    [0001]技术领域
    [0002]本发明涉及压铸模具配件技术领域,尤其涉及一种压铸模具的型腔排气系统。
    [0003]背景技术
    [0004]压铸模具是利用高温融化的金属液注入模具型腔中,然后合上模具压铸成型后,冷却得到所需产品。在注入金属液时,需要通过排气系统将型腔中的空气排出。
    [0005]目前申请号为“201720943606.8 ”公开了“一种压铸模具的型腔排气系统”,该排气系统主要通过设置活塞、排气阀、摆动杆、阀杆及控制杆等部件,通过金属液先推动活塞移动,从而在摆动杆、杆及控制杆的作用下,在金属液流入排气阀之前将排气阀快速关闭,以提高排气阀的相应速度。但是由于金属液的温度极高,在金属液推动活塞移动之前,高温将使得金属液与活塞之间的空气受热膨胀,如此金属液未抵达活塞处时,膨胀后的空气已经推动活塞移动一段距离,如此可提前将排气阀关闭,导致模具型腔内空气无法排除干净,在金属液中形成气泡,从而使得加工出来的产品产生空洞。
    [0006]发明内容
    [0007]本发明的目的是为了解决现有技术中存在的缺点,而提出的一种压铸模具的型腔排气系统。
    [0008]为了实现上述目的,本发明采用了如下技术方案:
    [0009]一种压铸模具的型腔排气系统,包括滑动筒,所述滑动筒的侧壁上固定设置有三角支架,所述三角支架的侧壁上固定连接有排气阀筒,所述排气阀筒侧壁上设有与其内部相通的排气管,所述滑动筒内密封滑动连接有推塞,所述滑动筒下端设有与其连通的第一流道管,所述排气阀筒下端设有与其连通的第二流道管,所述推塞的上端固定连接有弹簧杆,所述三角支架的上端转动连接有压杆,且所述弹簧杆的上端转动连接在压杆的侧壁上,所述排气阀筒内滑动连接有阀芯,所述阀芯的上端固定连接有阀杆,且所述阀杆的上端转动连接在压杆的侧壁上,所述滑动筒的侧壁上开设有排气口,所述第一流道管内壁通过弹簧轴转动连接有两个弧形挡板,且所述弧形挡板上转动连接有连杆,所述连杆远离弧形挡板的一端转动连接有拉杆,所述滑动筒内滑动连接有堵塞,且所述拉杆远离连杆的一端与堵塞固定连接。
    [0010]优选地,所述推塞的下端固定连接有铁质刮环,所述滑动筒内壁上嵌设有多组螺线管,所述推塞的侧壁开设有振动槽,所述振动槽内嵌设有振动发电片,且所述振动发电片通过导电机构与螺线管电性连接,所述振动槽内安装有使振动发电片振动的振动机构。
    [0011]优选地,所述导电机构包括第一导电板与第二导电板,且所述第一导电板嵌设在推塞侧壁上并与振动发电片电性连接,所述第二导电板嵌设在滑动筒内壁上并与螺线管电性连接。
    [0012]优选地,所述振动机构包括复位弹簧与配重杆,所述配重杆滑动设置在振动槽内,所述复位弹簧的一端与配重杆固定连接,所述复位弹簧的另一端固定连接在振动槽内壁上。
    [0013]优选地,多组所述螺线管从上至下等间距分布,相邻两组螺线管间距为10cm。
    [0014]优选地,所述弹簧杆由弹簧与支撑杆组成,其中弹簧的一端固定连接在推塞上端,弹簧的另一端固定设置在滑动筒内顶部,支撑杆一端固定设置在推塞上端,支撑杆另一端与压杆转动连接。
    [0015]本发明具有以下有益效果:
    [0016]1、通过设置排气口、弧形挡板、连杆、拉杆与堵塞等部件,在金属液未抵达滑动筒内、推塞下侧之间,可将推塞与金属液之间的空气通过排气口排出,如此不会推动推塞移动,因此不会提前将排气阀筒关闭,而在金属液抵达时将推动弧形挡板转动,从而在连杆及拉杆作用下使推塞关闭排气口,防止金属液流出。
    [0017]2、通过设置铁质刮环、螺线管等部件,可在使用完毕后,通过各组螺线管依次通电,可吸引铁质刮环上下移动几次,从而将残留在滑动筒内壁上的金属液刮除,避免金属液残留而影响滑动筒与推塞之间的密封效果。

    [0024]实施方式
    [0025]下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。
    [0026]参照图1-4,一种压铸模具的型腔排气系统,包括滑动筒1,滑动筒1的侧壁上固定设置有三角支架3,三角支架3的侧壁上固定连接有排气阀筒6,排气阀筒6侧壁上设有与其内部相通的排气管9,滑动筒1内密封滑动连接有推塞2,滑动筒1下端设有与其连通的第一流道管7,排气阀筒6下端设有与其连通的第二流道管8,推塞2的上端固定连接有弹簧杆4,三角支架3的上端转动连接有压杆5,且弹簧杆4的上端转动连接在压杆5的侧壁上,弹簧杆4由弹簧与支撑杆组成,其中弹簧的一端固定连接在推塞2上端,弹簧的另一端固定设置在滑动筒1内顶部,支撑杆一端固定设置在推塞2上端,支撑杆另一端与压杆5转动连接。
    [0027]排气阀筒6内滑动连接有阀芯10,阀芯10的上端固定连接有阀杆11,且阀杆11的上端转动连接在压杆5的侧壁上,滑动筒1的侧壁上开设有排气口15,第一流道管7内壁通过弹簧轴16转动连接有两个弧形挡板12,需要说明的是,弹簧轴16具体为转轴上安装有一扭簧,扭簧能够使得两个弧形挡板12保持图2状态,在受到向上流动的金属液冲击时,可使弧形挡板12向外侧转动,金属液停止后,则弹簧轴16可拉动弧形挡板12回转复位。
    [0028]且弧形挡板12上转动连接有连杆13,连杆13远离弧形挡板12的一端转动连接有拉杆14,滑动筒1内滑动连接有堵塞18,且拉杆14远离连杆13的一端与堵塞18固定连接。
    [0029]推塞2的下端固定连接有铁质刮环17,滑动筒1内壁上嵌设有多组螺线管25,多组螺线管25从上至下等间距分布,相邻两组螺线管25间距为10cm。
    [0030]推塞2的侧壁开设有振动槽19,振动槽19内嵌设有振动发电片20,且振动发电片20通过导电机构与螺线管25电性连接,振动槽19内安装有使振动发电片20振动的振动机构。导电机构包括第一导电板23与第二导电板24,且第一导电板23嵌设在推塞2侧壁上并与振动发电片20电性连接,第二导电板24嵌设在滑动筒1内壁上并与螺线管25电性连接。
    [0031]振动机构包括复位弹簧22与配重杆21,配重杆21滑动设置在振动槽19内,复位弹簧22的一端与配重杆21固定连接,复位弹簧22的另一端固定连接在振动槽19内壁上。需要说明的是,配重杆21可采用密度较大的材料制成,如铅等质量较大,其惯性也较大,当推塞2被弹簧杆推动下移复位时,在惯性作用下,配重杆21无法同步随推塞2下移,因此将挤压上侧的振动发电片20,而振动发电片20采用压电材料制成在受到机械挤压时,可产生电流,此外振动发电片20与第一导电板23之间设有一放大电路,可将产生电流放大,当第一导电板23与第二导电板24接触时,可将放大后的电流输向对应的螺线管25,使螺线管25通电并产生较强的磁力。
    [0032]本发明中,与背景技术中所应用的排气系统相通,金属液将先流入第一流道管7内。在金属液抵达滑动筒1内部、推塞2下侧之间,则金属液与推塞2之间空气在膨胀后,将从滑动筒1两侧的排气口15向外排出。因此空气不会推动推塞2上移,而当金属液流动至弧形挡板12下侧并继续向上流动时,流动的金属液将使得两个弧形挡板12向外侧翻转,如此可通过连杆13推动两个拉杆14向外侧移动,因此拉杆14将拉动堵塞18进入排气口15内,堵塞18可将排气口15堵住。当金属液流入滑动筒1内时将推动推塞2上移,而不会从排气口15流出。推塞2也将推动弹簧杆4上移,从而使得压杆5的左端上移而右端下移,并推动阀杆11及阀芯10下移,从而将第二流道管8上端堵住,以在型腔内空气由第二流道管8、排气阀筒6及排气管9排出后,防止金属液流入排气阀筒6内。
    [0033]故综上所述,本发明在金属液未抵达滑动筒1内、推塞2下侧之间,可将推塞2与金属液之间的空气通过排气口排出,如此不会推动推塞移动,因此不会提前将排气阀筒6关闭,从而能够使模具型腔内的空气能够充分排出,避免在型腔内产生气泡而导致加工出来的产品产生空洞。
    [0034]生产完毕后,滑动筒1内的金属液从第一流道管7流出后,推塞2也将在弹簧杆4上弹簧的作用下移。而在惯性作用下,配重杆21来不及随推塞2一起下移如此可挤压上侧的振动发电片20,迫使振动发电片20产生机械形变而产生电流,当第一导电板23与最上侧的第二导电板24接触时,产生的电流经过放大电路放大后通入将通最上侧的螺线管25,螺线管25通电后将产生磁性并吸引铁质刮环17带动推塞2上移一段距离,随后配重杆21也停止挤压振动发电片20,最上侧螺线管25断电后不再吸引铁质刮环17,如此弹簧杆4继续推动推塞2下移,此时配重杆21继续在惯性作用下挤压振动发电片20,同时滑动筒1内壁上中间部分第二导电板24与第一导电板23接触,可使中间部分的螺线管25通电,从而又将吸引铁质刮环17上移一小段距离。同理,对于最下侧的螺线管25也将通断电依次并吸引铁质刮环17上移一小段距离。
    [0035]因此本装置在生产完毕后,在导电机构、振动机构及螺线管25等部件的作用下,推塞2及其上侧的铁质刮环17将多次上下移动,铁质刮环17将残留在滑动筒1内壁上的金属液快速刮除,并由第一流道管7排出,防止金属液在滑动筒1内壁上冷却成型,而影响滑动筒1内壁与推塞2之间的密封性能。
    [0036]以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,根据本发明的技术方案及其发明构思加以等同替换或改变,都应涵盖在本发明的保护范围之内。
