Description

Technical Field

[0001] This utility model relates to the field of oil well tool mold manufacturing technology, and in particular to a high-pressure rubber plug mold with high processing efficiency. Background Technology

[0002] The production of extended high-pressure rubber stoppers nowadays is all done through the design of molds. The actual weighed rubber material and core skeleton are placed in the mold through the manufacturing process. The quality of the extended high-pressure rubber stopper products is ensured by controlling the pressure, vulcanization time, vulcanization temperature, mold venting, and excess material removal of the equipment.

[0003] Because this mold is made by combining upper and lower molds, when manufacturing the extended high-pressure rubber stopper, the core skeleton is first installed in the lower mold, and then the rubber material is placed in the core skeleton and mold in sequence. Then the upper mold is inserted, and the rubber material and core skeleton are pressed into shape in the mold using the pressure of a vulcanizing machine. The reason for this is that the upper and lower molds are pressed horizontally, which causes the rubber material in the upper and lower molds to be inconsistent when filling. Under the pressure of the vulcanizing machine, the core skeleton in the mold is skewed, the rubber material is unevenly distributed, and there are local defects, requiring multiple fillings. As a result, the core skeleton of the extended high-pressure rubber stopper is not concentric with the wings of the stopper, and the appearance of the stopper is also not aesthetically pleasing. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure rubber stopper mold with high processing efficiency, which has the effect of high processing efficiency of high-pressure rubber stopper mold.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-pressure rubber stopper mold with high processing efficiency, comprising a base and a mold, wherein the base is fixedly connected to the bottom of the mold, the mold has multiple segmented blocks respectively opened inside, the mold has a collar opened inside, the base has a core skeleton fixedly connected inside, the top of the mold has a top cover, and the base has lifting rods fixedly connected to both sides.

[0006] By adopting the above technical solution, and addressing the issues of insufficient filling of the high-pressure rubber stopper core skeleton by lengthening it, the previous horizontal upper and lower mold pressing method has been changed to a mold formed by multiple vertical segments and rings. First, the core skeleton is fixed to the bottom seat of the mold. Then, the weighed rubber material is filled sequentially from the bottom onto the segments and rings until the top cover is placed. The mold is then pressed under pressure using a vulcanizing machine, and excess rubber material is removed. Following the process requirements of pressure, vulcanization temperature, and vulcanization time in the vulcanizing machine, the rubber stopper is produced. Compared with existing technologies, this structure's lengthened high-pressure rubber stopper mold production method shortens the molding time by lengthening the high-pressure rubber stopper process and filling the rubber material. It also compensates for the unattractive appearance of the lengthened high-pressure rubber stopper. Through multiple production runs, the number of lengthened high-pressure rubber stoppers produced compared to the previous horizontal upper and lower mold pressing method has increased. Therefore, this structure can efficiently mold high-pressure rubber stoppers.

[0007] A further feature of this invention is that the plurality of segmented blocks are disposed on the inner side of the mold, and the plurality of segmented blocks are fin-shaped.

[0008] By adopting the above technical solution, multiple segmented blocks fill the mold, enabling the mold to be cast.

[0009] A further feature of this invention is that the number of lifting rods is four, and the four lifting rods are distributed in a circular array.

[0010] By adopting the above technical solution, four lifting rods are distributed around the outside of the base.

[0011] A further feature of this invention is that each of the four lifting rods has a lifting lug fixedly connected to its top, and a hook is attached to the inside of each lifting lug.

[0012] By adopting the above technical solution, the hook is attached to the inside of the lifting lug, so that the hook can be connected to the top of the lifting rod.

[0013] A further feature of this invention is that one end of the hook is fixedly connected to a chain, and the end of the chain is fixedly connected to a collecting belt.

[0014] By adopting the above technical solution, the chain is fixed to the end of the hook, and there are four hooks and four chains. The four hooks and chains are bundled together by a collection belt, so that the four hooks and chains can be bundled together and connected to the outside of the collection belt by a lifting device, thereby enabling the structure to be lifted.

[0015] A further feature of this invention is that the hook has an anti-detachment pin internally rotatably connected.

[0016] By adopting the above technical solution, the hook is designed to prevent it from falling off inside the lifting lug.

[0017] A further feature of this invention is that an anti-slip pad is fixedly connected to the bottom of the base, and anti-slip particles are fixedly connected to the bottom of the anti-slip pad.

[0018] By adopting the above technical solutions, the anti-slip mat and anti-slip particles increase friction and enhance the support stability of the base.

[0019] A further feature of this invention is that a sealing ring is fixedly connected to the inner side of the top cover.

[0020] By adopting the above technical solution, the sealing ring seals the gap between the top cover and the mold.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model, through the arrangement of the base, segmented blocks, collars, core skeleton, top cover, and mold, addresses the issue of insufficient filling of the extended high-pressure rubber stopper's core skeleton and the use of rubber material. It replaces the previous horizontal upper and lower mold pressing method with a mold formed by multiple vertical segmented blocks and collars. First, the core skeleton is fixed to the bottom of the mold. Then, weighed rubber material is sequentially filled from the bottom onto the segmented blocks and collars until the top cover is placed. The mold is then pressed using a vulcanizing machine, and excess rubber material is removed. Following the process requirements of pressure, vulcanization temperature, and vulcanization time in the vulcanizing machine, the rubber stopper is produced. Compared to existing technologies, this extended high-pressure rubber stopper mold manufacturing method shortens the molding time by lengthening the high-pressure rubber stopper and filling the rubber material. It also compensates for the unsightly appearance of the extended high-pressure rubber stopper. Through multiple production runs, the number of extended high-pressure rubber stoppers produced is increased compared to the previous horizontal upper and lower mold pressing method. Therefore, this structure can efficiently mold high-pressure rubber stoppers.

By lengthening the concentricity of the core skeleton of the high-pressure rubber stopper and addressing the issue of insufficient filling of the rubber material, the previous horizontal upper and lower mold pressing method has been changed to a mold formed by multiple vertical segmented blocks 2 and collars 3.

Compared with existing technologies, this structure's extended high-pressure rubber stopper mold manufacturing method shortens the molding time by lengthening the high-pressure rubber stopper process and filling the rubber material. It also compensates for the unsightly appearance of the extended high-pressure rubber stopper. Through multiple production runs, the number of extended high-pressure rubber stoppers produced by pressing with horizontal upper and lower molds is increased. Therefore, this structure can efficiently mold high-pressure rubber stoppers, producing multiple... Segmented blocks 2 are disposed inside the mold 11. Multiple segmented blocks 2 are fin-shaped and fill the mold 11, allowing the mold to be cast. There are four lifting rods 6, which are arranged in a circular array around the outside of the base 1. Each of the four lifting rods 6 has a lifting lug 7 fixedly connected to its top. A hook 8 is attached to the inside of the lifting lug 7. The hook 8 is attached to the inside of the lifting lug 7 so that it can be connected to the top of the lifting rod 6. A chain 9 is fixedly connected to one end of the hook 8. A collection belt 10 is fixedly connected to the end of the chain 9. The chain 9 is fixed to the end of the hook 8, and the hook 8 and the chain are connected together. There are four hooks 8 and four chains 9.

[0030] In this invention, by lengthening the concentric core skeleton of the high-pressure rubber stopper and addressing the issue of insufficient rubber filling, the previous horizontal upper and lower mold pressing method has been changed to a mold formed by multiple vertical segmented blocks 2 and collars 3. First, the core skeleton 4 is fixed to the bottom seat of the mold. Then, the weighed rubber material is sequentially filled from the bottom onto the segmented blocks 2 and collars 3 until the top cover 5 is placed on top.

Compared with existing technologies, this structure's extended high-pressure rubber stopper mold manufacturing method lengthens the high-pressure rubber stopper during the manufacturing process and reduces the amount of rubber material filled. The short casting time also compensates for the unsightly appearance of the extended high-pressure rubber plug. Through multiple productions, the number of extended high-pressure rubber plugs produced by pressing with horizontal upper and lower molds has increased. Therefore, this structure can efficiently cast high-pressure rubber plug molds. Four lifting rods 6 are distributed around the outside of the base 1.
