Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a horizontal opening and closing mold for the production of grinding wheels and grinding heads. Background Technology

[0002] Grinding wheels are made by mixing abrasive and binder in an appropriate ratio, followed by pressing, drying, and sintering. After sintering, a series of processes are required, including turning, static balancing, hardness testing, and maximum working speed testing, to ensure the quality of the grinding wheel. A pressing mold is needed in the production process.

[0003] The existing pressing molds for grinding wheels are generally vertical structures, which include an upper mold and a lower mold that can move up and down. In actual pressing work, it is inconvenient to load and unload the forming grinding wheel, resulting in low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontal opening and closing mold for the production of grinding wheels and grinding heads, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a horizontal opening and closing mold for producing grinding wheel heads, comprising a base, a horizontal opening and closing mold body horizontally disposed at the top of the base, and a feeding mechanism disposed at the top of the horizontal opening and closing mold body for feeding material onto the horizontal opening and closing mold body. A pre-pressing mechanism is disposed above the horizontal opening and closing mold body, and an upper mold assembly is disposed on one side of the pre-pressing mechanism for extruding the top of the forming cavity of the horizontal opening and closing mold body. A linear adjustment mechanism for adjusting the horizontal position of the horizontal opening and closing mold body is disposed on one side of the top of the base for pushing the horizontal opening and closing mold body to move directly below the pre-pressing mechanism or the upper mold assembly. A feeding mechanism is disposed at the bottom of the base.

[0006] The upper mold assembly includes a second mounting plate that is slidably mounted up and down via a fourth linear drive component, a number of pressure rods fixed to the bottom end of the second mounting plate via a mounting base, and a number of core rods disposed at the center of the pressure rods. The pressure rods are used to press the material inside the molding cavity of the horizontal opening and closing mold body downwards, and the core rods are used to form a mounting groove at the top of the molded workpiece.

[0007] Each of the pressure rods has a sliding hole through the middle that matches the core rod. Each core rod is slidably disposed inside the sliding hole in the middle of the pressure rod, and the top of the core rod is provided with a lifting mechanism that drives each core rod to slide up and down synchronously.

[0008] The mounting base has a horizontal through hole in the middle that runs through both sides of the mounting base. The lifting mechanism includes a connecting plate that is horizontally arranged inside the through hole, and both ends of the connecting plate extend to the outside of the through hole. The connecting plate outside the through hole is provided with a fifth linear drive member that drives it to slide up and down inside the through hole of the mounting base. The top ends of the core rods extend into the through hole and are fixedly connected to the connecting plate.

[0009] Furthermore, the horizontal opening and closing mold body includes a first mold and a second mold with horizontal openings opposite each other, and a first linear drive component for adjusting the distance between the first mold and the second mold. The first mold and the second mold are both horizontally slidably connected to the base. The first mold and the second mold are spliced ​​together to form a forming cavity with an opening at the top. The forming cavity has the same shape as the grinding wheel head.

[0010] Furthermore, the molding cavity is provided with multiple cavities.

[0011] Furthermore, the feeding mechanism includes a base plate horizontally disposed on one side of the top of the horizontal opening and closing mold body and a storage cavity slidably disposed on the top of the base plate via a second linear drive component. The top of the storage cavity is provided with a feeding port, and the bottom of the storage cavity is provided with a discharge port, which is used to push the material into the forming cavity of the first mold and the second mold when the first mold and the second mold are closed.

[0012] Furthermore, the pre-compression mechanism includes a first mounting plate that is slidably mounted up and down via a third linear drive member and a plurality of top rods mounted at the bottom end of the first mounting plate.

[0013] Furthermore, a discharge port is provided through one side of the top of the base, and the unloading mechanism includes a discharge plate inclinedly installed at the bottom of the discharge port and a top-loading module for separating the formed grinding wheel head from the horizontal opening and closing mold body.

[0014] Furthermore, the top material module includes a sixth linear drive unit vertically mounted on the bottom of the base via a mounting bracket and a connecting bracket fixed to the output end of the sixth linear drive unit. The connecting bracket passes through the discharge plate and extends to the top of the discharge plate, and a guide plate is obliquely mounted on the top of the connecting bracket.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the horizontal opening and closing mold used for the production of grinding wheel heads.

[0016] By setting up a first mold and a second mold that are horizontally opposite each other, and setting up a feeding mechanism and a discharging mechanism at the upper and lower ends of the horizontal opening and closing mold body, it is convenient to feed the material into the forming cavity. After extrusion is completed, the first mold and the second mold can be separated and the material can be discharged from the bottom. Multiple grinding wheels can be processed at one time, with high working efficiency. At the same time, different molds can be replaced to produce different types of grinding wheels.

[0017] By setting a pre-compression mechanism, pre-compression can be performed before the upper mold assembly is extruded, making the material inside the molding cavity more uniform and compact. The upper mold assembly includes a pressure rod and a core rod that are movably connected. When unloading after extrusion, the core rod can be pulled out in advance, and then the pressure rod can be pulled out to avoid the edge of the mounting groove at the top of the grinding wheel head being deformed, thus improving the product molding quality.

[0029] Please see Figure 1-8An embodiment of the present invention provides a horizontal opening and closing mold for producing grinding wheel heads, comprising a base 1, a horizontal opening and closing mold body 2 horizontally disposed at the top of the base 1, and a feeding mechanism 3 disposed at the top of the horizontal opening and closing mold body 2 for feeding material into the horizontal opening and closing mold body 2. The horizontal opening and closing mold body 2 includes a first mold 201 and a second mold 202 with horizontal openings facing each other, and a first linear drive component 203 for adjusting the distance between the first mold 201 and the second mold 202. The first linear drive component 203 can be any one of a hydraulic cylinder, a pneumatic cylinder, a lead screw motor, etc. In this embodiment, it is set as a hydraulic cylinder, which is fixed in the second mold 202 away from the first mold 201. On one side, its output end is fixedly connected to the first mold 201. The distance between the first mold 201 and the second mold 202 is adjusted by the extension and retraction of the hydraulic cylinder to achieve mold closing and opening. Both the first mold 201 and the second mold 202 are horizontally slidably connected to the base 1 via slide rails. Specifically, two slide rails are provided along the mold closing and opening directions of the first mold 201 and the second mold 202, serving as guides when the first mold 201 and the second mold 202 slide horizontally synchronously or separately. The first mold 201 and the second mold 202 are joined to form a forming cavity with an open top. The forming cavity has the same shape as the grinding wheel head. The shape of the grinding wheel head is shown in the attached figure. Figure 8 The first mold 201 and the second mold 202 are in the shape of a bullet. The opposite side of the first mold 201 and the second mold 202 is half a bullet shape. In actual production, different molds can be replaced as needed to produce different grinding wheels. The opposite side of the first mold 201 and the second mold 202 is provided with mutually cooperating guide pillars and guide grooves to improve the mold closing accuracy of the two.

[0030] There are multiple molding cavities. In this embodiment, there are three molding cavities. During extrusion molding, three products can be processed at once, which improves work efficiency. Other numbers can also be set as needed.

[0031] The feeding mechanism 3 includes a base plate 301 horizontally disposed on one side of the top of the horizontal opening and closing mold body 2, and a storage cavity 302 slidably disposed on the top of the base plate 301 via a second linear drive 303. The top of the storage cavity 302 has an inlet, and the bottom of the storage cavity 302 has a through outlet. When the storage cavity 302 separates from the base plate 301, it can discharge material downwards. This is used to push the material into the forming cavity of the first mold 201 and the second mold 202 when the first mold 201 and the second mold 202 are closed. The base plate 301 is specifically fixed to one side of the top of the first mold 201, and the top of the base plate 301... The end is flush with the top of the first mold 201, and the base plate 301 can move horizontally synchronously with the first mold 201. The second linear drive 303 can be any one of a hydraulic cylinder, a pneumatic cylinder, a lead screw motor, etc. In this embodiment, the second linear drive 303 is a horizontally arranged hydraulic cylinder. The hydraulic cylinder is installed on the top of the base 1 through a bracket. The output end of the hydraulic cylinder is fixedly connected to the storage cavity 302. After the mixed raw material is added into the storage cavity 302 through the feed port, the storage cavity 302 is driven to move to the top of the molding cavity. After the molding cavity is filled, the storage cavity 302 is reset, and the excess material is scraped off and taken away.

[0032] Please see Figure 3 A pre-pressing mechanism 4 is provided above the horizontal opening and closing mold body 2. The pre-pressing mechanism 4 includes a first mounting plate 402 that is slidably mounted up and down via a third linear drive 401 and several ejector rods 403 located at the bottom of the first mounting plate 402. Specifically, a fixed top plate 8 is mounted on the top of the base 1 via four guide posts. The third linear drive 401 can be any of a hydraulic cylinder, pneumatic cylinder, or lead screw motor. In this embodiment, it is set as a hydraulic cylinder. The hydraulic cylinder is mounted on the fixed top plate 8, and its output end is downward and fixedly connected to the first mounting plate 402. By extending and retracting the hydraulic cylinder, the first mounting plate 402 is moved up and down. Guide rods are vertically provided on both sides of the top of the first mounting plate 402. The fixed top plate 8 is provided with through holes that match the guide rods to improve the stability of the up and down movement of the first mounting plate 402. In this embodiment, there are three ejector rods 403. The ejector rods 403 are relatively long and extend to the bottom of the molding cavity to compact the material inside the molding cavity, ensuring uniformity from top to bottom and preventing the material from clogging inside the molding cavity and affecting the molding of the workpiece.

[0033] One side of the pre-compression mechanism 4 is provided with an upper mold assembly 5 for extruding the top of the molding cavity of the horizontal opening and closing mold body 2. The upper mold assembly 5 includes a second mounting plate 501 that is slidably mounted up and down via a fourth linear drive member 502, a plurality of pressure rods 504 fixed to the bottom of the second mounting plate 501 via a mounting base 503, and a plurality of core rods 505 disposed at the center of the pressure rods 504. The pressure rods 504 are used to compress the material inside the molding cavity of the horizontal opening and closing mold body 2 downwards, and the core rods 504 are used to form a mounting groove at the top of the molded workpiece. (Refer to the attached drawing.) Figure 8In the middle of the top of the grinding wheel head, there is a groove for mounting the rotating shaft. The fourth linear drive component 502 can be any one of a hydraulic cylinder, air cylinder, or lead screw motor. In this embodiment, it is set as a hydraulic cylinder. The hydraulic cylinder is fixedly connected to the fixed top plate 8. Its output end is vertically downward and fixedly connected to the second mounting plate 501. The four corners of the second mounting plate 501 are provided with sliding holes that match the guide columns, so that the second mounting plate 501 can slide up and down stably. There are three pressure rods 504. Specifically, they are cylindrical structures with the same size as the top of the forming cavity. The core rod 505 is a cylindrical structure set on the same axis as the pressure rod 504.

[0034] In this embodiment, each pressure rod 504 has a sliding hole through its center that matches the core rod 505. The core rods 505 are slidably disposed inside the sliding holes in the center of the pressure rod 504. The top of each core rod 505 is provided with a lifting mechanism 506 that drives each core rod 505 to slide up and down synchronously. During extrusion molding, the bottom end of the core rod 505 is located below the pressure rod 504. During discharge, the lifting mechanism 506 drives the core rod 505 to rise first, and then drives the pressure rod 504 to rise. This can prevent the core rod 505 from deforming the edge of the center hole of the grinding wheel head, thereby improving the workpiece molding quality.

[0035] The mounting base 503 has a horizontal through hole in the middle, penetrating both sides of the mounting base 503. The lifting mechanism 506 includes a connecting plate 5061 horizontally disposed inside the through hole, and both ends of the connecting plate 5061 extend to the outside of the through hole. The connecting plate 5061 outside the through hole is provided with a fifth linear drive member 5062 that drives it to slide up and down inside the through hole of the mounting base 503. The top end of the core rod 505 extends into the through hole and is fixedly connected to the connecting plate 5061. The fifth linear drive member 5062 can be any one of a hydraulic cylinder, air cylinder, screw motor, etc. In this embodiment, it is set as a hydraulic cylinder, and there are two hydraulic cylinders, which are fixed on both sides of the top end of the second mounting plate 501 respectively. Their output ends extend to the bottom end of the second mounting plate 501 and are fixedly connected to the connecting plate 5061. By extending and retracting the hydraulic cylinder, the connecting plate 5061 and the core rod 505 move up and down.

[0036] A linear adjustment mechanism 7 for adjusting the horizontal position of the horizontal opening and closing mold body 2 is provided on one side of the top of the base 1. In this embodiment, the linear adjustment mechanism 7 includes a bracket vertically fixed to one side of the top of the base 1 and a hydraulic cylinder horizontally mounted on the bracket. Its output end is fixedly connected to the first mold 201. The extension and retraction direction of the hydraulic cylinder is opposite to the extension and retraction direction of the first linear drive 203. It is used to push the horizontal opening and closing mold body 2 to move directly below the pre-pressing mechanism 4 or the upper mold assembly 5 to pre-press or formally extrude the material inside the molding cavity. The bottom end of the base 1 is provided with The unloading mechanism 6 has an outlet 101 extending through one side of the top of the base 1. In this embodiment, the outlet 101 is located directly below the upper mold assembly 5. The unloading mechanism 6 includes an outlet plate 601 inclinedly installed at the bottom of the outlet 101 and a top-loading module for pushing the grinding wheel head for forming, which is separated from the horizontal opening and closing mold body 2. The top-loading module includes a sixth linear drive 603 vertically installed at the bottom of the base 1 via a mounting bracket 602 and a connecting bracket 605 fixed to the output end of the sixth linear drive 603. The connecting bracket 605 extends through the outlet plate 601. 1. Extending to the top of the discharge plate 601, the top of the connecting bracket 605 is inclinedly equipped with a guide plate 604. The sixth linear drive component 603 can be any one of a hydraulic cylinder, air cylinder, or lead screw motor. In this embodiment, it is set as a hydraulic cylinder. The mounting bracket 602 includes a horizontally arranged cross plate and two slide rods fixed on both sides of the top of the cross plate. The top of the slide rods is fixedly connected to the base 1. The hydraulic cylinder is fixed at the bottom of the cross plate, and its output end extends to the top of the cross plate. The connecting bracket 605 includes a cross plate fixed to the output end of the hydraulic cylinder and two vertical rods fixed to the top of the cross plate. The material plate 601 has through holes on both sides to accommodate the extension of the upright to the top. The two sides of the horizontal plate are slidably connected to the sliding rods on both sides of the mounting bracket 602, which improves the stability of the connecting bracket 605 when moving up and down. During operation, the first mold 201 and the second mold 202 separate, and the distance between them is just enough to allow the guide plate 604 to pass through. After the guide plate 604 lifts the workpiece to demold, it moves down and separates from the first mold 201 and the second mold 202. Under the action of gravity, it is discharged downward through the discharge port 101 and the discharge plate 601 to avoid the workpiece being bumped and damaged.

[0037] Working principle: First, the first mold 201 and the second mold 202 close, and powder raw materials are added into the storage cavity 302. The second linear drive 303 pushes the storage cavity 302 to the top of the first mold 201 and the second mold 202, causing the material inside the storage cavity 302 to fall into the molding cavity. Then, the storage cavity 302 resets, and the horizontal opening and closing mold body 2 is moved directly below the pre-pressing mechanism 4 by the linear adjustment mechanism 7. The third linear drive 401 extends, pushing each ejector rod 403 to be inserted into the molding cavity of each of the horizontal opening and closing mold body 2 simultaneously for pre-pressing. The ejector rod 403 is relatively long, extending to the bottom of the molding cavity, compacting the material inside the molding cavity evenly. Then, the third linear drive 401 drives the ejector rod 403 to reset upwards, and the horizontal opening and closing mold body 2 is moved directly below the upper mold assembly 5 by the linear adjustment mechanism 7. At this time, the bottom end of the core rod 505 is located below the pressure rod 504. The fourth linear drive 50 2. The pressure rod 504 and the core rod 505 move downwards synchronously. The pressure rod 504 presses the material inside the forming cavity downwards and compacts it. The core rod 505 is inserted into the top of the forming cavity, forming a cylindrical groove in the middle of the workpiece for the subsequent installation of the grinding wheel spindle. After extrusion molding, the fifth linear drive 5062 retracts, driving each core rod 505 to rise in advance. Since the pressure rod 504 is pressed against the top of the workpiece, the edge of the core rod 505 forming groove will not be deformed. Then, the fourth linear drive 502 retracts, driving the pressure rod 504 to rise. The first linear drive 203 extends, separating the first mold 201 and the second mold 202. At this time, the horizontal opening and closing mold body 2 is located directly above the discharge port 101. The sixth linear drive 603 extends, pushing the guide plate 604 to rise and pushing the material to move upwards and separate from the forming cavity of the horizontal opening and closing mold body 2. The sixth linear drive 603 then slowly descends, and the material falls to the top of the discharge plate 601 for unloading.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
