Technical Field

[0001] This utility model belongs to the field of resin grinding wheel molding technology, specifically relating to a double-table resin grinding wheel molding machine. Background Technology

[0002] The production process of resin grinding wheels requires adding powder and glass fiber or other reinforcing materials into a mold, and then molding it under high pressure using a press.

[0003] For example, CN 218856672 U discloses a resin grinding wheel molding machine, which applies pressure to powder through a pressure device to mold the powder; automatically feeds the powder quantitatively and completes the scraping process through a feeding device, reducing the labor intensity of operators and improving the automation level of the equipment; the rotating device itself carries multiple groups of powder and transports the powder to different processing areas, and the structure of the rotating device itself makes it easier to remove the processed resin grinding wheel, improving the practicality of the equipment; the lifting device changes the height of the rotating device and limits its own stroke to prevent damage to other parts of the equipment during the lifting process, improving the practicality of the equipment; it includes a worktable, a pressure device, a positioning device, and a buffer device, all of which are installed on the worktable; it also includes a worktable, a pressure device, two sets of feeding devices, a rotating device, and a lifting device;

[0004] In the actual use of the above case, the machine needs to be stopped to remove and reload the resin grinding wheel after it has been formed, which greatly reduces the machine's working efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a double-table resin grinding wheel molding machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-table resin grinding wheel molding machine, including a frame, with two symmetrically arranged molding stations on the top of the frame, a mold body placed inside the molding station, electric slide rails fixedly connected to both sides of the frame, a sliding frame slidably connected to the outside of the electric slide rails, an upper mold provided at the top of the inner cavity of the sliding frame, and buffer components provided on both sides of each molding station.

[0007] In a preferred embodiment, an electric lifting rod is fixedly connected to the top of the sliding frame, and the upper mold is disposed at the bottom end of the electric lifting rod.

[0008] In a preferred embodiment, side plates are fixedly connected to both sides of the upper mold, and an extrusion plate is fixedly connected to the bottom of the side plates.

[0009] In a preferred embodiment, the buffer assembly includes “L”-shaped auxiliary grooves symmetrically arranged on both sides of the molding station. Each auxiliary groove has guide protrusions on both sides of its inner cavity, and two guide protrusions are slidably connected to a sliding fixing frame with a right-angled trapezoidal cross-section.

[0010] In a preferred embodiment, both sides of the sliding fixing frame are fixedly connected to fixing blocks, and the interior of each fixing block is slidably connected to a sliding column.

[0011] In a preferred embodiment, the sliding fixing frame has an arc-shaped limiting part on the side facing the mold body, and the bottom of both sides of the mold body is provided with limiting grooves that are adapted to the sliding fixing frame.

[0012] In a preferred embodiment, one end of the sliding column is fixedly connected to the auxiliary groove, and the other end of the sliding column is fixedly connected to the fixed block with a spring sleeved on the outside of the sliding column.

[0013] In a preferred embodiment, the extrusion plate is located directly above the auxiliary groove, and the bottom of the extrusion plate is provided with an inclined surface that fits against the inclined side of the right-angled trapezoidal sliding fixing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This dual-worktable resin grinding wheel molding machine features a dual-worktable structure with two symmetrical molding stations on the top of the frame. Combined with electric slide rails and sliding frames, this allows the other molding station to simultaneously perform material loading and unloading operations while resin grinding wheel molding is being performed at one station. This avoids the problem of traditional single-worktable equipment requiring machine stoppage for material loading and unloading, greatly improving the machine's working efficiency.

[0016] This dual-table resin grinding wheel molding machine, by setting up a buffer component, ensures that when the upper mold is pressed down during the molding process, the extrusion plate will first contact the sliding fixed frame. Since the bottom slope of the extrusion plate is in contact with the slope of the sliding fixed frame, it will push the sliding fixed frame to slide along the guide protrusion. At the same time, the fixed blocks on both sides of the sliding fixed frame slide on the sliding column and compress the spring, which plays a buffering role, reduces the impact force on the mold body and equipment during molding, protects the equipment, and extends the service life of the equipment.

[0017] This dual-table resin grinding wheel molding machine, through the matching of the arc-shaped limiting part of the sliding fixed frame with the limiting grooves on both sides of the bottom of the mold body, can limit and fix the mold body, ensuring the stability of the mold body during the molding process and improving the molding quality.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-4 This utility model provides a double-worktable resin grinding wheel molding machine, including a frame 1. The top of the frame 1 is provided with two symmetrically arranged molding stations 101. The mold body 7 is placed inside the molding station 101. Electric slide rails 2 are fixedly connected to both sides of the frame 1. A sliding frame 3 is slidably connected to the outside of the electric slide rails 2. An upper mold 5 is provided at the top of the inner cavity of the sliding frame 3. An electric lifting rod 4 is fixedly connected to the top of the sliding frame 3. The upper mold 5 is located at the bottom end of the electric lifting rod 4.

[0026] The sliding frame 3 is located above one of the molding stations 101, where the mold body 7 has been placed and preparations such as adding powder and reinforcing materials have been completed; the other molding station 101 is in an idle state and can be used for material picking and loading operations. The electric lifting rod 4 is activated, and the electric lifting rod 4 pushes the upper mold 5 downward. The upper mold 5 applies pressure to the mold body 7 placed in the molding station 101, so that the powder is formed into a resin grinding wheel in the mold body 7.

[0027] After the resin grinding wheel in the molding station 101 is molded, the electric lifting rod 4 drives the upper mold 5 to rise and reset. Then, the electric slide rail 2 is activated, and the electric slide rail 2 drives the sliding frame 3 to slide along both sides of the frame 1, so that the sliding frame 3 moves above another molding station 101. During the process of the sliding frame 3 moving above another molding station 101, the molding station 101 that has been molded can perform material removal (removing the molded resin grinding wheel from the mold body 7) and material loading (adding new powder and reinforcing material to the mold body 7). When the sliding frame 3 moves into place, the electric lifting rod 4 is activated again, so that the upper mold 5 descends to perform molding operation on the mold body 7 in the molding station 101. This cycle is repeated to realize the alternating operation of the two molding stations 101.

[0028] By setting up two symmetrical molding stations 101 and using electric slide rail 2 to switch the sliding frame 3 between the two molding stations 101, when resin grinding wheel molding is being performed at one molding station 101, the other molding station 101 can simultaneously perform material picking and loading operations. This avoids the problem of traditional single-workbench equipment needing to stop for material picking and loading, greatly improving the machine's working efficiency and shortening the production cycle.

[0029] In this embodiment, each molding station 101 is provided with a buffer assembly on both sides. Side plates 6 are fixedly connected to both sides of the upper mold 5, and an extrusion plate 601 is fixedly connected to the bottom of the side plates 6. The buffer assembly includes symmetrically arranged "L"-shaped auxiliary grooves 102 on both sides of the molding station 101. Guide protrusions 103 are provided on both sides of the inner cavity of each auxiliary groove 102. A sliding fixing frame 104 with a right-angled trapezoidal cross-section is slidably connected to the outside of the two guide protrusions 103. Fixing blocks 105 are fixedly connected to both sides of the sliding fixing frame 104. The inner surfaces of the fixing blocks 105 slide... The sliding column 106 is dynamically connected, and the sliding fixing frame 104 is provided with an arc-shaped limiting part 1041 on the side facing the mold body 7. The bottom of both sides of the mold body 7 is provided with limiting grooves 701 that are adapted to the sliding fixing frame 104. One end of the sliding column 106 is fixedly connected to the auxiliary groove 102, and the other end of the sliding column 106 is fixedly connected to the fixing block 105 with a spring 107 sleeved on the outside of the sliding column 106. The extrusion plate 601 is located directly above the auxiliary groove 102, and the bottom of the extrusion plate 601 is provided with an inclined surface that fits against the inclined side of the right trapezoidal sliding fixing frame 104.

[0030] When the mold body 7 is placed in the molding station 101, during the placement process, the sliding fixing frame 104, under the action of the spring 107, will have its arc-shaped limiting part 1041 partially inserted into the limiting groove 701 at the bottom of both sides of the mold body 7, which will play a preliminary limiting role on the mold body 7 and prevent the mold body 7 from shaking randomly in the molding station 101.

[0031] When the electric lifting rod 4 pushes the upper mold 5 downward, the extrusion plate 601 fixed to the bottom of the side plates 6 on both sides of the upper mold 5 will also move downward. Since the extrusion plate 601 is located directly above the auxiliary groove 102 and its bottom is provided with an inclined surface that fits against the inclined side of the right trapezoidal sliding fixing frame 104, as the extrusion plate 601 continues to press down, its inclined surface will contact the inclined side of the sliding fixing frame 104 and generate an interaction force.

[0032] Under the interaction force between the inclined surface of the extrusion plate 601 and the inclined side of the sliding fixing frame 104, the sliding fixing frame 104 will slide along the guide protrusion 103 into the auxiliary groove 102. At the same time, the fixing blocks 105 on both sides of the sliding fixing frame 104 will slide on the sliding column 106 and compress the spring 107. After the spring 107 is compressed, it will generate a reverse elastic force, which plays a buffering role and gradually offsets the impact force generated when the upper die 5 is pressed down.

[0033] As the upper mold 5 continues to press down, after overcoming the elastic force of the spring 107, the upper mold 5 finally contacts the mold body 7 and applies pressure to the powder, causing the powder to be formed into a resin grinding wheel inside the mold body 7.

[0034] After the resin grinding wheel is formed, the electric lifting rod 4 drives the upper mold 5 to rise, and the extrusion plate 601 also rises. At this time, the sliding fixed frame 104 slides and resets along the guide protrusion 103 to the outside of the auxiliary groove 102 under the elastic force of the spring 107. The arc-shaped limiting part 1041 extends into the limiting groove 701 again to prepare for the next molding.

[0035] The buffer assembly effectively absorbs and releases the impact force generated when the upper mold 5 is pressed down through the compression and reset of the spring 107, reducing the impact on the mold body 7, molding station 101, and the entire equipment. This prevents damage to the equipment due to long-term exposure to large impact forces and extends the service life of the equipment. The arc-shaped limiting part 1041 of the sliding fixing frame 104 is adapted to the limiting grooves 701 on both sides of the bottom of the mold body 7, which can reliably limit and fix the mold body 7, ensuring that the mold body 7 will not shift during the molding process. This improves the molding quality of the resin grinding wheel and reduces the defect rate caused by mold shaking. The buffer assembly composed of the "L"-shaped auxiliary groove 102, guide protrusion 103, sliding fixing frame 104, fixing block 105, sliding column 106, and spring 107 has a reasonable structure and the components fit tightly together. This ensures that the sliding fixing frame 104 runs smoothly during the sliding process without jamming or offset, further improving the stability and reliability of the equipment.

[0036] The working principle and usage process of this utility model are as follows: First, the sliding frame 3 is located above one of the molding stations 101. The mold body 7 is placed in the molding station 101. During the placement process, the sliding fixed frame 104, under the action of the spring 107, will have its arc-shaped limiting part 1041 partially inserted into the limiting groove 701 at the bottom of both sides of the mold body 7, which will play a preliminary limiting role on the mold body 7, prevent the mold body 7 from shaking randomly in the molding station 101, and complete the preparation work such as adding powder and reinforcing materials.

[0037] Another molding station 101 is in an idle state and can be used for material picking and loading operations. The electric lifting rod 4 is activated, and the electric lifting rod 4 pushes the upper mold 5 to move downward. The upper mold 5 applies pressure to the mold body 7 placed in the molding station 101.

[0038] When the electric lifting rod 4 pushes the upper mold 5 downward, the extrusion plate 601 fixed to the bottom of the side plates 6 on both sides of the upper mold 5 will also move downward. Since the extrusion plate 601 is located directly above the auxiliary groove 102 and its bottom is provided with an inclined surface that fits against the inclined side of the right trapezoidal sliding fixing frame 104, as the extrusion plate 601 continues to press down, its inclined surface will contact the inclined side of the sliding fixing frame 104 and generate an interaction force.

[0039] Under the interaction force between the inclined surface of the extrusion plate 601 and the inclined side of the sliding fixing frame 104, the sliding fixing frame 104 will slide along the guide protrusion 103 into the auxiliary groove 102. At the same time, the fixing blocks 105 on both sides of the sliding fixing frame 104 will slide on the sliding column 106 and compress the spring 107. After the spring 107 is compressed, it will generate a reverse elastic force, which plays a buffering role and gradually offsets the impact force generated when the upper die 5 is pressed down.

[0040] As the upper mold 5 continues to press down, after overcoming the elastic force of the spring 107, the upper mold 5 finally contacts the mold body 7 and applies pressure to the powder, causing the powder to be formed into a resin grinding wheel inside the mold body 7.

[0041] After the resin grinding wheel is formed, the electric lifting rod 4 drives the upper mold 5 to rise, and the extrusion plate 601 also rises. At this time, the sliding fixed frame 104 slides and resets along the guide protrusion 103 to the outside of the auxiliary groove 102 under the elastic force of the spring 107. The arc-shaped limiting part 1041 extends into the limiting groove 701 again to prepare for the next molding.

[0042] After the resin grinding wheel in the molding station 101 is molded, the electric lifting rod 4 drives the upper mold 5 to rise and reset. Then, the electric slide rail 2 is activated, and the electric slide rail 2 drives the sliding frame 3 to slide along both sides of the frame 1, so that the sliding frame 3 moves above another molding station 101. During the process of the sliding frame 3 moving above another molding station 101, the molding station 101 that has been molded can perform material removal (removing the molded resin grinding wheel from the mold body 7) and material loading (adding new powder and reinforcing material to the mold body 7). When the sliding frame 3 moves into place, the electric lifting rod 4 is activated again, so that the upper mold 5 descends to perform molding operation on the mold body 7 in the molding station 101. This cycle is repeated to realize the alternating operation of the two molding stations 101.

[0043] In the above scheme, the following points need to be explained: The electric slide rail 2 in this application belongs to the existing electric slide rail products of WON linear guide rail M series, and the specific structure and driving principle of the electric slide rail 2 are existing publicly available technologies, which will not be described in detail here.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
