[0005] A groove is formed on the inner circle of the end surface of one axial side of each mold half. After the three mold halves are surrounded in a circular ring shape, the grooves of each mold half are surrounded to form a positioning cavity.

[0006] An insert is respectively arranged at the middle of the arc length direction of each mold half, and the insert radially extends to the inner side of the inner wall of the mold half.

[0007] As a further improvement of the utility model, a slot is provided on the mold halves, and the connecting end of the insert is clamped in the slot.

[0008] As a further improvement of the present invention, the thickness of the insert is 1.7 mm.

[0009] As a further improvement of the present invention, the diameter of the inner circle is 2 mm, and the radius of each mold half is 47±0.05 mm.

[0010] As a further improvement of the utility model, one end of the mold half is constructed as a wire cutting line, and a gap of 3 mm is provided between the outer circle and the inner circle at the other end of the mold half.

[0011] The technical effect of the utility model is that the mold in the traditional mold is concentric, and through the improvement and innovation of the mold structure, the product can be pre-compressed in the circumferential direction, and the mold adding and demoulding operations are smooth, fast and simple during mass production, and the performance of the product is more stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model.

[0013] Figure 2 It is a left view of the utility model. DETAILED DESCRIPTION

[0014] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0015] Figure 1 , 2 The mold comprises a mold half 1, a positioning cavity 2, an insert 3, a wire cutting line 4 and the like.

[0016] like Figure 1 , 2 As shown, the utility model is a rubber vulcanization mold for a rubber connecting rod, comprising three arc-shaped mold halves 1 of the same structure, the three mold halves 1 are connected end to end to form a circular ring, and the virtual inner circle at the center of the circular ring formed by the three mold halves 1 is located on the inner circle. In specific practice, the diameter of the inner circle is 2 mm.

[0017] A groove is constructed on the inner circle of the end surface on one axial side of each mold half 1. After the three mold halves 1 are gathered into a circular ring shape, the grooves of each mold half 1 are gathered together to form a positioning cavity 2.

[0018] An insert piece 3 is respectively arranged in the middle of the arc length direction of each mold half 1 , and the insert piece 3 radially extends to the inner side of the inner wall of the mold half 1 .

[0019] A slot is provided on the mold half 1, and the connecting end of the insert piece 3 is clamped in the slot.

[0020] The thickness of the insert 3 is 1.7 mm.

[0021] The radius of each mold half 1 is 47±0.05 mm.

[0022] One end of the mold half 1 is configured as a wire cutting line 4, and a gap of 3 mm is provided between the outer ring and the inner ring at the other end of the mold half 1. The utility model product adopts a structure of three mold halves 1 to achieve smooth and fast mold addition and demolding operations during mass production, and can ensure that the performance of the product is more stable and reliable.

[0023] In specific work, the outer diameter of the connecting rod ball joint product in the free state is φ96.5mm. In order to achieve the radial stiffness of the product, the product with an outer diameter of φ96.5 needs to be pressed into an inner tube of φ95mm. In the existing technology, if the mold in the rubber mold is a whole circle, it is impossible to achieve compression of the product in the circumferential direction. The rubber vulcanization mold of the utility model is designed to achieve compression of the product in the circumferential direction. The design radius of the rubber vulcanization mold of the rubber connecting rod of the utility model is the same as the size of the mold piece 1, but the center of the radius of the rubber vulcanization mold is not the center of the circle, but a small circle with a center design of φ2. Each mold piece 1 is evenly divided from the small circle of φ2 at 45 degrees, and a 1.7mm thick insert is designed in the middle part of the evenly divided mold piece 1. In this way, the product produced can meet the outer diameter size of φ96.5mm in the free state and the outer diameter size of φ95mm in the use state.
