DETAILED DESCRIPTION

[0017] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-2An automated core pressing system for high-temperature alloy precision casting is shown, in which a represents an electronic control system, including a ceramic injection molding machine 1 with an electronic control system, a vacuum cleaner 201 located on the right side of the ceramic injection molding machine 1, and a mold release agent barrel 202. The front end of the ceramic injection molding machine 1 is fixedly installed with an injection molding platform 102 and an injection molding unit, the injection molding unit is located directly above the injection molding platform 102, the injection molding unit includes an injection molding mold located at the upper end of the injection molding platform 102 and a clamping assembly located above the injection molding mold, and the clamping assembly includes a carrier plate 5 fixedly connected to the ceramic injection molding machine 1 3. A clamping cylinder 51 is fixedly connected to the upper end of the carrier plate 53. The extended end of the clamping cylinder 51 movably penetrates the carrier plate 53 and is fixedly connected to a booster plate 54. The four corners of the upper end of the booster plate 54 are fixedly connected to guide rods 52 that movably penetrate the carrier plate 53. A protective cover 101 is also fixedly connected to the front end of the ceramic injection molding machine 1. The clamping assembly is located inside the protective cover 101. The injection mold includes an injection mold 41 located on the injection platform 102 and an injection movable mold 42 connected to the middle of the lower end of the booster plate 54. The injection mold 41 and the injection movable mold 42 match each other. The upper end of the injection molding platform 102 is also fixedly connected to a pick-and-place robot 21 and a cleaning robot 22. A washing and sweeping block is also installed at the end of the cleaning robot 22. A suction nozzle and a cleaning brush are respectively installed at the lower end of the washing and sweeping block. The pick-and-place robot 21 and the cleaning robot 22 are respectively located on the left and right sides of the injection molding mold. The upper end of the injection molding platform 102 is also fixedly installed with a visual orthopedic unit, which is located in front of the injection molding mold. The vacuum cleaner 201 and the release agent barrel 202 are respectively connected to the cleaning robot 22 through pipelines. The upper end of the injection molding platform 102 is also fixedly connected to a burning bowl 103, which is located in front of the pick-and-place robot 21. like Figure 3 The visual orthotic unit includes an orthotic component and a visual component located in front of the orthotic component, the visual component includes a front bracket 31 fixedly connected to the injection platform 102 and a high-definition camera rotatably installed on the top of the front bracket 31, the orthotic component includes a rear bracket 32 ​​fixedly connected to the injection platform 102, an orthotic fixed film 401 is installed at the lower end of the rear bracket 32, and an orthotic movable mold 402 is connected to the upper end of the rear bracket 32 ​​through an electric cylinder, the orthotic movable mold 402 is located directly above the orthotic fixed film 401, and the cavity shape of the orthotic fixed film 401 and the orthotic movable mold 402 close to each other The cavity shape of the end faces of the fixed mold 401 and the injection movable mold 42 close to each other is consistent with the cavity shape of the fixed mold 41 and the injection movable mold 42, thereby effectively ensuring its orthotic effect on the core.

[0019] When the core is pressed, the ceramic injection molding machine 1 first controls the mold clamping assembly to close the mold of the fixed die 41 and the movable die 42 and then performs the injection work. After the injection, the mold clamping assembly first moves upward to drive the movable die 42 to separate from the fixed die 41, so that the formed core is exposed on the fixed die 41. At this time, the electronic control system controls the pick-and-place robot 21 to work, which first clamps the core on the fixed die 41 and places the core on the orthopedic fixed film 401. At this time, the high-definition camera captures the image information of the core on the orthopedic fixed film 401, thereby judging Whether the position of the broken core is accurate, when the position is inaccurate, the electronic control system controls the pick-and-place robot 21 to adjust it according to the image information until the position is accurate, and then the electric cylinder controls the orthopedic movable mold 402 to move down and gradually close the mold with the orthopedic fixed film 401 to correct the core. After correction, the pick-and-place robot 21 puts the core into the burning bowl 103, and the molding of a core is completed, and then the above process is repeated to realize automated and continuous core pressing and molding, thereby effectively ensuring the injection efficiency and the production efficiency of the core.

[0020] In the above-mentioned automated core pressing system for high-temperature alloy precision casting, the automated operation of ceramic core injection can be realized, effectively reducing the dependence on manual labor and the impact of human factors on product quality, so as to improve production efficiency. Moreover, the entire molding process is integrated into one device, which greatly reduces the floor space occupied and reduces cost investment compared to the existing technology in which multiple devices cooperate with each other.

[0021] like Figure 4 The die 41 is mounted on the injection molding platform 102 via an electric slide rail. Figure 5 The injection mold 42 is connected to the booster plate 54 through a quick-change unit. The quick-change unit includes a double-section column 61 fixedly connected to the upper end of the injection mold 42, four positioning rods 62 respectively fixedly connected to the four corners of the upper end of the injection mold 42, and a positioning hole 601 drilled at the lower end of the booster plate 54 to match the positioning rod 62. The double-section column 61 includes a fixed polygonal section 611 fixedly connected to the injection mold 42 and a movable polygonal section 612 rotatably connected to the fixed polygonal section 611. Figure 6 A quick-change groove is bored at the lower end of the boost plate 54, the double-section column 61 matches the quick-change groove, an electromagnetic sheet is fixedly connected to the top of the positioning hole 601, and the electromagnetic sheet and the positioning rod 62 are mutually adsorbed after power is turned on. The quick-change groove includes a limit groove 701 and a transposition groove 702 located above the limit groove 701 and connected to the limit groove 701. A transposition rotary sleeve 703 is connected to the inside of the transposition groove 702 through an electric shaft, such as Figure 7 , and the internal shape of the transposition rotary sleeve 703 is consistent with the limiting groove 701.

[0022] When the injection mold needs to be replaced, the new injection mold is first placed on the electric slide rail, and then the transposition rotary sleeve 703 is controlled to rotate, and the fixed polygonal section 611 of the movable polygonal section 612 is driven to coincide with the movable polygonal section 612. At this time, the limit groove 701 and the cavity edge inside the transposition rotary sleeve 703 are aligned and coincide with each other. At this time, the booster plate 54 is controlled to move downward through the mold clamping assembly until the injection movable mold 42 contacts the injection fixed mold 41, and then the electromagnetic piece is controlled to be powered off, so that the adsorption relationship between the positioning rod 62 and the positioning hole 601 is contacted, and then the booster plate 54 is controlled to move upward. Fig. 9 , the injection mold 42 can be separated from the booster plate 54. At this time, the electric control system controls the electric slide rail to work, so that the old injection mold is away from the bottom of the booster plate 54, and the new mold gradually approaches the bottom of the booster plate 54. After the new mold reaches the target position, the electric slide rail stops working, and then the mold clamping assembly controls the booster plate 54 to move down again, so that the positioning rod 62 is inserted into the positioning rod 62, and the double-section column 61 is inserted into the quick-change groove. At this time, the electromagnetic sheet is energized to absorb the positioning rod 62, so that the injection mold 42 is temporarily fixed. Figure 8 Then, the transposition rotary sleeve 703 is controlled to rotate, thereby driving the moving polygonal section 612 to rotate and be misaligned with the fixed polygonal section 611, so that the double-section column 61 is stuck in the quick-change groove. At this time, the electromagnetic piece is controlled to be powered off to complete the replacement of the injection mold. Compared with the prior art, the replacement of the injection mold does not require complicated manual operation, and can be automatically and quickly replaced. The time consumption of the entire process is significantly reduced, effectively reducing the downtime, thereby ensuring the injection efficiency of the core.

[0023] The fixed polygon section 611 and the movable polygon section 612 are both the same regular polygons and match the limiting groove 701. The thickness of the fixed polygon section 611 is consistent with the vertical span of the limiting groove 701, and the thickness of the movable polygon section 612 is consistent with the internal depth of the replacement rotary sleeve 703. After the movable polygon section 612 and the fixed polygon section 611 are misaligned, the two parts can be stably confined in the quick-change groove, thereby effectively ensuring the stability of the injection movable mold 42, making it less likely to loosen during mold closing and injection, thereby reducing the defective rate.

[0024] The second implementation method: Based on the first embodiment, this embodiment adds a deviation measuring unit, and the rest of the parts are consistent with the first embodiment.

[0025] Fig.10As shown, a deflection measuring unit is also provided between the injection movable mold 42 and the booster plate 54, and embedded grooves are drilled on the upper end of the injection movable mold 42 and inside the transposition groove 702, and the deflection measuring unit includes an upper laser rangefinder 81 and a lower laser rangefinder 82 respectively installed in the two embedded grooves, a light-transmitting rod 801 fixedly passing through the transposition rotary sleeve 703, and two eccentric measuring plates 9 located directly below the light-transmitting rod 801, and the upper end of the light-transmitting rod 801 is located on the upper side of the corresponding embedded groove, and a deflection measuring hole 802 is drilled on the booster plate 54 and is located directly below the upper laser rangefinder 81. The two eccentric measuring plates 9 are fixedly connected to the deflection measuring hole 802, and the deflection measuring hole 802 is opposite to one of the vertices of the limiting groove 701, and the light-transmitting rod 801 is opposite to one of the vertices of the inner wall of the transposition rotary sleeve 703. The light-transmitting rod 801 is a hard transparent structure, and the inner diameter of the deflection measuring hole 802 is the diameter of the light-transmitting rod 801. 2-3 times of that, through the setting of the deflection measuring unit, when changing the mold, first control the electromagnetic sheet to be energized so that it generates an adsorption force on the positioning rod 62, and then control 73 to rotate in the opposite direction to the angle of rotation during the previous mold change, so that the light-transmitting rod 801 and the deflection measuring hole 802 are coaxial, so that the laser emitted by the upper laser rangefinder 81 can simultaneously penetrate the light-transmitting rod 801 and the deflection measuring hole 802 and fall on the injection molding platform 102. At this time, the data is relatively large, and when there is an offset between the light-transmitting rod 801 and the deflection measuring hole 802, when the offset is too large, the two are completely misaligned. At this time, the laser is directly irradiated on the bottom wall of the transposition groove 702, and the data is small. When the offset is small, the laser emitted by the upper laser rangefinder 81 will not pass through the axis of the eccentric measuring plate 9 after passing through the light-transmitting rod 801, but will fall on the eccentric light-transmitting plate 92. When the light-transmitting rod 801 is offset clockwise relative to the deflection measuring hole 802, such as Fig.11 , the laser will pass through the upper eccentric light-transmitting plate 92 and fall on the lower plate 91. When it is offset counterclockwise, the laser will directly fall on the upper plate 91. At this time, the difference between the two data is the distance between the two eccentric measuring plates 9. According to the data of the upper laser rangefinder 81, the electric control system can control the transposition rotary sleeve 703 to make corresponding fine adjustments to make the light-transmitting rod 801 and the deflection measuring hole 802 coaxial. After being coaxial, the lower laser rangefinder 82 on the new injection mold is controlled to start synchronously and pass through the electric slide rail. The new injection mold is controlled to move toward the bottom of the booster plate 54 until the lower laser rangefinder 82 is coaxial with the upper laser rangefinder 81. At this time, the laser data generated by the upper laser rangefinder 81 and the lower laser rangefinder 82 are the same, which means that the injection mold has reached the bottom of the booster plate 54. At this time, the booster plate 54 can be controlled to move downward so that the positioning rod 62 and the double-section column 61 can be accurately inserted into the corresponding positioning hole 601 and the quick-change groove to achieve accurate mold change, thereby effectively ensuring the mold change efficiency and reducing downtime.

[0026] like Fig.11, b in the figure indicates the moving path of the laser generated by the light-transmitting rod 801 as the rotation sleeve 703 is rotated, and c indicates the laser. The eccentric measuring plate 9 includes a plate body 91, an eccentric light-transmitting plate 92 fixedly embedded in the plate body 91, and a concentric light-transmitting plate 93 fixedly embedded on the eccentric light-transmitting plate 92. The plate body 91 is a non-transparent structure, and the eccentric light-transmitting plate 92 and the concentric light-transmitting plate 93 are both transparent structures; as shown in FIG. Figure 11-12 The concentric light-transmitting plate 93, the plate body 91 and the light-transmitting rod 801 are coaxially arranged, the eccentric light-transmitting plate 92 is eccentrically arranged with the plate body 91, and the two eccentric light-transmitting plates 92 on the two eccentric measuring plates 9 are oriented in opposite directions, so that when the light-transmitting rod 801 and the deflection measuring hole 802 are offset in different directions, there will be obvious differences in the data obtained by the upper laser rangefinder 81, and the distances between the center points of the two eccentric light-transmitting plates 92 and the central axis of the transposition rotary sleeve 703 are the same.

[0027] It is worth noting that in the specific implementation, Fig.11 as well as Fig.12 The upper and lower positions of the two eccentric measuring plates 9 shown in the figure are not limited and can be selectively set according to actual needs.

[0028] In summary, this solution can realize the automated operation of ceramic core injection, effectively reduce the dependence on manual labor, reduce the impact of human factors on product quality, and improve production efficiency. The entire molding process is integrated on one device, which greatly reduces the footprint and reduces cost investment compared to the cooperation of multiple devices in the prior art. At the same time, through the setting of the quick-change unit, different injection molds can be automatically and quickly replaced. Compared with the manual removal of the old mold and the installation of the new mold in the prior art, the downtime for mold change is greatly reduced, and the impact of mold change on production efficiency is effectively reduced. At the same time, with the setting of the deviation measuring unit, real-time monitoring can be carried out during the mold change process, and the position can be self-fine-tuned, thereby effectively ensuring the mold change efficiency, further reducing downtime and improving production efficiency.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
