Description

Technical Field

[0001] The utility model specifically relates to a sealing ring mould which is convenient for overall demoulding. Background Art

[0002] The sealing ring rubber mold is a common mold structure used for the molding production of ordinary vulcanizers. The operator needs to manually feed the material with a feeder, then heat and vulcanize it, and finally open the mold to take out the product. For some rubber materials with high viscosity and good fluidity, the product and the flash will stick to the lower mold during demolding. When the demolding is blown out by an air gun, the flash strength is not enough, and it will break. The whole mold product will split into a random number of small groups and splash everywhere, which is not easy to collect and cannot achieve the purpose of overall demolding. After the product is blown out, the flash is uneven and the thinner flash sticks to the lower mold, which is also difficult to remove, resulting in the generation of aging rubber. The production staff needs to spend extra time to manually remove the residual rubber on these molds, resulting in low production efficiency and affecting the processing effect. For this reason, we propose a sealing ring mold that is easy to demold as a whole. Utility Model Content

[0008] The leather grain is arranged on the upper mold to improve the roughness of the upper mold.

[0009] Preferably, the leather grain is arranged at two locations, the other leather grain is arranged on the lower mold, and the two leather grains correspond to each other in the vertical direction.

[0010] Preferably, a guide post is fixed on the lower surface of the upper mold, and a guide sleeve corresponding to the guide post is provided on the inner edge of the lower mold.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: a sealing ring mold that is easy to demould as a whole, comprising:

[0025] An upper mold 1 is provided with a first cavity 4;

[0026] The lower mold 2 is arranged on the lower surface of the upper mold 1, and a sealing ring body 3 is formed between the lower mold 2 and the upper mold 1;

[0027] The lower mold 2 includes a residual material groove 6, a grid groove 7 and a second cavity 8. The residual material groove 6 and the second cavity 8 are arranged side by side on the lower mold 2, and a grid groove 7 for reinforcing the flash of the sealing ring body 3 is arranged between the residual material groove 6 and the second cavity 8, so as to strengthen the strength of the flash of the sealing ring body 3, so that multiple sealing ring bodies 3 are better connected to form a whole, and then the whole demoulding is facilitated, and the flash is reduced from adhering to the mold, resulting in the need for manual cleaning in the later stage;

[0028] The leather grain 5 is arranged on the upper mold 1 to improve the roughness of the upper mold 1. By arranging the leather grain on the upper mold 1 outside the first cavity 4, it is convenient to reduce the adhesion between the flash and the mold during demolding, and at the same time, it can effectively prevent the flash from remaining on the mold and causing the generation of aging glue.

[0029] In this embodiment, preferably, two leather grains 5 are provided, and another leather grain 5 is provided on the lower mold 2, and the two leather grains 5 correspond to each other in the vertical direction, so as to better reduce the adhesion between the flash edge of the sealing ring body 3 and the mold and improve the convenience of later demolding.

[0030] In this embodiment, preferably, a guide post 101 is fixed to the lower surface of the upper mold 1, and a guide sleeve 201 corresponding to the guide post 101 is provided on the inner edge of the lower mold 2 to facilitate alignment during mold closing.

[0031] In this embodiment, preferably, the guide post 101 is tapered, and the end of the guide post 101 with the smallest outer diameter faces the guide sleeve 201, so that the guide post 101 can be better extended into the inner side of the guide sleeve 201 when the mold is closed.

[0032] In this embodiment, preferably, a slot is provided inside the upper mold 1, and a return spring 102 is disposed inside the slot to facilitate separation of the upper mold 1 and the lower mold 2 after mold closing, so as to facilitate later demoulding.

[0033] In this embodiment, preferably, the depth of the leather grain 5 is 0.004 mm-0.006 mm, so as to better improve the roughness of the mold, reduce the adhesion between the sealing ring flash and the mold through the leather grain, and prevent the flash from sticking to the mold to form aging glue.

[0034] In this embodiment, preferably, the depth of the grid groove 7 is 0.2 mm and the cross-sectional diameter is 0.6 mm.

[0035] In this embodiment, preferably, a lifting rod 103 is fixed to the side wall of the upper mold 1 to facilitate lifting or lowering the upper mold 1.

[0036] The working principle and use process of the utility model are as follows: during production, a grid groove 7 is provided on the lower mold 2 at a distance of 0.3mm-0.5mm from the second cavity 8, the grid groove 7 extends outside to the residual material groove 6, and is cross-distributed around each second cavity 8, and the upper mold 1 is processed with leather grain 5 around the first cavity 4, the leather grain specification is 3400-VDI33, and the depth is 0.004mm-0.006mm, and the lower mold 2 is also processed with leather grain 5. Through the improvement in the above manner, the addition of the grid groove 7 is equivalent to adding reinforcing ribs to the flash of the sealing ring body 3, thereby increasing the strength of the flash; the leather grain 5 is processed on the upper and lower molds, thereby increasing the roughness of the contact surface between the upper and lower molds and the flash, and reducing the adhesion between the sealing ring body 3 and the flash and the mold. Then, during product production, all products are connected together through the flash, and when the air gun is blown up to demould, the production personnel can remove a whole piece of product at a time, and there is no more rubber residue on the mold, which greatly shortens the auxiliary time of production and improves the processing efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
