Abstract
Description
Technical Field
[0001] This utility model relates to the field of cylindrical grinding machine technology, and in particular to a cylindrical grinding machine for mold processing. Background Technology
[0002] An external cylindrical grinding machine is a precision machining tool used for grinding cylindrical or conical outer surfaces. It mainly consists of a bed, worktable, grinding wheel head, headstock, and tailstock. The bed is the basic component of the machine tool, used to support and mount other components. The worktable reciprocates longitudinally along the bed guideways, driving the workpiece in the grinding process. The grinding wheel head is mounted on the bed and can move laterally to adjust the position between the grinding wheel and the workpiece. The headstock is used to mount the workpiece and rotate it. The tailstock works in conjunction with the headstock to support the workpiece. External cylindrical grinding machines achieve precision grinding of the workpiece's outer cylindrical surface through the high-speed rotation of the grinding wheel and the low-speed rotation and axial movement of the workpiece. They can achieve very high dimensional accuracy and surface finish, and are widely used in machinery manufacturing, automotive, aerospace, and other fields, making them indispensable equipment for machining high-precision shaft parts.
[0003] A search revealed that the Chinese patent announcement number is CN215616897U. This utility model relates to the field of mold processing technology, and in particular to an external cylindrical grinding machine for mold processing. It includes an external cylindrical grinding machine body. Several slide rails are fixedly arranged on the upper inner side of the external cylindrical grinding machine body. Several first sliders are slidably arranged on the surface of the slide rails. A first drive motor is fixedly arranged on the upper end of each first slider. A first hydraulic cylinder is fixedly arranged at one end of the first drive motor, and a three-grip chuck is driven at the other end of the first drive motor. A second drive motor drives a lead screw to rotate, thereby driving a lifting mounting plate to raise and lower the height of the grinding machine. A third hydraulic cylinder drives the grinding machine to slide inside the slide groove via the second slider, adjusting the lateral distance. During processing, the second hydraulic cylinder drives the sliding door to slide and close. Debris and fumes pass through the partition mesh plate, and the exhaust pump draws them into the waste bin through a funnel, where they are filtered by a filter screen before being discharged, thus purifying the working environment.
[0004] Although the aforementioned patent mentions in its beneficial effects that "smaller workpieces can be directly clamped by a three-grip chuck, while larger workpieces can be clamped by another rotating top plate using a three-grip chuck. The first hydraulic cylinder drives the first drive motor to slide on the slide rail surface via the first slider, thereby clamping the workpieces through the rotating top plates at both ends, which can fix workpieces of different sizes," it cannot effectively clamp the mold while cleaning up the grinding debris. Consequently, the debris affects the stability of the clamping. Therefore, an external cylindrical grinding machine for mold processing is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an external cylindrical grinding machine for mold processing, aiming to improve the problem that some existing external cylindrical grinding machines cannot effectively clamp the mold and clean up the debris.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an external cylindrical grinding machine for mold processing, comprising a support plate, a housing fixedly connected to the top of the support plate, a control mechanism provided at the bottom of the support plate, a clamping mechanism provided inside the support plate, a circulation mechanism provided outside the support plate, two movable doors provided on the front side of the housing, and grinding modules installed on both the left and right sides inside the housing.
[0007] The clamping mechanism includes a drive assembly, which is externally mounted on the inside right side of the housing. The drive assembly is externally threaded with two threaded sleeves. A fan ring is fixedly connected to the inside rear side of the housing. Clamping plates are fixedly connected to the outside of both threaded sleeves. Sliding grooves are formed inside both clamping plates. Sliding sleeves are fixedly connected to the inside front side of both clamping plates. A guide rod is fixedly connected to the inside of the housing. A placement plate is fixedly connected to the inside of the housing.
[0008] Through the above technical solution: When the drive component is activated, it operates on the right side inside the housing. Because it is threadedly connected to the threaded sleeve, the drive component's operation causes the threaded sleeve to move along a specific trajectory. The threaded sleeve drives the clamping plate fixed to it to move synchronously. The two clamping plates move towards or away from each other, realizing the clamping and releasing action of the mold to be processed. During this process, the sliding groove inside the clamping plate slides in cooperation with the fan ring fixed on the rear side inside the housing, ensuring the accurate movement direction of the clamping plate and providing a guiding effect to prevent deviation from the predetermined path. The sliding sleeve on the front side inside the clamping plate slides on the guide rod fixed inside the housing, greatly improving the stability of the clamping plate during movement and avoiding shaking or twisting. This ensures the clamping accuracy of the mold to be processed, providing a stable mold fixing foundation for subsequent grinding processes. The placement plate supports the clamping plate, ensuring a smooth clamping process.
[0009] As a further description of the above technical solution:
[0010] The drive assembly includes a motor, which is externally mounted on the inside right side of the housing. A rotating rod is fixedly connected to the output end of the motor, and the rotating rod has an external thread.
[0011] Through the above technical solution: when the motor starts running, it drives the rotating rod to rotate synchronously. Since the rotating rod has an external thread, this structural design allows the threaded sleeve connected to it to be displaced along the axial direction of the rotating rod when the rotating rod rotates, based on the principle of thread transmission. This provides the power transmission and motion basis for the subsequent clamping action of the clamping plate to achieve the mold clamping action.
[0012] As a further description of the above technical solution:
[0013] The circulation mechanism includes a return pipe, the front side of which is fixedly connected to the rear side of the inner side of the housing. A suction pump is installed on the outside of the return pipe. A water tank is installed on the top of the housing. A water inlet pipe is fixedly connected to the top left side of the water tank. A water pump is installed on the front side of the top of the housing. A flow pipe is fixedly connected to the output end of the water pump. Multiple nozzles are installed at the bottom of the flow pipe.
[0014] Through the above technical solution: During operation, the suction pump starts, drawing the used water from the bottom of the housing back to the water tank installed on the top of the housing through the return pipe, thus realizing water recycling. The water inlet pipe on the left side of the top of the water tank can be used to replenish new water. When the mold needs to be cooled and rinsed, the water pump installed on the front of the top of the housing is turned on. The water pump draws water from the water tank from the input end and delivers it to the flow pipe fixedly connected to it through the output end. Multiple nozzles installed at the bottom of the flow pipe spray water evenly onto the mold to be processed, achieving the effect of cooling and rinsing the mold. The entire circulation mechanism realizes the recycling of water, ensuring the cooling and rinsing needs during the mold processing.
[0015] As a further description of the above technical solution:
[0016] The control mechanism includes a control box, the top of which is fixedly connected to the bottom of the support plate, and a control panel is fixedly connected to the front of the control box.
[0017] Through the above technical solution: during operation, the operator inputs commands through control buttons, knobs and other components on the control panel. The command signals are transmitted to the control circuit in the control box, which then issues start or stop commands to the grinding machine's motor, suction pump, water pump and other equipment, thereby regulating the working status of each component of the grinding machine, completing various operations of mold processing, ensuring that the entire grinding machine operates stably and accurately, and meeting the mold processing requirements.
[0018] As a further description of the above technical solution:
[0019] The placement plate has multiple holes inside and a drop groove inside. A collection frame is detachably connected to the bottom of the placement plate.
[0020] Through the above technical solution: when the mold is cooled and rinsed, water flows through these holes and flows from the surface of the placement plate into the bottom of the housing, realizing the recycling of cooling water and ensuring the effective use of water resources. At the same time, the placement plate is also equipped with a drop groove. During the mold grinding process, the debris generated falls down through the drop groove. The collection frame that can be detachably connected to the bottom of the placement plate can catch the debris falling from the drop groove, which is convenient for centralized collection and cleaning, keeping the working environment inside the grinding machine clean. The detachable connection method also makes it convenient for operators to clean the collection frame regularly, maintaining the continuous and efficient operation of the grinding machine.
[0021] As a further description of the above technical solution:
[0022] The external thread of the threaded sleeve is connected to the outside of the rotating rod, and the external slidable connection of the fan ring is connected to the inside of the groove.
[0023] Through the above technical solution: when the rotating rod rotates under the drive of the motor, the threaded sleeve will move linearly along the axial direction of the rotating rod due to the transmission action of the thread. At the same time, the fan ring is slidably connected to the groove opened inside the clamping plate. During the process of the threaded sleeve driving the clamping plate to move, the fan ring slides in the groove.
[0024] As a further description of the above technical solution:
[0025] The inner part of the sliding sleeve is slidably connected to the outside of the guide rod, and the bottom of the clamping plate is slidably connected to the top of the placement plate.
[0026] Through the above technical solution: when the threaded sleeve drives the clamping plate to move, the sliding sleeve slides along the outside of the guide rod, which further enhances the stability of the clamping plate when it moves, effectively prevents it from twisting or shaking during movement, and greatly improves the clamping accuracy of the mold.
[0027] As a further description of the above technical solution:
[0028] One end of the return pipe is fixedly connected to the rear side of the interior of the shell, and the other end of the return pipe is fixedly connected to the interior of the water tank.
[0029] Through the above technical solution: when the suction pump starts to operate, water is drawn into the return pipe from the bottom inside the shell. Under the suction of the suction pump, the water flows along the return pipe and is finally transported from the rear inside the shell to the inside of the water tank. This realizes the return process of water from the shell to the water tank and achieves the recycling and reuse of water resources.
[0030] As a further description of the above technical solution: the input end of the water pump is fixedly connected to the inside of the water tank, and the outside of the collection frame is slidably connected to the inside of the housing.
[0031] The above technical solution works as follows: when the water pump starts, water in the tank is drawn into the pump input end by its power, and then transported to the flow pipe through the pump output end. The water is then sprayed onto the mold to be processed through the nozzle, thereby cooling and rinsing the mold and meeting the cooling and cleaning requirements during mold processing.
[0032] This utility model has the following beneficial effects:
[0033] 1. In this utility model, a motor drives a rotating rod to rotate, which, through its threaded connection with a threaded sleeve, causes the threaded sleeve to move axially, thereby displacing the clamping plate connected to it. During this process, the sliding groove inside the clamping plate, the fan ring on the rear side of the housing, the sliding sleeve on the front side of the clamping plate, and the guide rod work together to ensure stable movement of the clamping plate, adapting to the clamping requirements of various molds and ensuring grinding accuracy. Simultaneously, the detachable collection frame connected to the bottom of the placement plate cooperates with the drop trough. After grinding, the motor drives the clamping plate to push the debris into the drop trough, where it falls into the collection frame, achieving efficient cleaning, maintaining equipment cleanliness, and reducing debris interference with processing.
[0034] 2. In this invention, a water pump draws water from the water tank and sprays it onto the mold surface through multiple nozzles via a flow pipe. This effectively removes grinding heat, lowers the mold temperature, and improves processing quality. The cooled water and debris fall onto the placement plate, and the water flows through holes into the bottom of the housing. It is then pumped back to the water tank by a suction pump outside the return pipe, achieving recycling. This saves water resources, reduces costs, minimizes wastewater discharge, and ensures a continuous supply of cooling water for the grinding machine during operation. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0043] Reference Figures 1 to 3 This utility model provides an embodiment of an external cylindrical grinding machine for mold processing, including a support plate 1. The support plate 1 serves as the basic support structure for the entire external cylindrical grinding machine, stabilizing the equipment. A housing 2 is fixedly connected to the top of the support plate 1, which encapsulates and protects the internal structure of the grinding machine. A control mechanism 3 is provided at the bottom of the support plate 1. The control mechanism 3 includes a control box 31, the top of which is fixedly connected to the bottom of the support plate 1. The control box 31 is the core part of the control mechanism 3, integrating various control circuits and electronic components. A control panel 32 is fixedly connected to the front of the control box 31. The control panel 32 is installed on the front of the control box 31 and serves as the interface for the operator to interact with the grinding machine. The control panel 32 is equipped with various control buttons, knobs, indicator lights, and a display screen. The operator can start or stop various parts of the grinding machine through the control buttons.
[0044] Specifically, the support plate 1 serves to stabilize the equipment, the control box 31 is the core of the control mechanism 3, and integrates various control circuits and electronic components. The control panel 32, which is fixedly connected to the front of the control box, serves as the interface between the operator and the grinding machine. It is equipped with control buttons, knobs, indicator lights and display screens. The operator can start or stop the various parts of the grinding machine through the control buttons to realize the operation and control of the grinding machine.
[0045] Reference Figures 2 to 4The support plate 1 has a clamping mechanism 4 inside and a circulation mechanism 5 outside. The front of the housing 2 has two movable doors 6. Grinding modules 7 are installed on both the left and right sides inside the housing 2. The clamping mechanism 4 includes a drive assembly 41, which includes a motor 4101. The motor 4101 is externally mounted on the right side inside the housing 2 and is the power source for the drive assembly 41. A rotating rod 4102 is fixedly connected to the output end of the motor 4101. The rotating rod 4102 has an external thread 4103. The drive assembly 41 is externally mounted on the right side inside the housing 2, and two threaded sleeves 42 are threadedly connected to its external threads. The external thread of the threaded sleeve 42 is connected to the outside of the rotating rod 4102. When the motor 4101 drives the rotating rod 4102 to rotate, the threaded sleeve 42 will be displaced along the axial direction of the rotating rod 4102 due to the threaded connection with the rotating rod 4102. The inner rear side of the housing 2 is fixedly connected to the fan ring 43. When the clamping plate 44 moves with the threaded sleeve 42, the fan ring 43 slides in the slide groove 45, which plays a guiding and limiting role, and at the same time can prevent water and debris from falling to the outside of the rotating rod 4102. The outside of both threaded sleeves 42 is fixedly connected to the clamping plate 44. When the clamping plate 44 moves, the bottom slides on the top of the placement plate 48. The placement plate 48 can support the clamping plate 44.
[0046] The inner surface of the clamping plate 44 is usually fitted with rubber pads or other soft materials to increase friction with the mold and prevent damage to the mold surface during clamping. Both clamping plates 44 have internal grooves 45, and the outer surface of the fan ring 43 is slidably connected to the inside of the grooves 45. The grooves 45 and the fan ring 43 cooperate to provide guidance and limiting functions. Sleeves 46 are fixedly connected to the front inner surface of both clamping plates 44, and guide rods 47 are fixedly connected to the inside of the housing 2. When the clamping plate 44 moves with the threaded sleeve 42, the sleeves 46 slide outside the guide rods 47, further improving the stability of the clamping plate 44's movement and preventing twisting or shaking during movement, thereby ensuring precise clamping of the mold to be processed. The sliding sleeve 46 is slidably connected to the outside of the guide rod 47. The housing 2 is fixedly connected to the inside of the placement plate 48. The bottom of the clamping plate 44 is slidably connected to the top of the placement plate 48. The placement plate 48 has multiple holes 49 inside. The function of the holes 49 is to allow water to flow into the bottom of the housing 2 during cooling and rinsing of the mold, so as to realize water recycling. The placement plate 48 has a drop groove 410 inside. The drop groove 410 is for convenient collection of debris pushed by the clamping plate 44. The bottom of the placement plate 48 is detachably connected to a collection frame 411. The outside of the collection frame 411 is slidably connected to the inside of the housing 2. The collection frame 411 is used to collect debris generated during the grinding process.
[0047] Specifically, when the motor 4101 drives the rotating rod 4102 to rotate, the threaded sleeve 42 moves axially along the rotating rod 4102, thereby moving the clamping plate 44 fixedly connected to it. A soft material is installed on the inner side of the clamping plate 44 to prevent damage to the mold. Its internal sliding groove 45 slides in conjunction with the fan ring 43 fixed to the rear side of the housing 2, achieving guidance and limiting, while preventing water and debris from falling onto the rotating rod 4102. The sliding sleeve 46 on the front side of the clamping plate 44 slides on the guide rod 47 fixed inside the housing 2, improving the stability of the clamping plate 44's movement and ensuring clamping accuracy. The clamping plate 44 slides on top of the placement plate 48. The placement plate 48 has multiple holes 49 for cooling and rinsing water flow recovery, and also has a drop groove 410 and a detachably connected collection frame 411 for collecting debris generated during grinding.
[0048] Reference Figure 2 , Figure 3 and Figure 5 The circulation mechanism 5 includes a return pipe 51. The front side of the return pipe 51 is fixedly connected to the rear side of the interior of the housing 2. One end of the return pipe 51 is fixedly connected to the rear side of the interior of the housing 2, and the other end is fixedly connected to the interior of the water tank 53. The return pipe 51 is used to return water from the bottom side of the interior of the housing 2 to the water tank 53. A suction pump 52 is installed outside the return pipe 51. The suction pump 52 can effectively draw water from the bottom side of the interior of the housing 2 into the water tank 53. The water tank 53 is installed on the top of the housing 2. 53 is used to store water required for cooling and rinsing the mold. A water inlet pipe 54 is fixedly connected to the top left side of the water tank 53. A water pump 55 is installed on the top front side of the housing 2. The water pump 55 is a power device that delivers water from the water tank 53 to the nozzle 57. The input end of the water pump 55 is fixedly connected to the inside of the water tank 53. The output end of the water pump 55 is fixedly connected to a flow pipe 56. Multiple nozzles 57 are installed at the bottom of the flow pipe 56. The nozzles 57 are used to spray water onto the mold to be processed to achieve cooling and rinsing of the mold.
[0049] Specifically, one end of the return pipe 51 is connected to the rear interior of the housing 2, and the other end is connected to the interior of the water tank 53. An externally installed suction pump 52 can effectively draw water from the bottom of the housing 2 back into the water tank 53, achieving water recycling. The water tank 53 is installed on the top of the housing 2 for water storage, and its top left-side inlet pipe 54 can replenish water. The input end of the water pump 55 on the front top of the housing 2 is connected to the interior of the water tank 53, and its output end is connected to the flow pipe 56. The water pump 55, acting as a power device, transports water from the water tank 53 to multiple nozzles 57 installed at the bottom of the flow pipe 56. The nozzles 57 spray water onto the mold to be processed, cooling and rinsing the mold.
[0050] Working Principle: When using this cylindrical grinding machine for mold processing, first open the movable door 6, then place the mold to be processed on top of the placement plate 48. Then, start the drive assembly 41 to rotate the rotating rod 4102. The threaded connection between the rotating rod 4102 and the threaded sleeve 42 causes the threaded sleeve 42 to shift with the rotation of the rotating rod 4102, which in turn causes the clamping plate 44 to shift. This causes the sliding sleeve 46 to slide outside the guide rod 47, ensuring the stability of the clamping plate 44's movement. The displacement of the clamping plate 44 allows for the clamping and fixing of molds of different sizes. Then, the control mechanism 3 controls the grinding module 7 to start working, thereby achieving the grinding of the mold. During the process, the water pump 55 can be activated to draw water from the inside of the water tank 53 and spray it out through the flow pipe 56 and the nozzle 57, thereby cooling and rinsing the mold. The waste and water will fall to the top of the placement plate 48. The waste will remain on the top of the placement plate 48, and the water will enter the bottom of the inside of the shell 2 through the hole 49. Then, the suction pump 52 can be used to draw the water into the inside of the water tank 53 through the return pipe 51 for recycling. Then, the processing mold can be taken out, and then the motor 4101 can be activated again to drive the clamping plate 44 to move, so that the waste on the top of the placement plate 48 can be pushed into the inside of the drop groove 410 and finally collected by the collection frame 411. Thus, the waste can be cleaned and collected by disassembling the collection frame 411.
[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
