Description

Technical Field

[0001] The invention relates to the technical field of pump body casting, and in particular to a pump body and casing combined casting mold and a use method thereof. Background Art

[0002] Cast iron has good corrosion resistance and is widely used in pump housings. It is also manufactured by casting during production, which can relatively reduce production costs. The traditional casting process is sand casting, which requires the upper and lower mold cavities to be made by compacting and filling the molding sand. The disadvantage of this casting process is that the sand mold will be destroyed every time the material is taken, resulting in low production efficiency and is not conducive to large-scale casting production.

[0003] With the development of casting technology, alloy casting molds have emerged. The mold cavity is made of alloy, so that the mold cavity will not be damaged when the material is taken out, which is conducive to large-scale casting production. However, the existing casting molds usually dissipate heat naturally while waiting for the molten metal to cool, and the cooling and molding process takes a long time, which prolongs the production cycle and reduces production efficiency.

[0004] In the prior art, cooling is usually performed by injecting coolant into the upper die base and the lower die base. However, when the upper die base is separated from the lower die base, the coolant inside the upper die base cannot be completely discharged. Since this part of the coolant has absorbed heat, the cooling rate of the upper die base is slowed down, thereby affecting subsequent normal casting. Summary of the invention

[0033] (2) After the casting is completed, the pump body can directly extract the cooling liquid after absorbing heat in the lower heat dissipation cavity through the heat dissipation pipe, and correspondingly, the cooling liquid in the upper heat dissipation cavity can be discharged synchronously through the liquid discharge mechanism, so as to avoid the phenomenon that the cooling liquid after absorbing heat cannot be discharged and the upper die seat dissipates heat slowly, thereby further improving the casting efficiency of the pump body casing;

[0034] (3) When the mold base of the present invention is engaged with the mold cavity, each drain pipe can be synchronously plugged into the liquid outlet. As the coolant is continuously transported to the heat dissipation cavity, the coolant can be transported to the coolant tank again through the liquid inlet, the reflux pipe, the liquid outlet, the drain pipe, the circulation pipe and the liquid outlet pipe, thereby achieving the effect of circulating the coolant. The coolant transported to the coolant tank can be cooled again to improve the subsequent cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1 As shown, the present invention is a pump body casing combined casting mold, including a base 1, on which a lower mold base 2 is fixedly arranged; specifically, the lower mold base 2 can be fixed to the base 1 by a plurality of groups of pillars, and the pillars are fixed to the base 1 and the lower mold base 2 by welding or bolting.

[0045] In this embodiment, an upper mold base 201 is arranged on the lower mold base 2, and the upper mold base 201 is connected to the lifting module 101 that drives it to rise and fall, wherein a mold cavity 202 is opened on the lower mold base 2, and a mold base 203 corresponding to the mold cavity 202 is fixedly arranged on one side of the upper mold base 201 facing the lower mold base 2; it should be noted that, please refer to Figure 1 and Figure 5 The lifting module 101 can drive the upper mold base 201 to move toward the lower mold base 2. When the mold base 203 is completely embedded in the mold cavity 202, the lower surface of the upper mold base 201 and the upper surface of the lower mold base 2 are also completely fitted. At this time, the side wall of the mold base 203 and the mold cavity 202 are enclosed to form a casting cavity for casting the pump body casing;

[0046] It should be noted that in order to form a casting cavity, the volume of the mold base 203 needs to be smaller than the volume of the mold cavity 202. This embodiment does not limit the specific shape and size of the casting cavity, which can be set accordingly based on the pump body casing.

[0047] See also Figure 2 as well as Figure 4 A lower heat dissipation cavity 501 is provided on one side of the lower die base 2 close to the mold cavity 202, one side of the lower heat dissipation cavity 501 is respectively communicated with a plurality of groups of lower heat dissipation channels 502 provided in the lower die base 2, the ends of the lower heat dissipation channels 502 are communicated with a receiving tube 503 fixedly arranged on the lower die base 2, a heat dissipation pipe 5 communicating with the lower heat dissipation cavity 501 is fixedly arranged on the bottom of the lower die base 2, and the heat dissipation pipe 5 is connected to the coolant tank through a pump body; in this embodiment, during the casting process, the pump body extracts the coolant in the coolant tank, and then transports it to the lower heat dissipation cavity 501 through the heat dissipation pipe 5, and since the lower heat dissipation cavity 501 is adjacent to the mold cavity 202, the workpiece after casting in the mold cavity 202 can be cooled;

[0048] Furthermore, an upper heat dissipation cavity 602 is provided in the mold base 203, and a plurality of upper heat dissipation channels 601 are provided on one side of the upper mold base 201. One end of the upper heat dissipation channel 601 is connected with the upper heat dissipation cavity 602 through a heat dissipation outlet 603, and the other end is provided with an upper heat dissipation outlet 6 for correspondingly plugging into the receiving tube 503. In the present embodiment, when the mold base 203 is engaged with the mold cavity 202, the receiving tube 503 is correspondingly plugged into the upper heat dissipation outlet 6. During the casting process, as the pump body continues to input coolant into the lower heat dissipation cavity 501, the coolant can be transported to the upper heat dissipation cavity 602 through the lower heat dissipation channel 502, the receiving tube 503, the upper heat dissipation outlet 6, the upper heat dissipation channel 601 and the heat dissipation outlet 603, thereby achieving heat dissipation and cooling of the mold base 203 and the workpiece after casting.

[0049] It should be noted that in this embodiment, the lower heat dissipation channel 502 is an L-shaped structure, and the upper heat dissipation channel 601 is an inverted U-shaped structure. Therefore, after casting is completed, the coolant in the upper heat dissipation cavity 602 that absorbs heat cannot be completely discharged.

[0050] It also includes a drainage mechanism arranged in the upper heat dissipation cavity 602, which is used to discharge the coolant in the cavity; it can be explained that after the casting is completed, the pump body can directly extract the coolant after absorbing heat in the lower heat dissipation cavity 501 through the heat dissipation pipe 5, and correspondingly, the coolant in the upper heat dissipation cavity 602 can be discharged synchronously through the drainage mechanism to avoid the coolant after absorbing heat cannot be discharged and cause the upper mold base 201 to dissipate heat slowly, thereby further improving the casting efficiency of the pump body casing.

[0051] Example 2

[0052] Based on Example 1, please refer to Figure 2 and Figure 4The upper mold base 201 also has several groups of return pipes 611, which are symmetrically arranged with the upper heat dissipation channel 601. One end of the return pipe 611 is provided with a liquid inlet 613 connected with the upper heat dissipation cavity 602, and the other end is provided with a liquid outlet 612. The lower mold base 2 also has several groups of circulation pipes 505, which are symmetrically arranged with the lower heat dissipation channel 502. The lower mold base 2 is correspondingly fixed with several groups of drainage pipes 504 connected with the circulation pipes 505. The other end of the circulation pipe 505 is connected with the liquid outlet pipe 402. Tube 402 is connected to the coolant tank; it can be explained that when the mold base 203 is engaged with the mold cavity 202, each drain pipe 504 can be synchronously plugged into the liquid outlet 612. As the coolant is continuously transported to the upper heat dissipation cavity 602, the coolant can be transported to the coolant tank again through the liquid inlet 613, the reflux pipe 611, the liquid outlet 612, the drain pipe 504, the circulation pipe 505 and the liquid outlet pipe 402, thereby achieving the effect of circulating the coolant. The coolant transported to the coolant tank can be cooled again to improve the subsequent cooling effect.

[0053] In this embodiment, a semicircular feed barrel 204 connected to the mold cavity 202 is fixedly arranged on one side of the lower mold base 2, and an upper material barrel 205 is fixedly arranged on one side of the upper mold base 201, and a feed port 207 is connected to the upper material barrel 205, wherein a notch 206 for engaging with the semicircular feed barrel 204 is correspondingly opened on one side of the bottom of the upper material barrel 205; it can be explained that during casting, as the upper mold base 201 and the lower mold base 2 are fitted together, the semicircular feed barrel 204 can be embedded in the notch 206 of the upper material barrel 205, and the molten metal casting liquid is discharged into the upper material barrel 205 through the feed port 207, and finally can be discharged into the casting cavity for casting.

[0054] As a further solution of this embodiment, please refer to Figure 2-Figure 4 The discharge mechanism includes a heat conducting plate 604 embedded in the upper heat dissipation cavity 602, the outer edge of the heat conducting plate 604 is slidably fitted with the inner wall of the upper heat dissipation cavity 602, a lifting rod 605 is fixedly arranged on the heat conducting plate 604, a lifting channel 608 is provided on the upper mold base 201, and the lifting rod 605 passes through the lifting channel 608 and is connected to the lifting module 101, wherein the diameter of the lifting rod 605 is smaller than the inner diameter of the lifting channel 608; it can be explained that when the lifting module 101 drives the upper mold base 201 to fit with the lower mold base 2, the heat conducting plate 604 is slidably fitted with the inner wall of the upper heat dissipation cavity 602, a lifting rod 605 is fixedly arranged on the heat conducting plate 604, and a lifting channel 608 is provided on the upper mold base 201, and the lifting rod 605 passes through the lifting channel 608 and is connected to the lifting module 101, wherein the diameter of the lifting rod 605 is smaller than the inner diameter of the lifting channel 608; it can be explained that when the lifting module 101 drives the upper mold base 201 to fit with the lower mold base 2, the lifting rod 605 is The heat plate 604 is at the bottom of the upper heat dissipation cavity 602 at this time. When the casting is completed, the lifting module 101 can first drive the heat conductive plate 604 to rise in the upper heat dissipation cavity 602 through the lifting rod 605, and the heat conductive plate 604 can squeeze the coolant in the upper heat dissipation cavity 602 upward and discharge it through the gap between the lifting rod 605 and the lifting channel 608, thereby achieving the drainage effect, until the heat conductive plate 604 moves to the top position of the upper heat dissipation cavity 602, so as to squeeze and discharge all the coolant in the upper heat dissipation cavity 602.

[0055] Furthermore, in order to completely discharge the coolant in the upper heat dissipation channel 601 and the return pipe 611, in the present embodiment, a plurality of push rods 607 corresponding to the upper heat dissipation channel 601 and the return pipe 611 are fixedly arranged on the heat conducting plate 604, and a plunger 606 is fixedly arranged on the push rod 607, and the plunger 606 is made of silicone material; it can be explained that as the heat conducting plate 604 rises in the upper heat dissipation cavity 602, the heat conducting plate 604 can push the plunger 606 to rise through the push rod 607, and the plunger 606 can move upward along the upper heat dissipation channel 601 and the return pipe 611, thereby pushing out the coolant in the upper heat dissipation channel 601 and the return pipe 611 and discharging it from the upper heat dissipation port 6 and the liquid outlet 612 respectively.

[0056] In order to collect the coolant discharged from the lifting channel 608, in this embodiment, a sealing cover 4 is fixedly arranged at the top of the lifting channel 608, the lifting rod 605 is slidably connected to the sealing cover 4, and one side of the sealing cover 4 is connected to the coolant tank through the telescopic tube 401; it can be explained that the coolant is first squeezed and discharged into the sealing cover 4 from the lifting channel 608, and finally can flow back to the coolant tank through the telescopic tube 401 for recycling.

[0057] It should be noted that this embodiment does not require the use of a pump to circulate the coolant, which reduces costs and increases stability.

[0058] See also Figure 3 In addition, when in the normal casting state, in order to prevent the coolant from being discharged from the lifting channel 608, in this embodiment, a first annular flange 609 is fixedly arranged at one end of the lifting channel 608 close to the upward heat dissipation cavity 602, and a second annular flange 610 is correspondingly fixedly arranged on the lifting rod 605, wherein the inner diameter of the first annular flange 609 is larger than the diameter of the lifting rod 605 and smaller than the outer diameter of the second annular flange 610, and the outer diameter of the second annular flange 610 is smaller than the inner diameter of the lifting channel 608; it can be explained that in the normal casting state, the second annular flange 610 contacts the first annular flange 609, thereby achieving the effect of sealing the lifting channel 608, and the coolant in the upper heat dissipation cavity 602 cannot be discharged from the lifting channel 608. As the lifting rod 605 drives the heat conducting plate 604 to rise, the second annular flange 610 separates from the first annular flange 609, and the coolant in the upper heat dissipation cavity 602 can be discharged into the lifting channel 608 through the gap between the two.

[0059] See also Figure 1-Figure 2In this embodiment, the lifting module 101 is fixedly arranged on one side of the base 1, and the lifting end of the lifting module 101 is connected to the lifting plate 302 through the support shaft 303, wherein the lifting rod 605 is fixedly arranged at the end of the lifting plate 302; specifically, the lifting module 101 of this embodiment can adopt a screw nut transmission mechanism or a synchronous belt transmission mechanism. It can be explained that when driving the heat conduction plate 604 to rise and fall, the lifting module 101 can first drive the lifting plate 302 to rise and fall through the support shaft 303, and the lifting plate 302 can drive the heat conduction plate 604 to rise and fall through the lifting rod 605.

[0060] Furthermore, in order to discharge all the coolant remaining in the lifting channel 608 and the sealing cover 4, in the present embodiment, one end of the support shaft 303 is rotatably connected to the lifting end of the lifting module 101, and the other end thereof is fixed to the lifting plate 302. A gear 3 is fixedly arranged on the support shaft 303, and a rack 301 for engaging with the gear 3 is fixedly arranged on the lifting module 101. It can be explained that when the lifting module 101 drives the lifting plate 302 to rise to a preset height, the gear 3 can drive the upper mold base 201 to rotate 180 degrees by engaging with the rack 301, so that the remaining coolant can be completely discharged through the telescopic tube 401, and when the lifting module 101 drives it to reset, the angle of the upper mold base 201 can be reset synchronously.

[0061] It should be noted that in order to improve the stability of the upper mold base 201 during lifting and lowering, a guide groove and a guide seat can be provided on one side of the lifting module 101 to guide the movement of the upper mold base 201 to avoid deflection during lifting and lowering.

[0062] A method for using a pump body and casing combined casting mold comprises the following steps:

[0063] See also Figure 1-Figure 2 as well as Figure 4-Figure 5 The lifting module 101 drives the upper mold base 201 to move toward the lower mold base 2, so that the mold base 203 is embedded in the mold cavity 202, and the side wall of the mold base 203 and the mold cavity 202 are enclosed to form a casting cavity for casting the pump body casing;

[0064] The molten metal casting liquid is discharged into the casting cavity through the feed port 207 and the upper barrel 205 for casting;

[0065] During the casting process, the pump body extracts the coolant in the coolant tank and transports it to the lower heat dissipation cavity 501 through the heat dissipation pipe 5 to cool the workpiece after casting in the mold cavity 202;

[0066] As the pump body continues to input the coolant into the lower heat dissipation cavity 501, the coolant can be transported to the upper heat dissipation cavity 602 through the lower heat dissipation channel 502, the receiving tube 503, the upper heat dissipation port 6, the upper heat dissipation channel 601 and the heat dissipation port 603 for further cooling;

[0067] After the casting is completed, the pump body can directly extract the coolant that has absorbed heat in the lower heat dissipation cavity 501 through the heat dissipation pipe 5, and the lifting module 101 drives the heat conduction plate 604 to rise in the upper heat dissipation cavity 602 through the lifting rod 605. The heat conduction plate 604 squeezes the coolant in the upper heat dissipation cavity 602 upward and discharges it through the gap between the lifting rod 605 and the lifting channel 608 until the heat conduction plate 604 moves to the top position of the upper heat dissipation cavity 602;

[0068] As the lifting module 101 drives it to continue to rise, the upper die base 201 can be driven to separate from the lower die base 2 through the heat conducting plate 604, and the pump body casing workpiece after casting can be taken out.
