Description
技术领域
本发明用于橡胶垫领域,特别是涉及一种橡胶垫的制作方法及橡胶垫。
背景技术
目前橡胶垫制作过程中,由于模具上加装有定位凸点,定位凸点用于先将板件进行定位,然后注胶,因板件较薄,注胶时会受压变形,而且在定位点处无法包胶,防锈经常处理不好,影响产品寿命。
发明内容
本发明的目的在于至少解决现有技术中存在的技术问题之一,提供一种橡胶垫的制作方法及橡胶垫,制作橡胶垫时板件不易变形,且橡胶垫包胶完整,有效提升使用寿命。
第一方面,本发明的实施例提供了一种橡胶垫的制作方法,包括以下步骤:
预制第一板件和第二板件,对第一板件的表面用萘钠处理,第二板件上开设多个通孔;
预制多个尺寸小于模具模腔的胶片;
模腔中放入第一板件,在第一板件上叠加一层胶片,在胶片上叠加第二板件,在第二板件上继续叠加一层胶片,在第一板件和第二板件的侧面包一层胶,向模腔中注胶,以使胶料填充胶片与模腔之间的间隙;
合模硫化。
上述技术方案具有如下优点或有益效果:由于预制的胶片的尺寸小于模腔的尺寸,所以胶片放在模腔中会与模腔之间存在间隙,向模腔中注入胶料以将胶片与模腔之间的缝隙进行填充弥补,注入的胶料除了进入胶片与模腔之间的缝隙中之外,合模硫化的过程中,部分胶料还会穿过第二板件的通孔进入第二板件与胶片的叠合缝中,这样避免了注入的胶料堆积在第二板件中部而导致第二板件在合模过程中被压弯,致使出现橡胶垫厚度不均匀的问题,而且第一板件和第二板件侧边包胶防止第一板件和第二板件外漏,保证了加工出的橡胶垫包胶完整,产品不易生锈,使用寿命更高。
作为本发明第一方面的技术改进,模腔中放入第一板件,在该第一板件上叠放多层第二板件和多层胶片,第二板件和胶片交替式叠加布置。
作为本发明第一方面的技术改进,第二板件预制好之后,在第二板件的表面进行脱脂、喷砂,然后涂胶。
第二方面,本发明提供了一种橡胶垫,采用以上任意一项所述橡胶垫的制作方法进行制作。

目前常见的橡胶垫制作方法是,首先叠放三层胶料,三层胶料中间放铁板,然后通过模具进行模压,这样制作出来的橡胶垫厚度不均,产品的垂向刚度无法保证,此外,橡胶垫制作过程中,由于模具上加装有定位凸点,定位凸点用于先将板件进行定位,然后注胶,因板件较薄,注胶时会受压变形,而且在定位点处无法包胶,防锈经常处理不好,影响产品寿命。
参见图1~图5,基于上述缺点本发明提供了一种橡胶垫的制作方法,包括以下步骤:
预制第一板件1和第二板件2;
对第一板件1的表面用萘钠处理,第二板件2上开设多个通孔20;
预制多个尺寸小于模具模腔的胶片3;
模腔中放入第一板件1,在第一板件1上叠加一层胶片3,然后在胶片3上叠加第二板件2,在该第二板件2上继续叠加一层胶片3,在第一板件1和第二板件2的侧面包一层胶,向模腔中注胶,以使胶料填充胶片3与模腔之间的间隙;
合模硫化,以使胶片3与第一板件1、第二板件2连接。
具体的,由于预制的胶片3的尺寸小于模腔的尺寸,所以胶片3放在模腔中会与模腔之间存在间隙,向模腔中注入胶料以将胶片3与模腔之间的缝隙进行填充弥补,由于第二板件2上开设有通孔20,所以避免了注入的胶料堆积在第二板件2中部而导致第二板件2在合模过程中被压弯,保证了产品的垂向刚度,而且第一板件和第二板件侧边包胶防止第一板件和第二板件外漏,使得加工出的产品不易生锈,使用寿命更高。
在一些实施例中,模腔中放入第一板件1,在该第一板件1上叠放多层第二板件2和多层胶片3,第二板件2和胶片3交替式叠加布置,从而加工出更厚的橡胶垫。
在一些实施例中,第二板件2预制好之后,在第二板件2的表面进行脱脂、喷砂,然后涂胶粘剂,以提高第二板件2与胶片3的连接性能,其中第二板件2采用钢板。
此外,本发明的实施例还提供了一种橡胶垫,采用以上任意一项橡胶垫的制作方法制作而成。
当然,本发明创造并不局限于上述实施方式,熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换,这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
