Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile production, and particularly relates to a die-casting mold steel for an automobile bracket. Background Technique
[0002] Automobile brackets need to be manufactured by die-casting molds. A die-casting mold is a tool for casting metal parts, a tool for completing the die-casting process on a special die-casting forging machine. The basic die-casting process is as follows: the molten metal is first cast into the cavity of the mold at a low speed or a high speed. The mold has a movable cavity surface, which is pressurized and forged during the cooling process of the molten metal, eliminating the shrinkage cavity and porosity defects of the blank, and also making the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blank are significantly improved.
[0003] Since the die-casting mold is in a high-pressure working state for a long time, it is easy to produce small deviations after being used for a period of time. The conventional die-casting mold lacks a coordination mechanism, resulting in the problem that the conventional die-casting mold is difficult to fine-tune and reset.
[0004] Therefore, we propose a die-casting mold steel for an automobile bracket to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem that the conventional die-casting mold is difficult to fine-tune and reset, and to propose a die-casting mold steel for an automobile bracket.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A die-casting mold steel for an automobile bracket, including a mold body. The lower end of the mold body is uniformly and fixedly connected with pistons. An oil cylinder is movably and hermetically installed outside the pistons. An oil guide pipe is connected between the oil cylinders. The lower end of the oil cylinder is fixedly connected with a base. A threaded rod is fixedly connected to the outside of the base. A scale is slidably installed on the threaded rod. A threaded sleeve is threadedly installed on the outside of the threaded rod. The scale is in movable contact with the mold body. Loosen the threaded sleeve, then calibrate the scale, and then tighten the threaded sleeve to fix the scale tightly by using the threaded sleeve, which is convenient for correcting the scale.
[0008] Inject oil into the oil cylinder through the oil guide pipe, so that the oil acts on the piston, the piston acts upward on the mold body, and the mold body rises upward. Observe the rising amplitude with reference to the scale until the mold body reaches the target scale and stop injecting oil, which is convenient for correcting again after the mold body is displaced.
[0009] Preferably, an oil valve is installed on the oil guide pipe. After adjusting the height of the mold body, close the oil valve to shield the oil between the oil cylinders by using the oil valve, which is convenient for preventing the oil pressure from being conducted.
[0010] Preferably, a marking block is fixedly connected to the outside of the mold body, and the marking block is in movable contact with the scale. The relative position between the mold body and the scale can be conveniently observed through the scale.
[0011] Preferably, the threaded rod includes a threaded rod body, and an anti-rotation surface is provided on the side of the threaded rod body. The anti-rotation surface is used to guide the lifting of the scale and prevent the scale from rotating at the same time, improving the stability of the scale angle.
[0012] Preferably, the threaded sleeve includes a nut and a pressing ring, and the pressing ring is fixedly connected to the outside of the nut. By using a wrench to screw the nut, the nut drives the pressing ring to tightly press and fix on the scale, which is convenient for locking or unlocking the scale.
[0013] Preferably, the scale includes a scale body, and a sliding groove is provided at the lower part of the scale body.
[0014] Preferably, standard scales are provided at the upper part of the scale body. It is convenient to observe whether the marking block is in place through the standard scales.
[0015] In summary, the technical effects and advantages of the present utility model are as follows:
[0016] 1. Loosen the threaded sleeve, then calibrate the scale, and then tighten the threaded sleeve. Use the threaded sleeve to tightly press and fix the scale, which is convenient for correcting the scale.
[0017] 2. Inject oil into the oil cylinder from the oil guide pipe, make the oil act on the piston, make the piston act upward on the mold body, make the mold body rise upward, and observe the rising amplitude with reference to the scale until the mold body reaches the target scale and stop injecting oil, which is convenient for correcting again after the mold body is displaced.
[0018] 3. After adjusting the height of the mold body, close the oil valve, and use the oil valve to shield the oil between the oil cylinders, which is convenient for preventing oil pressure conduction. BRIEF DESCRIPTION OF THE DRAWINGS
