Description

Technical Field

[0001] The present invention relates to the technical field of injection devices, and more particularly to an injection device for the production of automotive rearview mirrors. Background Art

[0002] An injection device is one of the molding devices used for manufacturing automotive rearview mirrors. Among them, the common injection device mainly consists of a base, an inverted U-shaped hanging beam, an injection crucible structure, an injection punch, a diversion tube, a support buffer base, a lower pressing plate, and a mold holder, etc. The production process of the injection device for automotive rearview mirrors is as follows: Pour the molten metal into the injection crucible structure, and adjust the telescopic rod to make the upper pressing plate body press tightly against the lower pressing plate, and at the same time fix the automotive rearview mirror mold well; Control the operation of the stamping machine, drive the stamping connecting rod and the injection punch to descend, and spray the molten metal into the mold through the injection chamber and the diversion tube; After the injection is completed, start the cooling pipeline, and make the coolant enter the cooling coil through the water injection and cooling connecting pipe for cooling; After the finished product is cooled, loosen the telescopic rod and take out the finished product;

[0003] During the production of automotive rearview mirrors by the injection device, we found that the connection ends of the diversion tube with the stamping assembly and the production mold are extremely prone to falling off or loosening and other phenomena. The main reasons for this problem are: First, the connecting parts of the diversion tube become loose: Due to the influence of vibration and impact during long-term use, wear is extremely likely to occur between the components; Second, external factors: If excessive force or improper operation methods are used during the operation process, it may cause damage or loosening to the diversion tube; When the above phenomena occur, the following impacts will appear: First, the flow control is affected: The loosening of the diversion tube may cause changes in its internal channel, thereby affecting the flow rate passing through it; Second, the pressure loss increases: When the diversion tube is loose, the fluid may encounter additional resistance when passing through, resulting in an increase in pressure loss; Third, the leakage risk increases. The loosening of the diversion tube may cause gaps at the connection, thereby increasing the risk of leakage; The above impacts cause the automotive rearview mirror to be unable to be produced normally, and thus lead to certain economic losses;

[0004] Therefore, we now urgently need an injection device for the production of automotive rearview mirrors to solve the above-mentioned technical problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an injection device for the production of automotive rearview mirrors to solve the problems existing in the above background art.

[0006] The present invention provides the following technical solutions: An injection device for the production of automotive rearview mirrors, characterized in that it includes:

[0007] An injection device, wherein a control system is installed inside the injection device;

[0008] A mold mechanism for assisting in the casting and molding of automotive rearview mirrors. The mold mechanism is installed on the side of the upper surface of the injection device, and a protective shell is installed at the casting end of the mold mechanism.

[0009] A power supply device for providing the power required for the production of automotive rearview mirrors. The power supply device is installed on the other side of the upper surface of the injection device, and a shot sleeve is installed at a position on the side of the injection device close to the power supply device for storing the raw materials required for the production of automotive rearview mirrors.

[0010] One end of the protective shell close to the power supply device is installed with an air pump. The output end of the air pump is installed with a diversion pipe, which is placed inside the protective shell, and the geometric center point of the diversion pipe and the geometric center point of the protective shell are on the same straight line. A temperature sensing device is installed on the inner wall of the protective shell, and the temperature sensing device collects the temperature data generated on the surface of the diversion pipe and transmits it to the control system for monitoring the temperature change of the raw materials inside the diversion pipe.

[0011] Furthermore, a ventilation groove is opened on the inner wall of the protective shell. The ventilation groove extends along the inner wall of the protective shell and presents a threaded shape. A first delivery pipe is installed through the side of the protective shell close to the air pump. The end of the first delivery pipe away from the protective shell is installed with an air pump, and the air pump is installed at a position on the outer wall of the power supply device close to the protective shell. The output end of the air pump is installed with a first input pipe, and a temperature control device is installed inside the air pump for cooling the compressed air conveyed inside the air pump.

[0012] Furthermore, the end of the first delivery pipe away from the air pump is installed with a Y-shaped delivery pipe. The Y-shaped delivery pipe has two outlet ends. One outlet end of the Y-shaped delivery pipe is installed inside one end of the ventilation groove for the input of cooling air, and a trachea is installed inside the other end of the ventilation groove for the discharge of cooling air.

[0013] A heating plate is installed on the inner wall of the protective shell for adjusting the temperature environment outside the diversion pipe.

[0014] Furthermore, an annular plate is installed on the outer wall at the middle position of the diversion pipe. The other air outlet end of the Y-shaped delivery pipe is installed through the inside of the side of the annular plate. Two auxiliary partition plates are installed on the inner wall of the annular plate near the Y-shaped delivery pipe. The two auxiliary partition plates are perpendicular to the inner walls of the top and bottom of the annular plate and form an independent sealed storage space with the inner wall of the annular plate. A main partition plate is installed on the inner wall at the middle position of the annular plate. Both ends of the main partition plate are installed on the sides of the two auxiliary partition plates. Among them, the annular plate, the main partition plate and the auxiliary partition plates form two independent delivery cabins. First electromagnetic valves are installed on the inner walls of the two auxiliary partition plates. The positions of the first electromagnetic valves installed on the surfaces of the two auxiliary partition plates are opposite, so that the compressed air in the sealed storage space can be respectively input into the two delivery cabins through the two first electromagnetic valves.

[0015] Furthermore, auxiliary hollow columns are installed through the inner walls of the top and bottom of the annular plate. A hollow support column is movably sleeved in the middle position of the auxiliary hollow column. The auxiliary hollow column can move parallelly inside the inner wall of the hollow support column. First springs are vertically installed on the inner walls at both ends of the hollow support column. One end of the auxiliary hollow column away from the annular plate is installed with a main board body. An electromagnetic control valve is installed in the middle area of the auxiliary hollow column near the main board body. An input groove is opened on the inner wall of the main board body near the electromagnetic control valve. The geometric center points of the input groove and the electromagnetic control valve are on the same straight line. A pressure sensor is installed inside the hollow support column for detecting the pressure data inside the auxiliary hollow column and the hollow support column and transmitting it to the control system.

[0016] Furthermore, a limiting plate is sleeved on the outer wall of the main board body. A second spring is vertically installed on the inner side surface of the limiting plate close to the main board body. One end of the second spring away from the auxiliary hollow column is vertically installed on the outer side surface of the main board body. Telescopic plates are installed on the inner walls on both sides of the limiting plate away from the main board body. An auxiliary countersunk head groove is opened on the inner side surface of the telescopic plate close to the main board body. A torsion spring plate is installed on the inner wall of the countersunk head groove.

[0017] Furthermore, the control system includes a temperature control unit and a temporary processing unit. The temperature control unit inputs the optimal forming temperature range of raw material delivery manually. The temperature control unit compares the real-time temperature data with the optimal forming temperature range to judge whether the external temperature of the diversion pipe is conducive to the forming and production of the product.

[0018] The temporary processing unit simulates the simulated pressure data generated by the pressure sensor when the diversion pipe, the injection device and the air pump are in a completely installed state, and integrates the simulated pressure data to form a first threshold range. The temporary processing unit compares the real-time pressure data with the first threshold range. When the real-time pressure data is not within the first threshold range, it can be judged that there is an incomplete connection at a certain installation place between the diversion pipe, the injection device and the air pump.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The present invention collects the pressure data inside the auxiliary hollow column and the hollow support column through a pneumatic sensor. The control system analyzes the collected pressure data. When the collected pressure data is not within the optimal forming temperature range, the control system determines that there is an incomplete connection between the diversion pipe and the injection device and the outer wall of the air pump, and sends a warning message to the staff through the control system to remind the staff to arrive at the scene for maintenance.

[0021] 2. When the control system of the present invention determines that there is an incomplete connection between the diversion pipe and the injection device and the outer wall of the air pump, the air pump inputs a stable working current to generate an adsorption force, and inputs it into the sealed storage space of the annular plate through the first delivery pipe and the other air outlet end of the Y-shaped delivery pipe. At this time, a stable working current is input to the corresponding first solenoid valve to control the adsorption force to be input into the corresponding delivery chamber and transported into the corresponding auxiliary hollow column and hollow support column, driving the corresponding auxiliary hollow column to slide on the inner wall of the hollow support column, thereby reducing the overall length data of the corresponding auxiliary hollow column and hollow support column, and controlling the annular plate to drive the diversion pipe to move towards the end with incomplete connection of the diversion pipe, so as to provide a temporary limiting and fixing effect at this place.

[0033] One end of the protective shell 5 close to the power supply device 3 is installed with an air pump 501. The output end of the air pump 501 is installed with a diversion pipe 507. The diversion pipe 507 is placed inside the protective shell 5, and the geometric center point of the diversion pipe 507 and the geometric center point of the protective shell 5 are on the same straight line. A temperature sensing device is installed on the inner wall of the protective shell 5. The temperature sensing device collects the temperature data generated on the surface of the diversion pipe 507 and transmits it to the control system for monitoring the temperature change of the raw materials inside the diversion pipe 507.

[0034] In the embodiments of the present application, the specific working process of this part of the embodiments is as follows: Pour the production raw materials of the automotive rearview mirror into the injection crucible 4. Under the action of the power supply device 3, transport the production raw materials inside the injection crucible 4 to the air pump 501, and then transmit them to the mold mechanism 2 through the protective shell 5 for product forming operation. After the product is formed, the cooling mechanism inside the mold mechanism 2 inputs a stable working current to cool the formed product. After the product is cooled, the preliminary processing of the automotive rearview mirror can be completed.

[0035] Referring Figures 1 to 4 As shown, the present invention provides an injection device for the production of automotive rearview mirrors. An air vent groove 506 is provided on the inner wall of the protective shell 5. The air vent groove 506 extends along the inner wall of the protective shell 5 and presents a threaded shape. A first delivery pipe 502 is installed through the side of the protective shell 5 near the air pump 501. One end of the first delivery pipe 502 away from the protective shell 5 is installed with an air pump 501. The air pump 501 is installed on the outer wall of the power supply device 3 near the protective shell 5. The output end of the air pump 501 is installed with a first input pipe 503. A temperature control device is installed inside the air pump 501 for cooling the compressed air conveyed inside the air pump 501;

[0036] One end of the first delivery pipe 502 away from the air pump 501 is installed with a Y-shaped delivery pipe 505. The Y-shaped delivery pipe 505 has two outlet ends. One outlet end of the Y-shaped delivery pipe 505 is installed inside one end of the air vent groove 506 for inputting cooling air. A trachea 504 is installed inside the other end of the air vent groove 506 for discharging cooling air;

[0039] The specific working process of this part of the application embodiment is as follows: The temperature sensing device collects the temperature data generated on the surface of the diversion pipe 507 and transmits it to the control system. The control system determines whether the external temperature of the diversion pipe 507 is within the optimal forming temperature range of the raw material. When the external temperature of the diversion pipe 507 is higher than the optimal forming temperature range, the air pump 501 and the temperature control device input a stable working current, thereby generating cooled compressed air, which is input into the ventilation groove 506 through a group of air outlet ends of the first conveying pipe 502 and the Y-shaped conveying pipe 505. The cooled compressed air circulates inside the ventilation groove 506, thereby achieving the effect of reducing the external temperature of the diversion pipe 507. The cooling temperature inside the ventilation groove 506 is then discharged through the air pipe 504 to ensure that the compressed air inside the ventilation groove 506 can continuously circulate and continuously cool the external temperature of the diversion pipe 507. When the control system determines that the external temperature of the diversion pipe 507 is lower than the optimal forming temperature range, the heating plate 508 inputs a stable working current to raise the external temperature of the diversion pipe 507 to ensure that the production raw material inside the diversion pipe 507 is in the optimal state and further ensure the production quality of the product.

[0040] Referring to Figures 1 to 6 As shown, the present invention provides an injection device for automobile rearview mirror production. An annular plate 6 is installed on the outer wall at the middle position of the diversion pipe 507. The other group of air outlet ends of the Y-shaped conveying pipe 505 are installed through the inside of the side of the annular plate 6. Two auxiliary partition plates 603 are installed on the inner wall of the annular plate 6 near the Y-shaped conveying pipe 505. The two auxiliary partition plates 603 are perpendicular to the inner walls of the top and bottom of the annular plate 6 and form an independent sealed storage space with the inner wall of the annular plate 6. A main partition plate 61 is installed on the inner wall at the middle position of the annular plate 6. Both ends of the main partition plate 61 are installed on the sides of the two auxiliary partition plates 603. Among them, the annular plate 6, the main partition plate 61, and the auxiliary partition plates 603 form two independent conveying cabins. First solenoid valves 604 are installed on the inner walls of the two auxiliary partition plates 603. The positions of the first solenoid valves 604 installed on the surfaces of the two auxiliary partition plates 603 are opposite, so that the compressed air in the sealed storage space can be respectively input into the two conveying cabins through the two first solenoid valves 604;

[0041] The inner walls of the top and bottom of the annular plate 6 are both penetrated and installed with auxiliary hollow columns 601. A hollow support column 602 is movably sleeved in the middle position of the auxiliary hollow column 601. The auxiliary hollow column 601 can move parallelly inside the inner wall of the hollow support column 602. First springs 605 are vertically installed on the inner walls at both ends of the hollow support column 602. One end of the auxiliary hollow column 601 away from the annular plate 6 is installed with a main board body 606. An electric control valve is installed in the middle area of the auxiliary hollow column 601 close to the main board body 606. An input groove 608 is opened on the inner wall of the main board body 606 close to the electric control valve. The geometric center point of the input groove 608 and the geometric center point of the electric control valve are on the same straight line. A pressure sensor is installed inside the hollow support column 602 for detecting the pressure data inside the auxiliary hollow column 601 and the hollow support column 602 and transmitting it to the control system;

[0042] A limiting plate 607 is sleeved on the outer wall of the main board body 606. A second spring 611 is vertically installed on the inner side surface of the limiting plate 607 close to the main board body 606. One end of the second spring 611 away from the auxiliary hollow column 601 is vertically installed on the outer side surface of the main board body 606. Telescopic plates 609 are installed on the inner walls on both sides of the limiting plate 607 away from the main board body 606. An auxiliary countersunk head groove is opened on the inner side surface of the telescopic plate 609 close to the main board body 606. A torsion spring plate 610 is installed on the inner wall of the countersunk head groove.

[0043] In the embodiment of the present application, the number of the limiting plates 607 is two groups. The two groups of limiting plates 607 are respectively installed on the outer walls of the injection device 1 and the air pump 501. Main countersunk head grooves adapted to the two groups of limiting plates 607 are opened in the installation outer wall areas for fixing the two groups of limiting plates 607.

[0044] The specific working process of this part of the application embodiment is as follows: When both ends of the diversion pipe 507 are installed on the outer walls of the injection device 1 and the air pump 501 respectively, the air pump 501 inputs a stable working current to generate compressed air, which is input into the sealed storage space of the annular plate 6 through the first delivery pipe 502 and the other air outlet end of the Y-shaped delivery pipe 505. The two groups of first solenoid valves 604 input a stable working current, and the compressed air in the sealed storage space is respectively input into the two delivery cabins and then conveyed into the two auxiliary hollow columns 601 and hollow struts 602, driving the auxiliary hollow column 601 to slide on the inner wall of the hollow strut 602, thereby increasing the overall length data of the auxiliary hollow column 601 and the hollow strut 602. When the overall length of the auxiliary hollow column 601 and the hollow strut 602 changes, the two limit plates 607 are driven to move into the corresponding main countersunk grooves. At the same time, the two electromagnetic control valves input a stable current, and the compressed air inside the auxiliary hollow column 601 enters the inside of the limit plate 607 through the input groove 608, driving the limit plate 607 to move into the main countersunk groove. When the pressure value inside the limit plate 607 reaches a certain value, the torsion spring plate 610 is driven to rotate, and the compressed air inside the limit plate 607 is input into the inside of the telescopic plate 609, driving the length of the telescopic plate 609 to increase, and then clamping into the inner wall of the main countersunk groove, so that the limit plate 607 is fixed and limited in the main countersunk groove;

[0045] When there is an incomplete connection between the diversion pipe 507 and the outer walls of the injection device 1 and the air pump 501, the length of the corresponding hollow strut 602 changes, which in turn causes the pressure data collected by the air pressure sensor inside the auxiliary hollow column 601 and the hollow strut 602 to change. Through the analysis of the change in the pressure data by the control system, it is further determined that there is an incomplete connection between the diversion pipe 507 and the outer walls of the injection device 1 and the air pump 501, and a warning message is sent to the staff through the control system to remind the staff to arrive at the scene for maintenance;

[0046] When the control system determines that there is an incomplete connection between the diversion pipe 507 and the outer walls of the injection device 1 and the air pump 501, the air pump 501 inputs a stable working current to generate an adsorption force, which is input into the sealed storage space of the annular plate 6 through the first delivery pipe 502 and the other air outlet end of the Y-shaped delivery pipe 505. At this time, the corresponding first solenoid valve 604 inputs a stable working current to control the adsorption force to be input into the corresponding delivery cabin and then conveyed into the corresponding auxiliary hollow column 601 and hollow strut 602, driving the corresponding auxiliary hollow column 601 to slide on the inner wall of the hollow strut 602, thereby reducing the overall length data of the corresponding auxiliary hollow column 601 and hollow strut 602, and controlling the annular plate 6 to drive the diversion pipe 507 to move towards the end with incomplete connection of the diversion pipe 507, so as to provide a temporary limiting and fixing effect at this place.

[0047] Refer to Figures 1 to 6As shown, the present invention provides an injection device for the production of automotive rearview mirrors. The control system includes a temperature control unit and a temporary processing unit. The temperature control unit inputs the optimal molding temperature range for raw material transportation manually, and compares the real-time temperature data with the optimal molding temperature range to determine whether the external temperature of the diversion tube 507 is conducive to the molding and production of the product;

[0048] The temporary processing unit simulates the analog pressure data generated by the air pressure sensor when the diversion tube 507, the injection device 1, and the air pump 501 are in a fully installed state, and integrates the analog pressure data to form a first threshold range. The temporary processing unit compares the real-time pressure data with the first threshold range. When the real-time pressure data is not within the first threshold range, it can be determined that there is an incomplete connection at a certain installation point between the diversion tube 507, the injection device 1, and the air pump 501.

[0049] The specific working process of this application is as follows:

[0050] Product production process: Pour the raw materials for the production of automotive rearview mirrors into the injection crucible 4. Under the action of the power supply device 3, the production raw materials in the injection crucible 4 are transported into the air pump 501, and then transmitted to the mold mechanism 2 through the protective shell 5 for product molding operations. After the product is molded, the cooling mechanism inside the mold mechanism 2 inputs a stable working current to cool the molded product. After the product is cooled, the preliminary processing of the automotive rearview mirror can be completed;

[0051] Temperature detection and adjustment: The temperature sensing device collects the temperature data generated on the surface of the diversion tube 507 and transmits it to the control system. The control system determines whether the external temperature of the diversion tube 507 is within the optimal molding temperature range of the raw materials. If the external temperature of the diversion tube 507 is higher than the optimal molding temperature range, the air pump 501 and the temperature control device input a stable working current to generate cooled compressed air, which is input into the ventilation groove 506 through a set of air outlet ends of the first delivery pipe 502 and the Y-shaped delivery pipe 505. The cooled compressed air circulates inside the ventilation groove 506 to achieve the effect of reducing the external temperature of the diversion tube 507. The cooling temperature inside the ventilation groove 506 is then discharged through the air pipe 504 to ensure that the compressed air inside the ventilation groove 506 can continue to circulate and continuously cool the external temperature of the diversion tube 507. When the control system determines that the external temperature of the diversion tube 507 is lower than the optimal molding temperature range, the heating plate 508 inputs a stable working current to increase the external temperature of the diversion tube 507 to ensure that the production raw materials inside the diversion tube 507 are in an optimal state and further ensure the production quality of the product;

[0052] Installation status detection: When both ends of the diversion pipe 507 are installed on the outer walls of the injection device 1 and the air pump 501 respectively, the air pump 501 inputs a stable working current to generate compressed air, which is input into the sealed storage space of the annular plate 6 through the first delivery pipe 502 and the other set of air outlet ends of the Y-shaped delivery pipe 505. The two first solenoid valves 604 input a stable working current to respectively input the compressed air in the sealed storage space into the two delivery cabins, and then transport it into the two auxiliary hollow columns 601 and hollow struts 602, driving the auxiliary hollow column 601 to slide on the inner wall of the hollow strut 602, thereby increasing the overall length data of the auxiliary hollow column 601 and the hollow strut 602. When the overall length of the auxiliary hollow column 601 and the hollow strut 602 changes, it drives the two limit plates 607 to move into the corresponding main countersunk grooves. At the same time, the two electromagnetic control valves input a stable current, and the compressed air inside the auxiliary hollow column 601 enters the inside of the limit plate 607 through the input groove 608, driving the limit plate 607 to move into the inside of the main countersunk groove. When the pressure value inside the limit plate 607 reaches a certain value, it drives the torsion spring plate 610 to be in a rotating state, and the compressed air inside the limit plate 607 is input into the inside of the telescopic plate 609, driving the length of the telescopic plate 609 to increase, and then clamping it into the inner wall of the main countersunk groove, so as to fix and limit the limit plate 607 in the main countersunk groove;

[0053] When there is an incomplete connection between the diversion pipe 507 and the outer walls of the injection device 1 and the air pump 501, the length of the corresponding hollow strut 602 changes, which in turn causes the pressure data collected by the air pressure sensor inside the auxiliary hollow column 601 and the hollow strut 602 to change. Through the analysis of the change in the pressure data by the control system, it is determined that there is an incomplete connection between the diversion pipe 507 and the outer walls of the injection device 1 and the air pump 501, and a warning message is sent to the staff through the control system to remind the staff to arrive at the scene for maintenance;

[0054] When the control system determines that there is an incomplete connection between the diversion pipe 507 and the outer walls of the injection device 1 and the air pump 501, the air pump 501 inputs a stable working current to generate an adsorption force, which is input into the sealed storage space of the annular plate 6 through the first delivery pipe 502 and the other set of air outlet ends of the Y-shaped delivery pipe 505. At this time, the corresponding first solenoid valve 604 inputs a stable working current to control the adsorption force to be input into the corresponding delivery cabin, and then transport it into the corresponding auxiliary hollow column 601 and hollow strut 602, driving the corresponding auxiliary hollow column 601 to slide on the inner wall of the hollow strut 602, thereby reducing the overall length data of the corresponding auxiliary hollow column 601 and the hollow strut 602, and controlling the annular plate 6 to drive the diversion pipe 507 to move towards the end with incomplete connection of the diversion pipe 507, so as to provide a temporary limiting and fixing effect at this place.
