Description

Technical Field

[0001] The invention relates to the field of mold processing, and in particular to a multi-angle inclined top supporting device. Background Art

[0002] Among various types of plastic mold processing and manufacturing work, the manufacturing and processing of small inclined top parts accounts for a certain proportion. The quality of the final parts after processing will directly affect the manufacturing period and quality of the overall mold. In the traditional clamping method, its fixing method is not only single but also unsafe. During the processing, it is easy for the force applied by the processing machine to not be evenly applied to all parts of the workpiece. Due to the characteristics of the material of the workpiece itself, the clamping force of the fixture on it should not be too large, which will cause the workpiece to move relative to the fixture after the external force applied by the processing machine, and then the angle of the workpiece relative to the processing machine will change, which will have an adverse effect on the stability of the processing and the final quality after the processing is completed, highlighting its shortcomings.

DETAILED DESCRIPTION

[0013] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-Figure 3 As shown, a multi-angle inclined top support device includes a base 1, a No. 1 support frame 2, a No. 2 support frame 3, an adjusting screw 4, a handle 5, a lower transmission frame 6, a lower support rod 7, a support plate 8, an upper support rod 9, a spherical head 10, and a locking portion 11. A vertical No. 1 support frame 2 is fixed to the front of the top of the base 1, and a vertical No. 2 support frame 3 is fixed to the middle of the top. A vertical adjusting screw 4 is threadedly connected to the upper portion of the No. 1 support frame 2, a handle 5 is coaxially fixed to the upper portion of the adjusting screw 4, and a lower transmission frame 6 is hinged to the upper portion of the No. 2 support frame 3. A vertical lower support rod 7 is fixed to the rear of the top of the base 1, a horizontal support plate 8 is fixed to the top of the lower support rod 7, a vertical upper support rod 9 is slidably connected to the middle of the top of the support plate 8, a spherical head 10 is fixed to the upper portion of the upper support rod 9, and a locking portion 11 is installed on the upper support rod 9.

[0015] The locking part 11 includes a sliding seat 12, a lower transmission rod 13, an upper transmission frame 14, an upper transmission rod 15, a limiting ring 16, a support seat 17, an upper spherical groove 18, an anti-slip seat 19, a lower spherical groove 20, and a guide groove 21. The lower support rod 7 is a square column and is slidably connected with a horizontal sliding seat 12. The left and right parts of the bottom end of the sliding seat 12 are each fixed with a vertical lower transmission rod 13, and the front and rear parts are jointly hinged with a horizontal upper transmission frame 14. The left and right parts of the support plate 8 are each slidably connected with a vertical upper transmission rod 15. The upper outer walls of the two upper transmission rods 15 are respectively fixed with limiting rings 16, and the limiting rings 16 are used to limit To control the relative position of the upper transmission rod 15 and the support plate 8, thereby preventing the upper transmission rod 15 from detaching from the bottom of the support plate 8 under the action of gravity, a support seat 17 is installed above the spherical head 10, and an upper spherical groove 18 is provided in the middle of the bottom end of the support seat 17, and a vertical anti-detachment seat 19 is installed at the bottom through bolts, and a lower spherical groove 20 is provided on the upper part of the anti-detachment seat 19, and horizontal guide grooves 21 are respectively provided on the left and right parts of the bottom end of the support seat 17, and the guide grooves 21 are used to limit the relative position of the upper transmission rod 15 therewith, thereby preventing the upper transmission rod 15 from detaching from the guide grooves 21, causing the upper transmission rod 15 to be unable to support the support seat 17.

[0016] The bottom of the adjusting screw 4, the bottom of the lower transmission rod 13, and the upper and lower parts of the upper transmission rod 15 are all dome-shaped. The bottom end of the adjusting screw 4 can contact the top of the front part of the lower transmission frame 6. The upper support rod 9 can slide up and down along the support plate 8. The spherical head 10 is in surface contact with the upper spherical groove 18 and the lower spherical groove 20, and is connected to the support seat 17 through surface contact with the upper spherical groove 18 and the lower spherical groove 20. The sliding seat 12 can slide up and down along the lower support rod 7. The bottom end of the lower transmission rod 13 can contact the top of the rear part of the lower transmission frame 6. The two upper transmission rods 15 can slide up and down along the support plate 8, and the bottom ends can respectively contact the top of the upper transmission frame 14. The tops of the two upper transmission rods 15 can respectively contact the top of the inner wall of the guide groove 21.

[0017] The working principle of the present invention is as follows: when in use, the device is placed below the force application direction of the processing device, and the adjusting screw 4 is loosened so that the rear part of the lower transmission frame 6 drops to the lowest point under the action of its own gravity, so that the end of the workpiece to be processed is clamped on the fixture, and the support seat 17 is located below the other end of the workpiece to be processed. After the clamping is completed, the adjusting screw 4 is tightened. As the adjusting screw 4 is tightened, the rear part of the lower transmission frame 6 is lifted upward, thereby contacting the lower transmission rod 13 to make the sliding seat 12 and the upper transmission frame 14 move upward together. As the sliding seat 12 and the upper transmission frame 14 move upward, the top ends of the two upper transmission rods 15 first contact the top ends of the inner walls of the two guide grooves 21, and gradually lift the support seat 17 to move upward until the bottom end of the support seat 17 contacts the bottom end of the workpiece to be processed. If the support seat 17 is not in contact with the workpiece to be processed at this time When the flat bottom end of the workpiece fits in with each other, the upper transmission rod 15 below the contacted part remains stationary, while the upper transmission rod 15 below the uncontacted part continues to move upward under the push of the upward upper transmission frame 14, thereby gradually causing the support seat 17 to tilt left and right, and the rotational connection between the spherical head 10, the support seat 17 and the anti-slip seat 19 can also cause the support seat 17 to tilt in the front and rear directions until the top of the support seat 17 fits in with the bottom end surface of the workpiece. At this time, stop rotating the adjusting screw 4, and the support seat 17 that fits in with the bottom end of the workpiece can apply force to the two upper transmission rods 15, and the movement of one upper transmission rod 15 will cause the opposite movement of the other upper transmission rod 15, thereby limiting the movement of the upper transmission rod 15, and the upper transmission rod 15 can also support the support seat 17 left and right, thereby improving the stability of the angle of the support seat 17.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
