Description
本申请涉及模具技术领域，具体涉及一种模具及模具中的模仁的装卸方法。
在注塑成型过程中，模仁表面通常会出现粘胶、白点、脏污等不良外观问题，现有技术中通常采用在成型机台上直接擦拭模仁，或拆卸整套模具来取下模仁进行清理。
在实现本申请的过程中，发明人发现现有技术中至少存在如下问题：在成型机台上擦拭时，由于模仁都是采用一种表面镀化学镍方式制作而成，镍的材质较软，因成型机台的空间限制，在擦拭过程中模仁较容易因为人为操作不当而受到损伤；当拆卸整套模具取模仁时，由于需要模具降温后才可拆卸并取出模仁，之后还需重新装配模具及加温调试，整个过程耗时较长。
申请内容
鉴于以上内容，有必要提出一种模具及模具中的模仁的装卸方法，以解决上述问题。
本申请的实施例提供一种模具，包括：
模座，所述模座的表面开设有一容置槽；
模仁件，所述模仁件具有铁磁性且收容于所述容置槽内，所述模仁件包括模仁；及
磁吸件，固定于所述容置槽内，用于磁吸固定所述容置槽内的所述模仁。
上述模具中的模仁件具有铁磁性，磁吸件具有磁矩，可在其周边产生磁场，吸附模仁件，使得模仁件固定在容置槽内，当模仁有外观问题或者需要更换时， 只要通过移取工具克服磁吸件的吸引力移取单个模仁即可，模仁的拆卸和装配均较为方便，可以大量节约时间，减少模仁损伤几率。
在一些实施例中，所述磁吸件具有一收容腔，所述模仁的靠近所述容置槽的槽底的一端插装于所述磁吸件的收容腔内。
如此，在模仁插装在收容腔内后，收容腔可限制模仁的摆动，且磁吸件的靠近容置槽的轴线的一侧可吸附模仁，将模仁定位于容置槽内的准确位置，防止其在容置槽内晃动。
在一些实施例中，所述磁吸件为多个，且围绕所述容置槽的轴线设置，所述收容腔由多个所述磁吸件围设形成。
如此，在模仁插装在多个磁吸件围设形成的收容腔内后，收容腔可限制模仁的摆动，且磁吸件的靠近容置槽的轴线的一侧可吸附模仁，将模仁定位于容置腔内的准确位置，防止其在容置槽内晃动，并且，在其中一个磁吸件损坏时只需更换此磁吸件，减少了更换成本。
在一些实施例中，所述容置槽的槽壁开设有固定槽，所述磁吸件至少部分收容于所述固定槽内。
如此，固定槽可收容磁吸件，且可防止其沿着容置槽的轴线方向运动。
在一些实施例中，所述磁吸件设于所述容置槽的槽底，且与所述模仁的靠近所述容置槽槽底的一端吸附固定于所述磁吸件。
如此，磁吸件可直接吸附模仁将其进行固定，当模仁有外观问题或者需要更换时，只要通过移取工具克服磁吸件的吸引力移取模仁即可。
在一些实施例中，所述模具还包括：
紧固件，固定于所述容置槽的槽底，所述紧固件靠近所述模仁的一侧开设有紧固槽，所述磁铁收容且固定于所述紧固槽内。
如此，紧固件固定于容置槽的槽底，磁吸件收容且固定于紧固件的紧固槽内，以实现将磁吸件固定在容置槽内。
在一些实施例中，所述紧固件与所述容置槽的固定关系为焊接、紧配合、胶粘中的至少一种。
如此，可根据实际需要选用相应的固定连接方式，将紧固件固定连接于容 置槽内。
在一些实施例中，所述模仁件还包括：
调节件，设于所述模仁靠近所述容置槽的槽底的一端，以调节所述模仁相对于容置槽的槽底的一端的位置，所述模仁和所述调节件中的至少一者具有铁磁性。
如此，可通过调节件对模仁相对于容置槽的槽底的一端的位置，保证加工后的产品的精度。
在一些实施例中，所述调节件包括：
调节部，包括相对的抵持端和旋入端，所述抵持端抵持于所述磁吸件，所述旋入端旋入所述模仁的靠近所述容置槽的槽底的一端内，通过调整所述旋入端在所述模仁内的旋入深度可调节所述模仁相对于所述容置槽的槽底的一端的位置。
如此，调节件可通过调整旋入端在模仁内的旋入深度来调节模仁在容置槽内的位置，且抵持端可抵持于磁吸件上，保证了模仁的稳固性。
在一些实施例中，所述调节件包括：
支撑部，抵持于所述磁吸件，且与所述模仁的靠近所述容置槽的槽底的一端存在调节间隙；
调节部，包括相对的抵持端和旋入端，所述抵持端与所述支撑部连接，所述抵持端可选择地抵持于所述磁吸件，所述旋入端旋入所述模仁的靠近所述容置槽的槽底的一端内，通过调整所述旋入端在所述模仁内的旋入深度可调节所述调节间隙的大小。
如此，调节件可通过调整旋入端在模仁内的旋入深度可调节所述调节间隙的大小，从而调节模仁在容置槽内的位置，并且，支撑部可抵持于磁吸件，或者支撑部和调节部的抵持端共同抵持于磁吸件，增大了抵持面积，从而保证了模仁的稳固性。
在一些实施例中，所述模座包括层叠设置的第一模板和第二模板，所述模压面为所述第一模板的背离所述第二模板的表面，所述容置槽的一端贯穿所述第一模板的所述模压面，
另一端贯穿所述第一模板的与所述模压面相对的表面，所述磁吸件位于所述第一模板内；或者，所述容置槽的另一端贯穿所述第一模板的与所述模压面相对的表面且延伸至所述第二模板内，所述磁吸件位于所述第二模板内。
如此，当容置槽仅开设于第一模板内时，容置槽的加工工艺较为简单；当容置槽开设于第一模板和第二模板内时，在安装时可先将磁吸件装设于第二模板内，然后第二模板对接第一模板后在安装模仁件，安装过程较为简单。
在一些实施例中，磁吸件为永磁铁或电磁铁。
如此，在使用过程中可通过永磁铁或电磁铁将模仁磁吸固定，当模仁有外观问题或者模仁需要更换时，只要通过移取工具克服永磁铁的吸引力移取单个模仁，或者给电磁铁断电，使其不具有磁场，从而没有吸引力，然后通过移取工具移取模仁，模仁的拆卸和装配均较为方便。
在一些实施例中，所述模具的模穴数为一个、两个、四个、八个、十二个、十六个、三十二个或六十四个。
如此，可根据需要选择相应模穴数的模具，其中模具可一次成型多个产品，产品的加工效率较高，相应的也减少了模具的使用次数，延长了模具的使用寿命。
本申请的实施例还提出了一种上述的模具中的模仁的装卸方法，沿所述模仁背离所述磁吸件的方向将所述模仁取出或装设于所述模座的容置槽内。
上述方法在当模仁有外观问题或者需要更换时，只要通过移取工具沿所述模仁背离所述磁吸件的方向克服磁吸件的吸引力移取单个模仁件即可，不需要拆卸整套模具，模仁的拆卸和装配均较为方便，可以大量节约时间，减少模仁损伤几率。

请参见图1，本申请的第一实施例提出了一种模具100，可方便装拆模仁，该模具100可以为压制成型模具、注射成型模具、挤出成型模具、吹塑成型模具、真空成型模具，但不限于此。模具100的模穴数为一个、两个、四个、八个、十二个、十六个、三十二个或六十四个，如此，可根据需要选择相应模穴数的模具，其中模具可一次成型多个产品，产品的加工效率较高，相应的也减少了模具的使用次数，延长了模具的使用寿命。产品可为光学镜片，例如，手机镜头镜片、车载镜头镜片及安防镜头镜片。当然，模具100并不限于注塑精密的光学镜片，还可以注塑其他塑料产品。
模具100包括模座10、模仁件20、磁吸件30及紧固件40。
请参见图2与图3，模座10包括模压面11，模压面11开设有容置槽12。模仁件20具有铁磁性且收容于容置槽12内，模仁件20包括模仁21。磁吸件30固定于容置槽12内，用于磁吸固定模仁件20。
模座10的数量为两个，且可对接在一起使用。具体地，两个模座10的结构相似，其中一模座10包括依次层叠设置的第一模板13、第二模板14及第三模板15，第一模板13、第二模板14及第三模板15之间通过螺栓固定连接在一起，另一模座10包括第一模板13、第二模板14。其中一模座10的第一模板13与另一模座10的第一模板13对接在一起使用，模压面11为两个第一模板13对接的表面。
在本实施例中，容置槽12的一端贯穿第一模板13的模压面11，另一端贯穿第一模板13的与所述模压面11相对的表面，容置槽12的槽底为第二模板14的靠近第一模板13的表面。
可以理解地，在其他的实施例中，容置槽12的一端贯穿第一模板13的模压面11，另一端贯穿第一模板13的与所述模压面11相对的表面且延伸至第二模板14内，容置槽12的槽底位于第二模板14内，磁吸件30的远离容置槽12的槽底的一端与第二模板14的靠近第一模板13的表面平齐。
当容置槽12仅开设于第一模板13内时，容置槽12的加工工艺较为简单；当容置槽12开设于第一模板13和第二模板14内时，在安装时可先将磁吸件30装设于第二模板14内，然后第二模板14对接第一模板13后在安装模仁件20，安装过程较为简单。
请参见图3和图4，模仁件20为两个且分别设置在两个模座10的容置槽12内，且对接在一起，具体地，两个模仁21对接且在对接位置均形成有一型腔211，两个模仁21的型腔211对接在一起可形成产品型腔。模仁21上还形成有连通型腔211的流道212(图中仅示出部分结构)，以将熔料注塑至型腔211内。
在本实施例中，模座10还包括灌嘴、顶针、上顶板、下顶板等结构，由于此结构属于模座10的常规内部结构，故不再赘述。
在本实施例中，模仁21均大致呈柱状，具体地，模仁21大致呈圆柱状或棱柱状。当然，模仁21的形状并不限于上述的实施方式，而可以根据实际的需要设计为其他形状。
在一些实施例中，模仁件20还包括调节件22。调节件22设于模仁21靠近容置槽12的槽底的一端，以调节模仁21相对于容置槽12的槽底的一端的位置，保证加工后的产品的精度。在本实施例中，模仁21具有铁磁性，调节件22不具有铁磁性。
可以理解地，在其他的实施例中，调节件22具有铁磁性，模仁21部具有铁磁性。
可以理解地，在其他的实施例中，模仁21和调节件22均具有铁磁性。
其中，调节件22包括支撑部221和调节部222。
支撑部221抵持于磁吸件30，且与模仁21的靠近容置槽12的槽底的一端存在调节间隙。其中，调节间隙大于等于零。具体到本实施例中，如图3所示，调节间隙等于零，也即是说，支撑部221的背离容置槽12的槽底的一侧抵持于模仁21。
可以理解地，在其他的实施例中，调节间隙可大于0，例如0.1mm。但不限于此，具体可根据实际需要进行设定。
调节部222包括相对的抵持端2221和旋入端2222，抵持端2221与支撑部221连接，抵持端2221可选择地抵持于磁吸件30，旋入端2222旋入模仁12的靠近容置槽12的槽底的一端内，通过调整旋入端2222在模仁12内的旋入深度可调节所述调节间隙的大小。
在本实施例中，抵持端2221穿设于支撑部221内部，且可通过胶粘、焊接等固定连接方式与支撑部221连接在一起，可以理解地，也可通过螺纹连接的方式与支撑部221可拆卸地连接。
在本实施例中，支撑部221为一垫片，调节部222为一螺栓，抵持端2221对应螺栓的螺头，旋入端2222对应螺柱远离螺头的一端。
在本实施例中，抵持端2221与容置槽12的槽底之间的距离，等于支撑部221的靠近容置槽12的槽底的一端与容置槽12的槽底之间的距离；也即抵持端2221与支撑部221的靠近容置槽12的槽底的一端在同一水平高度，此时，抵持端2221与支撑部221均抵持在磁吸件30上。
可以理解地，在其他地实施例中，请参见图5，抵持端2221与容置槽12的槽底之间的距离，大于支撑部221靠近容置槽12的槽底的一端与容置槽12的槽底之间的距离；也即抵持端2221位于支撑部221靠近容置槽12的槽底一端的上方，此时支撑部221抵持在磁吸件30上，抵持端2221不抵持在磁吸件30上。
可以理解地，在其他地实施例中，请参见图6，支撑部222可以省略。此时，调节部221的抵持端2221抵持于磁吸件30，旋入端2222旋入模仁21的靠近容置槽12的槽底的一端内，通过调整旋入端2222在模仁21内的旋入深度可调节模仁21相对于容置槽12的槽底的一端的位置。
磁吸件30为永磁铁或电磁铁。需要说明的是，磁铁分为“永久磁铁”和“非永久磁铁”，永久磁铁可以是天然产物，又称天然磁石，也可以由人工制造；非永久性磁铁，例如电磁铁，只有在某些条件下例如通电才会出现磁性。磁吸件30设于容置槽12的槽底，且模仁21的靠近容置槽12槽底的一端吸附固定于磁吸件30。
当磁吸件30为永磁铁时，永磁铁可吸附固定模仁件20，当模仁21有外观问题或者模仁需要更换时，需先将两个模座10分离，然后通过移取工具克服永磁铁的吸引力取出模仁件20。
当磁吸件30为电磁铁时，电磁铁可吸附固定模仁件20，当模仁21有外观问题或者模仁需要更换时，先将两个模座10分离，然后给电磁铁断电，使其不具有磁场，从而没有吸引力，然后通过移取工具移取模仁21。
紧固件40固定于容置槽12的槽底，紧固件40靠近模仁21的一侧开设有紧固槽41，磁吸件30收容且固定于紧固槽41内。
在本实施例中，紧固件40大致为柱状，例如圆柱、棱柱。紧固件40通过紧配合、焊接或胶粘的方式固定在容置槽12内。具体地，紧固件40为一磁吸套，紧固件40具有阶梯状的紧固槽41，具体地，紧固槽41包括相连通的第一槽411和第二槽412，第一槽411相对于第二槽412远离容置槽12的槽底设置，且第一槽411和第二槽412的横截面均为圆形，第一槽411的直径大于第二槽412的直径，磁吸件30可收容于紧固槽41的第一槽411内；第二槽412的槽壁设置有螺纹段，磁吸件30的对应第二槽412的位置开设有螺纹孔，可利用螺柱42将其一端旋入磁吸件30的螺纹孔内，另一端旋入紧固槽41的第二槽412内，实现将磁吸件30固定在紧固件40内，在使用时，先将磁吸件30放置于第一槽411内，然后利用螺柱42依次旋入第二槽412及磁吸件30的螺纹孔内，实现磁吸件30和紧固件40固定连接在一起；接着将磁吸套通过紧配合的方式放置于容置槽12内，进一步地，还可将磁吸套通过焊接或胶粘的方式固定在容置槽12的槽壁。
本实施例的实施过程为：当加工产品时，磁铁或电磁铁将模仁21磁吸固定。
当模仁21有外观问题或者模仁需要更换时，将两个模座10分离，然后通 过移取工具克服磁铁的吸引力取出模仁，或者给电磁铁断电，使其不具有磁场，从而没有吸引力，然后通过移取工具移取模仁21。
上述模具100中的模仁件20具有铁磁性，磁吸件30具有磁矩，可在其周边产生磁场，吸附模仁件20，使得模仁件20固定在容置槽12内，当模仁21有外观问题或者需要更换时，只要通过移取工具克服磁吸件30的吸引力移取单个模仁21即可，模仁21的拆卸和装配均较为方便，可以大量节约时间，减少模仁损伤几率。
请参见图7，本申请的的第二实施例提出了一种模具100，第二实施例中的模具100与第一实施例中的模具100的结构大致相同，不同之处在于：
磁吸件30具有一收容腔31，模仁件20的靠近所述容置槽12的槽底的一端插装于所述磁吸件30的收容腔31内。在本实施例中，模仁21的部分和调节件22插装于所述磁吸件30的收容腔31内。可以理解地，在其他的实施例中，调节件22插装于所述磁吸件30的收容腔31内，模仁21的部分不插装于所述磁吸件30的收容腔31内。
其中，容置槽12的槽壁开设有固定槽121，所述磁吸件30至少部分收容于固定槽121内，固定槽121可收容磁吸件30，且可防止其沿着容置槽12的轴线方向运动。
如此，在模仁21插装在收容腔31内后，收容腔31可限制模仁21的摆动，且磁吸件30的靠近容置槽12的轴线的一侧可吸附模仁21，将模仁21定位于容置槽12内的准确位置，防止其在容置槽12内晃动。
本申请的的第三实施例提出了一种模具100，第三实施例中的模具100与第二实施例中的模具100的结构及说明书附图大致相同，不同之处在于：
磁吸件30为多个，且围绕所述容置槽12的轴线设置，所述收容腔31由多个所述磁吸件30围设形成。
如此，在模仁21插装在多个磁吸件30围设形成的收容腔31内后，收容腔31可限制模仁21的摆动，且磁吸件30的靠近容置槽12的轴线的一侧可吸附模仁21，将模仁21定位于容置槽12内的准确位置，防止其在容置槽12内晃动，并且，在其中一个磁吸件30损坏时只需更换此磁吸件30，减少了更换成本。
请参见图8，本申请的的第四实施例提出了一种模具100，第四实施例中的模具100与第一实施例中的模具100的结构大致相同，不同之处在于：
第三实施例中未设置调节件22和紧固件40，磁吸件30通过焊接或胶粘等固定连接方式固定于容置槽12的槽底，模仁21的靠近容置槽12的槽底的一端直接被磁吸在磁吸件30。
请参见图9，本申请的的第五实施例提出了一种模具100，第五实施例中的模具100与第二实施例中的模具100的结构大致相同，不同之处在于：
第五实施例中未设置调节件22和紧固件40，磁吸件30通过焊接或胶粘等固定连接方式固定于收容于容置槽12侧壁的固定槽121内，模仁21的靠近容置槽12的槽底的一端直接插装于磁吸件30的收容腔31内，且被磁吸件30吸附固定。
本申请的实施例提出了一种模具100中的模仁21的装卸方法，包括以下步骤：
沿模仁21背离磁吸件30的方向将模仁21取出或装设于模座10的容置槽12内。
上述方法在当模仁21有外观问题或者需要更换时，只要通过移取工具沿模仁21背离磁吸件30的方向克服磁吸件的吸引力移取单个模仁21即可，不需要拆卸整套模具，模仁21的拆卸和装配均较为方便，可以大量节约时间，减少模仁21损伤几率。
对于本领域技术人员而言，显然本申请不限于上述示范性实施例的细节，而且在不背离本申请的精神或基本特征的情况下，能够以其他的具体形式实现本申请。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本申请的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化涵括在本申请内。
最后应说明的是，以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或等同替换，而不脱离本申请技术方案的精神和范围。
