Description

Technical Field

[0001] This utility model relates to the field of blowers, and in particular to a weight configuration adjustment mold for an automotive air conditioning blower. Background Technology

[0002] Existing automotive air conditioning blowers include a motor, impeller, and volute, with the impeller being a reference component. Figure 1 After the impeller is formed, the center of gravity of the impeller needs to be detected by a dynamic balancing machine. After the impeller is detected, counterweights need to be installed in the lighter parts of the impeller. However, it is time-consuming to install counterweights manually after the impeller is formed, resulting in low impeller production efficiency. Utility Model Content

[0003] This invention addresses the drawback of existing technologies where manual installation of counterweights is required after impeller molding, resulting in low impeller production efficiency. It provides a weight configuration adjustment mold for automotive air conditioning blowers that can improve impeller production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A weight configuration adjustment mold for an automotive air conditioning blower includes an upper mold and a lower mold. After the two molds are closed, a forming cavity is formed inside for forming an impeller. The upper mold is provided with a counterweight forming component that forms a counterweight on the impeller when the impeller is formed. The counterweight forming component includes a forming groove recessed at one end of the upper mold near the lower mold. The upper mold is provided with a depth adjusting component for adjusting the groove depth.

[0005] Using the above scheme, the forming groove set near the lower mold of the upper mold can form a counterweight on the formed impeller after the upper and lower molds are closed, making the center of gravity of the formed impeller more balanced. At the same time, since the counterweight is formed together with the impeller during the forming process, there is no need for workers to install it after forming, thereby reducing the steps in impeller production and improving production efficiency. The depth adjustment component set on the upper mold can adjust the depth of the forming groove, thereby adjusting the mass of the counterweight after forming, so that the center of gravity of the formed impeller is adjusted.

[0006] Preferably, the depth adjustment component includes an adjustment groove vertically arranged in the upper mold and a lifting rod vertically arranged in the adjustment groove. The forming groove is located at one end of the adjustment groove near the lower mold, and the bottom of the forming groove is at the end of the lifting rod near the lower mold. The upper mold is provided with a lifting component for driving the lifting rod to rise and fall.

[0007] Using the above scheme, the lifting rod set in the adjustment groove and the inner wall of the adjustment groove near the lower mold are combined to form a molding groove. The lifting component can adjust the position of the lifting rod in the adjustment groove, thereby adjusting the depth of the molding groove and allowing counterweights of different masses to be formed at the molding groove.

[0008] Preferably, the lifting component includes a threaded hole vertically disposed in the upper mold and communicating with the adjustment groove, an extrusion bolt disposed in the threaded hole with one end passing through the threaded hole and inserted into the adjustment groove, which compresses the lifting rod to move vertically downward when screwed into the threaded hole, and a pulling component disposed between the bottom of the adjustment groove and the end of the lifting rod near the bottom of the adjustment groove, which pulls the lifting rod toward the bottom of the adjustment groove when the extrusion bolt rotates outward from the threaded hole.

[0009] Using the above scheme, the extrusion bolt installed in the threaded hole can push the lifting rod to move closer to the lower mold when it is screwed into the threaded hole, thereby reducing the depth of the forming groove and reducing the mass of the counterweight after forming. When the extrusion nut rotates outward from the threaded hole, the pulling component set between the adjusting groove and the lifting rod will pull the adjusting rod towards the bottom of the adjusting groove, thereby moving the lifting rod away from the lower mold. At this time, the depth of the forming groove will increase, and the mass of the counterweight after forming will increase.

[0010] Preferably, the pulling component includes a tension spring with both ends connected to the bottom of the adjusting groove and the end of the lifting rod near the bottom of the adjusting groove.

[0011] Using the above scheme, a tension spring is installed at the bottom of the adjusting groove and at the end of the lifting rod near the bottom of the adjusting groove. When the extrusion bolt rotates outward from the threaded hole, it pulls the lifting rod towards the bottom of the adjusting groove, thereby increasing the depth of the forming groove. At this time, the mass of the counterweight block after forming will increase accordingly.

[0012] Preferably, the top of the compression bolt is provided with an operating component that facilitates the operator to rotate the compression bolt.

[0013] Preferably, the operating component includes a slot horizontally inserted at the top of the compression bolt and a force-adding plate inserted in the slot to facilitate the operator's rotation of the compression bolt. The force-adding plate is provided with a blocking component to prevent the end of the force-adding plate away from the insertion end from passing through the slot after it is inserted.

[0014] Using the above scheme, the force-adding plate can be inserted into the slot at the top of the clamping bolt when the operator needs to rotate the clamping bolt. When the force-adding plate is inserted into the slot, the operator can rotate the clamping bolt by rotating the force-adding plate, thereby adjusting the position of the lifting rod in the adjustment slot. The blocking component on the force-adding plate can prevent the end of the force-adding plate away from its insertion end from going out of the slot after it is inserted, thus making it more convenient for the operator to use the force-adding plate.

[0015] Preferably, the blocking component includes a blocking plate disposed on the force-adding plate, the surface of which abuts against the top surface of the extrusion bolt when the force-adding plate is inserted into the through groove.

[0016] Using the above scheme, the baffle plate set on the force-adding plate can be inserted into the through groove at one end of the force-adding plate and abut against the surface of the top surface of the extrusion bolt, thereby limiting the depth of the force-adding plate inserted into the through groove and preventing the force-adding plate from being over-inserted into the through groove.

[0017] Preferably, the upper die is provided with a storage component for storing the extrusion bolt when the force plate is removed from the extrusion bolt.

[0018] Preferably, the storage component includes a storage groove with the same shape as the force-adding plate on the upper mold, and a limiting plate is provided on the inner wall of the storage groove away from the bottom of the groove to prevent the force-adding plate from coming out of the storage groove when it is stored in the storage groove. The upper mold is provided with an operation groove that is connected to one end of the storage groove and facilitates the operator to take the force-adding plate out of the storage groove.

[0019] Using the above solution, the storage slot on the upper mold can store the force plate after use and when it is removed from the slot. The limiting plate on the side wall of the storage slot, away from the bottom of the storage slot, can limit the position of the force plate when it is stored in the storage slot, reducing the probability of the force plate coming out of the storage slot. The operating slot on the upper mold makes it easy for the operator to take out the force plate stored in the storage slot.

[0020] This utility model, by adopting the above technical solutions, has significant technical effects: the forming groove set near the lower mold of the upper mold can form a counterweight on the impeller at the forming point after the upper and lower molds are closed, making the center of gravity of the formed impeller more balanced. At the same time, since the counterweight is formed together with the impeller during the forming process, there is no need for workers to install it after forming, thereby reducing the steps in impeller production and improving production efficiency. The depth adjustment component set on the upper mold can adjust the depth of the forming groove, thereby adjusting the mass of the counterweight after forming, so that the center of gravity of the formed impeller is adjusted.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] Example A weight configuration adjustment mold for an automotive air conditioning blower, reference Figures 2-3 , Figure 7 , Figure 12 The upper mold 1 and the lower mold 2 are closed together to form a forming cavity for forming the impeller 3. The upper mold 1 is provided with a counterweight forming component that forms a counterweight 4 on the impeller 3 when it is formed. The counterweight forming component includes a forming groove 5 recessed at one end of the upper mold 1 near the lower mold 2. The upper mold 1 is provided with a depth adjusting component for adjusting the groove depth of the forming groove 5. The counterweight forming component is provided with several counterweights at the center of the forming cavity.

[0025] refer to Figures 7-11The depth adjustment component includes an adjustment groove 6 vertically arranged in the upper mold 1 and a lifting rod 7 vertically arranged in the adjustment groove 6. The forming groove 5 is located at one end of the adjustment groove 6 near the lower mold 2, and the bottom of the forming groove 5 is the end of the lifting rod 7 near the lower mold 2. The upper mold 1 is provided with a lifting component for driving the lifting rod 7 to rise and fall. The lifting component includes a threaded hole 8 vertically arranged in the upper mold 1 and communicating with the adjustment groove 6, and a part of the part arranged in the threaded hole 8 that passes through the threaded hole 8 and is inserted into the adjustment groove 6. When it is screwed into the threaded hole 8, it squeezes. The lifting rod 7 has a vertically downward-moving pressing bolt 9 and a pulling component provided between the bottom of the adjusting groove 6 and the end of the lifting rod 7 near the bottom of the adjusting groove 6. When the pressing bolt 9 rotates outward toward the threaded hole 8, it pulls the lifting rod 7 toward the bottom of the adjusting groove 6. In this embodiment, the diameter of the threaded hole 8 is smaller than the size of the adjusting groove 6. The pulling component includes a tension spring 10 provided between the bottom of the adjusting groove 6 and the end of the lifting rod 7 near the bottom of the adjusting groove 6, with both ends connected to the two. In this embodiment, the adjusting groove 6 and the forming groove 5 are in the shape of round holes.

[0026] refer to Figures 4-6 The top of the compression bolt 9 is provided with an operating component that facilitates the operator to rotate the compression bolt 9. The operating component includes a through groove 12 that is horizontally inserted into the top of the compression bolt 9 and a force-adding plate 11 inserted into the through groove 12 to facilitate the operator to rotate the compression bolt 9. The force-adding plate 11 is provided with a blocking component to prevent the end of the force-adding plate 11 away from the insertion end from passing through the through groove 12 after it is inserted into the through groove 12. The blocking component includes a blocking plate 13 provided on the force-adding plate 11 whose surface abuts against the top surface of the compression bolt 9 when the force-adding plate 11 is inserted into the through groove 12.

[0027] The upper mold 1 is provided with a receiving component for receiving the extrusion bolt 9 when the force plate 11 is removed from the extrusion bolt 9. The receiving component includes a receiving groove 14 with the same shape as the force plate 11 on the upper mold 1. A limiting plate 15 is provided on the inner wall of the receiving groove 14 away from the bottom of the groove to prevent the force plate 11 from coming out of the receiving groove 14 when it is received. The upper mold 1 is provided with an operating groove 16 that is connected to one end of the receiving groove 14 and facilitates the operator to remove the force plate 11 from the receiving groove 14.

[0028] Specific forming process: When the impeller 3 needs to be formed, firstly, the upper mold 1 and the lower mold 2 are closed, and the forming cavity between the upper mold 1 and the lower mold 2 will form the impeller 3. At the same time, the forming groove 5 set on the upper mold 1 will simultaneously form the counterweight 4 on the impeller 3, so that the center of gravity of the formed impeller 3 is more balanced. When the mass of the counterweight 4 needs to be adjusted, firstly, the force plate 11 is taken out from the storage groove 14. Then, the force plate 11 is inserted into the through groove 12 on the extrusion bolt 9 of the counterweight 4 whose mass needs to be adjusted, and the blocking plate 13 on the force plate 11 is aligned with the surface of the top of the extrusion bolt 9. After contact, the force-adding plate 11 is rotated, causing the force-adding plate 11 to drive the extrusion bolt 9 to rotate. If the mass of the counterweight 4 needs to be increased, the extrusion bolt 9 is rotated outward from the threaded hole 8, and the lifting rod 7 will move towards the bottom of the adjusting groove 6 under the action of the tension spring 10. At this time, the depth of the forming groove 5 will increase, thereby increasing the mass of the formed counterweight 4. If the mass of the counterweight 4 needs to be reduced, the extrusion bolt 9 is rotated outward from the threaded hole 8, and the extrusion bolt 9 will push the lifting rod 7 towards the lower mold 2. At this time, the depth of the forming groove 5 will decrease, thereby reducing the mass of the formed counterweight 4.
