Description

Technical Field

[0001] The utility model relates to the technical field of die casting of automobile parts, and particularly relates to a die casting device for an automobile transmission housing. Background Technique

[0002] Die casting is a metal forming and processing method, usually used to manufacture high-precision, high-strength parts or components with complex shapes. Common die casting materials include aluminum alloy, zinc alloy, and magnesium alloy, etc. The die casting process is divided into multiple steps such as mold making, raw material melting, casting, demoulding, cleaning, and treatment. Die casting processing has the advantages of high production efficiency, long mold life, high production precision, reliable product quality, and low cost, and is widely used in industries such as automobiles, airplanes, heat engines, and electronics.

[0003] In the prior art, the usage environment of the die used in die casting is generally relatively harsh, and the integrity of the die itself needs to be checked frequently to avoid product defects caused by die problems. Existing die casting dies are extremely heavy, and for their inspection, operators generally need to check around them. To facilitate the inspection by operators, we have proposed a die casting device for an automobile transmission housing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a die casting device for an automobile transmission housing to solve the problems existing in the prior art proposed in the above background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A die casting device for an automobile transmission housing includes a base. Above the base, there is a mold body. A central groove is penetrated through the upper end of the base. The central groove is connected to the lower end of the mold body through a rotating mechanism. A positioning device is penetrated through the upper end of the base, and a limiting device is penetrated through the side wall of the base at the corresponding position.

[0007] Preferably, the rotating mechanism includes a rotating column rotatably connected to the inner wall of the central groove. At the upper end of the rotating column, there is a connecting plate fixedly connected. A connecting groove is penetrated through the lower end of the mold body at the corresponding position, and the connecting plate is fixedly connected in the connecting groove.

[0008] Preferably, the positioning device includes an annular groove penetrated through the upper end of the base. At the lower end of the mold body at the corresponding position, there are two positioning columns fixedly connected with opposite positions, and the positions of both positioning columns correspond to the position of the annular groove.

[0009] Preferably, the limiting device includes a threaded groove penetrating through the side wall of the base. A regulating screw is threadedly connected in the threaded groove. The threaded groove penetrates through the inner wall of the central groove. A limiting groove is penetratingly provided at the side wall of the rotating column at the corresponding position. The tail end of the regulating screw is located in the limiting groove.

[0010] Preferably, when the two positioning columns are located in the annular groove, the lower ends of the two positioning columns are both abutted against the inner bottom of the annular groove.

[0011] Preferably, the regulating screw penetrates through the annular groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, by arranging the rotating mechanism, the positioning device and the limiting device to cooperate with each other, a base is provided below the mold body. The base and the mold body are in a rotating connection relationship. When it is necessary to inspect the damage of the mold body, the regulating screw on one side can be screwed out, so that the rotating column can drive the mold body to rotate normally, which is convenient for the operator to inspect on the spot. When the mold body is put into normal use, the mold body and the base are in a relatively fixed relationship and will not be affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Refer to Figures 1-3, a die-casting device for automobile transmission housing, comprising a base 1, a mold body 2 is arranged above the base 1, a center groove is penetrated at the upper end of the base 1, the center groove and the lower end of the mold body 2 are connected by a rotating mechanism, the rotating mechanism comprises a rotating column 6 rotatably connected to the inner wall of the center groove, a connecting plate 5 is fixedly connected to the upper end of the rotating column 6, a connecting groove 7 is penetrated at the lower end of the mold body 2 at the corresponding position, and the connecting plate 5 is fixedly connected in the connecting groove 7.

[0020] Wherein, a positioning device is provided at the upper end of the base 1, and the positioning device includes an annular groove 4 provided at the upper end of the base 1, and two corresponding positioning columns 8 are fixedly connected at the lower end of the mold body 2 at the corresponding position, and the positions of the two positioning columns 8 correspond to the positions of the annular groove 4. A limiting device is provided at the side wall of the base 1 at the corresponding position, and the limiting device includes a threaded groove provided on the side wall of the base 1, and an adjusting screw 3 is threadedly connected in the threaded groove, and the threaded groove extends through the inner wall of the center groove, and a limiting groove is provided at the side wall of the rotating column 6 at the corresponding position, and the tail end of the adjusting screw 3 is located in the limiting groove.

[0021] It is worth mentioning that when the two positioning columns 8 are located in the annular groove 4, the lower ends of the two positioning columns 8 are against the inner bottom of the annular groove 4, and the positioning columns 8 also play a supporting role, which can avoid the collapse caused by uneven force. The adjusting screw 3 passes through the annular groove 4, and the adjusting screw 3 can limit the corresponding positioning column 8 through the annular groove 4 to prevent the mold body 2 from rotating when it is positioned and fixed.

[0022] In the present invention, when the mold body 2 needs to be inspected for damage, the operator can rotate the adjustment screw 3 on one side to disengage the tail end of the mold body 2 from the corresponding limit groove on the side wall of the rotating column 6, and continue to rotate it to completely disengage the annular groove 4, and then directly rotate the mold body 2, which is convenient for the operator to inspect the mold body 2 for damage on the spot, and directly reset it when it needs to be put into use, which will not affect the normal use of the mold body 2.

[0023] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model can make equivalent replacements or changes based on the technical solution and utility model concept of the utility model, which should be covered by the protection scope of the utility model.
