Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a precision machining fixture for injection molding machine frame. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. Currently, when welding the frame of an injection molding machine, special welding fixtures are usually required for clamping. However, the existing precision machining fixtures for the injection molding machine frame are not easy to adjust in height during machining, and the height difference between the clamping plates and the frame after adjustment can easily occur, resulting in the fixture being too low to hold the machine or too high and obstructing the frame. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the prior art by proposing a precision machining fixture for injection molding machine frames.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A precision machining fixture for an injection molding machine frame includes a base frame and a machine body. The base frame has a mounting groove; a base plate is movably connected to the mounting groove; the machine body is placed on the base plate; clamping plates are movably connected to both sides of the mounting groove; the lower ends of the two clamping plates are fitted against the upper ends of the base plate; a cylinder is connected to the outer side of each of the two clamping plates; the two clamping plates are clamped to both sides of the machine body via the cylinders; a connecting rod is connected to the output end of the cylinder; a moving groove matching the connecting rod is provided on the outer side of the clamping plate; the moving groove is vertically arranged; the clamping plate is movably engaged with the connecting rod via the moving groove.

[0006] Preferably, the base frame is also movably connected to the two sides away from the cylinder one; the outer side of the abutment block is connected to the cylinder two; the abutment block is clamped to the machine body through the cylinder two.

[0007] Preferably, the bottom of the base plate is connected to a cylinder three; the base plate moves up and down in the mounting groove via the cylinder three.

[0008] Preferably, the sides of the base plate are connected to locking blocks; the base frame is provided with locking slots that match the locking blocks; the locking slots are vertically arranged and communicate with the mounting slots.

[0009] Preferably, the height of the moving slot is not less than the height of the card slot.

[0010] Compared with the prior art, this utility model provides a precision machining fixture for injection molding machine frames, which has the following beneficial effects:

[0011] This precision-machined fixture for the injection molding machine frame uses movable clamping plates on both sides of the mounting slot to abut and fix the machine body. It works in conjunction with abutment blocks to prevent the machine body from moving laterally. The clamping plates are also equipped with movable grooves, allowing them to move upwards with the base plate. This prevents the machine body from being too high, which would result in an insufficient contact area between the clamping plates and the machine body. It can also clamp and fix the machine body even when it is low. The operation is simple and convenient. Attached Figure Description

[0016] The following will refer to Figure 1-3 This invention describes a specific implementation of a precision machining fixture for an injection molding machine frame, comprising a base frame 10 and a machine body 11. The base frame 10 has a mounting groove 21; a base plate 22 is movably connected within the mounting groove 21; the machine body 11 is placed on the base plate 22; clamping plates 23 are movably connected to both sides of the mounting groove 21; the lower ends of the two clamping plates 23 are fitted against the upper ends of the base plate 22; cylinders 24 are connected to the outer sides of the two clamping plates 23; the two clamping plates 23 are clamped to both sides of the machine body 11 by the cylinders 24; a connecting rod 25 is connected to the output end of the cylinders 24; a moving groove 26 matching the connecting rod 25 is provided on the outer side of the clamping plate 23; the moving groove 26 is vertically arranged; the clamping plate 23 is movably engaged with the connecting rod 25 through the moving groove 26. When in use, the machine body 11 can be placed on the base plate 22 first, and then the height of the base plate 22 can be adjusted to the required position. As the base plate 22 rises, it will drive the clamping plate 23 to move upward. In order to prevent the connecting rod 25 from colliding with the clamping plate 23, the cross-section of the moving groove 26 is T-shaped, and the end of the connecting rod 25 should be correspondingly T-shaped. The clamping plate 23 is then fixedly clamped to the machine body 11 by the cylinder 24, and the clamping plate 23 can always be close to the lower end of the machine body 11.

[0017] To prevent the other two sides of the machine body 11 from being fixed, abutment blocks 27 are movably connected to the two sides of the base frame 10 away from cylinder 24; cylinder 28 is connected to the outer side of the abutment block 27; the abutment block 27 is clamped to the machine body 11 by the cylinder 28.

[0018] The bottom of the base plate 22 is connected to a cylinder 31; the base plate 22 moves up and down in the mounting groove 21 via the cylinder 31; the sides of the base plate 22 are connected to locking blocks 32; the base frame 10 is provided with locking grooves 33 that match the locking blocks 32, and the locking grooves 22 restrict the up and down movement of the base plate 22 to prevent the base plate 22 from tilting during movement; the locking grooves 33 are vertically arranged and communicate with the mounting groove 21; and the height of the moving groove 26 is not less than the height of the locking grooves 33, so that the clamping plate 23 can be effectively clamped.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
