Description

Technical Field

[0001] This utility model relates to the field of surface grinding of mold parts, and in particular to a surface grinding device for mold parts. Background Technology

[0002] Surface grinding of mold parts is a common machining process, mainly used to improve the surface accuracy and smoothness of mold parts. Surface grinding removes irregularities from the surface of mold parts, ensuring dimensional accuracy, flatness, and surface quality.

[0003] Existing technologies, such as the utility model patent with publication number CN222386630U, disclose a grinding device for processing mold parts. This device includes a bottom support plate, on which a clamping assembly and a bracket are mounted. A grinding mechanism is mounted on the bracket, and a dust collection mechanism is mounted on the grinding mechanism. When the grinding mechanism grinds the workpiece, the dust collection mechanism sucks away and collects the grinding debris. The clamping assembly includes a fixing plate welded to the bottom support plate, with a fastening pin threaded onto the fixing plate. The end of the fastening pin is fixedly connected to the clamping plate. This relates to the field of mold part grinding technology. By setting up a dust collection mechanism, when grinding the workpiece, a protective cover encloses the grinding area of ​​the workpiece, effectively sucking away debris and preventing debris from splashing. This facilitates debris collection and helps maintain the cleanliness of the processing area.

[0004] When grinding the flat surface of mold parts, usually only a single flat surface of the part can be ground. However, many parts need to be ground on both sides. After one side of the part is ground, the workpiece needs to be re-clamped to grind the other side, which increases the time cost of operation and reduces the processing efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when grinding the plane of a mold part, only a single plane of the part can usually be ground, while the part needs to be ground on both sides. After one side of the part is ground, the workpiece needs to be re-clamped to grind the other side, which increases the time cost of operation and reduces the processing efficiency.

[0006] To solve the above technical problems, this utility model provides a surface grinding device for mold parts, comprising: two bases, a mold part body, and two fixing devices. A support frame is fixedly connected to the upper surface of each of the two bases. The support frame has an "L"-shaped cross-section. A round rod is rotatably connected to the inner wall of the support frame. The ends of the two round rods, close to each other, are fixedly connected to the same carrying frame. The mold part body is located on the inner wall of the carrying frame. One end of one of the round rods is provided with a flipping device. The flipping device includes a fixing block. The lower surface of the fixing block is fixedly connected to the base. An adjusting rod is threaded through the inner wall of the fixing block. A push block is rotatably connected to one end of the adjusting rod. The lower surface of the push block is slidably connected to the surface of the base. An adjusting block is fixedly connected to the upper surface of the push block. The adjusting block has a wedge-shaped cross-section. One of the support frames is fixedly connected to a slide rail on one side. A guide block is slidably connected to the surface of the slide rail. A toothed block is fixedly connected to one side of the guide block. A moving block is fixedly connected to the lower surface of the toothed block. The moving block has a wedge-shaped cross-section and one side of the moving block abuts against an adjusting block. A limit block is fixedly connected to one side of the support frame. The limit block has an "L"-shaped cross-section. A rod slides through the inner wall of one end of the limit block. A connecting block is fixedly connected to one end of the rod. A spring is fitted on the arc surface of the rod. The two ends of the spring are fixedly connected to the limit block and the connecting block, respectively. A gear is fixedly connected to one end of one of the round rods. The tooth surface of the gear meshes with the toothed block. The inner wall of the gear is inserted into the rod. An insertion hole is opened on one side surface of the gear. The cross-sectional dimensions of the insertion hole are adapted to the insertion rod.

[0007] The effect achieved by the above components is as follows: when one side of the mold part body is ground and the other side needs to be ground, first pull the connecting block so that the connecting block carries the insert rod away from the gear. Then rotate the adjusting rod so that the adjusting rod pushes the push block to move. In this way, the adjusting block moves with it, and the moving block is pushed upward so that the toothed block carries the guide block upward along the slide rail. The gear is rotated, and the round rod also rotates. The carrying frame rotates until the carrying frame is rotated 180°. At this time, the insert rod is exactly aligned with the insertion hole. Release the connecting block, and the insert rod is carried into the insertion hole under the action of the spring. In this way, the carrying frame is fixed, and then the grinding can continue.

[0008] Preferably, a plurality of friction grooves are formed on the arc surface of one end of the adjusting rod, and the plurality of friction grooves are evenly distributed on the arc surface of one end of the adjusting rod.

[0009] The effect achieved by the above components is that the friction groove increases the friction force, making it easier for the operator to rotate the adjusting rod.

[0010] Preferably, a slider is fixedly connected to the lower surface of the push block, and a groove is provided on the base corresponding to the position of the slider, with the inner wall of the groove slidably connected to the slider.

[0011] The effect achieved by the above components is that when the adjusting rod is rotated to move the push block, the push block moves along the direction of the slide groove with the slider, which plays a guiding role.

[0012] Preferably, a pull ring is fixedly connected to the arc surface of the connecting block, and the pull ring has a circular cross-section.

[0013] The effect achieved by the above components is that the connecting block can be pulled with the help of the pull ring, making it more convenient and faster.

[0014] Preferably, the fixing device is disposed on both sides of the loading frame. The fixing device includes a fixing base, the lower surface of which is fixedly connected to the loading frame. A rotating rod is threadedly connected to the inner wall of the fixing base. A connecting frame is fixedly connected to the upper surface of the rotating rod. A pressing rod is threaded through the inner wall of one end of the connecting frame. An auxiliary pad is fixedly connected to the lower surface of the pressing rod. The lower surface of the auxiliary pad abuts against the surface of the mold part body. The auxiliary pad is a rubber pad.

[0015] The aforementioned components achieve the following effect: When it is necessary to fix the mold part body, first place the mold part body into the inner wall of the carrying frame, then rotate the connecting frame, causing the connecting frame to rotate with the rotating rod, while simultaneously moving the connecting frame downwards until the extrusion rod on the connecting frame can extrude the mold part body. Then rotate the extrusion rod, causing the extrusion rod to move downwards with the auxiliary pad until the auxiliary pad abuts against the mold part body, thus fixing the mold part body. When the mold part body is finished grinding and needs to be removed, rotate the extrusion rod in the opposite direction, causing the extrusion rod to move upwards with the auxiliary pad to a certain position. Then rotate the connecting frame, causing the connecting frame to rotate with the rotating rod, while simultaneously moving upwards until it reaches a certain position, making it easier to remove the mold part body.

[0016] Preferably, one end of the extrusion rod is fixedly connected to a handle, and the handle has a circular cross-section.

[0017] The effect achieved by the above-mentioned components is that the extrusion rod can be rotated with the help of the handle, which makes the operation more convenient.

[0018] Preferably, the arc surface of the handle is provided with a plurality of anti-slip textures, and the plurality of anti-slip textures are evenly distributed on the arc surface of the handle.

[0019] The effect achieved by the above components is that the anti-slip texture increases friction, making it easier for the operator to turn the extrusion rod with the help of the handle.

[0020] Compared with related technologies, the mold part surface grinding device provided by this utility model has the following beneficial effects:

[0021] This invention provides a surface grinding device for mold parts. When grinding the mold part body, the mold part body needs to be positioned first, and then one side of the mold part body is ground. After grinding, the mold part body needs to be flipped to grind the other side. First, the connecting block is pulled by a pull ring, causing the connecting block to move the insert rod away from the gear. Then, the adjusting rod is rotated, causing the adjusting rod to push the push block to move. The push block moves the slider along the direction of the slide groove, and the adjusting block moves with the push block. The moving block is pushed upward by the adjusting block, causing the toothed block to move upward along the slide rail with the guide block. The gear is rotated by the toothed block, and the round rod also rotates, causing the carrying frame to rotate until the carrying frame is flipped 180 degrees. At this point, the insert rod is aligned with the insertion hole. The connecting block is released, and the insert rod is inserted into the insertion hole under the action of the spring, thus fixing the carrying frame. Then, the other side of the mold part body can be ground. By operating the flipping device, the function of flipping the mold part body is achieved.

[0022] Before grinding the mold part body, it needs to be positioned. First, place the mold part body into the inner wall of the carrying frame. Then, rotate the connecting frame, causing it to rotate along with the rotating rod. Simultaneously, the connecting frame moves downward until the pressing rod on the connecting frame can press the mold part body. Then, using the handle, rotate the pressing rod, causing it to move downward along with the auxiliary pad until the auxiliary pad abuts against the mold part body. This fixes the mold part body in place. When the mold part body needs to be removed after grinding, use the handle to rotate the pressing rod in the opposite direction, causing it to move upward along with the auxiliary pad to a certain position. Then, rotate the connecting frame, causing it to rotate along with the rotating rod, moving upward simultaneously until it reaches a certain position, facilitating the removal of the mold part body. Finally, remove the mold part body. By operating the fixing device, the mold part body is fixed and positioned. Attached Figure Description

[0031] In the embodiments of this utility model, please refer to Figure 1 and Figure 3The flipping device 6 includes a fixed block 601, the lower surface of which is fixedly connected to the base 1. An adjusting rod 602 is threaded through the inner wall of the fixed block 601. A push block 604 is rotatably connected to one end of the adjusting rod 602. The lower surface of the push block 604 is slidably connected to the surface of the base 1. An adjusting block 607 is fixedly connected to the upper surface of the push block 604.

A connecting block 614 is fixedly connected to one end of the rod 613. A spring 616 is sleeved on the arc surface of the rod 613. The two ends of the spring 616 are fixedly connected to the limiting block 612 and the connecting block 614, respectively. A gear 617 is fixedly connected to one end of one of the round rods 3. The tooth surface of the gear 617 meshes with the tooth block 609. The inner wall of the gear 617 is inserted into the rod 613. A hole 618 is opened on one side surface of the gear 617. The cross-sectional dimensions of the hole 618 are adapted to the rod 613. When one side of the mold part body 5 is ground and the other side needs to be ground, first pull the connecting block 614 so that the connecting block 614, along with the insert rod 613, moves away from the gear 617. Then rotate the adjusting rod 602 so that the adjusting rod 602 pushes the push block 604 to move. This causes the adjusting block 607 to move along with it, and the moving block 608 to be pushed upward. This causes the toothed block 609, along with the guide block 610, to move upward along the slide rail 611. The gear 617 is then rotated, causing the round rod 3 to rotate as well. The carrying frame 4 rotates until it flips 180 degrees. At this point, the insert rod 613 is aligned with the insertion hole 618. Release the connecting block 614, and the insert rod 613 is inserted into the insertion hole 618 under the action of the spring 616. This fixes the carrying frame 4, and then grinding can continue. Several friction grooves 603 are evenly distributed on the arc surface of one end of the adjusting rod 602.

A pull ring 615 is fixedly connected to the arc surface of the connecting block 614. The pull ring 615 has a circular cross-section. The connecting block 614 can be pulled using the pull ring 615, making it more convenient and faster.

An auxiliary pad 75 is fixedly connected to the lower surface of the pressing rod 74. The lower surface of the auxiliary pad 75 abuts against the surface of the mold part body 5. The auxiliary pad 75 is a rubber pad. When it is necessary to fix the mold part body 5, first place the mold part body 5 into the inner wall of the carrying frame 4, then rotate the connecting frame 73, causing the connecting frame 73 to rotate with the rotating rod 72, while simultaneously moving the connecting frame 73 downwards, until the pressing rod 74 on the connecting frame 73 can press the mold part body 5. Then rotate the pressing rod 74, causing the pressing rod 74 to move downwards with the auxiliary pad 75, until the auxiliary pad 75 abuts against the mold part body 5, thus fixing the mold part body 5. When the mold part body 5 is finished grinding and needs to be removed, rotate the pressing rod 74 in the opposite direction, causing the pressing rod 74 to move upwards with the auxiliary pad 75 to a certain position, then rotate the connecting frame 73, causing the connecting frame 73 to rotate with the rotating rod 72, while simultaneously moving upwards, until it rotates to a certain position, making it easier to remove the mold part body 5. A handle 76 is fixedly connected to one end of the pressing rod 74, and the handle 76 has a circular cross-section. The pressing rod 74 can be rotated with the help of the handle 76, achieving a more convenient operation. The handle 76 has several anti-slip textures 77 evenly distributed on its arc surface. The anti-slip textures 77 increase friction, making it easier for the operator to rotate the pressing rod 74 using the handle 76.

[0033] The working principle of the mold part surface grinding device provided by this utility model is as follows: When grinding the mold part body 5, the mold part body 5 needs to be positioned first, and then one side of the mold part body 5 is ground. After grinding, the mold part body 5 needs to be flipped over and the other side of the mold part body 5 is ground. First, the connecting block 614 is pulled by the pull ring 615, so that the connecting block 614 carries the insert rod 613 away from the gear 617. Then, the adjusting rod 602 is rotated, so that the adjusting rod 602 pushes the push block 604 to move. The push block 604 carries the slider 605 along the slide groove 606. As the moving block 608 moves upward, the adjusting block 607 moves along with the pushing block 604, and the moving block 608 is pushed upward by the adjusting block 607, causing the toothed block 609 to move upward along the slide rail 611 with the guide block 610. The gear 617 is rotated by the toothed block 609, and the round rod 3 also rotates, causing the carrying frame 4 to rotate until the carrying frame 4 is rotated 180 degrees. At this time, the insertion rod 613 is exactly aligned with the insertion hole 618. The connecting block 614 is released, and the insertion rod 613 is inserted into the insertion hole 618 under the action of the spring 616. In this way, the carrying frame 4 is fixed, and then the other side of the mold part body 5 can continue to be ground.

[0034] Before grinding the mold part body 5, it is necessary to position the mold part body 5. First, place the mold part body 5 into the inner wall of the carrying frame 4, and then rotate the connecting frame 73 so that the connecting frame 73 rotates with the rotating rod 72. At the same time, the connecting frame 73 moves downward until the pressing rod 74 on the connecting frame 73 can press the mold part body 5. Then, use the handle 76 to rotate the pressing rod 74 so that the pressing rod 74 moves downward with the auxiliary pad 75 until the auxiliary pad 75 abuts against the mold part body 5. In this way, the mold part body 5 can be fixed. When the mold part body 5 is finished grinding and needs to be removed, use the handle 76 to rotate the pressing rod 74 in the opposite direction so that the pressing rod 74 moves upward with the auxiliary pad 75 to a certain position. Then, rotate the connecting frame 73 so that the connecting frame 73 rotates with the rotating rod 72 and moves upward until it rotates to a certain position, making it easy to remove the mold part body 5. Then, remove the mold part body 5.
