[0001] This application relates to the technical field of finishing of lost foam molds, and specifically provides a workbench for finishing lost foam molds. Background Art

[0002] When producing lost foam, lost foam molds are required. After the lost foam molds are produced, due to their relatively high surface roughness, they need to be subjected to finishing treatment, such as deburring and smoothness grinding. Due to the high surface complexity of the lost foam molds, the surface finishing of the molds is usually manually operated by workers. Specifically, during the operation, the mold needs to be first hoisted onto the workbench, and the worker holds a grinding device to process the surface of the mold.

[0026] Please refer to Figures 1-5 , the present application provides the following technical solution: A workbench for finishing a lost foam mold, including a base 11 and a pallet 4; in the middle of the upper surface of the base 11, there is a sleeve 9, the inner side surface of the sleeve 9 is rotatably connected with a turntable 8, the upper surface of the turntable 8 is equipped with an adjustable telescopic rod 10, and a turntable positioning device is installed on the upper surface of the base 11.

[0027] Specifically, fix the lost foam mold to be processed on the upper surface of the pallet 4. By rotating the turntable 8, the rotation adjustment of the mold can be achieved. After the adjustment is completed, the position of the turntable 8 can be locked by the turntable positioning device.

[0028] The upper end surface of the adjustable telescopic rod 10 is equipped with a support seat 15. In the middle of the lower surface of the pallet 4, there is a positioning wheel 13 fixedly connected. On the central axis of the positioning wheel 13, there is a support shaft 14. The outer side end of the support shaft 14 is rotatably connected with the support seat 15 through a positioning bearing 18. An angle locator is installed on the support seat 15, and a pitch adjuster for controlling the rotation of the pallet 4 is installed on the upper surface of the support seat 15.

[0029] Specifically, the pitch adjuster can push to control the pitch adjustment of the pallet 4. When the pallet 4 rotates, the support seat 15 can support and fix it.

[0030] On the upper surface of the pallet 4, there are a transverse chute 2 and a vertical chute 1. At the bottom of the inner side surfaces of the transverse chute 2 and the vertical chute 1, there are bar-shaped array tooth grooves 5 laid. The inner side surfaces of the transverse chute 2 and the vertical chute 1 are each slidably connected with not less than one slider 6. On the upper surface of the slider 6, there is an inverted trapezoidal clamp 3. Near the edge of the pallet 4 on the outer side surface of the slider 6, there is a through hole 29. The inner side surface of the through hole 29 is slidably connected with a second inserting rod 27. The lower end of the outer side surface of the second inserting rod 27 is arranged corresponding to be clamped with the groove of the bar-shaped array tooth groove 5. Between the outer side surface of the second inserting rod 27 and the inner side surface of the through hole 29, there is a second return spring 28.

[0031] Specifically, slide and adjust the slider 6 so that the trapezoidal clamping block 3 provided on the upper surface of the slider 6 can be clamped on the outer surface of the mold to be processed, thereby realizing the fixation of the mold. When the slider 6 moves, the second inserting rod 27 needs to be pulled out first. After the slider 6 moves to a suitable position, release the second inserting rod 27, and the second inserting rod 27 is inserted into the groove of the strip-shaped array tooth groove 5 under the action of the second spring 28, thereby realizing the position fixation of the slider 6.

[0032] Further, mounting holes 12 are provided at the edge of the upper surface of the base 11.

[0033] Specifically, the base 11 can be fixed to the ground through the mounting holes 12, thereby increasing the stability of the equipment.

[0034] Further, the turntable positioning device includes a cylindrical barrel 22 installed on the upper surface of the base 11. An annular array of slots 19 is provided on the outer side surface of the turntable 8. A first inserting rod 7 is slidably connected to the inner side surface of the cylindrical barrel 22.

A baffle 20 is provided on the outer side surface of the first inserting rod 7, and the baffle 20 is connected to the inner side surface of the cylindrical barrel 22 through a first return spring 21.

[0035] Specifically, when rotating the turntable 8, the first inserting rod 7 needs to be pulled out first. After the turntable 8 rotates to a suitable position, release the first inserting rod 7, and the first inserting rod 7 is inserted into the groove of the annular array of slots 19 under the push of the first return spring 21, thereby realizing the position fixation of the turntable 8.

[0036] Further, the angle locator includes an electric control telescopic rod 16 installed on the support base 15. An inserting tooth is installed at the telescopic end of the electric control telescopic rod 16. An arc-shaped array of slots 17 is provided on the outer side surface of the positioning wheel 13, and the inserting tooth is correspondingly clamped with the arc-shaped array of slots 17.

[0037] Specifically, when the support plate 4 is adjusted in pitch, the support plate 4 drives the positioning wheel 13 to rotate. After the pitch angle of the support plate 4 is adjusted, the electric control telescopic rod 16 extends to insert the inserting tooth into the groove of the arc-shaped array of slots 17, thereby preventing the positioning wheel 13 from rotating.

[0038] Further, the pitch adjuster includes two pneumatic telescopic rods 24. A universal ball support 23 is installed at the telescopic end of the pneumatic telescopic rod 24. The two pneumatic telescopic rods 24 are respectively installed at the front and rear ends of the upper surface of the support base 15.

[0039] Specifically, one of the two pneumatic telescopic rods 24 contracts and the other synchronously extends, thereby pushing the support plate 4 to complete the pitch adjustment.

[0040] Further, the horizontal chute 2 and the vertical chute 1 are vertically and crosswise arranged, and the number of both the horizontal chute 2 and the vertical chute 1 is not less than one.

[0041] Specifically, the provision of multiple horizontal sliding grooves 2 and vertical sliding grooves 1 can achieve firm fixation of the mold.

The outer side surface of the trapezoidal clamping block 3 is threadedly connected with an adjusting screw rod 26, and the end of the adjusting screw rod 26 is rotatably connected to the pressing block 25.

[0043] Specifically, by rotating the adjusting screw rod 26, the pressing block 25 can be pushed to move, so that the pressing block 25 can tightly press against the outer surface of the mold, and displacement of the mold during the finish machining process can be avoided.

[0044] During use: Place the lost foam mold to be processed on the upper surface of the support plate 4, slide and adjust the slider 6 so that the trapezoidal clamping block 3 provided on the upper surface of the slider 6 can be clamped on the outer surface of the mold to be processed, thereby realizing fixation of the mold. When the slider 6 moves, the second insertion rod 27 needs to be pulled out first. After the slider 6 moves to a suitable position, release the second insertion rod 27, and the second insertion rod 27 is inserted into the groove of the strip-shaped array tooth groove 5 under the action of the second spring 28. Then, by rotating the adjusting screw rod 26, the pressing block 25 can be pushed to move, so that the pressing block 25 can tightly press against the outer surface of the mold, and displacement of the mold during the finish machining process can be avoided.

[0045] When the mold is adjusted in pitch, one of the two pneumatic telescopic rods 24 contracts and the other synchronously extends, thereby pushing the support plate 4 to complete the pitch adjustment. When the support plate 4 is adjusted in pitch, the support plate 4 drives the positioning wheel 13 to rotate. After the pitch angle of the support plate 4 is adjusted, the electric control telescopic rod 16 extends and inserts the insert tooth into the groove of the arc-shaped array slot 17, thereby preventing the positioning wheel 13 from rotating.

[0046] When the mold is adjusted in rotation, by rotating the turntable 8, the rotation adjustment of the mold can be achieved. When rotating the turntable 8, the first insertion rod 7 needs to be pulled out first. After the turntable 8 rotates to a suitable position, release the first insertion rod 7, and the first insertion rod 7 is inserted into the groove of the annular array slot 19 under the push of the first return spring 21, thereby realizing the position fixation of the turntable 8.

[0047] It should be noted that the input ends of the electric control telescopic rod 16 and the pneumatic telescopic rod 24 in this application are both electrically connected to the output end of the external power supply through an external controller.

[0048] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
