Description

Technical Field

[0001] The utility model relates to a guide mechanism, in particular to a mold base side-prevention guide mechanism. Background Art

[0002] In recent years, with the increasingly fierce competition in the automobile market, major automobile manufacturers have turned their attention to the automobile's own covers and related stamping parts (hereinafter collectively referred to as parts) in the direction of developing and researching new models, and have higher and higher requirements for them. Parts tend to be complex, high-strength, and have a wide variety of complex parts and unique shapes. It is necessary to prevent lateral forces in the mold to ensure the stable molding of the parts. Since the appearance of the side block must maintain a certain ratio with the mold size, it has a great impact on the mold space, thereby increasing the mold cost. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a mold base side-preventing guide mechanism, which effectively solves the problems mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes an upper die seat, an upper key block, an upper anti-side block, a lower die seat, a lower key block, a lower anti-side block, an upper die wear-resistant plate, a lower die wear-resistant plate, a guide sleeve, a guide column, a first bolt, a first bolt hole, a second bolt, a third bolt, a keyway and a fourth bolt, the bottom of the upper die seat is equipped with an upper anti-side block through a first bolt, the upper die seat is equipped with an upper key block, the upper die seat is equipped with a guide column on one side of the upper anti-side block, the lower anti-side block is equipped with a fourth bolt, the lower die seat is equipped with a lower key block, one side of the upper anti-side block is equipped with an upper die wear-resistant plate through a second bolt, one side of the lower anti-side block is equipped with a lower die wear-resistant plate through a third bolt, a through hole is opened in the lower anti-side block corresponding to the guide column position, and a guide sleeve is installed inside the through hole.

[0005] Preferably, a key slot is provided at a position of the upper anti-side block corresponding to the upper key block and a position of the lower anti-side block corresponding to the lower key block.

[0006] Preferably, the guide post is inserted into the guide sleeve.

[0007] Preferably, the upper die seat and the upper side-protection block are both provided with first bolt holes at positions corresponding to the first bolts.

[0008] Preferably, the upper mold wear-resistant plate and the lower mold wear-resistant plate are positioned correspondingly and fit together.

[0009] Preferably, the upper key block is installed in a T-shaped manner on the upper die seat at the top end of the upper anti-side block, and the lower key block is installed in a T-shaped manner on the lower die seat at the bottom end of the lower anti-side block.

[0010] Beneficial effects: When the utility model is used, the whole working process includes two stages:

[0011] The first stage: in the initial mold opening state, the upper mold base is at the upper dead center of the machine tool, the lower mold base is on the working table of the punch press, the lower mold base is stationary during the entire working process, the upper side block integral assembly is connected and fixed to the upper mold base with the guide column and rises to the upper dead center of the slider on the punch press, the lower side block integral assembly is connected and fixed to the lower mold base on the lower punch press table, this is the mold opening state.

[0012] The second stage: the movement starts. The upper die punch slider drives the upper die seat and its components to move downward. The guide column first contacts the lower die guide sleeve, and also serves as the first precise guide to ensure dimensional accuracy and avoid collision and interference between the components in the die. When the upper die guide column continues to move downward to 2 / 3 of the lower die guide sleeve, the upper die wear plate starts to work and rubs against each other to contact the lower die wear plate. This is the starting point of the lateral block contact, and the upper and lower wear plates contact 5MM. At this time, the lateral force in the mold is transmitted to the upper and lower side blocks, and the upper and lower side blocks start to work. The lateral forces transmitted in the mold offset each other and disperse to the side blocks on both sides of the mold. At this time, the stability of the workpiece and the forming state of the workpiece are guaranteed. The upper punch slider drives the upper die assembly to continue to descend until the mold is dead. At this time, the top of the upper die wear plate is as low as 10mm from the bottom of the lower die wear plate to achieve complete friction. At this time, the assembly is fully completed, the lateral force is completely offset, and the mold is accurately closed.

[0013] The utility model has a novel structure and ingenious conception, saves space, reduces processing difficulty, improves precision, reduces assembly difficulty, has precise guiding and accurate positioning, offsets lateral forces, ensures the stability of the workpiece by anti-side blocks, improves efficiency, improves the production quality of automobile parts, ensures the safety of personnel operation, and reduces development costs.
