Description

Technical Field

[0001] The present invention relates to the technical field of mold surface treatment, and particularly relates to a surface treatment device for mold production. Background Art

[0002] When processing molds, pre-cleaning is required to remove stains on the mold surface. Otherwise, the stains on the workpiece surface before and after heat treatment directly enter the furnace for heating, volatilization, and combustion, which easily causes air pollution in the workshop.

[0003] Chinese Patent CN215825741U discloses a processing and treatment device for injection mold production. By setting an electro-hydraulic mechanism on one side of the housing, the cross bar is driven to move back and forth by the electro-hydraulic mechanism, so as to shake the injection mold placed in the placement cavity formed by the mesh limit plate, and shake while cleaning, which can prevent sundries from adsorbing on the surface of the injection mold.

[0004] The above device supports the mold through a metal mesh frame, and then places the mold in the water tank for cleaning. However, in actual use, the mold cannot continuously enter and exit the water tank along with the production line transportation. This results in the need to lift the metal mesh frame each time to achieve the entry and exit of the mold from the water tank, which has certain deficiencies.

[0005] Therefore, it is necessary to provide a surface treatment device for mold production to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a surface treatment device for mold production to solve the problem in the above background art that the existing device supports the mold through a metal mesh frame and then places the mold in the water tank for cleaning. However, in actual use, the mold cannot continuously enter and exit the water tank along with the production line transportation, which results in the need to lift the metal mesh frame each time to achieve the entry and exit of the mold from the water tank.

[0007] Based on the above idea, the present invention provides the following technical solution: A surface treatment device for mold production, including two chains arranged oppositely and a support component installed between the two chains. A water tank is arranged between the two chains, and the support component is located above the water tank. The support component includes a main support plate and a secondary support plate that are vertically distributed and can slide relative to each other. The main support plate is connected to the chain and can rotate relative to the chain. A connection block is fixedly installed on the chain, and a round shaft elastically connected to the connection block is arranged on the main support plate. A first positioning block and a second positioning block are respectively arranged on the left and right sides of the connection block on the chain; Initially, the main support plate is lapped at the first positioning block. When the chain drives the main support plate to move to one side of the water tank, the main support plate can be disengaged from the first positioning block and deflected downward into the water tank. When the secondary support plates at the two support assemblies are in a horizontal state and fit together inside the water tank, the main support plate can drive the mold to move between the two secondary support plates.

[0008] As a further solution of the present invention: Blocks are elastically connected to the inner sides of the first positioning block and the second positioning block. The bottom surface and the front and rear surfaces of the block are all provided as inclined surfaces. A strip-shaped groove matching the block is formed on one side of the main support plate close to the chain. In the initial state, the block at the first positioning block is inserted into the strip-shaped groove.

[0009] As a further solution of the present invention: A cross plate is fixedly installed inside the water tank. After the main support plate deflects to a vertical state, the secondary support plate can fall onto the cross plate. In the initial state, a set of support assemblies in an unloaded state are clamped on the cross plate.

[0010] As a further solution of the present invention: A pressing plate is elastically connected to one side of the secondary support plate close to the main support plate, and a detection unit is arranged between the pressing plate and the secondary support plate. An electromagnet matching the round shaft is arranged on the main support plate. The round shaft is made of iron. When the pressing plate on the secondary support plate is in a compressed state, the detection unit can control the electromagnet to be powered off, so that the round shaft can pop out and be inserted into the round hole of the connecting block.

[0011] As a further solution of the present invention: A positioning post is elastically connected to one side of the secondary support plate away from the main support plate. A positioning hole matching the positioning post is formed on the top surface of the cross plate. The positioning post on the secondary support plate located inside the water tank and in an unloaded state is inserted into the positioning hole. A magnetic strip is slidably arranged at one end end face of the secondary support plate. A traction rope is fixedly arranged between the magnetic strip and the positioning post. A magnetic plate is fixedly embedded at one end end face of the secondary support plate away from the magnetic strip. The opposite sides of the magnetic strip and the magnetic plate have different magnetic poles.

[0012] As a further solution of the present invention: A pull rod is slidably connected to the top surface of the first positioning block. A pull rope is fixedly arranged between the pull rod and the block at the first positioning block. A top rod matching the pull rod is arranged above the chain. One end of the top rod is provided as a slope. During the process of the chain driving the first positioning block to move, the pull rod can move above the top rod through the slope.

[0013] As a further solution of the present invention: An avoidance groove is arranged at one end of the main support plate close to the secondary support plate, and the secondary support plate is located at the avoidance groove.

[0014] As a further solution of the present invention: sliding grooves are formed on both sides of the auxiliary support plate, sliding blocks that are slidably matched with the sliding grooves are fixedly arranged on both inner side walls of the avoidance groove, a convex block is elastically connected to the end face of the sliding block, a plurality of notches that are matched with the convex block are formed on the bottom surface inside the sliding groove, and an inclined extrusion surface is arranged at one end of the convex block located in the notch.

[0015] As a further solution of the present invention: a circular hole for installing a positioning post is formed on the auxiliary support plate.

[0016] As a further solution of the present invention: a stepped hole that is slidably matched with the round shaft is formed on the main support plate, and the electromagnet is fixed inside the stepped hole.

[0017] Compared with the prior art, the beneficial effect of the present invention is that when the auxiliary support plate originally carrying the mold loses the mold, the main support plate at this support assembly can be separated from the chain. After that, when the chain drives the main support plate originally in the water tank to move, through the limit of the side wall of the water tank on the main support plate, the main support plate can deflect upward and cooperate with the second positioning block. In this way, the operation of the mold entering and leaving the water tank can be realized during the transportation of the mold, so that the mold can be continuously cleaned, and the overall operation is more convenient.

[0021] As Figures 1-10 shown, a surface treatment device for mold production includes two relatively arranged chains 1 and a support assembly installed between the two chains 1. Referring to Figure 1 shown, the support assembly includes a vertically distributed main support plate 7 and a sub-support plate 8. The main support plate 7 is connected to the chain 1 and can rotate relative to the chain 1. The main support plate 7 and the sub-support plate 8 are slidably matched; Combining again with Figure 1 shown, in order to install the main support plate 7 on the chain 1, a connecting block 3 cooperating with the main support plate 7 is fixedly installed on the chain 1 in this solution. Elastic shafts 702 cooperating with the connecting block 3 are elastically connected to both the front and rear side surfaces of the main support plate 7. The round shafts 702 are located at positions of the main support plate 7 close to the ends. Specifically, a round hole cooperating with the round shaft 702 is provided at the inner end surface of the connecting block 3, so that the round shaft 702 can be inserted into the round hole and rotatably cooperate with it. In order to support the main support plate 7, a first positioning block 4 and a second positioning block 5 are respectively arranged on the left and right sides of the connecting block 3 on the chain 1. The first positioning block 4 and the second positioning block 5 are both fixedly connected to the chain 1. Specifically, the connecting block 3, the first positioning block 4, and the second positioning block 5 can all be fixed on the outer link plate of the chain 1. Since fixedly installing a rigid member on the chain 1 is a mature technical means in the mechanical field, the connection structure between the connecting block 3, the first positioning block 4, the second positioning block 5 and the chain 1 will not be elaborated here.

[0022] Combine Figures 7-10 As shown, the inner side surfaces of the first positioning block 4 and the second positioning block 5 are elastically connected with a stopper 11, referring to Figure 9 As shown, the bottom surface and front and back surfaces of the stopper 11 located at one end outside the first positioning block 4 or the second positioning block 5 are all set as inclined surfaces 1101, and only the top surface of the stopper 11 is a horizontal surface. A strip groove 701 that cooperates with the stopper 11 is opened on the side of the main support plate 7 close to the chain 1. In the initial state, one end of the main support plate 7 is on the first positioning block 4, and the stopper 11 at the first positioning block 4 is in the strip groove 701, so as to maintain the stability of the main support plate 7; A water tank 6 is provided between the two chains 1, and the above-mentioned support assembly is located above the water tank 6 (the circular shaft 702 on the main support plate 7 is located above the water tank 6). In actual use, an ultrasonic generator and a transducer can be selectively installed on the bottom surface of the water tank 6 to achieve cleaning of the mold. Of course, different solvents can also be selected to clean the mold surface. During use, the mold to be cleaned is placed on the main support plate 7. As the chain 1 moves, the main support plate 7 can be driven to move to the side of the water tank 6. The bottom surface of the main support plate 7 can contact the top end surface of the water tank 6. Figure 4 As shown, when the stopper 11 on the first positioning block 4 is separated from the strip groove 701 on the main support plate 7, the main support plate 7 will deflect downward and fall on the side of the water tank 6. At this time, as the chain 1 continues to move, the main support plate 7 can continue to deflect downward until it is in a vertical state. At this time, the mold falls on the auxiliary support plate 8 and is in the water tank 6. Furthermore, a cross plate 601 is fixedly installed inside the water tank 6. When the main support plate 7 is deflected to a vertical state, the auxiliary support plate 8 falls on the cross plate 601 and can be engaged with the cross plate 601. Figure 5 As shown, in the initial state, a group of unloaded support assemblies are arranged in the water tank 6, and the main support plate 7 on this support assembly is located on the left side of the auxiliary support plate 8. Specifically, when the support assembly is in the unloaded state, the main support plate 7 at the unloaded support assembly can be disconnected from the chain 1. Therefore, as the chain 1 moves, the main support plate 7 at the support assembly carrying the mold can move synchronously with the chain 1 and push the mold on the auxiliary support plate 8 to move, so that the mold moves to the unloaded support assembly. Subsequently, as the chain 1 moves, it can drive the support assembly carrying the mold to move again. The main support plate 7 is limited by the side wall of the water tank 6 so that the main support plate 7 can be flipped to a horizontal state as the chain 1 moves. During this process, the cleaned mold can fall back on the main support plate 7. During the whole process, no other power structure intervention is required, so that the mold can enter the water tank 6 for cleaning and be removed from the water tank 6 during the movement of the chain 1.

[0023] On one side of the secondary support plate 8 close to the main support plate 7, there is an elastic connection with a pressing plate 803, and a detection unit 804 is arranged between the pressing plate 803 and the secondary support plate 8. Specifically, an installation groove for installing the pressing plate 803 is formed on the secondary support plate 8, so that the pressing plate 803 is elastically connected to the installation groove through a third spring, and the detection unit 804 is installed at the inner bottom end of the installation groove. An electromagnet 703 is arranged on the main support plate 7 and is matched with the round shaft 702, and the round shaft 702 is made of iron. In the initial state, the mold to be cleaned is placed on the main support plate 7. During actual use, when the main support plate 7 is lapped on the first positioning block 4 or the second positioning block 5, one end of the main support plate 7 close to the first positioning block 4 or the second positioning block 5 can be in a lower position, so that the mold has a tendency to slide towards the secondary support plate 8, thereby enabling the mold to press the pressing plate 803, and then controlling the electromagnet 703 to be powered off through the detection unit 804, so that the round shaft 702 can pop out and be inserted into the round hole, so as to maintain the connection between the main support plate 7 and the chain 1.

[0024] On one side of the secondary support plate 8 away from the main support plate 7, there is an elastic connection with a positioning post 807. Referring to Figures 7-8 , Figure 10 As shown, a positioning hole 6011 matching the positioning post 807 is formed on the top surface of the cross plate 601. The positioning post 807 on the secondary support plate 8 located in the water tank 6 and in the no-load state is inserted into the positioning hole 6011, so that the no-load secondary support plate 8 can be locked with the cross plate 601. Furthermore, in combination with Figures 7-10 , Figure 12 As shown, a magnetic strip 801 is slidably arranged at the end face of the secondary support plate 8 close to the positioning post 807. A traction rope 15 is fixedly arranged between the magnetic strip 801 and the positioning post 807. The traction rope 15 passes through the secondary support plate 8 and is slidably matched with it. A magnetic plate 806 is fixedly embedded at the end face of the secondary support plate 8 away from the magnetic strip 801. When the magnetic strips 801 on the two secondary support plates 8 are aligned with the magnetic plate 806, the opposite sides of the magnetic strip 801 and the magnetic plate 806 have different magnetic poles.

[0025] In combination with Figures 1-4 As shown, a pull rod 401 is slidably connected to the top surface of the first positioning block 4. The pull rod 401 is in an inverted L shape. A pull rope 10 is fixedly arranged between the pull rod 401 and the stop block 11 at the first positioning block 4. The pull rope 10 passes through the first positioning block 4 and is slidably matched with it. A top rod 9 matching the pull rod 401 is arranged above the chain 1. Referring to Figure 2As shown, one end of the ejector rod 9 is provided with a slope 901. During the process of the chain 1 driving the first positioning block 4 to move, the pull rod 401 can move above the ejector rod 9 through the slope 901. During this process, the pull rod 401 can pull the stopper 11 through the pull rope 10, so that the stopper 11 at the first positioning block 4 can be disengaged from the strip groove 701 at the main support plate 7.

[0026] As Figure 4 shown, in the initial state, a group of unloaded support components are located in the water tank 6, and the positioning posts 807 on the secondary support plate 8 of this support component are inserted into the positioning holes 6011. One end of the main support plate 7 located at the chain 1 away from the connection block 3 is lapped on the first positioning block 4, so that the stopper 11 on the first positioning block 4 is inserted into the strip groove 701 to maintain the stable cooperation between the main support plate 7 and the chain 1. When the chain 1 drives the main support plate 7 to move to one side of the water tank 6 and contacts the top surface of the water tank 6, the pull rod 401 moves to the slope 901 of the ejector rod 9. During the movement of the chain 1, the pull rod 401 can move above the ejector rod 9 along the slope 901, so that the stopper 11 at the first positioning block 4 is disengaged from the strip groove 701 on the main support plate 7. At this time, the main support plate 7 can deflect downward around the round shaft 702 and fall onto the side of the water tank 6, as specifically shown in Figure 4 shown; As the chain 1 continues to move, the main support plate 7 can deflect downward and finally be in a vertical state. When the main support plate 7 completely falls into the water tank 6 and is in a vertical state, the secondary support plate 8 falls onto the cross plate 601 and is in a horizontal state. Referring to Figure 5 shown, when the chain 1 continues to drive the main support plate 7 and the secondary support plate 8 to move, the secondary support plate 8 carrying the mold will fit with the unloaded secondary support plate 8 in the water tank 6. Through the suction force between the magnetic plate 806 and the magnetic strip 801, the magnetic strip 801 can pull the positioning post 807 through the traction rope 15, so that the positioning post 807 on the unloaded secondary support plate 8 can be removed from the positioning hole 6011, and the unloaded secondary support plate 8 is disengaged from the cross plate 601. When the chain 1 drives the support component carrying the mold to move so that the positioning post 807 on the secondary support plate 8 is aligned with the positioning hole 6011 on the cross plate 601, the secondary support plate 8 carrying the mold can be locked on the cross plate 601 through the cooperation of the positioning post 807 and the positioning hole 6011. Since the main support plate 7 and the secondary support plate 8 are in sliding fit, during the process of the chain 1 driving the main support plate 7 to move, the mold on the secondary support plate 8 can be pushed towards the unloaded secondary support plate 8 in the water tank 6, so that the mold is finally pushed onto the secondary support plate 8 that was originally in the water tank 6 and was in an unloaded state, and the secondary support plate 8 that originally carried the mold is locked on the cross plate 601; When the mold enters the unloaded auxiliary support plate 8, it can press the pressure plate 803, and then the detection unit 804 controls the electromagnet 703 to be in a power-off state, so that the circular shaft 702 on the main support plate 7 originally in the water tank 6 can pop out. When the chain 1 drives the connecting block 3 through the main support plate 7, the circular shaft 702 can pop out and be inserted into the connecting block 3. Figure 9 、 Figure 14 As shown, the side edges of the inner end faces of the first positioning block 4, the second positioning block 5 and the connecting block 3 are all provided with rounded corners 1102 or chamfers, so as to avoid interference between the first positioning block 4, the second positioning block 5 and the connecting block 3 and the circular shaft 702 when they move, so that the main support plate 7 originally in the water tank 6 can be connected to the chain 1, and the auxiliary support plate 8 originally carrying the mold can separate from the main support plate 7 at this support assembly after losing the mold. Afterwards, when the chain 1 drives the main support plate 7 originally in the water tank 6 to move, the main support plate 7 is limited by the side wall of the water tank 6, so that the main support plate 7 can deflect upward. When the main support plate 7 deflects upward to the second positioning block 5, the side edge of the main support plate 7 can squeeze the inclined surface 1101 on the stopper 11, so that the stopper 11 can enter the strip groove 701, which is conducive to the main support plate 7 being stably placed between the connecting block 3 and the second positioning block 5. At this point, the entire process of the mold from entering the water tank 6 to moving out of the water tank 6 is completed.

[0027] like Figures 1-10 As shown, after the mold is cleaned and moved out of the water tank 6, the chain 1 drives the mold to the specified position. At this time, the support assembly and the mold can be removed from the chain 1 together. Of course, a control unit for controlling the electromagnet 703 can also be arranged on the main support plate 7. In actual operation, only when the pressure plate 803 bounces upward without triggering the detection unit 804 and the control unit is in a non-pressed state, the electromagnet 703 can be in an energized state. At this time, the support assembly can be disassembled. When you do not want to disassemble the support assembly, just press the control unit. At this time, regardless of whether there is a mold on the support assembly, the support assembly is connected to the chain 1.

[0028] Reference Figure 1 As shown, a side plate 2 is provided on the outside of the chain 1, and a sprocket meshing with the side plate 2 is provided on the inside of the chain 1, and a rotating shaft is fixedly installed on the sprocket, and the rotating shaft passes through the side plate 2 and is rotatably connected to the side plate 2. In actual use, a motor can be installed at the side plate 2, and the output shaft of the motor and one end of the rotating shaft passing through the side plate 2 are connected by a belt or chain 1 to drive the chain 1 to rotate. A fixing rod is fixedly provided between the side of the water tank 6 close to the side plate 2 and the side plate 2 to connect the water tank 6 to the side plate 2, and the side plate 2 can be installed on the ground through a support frame.

[0029] During actual use, a support bar can be fixedly installed on the inner side of the side plate 2 so that the chain 1 falls on the support bar, which is conducive to the stable movement of the chain 1.

[0030] Reference Figure 2 As shown, the push rod 9 is fixedly connected to the side plate 2 via a bracket.

[0031] The first positioning block 4 is provided with an installation groove that slides with the pull rod 401 . The first positioning block 4 and the second positioning block 5 are both provided with grooves that slide with the stop block 11 . A spring is fixed between the inner end surface of the groove and the stop block 11 .

[0032] Combine Figures 6-10 As shown, an insertion rod 805 is fixedly provided at one end of the auxiliary support plate 8 away from the magnetic strip 801, and a mounting hole is provided on the outer peripheral wall of the insertion rod 805. A protrusion 8051 is slidingly provided inside the mounting hole, and a first spring is fixedly provided between the protrusion 8051 and the inner end surface of the mounting hole. Figure 6 As shown, the end of the protrusion 8051 away from the insertion rod 805 is a spherical structure, and the side of the auxiliary support plate 8 close to the magnetic strip 801 is provided with a socket 802 that cooperates with the insertion rod 805. The cross-section of the socket 802 is T-shaped. When the two auxiliary support plates 8 are fitted together, the insertion rod 805 can be inserted into the socket 802, and the cooperation between the protrusion 8051 and the socket 802 makes the two auxiliary support plates 8 stably connected, which can prevent the auxiliary support plate 8 originally in the water tank 6 from moving relative to the cross plate 601 during the process of the main support plate 7 pushing the mold to move. Since one end of the protrusion 8051 is a spherical structure, when the chain 1 drives the main support plate 7 and the auxiliary support plate 8 to move, the protrusion 8051 can be moved out of the socket 802, thereby separating the two auxiliary support plates 8.

[0033] Reference Figure 9 As shown, by setting the inclined surface 1101, on the one hand, the main support plate 7 can be prevented from interfering with the stop block 11 during the upward deflection process, and on the other hand, the first positioning block 4 and the second positioning block 5 can be prevented from interfering with the circular shaft 702 on the main support plate 7 retained in the water tank 6 during the movement with the chain 1.

[0034] Reference Figure 10 As shown, an avoidance groove is provided at one end of the main support plate 7 close to the auxiliary support plate 8, and the auxiliary support plate 8 is located in the avoidance groove. When the main support plate 7 pushes the mold to move, the avoidance groove can prevent the pressing plate 803 from bouncing upward, thereby further pushing the mold onto the auxiliary support plate 8. When the main support plate 7 and the pressing plate 803 are staggered, the pressing plate 803 can bounce upward. Furthermore, the auxiliary support plate 8 is provided with a slide groove 809 on both sides, and the two side walls inside the avoidance groove are fixedly provided with a slider 13 that slides with the slide groove 809.Figure 11 As shown, a rectangular groove is formed on the end face of the slider 13. A convex block 14 is slidably arranged in the rectangular groove, and a limiting spring is fixedly arranged between the convex block 14 and the inner end face of the rectangular groove. Multiple notches 808 matched with the convex block 14 are formed on the inner bottom surface of the chute 809. Tilted extrusion surfaces 12 are arranged on both sides of one end of the convex block 14 located inside the notch 808. Through this structure, the stability of the cooperation between the secondary support plate 8 and the main support plate 7 can be maintained, so that during the process of the chain 1 transporting the mold, the secondary support plate 8 will not move downward relative to the main support plate 7 due to gravity. Only when the secondary support plate 8 is locked with the cross plate 601, during the process of the chain 1 driving the main support plate 7 to move, the side edge of the notch 808 can extrude the extrusion surface 12 of the convex block 14, so that the convex block 14 moves out of the notch 808.

[0035] A circular hole slidably matched with the positioning post 807 is formed on the secondary support plate 8, and the positioning post 807 is elastically connected in the circular hole through a second spring. In addition, a receiving groove slidably matched with the magnetic strip 801 is also formed on the secondary support plate 8.

[0036] Refer to Figure 13 As shown, a stepped hole slidably matched with the round shaft 702 is formed on the main support plate 7. The electromagnet 703 is fixed at the inner end face of the stepped hole. The cross section of the round shaft 702 is T-shaped, and a tension spring is arranged between the inner end face of the stepped hole and the end face of the round shaft 702. When the electromagnet 703 loses power, the round shaft 702 can pop out. The above detection unit 804 and the control unit can both be normally closed switches, and the detection unit 804 and the control unit can both control the electromagnet 703 by means of electrical connection or wireless connection. Since it is a mature technical means in the electrical field, it will not be elaborated here.
