Description

Technical Field

[0001] The utility model relates to the technical field of rubber extrusion dies, in particular to a shaping die used for automatic extrusion molding of vulcanized rubber. Background Art

[0002] When vulcanized rubber is subjected to repeated flexing, stress concentration can lead to cracks in certain areas of its surface. If a crack forms in this area, it will propagate perpendicular to the stress. While some soft vulcanized rubbers, particularly those made from styrene-butadiene rubber (SBR), exhibit significant resistance to initial cracking, cracks propagate rapidly once they form. Therefore, flexion testing is crucial for both crack initiation and crack growth resistance.

[0003] After searching, the existing patent (publication number: CN 214447928 U) discloses a shaping mold for vulcanized rubber extrusion molding, which relates to the technical field of rubber extrusion molds and solves the problem that excessive vulcanized rubber raw materials cannot overflow, resulting in inconsistent thickness in subsequent extrusion molding. It includes an upper mold fixture and a lower mold fixture for extruding vulcanized rubber. The lower mold fixture includes a shaping module, and a shaping groove for accommodating vulcanized rubber is opened on the shaping module. The shaping module also has an overflow groove connected to the shaping groove. When the upper mold fixture and the lower mold fixture are pressed together, the excess vulcanized rubber raw materials in the shaping groove can flow into the overflow groove for storage, and then the thickness of the formed experimental sample after being taken out and cooled remains the same.

[0004] However, in the above solution, after the rubber product is injection molded by the mold, the staff needs to manually tear off the finished product. However, manual tearing not only easily damages the finished product, but also has certain risks and reduces work efficiency.

[0029] In this embodiment, the ejecting mechanism 3 includes a connecting plate 31, a disc 32, a transmission column 33, a lifting plate 34, a limiting rod 35, a transmission plate 36 and a top plate 37. The bottom of the lower mold 2 is fixedly connected to the connecting plate 31, the side of the connecting plate 31 is rotatably connected to the disc 32, the side of the disc 32 is fixedly connected to the transmission column 33, the surface of the transmission column 33 is fitted with the lifting plate 34, the side of the lifting plate 34 is fixedly connected to the limiting rod 35, the other side of the lifting plate 34 is fixedly connected to the transmission plate 36, and the top of the transmission plate 36 is fixedly connected to the top plate 37. By setting up the ejecting mechanism 3, the purpose of automatic ejecting can be achieved, and the problem of damage to the workpiece caused by manual pulling of the workpiece by the staff can be prevented, thereby further improving work efficiency and ensuring the safety of the staff from a certain perspective.

[0030] In this embodiment, two groups of connecting tubes 7 are provided on the top of the upper mold 6. The upper mold 6 is slidably connected to the four groups of brackets of the mounting frame 4. The electric telescopic rod 5 is controlled by the controller body 9, so that the electric telescopic rod 5 drives the upper mold 6 to slide downward along the surface of the four groups of brackets of the mounting frame 4. At this time, the four groups of brackets of the mounting frame 4 will have a certain limiting effect on the upper mold 6.

[0031] In this embodiment, a groove matching the protective plate 10 is provided on the top of the control device body 8, and two groups of round holes matching the push rods 11 are provided on the inner wall of the control device body 8. The protective plate 10 is pulled upward by the push rods 11 so that the protective plate 10 slides upward along the inner wall of the groove of the control device body 8. When the controller body 9 is exposed, the push rod 11 can be pushed backward so that the push rod 11 is embedded in the round hole on the upper inner wall of the control device body 8, and the protective plate 10 can be fixed in the current position. At this time, the controller body 9 can be used. When it is not needed, the push rod 11 can be pulled out and the protective plate 10 can be pulled downward by the push rod 11 so that the protective plate 10 slides downward along the inner wall of the groove of the control device body 8.

Because the transmission column 33 is fixedly connected to the disc 32 and the transmission column 33 passes through the transverse groove on the side of the lifting plate 34, when the disc 32 rotates, it will drive the transmission column 33 to rotate and at the same time slide forward inside the transverse groove of the lifting plate 34. At this time, the transmission column 33 will apply a pulling force to the lifting plate 34, causing the lifting plate 34 to move upward.

The two groups of limit rods 35 are respectively embedded in the two groups of vertical grooves on the side of the connecting plate 31 and are slidably connected to the connecting plate 31. Because the two groups of limit rods 35 are fixedly connected to the lifting plate 34, when the lifting plate 34 moves, it will drive the two groups of limit rods 35 to slide upward in the two groups of vertical grooves on the side of the connecting plate 31, and have a certain limiting effect on the lifting plate 34, so that the lifting plate 34 rises vertically. At this time, the two groups of transmission plates 36 fixedly connected to the lifting plate 34 will rise vertically accordingly.

[0034] In this embodiment, two groups of rectangular grooves matching the top plates 37 are provided at the bottom of the lower mold 2. The two groups of top plates 37 are respectively embedded in the two groups of rectangular grooves at the bottom of the lower mold 2 and are slidably connected to the lower mold 2. Because the two groups of top plates 37 are respectively fixedly connected to the two groups of transmission plates 36, when the two groups of transmission plates 36 rise, they will drive the two groups of top plates 37 to slide upward along the inner walls of the two groups of rectangular grooves at the bottom of the lower mold 2 and eject the workpiece, thereby achieving the purpose of automatic ejection.

[0036] In this embodiment, four groups of pillars 13 and shock-absorbing bases 14 are provided, and the tops of the four groups of shock-absorbing bases 14 are provided with grooves matching the pillars 13. The four groups of pillars 13 at the bottom of the extrusion equipment body 1 are respectively embedded in the grooves at the tops of the four groups of shock-absorbing bases 14, and the extrusion equipment body 1 can be installed above the shock-absorbing bases 14.

[0037] In this embodiment, four groups of shock-absorbing device bodies 15 are arranged inside each group of shock-absorbing bases 14. The shock-absorbing device bodies 15 are spring shock absorbers. Because four groups of shock-absorbing device bodies 15 are arranged inside each group of shock-absorbing bases 14, when the extrusion device body 1 is working, the shock-absorbing base 14 will play a certain role in reducing shaking through the shock-absorbing device bodies 15, thereby enhancing the stability of the extrusion device body 1.

[0038] After the mould 10 is in the working state, the upper mould 10 is moved along the groove of the mould 10 and the lower mould 10 is moved along the groove of the mould 10. After the mould 10 is in the working state, the upper mould 10 is moved along the groove of the mould 10. After the mould 10 is in the working state, the upper mould 10 is moved along the groove of the mould 10. After the mould 10 is in the working state, the upper mould 10 is moved along the groove of the mould 10. When the lifting plate 34 is lifted up, the lifting plate 34 is lifted up, and the lifting plate 34 is lifted up.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
