Description

Technical field:

[0001] The utility model relates to the technical field related to wheel hubs, and more specifically to a wheel hub mold device without a side mold oil cylinder. Background technology:

[0002] According to the existing wheel hub mold structure principle, the lower mold is mainly a fixed mold, and the upper mold is a movable mold, which can be moved up and down by a cylinder. In addition, there are 4 side molds, each of which is moved in and out by a cylinder; thus realizing the opening and closing process of the wheel hub mold.

[0003] All side molds need to be driven by a separate oil cylinder, which has a complex structure and high cost. In addition, the pushing distance and running time of the push rod of each oil cylinder need to be kept as the same as possible, and the initial installation and adjustment are troublesome. Utility model content:

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a wheel hub mold device without a side mold oil cylinder. Its side molds do not need to be pushed by the oil cylinder. It only needs to lower the upper mold plate to bring the upper mold and four side molds together and close the mold with the bottom mold. It has a simple structure, is easy to install and has a good use effect.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A wheel hub mold device without a side mold oil cylinder comprises an upper mold connection plate and a bottom mold plate, wherein the upper mold connection plate is located directly above the bottom mold plate, a bottom mold is fixed to the middle of the top surface of the bottom mold plate, an upper mold plate is installed below the upper mold connection plate, side mold guide seats are fixed to the front and rear bottom surfaces of the left and right sides of the upper mold plate, a movable through groove is formed between two adjacent side mold guide seats, a corresponding side mold is located between the corresponding two adjacent side mold guide seats, and the side mold moves laterally along the movable through groove;

[0007] At least one guide rod extending obliquely outward and upward is fixed on the bottom mold plate just below the side mold, and the guide rod is inserted into an oblique through hole formed on the corresponding side mold.

[0008] Laterally extending guide grooves are formed on the side walls of the side mold guide seats on both sides of the movable groove, and side guide strips are installed on the side walls of the side mold facing the side mold guide seats. The side guide strips are inserted into the corresponding guide grooves and cooperate with the guide grooves.

[0009] This structure allows the side molds to move laterally when they descend along the guide rods, so that all the side molds are brought closer together.

[0010] An upper mold is fixed on the middle bottom surface of the upper mold plate, and the upper mold corresponds to the bottom mold up and down.

[0011] The bottom surface of the side mold is pressed against the top surface of the bottom mold plate.

[0012] A side mold locking ring is fixed on the top surface of the bottom mold plate at the outer side of the side mold, and the inner wall of the side mold locking ring is a conical wall with a large diameter at the upper end and a small diameter at the lower end. The outer wall of the side mold is close to the inner wall of the side mold locking ring.

[0013] The outstanding effects of the utility model are:

[0014] Its side molds do not need to be pushed by oil cylinders. It only needs to lower the upper mold plate to bring the upper mold and four side molds together and close the mold with the bottom mold. It has a simple structure, is easy to install, and has a good use effect. Description of the drawings:

It is an existing conventional structure and will not be described in detail here.

[0020] Further, the front and rear bottom surfaces of the left and right sides of the upper mold plate 30 are fixed with side mold guide seats 40, that is, four side mold guide seats 40 are fixed, and a movable through groove is formed between each two adjacent side mold guide seats 40, and the corresponding side mold 2 is located between the corresponding two adjacent side mold guide seats 40, and the side mold 2 moves laterally along the movable through groove; that is, a side mold 2 is installed at each of the four movable through grooves;

[0021] Two guide rods 50 arranged side by side and extending obliquely outward and upward are fixed on the bottom mold plate 20 directly below the side mold 2 . The guide rods 50 are inserted into oblique through holes formed on the corresponding side mold 2 .

[0022] Furthermore, laterally extending guide grooves 41 are formed on the side walls of the side mold guide seats 40 on both sides of the movable groove, and side guide strips 3 are installed on the side walls of the side mold 2 facing the side mold guide seat 40. The side guide strips 3 are inserted into the corresponding guide grooves 41 and cooperate with the guide grooves 41. A transverse mounting groove is formed on the side wall of the side mold 2 facing the side mold guide seat 40, and part of the side guide strips 3 are inserted into the transverse mounting groove. The side guide strips 3 are fixedly connected to the side mold 2 by bolts or part of the side guide strips 3 are clamped in the transverse mounting groove, that is, the side guide strips 3 are fixedly connected to the corresponding side mold 2.

[0023] A side wall of the side mold 2 facing the side wall of the side mold guide seat 40 is close to the corresponding side wall of the side mold guide seat 40 .

[0024] Furthermore, an upper mold 4 is fixed to the middle bottom surface of the upper mold 30 , and the upper mold 4 corresponds to the bottom mold 1 up and down. A central through hole is formed in the middle of the upper mold 30 , and the central through hole faces the middle of the upper mold 4 .

[0025] Furthermore, the bottom surface of the side mold 2 is pressed against the top surface of the bottom mold plate 20.

[0026] Furthermore, a side mold locking ring body 60 is fixed on the top surface of the bottom mold plate 20 at the outer side of the side mold 2, and the inner side wall of the side mold locking ring body 60 is a conical wall surface with a large diameter at the upper end and a small diameter at the lower end, and the outer side wall of the side mold 2 is close to the inner side wall of the side mold locking ring body 60;

[0028] Furthermore, the opposite end wall surfaces of the inner side walls of two adjacent side molds 2 are close to each other.

[0029] When this embodiment is in use, the upper mold connecting plate 10 is lowered, so that the upper mold plate 30 is lowered, and the upper mold 4 is lowered. At the same time, the guide rod 50 is inserted into the oblique through hole formed on the corresponding side mold 2. As the side mold 2 descends, it will move laterally along the guide rod 50, so that all the side molds 2 are brought together, until finally, the bottom surface of the side mold 2 is pressed against the top surface of the bottom mold plate 20, and the opposite end wall surfaces of the inner side walls of two adjacent side molds 2 in the four side molds 2 are close to each other, so that the inner walls of the four side molds 2 form an integral annular extended inner wall surface, and the edge of the upper mold 4 is inserted into the inner annular groove formed on the top surface of the inner side of the four side molds 2, and the bottom surface of the edge of the upper mold 4 is pressed against the bottom surface of the inner annular groove, so that the mold is closed and the casting process can be carried out.
