They typically have properties such as shock absorption, vibration isolation, high temperature resistance, and corrosion resistance to ensure the stability and accuracy of the equipment during operation. In their production process, compression molding is used to mold the bearing pads, and the steel and rubber are molded together through the mold.

[0003] Chinese utility model patent CN217990620U discloses a stamping die, which includes "a lower die and an upper die, the lower die being used to support the workpiece to be formed, including a lower die base and a first fixed plate, the first fixed plate being fixedly installed on the lower die base, a die cavity being installed on the first fixed plate, the die cavity having multiple stamping holes, and a positioning component being provided on the die cavity, the positioning component being used to position the workpiece to be formed; the upper die and the lower die being spaced apart in the vertical direction, including an upper die base, multiple punches, and a stripper plate, the multiple punches and the stripper plate being installed on the lower side of the upper die base, the punches being set corresponding to the die cavity, and being set through the stripper plate"; however, it was found during the use of this die that the workpiece needs to be manually removed after compression molding, and workers use tools to pry the workpiece out, which easily damages the surface of the workpiece, and generates a large impact force during the compression molding process. If the upper die and the lower die are tightly fitted, it is easy for the gas during compression molding to be difficult to escape, thus affecting the compression molding effect of the workpiece. Utility Model Content

[0004] The purpose of this invention is to provide a precision equipment bearing pad compression mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision equipment bearing pad compression mold, including a lower mold fixing plate, a lower template provided on the top surface of the lower mold fixing plate, foot molds respectively provided on the top surfaces of the lower template on both sides, a top plate and a fixed bottom plate provided on the top surface of the lower template, an ejector guide post movably sleeved on the inner wall of the top plate and the fixed bottom plate, the outer wall of the ejector guide post movably sleeved on the inner wall of the die, the top surfaces of the foot molds on both sides of the die, one of the foot molds is fixedly connected to an upper guide post, the outer wall of the upper guide post movably sleeved on the inner wall of the die;

[0042] A parting surface gap 19 is left between the bottom surface of the lower template 2 and the top surface of the cavity mold 7;

[0043] The top plate 4 and the fixed bottom plate 5 are connected by fixing bolts 320.

[0044] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the ejector guide post 6 is located on the top surface of the lower template 2.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the interior of the die 7 is provided with a first column hole 71 and a second column hole 72.

[0047] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the top surface of the ejector rod 15 is spherical.

[0048] This precision equipment supports the compression mold, and its working process is as follows:

[0049] First, the lower mold fixing plate 1 is firmly installed on the workbench with fasteners. Then, fixing bolts 17 are used to pass through the corresponding screw holes 16 of the lower mold fixing plate 1, lower template 2, foot mold 3 and die 7 in sequence, and these components are tightly connected into an integral structure. At this time, the die 7 is connected to the ejector guide post 6 and the upper guide post 8 through its column hole 71 and column hole 72 respectively.

Finally, the punch template 12 is passed through the limiting groove 91 of the punch fixing plate 9, and fixing bolts 10 are used to assemble and fix the punch fixing plate 9 and the upper template 11.

[0050] During the molding process, the operator first places the steel parts and rubber materials into the cavity 73 of the die 7 in sequence. Then, the top of the upper guide post 8 is inserted into the post hole 92 of the punch fixing plate 9, so that the punch plate 12 enters the cavity 73 smoothly for compression molding. During the compression molding process, the temperature of the mold can be controlled through the heating hole 74. The designed ejector guide post 6 and the upper guide post 8 form a parting surface gap 19 between the lower mold fixing plate 1 and the die 7. Combined with the overflow flash structure at the top of the cavity 73, it ensures smooth venting during the compression molding process. The deepened cavity 73 structure ensures that the punch plate 12 can apply sufficient molding pressure, which significantly improves the product qualification rate.

[0051] After molding, the pneumatic system provides compressed air to the pneumatic cylinder 14, driving the ejector rod 15 to rise smoothly from the rod hole 18. The spherical ejector end design increases the contact area with the workpiece, ensuring a smooth and impact-free ejection process, effectively avoiding damage to the product surface, and achieving excellent ejection results.
