Description

Technical Field

[0001] This invention relates to a heat-insulating and heating riser forming device, specifically a heat-insulating and heating riser forming equipment and method, belonging to the field of casting equipment technology. Background Technology

[0002] A riser is an additional part attached to the top or side of a casting to prevent defects. It also serves to vent air and collect slag.

[0003] A search revealed Chinese patent CN101927323A, which discloses a heat-insulating and heating riser forming device. This device includes a pot body, a slurry mixing device, a riser mold, a mold flipping device, a pneumatic hollow reducer, a vacuum settling tank, rollers, and a roller adjusting device. The riser mold's evacuation port is sealed and fixedly connected to the hollow output shaft of the pneumatic hollow reducer motor. The flipping arm of the mold flipping device is fixed to the housing of the pneumatic hollow reducer motor. The vacuum settling tank's inlet is connected to the center hole of the pneumatic hollow reducer via a flexible hose, thus connecting the vacuum settling tank's inlet to the riser mold's evacuation port.

[0017] The forming method of the above-mentioned heat-insulating and heating riser forming equipment includes the following forming steps:

[0018] S. Expanded perlite, quartz sand, aluminum powder, magnesium powder, iron oxide powder, potassium nitrate, sodium chloride, alkaline phenolic resin, organic ester and coupling agent are poured into the raw slurry mixing tank in proportion, and the raw materials are fully mixed and stirred by the stirring fan blades.

[0019] S. During pouring, the upper mold and the lower mold are tightly fitted together. The upper mold and the lower mold are lowered and submerged into the mixed slurry in the slurry mixing tank by the first telescopic cylinder, and the raw material is poured into the mold.

[0020] S. After the vacuum pump evacuates the riser in the mold after pouring, the mold rises away from the surface of the original slurry pool. The scraper moves to scrape off the original slurry attached to the top of the upper mold. When the scraper moves to the position of the placement block, the horizontal scraper moves to scrape off the original slurry at the front end of the scraper.

[0021] S.

With the start of the drive telescopic cylinder, the placement platform moves out of the top of the raw pulp mixing tank.

[0023] The present invention has the following beneficial effects:

[0024] 1. The residual slurry in the mold is scraped off by the scraping device, and the outside of the riser is smoothed by the synchronous rotation of the "7" shaped smoothing knife, which eliminates surface defects, solves the problem of rough finished products in traditional equipment, and improves the surface smoothness and dimensional accuracy of the riser.

[0025] 2. A combined demolding process of "mold flipping + hammering device" is adopted. The synchronous motor drives the hammering rod to repeatedly strike the lower mold, breaking the adhesion between the riser and the mold, shortening the demolding time, and avoiding the low efficiency problem of demolding by gravity alone.

[0026] 3. All components are linked by telescopic cylinders and motors to automate processes such as raw material mixing, pouring, and demolding, reducing manual intervention, lowering operational difficulty and error, ensuring batch quality consistency, and saving labor costs;

[0027] 4. The mixing fan blades ensure uniform mixing of raw materials, the automatic removal of finished products from the placement table reduces process interruptions, and the self-cleaning scraper and reinforced component design reduce equipment wear, extend service life, and maintain continuous operation of the production line.

The non-acting end of the first telescopic cylinder 201 is connected to the top of the inner part of the outer frame support 102. The acting end of the first telescopic cylinder 201 is provided with a telescopic rod 202. A fixed sleeve 203 is provided in the middle of the telescopic rod 202. Two movable rods 204 are provided inside the pulp mixing tank 1. The top of the movable rod 204 is fixedly connected to the outer frame support 102.

A second telescopic cylinder 207 is provided in the middle of the crossbar 206. A connecting tripod 210 is provided on the acting end of the second telescopic cylinder 207. The bottom two sides of the connecting tripod 210 are fixedly connected to the two sides of the upper mold 211.

[0046] A transverse telescopic cylinder 501 is provided at the end of the scraper 502 away from the original pulp mixing tank 1, a moving groove 504 is provided at the bottom end of the placement block 503, a threaded block 507 is provided on the lead screw 505, an actuator motor 506 is provided at one end of the lead screw 505, the threaded block 507 is fixedly connected to the transverse scraper 508, and the transverse scraper 508 is arranged in an "n" shape.

[0047] The bottom of the pulp mixing tank 1 near the placement block 503 is provided with ground rails 605 on both sides. The top of the ground rail 605 is provided with a placement platform 6. The top of the placement platform 6 is provided with a placement plate 602. The ground rail 605 is provided with a drive telescopic cylinder 604. The end of the placement plate 602 away from the pulp mixing tank 1 is provided with a handle 603. The bottom of the placement plate 602 is provided with slots 601 on both sides.

[0048] The bottom of the raw slurry mixing tank 1 is equipped with a stirring fan blade 101. A forward and reverse motor 4 is provided on one side of the lower mold 209. The forward and reverse motor 4 is located at the bottom of the telescopic rod 202. A vacuum pipe 401 is provided on one side of the lower mold 209. One end of the vacuum pipe 401 is connected to a vacuum pump 402.

[0049] In this embodiment, it should be noted that when the heat-insulating and heating riser is being formed, the raw materials are first poured into the slurry mixing tank 1 and thoroughly stirred by the stirring fan blade 101.

[0050] The telescopic rod 202 of the first telescopic cylinder 201 is connected to both sides of the lower mold 209. When processing the heat-insulating heating riser, the upper mold 211 and the lower mold 209 are tightly fitted together. The upper and lower molds are moved down by the extension of the first telescopic rod 201 until they are submerged in the raw slurry in the raw slurry mixing tank 1 to achieve pouring. At the same time as pouring, the vacuum pump 402 is started and the raw slurry poured into the mold is evacuated through the evacuation pipe 401.

[0051] After the upper mold 11 is removed from the surface of the original slurry, the transverse telescopic cylinder 501 is activated to drive the scraper 502 to move. The scraper 502 scrapes the original slurry attached to the top of the upper mold 211. When the scraper 502 moves to the position of the placement block 503, the actuator motor 506 is activated to drive the lead screw 505 to rotate. The threaded block 507, which is threadedly connected to the lead screw 505, moves on the lead screw 505, driving the transverse scraper 508 to move left and right, scraping off the original slurry attached to the front end of the scraper 502, thus achieving self-cleaning of the scraper 502.

[0052] When the scraper 502 is reset, the second telescopic cylinder 207 is activated to drive the connecting tripod 210 to rise, which in turn drives the upper mold 211 to rise and move out of the lower mold 209, exposing the riser material poured at the top of the lower mold 209.

[0053] The third telescopic cylinder 303 is activated, causing the lifting plate 304 to descend. At this time, multiple smoothing blades 311 located at the bottom of the lifting plate 304 pass through the through hole of the upper mold 211 to the outside of the riser material. The drive motor 305 is activated, causing the first gear disk 306 and the second gear disk 307 to rotate. At this time, the rotating gear 308 meshing with the first gear disk 305 and the connecting gear 309 meshing with the second gear disk 306 rotate. Therefore, multiple rotating rods 310 rotate synchronously, and the smoothing blades 311 at the bottom are arranged in a "7" shape to smooth the outside of the riser material.

[0054] After smoothing is completed, the third telescopic cylinder 303 rises to reset the smoothing blade 311. At this time, the forward and reverse motor 4 located on one side of the lower mold 209 starts, causing the lower mold 209 to rotate 180°. Simultaneously, the drive telescopic cylinder 604 starts, moving the placement platform 6 towards the raw pulp mixing tank 1 until it reaches the bottom of the lower mold 209 at the placement plate 602 position. The synchronous motor 701 starts, driving the rotating rod 702 to rotate. At this time, the notched bevel gear 703 rotates. When the gear on the notched bevel gear 703 engages with the first bevel gear 704... During engagement, the first bevel gear 704 and the reciprocating rod 706 rotate clockwise. When the gear on the notched bevel gear 703 rotates to the position of the second bevel gear 705 and engages with it, the second bevel gear 705 and the reciprocating rod 706 rotate counterclockwise. Therefore, as the rotating rod 702 and the notched bevel gear 703 rotate continuously, the reciprocating rod 706 and the striking rod 707 reciprocate. The striking rod 707 continuously strikes the two sides of the top of the flipped lower mold 209, assisting the riser material to be demolded and fall onto the top of the placement plate 602.

[0055] The telescopic cylinder 604 is retracted, which moves the placement plate 602 and the riser material out of the raw slurry mixing tank 1.

[0056] Example 2:

[0057] Unlike Example 1, referring to Figure 1-10 This embodiment also has the following further features: the bottom end of the outer frame bracket 102 is provided with two fixed rods 301, the bottom end of the two fixed rods 301 is provided with a horizontal plate 302, the middle of the horizontal plate 302 is provided with a third telescopic cylinder 303, the bottom end of the third telescopic cylinder 303 is fixedly connected to the top end of the lifting plate 304, the bottom ends of both sides of the horizontal rod 206 and located on the movable rod 204 are provided with sleeves 205, and support frames 208 are provided between the sleeves 205 and the fixed sleeves 203 and between the horizontal rod 206 and the fixed sleeves 203.

[0058] In this embodiment, it should be noted that: when the first telescopic cylinder 201 rises, the top end of the telescopic rod 202 retracts into the actuating end of the first telescopic cylinder 201. At this time, the lower mold 209 rises. Since the fixed sleeve 203 is fixed on the telescopic rod 202, and the sleeve 205 and the crossbar 206 are movably connected to the movable rod 204, and the support frame 208 connects the fixed sleeve 203 and the sleeve 205 and connects the fixed sleeve 203 and the crossbar 206 in a triangular connection shape, as the telescopic rod 202 moves up and down, it will synchronously drive the crossbar 206, i.e., the second telescopic cylinder 207 and the upper mold 211, to move up and down synchronously.

[0059] Example 3:

[0060] Reference Figure 1-10Compared to Embodiment 1 and Embodiment 2, in this embodiment: the first bevel gear 704 and the second bevel gear 705 are arranged opposite to each other, and a notched bevel gear 703 is provided at the bottom of the middle of the first bevel gear 704 and the second bevel gear 705. The gear on the notched bevel gear 703 meshes with the first bevel gear 704 and the second bevel gear 705. A rotating rod 702 is provided at the middle of the bottom of the notched bevel gear 703, and a synchronous motor 701 is provided at the bottom of the rotating rod 702.

[0061] In this embodiment, it should be noted that: when the synchronous motor 701 starts, it drives the rotating rod 702 to rotate. At this time, the notched bevel gear 703 rotates. When the gear on the notched bevel gear 703 meshes with the first bevel gear 704, it drives the first bevel gear 704 and the reciprocating rod 706 to rotate clockwise. When the gear on the notched bevel gear 703 rotates to the position of the second bevel gear 705 and meshes with it, the second bevel gear 705 and the reciprocating rod 706 rotate counterclockwise. Therefore, as the rotating rod 702 and the notched bevel gear 703 rotate continuously, the reciprocating rod 706 and the striking rod 707 reciprocate. The striking rod 707 continuously strikes the two sides of the top of the flipped lower mold 209, assisting the riser material to be demolded and fall onto the top of the placement plate 602.

[0062] The PLC controller with model number "S7-1200" is electrically connected to the first telescopic cylinder 201, the second telescopic cylinder 207, the third telescopic cylinder 303, the drive motor 305, the forward and reverse motor 4, the vacuum pump 402, the lateral telescopic cylinder 501, the actuator motor 506, the drive telescopic cylinder 604, and the synchronous motor 701.

[0063] The models of the above electrical components are as follows: drive motor 305 is a three-phase asynchronous motor of model "Y2-90L-4"; synchronous motor 701 is a stepper motor of model "60YS060J3", which is synchronously driven by a PLC controller; actuator motor 506 is a miniature geared motor of model "GM12-300"; forward and reverse motor 4 is a three-phase asynchronous motor of model "Y132S-4"; first telescopic cylinder 201, second telescopic cylinder 207 and third telescopic cylinder 303 are all hydraulic telescopic cylinders of model "HOB63×100"; lateral telescopic cylinder 501 is a cylinder of model "SC80×300"; drive telescopic cylinder 604 is model "HGL63×500".

[0064] Example 4:

[0065] The forming method of the above-mentioned heat-insulating and heating riser forming equipment includes the following forming steps:

[0066] S1. Expanded perlite, quartz sand, aluminum powder, magnesium powder, iron oxide powder, potassium nitrate, sodium chloride, alkaline phenolic resin, organic ester and coupling agent are poured into the raw slurry mixing tank 1 in proportion, and the raw materials are fully mixed by stirring fan blade 101.

[0067] S2. During pouring, the upper mold 211 and the lower mold 209 are tightly fitted together. The upper mold 211 and the lower mold 209 are lowered and submerged into the mixed slurry in the slurry mixing tank 1 by the first telescopic cylinder 201, and the raw material is poured into the mold.

[0068] S3. After vacuum pump 402 evacuates the riser in the mold after pouring, the mold rises away from the surface of the original slurry pool. Scraper 502 moves to scrape off the original slurry attached to the top of the upper mold 211. When scraper 502 moves to the position of placement block 503, horizontal scraper 508 moves to scrape off the original slurry at the front end of scraper 502.

[0069] S4. The second telescopic cylinder 207 raises the upper mold 211, the third telescopic cylinder 303 drives the lifting plate 304 to descend, the smoothing knife 311 moves down to the outside of the riser after pouring, and the drive motor 305 drives the smoothing knife 311 to rotate, and performs preliminary smoothing on the outside of the riser.

[0070] S4. The forward and reverse motor 4 starts and drives the lower mold 509 to flip. The placement platform 6 moves the bottom of the lower mold 509. The striking device 7 starts and the striking rod 707 strikes the lower mold 509 to assist in demolding. The riser after demolding falls on the placement platform 6. With the start of the drive telescopic cylinder 604, the placement platform 6 moves out of the top of the raw pulp mixing tank 1.
