Description

Technical Field

[0001] The invention relates to the technical field of injection molding of vehicle chargers, in particular to a synchronous processing mold device for upper and lower shells of a vehicle charger. Background Art

[0002] The car charger is an accessory that is used to charge digital products anytime and anywhere with the car power supply. It is commonly used for car battery power supply and is widely used in the field of lithium battery charging of various portable and handheld devices. The shell structure of the car charger is mainly composed of two shells, and the shell of the car charger is usually produced by injection molding.

[0003] In the patent document with the announcement number CN206242391U, a synchronous processing mold for the upper and lower shells of the vehicle charger is proposed. The mold includes an upper mold and a lower mold. The upper mold includes a panel and an upper mold plate. An upper mold core is provided in the middle position inside the upper mold plate. The lower mold includes a lower mold plate, a pad, an ejector plate, an ejector stripping plate and a bottom plate. The mold structure is used to perform one-time injection molding of the upper and lower shells of the vehicle charger.

[0004] Although the mold structure can be used to mold the upper and lower shells of the on-board charger at one time, since the upper and lower shells of the on-board charger are molded at one time in the same mold, not only will there be more heat in the mold during injection molding, but it will also cause the temperature inside the mold to be too concentrated, resulting in a significant reduction in the cooling speed of the mold, which will greatly prolong the cooling molding time of the upper and lower shells of the on-board charger and reduce the processing efficiency of the upper and lower shells of the on-board charger. To this end, we propose a synchronous processing mold device for the upper and lower shells of the on-board charger. Summary of the invention

[0008] The descaling assembly includes a positioning shaft arranged inside the male mold assembly, a paddle movably arranged on the side of the positioning shaft, a positioning ring group fixedly arranged on the outer edge of the paddle, and a scraper bar assembly fixedly arranged on the outer side of the positioning ring group.

[0010] Preferably, a positioning sleeve is fixedly installed in the middle of the interior of the positioning tube via three positioning plates, the three positioning plates are evenly spaced apart inside the positioning tube, and the positioning shaft and the positioning sleeve are fixedly connected.

[0011] Preferably, two blades of the same shape are movably arranged on the side of the positioning shaft, and the two blades are both located inside the mold. A corresponding positioning ring group is arranged on the outer edge of each blade, and three scraper strip assemblies are arranged, and each scraper strip assembly is connected to two positioning ring groups.

[0012] Preferably, the cooling component includes a water tank, a water pump, a first solenoid valve and a second solenoid valve. The water tank is arranged on one side of the workbench, and the water pump is fixedly arranged on the upper side of the water tank. The water inlet end of the water pump is connected to the water tank through a water inlet pipe, and the water outlet end of the water pump is connected to the first solenoid valve through a water outlet pipe. A first three-way pipe is fixedly installed at the water outlet end of the first solenoid valve, and the two water outlet ends of the first three-way pipe are respectively connected to a positioning pipe, and the water outlet ends of the two connecting pipes are connected to a second three-way pipe, and the water outlet end of the second three-way pipe is connected to the second solenoid valve, and the water outlet end of the second solenoid valve is connected to the water tank through a return pipe.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention uses a cooling assembly to inject water into the interior of the male mold assembly and keeps the water pressure inside the male mold assembly the same as the pressure required for mold cavity injection, thereby preventing the male mold assembly from being deformed due to the high pressure in the mold cavity, thereby preventing the size of the processed vehicle charger shell from being deformed.

[0019] 2. In the present invention, the male mold assembly is a metal material with good thermal conductivity. By using a cooling assembly to inject water into the two male mold assemblies respectively, the heat in the mold cavity is absorbed through the tube wall of each male mold assembly, ensuring that the contact distance between the cooling water and the heat source is shorter and the contact surface is larger. In this way, the injection-molded vehicle charger shell is cooled, which can accelerate the cooling of each vehicle charger shell, greatly improve the cooling efficiency of each vehicle charger shell, and improve the production and processing efficiency of the vehicle charger shell, solving the problem of low production efficiency caused by low mold cooling efficiency after the vehicle charger shell is formed in the existing technology of simultaneously injecting two shells of the vehicle charger.

[0020] 3. The present invention uses water flow to drive the descaling component to remove the scale inside the male mold component, preventing the cooling effect of the cooling component from being reduced due to scaling inside the male mold component. The device uses the descaling component to remove the scale inside the male mold component when the car charger shell is cooled, forming a working mode of cooling and descaling, which will not affect the injection molding work of the car charger shell, and thus will not reduce the injection molding production efficiency of the car charger shell.

[0021] 4. In the present invention, when descaling the male mold assembly, water flows into the male mold assembly to push the blade to rotate on the positioning shaft, and the blade drives the scraper assembly to rotate synchronously through the positioning ring assembly. The scraper assembly scrapes the scale attached to the inner wall of the male mold assembly to prevent the scale from accumulating on the inner wall of the male mold assembly, which will cause the cooling efficiency of the cooling assembly in the mold cavity to decrease. The connection between the positioning ring assembly and the blade facilitates the installation of the positioning ring assembly, and the connection between the scraper assembly and the positioning ring assembly facilitates the installation of the scraper assembly, making the installation of the scraper assembly on the blade more stable.

[0022] 5. In the descaling stage of the present invention, the vibration of the vibration motor causes the inner walls of the scraper bar assembly and the punch assembly to vibrate, which enables the scraper bar assembly to produce disorderly oscillations and impacts on the inner wall of the punch assembly, making it convenient for the scraper bar assembly to break and remove the stubborn scale attached to the inner wall of the punch assembly, avoiding the stubborn scale attached to the inner wall of the punch assembly from obstructing the scraper bar assembly, causing the rotation of the blades, the positioning ring group and the scraper bar assembly to be affected, thereby ensuring the normal rotation of the blades, the positioning ring group and the scraper bar assembly, and always having a good descaling effect.

[0023] 6. The present invention can ensure more uniform and sufficient filling of raw materials when raw materials are injected into the mold cavity through the oscillation of the vibration motor, thereby preventing the problem of insufficient filling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0039] See also Figure 1 - Fig.11 As shown, a mold device for synchronously processing the upper and lower shells of a vehicle charger, a mold device for synchronously processing the upper and lower shells of a vehicle charger, includes a workbench 1, an outer mold 2 and an inner mold 3 are arranged above the workbench 1, two outer molds 2 are arranged, the inner mold 3 is located at the center of the two outer molds 2, side grooves 4 are respectively opened on both sides of the inner mold 3, and a punch assembly 5 is fixedly arranged inside each side groove 4, and a mold cavity 6 is formed between the punch assembly 5, the inner mold 3 and the outer mold 2, and also includes a cooling assembly 7 and a descaling assembly 8. The cooling assembly 7 cools the mold cavity 6 by injecting cooling water into the punch assembly 5; the cooling assembly 7 is arranged on both sides of the workbench 1.

[0040] Based on this device, hydraulic components 20 for driving the two outer molds 2 to move are respectively arranged on both sides above the workbench 1, and the inner mold 3 is fixedly installed above the workbench 1. Four limiting shafts 21 are fixedly arranged on the workbench 1 and the inner mold 3. The limiting shafts 21 respectively penetrate each outer mold 2. The hydraulic component 20 drives the outer mold 2 to move toward the inner mold 3 for mold closing. When the mold is closed, the gap between the punch component 5, the inner mold 3 and the outer mold 2 is the mold cavity 6 for the injection molding of the vehicle charger shell.

[0041] During the injection molding stage of the on-board charger shell in the mold cavity 6, a certain pressure needs to be maintained in the mold cavity 6 to expel the air in the mold cavity. In order to prevent the male mold component 5 from being deformed during injection molding, before injecting the raw material into the mold cavity 6, the cooling component 7 is used to inject water into the male mold component 5, and the water pressure inside the male mold component 5 is kept the same as the pressure required for injection molding of the mold cavity 6, so as to prevent the male mold component 5 from being deformed due to the high pressure in the mold cavity 6, resulting in the deformation of the size of the processed on-board charger shell.

[0042] The male mold component 5 is a metal material with good thermal conductivity. By using the cooling component 7 to inject water into the two male mold components 5 respectively, the heat in the mold cavity 6 is absorbed through the tube wall of each male mold component 5, ensuring that the contact distance between the cooling water and the heat source is shorter and the contact surface is larger, so as to cool down the injection-molded vehicle charger shell, which can speed up the cooling of each vehicle charger shell, greatly improve the cooling efficiency of each vehicle charger shell, and improve the production and processing efficiency of the vehicle charger shell, and solve the problem of low production efficiency caused by low mold cooling efficiency after the vehicle charger shell is formed in the existing technology of simultaneous injection molding of two vehicle charger shells. Since the mold cavity 6 is a high-temperature environment, heat will enter the interior of the male mold component 5 during injection molding, causing the water temperature inside the male mold component 5 to rise, so that scaling will occur inside the male mold component 5, so it is necessary to remove scale inside the male mold component 5.

[0043] In the cooling stage of the on-board charger shell injection-molded in the mold cavity 6, the cooling component 7 is used to inject cold water into the male mold component 5 to cool the on-board charger shell molded in the mold cavity 6. In this stage, the descaling component 8 is driven by water flow to remove the scale inside the male mold component 5 to prevent the cooling effect of the cooling component 7 from being reduced due to scaling inside the male mold component 5. The device uses the descaling component 8 to remove the scale inside the male mold component 5 when the on-board charger shell is cooled, forming a working mode of descaling while cooling, which will not affect the injection molding work of the on-board charger shell, and therefore will not reduce the injection molding production efficiency of the on-board charger shell.

[0044] The descaling assembly 8 includes a positioning shaft 81 arranged inside the male mold assembly 5, a paddle 82 movably arranged on the side of the positioning shaft 81, a positioning ring group 83 fixedly arranged on the outer edge of the paddle 82, and a scraper assembly 84 fixedly arranged on the outer side of the positioning ring group 83. The outer edge of the scraper assembly 84 is in contact with the inner wall of the male mold assembly 5, and a vibration motor 9 is arranged inside the inner mold 3.

[0045] When removing scale from the male mold assembly 5, water flows into the male mold assembly 5 to push the paddle 82 to rotate on the positioning shaft 81, and the paddle 82 rotates synchronously with the scraper assembly 84 through the positioning ring assembly 83. The scraper assembly 84 scrapes off the scale attached to the inner wall of the male mold assembly 5 to prevent the scale from accumulating on the inner wall of the male mold assembly 5, which will cause the cooling efficiency of the cooling assembly 7 in the mold cavity 6 to decrease. The connection between the positioning ring assembly 83 and the paddle 82 facilitates the installation of the positioning ring assembly 83, and the connection between the scraper assembly 84 and the positioning ring assembly 83 facilitates the installation of the scraper assembly 84, making the installation of the scraper assembly 84 on the paddle 82 more stable.

[0046] During the descaling stage, the vibration of the vibration motor 9 causes the scraper assembly 84 and the inner wall of the punch assembly 5 to vibrate, which enables the scraper assembly 84 to produce disorderly oscillations and impacts on the inner wall of the punch assembly 5, making it convenient for the scraper assembly 84 to break and remove the stubborn scale attached to the inner wall of the punch assembly 5, thereby preventing the stubborn scale attached to the inner wall of the punch assembly 5 from obstructing the scraper assembly 84 and affecting the rotation of the paddle 82, the positioning ring group 83 and the scraper assembly 84, thereby ensuring the normal rotation of the paddle 82, the positioning ring group 83 and the scraper assembly 84 and always having a good descaling effect.

[0047] The vibration motor 9 works during the injection molding stage of the on-board charger housing. Through the oscillation of the vibration motor 9, when the raw material is injected into the mold cavity 6, it can ensure that the filling of the raw material is more uniform and sufficient, thereby preventing the problem of insufficient filling.

[0048] Based on the device, during the injection molding process of the upper and lower shells of the vehicle charger housing, the upper and lower shells of the vehicle charger housing are processed synchronously under the same conditions, so that the upper and lower shells of the vehicle charger housing produced have better adaptability.

[0049] The male mold assembly 5 includes a resist mold 51, a positioning tube 52 and a connecting tube 53 fixedly arranged inside the side groove 4. One end of the positioning tube 52 is inserted into one end of the resist mold 51, and the connecting tube 53 is fixedly connected to the other end of the resist mold 51.

[0050] Based on this design, the male mold assembly 5 is configured as three structures, namely, the mold 51, the positioning tube 52 and the connecting tube 53, so as to facilitate the installation of the scraper assembly 84 inside the male mold assembly 5. One end of the connecting tube 53 is inserted into one end of the mold 51 to support the inner wall of the port of the mold 51, thereby improving the pressure resistance of the mold 51 and preventing the mold 51 from being deformed due to excessive pressure in the mold cavity 6.

[0051] A positioning sleeve 11 is fixedly installed in the middle of the positioning tube 52 through three positioning plates 10 . The three positioning plates 10 are evenly spaced and distributed inside the positioning tube 52 . The positioning shaft 81 and the positioning sleeve 11 are fixedly connected.

[0052] Based on the present design, one end of the positioning plate 10 is a knife-shaped structure to reduce the resistance to the water flow. The positioning plate 10 and the positioning sleeve 11 are arranged to facilitate the positioning shaft 81 to be fixedly installed in the middle of the inner part of the positioning tube 52.

[0053] Among them, two paddles 82 of the same shape are movably set on the side of the positioning shaft 81, and the two paddles 82 are both located inside the mold 51. The outer edge of each paddle 82 is provided with a corresponding positioning ring group 83, and three scraper bar assemblies 84 are provided, and each scraper bar assembly 84 is connected to two positioning ring groups 83.

[0054] Based on this design, two paddles 82 are arranged inside the anti-mold 51, and each paddle 82 is connected to the scraper assembly 84, so that the installation of the scraper assembly 84 is more stable. When the scraper assembly 84 is driven to rotate by the structure of the paddle 82 and the positioning ring group 83, the scraper assembly 84 has better conformability and is not easy to bend.

[0055] Among them, the cooling component 7 includes a water tank 71, a water pump 72, a first solenoid valve 73 and a second solenoid valve 74. The water tank 71 is arranged on one side of the workbench 1, and the water pump 72 is fixedly arranged on the upper side of the water tank 71. The water inlet end of the water pump 72 is connected to the water tank 71 through the water inlet pipe 12, and the water outlet end of the water pump 72 is connected to the first solenoid valve 73 through the water outlet pipe 13. The water outlet end of the first solenoid valve 73 is fixedly installed with a first three-way pipe 14, and the two water outlet ends of the first three-way pipe 14 are respectively connected to a positioning pipe 52, and the water outlet ends of the two connecting pipes 53 are connected to the second three-way pipe 15, and the water outlet end of the second three-way pipe 15 is connected to the second solenoid valve 74. The water outlet end of the second solenoid valve 74 is connected to the water tank 71 through the return pipe 22.

[0056] Based on this design, during the injection molding stage of the vehicle charger shell in the mold cavity 6, the water pump 72 is first used to fill the inside of the male mold assembly 5 with water, so that the water pressure inside the male mold assembly 5 is the same as the pressure required for injection molding of the mold cavity 6, and then the first solenoid valve 73 and the second solenoid valve 74 are closed, and the high temperature of the molten plastic in the mold cavity 6 is transmitted to the male mold assembly 5, so that when the pressure inside the male mold assembly 5 increases, the second solenoid valve 74 is opened to discharge a small amount of water, so as to always keep the water pressure inside the male mold assembly 5 the same as the pressure required for injection molding of the mold cavity 6, and ensure that the male mold assembly 5 will not deform under the high pressure in the mold cavity 6. During the cooling molding stage of the vehicle charger shell in the mold cavity 6, the first solenoid valve 73 and the second solenoid valve 74 are opened, and the water pump 72 continuously injects cold water into the male mold assembly 5 to cool the molded vehicle charger shell. A filtering structure is provided in the water storage tank 71, and the water discharged by the second solenoid valve 74 enters the filtering structure of the water storage tank 71 through the return pipe 22 to filter out scale. This design realizes the recycling of cooling water.

[0057] The positioning ring set 83 includes a rigid ring 831 and a plastic ring 832 wrapped around the rigid ring 831 .

[0058] Based on this design, the rigid ring 831 is not easily deformed, which is convenient for improving the overall anti-deformation ability of the positioning ring group 83. The plastic ring 832 wraps the rigid ring 831 to prevent the rigid ring 831 from rusting in water.

[0059] The scraper assembly 84 includes a clamping plate 841 and a scraper blade 842 . The clamping plate 841 and the plastic ring 832 are integrally arranged, and the scraper blade 842 is fixedly arranged on the side of the clamping plate 841 .

[0060] Based on the present design, the splint 841 is also made of plastic material, and the splint 841 and the plastic ring 832 are integrally arranged. The splint 841 can bend slightly at the connection with the plastic ring 832. When the contact part between the scraper blade 842 and the inner wall of the punch assembly 5 is stuck by scale and the scraper blade 842 is suddenly significantly obstructed, the bending of the splint 841 can make it easy for the scraper blade 842 to pass through the stuck position, thereby avoiding the situation where the paddle 82, the positioning ring group 83 and the scraper strip assembly 84 are stuck by foreign objects and cannot rotate.

[0061] The side surface of the positioning shaft 81 is sleeved with an anti-slip sleeve 19 for limiting the two blades 82 .

[0062] Based on the present design, the anti-slip sleeve 19 prevents the blade 82 from being displaced in position.

[0063] Among them, two installation grooves 16 are opened inside the inner mold 3, and a vibration motor 9 is fixedly installed inside each installation groove 16. A bolt 17 is arranged inside each installation groove 16, and a sealing ring 18 is sleeved on the side of the bolt 17 to seal the notch of the installation groove 16.

[0064] Based on the present design, the structure of the bolt 17 and the sealing ring 18 is used to prevent impurities such as dust from interfering with the vibration motor 9 .

[0065] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
