Description

Technical Field

[0001] The present application relates to the technical field of injection mold processing, and in particular to a clamping assembly for injection mold processing. Background Art

[0002] An injection mold is a tool used to process plastic products during the injection molding process. It heats and melts the plastic material and injects it into the mold. After cooling and solidifying, it forms a mold for the desired plastic product. The injection molded product is taken out after the injection molding is completed in the injection mold.

[0003] Since the product in the injection mold has a high temperature after injection molding, the injection molded product in the mold is generally clamped with tongs. The contact area of ​​the two tongs' legs on the product surface is relatively small, and the pressure generated may cause damage to the product surface and may cause the tongs to slip from the product surface during the clamping process. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to provide a clamping assembly for injection mold processing to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides a clamping assembly for injection mold processing, including a device frame, the outer surface of the device frame is fixedly connected to an armrest frame, the outer surface of the device frame is provided with a plurality of groups of slide grooves, the bottom of the inner wall of the device frame is rotatably connected to a screw rod, the top of the screw rod is fixedly connected to a knob, and a triangular clamping mechanism is arranged on the device frame.

[0006] Preferably, the triangular clamping mechanism includes a fixed block fixedly connected to the outer surface of the device frame, and the inner surface of the fixed block is rotatably connected to the first frame shaft. Through the triangular clamping mechanism, multiple groups of upper and lower clamps on the three groups of deflection frames can be evenly clamped on the outer surface of the mold product.

[0007] Preferably, the outer surface of the first frame shaft is rotatably connected to a swing frame, and the end of the swing frame away from the first frame shaft is rotatably connected to the second frame shaft.

[0008] Preferably, a tripod is provided on the threaded sleeve on the outer surface of the screw rod, and an end shaft is rotatably connected to the end of the tripod. There are three groups of end shafts, and three groups of corresponding swing frames and deflection frames are also provided.

[0009] Preferably, the outer surface of the end shaft is rotatably connected to a deflection frame, the inner surface of the deflection frame is rotatably connected to the outer surface of the second frame shaft, and a lower clamp is provided at the bottom of the deflection frame.

[0010] Preferably, a fixing frame is fixedly connected to the inner side of the deflection frame, and an upper clamping piece is provided at one end of the fixing frame away from the deflection frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The clamping assembly for injection mold processing adopts multiple sets of clamping clips in the process of clamping the product, which are evenly distributed at different positions of the product. By increasing the clamping area, more uniform pressure distribution can be achieved, reducing the pressure concentration on the product surface and reducing the risk of product surface damage.

[0013] 2. The clamping assembly for injection mold processing is designed with multiple sets of upper and lower clamping pieces, which makes its contact area with the product larger, has more clamping points, and has higher clamping stability, which can effectively prevent the tongs from slipping off the product surface during the clamping process, ensuring that the product is safely clamped out.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-3 A clamping assembly for injection mold processing includes a device frame 1, an armrest frame 2 is fixedly connected to the outer surface of the device frame 1, a plurality of slide grooves 3 are opened on the outer surface of the device frame 1, a screw rod 4 is rotatably connected to the bottom of the inner wall of the device frame 1, a knob 5 is fixedly connected to the top of the screw rod 4, and a triangular clamping mechanism is arranged on the device frame 1.

[0020] Through the above technical solution, when using the device, the armrest frame 2 can be held, and the rotating knob 5 can drive the screw 4 to rotate. The three groups of deflection frames 12 can be gradually retracted through the triangular clamping mechanism, and the lower clamping piece 13 and the upper clamping piece 15 can be used to clamp and take out the product processed in the mold.

[0021] Specifically, the triangular clamping mechanism includes a fixing block 6 fixedly connected to the outer surface of the device frame 1 , and the inner surface of the fixing block 6 is rotatably connected to the first frame shaft 7 .

[0022] Through the above technical solution, the swing frame 8 can cooperate with the deflection frame 12 to drive the deflection frame 12 during the process of rotating along the first frame axis 7.

[0023] Specifically, the outer surface of the first frame shaft 7 is rotatably connected to the swing frame 8 , and one end of the swing frame 8 away from the first frame shaft 7 is rotatably connected to the second frame shaft 9 .

[0024] Through the above technical solution, the three sets of swing frames 8 are respectively arranged on the periphery of the tripod 10 and are evenly distributed in coordination with the deflection frames 12 at corresponding positions.

[0025] Specifically, a tripod 10 is threadedly sleeved on the outer surface of the screw rod 4 , and an end shaft 11 is rotatably connected to the end of the tripod 10 .

[0026] Through the above technical solution, when the tripod 10 moves up and down, the three groups of end shafts 11 will drive the deflection frames 12 at corresponding positions to deflect synchronously.

[0027] Specifically, the outer surface of the end shaft 11 is rotatably connected to the deflection frame 12 , the inner surface of the deflection frame 12 is rotatably connected to the outer surface of the second frame shaft 9 , and a lower clamping piece 13 is provided at the bottom of the deflection frame 12 .

[0028] Through the above technical solution, the lower clamping piece 13 at the bottom end of the deflection frame 12 is located at a relatively lower position than the outer surface of the product when clamping the product.

[0029] Specifically, a fixing frame 14 is fixedly connected to the inner side of the deflection frame 12 , and an upper clamping piece 15 is provided at one end of the fixing frame 14 away from the deflection frame 12 .

[0030] Through the above technical solution, the fixed frame 14 at the middle part of the deflection frame 12 squeezes and supports the product through the upper clamping piece 15, and the clamping position of the upper clamping piece 15 is located at a relatively upper position of the product.

[0031] Working principle: When the device clamps the product that has been injection molded in the mold, first hold the handrail frame 2, then rotate the knob 5 to drive the screw 4 to rotate. During this process, the tripod 10 will move downward along the surface of the screw 4, and the three ends of the tripod 10 will slide downward along the slide groove 3. During the downward movement, the tripod 10 will pull the deflection frame 12 at the corresponding position downward through the end shaft 11. At this time, due to the relative restriction of the swing frame 8, the swing frame 8 will rotate along the first frame axis 7 and the second frame axis 9. At the same time, the bottom ends of the three groups of swing frames 8 will be relatively close, and drive the three groups of deflection frames 12 to rotate along the end shaft 11 at the corresponding position. During this process, the bottom ends of the three groups of deflection frames 12 will gradually close together, and link the three groups of fixed frames 14 to approach each other. Finally, the three groups of lower clamps 13 will clamp the product relatively. The lower part of the product, and the three groups of upper clamps 15 will clamp at the relatively upper part of the product. Multiple groups of evenly distributed clamps clamp the product simultaneously to stably and safely clamp and take out the product. Compared with the traditional fire tongs clamping the product, only two clamp feet are in contact with the product surface, and the contact area is relatively small, which can easily cause excessive local pressure and cause product damage. The present application adopts multiple groups of clamping clamps, which are evenly distributed at different positions of the product. By increasing the clamping area, a more uniform pressure distribution can be achieved, reducing the pressure concentration on the product surface, reducing the risk of damage to the product surface, and the contact area between the clamps and the product is larger, the clamping points are more, and the clamping stability is higher, which can effectively prevent the fire tongs from slipping from the product surface during the clamping process, ensuring that the product is safely clamped out.

[0032] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
