Example 1

As shown in fig. 1, an embodiment of the present invention is presented.

The embodiment provides a production process of a silica gel barrel, which at least comprises the following steps:

s1, preparation stage: preparing a silica gel raw material and a vulcanizing agent in advance, uniformly mixing, and then carrying out rubber mixing by using rubber mixing equipment to form a mixed rubber material; when the method is specifically implemented, the silica gel raw material and the vulcanizing agent are prepared according to actual conditions, and the silica gel raw material is subjected to the steps of screening, impurity removal, cleaning, drying and the like, so that the silica gel raw material has higher purity. There are many vulcanizing agents on the market, and there are many manufacturers, and the specific type of the vulcanizing agent is not limited herein, as long as the vulcanizing agent can be matched with the silica gel raw material to realize a high-temperature vulcanizing process at a later stage. In the mixing process, stirring equipment can be used for mixing, the mixing effect is improved, and after uniform mixing, the mixture is fed into rubber mixing equipment for rubber mixing operation to form a mixed rubber material in a molten state.

S2, color matching stage: selecting corresponding color paste, mixing the color paste into a mixed rubber material, continuously mixing by using rubber mixing equipment, uniformly mixing to obtain a finished product mixture, and waiting for later use; in actual use, the corresponding color paste is selected according to the desired color, the mixed rubber material in the rubber mixing state is directly mixed into the color paste, stirring and rubber mixing are carried out again until the color is uniformly mixed, and a finished mixed material is formed and is ready for use.

S3, manufacturing a die: according to production requirements, carrying out corresponding parameter setting on split molding equipment, and after the setting is finished, carrying out die opening by using the die opening equipment to finish the manufacture of the barrel die to form a finished product die; according to the embodiment, according to actual conditions, various parameters of the silica gel barrel to be produced are converted into manufacturing parameters of the mold, the manufacturing parameters are input into mold opening equipment, accurate mold opening is achieved, the precision is high, and after the mold opening is completed, the finished mold of the silica gel barrel can be obtained.

S4, mold treatment: placing the finished product mold manufactured in the step S3 on an oil press, and preheating the finished product mold by using the oil press; preheating the finished product mould, can reducing the start-up process of later stage vulcanization, the temperature has directly reached vulcanization temperature, needn't wait for the slow heat gain of earlier stage, improves shaping and vulcanization efficiency.

S5, product molding: and after preheating, placing the finished product mixed material into a finished product mold, heating the finished product mold by an upper mold and a lower mold separately until the temperature reaches different temperatures, lasting for 90-100 min, then carrying out compression molding, stopping heating after the compression molding time is reached, cooling, and finally demolding to obtain a finished product for later use. When the finished product mixed material in the finished product mold is heated, the upper mold and the lower mold adopt different heating and shaping temperatures, so that the purpose that the opening and the body of the same product silica gel barrel have different properties is realized, and the actual production requirement is met. The heating time lasts at least 90min, and stable shaping is realized. In the heating and shaping process, the die is further shaped by performing die pressing operation on the barrel blank, and the formed barrel blank is compacted and shaped by the die pressing operation to form a final silica gel barrel finished product, so that the shaping effect is improved.

In this embodiment, the method further includes the following steps:

And finally, carrying out final fine treatment on the finished product of the silica gel barrel, such as edge trimming, burr treatment and the like, sending the finished product to a quality part for inspection and control, and packaging the finished product after the finished product is qualified.

In this example, the weight ratio of the silica gel raw material to the vulcanizing agent was 48:1 to 52: 1. Through a large number of experiments and verifications, when the weight ratio of the silica gel raw material to the vulcanizing agent is within the range of 48:1-52:1, the finished product prepared is high in yield and good in quality; in this example, each 2kg of silica gel raw material was mixed with 50g of vulcanizing agent, i.e. the weight ratio of the two was 50: 1.

In this embodiment, the rubber mixing device is a rubber mixing mill, and the rubber mixing mill is an internal rubber mixing mill. The rubber mixing machine is used as necessary equipment in rubber mixing, and can well realize the realization of a mixture of a vulcanizing agent and a silica gel raw material in a melting table; the closed rubber mixing mill is mainly used for plasticating and mixing rubber relative to the open rubber mixing mill, and has one more mixing chamber than the open rubber mixing mill. Since the invention of elliptical rotor internal mixers in 1916, internal mixers have been rapidly developed in the rubber industry, and other types of rotors have appeared later. The maximum capacity of the mixing chamber of a modern internal rubber mixer is up to 650 liters. Is very suitable for mixing the silica gel raw material and the vulcanizing agent.

In this example, the kneading was continued in S2 for a kneading time of 20 to 30 min. Also, after a lot of experiments, it is best that the mixing time is 20 minutes to 30 minutes to achieve the mixing effect. Compared with the mixing of relative rubber, the silica gel mixing time needs more, and the better silica gel mixing effect is realized.

In this embodiment, the mold opening device is a CNC numerical control device, and the CNC numerical control device is a PLC programmable numerical control device. Utilize PLC programmable numerical control equipment to carry out accurate die sinking for the precision of finished product mould is higher, also is favorable to the finished product precision height of later stage silica gel bucket. And because the parameters of the die sinking equipment are adjustable, the later stage of manufacturing the silica gel barrels with different sizes and styles can be realized only by adjusting the relevant parameters of the die sinking equipment, and the applicability is better.

In this embodiment, the finished mold is preheated in S4, and the preheating temperature is 120 ℃ to 160 ℃. The preheating temperature of the embodiment is 150 ℃, the preheating of the finished product mold in advance is realized, and the waiting starting time required in the later vulcanization process can be greatly reduced.

In this example, the molding time in S5 is 950S to 1050S. In the compression molding process for manufacturing the silica gel barrel, the time of the duration is greatly increased compared with the time of the existing rubber product, and a large number of actual experiments and verifications are carried out in the actual production process, so that the duration is the best in 950s-1050s molding effect in the compression molding operation, the later-stage use is durable, the later-stage time is continuously increased, the effect is not obvious, and the final time is the most suitable in 950s-1050s for the comprehensive efficiency and effect. While in the present embodiment the duration is 1000 s.

In this embodiment, the upper mold temperature is 180 ℃ and the lower mold temperature is 190 ℃. The molded silica gel has the advantages that:

1. high and low temperature resistance (-30 to +260 degree)

2. Waterproof, fireproof and dustproof;

3. the product has the advantages of tensile resistance, tearing resistance, shock resistance and stable performance;

4. high wear resistance, high pressure resistance, softness, no toxicity, no smell and environmental protection;

5. the food grade and the related certification of various exports can be achieved;

therefore, through groping and experiments, the properties of the opening and the body of the silica gel barrel can be different when the temperature of the upper die is 180 ℃ and the temperature of the lower die is 190 ℃, and the requirements of practical use are met.
