1、 内分型模结构
内分型模结构是注射模设计、制造的难点,目前国内模具企业中掌握这项技术的厂家还不是很多.在高档汽车中采用内分型模结构和相关技术的企业,国内主要以大众汽车为主.下面以形状比较复杂的保险杠为例,说明内分型模结构.内分型模采用内分型及二次推出结构,如图2所示.塑件与定模型腔的倒扣位置处有5.5mm的干涉,如采用常规斜面推出,开模时会因塑件拉环而影响精度和损坏模具.为使模具能顺利出模,斜推过程中必须让出足够空间,使塑件在局部弹性变形范围内顺利出模,因此避免斜推块与定模型腔碰撞是设计要点.解决方法：
（1） 开模时在氨气弹簧及拉模扣的作用下,定模型腔与斜推块同步动作,斜推块带动拉快一起运动,也就是开模时利用氨气弹簧推动推杆固定板和推板,保持推板与定模腔的相对位置.
（2） 利用塑件的可变形状,在开模到达预定行程时,再通过斜推块内横向的拉快将将塑件末端向内拉动,使塑件末端脱离定模型腔倒钩处.
（3） 模具开启,塑件与定模型腔分离.
（4） 继续推出,通过斜推块和限位导向的作用控制拉快向外运动,使塑件回复原来形状.

1, inside points mould structure
The structure is within parting injection die design, manufacture, and the domestic difficulty of mastering the technology in mould enterprise the manufacturer had not many. In high-end automobiles in points mould structure by the enterprise, and related technique in domestic mainly Volkswagen primarily. Here in shape more complex bumper as an example, the structure of mould in points. Parting formwork within within subtypes and second launch structure, shown in figure 2. Plastics with the model of location place have cavity upside down the interference, such as 5.5 mm with conventional cant open mold release, and will affect the TAB for plastics precision and damage the mould. To make mould can smooth the mold, oblique push process must be conceded enough space, make plastic parts within the local elastic deformation, thus eliminating the mold smoothly with fixed inclined push block cavity collisions are design key points of the model. Solution:
(1) when open mold in ammonia spring and pull mode button, under the action of fixed model cavities and oblique push block synchronous movement driven, inclined push pull fast exercise with block cavity, is also using ammonia spring push push rod fixation plate and push board, maintain push board and set the relative position of the cavity.
(2) use plastics in the variable shapes, open mold arrived at the scheduled trip, again through oblique push transverse pull fast within blocks to end plastic parts will be pulling, make plastic parts within the terminal from set model in cavity barb.
(3) mould open, plastics and fixed model cavity separation.
(4) continue to release, pushing through the block and limit the function of the guidance of control to pull fast, movement outside molded parts reply original shape.
