Description

Technical Field

[0001] The utility model belongs to the technical field of rubber gasket manufacturing, in particular to hot pressing molding equipment for low-temperature resistant rubber sealing gaskets. Background Art

[0002] Low-temperature resistant rubber can still have good elasticity in low-temperature environments. It is formed by adding sulfide to the rubber raw materials and melt mixing. It is usually used in aerospace, polar scientific research, low-temperature storage tank sealing and other fields. During hot pressing, low-temperature resistant rubber needs to maintain its performance at a continuous low temperature. Therefore, the temperature control during the hot pressing process is more stringent. It is necessary to avoid excessive temperature causing the material performance to deteriorate. The hot pressing time needs to be adjusted according to the characteristics of the material and the requirements of the product to ensure that the material is fully cured and the performance is stable. In addition, compared with ordinary rubber, low-temperature resistant rubber also needs to be properly cooled after hot pressing to ensure that the quality meets the requirements.

Under the thrust of the cylinder 201, the flip sleeve 204 presses the heating wire tube 203c-1 into the hot pressing cylinder 202b of the hot pressing plate 202, so that the heating wire tube 203c-1 is pressed against the rubber gasket mold plate 101. The rubber strip on the right side is heated and pressurized to melt the rubber strip and be pressed into the gasket mold ring groove 101a of the rubber gasket mold plate 101, and the temperature control plate 203 is pulled up by the cylinder 201. The temperature control plate 203 is turned over by the servo motor, and the cooling liquid cylinder 203b on one side of the temperature control plate 203 is pressed into the hot pressing cylinder barrel 202b under the push of the cylinder 201, so that the cooling liquid cylinder 202b cools the rubber in the gasket mold ring groove 101a, and at the same time, the cooling liquid tank 103a in the cooling liquid pool 103 on the base 1 cools the gasket mold ring groove 101a.

[0028] Specifically, a rubber gasket mold plate 101 is fixedly installed above the pedestal 1, and a gasket mold ring groove 101a is opened on the upper side plate of the rubber gasket mold plate 101. A side plate 102 is fixedly provided on one side of the pedestal 1. A horizontal plate 102a is fixedly provided on the side of the side plate 102 near the top of the pedestal 1. The cylinder 201 is fixedly installed above the horizontal plate 102a. The telescopic end of the cylinder 201 passes through the horizontal plate 102a and is fixedly connected to the upper plate surface of the flip sleeve 204. A set of guide pillars are fixedly provided on the upper side plate surface of the hot pressing plate 202. 202a, a group of through holes matching the guide pillars 202a are provided on the surface of the horizontal plate 102a and the flip sleeve 204, and the guide pillars 202a respectively pass through the through holes on the surface of the flip sleeve 204 and are slidably sleeved in each through hole of the horizontal plate 102a, and flip arms 204a are fixed at both ends of the plate surface on one side of the flip sleeve 204 close to the hot pressing plate 202, and rotating shafts 203a are fixed on both sides of the temperature control plate 203, and the rotating shafts 203a on both sides are rotatably sleeved between the flip arms 204a at both ends.

[0029] Furthermore, the rotating shaft 203a on one side of the temperature control plate 203 passes through the flip arm 204a and is connected to the output shaft of the servo motor through a belt.

[0030] Furthermore, a hot pressing cylinder barrel 202b matching the gasket mold ring groove 101a is provided on the surface of the hot pressing plate 202, and the opening of the hot pressing cylinder barrel 202b is upward.

[0031] Furthermore, a group of cooling liquid cylinders 203b matching the hot pressing cylinder barrel 202b are fixedly installed on one side of the temperature control plate 203, and each cooling liquid cylinder 203b is connected to the cylinder body through a pipeline.

[0032] Furthermore, a heating wire plate 203c is fixedly installed on one side of the temperature control plate 203 away from the cooling liquid cylinder 203b, and a group of heating wire tubes 203c-1 matching the hot pressing cylinder 202b are fixedly installed on the plate surface of the heating wire plate 203c.

[0033] Furthermore, a top cap 202a-1 is fixedly provided at one end of the guide post 202a away from the hot pressing plate 202, and a return spring 202a-2 is sleeved on the outer side of the guide post 202a between the top cap 202a-1 and the cross plate 102a.

[0034] The operation process of this embodiment is as follows:

[0035] The rubber strip raw material is placed above the rubber gasket mold disk 101, and the cylinder 201 pushes the flip sleeve 204 to press the electric heating wire tube 203c-1 into the hot pressing cylinder 202b, and heats the rubber strip raw material on the rubber gasket mold disk 101, so that it melts and flows into the gasket mold ring groove 101a. The cylinder 201 pulls up the flip sleeve 204, and at the same time, the hot pressing plate 202 is pulled up under the tension of the return spring 202a-2. The servo motor drives the belt to rotate the rotating shaft 203a, causing the temperature control plate 204 to flip, so that the cooling liquid cylinder 203b is pressed into the hot pressing cylinder 202b to cool the rubber in the gasket mold ring groove 101a.

[0036] Example 2

[0037] See also Figures 1 to 5 On the basis of Example 1, a cooling liquid pool 103 is opened above the table top of the base 1, and the gasket mold ring groove 101a is cooled by the cooling liquid tank 103a in the cooling liquid pool 103 to prevent the rubber from being in a melted state and the temperature being continuously too high, causing the sulfide inside the molten rubber to volatilize, thereby causing the rubber's low-temperature resistance to decrease.

[0038] Specifically, a coolant tank groove 101a-1 is provided on the lower side surface of the rubber gasket mold plate 101, and a set of coolant tanks 103a matching the gasket mold ring groove 101a are fixedly installed in the coolant pool 103, and each coolant tank 103a is sleeved in each coolant tank groove 101a-1.

[0039] The operation process of this embodiment is as follows:

[0040] The raw material of the rubber strip is heated and melted by the electric heating wire tube 203c-1 and flows into the gasket mold ring groove 101a. The cooling liquid tank 103a in the cooling liquid pool 103 transfers the heat of the high-temperature hot-melt rubber to the coolant to cool the shaped hot-melt rubber and prevent the continuous high temperature from causing the sulfide inside the rubber to volatilize and reduce the rubber's low-temperature resistance.
