[0003] When processing floor drains, a casting press is required to fill the mold with the casting slurry under a specified pressure and solidify under continuous pressure. After cooling and demolding, the casting is obtained.
[0004] At present, there are many shapes of floor drains, so many different shapes of molds are often configured. When preparing different floor drains, different molds need to be replaced. In the prior art, bolts are often used to fix the mold to the workbench, and the installation and removal of the bolts are manual operations, which is very troublesome and inefficient.

[0010] Preferably, a cylindrical platform is provided in the middle of one end of the limiting block close to the limiting groove, and the diameter of the cylindrical platform is the same as the diameter of the end faces of the two limiting grooves close to one end.
[0011] Preferably, the axial length of the limiting groove is greater than the axial length of the limiting block.
[0012] Preferably, the mold is provided with first scale lines on both sides close to the limit blocks, and the first scale lines are vertical lines; the top surface of the workbench is provided with second scale lines, and the second scale lines are horizontal lines; the second scale lines and the first scale lines are both located in the vertical plane where the center line connecting the two limit blocks is located.
[0013] Preferably, the top surface of the workbench is provided with a third scale line perpendicular to the second scale line, and the third scale line is a horizontal line; the outer walls on both sides of the mold are symmetrically provided with fourth scale lines, and the fourth scale line is a vertical line; the third scale line is coplanar with the fourth scale line and the coplanarity is perpendicular to the length direction of the screw rod, and the midpoint of the line connecting the centers of the two limit blocks is located on the coplanarity.

[0015] By setting limit blocks on both sides of the mold and a driving device that drives the two limit blocks to move toward or away from each other in the horizontal direction, the two limit blocks can be moved toward or away from each other at the same speed. By setting limit grooves that match the limit blocks on both sides of the mold, the two limit blocks can be inserted into the limit grooves at the same time when the two limit blocks move toward each other at the same speed. By applying an extrusion force to the mold in the horizontal direction by the two limit blocks, the mold can be prevented from being displaced in the direction in which the two limit blocks move. By making the limit blocks slidably connected to the inner wall of the limit groove, the mold can be prevented from moving in a direction perpendicular to the moving direction of the two limit blocks, thereby achieving the purpose of limiting the mold to the workbench. Compared with the prior art that directly limits the mold to the workbench by bolts manually, the utility model does not require manual operation and is simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1
[0022] A die casting device, such as Figure 1-3 As shown, it includes a workbench 100 and a mold 110 detachably arranged on the workbench 100. There are multiple molds 110, and a mold 110 that matches the shape of the floor drain to be processed is selected each time during die-casting. Since the shapes of different molds 110 are different, the shape of the mold 110 is not limited here, and it can be any mold 110 that can die-cast a floor drain.
[0023] In addition, if Figure 3 As shown, the die-casting device also includes a limit block 120 arranged on the top surface of the workbench 100 and located on both sides of the mold 110, and a driving device for driving the two limit blocks 120 to move toward or away from each other in the horizontal direction; limit grooves 130 adapted to the limit blocks 120 are respectively arranged on both sides of the mold 110, and the limit blocks 120 and the limit grooves 130 are slidably connected.
[0024] Working principle: first place the mold 110 on the workbench 100 and in the middle of the two limit blocks 120, then start the driving device to make the two limit blocks 120 move toward each other synchronously, during the displacement process, the two limit blocks 120 gradually approach the limit groove 130 and fully extend into the limit groove 130, during the continuous displacement process, the limit blocks 120 are slidably connected with the limit groove 130 until the two limit blocks 120 and the two limit grooves 130 are completely abutted against each other on one side, and then the displacement is stopped. At this time, the two limit blocks 120 respectively apply opposite horizontal forces to the mold 110, which can prevent the mold 110 from moving in the left and right directions; at the same time, because the limit blocks 120 are slidably connected with the limit grooves 130, it is possible to prevent the mold 110 from moving in the front and back directions, thereby achieving the purpose of limiting the mold 110 to the workbench 100.
[0025] Further, such as Figure 1-3As shown, the driving device includes a connecting plate 140 arranged on the top surface of the workbench 100 and located on both sides of the mold 110, a screw rod 150 and a sliding rod 160 arranged side by side between the two connecting plates 140, two moving blocks 170 simultaneously sleeved on the screw rod 150 and the sliding rod 160, and a motor 180 arranged on one of the connecting plates 140 and fixedly connected to one end of the screw rod 150; the two limit blocks 120 are respectively arranged on the side where the two moving blocks 170 are close to each other; the screw rod 150 and the moving block 170 are threadedly connected, and the sliding rod 160 and the moving block 170 are slidably connected; the screw rod 150 and the sliding rod 160 are respectively located on both sides of the mold 110; the screw rod 150 is bounded by the vertical plane where the midpoint of the line connecting the two limit blocks 120 is located, and the screw rod 150 is set to have two left and right sections of threads with different directions. In specific implementation, the motor 180 is driven, and under the action of the motor 180, the screw rod 150 is rotated, so that the two moving blocks 170 are synchronously displaced toward or away from each other on the screw rod 150, and the two limit blocks 120 are driven to displace synchronously.
[0026] Further, such as Figure 1-4 As shown, the limit block 120 and the limit groove 130 are both truncated cone-shaped. Furthermore, a cylindrical cone is provided in the middle of one end of the limit block 120 close to the limit groove 130, and the diameter of the cylindrical cone is the same as the diameter of the end surface of the two limit grooves 130 close to each other. The truncated cone shape can maximize the contact area between the limit block 120 and the limit groove 130, thereby improving the tightness of the connection between the limit block 120 and the limit groove 130. In addition, by providing the cylindrical cone, not only can it be in close contact with the two limit grooves 130 close to each other at one end, but it can also be just clamped at the end of the limit groove 130 to prevent the mold 110 from slightly displacing in the front-to-back direction.
[0027] Further, such as Figure 2-4As shown, the mold 110 is provided with first scale lines 190 on both sides close to the limit block 120, and the first scale lines 190 are vertical lines; the top surface of the workbench 100 is provided with second scale lines 200, and the second scale lines 200 are horizontal lines; the second scale lines 200 and the first scale lines 190 are both located on the vertical plane where the center line of the two limit blocks 120 is located. Further, the top surface of the workbench 100 is provided with third scale lines 210 perpendicular to the second scale lines 200, and the third scale lines 210 are horizontal lines; the outer walls on both sides of the mold 110 are symmetrically provided with fourth scale lines 220, and the fourth scale lines 220 are vertical lines; the third scale lines 210 and the fourth scale lines 220 are coplanar, and the coplanarity is perpendicular to the length direction of the screw rod 150, and the midpoint of the center line of the two limit blocks 120 is located on the coplanarity.
[0028] During specific implementation, the second scale line 200 on the mold 110 is aligned with the first scale line 190 ; the third scale line 210 is aligned with the fourth scale line 220 , so as to ensure that the mold 110 is placed exactly in the middle of the two limit blocks 120 .
[0029] It is worth noting that the present invention only improves the limiting device of the die 110, and does not describe other devices of the die-casting device, such as the upper die, the press that drives the upper die to move vertically, and the connection relationship between these devices, which are all prior art and will not be described in detail here. After the die 110 is limited to the workbench 100, the die-casting operation can be performed using the prior art.
[0030] In the description of this patent, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal" and the like indicate the orientation or position relationship based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing this patent and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this patent.
