[0030] The present invention provides an automatic demoulding device for robot shell molding, which is mainly used for manufacturing demoulding of high-pressure molding robots and is convenient for users to perform demoulding operations after the high-pressure molding robots are molded.

[0031] In one embodiment of the present invention, Figures 1 to 3 As shown, it includes: a workbench 1, a mold box 4, a moving unit 6 and a connection box 10, the mold box 4 is arranged at the upper end of the workbench 1, the connection box 10 is movably arranged at the upper end of the mold box 4 through the moving unit 6, and the openings of the mold box 4 and the connection box 10 are arranged opposite to each other; the bottom end of the connection box 10 is provided with a clamping shaft 13, and the mold box 4 is provided with a clamping groove 14 corresponding to the clamping shaft 13;

[0032] A demoulding box 5 is provided inside the molding box 4, and a demoulding unit 7 is provided inside the demoulding box 5. The demoulding unit 7 includes a telescopic rod 71, a connecting plate 72 and a limiting column 73. One end of the telescopic rod 71 passes through the workbench 1, and the other end thereof is connected to the bottom end of the connecting plate 72. The limiting column 73 is provided at the top end of the connecting plate 72.

[0033] Specifically, the automatic demoulding device for robot high pressure molding includes a workbench 1, which provides a working platform to facilitate the connection of other components and ensure the normal operation of the automatic demoulding device. A mold box 4 and a connection box 10 are arranged on the workbench 1, and the connection box 10 can be moved up and down by a moving unit 6 to realize the opening and closing of the mold box 4 and the connection box 10. In the actual operation process, a control switch group 9 is set to realize the up and down movement of the mold box 4. When the mold box 4 moves downward to close with the connection box 10, the raw material is poured into the mold box 4, and the mold box 4 and the connection box 10 are opened and closed. The cavity formed by the connection box 10 and the gap formed by the surface of the demoulding box 5 form the shape of the robot shell. After the robot shell is formed, the connection box 10 is raised and separated from the mold box 4 by controlling the switch group 9. Since the bottom end of the connection box 10 is provided with a clamping shaft 13, and the mold box 4 is provided with a clamping groove 14, when the mold box 4 and the connection box 10 are closed, the clamping shaft 13 is clamped in the clamping groove 14, so that the mold box 4 and the connection box 10 can be connected together more stably, avoiding the phenomenon that the mold box 4 and the connection box 10 are offset during the molding process and causing damage to the robot shell. In the automatic demoulding device, in addition to forming the specific shape of the robot shell together with the inverting mold box 4 and the connecting box 10, the demoulding box 5 can also lift the demoulding box 5 through the demoulding unit 7 to realize the rapid demoulding of the robot shell after molding. Specifically, a demoulding unit 7 is provided in the demoulding box 5 for demoulding the robot shell after molding. After molding, the robot shell covers the upper end of the demoulding unit 7, and the telescopic rod 71 pushes the connecting plate 72 upward, and the connecting plate 72 drives the limiting column 73 to move upward together, so that the demoulding unit 7 is upward as a whole, so that the robot shell covering the upper end of the demoulding unit 7 is ejected, and the user only needs to remove the robot shell to complete the demoulding of the robot shell, and the operation steps are simpler.

[0034] Further, the moving unit 6 includes a driving member 61, a sliding block 62, a positioning member 63 and a first limiting rod 64. The sliding block 62 is provided at the upper end of the connection box 10. One end of the sliding block 62 is slidably connected to the first limiting rod 64, and the other end is slidably connected to the positioning member 63. The driving member 61 is provided at the top of the positioning member 63. In this way, when the mold needs to be opened or closed, it is achieved by the rise and fall of the connection box 10. Specifically, the two ends of the connection box 10 are slidably connected to the positioning member 63 and the first limiting rod 64 respectively, and the top of the positioning member 63 is also provided with a driving member 61. The driving member 61 can freely control the up and down movement of the sliding block 62, thereby realizing the up and down movement of the connection box 10 at the lower end of the sliding block 62. The driving member 61 can be driven by a motor, and the positioning member 63 can be a threaded rod.

[0035] Furthermore, if Figures 1 to 3As shown, it also includes a cooling unit 8, which is connected to the demoulding box 5; the cooling unit 8 includes a storage box 81, a connecting pipe 82, a pump body 83 and a water pipe 84, one end of the water pipe 84 is connected to the demoulding box 5, and the other end is connected to the pump body 83, and the pump body 83 is connected to the storage box 81 through the connecting pipe 82; the bottom end of the demoulding box 5 is provided with a drain pipe 11.

[0036] The cooling unit 8 is used for cooling during the molding process of the robot shell. Since the heat of the molten raw material is relatively high during the molding process, if the heat in the cavity formed by the connecting box 10 and the mold box 4 is not discharged in time during the molding process, the molding time of the robot shell will be very long, which is not conducive to production. Therefore, a cooling unit 8 is provided to discharge the heat in the cavity in time, which greatly shortens the molding time of the robot shell. Specifically, the pump body 83 extracts the liquid in the storage box 81 through the connecting pipe 82 and transports it to the demolding box 5. Since the robot shell is covered on the surface of the demolding box 5 during molding, the heat can be conducted from the heat on the upper surface of the demolding box 5 to the liquid, which is convenient for rapid cooling of the robot shell during molding. When the temperature of the liquid in the demolding box 5 rises, the cap 12 of the drain pipe 11 is opened, and the liquid in the demolding box 5 is discharged and then new liquid is injected, thereby realizing the cyclic cooling of the robot shell by the demolding box 5 during molding.

[0037] Furthermore, the connection box 10 is provided with a feed pipe 15 running through it. Specifically, the setting of the feed pipe 15 facilitates the addition of raw materials when the connection box 10 and the mold box 4 are closed, so that the robot high-pressure molding automatic demoulding device can not only realize the molding of solid raw materials, but also realize the molding of liquid raw materials, and the raw materials after hot melting are directly input into the connection box 10 for high-pressure molding, and the raw materials will not leak to the outside, and the robot shell can be obtained.

[0038] Furthermore, the mobile unit 6 also includes a fixed plate 3 and a support plate 2, one end of the fixed plate 3 is connected to the top of the first limiting rod 64, and the other end thereof is connected to the top of the positioning member 63, the driving member 61 passes through the fixed plate 3 and is connected to the positioning member 63, and the two ends of the support plate 2 are respectively connected to the fixed plate 3 and the workbench 1. The fixed plate 3 in this embodiment is mainly used to limit the movement stroke of the sliding block 62, and is fixed to the driving member 61, thereby avoiding direct contact between the sliding block 62 and the driving member 61 and extending the service life of the driving member 61. The support plate 2 located on one side of the workbench 1 serves to further fix the mobile unit 6, and its top end is connected to the fixed plate 3, and its bottom end is connected to the workbench 1, so as to prevent the fixed plate 3 from shifting to one side during use and affecting the continued operation of the mobile unit 6.

[0039] Furthermore, a second limiting rod 18 is further provided in the demoulding box 5, and the second limiting rod 18 passes through the connecting plate 72 and is connected to the inner wall of the demoulding box 5. It can be understood that Figure 3 As shown, the second limiting rod 18 realizes the second fixation of the connecting plate 72, and shares part of the force when the telescopic rod 71 pushes the demolding box 5 upward, and together with the limiting column 73 and the telescopic rod 71, fixes the connecting plate 72 and the demolding box 5 to prevent the connecting plate 72 from falling, thereby extending the service life of the demolding unit 7.

[0040] Further, the clamping shaft 13 is located at the four corners of the connection box 10, and the clamping slot 14 is located at the four corners of the mold box 4. In this way, the clamping shaft 13 and the clamping slot 14 are arranged at the corners, which can save working space and will not damage the specific structure of the robot shell.

[0041] Furthermore, the bottom end of the workbench 1 is provided with a leg 16. Figures 1 to 3 As shown, the water pipe 84 is located at the lower end of the workbench 1 , so it is necessary to provide a support leg 16 to increase the vertical height of the workbench 1 for accommodating the water pipe 84 and the drainage pipe 11 .

[0042] Furthermore, a base 17 is provided at the bottom of the leg 16, and the storage box 81 and the pump body 83 are both located at the upper end of the base 17. The base 17 makes the entire robot high pressure molding automatic demoulding device more integrated and makes the device more convenient during transportation.

[0043] When the automatic demolding device for the entire robot shell molding is used in specific use: cold water is stored in the storage box 81, and then the drive member 61 is controlled to work by the control switch group 9, thereby driving the positioning member 63 to rotate, and the rotation of the positioning member 63 drives the sliding block 62 to move downward, so that the connecting box 10 will move downward. When the lower end surface of the connecting box 10 is in contact with the upper end surface of the inverted mold box 4, the drive member 61 is controlled to stop working by the control switch group 9. At this time, the four card shafts 13 installed on the connecting box 10 are carded into the four card slots 14 opened on the inverted mold box 4, and then the hot-melt material is injected into the interior of the connecting box 10 through the feeding pipe 15. The raw materials entering the connecting box 10 are located in the interlayer of the inverted mold box 4, the connecting box 10 and the demolding box 5, and form the shape of the robot shell. Then, the cold water in the storage box 81 is transported to the interior of the demolding box 5 through the water pipe 84 by controlling the pump body 83 to enter the demolding box 5. The cold water inside the mold box 5 absorbs the heat of the hot-melt material and turns into hot water. Then the cap 12 is removed and the hot water is discharged through the drain pipe 11. The pump body 83 continues to work so that the water pipe 84 continues to transport cold water to the inside of the demolding box 5, thereby greatly accelerating the cooling time of the hot-melt material. After the hot-melt material is cooled and formed, the telescopic rod 71 is controlled by the control switch group 9. The telescopic rod 71 drives the connecting plate 72 inside the demolding box 5 to move upward. The connecting plate 72 moves upward and then drives the three connecting columns 73 to move upward. When the three connecting columns 73 move upward, the demolding box 5 moves upward, so the robot shell located on the surface of the demolding box 5 is separated from the connecting box 10, and then the robot shell is removed to realize the demolding process of the entire robot shell. The above device can realize automatic demolding of the molded robot shell, avoid the damage of the robot shell caused by manual demolding, and can greatly shorten the cooling time of the molded product.

[0044] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
