Description

Technical Field

[0001] The invention relates to the technical field of thermostat shell injection molding equipment, in particular to a shell injection molding equipment for producing a cold storage refrigeration thermostat. Background Art

[0002] Thermostat refers to a series of automatic control components that produce certain special effects and conduction or disconnection actions by physically deforming the switch according to the temperature changes in the working environment. It is also called temperature control switch, temperature protector, temperature controller, or simply thermostat. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect.

[0003] In the field of thermostat housing production, especially for the manufacturing of cold storage refrigeration thermostat housings, traditional injection molding equipment has some limitations. These equipment often face challenges in continuity and stability when handling the melting and conveying of plastic particles. Specifically, traditional injection molding equipment may not be able to effectively accommodate enough plastic particles, resulting in an unstable supply of plastic melt during the injection molding process, and sometimes even a break in the flow. This unstable supply not only affects production efficiency, but may also lead to uneven quality of the final product.

[0004] In addition, traditional injection molding equipment also has limitations in plasticizing capacity. Insufficient plasticizing capacity means that plastic particles cannot be melted evenly and fully, which directly affects the uniformity and quality of the melt. Uneven melt quality may cause internal structural defects in the thermostat housing after injection molding, affecting its durability and performance. Summary of the invention

[0005] The present invention provides a shell injection molding device for producing a cold storage refrigeration temperature controller, which solves the problems mentioned in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a shell injection molding device for producing a cold storage refrigeration thermostat, comprising a workbench, a side surface of the workbench is provided with a placement groove, a storage basket is placed inside the placement groove, and further comprising:

[0007] An injection molding mechanism, the injection molding mechanism is fixedly mounted on the upper surface of the workbench, and the injection molding mechanism is used to perform injection molding on the thermostat housing;

[0008] A coordination mechanism, wherein the coordination mechanism is fixedly installed inside the injection molding mechanism and is used to assist the injection molding mechanism in working;

[0009] The injection molding mechanism includes an output seat, which is fixedly connected to the upper surface of the workbench, and a hopper is fixedly connected to the upper surface of the output seat, and a motor is fixedly connected to the side surface of the output seat, and an injection molding tube is fixedly connected to the side surface of the output seat away from the motor, and the injection molding tube is connected to a plug board at one end away from the output seat, and the lower surface of the plug board is fixedly connected to the middle upper surface of the output seat, and the plug board and the workbench are arranged perpendicular to each other, and the surface edge of the plug board close to the injection molding tube is fixedly connected to a connecting rod by bolts, and four connecting rods are provided, and the end of the connecting rod away from the plug board is fixedly connected to a mounting plate, and the mounting plate and the plug board are arranged parallel to each other.

[0010] An electric push rod is fixedly connected to the outer surface of the mounting plate away from the plug-in plate, a driving plate is slidably connected to the middle outer surface of the connecting rod, an extrusion rod is fixedly connected to the outer surface of the driving plate close to the plug-in plate, and a movable mold seat is slidably connected to the end of the extrusion rod away from the driving plate.

[0011] The surface of the movable mold seat close to the plug-in board is snap-fitted with a fixed mold seat, and the surface of the fixed mold seat away from the movable mold seat is fixedly connected to the surface of the plug-in board away from the injection tube. The interiors of the movable mold seat and the fixed mold seat are combined into a complete mold cavity, and the mold cavities of the movable mold seat and the fixed mold seat are connected to the injection tube.

[0012] A heating ring is fixedly installed on the outer surface of the injection molding tube, and four heating rings are arranged at fixed intervals on the outer surface of the injection molding tube.

[0013] Preferably, a rotating rod is provided inside the injection molding tube, and the rotating rod is rotatably connected to the output end of the motor, and a spiral plate is fixedly connected to the outer surface of the rotating rod, and the diameter of the rotating rod from the output seat side to the plug-in board side is set to gradually increase. When the shell of the thermostat needs to be injection molded, the plastic particles can be put into the hopper and the motor can be started. When the motor is started, the rotating rod in the injection molding tube will be driven to rotate. When the rotating rod rotates, the spiral plate will rotate in the injection molding tube, and then the plastic particles entering the injection molding tube will be transported to the end of the injection molding tube. At the same time, the heating ring is started to heat and melt the plastic particles in the injection molding tube. The molten plastic liquid enters the internal mold cavity of the fixed mold base through the injection tube and the plug-in board, and after cooling and finalization, the electric push rod is started. After the electric push rod is started, it will shrink, causing the movable mold base to move away from the fixed mold base. At this time, the cooled and formed thermostat housing is embedded in the movable mold base. As the electric push rod continues to shrink, the drive plate will eventually contact the mounting plate, and an extrusion force will be generated on the drive plate, thereby driving the drive plate and the movable mold base to move closer to each other, so that the extrusion rod on the drive plate squeezes the thermostat housing on the movable mold base, causing the thermostat housing to fall off the movable mold base and enter the storage basket to complete the production of the thermostat housing.

[0014] Preferably, the coordination mechanism includes a connecting tube, which is fixedly connected to the output end of the injection molding tube, a first fixed tube is arranged inside the connecting tube, the first fixed tube is fixedly connected to the outer surface of one end of the injection molding tube close to the plug-in board, the outer surface of the first fixed tube away from the injection molding tube is slidably connected to a working tube, the inner surface of the working tube away from the first fixed tube is slidably connected to a second fixed tube, the outer surface of one end of the second fixed tube away from the working tube is fixedly connected to a fixing ring, and the top of the fixing ring is fixedly connected to the inner surface of the connecting tube away from the injection molding tube.

[0015] Preferably, a connecting plate is fixedly connected to the middle inner surface of the working tube, a dredging rod is fixedly connected to the middle surface of the connecting plate close to the first fixed tube, combing holes are arranged on the outer side of the dredging rod, and six combing holes are arranged at fixed intervals around the central axis of the connecting plate.

[0016] Preferably, a pressure ring is fixedly connected to the middle outer surface of the working tube, and the surface of the pressure ring away from the working tube is slidably connected to the inner surface of the connecting tube. A guide rod is provided on the outside of the working tube, and the guide rod is fixedly connected to the surface of the injection molding tube close to the plug-in board. The guide rod passes through the pressure ring, and the pressure ring is elastically slidably connected to the guide rod through a spring.

Under the action of pressure, the unblocking rod begins to separate from the port of the injection molding tube, thereby driving the connecting plate to move toward the second fixed tube, that is, the working tube slides on the outer surfaces of the first fixed tube and the second fixed tube and moves to the side of the second fixed tube. When the unblocking rod no longer blocks the port of the injection molding tube, the working tube stops moving, that is, the plastic melt will enter the first fixed tube, and move to the side of the second fixed tube through the comb flow holes on the connecting plate on the inner surface of the working tube, and finally enter the mold cavity between the movable mold seat and the fixed mold seat.

[0018] The present invention provides a shell injection molding equipment for producing cold storage refrigeration temperature controller.

[0019] Beneficial effects:

[0020] 1. In the shell injection molding equipment produced by this cold storage refrigeration thermostat, in the process of melting and conveying plastic particles, the diameter of the rotating rod becomes larger as it approaches the plug-in board, so that more plastic particles can be accommodated at the hopper end, ensuring the continuity and stability of subsequent injection molding, avoiding the interruption of the plastic melt, and improving the plasticizing capacity. The larger rotating rod diameter helps to provide more heat and pressure, thereby melting the plastic more effectively and improving the uniformity and quality of the melt. Not only that, the rotating rod with a larger aspect ratio is also conducive to reducing pressure flow and leakage flow, and improving plasticizing capacity, which means that the flow of the melt can be controlled more accurately and material waste can be reduced.

[0021] 2. The shell injection molding equipment of the cold storage refrigeration thermostat can divert the plastic melt through the comb flow holes, which can not only speed up the flow of the plastic melt, speed up the injection molding speed, and avoid the plastic melt from being filled up in the mold cavity, but also promote the further mixing of the plastic melt and improve the overall quality of the plastic melt. When the injection molding is completed, the working tube is reset under the elastic force of the pressure ring, that is, the dredging rod is reset and the port of the injection molding tube is re-blocked, which can not only clean the port of the injection molding tube after the injection molding is completed to avoid the port of the injection molding tube from being blocked, but also avoid dust from entering the injection molding tube after the injection molding is completed to contaminate the next plastic melt, greatly improving the overall quality of the thermostat shell.

[0022] 3. In the shell injection molding equipment produced by the cold storage refrigeration thermostat, the plastic melt passes through the second fixed tube and also passes through the circular through hole composed of the expansion block, and then enters the mold cavity through the expansion block. The premise for ensuring the flow of the plastic melt is that the dredging rod does not block the port of the injection tube, that is, during injection molding, the working tube is close to the second fixed tube, thereby driving the pressure ring on its outer surface to approach the matching plate, thereby compressing the cavity between the matching plate and the pressure ring, thereby relying on air pressure to push the pressure relief box to slide outward in the installation groove, thereby driving the expansion block to slide outward in the installation groove, thereby making the circular hole composed of the expansion block The circular through hole expands, that is, when the injection pressure increases, the diameter of the circular through hole on the inner side of the expansion block becomes larger, that is, the effect of adapting to different molds is achieved, which greatly improves the applicability of the equipment. At the same time, the adaptation effect is achieved by pressurization, but the pressurization causes the circular through hole of the expansion block to expand, thereby achieving the injection pressure unchanged while adapting, avoiding the problem of injection pressure being too high or too low affecting the injection quality, and due to the existence of the limit rod, the staff can observe the size of the circular through hole according to the length of the limit rod protruding to the outside of the matching plate, and then can quickly adjust the pressure to achieve the effect of adapting the mold, making the injection pressure visualized.

DETAILED DESCRIPTION

[0032] 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.

[0033] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a shell injection molding device for producing a cold storage refrigeration thermostat, comprising a workbench 1, a placement groove 2 is opened through the side surface of the workbench 1, a storage basket 3 is placed inside the placement groove 2, and also includes:

[0034] An injection molding mechanism 4, which is fixedly mounted on the upper surface of the workbench 1 and is used to perform injection molding on the thermostat housing;

[0035] A coordination mechanism 5, which is fixedly installed inside the injection molding mechanism 4 and is used to assist the injection molding mechanism 4 in working;

[0036] The injection molding mechanism 4 includes an output seat 41, which is fixedly connected to the upper surface of the workbench 1, and a hopper 42 is fixedly connected to the upper surface of the output seat 41, and a motor 43 is fixedly connected to the side surface of the output seat 41, and an injection molding tube 44 is fixedly connected to the side surface of the output seat 41 away from the motor 43, and the injection molding tube 44 is connected to the end away from the output seat 41. The plug-in board 45 is connected to the middle upper surface of the output seat 41, and the plug-in board 45 and the workbench 1 are arranged perpendicular to each other, and the surface edge of the plug-in board 45 close to the injection molding tube 44 is fixedly connected to a connecting rod 46 by bolts, and four connecting rods 46 are provided, and the end of the connecting rod 46 away from the plug-in board 45 is fixedly connected to a mounting plate 47, and the mounting plate 47 and the plug-in board 45 are arranged parallel to each other.

[0037] An electric push rod 48 is fixedly connected to the outer surface of the mounting plate 47 away from the plug-in plate 45, a driving plate 49 is slidably connected to the middle outer surface of the connecting rod 46, an extrusion rod 410 is fixedly connected to the outer surface of the driving plate 49 close to the plug-in plate 45, and a movable mold base 411 is slidably connected to the end of the extrusion rod 410 away from the driving plate 49.

[0038] The surface of the movable mold seat 411 close to the plug-in board 45 is snap-fitted with a fixed mold seat 412, and the surface of the fixed mold seat 412 away from the movable mold seat 411 is fixedly connected to the surface of the plug-in board 45 away from the injection tube 44. The interiors of the movable mold seat 411 and the fixed mold seat 412 are combined into a complete mold cavity, and the mold cavities of the movable mold seat 411 and the fixed mold seat 412 are connected to the injection tube 44.

[0039] A heating ring 413 is fixedly installed on the outer surface of the injection tube 44. Four heating rings 413 are arranged at fixed intervals around the outer surface of the injection tube 44. A feed port 414 is penetrated through the outer surface of the injection tube 44 away from the plug-in board 45. The feed port 414 is arranged inside the output seat 41, and the feed port 414 is connected to the bottom of the hopper 42.

[0040] A rotating rod 415 is arranged inside the injection tube 44, and the rotating rod 415 is rotatably connected to the output end of the motor 43. A spiral plate 416 is fixedly connected to the outer surface of the rotating rod 415, and the diameter of the rotating rod 415 is set to gradually increase from the output seat 41 side to the plug-in plate 45 side.

[0041] During operation, when it is necessary to perform injection molding on the shell of the temperature controller, plastic particles can be put into the hopper 42 and the motor 43 is started. When the motor 43 is started, the rotating rod 415 in the injection molding tube 44 will be driven to rotate. When the rotating rod 415 rotates, the spiral plate 416 will rotate in the injection molding tube 44, and then the plastic particles entering the injection molding tube 44 will be transported to the end of the injection molding tube 44. At the same time, the heating ring 413 is started to heat and melt the plastic particles in the injection molding tube 44. The heated and melted plastic liquid passes through the injection molding tube 44 and the plug-in board 45 into the internal mold cavity of the fixed mold seat 412, and after cooling and finalizing, the electric push rod 48 is started. After the electric push rod 48 is started, it will shrink, thereby causing the movable mold seat 411 to move away from the fixed mold seat 412. At this time, the cooled and formed temperature controller shell is embedded in the movable mold seat 411. As the electric push rod 48 continues to shrink, the drive plate 49 will eventually contact the mounting plate 47, and a squeeze force will be generated on the drive plate 49. The pressure drives the driving plate 49 and the movable mold base 411 to move toward each other, so that the temperature controller shell on the movable mold base 411 is squeezed by the extrusion rod 410 on the driving plate 49, causing the temperature controller shell to fall off the movable mold base 411 and enter the storage basket 3 to complete the production of the temperature controller shell. In the process of melting and conveying the plastic particles, since the diameter of the rotating rod 415 becomes larger as it approaches the plug-in plate 45, more plastic particles can be accommodated at the hopper 42 end, ensuring the continuity and stability of subsequent injection molding, avoiding the interruption of the plastic melt, and improving the plasticizing capacity. The larger diameter of the rotating rod 415 helps to provide more heat and pressure, thereby more effectively melting the plastic and improving the uniformity and quality of the melt. Not only that, the rotating rod 415 with a larger aspect ratio is also conducive to reducing pressure flow and leakage flow, and improving plasticizing capacity, which means that the flow of the melt can be controlled more accurately and material waste can be reduced.

[0042] Second embodiment: Figures 1 to 8 As shown, the coordination mechanism 5 includes a connecting tube 51, which is fixedly connected to the output end of the injection molding tube 44. A first fixed tube 52 is arranged inside the connecting tube 51, and the first fixed tube 52 is fixedly connected to the outer surface of one end of the injection molding tube 44 close to the plug-in board 45. A working tube 53 is slidably connected to the outer surface of one end of the first fixed tube 52 away from the injection molding tube 44, and a second fixed tube 54 is slidably connected to the inner surface of one end of the working tube 53 away from the first fixed tube 52. A fixing ring 55 is fixedly connected to the outer surface of one end of the second fixed tube 54 away from the working tube 53, and the top of the fixing ring 55 is fixedly connected to the inner surface of the connecting tube 51 away from the injection molding tube 44.

[0043] A connecting plate 56 is fixedly connected to the middle inner surface of the working tube 53, a dredging rod 57 is fixedly connected to the middle surface of the connecting plate 56 close to the first fixed tube 52, combing holes 58 are arranged on the outer side of the dredging rod 57, and six combing holes 58 are arranged at fixed intervals around the central axis of the connecting plate 56.

[0044] A pressure ring 59 is fixedly connected to the middle outer surface of the working tube 53, and the surface of the pressure ring 59 away from the working tube 53 is slidably connected to the inner surface of the connecting tube 51. A guide rod 510 is arranged on the outer side of the working tube 53, and the guide rod 510 is fixedly connected to the surface of the injection tube 44 on the side close to the plug-in board 45. The guide rod 510 passes through the pressure ring 59, and the pressure ring 59 is elastically slidably connected to the guide rod 510 through a spring.

[0045] A matching plate 511 is fixedly connected to the surface of one end of the connecting tube 51 away from the injection tube 44. A mounting groove 512 is provided through the middle of the matching plate 511. The mounting groove 512 is arranged in a cross shape. A flow expansion block 513 is slidably connected inside the mounting groove 512. Four flow expansion blocks 513 are arranged in contact with each other around the central axis of the matching plate 511. The four flow expansion blocks 513 are combined to form a circular through hole. A pressure relief box 514 is fixedly connected to the outer surface of the pressure relief box 514. The pressure relief box 514 is slidably connected to the outer inner surface of the mounting groove 512. A limiting rod 515 is fixedly connected to the outer surface of the pressure relief box 514. The end of the limiting rod 515 away from the pressure relief box 514 passes through the matching plate 511.

[0046] During operation, when the plastic melt passes through the injection tube 44, it will squeeze the dredging rod 57. Under the action of pressure, the dredging rod 57 begins to separate from the port of the injection tube 44, thereby driving the connecting plate 56 to move toward the second fixed tube 54, that is, the working tube 53 slides on the outer surfaces of the first fixed tube 52 and the second fixed tube 54 and moves to the side of the second fixed tube 54. When the dredging rod 57 no longer blocks the port of the injection tube 44, the working tube 53 stops moving, that is, the plastic melt enters the first fixed tube 52, and moves to the side of the second fixed tube 54 through the combing holes 58 on the connecting plate 56 on the inner surface of the working tube 53, and finally enters the movable mold seat 411 and the fixed mold seat 412. In the mold cavity between the two, the plastic melt is diverted by the comb flow hole 58, which can not only speed up the flow of the plastic melt and the injection speed, and avoid the plastic melt being filled up in the mold cavity, but also promote the further mixing of the plastic melt and improve the overall quality of the plastic melt. When the injection molding is completed, the working tube 53 is reset under the elastic force of the pressure ring 59, that is, the dredging rod 57 is driven to reset and the port of the injection molding tube 44 is re-blocked, which can not only realize the cleaning of the port of the injection molding tube 44 after the injection molding is completed to avoid the port of the injection molding tube 44 being blocked, but also prevent dust from entering the injection molding tube 44 after the injection molding is completed to contaminate the next plastic melt, which greatly improves The overall quality of the temperature controller shell, and the plastic melt will pass through the circular through hole composed of the expansion block 513 after passing through the second fixed tube 54, and enter the mold cavity after passing through the expansion block 513. The premise for ensuring the circulation of the plastic melt is that the dredging rod 57 does not block the port of the injection tube 44, that is, during injection molding, the working tube 53 is close to the side of the second fixed tube 54, thereby driving the pressure ring 59 on its outer surface to approach the matching plate 511, thereby compressing the cavity between the matching plate 511 and the pressure ring 59, thereby relying on air pressure to push the pressure relief box 514 to slide outward in the installation groove 512, thereby driving the expansion block 513 to slide outward in the installation groove 512, thereby making the expansion block 513 The circular through hole formed by the expansion block 513 is enlarged, that is, when the injection pressure increases, the diameter of the circular through hole on the inner side of the expansion block 513 becomes larger, that is, the effect of adapting to different molds is achieved, which greatly improves the applicability of the equipment. At the same time, the adaptation effect is achieved by pressurization, but the pressurization causes the circular through hole of the expansion block 513 to expand, thereby achieving the goal of keeping the injection pressure unchanged while adapting, avoiding the problem of too high or too low injection pressure affecting the injection quality, and due to the existence of the limit rod 515, the staff can observe the size of the circular through hole according to the length of the limit rod 515 protruding to the outside of the matching plate 511, and then can quickly adjust the pressure to achieve the effect of adapting the mold, so that the injection pressure can be visualized.
