Description

Technical Field

[0001] The utility model relates to the technical field of fixed tooling, in particular to a tooling for polishing and shaping injection molded parts. Background Art

[0002] In the traditional injection molding process, after the injection molding is completed, because the injection molding material is soft at high temperature, the product needs to be shaped after being taken out of the injection molding machine to ensure that the product's appearance meets the composite requirements. After shaping, the injection molding will have some burrs, so the burrs need to be polished.

[0003] For example, the Chinese patent "CN220330850U" discloses "an injection molding grinding device with a grinding force adjustment function", in which two sets of clamps are driven to move in opposite directions through the screw connection of the bidirectional threaded rod and the threaded ring, and the clamps are moved and limited through the sliding connection of the slide groove and the slider, and the position of the workpiece is fixed by the two sets of clamps to achieve the position fixation of the workpiece. However, since the clamp is a planar structure, when clamping a columnar workpiece, due to the small contact surface, the stability during grinding cannot be guaranteed, and other tooling needs to be replaced for installation and clamping, which indirectly increases the cost. Utility Model Content

[0004] In view of the deficiencies existing in the prior art, the utility model provides a tool for polishing and shaping injection molded parts, which solves the problem that when the clamping plate of the polishing device in the prior art clamps a cylindrical workpiece, the stability during polishing cannot be guaranteed due to the small contact surface, and other tooling needs to be replaced for installation and clamping, which indirectly increases the cost.

[0005] According to the embodiment of the utility model, the utility model adopts the following technical solution:

[0009] The driving assembly is connected between the two clamping plates and is used to drive the two clamping plates to move closer or farther away so as to fix or release the injection molded part.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] With the cooperation of the two clamping plates and the driving assembly, the workpiece can be pressed and clamped by bringing the clamping plates closer to each other, thereby ensuring stability during workpiece shaping and grinding and improving quality. When grinding and working on a columnar workpiece, the two auxiliary plates arranged in the clamping plates can be moved out of the clamping plates by adjusting the adjusting parts in the assembly, so that the two auxiliary plates have a certain angle. During the movement of the two clamping plates, the four auxiliary plates are simultaneously engaged with the circumference of the columnar workpiece, thereby increasing the contact area when clamping the columnar workpiece, thereby ensuring the stability of its fixation. While ensuring stability, there is no need to replace other tooling, thereby saving cost and time and improving efficiency.

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, the embodiment of the utility model provides an injection molded part grinding and shaping tool, comprising:

[0026] Two clamping plates 5 arranged opposite to each other;

[0027] An adjusting assembly, comprising two auxiliary plates 11 rotatably disposed in the clamping plate 5 and an adjusting member connected between the two auxiliary plates 11, the adjusting member being used to adjust the angle between the two auxiliary plates 11 so that the two auxiliary plates 11 protrude from or are accommodated in the clamping plate 5; and

[0028] The driving assembly is connected between the two clamping plates 5 and is used to drive the two clamping plates 5 to move closer or farther away so as to fix or release the injection molded part.

[0029] In the embodiment of the utility model, the two clamping plates 5 are driven to approach each other by a driving assembly, such as Figure 5 As shown, the rectangular workpiece can be quickly fixed. The edge of the clamping plate 5 directly contacts the rectangular workpiece to ensure the stability of its fixation. When grinding and beating a columnar workpiece, Figure 4 As shown, the two auxiliary plates 11 arranged in the clamping plate 5 can be moved out of the clamping plate 5 by adjusting the adjusting parts in the assembly, so that the two auxiliary plates 11 have a certain angle. During the movement of the two clamping plates 5, the four auxiliary plates 11 are simultaneously engaged with the circumference of the columnar workpiece, thereby increasing the contact area when clamping the columnar workpiece, thereby ensuring the stability of its fixation. Moreover, when the rectangular workpiece is clamped and fixed subsequently, the auxiliary plates 11 can be stored in the clamping plate 5 again through the adjusting parts. While ensuring stability, there is no need to replace other tooling, thereby saving cost and time and improving efficiency.

[0030] Based on the above scheme, if Figure 3As shown, the adjusting member includes a second screw rod 7 rotatably arranged on the clamping plate 5, two driving blocks 8 slidably arranged on the clamping plate 5 and respectively arranged at the two ends of the second screw rod 7, and an adjusting rod 9 rotatably arranged at the end of the driving block 8, and one end of the adjusting rod 9 is movably connected to the auxiliary plate 11. Specifically, when the two auxiliary plates 11 set by the adjusting member are adjusted, the second screw rod 7 is rotated so that the second screw rod 7 rotates to drive the driving blocks 8 at both ends to approach each other, so that the angle between the driving blocks 8 and the adjusting rod 9 connected thereto becomes larger, thereby lifting the auxiliary plate 11 through the top of the adjusting rod 9, so that the angle between the two auxiliary plates 11 becomes smaller, thereby completing the adjustment. When the auxiliary plate 11 needs to be stored for clamping a rectangular workpiece, the second screw rod 7 is reversed so that the driving blocks 8 at both ends of the second screw rod 7 are moved away from each other, thereby reducing the angle between the driving blocks 8 and the adjusting rod 9 connected thereto, and the two corresponding auxiliary plates 11 can be stored in the clamping plate 5 at the same time. After storage, the two auxiliary plates 11 still have a certain angle, so that it is convenient to move them out for use later.

[0031] Based on the above scheme, if Figure 1 and Figure 2 As shown, the driving assembly includes a base 1, a first screw rod 6 rotatably arranged on the base 1, and two moving blocks 2 slidably arranged on the base 1 and respectively connected to the two ends of the first screw rod 6, and the two moving blocks 2 are respectively connected to the two clamping plates 5. Specifically, when the two clamping plates 5 are driven to move by the driving assembly, the first screw rod 6 is rotated to drive the moving blocks 2 at both ends to approach each other, so that the rectangular workpiece is pressed and fixed by the two clamping plates 5, or the columnar workpiece is pressed and fixed by the opened auxiliary plate 11. When releasing the fixation, the first screw rod 6 is reversed to make the two clamping plates 5 move away from each other. Moreover, the first screw rod 6 and the second screw rod 7 are both provided with a knob 4, which can be conveniently operated manually by the knob 4, saving manpower.

[0032] Specifically, the clamping plate 5 is fixedly provided with a rotating rod 3, and the rotating rod 3 is rotatably arranged on the moving block 2. Under the action of the rotating rod 3, the clamping plate 5 can be rotated on the moving block 2. When the two clamping plates 5 clamp the workpiece, the workpiece can be rotated between the two moving blocks 2, which is convenient for all-round grinding. In the rotation drive of the clamping plate 5, a motor can be arranged on the rotating rod 3 of one of the clamping plates 5, and the rotation and stopping of the workpiece can be controlled by the motor. The nut can also be fixed by tightening the nut on the rotating rod 3, and the rotation stopping of the clamping plate 5 can also be achieved.

[0033] Specifically, both auxiliary plates 11 are provided with anti-skid pads 10, which can increase the contact friction between the auxiliary plates 11 and the columnar workpiece, thereby improving a certain stability. The anti-skid pads 10 can be one of rubber pads, film pads and foam pads.

[0034] Specifically, Figure 1 As shown, the base 1 is provided with a plurality of mounting seats 12, and each of the mounting seats 12 is provided with through holes for bolts to pass through. Bolts can be passed through the through holes of each mounting seat 12 to fix the base 1 on the work surface to ensure overall stability.

[0035] In summary, under the action of the two clamping plates 5, the present scheme can quickly clamp the rectangular workpiece while ensuring the stability after clamping. When clamping the columnar workpiece, the second screw 7 can be rotated to drive the auxiliary plate 11 to rotate the clamping plate 5 with the rotating shaft as the axis through the driving blocks 8 that are close to each other, so that the two clamping plates 5 form a certain angle, and the circumference of the columnar workpiece can be fit in this angle, thereby increasing the contact area of ​​the columnar workpiece after clamping, indirectly ensuring the stability of its clamping, ensuring the quality of grinding, and switching the shape at any time for use with workpieces of different shapes. There is no need to replace other tooling structures, which improves work efficiency while reducing costs.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
