背景技术Background technique
在模具领域中，有些塑料制品的内侧需要设计凸起或凹陷，这些凸起或凹陷位置在设计注塑模具的时候，不能直接顶出，通常设计斜顶机构顶出产品。斜顶机构通常设置在模具的后模位置，装在顶针板上，顶针板动作时，斜顶也跟着动作。目前的模具斜顶结构中，斜顶头部较大的都采用组合式结构，有利加工。组合式的斜顶头部和斜顶杆连接基本采用销钉定位，螺钉锁紧。在安装、维修过程中，拆卸不方便，另外，斜顶杆润滑效果不好，斜顶杆容易磨损和产生变形，容易损坏斜顶，需要对其进行改进。In the field of molds, some plastic products need to be designed with protrusions or depressions on the inner side. These protrusions or depressions cannot be directly ejected when designing the injection mold. Usually, an inclined ejector mechanism is designed to eject the product. The inclined ejector mechanism is usually set at the position of the rear mold of the mold and installed on the ejector plate. When the ejector plate moves, the inclined ejector also moves accordingly. In the current structure of the inclined top of the mold, the larger head of the inclined top adopts a combined structure, which is beneficial to processing. The connection between the combined inclined jack head and the inclined jack bar is basically fixed by pins and locked by screws. In the process of installation and maintenance, it is inconvenient to disassemble. In addition, the lubrication effect of the inclined ejector rod is not good. The inclined ejector rod is easy to wear and deform, and it is easy to damage the inclined ejector. It needs to be improved.

A countersunk hole 2-1 and a lifting screw hole 2-2 are opened on one side of the wedging block 2. One side of the inclined top core head 1 There is a wedging groove matched with the wedging block 2, and the wedging block 2 is inserted into the wedging groove, and the inclined ejector rod 4 is fixed between the wedging block 2 and the inclined ejector core head 1 through the fastener 3.
如图3所示，所述的楔紧块2的上下两个面与底面的楔角均为10°。As shown in FIG. 3 , the wedge angles between the upper and lower surfaces of the wedge block 2 and the bottom surface are both 10°.
如图3所示，所述的紧固件3为螺钉。As shown in FIG. 3 , the fasteners 3 are screws.

本实用新型的工作原理如下：The working principle of the utility model is as follows:
开模时，斜顶座8向上移动，在导滑块6和保持套5的限制下，斜顶杆4在导滑块6和保持套5内沿着斜顶杆4的轴线方向斜向上滑动，斜顶杆4同时带动斜顶型芯头1和楔紧块2共同向斜向上滑动，由于斜顶杆5和竖直方向有一定夹角，所以斜顶杆4斜向上移动的距离越大，就越远离塑胶零件凹槽，从而实现侧向抽芯；合模时，斜顶座8向下复位，带动该斜顶机构共同复位。本实用新型通过紧固件3和起拔螺钉将斜顶杆4固定在楔紧块2与斜顶型芯头1之间，安装和拆卸方便，有利于斜顶机构的安装和维修；另外，导滑块6内表面设有油槽，能有效增大斜顶杆4的润滑效果，减少因摩擦积累的热量导致斜顶杆4的变形和磨损，提高了模具寿命和产品质量，实用性强。When the mold is opened, the inclined ejector seat 8 moves upwards, and under the restriction of the guide slider 6 and the retaining sleeve 5, the inclined ejector rod 4 slides obliquely upward along the axial direction of the inclined ejector rod 4 inside the guide slider 6 and the retaining sleeve 5 , the inclined ejector rod 4 simultaneously drives the inclined ejector core head 1 and the wedge block 2 to slide upwards obliquely. Since the inclined ejector rod 5 has a certain angle with the vertical direction, the greater the distance that the inclined ejector rod 4 moves obliquely upward , the farther away from the groove of the plastic part, so as to realize lateral core pulling; when the mold is closed, the inclined top seat 8 resets downward, driving the inclined top mechanism to reset together. The utility model fixes the inclined ejector rod 4 between the wedge block 2 and the inclined ejector core head 1 through the fastener 3 and the lifting screw, which is convenient for installation and disassembly, and is beneficial to the installation and maintenance of the inclined ejector mechanism; in addition, The inner surface of the guide slider 6 is provided with an oil groove, which can effectively increase the lubrication effect of the inclined ejector rod 4, reduce the deformation and wear of the inclined ejector rod 4 caused by the heat accumulated by friction, improve the life of the mold and the product quality, and has strong practicability.
