Description
Technical Field
The utility model belongs to the technical field of the mould technique and specifically relates to a mould for hydrogen fuel cell sealing washer is related to.
Background
The power battery is used as the heart of the electric automobile and is the key for the development of the new energy automobile industry, and the development performance of the power battery industry in China is obvious under the support of a series of policy measures and the efforts of all parties. The yield and sales of domestic new energy vehicles are predicted to keep rapid increase in the next 5 years, and the annual composite growth rate is predicted to exceed 30%. The new energy automobile market shows explosive growth, and the scale of the power battery is directly and rapidly increased. According to the data reported by the industry, the output value of the Chinese power battery is 380 hundred million yuan, the year 2015 is increased by 262 percent, and the output value is close to that of a digital lithium battery. In 2016, the output value of the Chinese power battery is 645 hundred million yuan, which exceeds the scale of the traditional digital lithium battery for the first time, and the lithium battery becomes the largest area in the consumption structure of the lithium battery. With the coming of a new round of popularization policy and the influence of improvement of lithium battery production technology, cost reduction and the like in the future, the demand of the power battery for the new energy automobile is increased at a high speed in the next 5 years, the output of the power battery for the automobile in China is 30.8GWH in 2016, and the output of the power lithium battery for the automobile in China is expected to reach 141GWH in 2020.
The hydrogen fuel cell is widely applied to automobiles, and the sealing ring of the hydrogen fuel cell is static sealing to seal hydrogen, and the hydrogen molecular weight is very small, so that the requirement on the sealing ring of the sealing gasket is very high. When the sealing ring is produced, the flash is easy to be stuck to the film after the existing die product is formed, and when the flash and the product are separated, the product is easy to be damaged, so that the reject ratio is increased, and the rubber sealant is scrapped, thereby increasing the production cost and simultaneously reducing the processing efficiency.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the mold for the hydrogen fuel cell sealing ring is provided in order to solve the problems that after the existing mold product is molded, burrs are easy to be adhered to the film, when the burrs and the product are separated, the product is easy to be damaged, the reject ratio is increased, and rubber sealant is scrapped, so that the production cost is increased, and meanwhile, the processing efficiency is reduced.
The utility model provides a technical scheme that its technical problem adopted is: the mold for the hydrogen fuel cell sealing ring comprises an upper mold and a lower mold, wherein a cavity is formed between the upper mold and the lower mold, an inwards-concave groove is formed in one side of the cross section of the cavity, an overflow groove, an anti-sticking film groove and a flash groove are formed between the upper mold and the lower mold, the overflow groove, the anti-sticking film groove and the flash groove are located in one side of the cavity, the anti-sticking film groove is located between the overflow groove and the flash groove, the flash groove is located in one side close to the cavity, and the cavity, the flash groove, the anti-sticking film groove and the overflow groove are sequentially communicated. Through setting up overflow launder, anti-sticking film groove and overlap groove in die cavity one side between last mould and lower mould, the overflow launder plays the material overflow when feeding for the commodity circulation can be filled the die cavity and can not appear the cavitation, and the overlap groove can be divided in order to make product and rim charge simultaneously, and anti-sticking agent has been smeared in the anti-sticking film inslot, prevents that the overlap from gluing the phenomenon on the product.
Further, the cross section of the overflow groove is in a hexagonal structure.
Furthermore, the cross section shapes of the anti-sticking film groove and the flash groove are both diamond structures.
The utility model has the advantages that: the utility model discloses mould for hydrogen fuel cell sealing washer is when using, die cavity one side through between last mould and lower mould sets up the overflow launder, antiseized membrane groove and flash groove, the overflow launder plays the material overflow when feeding, make the commodity circulation can fill the die cavity and can not appear the cavitation, flash groove can be parted in order to make product and rim charge simultaneously, antiseized inslot is paintd and is had antiseized agent, prevent that the flash from gluing the present on the product, the easy mucosa after having avoided current mould product shaping, make the product damage easily when the drawing of patterns, the disqualification rate has been increased, and lead to the rubber sealant to scrap, thereby manufacturing cost has been increased, the problem of machining efficiency has also been reduced simultaneously.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention.
In the figure: 1. the device comprises an upper die, a lower die, a die cavity, a cavity, 4, an overflow groove, 5, an anti-sticking film groove, 6, a flash groove, 7 and a groove.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, a mold for a hydrogen fuel cell sealing ring comprises an upper mold 1 and a lower mold 2, wherein a cavity 3 is formed between the upper mold 1 and the lower mold 2, an inwardly recessed groove 7 is formed in one side of the cross section of the cavity 3, an overflow groove 4, an anti-sticking film groove 5 and a flash groove 6 are formed between the upper mold 1 and the lower mold 2, the overflow groove 4, the anti-sticking film groove 5 and the flash groove 6 are located in one side of the cavity 3, the anti-sticking film groove 5 is located between the overflow groove 4 and the flash groove 6, the flash groove 6 is located in one side close to the cavity 3, and the cavity 3, the flash groove 6, the anti-sticking film groove 5 and the overflow groove 4 are sequentially communicated.
