Description
技术领域
本发明专利涉及一种锥齿轮注射模具，属于注射成型模具，主要用于热塑性塑料注射成型小型锥齿轮用。
背景技术
塑料锥齿轮已广泛应用于微型电机、电子产品、汽车配件、家用电器、办公用品、玩具等各种行业，热塑性塑料锥齿轮主要采用注射成型，一般采用点浇口、三板式模具，冷凝料常用手动取出，生产效率低，甚至出现卡死，给生产带来一定的困难。
发明内容
为了更好的解决以上出现的问题，发明一种带有弹簧+推块+定距拉杆机构的注射模具，能自动实现顶出冷凝料。本发明专利提供一种结构简单、易于制造、操作方便的模具。
本发明专利的技术方案是：一种锥齿轮注射模具，包括定模与动模，定模由定模座板、流道板、定模板、凹模、推块、定距拉杆一、弹簧一、定距拉杆二、弹簧二、导套构成，导套、凹模置于定模板与流道板之间，两板用螺钉联结，定距拉杆一右端与定模座板过盈配合，弹簧一置于定模板、流道板及定模座板中，推块置于流道板上并可活动，弹簧二在定距拉杆二上，定距拉杆二右端有螺纹用于连接推块，定距拉杆二贯穿于定模板与流道板；动模由动模板、复位杆、复位杆固定板、推板、型芯固定板、垫块、型芯、推管、动模座板、导柱构成，推管、复位杆安装于复位杆固定板上，推板与复位杆固定板用螺钉联结，型芯安装于型芯固定板上，型芯固定板与动模座板用螺钉联结，型芯贯穿于推板、复位杆固定板、动模板，导柱安装于动模板上，动模座板、垫块及动模板用螺钉联结。
所述模具中的凹模是回转体，其右端带定位的轴肩。
本模具结构简单，易于制造，使用方便，能实现自动顶出冷凝料，提高生产效率。

图中3.导柱，4.导套，5.定距拉杆一，6.弹簧一，7.推块，8.定距拉杆二，9.弹簧二，10.定模座板，11.流道板，12.定模板，13.凹模，14.锥齿轮，15.动模板，16.复位杆，17.复位杆固定板，18.推板，19.型芯固定板，20.垫块，21.动模座板，22.型芯，23.推管。
具体实施方式
参考附图1，本发明锥齿轮注射模具，包括定模与动模，定模由定模座板10、流道板11、定模板12、凹模13、推块7、定距拉杆一5、弹簧一6、定距拉杆二8、弹簧二9、导套4构成，导套4、凹模13置于定模板12与流道板11之间，两板用螺钉联结，定距拉杆一5右端与定模座板10过盈配合，弹簧一6置于定模板12、流道板11及定模座板10中，推块7置于流道板11上并可活动，弹簧二9在定距拉杆二8上，定距拉杆二8右端有螺纹用于连接推块7，定距拉杆二8贯穿于定模板12与流道板11；动模由动模板15、复位杆16、复位杆固定板17、推板18、型芯固定板19、垫块20、型芯22、推管23、动模座板21、导柱3构成，推管23、复位杆16安装于复位杆固定板17上，推板18与复位杆固定板17用螺钉联结，型芯22安装于型芯固定板19上，型芯固定板19与动模座板21用螺钉联结，型芯22贯穿于推板18、复位杆固定板17、动模板15，导柱3安装于动模板15上，动模座板21、垫块20及动模板15用螺钉联结。
所述模具中的凹模13是回转体，其右端带定位的轴肩。
所述的模具，开模时，弹簧一6使模具沿I分型面分开，定距拉杆二8从浇口套中拉出主流道凝料，当定模板12受定距拉杆一5限位后，II分型面开始分型，产品随动模移动，故而点浇口被拉断，弹簧二9推动推块7使流道凝料从流道板11和定距拉杆二8上脱出。最后，在注射机的顶杆作用下，带动推板18推动推管3推落制品。合模时，复位杆16带动推管23复位。
