Description

Technical Field

[0001] The present application relates to the field of mold bases, and in particular to a mold base with stable mold clamping. Background Art

[0002] The die frame is the support of the mold. For example, the part that combines and fixes the various parts of the mold according to a certain rule and position on the die-casting machine and enables the mold to be installed on the die-casting machine for work is called the die frame. It consists of an ejection mechanism, a guide mechanism, a pre-reset mechanism, a die foot pad, and a seat plate.

[0003] The movable platen part of the existing stamping die is generally fixed on the slide of the press, and is moved by the press to close the mold to complete the stamping. However, it was found during production that after multiple mold closings, the end face of the movable platen facing the fixed platen would be worn, resulting in the relative end faces of the movable platen and the fixed platen not fitting tightly during subsequent mold closing, thereby affecting the yield of metal stamping parts, which needs to be improved. Utility Model Content

[0004] In order to improve the problem that the end surface of the fixed mold plate is damaged, resulting in the relative end surfaces of the movable mold plate and the fixed mold plate not fitting tightly during mold closing, the present application provides a mold frame with stable mold closing.

[0005] The present application provides a mold frame with stable mold clamping, which adopts the following technical solution:

[0006] A mold frame with stable mold closing comprises a frame body, a fixed mold plate arranged on the frame body and a movable mold plate slidably connected to the frame body, the frame body is provided with a driving cylinder, the driving cylinder drives the movable mold plate to move in a direction close to or away from the fixed mold plate, a sliding column is provided on the side of the fixed mold plate facing the movable mold plate, a sliding groove for accommodating the sliding column is provided on the side of the movable mold plate facing the fixed mold plate, mold closing protrusions are provided at the four corners of the fixed mold plate, and a mold closing groove for accommodating the mold closing protrusion is provided on the side of the movable mold plate facing the fixed mold plate, when the mold closing protrusion is accommodated in the mold closing groove, the movable mold plate fits with the opposite side of the fixed mold plate.

[0007] By adopting the above technical scheme, a sliding column and a sliding groove are arranged to cooperate with each other, and the sliding column is used to guide the movable template and the fixed template to avoid errors when the mold is closed, and the relative end faces of the movable template and the fixed template are fitted together through the cooperation of the mold closing protrusion and the mold closing groove. The mold frame with stable mold closing can stabilize the mold closing of the movable template and the fixed template through the guidance of the sliding column and the positioning of the mold closing protrusion, and make the movable template and the fixed template fit tightly.

[0008] Optionally, an elastic buffer column is provided on the sliding column, and the elastic buffer column is sleeved on the sliding column. A buffer groove for accommodating the elastic buffer column is opened in the sliding groove. When the end face of the elastic buffer column away from the fixed template abuts against the groove wall of the buffer groove, the movable template fits against the opposite side of the fixed template.

[0009] By adopting the above technical solution, an elastic buffer column is arranged to abut against the groove wall of the buffer groove. When the movable mold plate fits the fixed mold plate, part of the impact force is absorbed by the elastic buffer column, thereby reducing the impact force, reducing losses, protecting the movable mold plate and the fixed mold plate, and extending the service life of the mold.

[0010] Optionally, a limit member is provided on the fixed template, and the limit member includes a fixing rod arranged on the fixed template and an elastic sheet arranged on the fixing rod, the elastic sheet is located on both sides of the elastic buffer column, and the side of the elastic sheet facing away from the fixed template is abutted against the side of the elastic buffer column facing the fixed template.

[0011] By adopting the above technical solution, an elastic sheet is provided for the elastic buffer column to abut against. When the elastic buffer column is subjected to impact force and tends to move downward, the elastic sheet absorbs the buffer force, so that most of the impact force during mold closing is offset and absorbed by the cooperation of the elastic buffer column and the elastic sheet, thereby protecting the movable mold plate and the fixed mold plate.

[0012] Optionally, a fixed seat is provided on the frame, and the fixed seat includes a fixed plate and a fixed block arranged on the fixed plate, the fixed plate is fixed to the output shaft of the driving cylinder, and a fixing screw is provided on the fixed plate, and the fixing screw is used to fix the movable template to the fixed block.

[0013] By adopting the above technical solution, a fixed screw is set to fix the movable template on the fixed seat, so that the movable template is set on the frame, and the movable template on the fixed seat is fixed by the fixed screw. When replacing other movable templates, only a few screws need to be removed, which is more convenient.

[0014] Optionally, a mounting seat is provided on the frame, the fixed template is arranged on the mounting seat to be arranged on the frame, and a mounting screw is provided on the mounting seat, and the mounting screw is used to fix the fixed template on the mounting seat.

[0015] By adopting the above technical solution, mounting screws are set to fix the fixed template on the mounting seat, so that the fixed template is set on the frame, and the fixed template on the mounting seat is fixed by the mounting screws. When replacing other fixed templates, only a few screws need to be removed, which is more convenient.

[0016] Optionally, the frame is provided with a fixing protrusion, and the mounting seat is provided with a fixing groove for accommodating the fixing protrusion, and the fixing protrusion is accommodated in the fixing groove so that the mounting seat is fixed to the frame.

[0017] By adopting the above technical solution, the fixing protrusion is arranged to be accommodated in the fixing groove, so that the mounting seat is limited on the frame, thereby preventing the mounting seat from moving and making the mounting seat relatively fixed on the frame.

[0018] Optionally, positioning protrusions are provided at four edges of the fixed template, and positioning grooves for accommodating the positioning protrusions are opened on the movable template.

[0019] By adopting the above technical solution, the positioning protrusion is arranged to be accommodated in the positioning groove, so as to avoid deviation in the fitting between the movable mold plate and the fixed mold plate when the mold is closed.

[0020] Optionally, the mold clamping protrusion is provided with a chamfer.

[0021] By adopting the above technical solution, the chamfer is set to make the edge of the mold clamping protrusion smoother, so that the mold clamping protrusion can be smoothly accommodated in the mold clamping groove during mold clamping.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The sliding column and the sliding groove are matched, and the sliding column is guided to avoid errors when the movable platen and the fixed platen are fitted together during mold closing, and the mold closing protrusion and the mold closing groove are matched to make the opposite end faces of the movable platen and the fixed platen fit together. The mold frame with stable mold closing can stabilize the mold closing of the movable platen and the fixed platen through the guidance of the sliding column and the positioning of the mold closing protrusion, and make the movable platen and the fixed platen fit closely;

[0024] 2. Set the elastic buffer column to abut against the groove wall of the buffer groove. When the movable platen fits the fixed platen, part of the impact force is absorbed by the elastic buffer column, thereby reducing the impact force, reducing the loss, protecting the movable platen and the fixed platen, and extending the service life of the mold;

[0025] 3. The positioning protrusion is arranged to be accommodated in the positioning groove to avoid deviation in the fit between the movable platen and the fixed platen during mold closing;

[0026] 4. Set the chamfer to make the edge of the mold clamping protrusion smoother, so that the mold clamping protrusion can be smoothly accommodated in the mold clamping groove during mold clamping. BRIEF DESCRIPTION OF THE DRAWINGS
