Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, in particular to a high-efficiency rubber production mold. Background Art

[0002] Natural rubber comes from the latex of plants such as rubber trees and rubber grass, and is obtained through processes such as coagulation and drying during processing. Rubber products are the activities of producing various rubber products using rubber (natural or synthetic) as raw materials. The manufacture of rubber products requires multiple processes, including batching, plasticizing, mixing, calendering, cutting, molding and vulcanization, etc. During molding, injection molds are required for processing and molding.

[0003] After searching the existing rubber product injection molding separation and demolding devices, it was found that the ejection mechanism is usually used for demolding. For example, application No. 202220804089.7 discloses a highly safe rubber product demolding machine. The telescopic cylinder is extended to enable the driving assembly to drive the bidirectional screw to rotate, and the bidirectional screw drive drives the two sets of moving blocks to move toward each other. The moving blocks drive the demolding assembly to eject the rubber product in the lower mold. However, this demolding method has too small a contact area at the vertex, which makes the pressure too high, which may cause deformation of the injection molded parts that have not been fully cooled, affecting the yield of the injection molded parts, reducing work efficiency, and is not conducive to people's use.

[0004] Therefore, the applicant proposes a highly efficient rubber production mold to solve the problem. Utility Model Content

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Depend on Figure 1-Figure 7 The utility model includes a mold table 1, a mold chamber 2 is provided on the top of the mold table 1, a lifting plate 4 is installed on the top of the mold chamber 2 through a lifting rod 3, an upper mold plate 5 is installed on the bottom of the lifting plate 4, and lower mold assemblies 6 are connected to the two sides of the lifting plate 4. The lower mold assembly 6 includes a slider 61 connected to the inner slide of the mold chamber 2, a driving rod 62 is hinged at the bottom of the slider 61, and the other end of the driving rod 62 is hinged to the side wall of the spliced ​​lower mold 63, and a sliding sleeve 64 is fixed on the front and back sides of the spliced ​​lower mold 63, and the sliding sleeve 64 slides outside the cross bar 65 fixed on the inner wall of the mold chamber 2.

[0026] As described above, when injection molding is carried out, the lifting rod 3 on the mold chamber 2 is started, and the lifting plate 4 drives the upper template 5 to move downward. At the same time, the slider 61 is driven to slide down, so that the driving rod 62 rotates and pushes the spliced ​​lower mold 63. The two spliced ​​lower molds 63 slide on the outside of the cross bar 65 through the sliding sleeve 64 for displacement. After that, the two spliced ​​lower molds 63 are first tightly spliced ​​together, and then the upper template 5 is close to the top of the spliced ​​lower mold 63 for injection molding. After the injection molding is completed, it is reset, and the two spliced ​​lower molds 63 are separated to allow the workpiece to automatically fall off for collection. In this way, manual demolding is not required, which effectively improves work efficiency and avoids possible damage to the workpiece caused by ejection. It is very practical.

[0027] The front and back sides of the spliced ​​lower mold 63 are welded with a bonding plate 66, which is fixed on the top surface of the sliding sleeve 64 and fixed with bolts. The sliding sleeve 64 and the inner wall of the mold chamber 2 are connected with a buffer spring 610, and the buffer spring 610 is sleeved on the outside of the cross bar 65. An elastic sliding rod 67 is slidably inserted through the bottom of the slider 61, and a connecting plate 68 is fixed to the bottom of the elastic sliding rod 67. The connecting plate 68 is hinged to the top of the driving rod 62, and the top of the connecting plate 68 is connected to the slider 61 with an extrusion spring 69 wrapped around the outside of the elastic sliding rod 67.

[0028] As mentioned above, in the optimized design of the lower mold assembly 6, when the two spliced ​​lower molds 63 are tightly spliced ​​together, the upper mold 5 is close to the top surface of the two spliced ​​lower molds 63. As the lifting plate 4 continues to move downward, the connecting plate 68 is fixed in position, so that the elastic slide bar 67 slides into the slider 61 and compresses the extrusion spring 69, so that it is convenient for the spliced ​​lower molds 63 to contact first, and then the upper mold 5 presses the spliced ​​lower mold 63, and the buffer spring 610 can play a buffering role. Finally, the bonding plate 66 facilitates the disassembly and cleaning of the spliced ​​lower mold 63.

[0029] A cooling fan 9 is installed on the inner wall of the mold chamber 2, and the cooling fan 9 blows air in the direction of the spliced ​​lower mold 63. A collecting box 7 is placed in the top groove of the mold table 1, and a rubber pad 71 is bonded to the inner wall of the collecting box 7. A positioning assembly 8 is provided on both sides of the collecting box 7 at the top of the mold table 1. The positioning assembly 8 includes a vertical plate 81 fixed to the top of the mold table 1, and a screw 82 is threadedly connected to the vertical plate 81, and a pressure plate 83 is fixed to one side of the screw 82.

[0030] As mentioned above, the cold fan 9 can be started during cooling to speed up the cooling effect, and the collection box 7 can collect the fallen workpieces. At the same time, the rubber pad 71 has high elasticity to prevent the workpieces from being broken. Finally, the screw 82 on the vertical plate 81 can be twisted so that the pressure plate 83 fixes the position of the collection box 7. Finally, after the workpiece falls, the collection box 7 can be pulled out to complete an injection molding job.

[0031] Working principle: During injection molding, the lifting rod 3 on the mold chamber 2 is started, and the lifting plate 4 drives the upper mold plate 5 to move downward. At the same time, the slider 61 is driven to slide down, so that the driving rod 62 rotates and pushes the spliced ​​lower mold 63. The two spliced ​​lower molds 63 slide on the outside of the cross bar 65 through the sliding sleeve 64 for displacement. Then, the two spliced ​​lower molds 63 are first tightly spliced ​​together, and then the upper mold plate 5 is close to the top of the spliced ​​lower mold 63 for injection molding. After the injection molding is completed, it is reset. The two spliced ​​lower molds 63 are separated to make the workpiece fall automatically, and the collection box 7 can collect the fallen workpiece. At the same time, the rubber pad 71 has high elasticity to prevent the workpiece from being damaged. After the workpiece falls, the collection box 7 is pulled out to complete an injection molding work. It should be noted that the injection tube of the upper mold plate 5 is a telescopic design, which is a prior art means.
