具体实施方式detailed description
下面结合附图及实施例对本发明作进一步描述：The present invention is further described below in conjunction with the accompanying drawings and embodiments:
如图1所示的一种锁模机构，包括左模壳1、与左模壳1通过转轴3相转动连接的右模壳2，锁模机构具有开模状态和合模状态，锁模机构还包括处于合模状态时用于将左模壳1、右模壳2锁定的锁定机构。A clamping mechanism as shown in FIG. 1 includes a left mold shell 1 and a right mold shell 2 rotatably connected to the left mold shell 1 through a rotating shaft 3, and the mold clamping mechanism has a mold opening state and a mold clamping state, and the mold clamping mechanism further A locking mechanism for locking the left mold case 1 and the right mold case 2 when in the mold clamping state is included.
如图2和3所示：当处于合模状态时，左模壳1、右模壳2通过锁定机构将左模壳1、右模壳2锁定，且左模壳1、右模壳2之间围成型腔4；如图5和6所示，当处于开模状态时，左模壳1、右模壳2之间能够通过转轴3进行转动。As shown in FIGS. 2 and 3, when in the mold clamping state, the left mold shell 1 and the right mold shell 2 lock the left mold shell 1 and the right mold shell 2 by a locking mechanism, and the left mold shell 1 and the right mold shell 2 The circumference molding cavity 4; as shown in FIGS. 5 and 6, when in the mold opening state, the left mold shell 1 and the right mold shell 2 can be rotated by the rotation shaft 3.
在本实施例中，如附图1、2、4、7所示，左模壳1上设置有三个左连接凸台5，紧邻的两个左连接凸台5之间形成缺口8。右模壳2上设置有与所述的左连接凸台5相上下交错设置的右连接凸台7，具体而言，右模壳2上设置有三个右连接凸台7，当处于合模状态时，其中两个右连接凸台7***至所述的缺口8内，位于最下方的右连接凸台7位于紧邻其的左连接凸台5的下方。当然，左模壳1可以仅具有一个左连接凸台5，此时，右模壳2也可以仅具有一个右连接凸台7。此外，左模壳1也可以具有四个左连接凸台5，此时，右模壳2也可以具有四个右连接凸台7。因而，本发明的保护不应局限于左连接凸台5和右连接凸台7的数量，在本实施例中以左连接凸台5、右连接凸台7设置3个为例，设置两个、四个或更多结构相同，在此不再赘述。In the present embodiment, as shown in FIGS. 1, 2, 4, and 7, the left mold case 1 is provided with three left connection bosses 5, and the immediately adjacent two left connection bosses 5 form a notch 8. The right mold shell 2 is provided with a right connecting boss 7 which is arranged in a staggered manner with the left connecting boss 5, and specifically, the right mold shell 2 is provided with three right connecting bosses 7 when in the mold clamping state. At this time, two of the right connecting bosses 7 are inserted into the notch 8 and the lowermost right connecting boss 7 is located below the left connecting boss 5 adjacent thereto. Of course, the left mold shell 1 may have only one left joint boss 5, and in this case, the right mold shell 2 may have only one right joint boss 7. Furthermore, the left formwork 1 can also have four left connecting bosses 5, in which case the right formwork 2 can also have four right connecting bosses 7. Therefore, the protection of the present invention should not be limited to the number of the left connecting boss 5 and the right connecting boss 7. In the embodiment, three of the left connecting boss 5 and the right connecting boss 7 are provided as an example, and two are provided. Four or more structures are the same and will not be described here.
在本实施例中，三个左连接凸台5上分别开设有三个销孔6。这三个销孔6的轴线必须要相平行。In this embodiment, three left connecting bosses 5 are respectively provided with three pin holes 6. The axes of the three pin holes 6 must be parallel.
锁定机构包括可在右模壳2内滑动的连接轴9、与连接轴9固定连接的连杆12以及与连杆12固定连接的销轴10。销轴10、连杆12的数量与右连接凸台7的数量相同，也是三个。右连接凸台7上开设有分别供三个连杆12与销轴10滑动的三个槽孔14。在连接轴9相对右模壳2滑动过程中，三个销轴10能够伸缩地设置在三个右连接凸台7内。三个销轴的轴线、三个销孔6的轴线以及连接轴的滑动方向相平行。当然更优选地，为了保持锁定的稳定，这三个销孔6的轴线相重合，三个销轴10的轴线也相重合。The locking mechanism includes a connecting shaft 9 slidable within the right mold case 2, a link 12 fixedly coupled to the connecting shaft 9, and a pin 10 fixedly coupled to the link 12. The number of the pin 10 and the connecting rod 12 is the same as the number of the right connecting bosses 7, and is also three. Three slots 14 for sliding the three links 12 and the pin 10, respectively, are opened on the right connecting boss 7. During the sliding of the connecting shaft 9 with respect to the right mold shell 2, the three pins 10 are telescopically disposed in the three right connecting bosses 7. The axes of the three pins, the axes of the three pin holes 6, and the sliding direction of the connecting shaft are parallel. More preferably, in order to maintain the stability of the lock, the axes of the three pin holes 6 coincide, and the axes of the three pin shafts 10 also coincide.
当处于开模状态时，三个销轴10分别位于与其相对应的三个槽孔14内；当处于合模状态时，三个销轴10相对右连接凸台7滑动以露出三个槽孔14，并***与其相对应的销孔6。When in the mold opening state, the three pins 10 are respectively located in the corresponding three slots 14; when in the mold clamping state, the three pins 10 slide relative to the right connecting boss 7 to expose three slots. 14, and insert a pin hole 6 corresponding thereto.
在本实施例中，连接轴9的下端部连接有驱动块11。驱动块11位于最下方的右连接凸台7外部。驱动块11还与位于最下方的销轴10相固定连接。操作人员可通过对驱动块11的操作，驱使销轴10以及连接轴9相对右模壳2滑动。驱动块11可以与连接杆12相同，也可以为了方便操作，其体积大于连接杆12的连接件。In the present embodiment, the drive block 11 is connected to the lower end portion of the connecting shaft 9. The drive block 11 is located outside the lowermost right connection boss 7. The drive block 11 is also fixedly connected to the pin 10 located at the bottom. The operator can drive the pin 10 and the connecting shaft 9 to slide relative to the right mold case 2 by the operation of the drive block 11. The drive block 11 can be identical to the connecting rod 12, or it can be larger in volume than the connecting piece of the connecting rod 12 for convenience of operation.
优选地，当处于开模状态时，部分销轴10、连杆12露出右连接凸台7，因此，左连接凸台5上对应销轴10、连杆12露出右连接凸台7的位置开设有避让凹槽13，这样，在合模状态时，销轴10、连杆12不会对左连接凸台5产生干涉。并且采用此种结构，避让凹槽13能够对该锁模机构的合模位置进行定位，更优选地，当销轴10与避让凹槽13相抵时，左模壳1不能再相对右模壳2进行合模方向的旋转，且此时销轴10位于其对应销孔6的正下方。Preferably, when in the mold opening state, the partial pin 10 and the connecting rod 12 expose the right connecting boss 7, so that the position of the corresponding connecting pin 10 on the left connecting boss 5 and the connecting rod 12 exposing the right connecting boss 7 are opened. The recessed groove 13 is provided so that the pin 10 and the link 12 do not interfere with the left connecting boss 5 in the mold clamping state. And with such a structure, the avoidance groove 13 can position the clamping position of the clamping mechanism, and more preferably, when the pin 10 abuts against the escape groove 13, the left mold shell 1 can no longer be opposite to the right mold shell 2 The rotation in the mold clamping direction is performed, and at this time, the pin 10 is located directly below the corresponding pin hole 6.
以下具体阐述下本实施例的工作状态：The working state of the present embodiment is specifically explained below:
当需要合模时，通过转轴3，使右模壳2的右连接凸台7***至左模壳1的左连接凸台5的缺口8内，向上拉动驱动块11，使驱动块11驱动连接轴9传动销轴10伸出右连接凸台7的槽孔14并且***左连接凸台5的销孔6内，左模壳1和右模壳2完成锁定，如图7所示，此时，在两者完成合模时，锁定机构的销轴10从外部无法看到，更无法触碰，具有一定的安全型。When the mold clamping is required, the right connecting boss 7 of the right mold shell 2 is inserted into the notch 8 of the left connecting boss 5 of the left mold shell 1 through the rotating shaft 3, and the driving block 11 is pulled upward to drive the driving block 11 to be connected. The shaft 9 drive pin 10 extends out of the slot 14 of the right connecting boss 7 and is inserted into the pin hole 6 of the left connecting boss 5, and the left mold shell 1 and the right mold shell 2 are locked, as shown in FIG. When the clamping is completed, the pin 10 of the locking mechanism is invisible from the outside, and is incapable of being touched, and has a certain safety type.
