Description

Technical Field

[0001] The utility model relates to the technical field of precision molds, in particular to a precision mold with a precise positioning function. Background Art

[0002] Precision molds are high-precision, high-quality molds used to produce a variety of precision parts and products. They are usually made of high-grade steel and other materials, and require strict dimensional control and surface treatment during the manufacturing process to ensure their accuracy and service life.

[0003] When processing existing precision molds, the base on which the mold is placed is often subject to extrusion and impact from the top. After long-term use, the base is easily damaged and cracked, which will cause dimensional deviations when processing precision parts and affect the processing effect. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a precision mold with a precise positioning function.

[0005] The utility model is implemented by the following technical scheme: a precision mold with a precise positioning function, comprising a support table, a shock absorbing component is provided in the middle of the upper surface of the support table, guide rail frames are slidably connected to both sides of the upper surface of the support table, a first slide groove is provided in the middle of the inner wall of the guide rail frame, and a first slider is slidably connected to the inside of the first slide groove;

[0006] The shock-absorbing component includes a placement groove, which is opened in the middle of the upper surface of the support platform. The inner bottom wall of the placement groove is fixedly connected with a shock-absorbing base plate. There are four shock-absorbing base plates, which are respectively fixedly connected to the four corners of the inner bottom wall of the placement groove. The upper surface of the shock-absorbing base plate is fixedly connected with a telescopic spring, and the bottom of the telescopic spring is fixedly connected with a contact cross plate.

[0007] Through the above technical solution, the contact cross plate is connected to the top mold base. When the square pressing piece moves downward to process the object inside the mold base, the mold base is squeezed by the square pressing piece and moves downward. The pressure is relieved by the telescopic spring, thereby reducing the impact force from top to bottom, thereby preventing the mold base from being squeezed by the square pressing piece for a long time, which may easily cause damage to the surface of the mold base. The subsequent maintenance cost of the mold base by the staff is reduced, and the service life of the parts is extended.

[0008] As a further improvement of the above solution, the upper surface of the contact horizontal plate is fixedly connected to a mold base, and both sides of the outer surface of the mold base are fixedly connected to extension blocks.

[0009] Through the above technical solution, the mold base is a device for fixing and supporting the mold, which is usually made of metal or other solid materials and has sufficient weight and stability to ensure the safety and accuracy of the mold during injection molding, stamping or other molding processes.

[0010] As a further improvement of the above solution, a positioning bolt is inserted into the interior of the extension block, the bottom end of the positioning bolt is inserted into the interior of the support platform, and the top of the positioning bolt is threadedly connected with a hexagonal nut.

[0011] Through the above technical solution, the mold base can be positioned and fixed by the hexagonal nuts and positioning bolts, so as to avoid the mold base shifting and shaking during operation, which affects the subsequent processing efficiency.

[0012] As a further improvement of the above solution, a pressing plate is fixedly connected to one side of the first sliding block, and a square pressing piece is fixedly connected to the middle of the lower surface of the pressing plate.

[0013] Through the above technical solution, the pressing plate drives the square pressing piece to rise and fall inside the first slide groove, exerting pressure on the mold base, thereby processing the internal mold. Sliding inside the first slide groove can prevent the square pressing piece from deviating from the motion trajectory, thereby improving the accuracy of mold processing.

[0014] As a further improvement of the above solution, a connecting rod is fixedly connected to the top of the guide rail frame, and a top plate is fixedly connected to the top of the connecting rod.

[0015] Through the above technical solution, the connecting rod can support and fix the top plate, improve the stability of the top plate when it is placed, and prevent the top plate from falling and shaking.

[0016] As a further improvement of the above solution, a bearing plate is fixedly connected to one side of the lower surface of the top plate, and a servo motor is fixedly mounted on the surface of the bearing plate by bolts.

[0017] Through the above technical solution, the bearing plate supports the servo motor, and the servo motor is installed by bolts, which is convenient for personnel to disassemble and assemble it and perform maintenance in time.

[0018] As a further improvement of the above scheme, the output end of the servo motor is fixedly connected to a screw, the bottom end of the screw is threadedly connected to a sleeve, the bottom end of the sleeve is fixedly connected to the upper surface of the pressing plate, and the four corners of the lower surface of the support platform are fixedly connected to a magnetic base.

[0019] Through the above technical solution, the servo motor is started to drive the screw to rotate, and the screw drives the pressing plate to rise and fall inside the first slide groove through the sleeve, so as to process the mold inside the mold base. The magnetic base can improve the stability of the device when it is fixed and avoid displacement and shaking of the device.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a shock-absorbing component, when the square pressing piece moves downward to process the object inside the mold base, the mold base is squeezed by the square pressing piece and moves downward, and the pressure is relieved by the telescopic spring, thereby reducing the impact force from top to bottom, avoiding the mold base being squeezed by the square pressing piece for a long time, which may easily cause damage to the surface of the mold base, and reducing the subsequent maintenance cost of the mold base by personnel. The pressing plate drives the square pressing piece to rise and fall inside the first slide groove, so that the square pressing piece will not deviate from the motion trajectory, thereby improving the accuracy of mold processing.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Example:

[0031] Please combine Figure 1-5A precision mold with a precise positioning function in this embodiment includes a support platform 1, a shock absorbing component 2 is provided in the middle of the upper surface of the support platform 1, guide rail frames 3 are slidably connected to both sides of the upper surface of the support platform 1, a first slide groove 4 is provided in the middle of the inner wall of the guide rail frame 3, and a first slider 5 is slidably connected to the inside of the first slide groove 4;

[0032] The shock-absorbing component 2 includes a placement groove 201, which is opened in the middle of the upper surface of the support platform 1. The inner bottom wall of the placement groove 201 is fixedly connected with a shock-absorbing base plate 202. There are four shock-absorbing base plates 202, which are respectively fixedly connected to the four corners of the inner bottom wall of the placement groove 201. The upper surface of the shock-absorbing base plate 202 is fixedly connected with a telescopic spring 203, and the bottom of the telescopic spring 203 is fixedly connected with a contact cross plate 204. The contact cross plate 204 is connected to the top mold base 6. When the square pressing piece 11 moves downward to process the internal object of the mold base 6, the mold base 6 is squeezed by the square pressing piece 11 and moves downward. The telescopic spring 203 is used to relieve the pressure and reduce the impact force from top to bottom, so as to avoid the mold base 6 being squeezed by the square pressing piece 11 for a long time, which may easily cause damage to the surface of the mold base 6, reduce the subsequent maintenance cost of the mold base 6 by the staff, and extend the service life of the parts.

[0033] The upper surface of the contact cross plate 204 is fixedly connected to a mold base 6, and extension blocks 7 are fixedly connected to both sides of the outer surface of the mold base 6. The mold base 6 is a device used to fix and support the mold. It is usually made of metal or other solid materials and has sufficient weight and stability to ensure the safety and accuracy of the mold during injection molding, stamping or other molding processes.

[0034] A positioning bolt 8 is inserted into the interior of the extension block 7, and the bottom end of the positioning bolt 8 is inserted into the interior of the support platform 1. The top of the positioning bolt 8 is threadedly connected with a hexagonal nut 9. The mold base 6 can be positioned and fixed by the hexagonal nut 9 and the positioning bolt 8 to avoid the mold base 6 from shifting and shaking during operation, which affects the subsequent processing efficiency.

[0035] A pressing plate 10 is fixedly connected to one side of the first sliding block 5, and a square pressing piece 11 is fixedly connected to the middle of the lower surface of the pressing plate 10. The pressing plate 10 drives the square pressing piece 11 to rise and fall inside the first sliding groove 4, exerting pressure on the mold base 6, thereby processing the internal mold. Sliding inside the first sliding groove 4 can prevent the square pressing piece 11 from deviating from the motion trajectory, thereby improving the accuracy of mold processing.

[0036] The top of the guide rail frame 3 is fixedly connected with a connecting rod 12, and the top of the connecting rod 12 is fixedly connected with a top plate 13. The connecting rod 12 can support and fix the top plate 13, improve the stability of the top plate 13 when it is placed, and prevent the top plate 13 from falling and shaking.

[0037] A bearing plate 14 is fixedly connected to one side of the lower surface of the top plate 13, and a servo motor 15 is fixedly installed on the surface of the bearing plate 14 by bolts. The bearing plate 14 supports the servo motor 15, and the servo motor 15 is installed by bolts, which is convenient for personnel to disassemble and assemble it and perform maintenance in time.

[0038] The output end of the servo motor 15 is fixedly connected with a screw rod 16, the bottom end of the screw rod 16 is threadedly connected with a sleeve 17, the bottom end of the sleeve 17 is fixedly connected to the upper surface of the pressing plate 10, and the four corners of the lower surface of the support platform 1 are fixedly connected with a magnetic base 18. By starting the servo motor 15 to drive the screw rod 16 to rotate, the screw 16 drives the pressing plate 10 to rise and fall inside the first slide groove 4 through the sleeve 17, thereby processing the mold inside the mold base 6. The magnetic base 18 can improve the stability of the device when it is fixed and prevent the device from shifting and shaking.

[0039] The implementation principle of a precision mold with a precise positioning function in the embodiment of the present application is as follows: a person starts the servo motor 15 to drive the screw 16 to rotate, and the screw 16 drives the pressing plate 10 to rise and fall inside the first slide groove 4 through the sleeve 17, exerting pressure on the mold base 6, thereby processing the internal mold. Sliding inside the first slide groove 4 can prevent the square pressing piece 11 from deviating from the motion trajectory, thereby improving the accuracy of mold processing. The contact cross plate 204 is connected to the top mold base 6. When the square pressing piece 11 moves downward to process the object inside the mold base 6, the mold base 6 is squeezed by the square pressing piece 11 and moves downward. The telescopic spring 203 is used to relieve the pressure, reduce the impact force from top to bottom, and avoid the mold base 6 being squeezed by the square pressing piece 11 for a long time, which may easily cause damage to the surface of the mold base 6, reduce the subsequent maintenance cost of the mold base 6 by the staff, and extend the service life of the parts.

[0040] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
