of the nail 3 has a wedge-shaped curved surface 301 structure that forms a locking fit with the first steel ball 405. In the initial state, the outer cone of the locking shaft 402 is fitted into the inner cone of the locking housing 401. Since the diameter of the first steel ball 405 is larger than the distance between the inner wall of the slot 4021 and the outer wall of the outer cone, and the diameter of the first steel ball 405 is larger than the size of the through-hole of the steel ball, the first steel ball 405 partially protrudes from the slot 4021. During the docking operation, the pull pin 3, due to the obstruction of the first steel ball 405 within the slot 4021, pushes the locking shaft 402 outward, causing the outer cone and inner cone to separate, forming a gap for the first steel ball 405. The outward movement of the first steel ball 405 allows the pull pin 3 to fully enter the slot 4021. At this time, the compressed spring 403 drives the locking shaft 402 to reset, and the first steel ball 405 protrudes from the slot 4021 again. Figure 5 As shown, at this time, it cooperates with the wedge-shaped curved surface 301 on the surface of the rivet 3 to complete the self-locking operation of the collector plate 2 and the distributor plate 1.

[0029] To improve the convenience of unlocking operations, a pressing member 6 is provided on the inner side of the end of the locking housing 401 away from the pull tack 3. The pressing member 6 is connected to the locking shaft 402 via the unlocking mechanism to drive the locking shaft 402 to move away from the pull tack 3.

[0030] like Figure 4As shown, the unlocking mechanism includes a plurality of second steel balls 406. The pressing member 6 has a sliding chamber 601 for axial movement of the small end of the T-shaped shaft. The opening side of the sliding chamber 601 has an inner conical surface 602 that gradually decreases in size in the direction away from the pull stud 3. The surface of the T-shaped shaft located outside the pressing member 6 has a concave curved surface 4022 structure. Each of the second steel balls 406 is arranged in a circumferential array between the inner conical surface 602 and the limiting ring 404. Under the inward pushing action of the inner conical surface 602, the second steel balls 406 roll and cooperate with the concave curved surface 4022 structure to drive the locking shaft 402 to move in the direction away from the pull stud 3. When the operator unlocks the manifold 2, pressing the pressing member 6 causes the second steel ball 406 to move radially inward under the combined action of the inner conical surface 602 at the lower end of the pressing member 6 and the limiting plate. At this time, the second steel ball 406 rolls on the concave curved surface 4022 on the outer side of the locking shaft 402, causing the locking shaft 402 to move outward. The outer conical part and the inner conical part separate to form the movable gap of the first steel ball 405. Figure 6 As shown, under the self-elastic force of the sealing ring 5 of the female-female connector, the pull pin 3 disengages from the slot 4021 of the locking shaft 402, completing the unlocking operation of the collector plate 2 and the distributor plate 1. Compared with the tightening and locking and the external pulling and disengaging of the bolt-type clamp in the prior art, the push-type locking device 4 of this application significantly reduces the operating intensity of the operator.

[0031] To prevent the pressing member 6 from disengaging from the locking shaft 402, a retaining ring 407 is embedded on the outer side of the small-sized end of the T-shaped shaft. The sliding chamber 601 has a stepped portion on its inner side. The retaining ring 407 cooperates with the stepped portion to restrict the pressing member 6 from disengaging from the T-shaped shaft.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, the manifold 2 has two gas channels 203 that are respectively connected to the inlet female connector 201 and the outlet female connector 202. One gas channel 203 is connected to a gas source via an air inlet connector, and the other gas channel 203 is connected to the outside via a liquid blowing connector. By adding gas channels 203 to the manifold 2, before the water separator, gas is used to blow out the liquid from the water channels in the mold and the inlet and outlet channels 104 in the water separator, thereby avoiding overflow and corrosion of the water channels.

[0033] When the mold requires different media, such as hydraulic oil and cooling water, or when different temperatures of cooling media are used for adjustment, the number of inlet and outlet manifolds connected to the manifold 2 is two or more, and the size of the manifold 2 will increase accordingly. To ensure the stability of the locking between the manifold 2 and the distributor 1, several pull studs 3 are evenly distributed on the surface of the distributor 1. The number of locking devices 4 is the same as the number of pull studs 3, and they are evenly distributed on the manifold 2. Figure 7 As shown, there are four sets of locking devices 4 and pull pins 3, distributed at the four corners of the water collector. Alternatively, three sets can be used, arranged in a triangular distribution.

[0034] When implementing this technical solution, the diverter plate 1 is fixed to the outside of the mold with mounting bolts 9. Each water connector on the mold is connected to the corresponding liquid inlet channel 103 and liquid outlet channel 104 on the diverter plate 1. The outside of the manifold 2 is connected to the corresponding main liquid inlet pipe and main liquid outlet pipe via quick-connect fittings. One gas channel 203 of the manifold 2 is connected to a gas source via an air inlet connector, and the other gas channel 203 is connected to an external pipe via a liquid blowing connector, leading to a drain bucket or other collecting container. Ball valve switches are installed near the water collector on the main liquid inlet pipe, main liquid outlet pipe, gas source, and external pipe. Holding the handle 7, connect and press the female connector of the manifold 2 with the female connector of the diverter plate 1. Figure 5 As shown, the locking device 4 and the pull pin 3 complete self-locking. Open the switches on the liquid inlet pipe and the liquid outlet pipe to cool the mold. When changing the mold, close the switches on the liquid inlet pipe and the liquid outlet pipe, open the switches on the air source and the outer pipe to clean the water passage inside the mold. After the water passage is drained, close the switches on the air source and the outer pipe. At this time, simply press the pressing part 6, and the manifold 2 can be separated from the diverter 1. The whole process has low operation intensity and high operation efficiency.
