In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. When the injection molding side wall has plastic parts such as holes, pits, and bosses, the parts formed on the mold must be made into laterally movable parts, called movable cores. The active core must be pulled out before the plastic part is demoulded, otherwise it will not be possible to demould. The entire mechanism that drives the movable core to move sideways is called the lateral parting and core-pulling mechanism, referred to as the side core-pulling mechanism. The traditional side core-pulling mold has complex structure, cumbersome operation and poor core-pulling effect.

具体实施方式detailed description
现在结合附图对本实用新型作进一步的说明。这些附图均为简化的示意图仅以示意方式说明本实用新型的基本结构，因此其仅显示与本实用新型有关的构成。The utility model is described further in conjunction with accompanying drawing now. These drawings are simplified schematic diagrams only to illustrate the basic structure of the utility model in a schematic way, so they only show the configurations related to the utility model.
如图1所示的新型齿轮齿条型侧抽芯注塑模具，包括定模组件和动模组件，定模组件包括定模型腔板9，动模组件包括动模板13和动模型腔板15，动模板13和动模型腔板15之间设有固定连接的传动齿条固定板1和传动齿条推板14，传动齿条固定板1上垂直安装有传动齿条12；动模型腔板15中心设有塑件要求的型芯6和齿条型芯8，齿条型芯8连接有驱动组件，驱动组件包括安装在动模型腔板15上的齿轮11，齿条型芯8和传动齿条12位于齿轮11两侧且均与齿轮11啮合；传动齿条固定板1和动模型腔板15之间的空腔内设有塑件推出组件。The new rack-and-pinion side core-pulling injection mold shown in Figure 1 includes a fixed mold assembly and a movable mold assembly, the fixed mold assembly includes a fixed mold cavity plate 9, and the movable mold assembly includes a movable template 13 and a movable mold Cavity plate 15, be provided with fixedly connected drive rack fixed plate 1 and drive rack push plate 14 between movable template 13 and movable model cavity plate 15, drive rack 12 is vertically installed on the drive rack fixed plate 1; The center of the model cavity plate 15 is provided with a core 6 and a rack core 8 required by the plastic part. The rack core 8 is connected with a drive assembly, and the drive assembly includes a gear 11 installed on the movable model cavity plate 15. The rack core 8 and the transmission rack 12 are located on both sides of the gear 11 and are all meshed with the gear 11; the cavity between the transmission rack fixed plate 1 and the moving mold cavity plate 15 is provided with a plastic part ejection assembly.
塑件推出组件包括固定连接的推板2和推杆固定座3，推杆固定座3上垂直设有推杆4，推杆4穿过型芯6与塑件相接触；动模型腔板15上安装有弹簧销5，齿条型芯8上设有半圆槽7；定模型腔板9上安装有使传动齿条12复位的复位杆10。The plastic part ejection assembly includes a fixedly connected push plate 2 and a push rod holder 3, a push rod 4 is vertically arranged on the push rod holder 3, and the push rod 4 passes through the core 6 and contacts the plastic part; the movable mold cavity plate 15 A spring pin 5 is installed on it, and a semicircular groove 7 is provided on the rack core 8 ;
开模时，动模部分向左移动，塑件包在齿条型芯8上从定模型腔板9中脱出后随动模部分一起向左移动，主流道凝料在拉料杆作用下与塑件连在一起向左移动。当传动齿条推板14与注射机的顶杆接触时，传动齿条12静止不动，动模部分继续后退，传动齿条12带动齿轮11作逆时针方向的转动，从而使与齿轮11啮合的齿条型芯8作斜侧方向抽芯。当抽芯完毕，传动齿条固定板1与推板2接触，并且推动推板2使推杆4将塑件推出。合模时，复位杆8使传动齿条12复位。复位杆8在注射时还起到楔紧块的作用。When the mold is opened, the movable mold part moves to the left, and the plastic part wraps on the rack core 8 and escapes from the fixed mold cavity plate 9, and then moves to the left together with the movable mold part. The plastic parts move to the left together. When the drive rack push plate 14 is in contact with the ejector rod of the injection machine, the drive rack 12 remains still, the movable mold part continues to retreat, and the drive rack 12 drives the gear 11 to rotate counterclockwise, so that the gear 11 meshes The rack core 8 is used for oblique side direction core pulling. When the core pulling is completed, the drive rack fixed plate 1 contacts the push plate 2, and pushes the push plate 2 to push the push rod 4 out of the plastic part. During mould-closing, the reset rod 8 resets the transmission rack 12. Reset lever 8 also plays the role of wedge block when injecting.
这种新型齿轮齿条型侧抽芯注塑模具结构简单，设计合理，操作方便，通过齿条型芯8、齿轮11和传动齿条12的相互配合，抽芯推出效果好，提高了产品质量，加快了生产速度。This new rack-and-pinion side core-pulling injection mold has a simple structure, reasonable design, and convenient operation. Through the mutual cooperation of the rack core 8, the gear 11 and the transmission rack 12, the core-pulling effect is good, and the product quality is improved. Speed up production.
