Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine clamp with an anti-deviation function. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic to mold thermoplastics or thermosetting plastics into plastic products of various shapes. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it ejected to fill the mold cavity.

[0003] For example, the patent document with application number 202310852114.8 discloses an injection molding machine with anti-deviation function and an anti-deviation method, including an injection molding body, a roller is installed at the bottom of the injection molding body, and a push plate is fixedly installed on the outer wall of the injection molding body, and the push plate is clamped between the No. 2 mold and the No. 1 mold, and the fixed plate is used to drive the roller to squeeze the guide plate, so that the guide plate drives the No. 1 mold to slide inside the connecting plate, so that the first clamping plate and the second clamping plate can be corrected in position when clamped, and the first clamping plate and the second clamping plate are prevented from being offset when clamped, so that when the mechanical parts are worn out after long-term use, it can still ensure that the splicing of the two molds will not deviate, so that the products manufactured by the two molds are more beautiful and the size of the products is maintained.

[0004] Similar injection molding machines may have uneven surfaces on irregular molds, and the center point of balance in the clamping area may also change, resulting in unbalanced force during clamping. The clamping force is difficult to transmit evenly, and the mold is easily offset, which causes cracks, deformation and other problems.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an injection molding machine clamp with an anti-deviation function is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide an injection molding machine clamp with an anti-drift function. Since the surface of an irregular mold may be uneven, and the equilibrium center point of clamping in the clamping area may also change, resulting in unbalanced force during clamping, the clamping force is difficult to transmit evenly, and the mold is easily deviated, and the deviation causes problems such as cracks and deformation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molding machine clamp with an anti-deviation function, comprising a workbench, an electric telescopic column and a clamping assembly, the upper end surface of the workbench is provided with a groove, and the groove is arranged in six groups, the electric telescopic columns are respectively arranged at the four corners of the workbench, and the upper end surfaces of every two groups of the electric telescopic columns are provided with transverse load-bearing plates, and the opposite surfaces of every two groups of the transverse load-bearing plates are provided with longitudinal connecting plates, and threaded holes are provided at both ends of the longitudinal connecting plates, and bolts are provided at both ends of the outer surfaces of the two groups of transverse load-bearing plates, and four groups of bolts are provided, and eight groups of clamping assemblies are provided, and limiting holes are provided on both sides of the outer surfaces of the transverse load-bearing plates and the longitudinal connecting plates, and the limiting holes are arranged in eight groups, and the clamping assembly is arranged on one side of the limiting holes.

[0008] Furthermore, the clamping assembly includes an electric push rod, a clamping plate and a contact gasket. The electric push rod is arranged on one side of the limiting hole, the output end of the electric push rod is provided with a clamping plate, and one side of the clamping plate is provided with a contact gasket.

[0009] Furthermore, the clamping plate and the contact gasket are equal in shape and size, and the eight groups of clamping components correspond to the positions of the eight groups of limiting holes respectively.

[0010] Furthermore, the bolts penetrate through the transverse load-bearing plates and engage with the threaded holes, and the two ends of the longitudinal connecting plate respectively abut against the opposite surfaces of the two groups of transverse load-bearing plates.

[0011] Furthermore, the output end of the electric push rod is connected to the clamping plate by passing through the limiting hole, the contact gasket is made of rubber, and two groups of clamping components are arranged on the outer sides of each group of the transverse load-bearing plates and each group of the longitudinal connecting plates.

[0012] Furthermore, the positions of the six groups of grooves are arranged at equal intervals, and the two ends of the transverse load-bearing plate are respectively welded to the upper end surfaces of the two groups of electric telescopic columns.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by adaptively clamping the four sides of the mold, it can fit the mold with irregular shape, avoiding the situation that the clamping is not firm due to the special shape of the mold, and by adjusting the height of the clamping assembly through the electric telescopic column, it can adapt to molds of different heights and maintain a symmetrical clamping position. The specific contents are as follows:

[0014] A workbench, an electric telescopic column, a transverse load-bearing plate, a longitudinal connecting plate, a limit hole and a clamping component are provided. When the mold is placed on the workbench, the height of the mold can be adjusted by the electric telescopic column. Different production needs can be met by simply adjusting the height of the telescopic column to avoid the displacement of the mold during operation due to height mismatch. Two groups of transverse load-bearing plates and two groups of longitudinal connecting plates are used to form an installation and fixing structure of the clamping component. Eight groups of clamping components are respectively arranged on the outer surfaces of the transverse load-bearing plate and the longitudinal connecting plate, and the output end passes through the surface, so as to adaptively clamp the mold on all sides, effectively cover the irregular mold on all sides, and evenly distribute the clamping force at various parts around the mold, providing multi-point adaptive clamping to firmly clamp the mold in a fixed position to avoid displacement or deformation of the mold.

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, an injection molding machine clamp with an anti-deviating function comprises a workbench 1, an electric telescopic column 3 and a clamping assembly 6. A groove 2 is provided on the upper end surface of the workbench 1. The workbench 1 provides a working area for mold injection. The grooves 2 are provided in six groups. The positions of the six groups of grooves 2 are arranged in an equidistant manner. The grooves 2 are used for the sinking space for the lifting structure to lift the mold. The electric telescopic columns 3 are respectively arranged at the four corners of the workbench 1. The electric telescopic columns 3 realize the lifting function. Stable lifting is ensured by four groups of electric telescopic columns 3. The upper end surfaces of every two groups of electric telescopic columns 3 are provided with transverse load-bearing plates 4. The two ends of the transverse load-bearing plates 4 are respectively welded to the upper end surfaces of the two groups of electric telescopic columns 3. The transverse load-bearing plates 4 provide the function of supporting and bearing the load. The transverse load-bearing plates 4 are ensured by welding. The connection between the horizontal load-bearing plate 4 and the electric telescopic column 3 is firm and reliable. The opposite surfaces of each two groups of horizontal load-bearing plates 4 are provided with longitudinal connecting plates 5. The two ends of the longitudinal connecting plates 5 are respectively abutted against the opposite surfaces of the two groups of horizontal load-bearing plates 4. The two groups of longitudinal connecting plates 5 and the two groups of horizontal load-bearing plates 4 form a mounting structure supported by the clamping assembly 6. Both ends of the longitudinal connecting plates 5 are provided with threaded holes 7. Both ends of the outer surfaces of the two groups of horizontal load-bearing plates 4 are provided with bolts 8. Four groups of bolts 8 are provided. The bolts 8 penetrate the horizontal load-bearing plates 4 and mesh with the threaded holes 7. The bolts 8 mesh with the threaded holes 7, so that the bolts 8 fix the longitudinal connecting plates 5 to the opposite surfaces of the two groups of horizontal load-bearing plates 4, and the bolts 8 are screwed out from the threaded holes 7 to provide a detachable manner.

[0022] The clamping assembly 6 is arranged on one side of the limiting hole 9. There are eight groups of clamping assemblies 6. The eight groups of clamping assemblies 6 provide multi-point clamping to ensure adaptive clamping of the outer surface around the irregular mold. Limiting holes 9 are provided on both sides of the outer surface of the transverse load-bearing plate 4 and the longitudinal connecting plate 5. There are eight groups of limiting holes 9. The eight groups of clamping assemblies 6 correspond to the positions between the eight groups of limiting holes 9 respectively. Two groups of clamping assemblies 6 are arranged on the outer side of each group of transverse load-bearing plates 4 and each group of longitudinal connecting plates 5. The limiting holes 9 facilitate the movement of the output end of the electric push rod 601 and limit it. The clamping assembly 6 includes an electric push rod 601, a clamping plate 602 and a contact gasket 603. The electric push rod 601 is arranged on one side of the limiting hole 9, and the electric push rod 601 provides a uniform pushing force. The output end of the electric push rod 601 is connected to the clamping plate 602 by passing through the limiting hole 9, and is connected to the clamping plate 602 through the output end, so as to realize the reciprocating motion of the clamping plate 602. The output end of the electric push rod 601 is provided with a clamping plate 602, and the clamping plate 602 is used to clamp the mold. A contact gasket 603 is arranged on one side of the clamping plate 602. The material of the contact gasket 603 is rubber. The shape and size of the clamping plate 602 and the contact gasket 603 are equal. The clamping plate 602 increases the buffer with the mold through the contact gasket 603 to prevent the clamping plate 602 from damaging the outer surface of the mold.

[0023] In summary, if Figures 1 to 4As shown, the injection molding machine fixture with anti-deviating function has a mold placed on the groove 2 of the workbench 1 for injection molding. Two groups of horizontal load-bearing plates 4 and the longitudinal connecting plate 5 constitute a U-shaped structure fixedly supported by the clamping assembly 6. The horizontal load-bearing plate 4 is connected to the electric telescopic column 3 by welding, and the bolt 8 is connected and engaged by rotating through the threaded hole 7. When the irregular mold is being injected, the eight groups of clamping assemblies 6 are used to perform multi-point positioning on the surrounding surface. When the height needs to be adjusted, it is only necessary to control the motor in the electric telescopic column 3 to transmit the rotational motion to the internal screw through the transmission device, and the internal screw converts the rotational motion into linear motion. By controlling the rotation direction and speed of the motor, when the mold needs to be clamped, the electric push rod 601 is controlled to be extended and retracted in the limit hole 9, and the clamping plate 602 is contacted with the mold using the contact gasket 603. The eight groups of clamping assemblies 6 are fixed in this way.
