1. 模具及其零件与塑件图纸的关系,模具及模具零件的材质、硬度、尺寸精度,结构等是否符合塑件图纸的要求。
1. the relationship between the mold and its parts and the drawings of the plastic parts. The material, hardness, dimensional accuracy and structure of the die and die parts are in conformity with the requirements of the drawings.
2. 塑料制件方面
2. parts of plastic parts
塑料料流的流动、缩孔、熔接痕、裂口,脱模斜度等是否影响塑料制件的使用性能、尺寸精度、表面质量等方面的要求。图案设计有无不足,加工是否简单,成型材料的收缩率选用是否正确。
Whether the flow of plastic flow, shrinkage hole, weld mark, crack, stripping angle and so on affect the use performance, size accuracy and surface quality of plastic parts. Whether there is any shortage in pattern design, whether machining is simple, and whether the shrinkage rate of molding material is correct.
3. 成型设备方面
3. molding equipment
注射量、注射压力、锁模力够不够,模具的安装、塑料制件的南芯、脱模有无问题,注射机的喷嘴与哓口套是否正确地接触。
The injection amount, the injection pressure and the clamping force are not enough. There are no problems with the installation of the mold, the South core and the mold release of the plastic parts.
4. 模具结构方面
4. aspects of die structure
分型面位置及精加工精度是否满足需要,会不会发生溢料,开模后是否能保证塑料制件留在有顶出装置的模具一边。
Whether the position of the parting surface and the precision of precision machining meet the needs will not occur, and the plastic parts can be kept on the side of the mold with the ejector device after the die opening.
脱模方式是否正确,推广杆、推管的大小、位置、数量是否合适,推板会不会被型芯卡住,会不会造成擦伤成型零件。
Whether the demoulding mode is correct, the size, position and quantity of the extension rod and tubing are suitable, and the push board will not be stuck by the core, and will not cause the scraping parts.
模具温度调节方面。加热器的功率、数量;冷却介质的流动线路位置、大小、数量是否合适。
Mould temperature regulation. The power and quantity of the heater are suitable for the location, size and quantity of the cooling medium.
处理塑料制件制侧凹的方法,脱侧凹的机构是否恰当,例如斜导柱抽芯机构中的滑块与推杆是否相互干扰。
To deal with the side concave method of plastic parts, whether the mechanism of the side concave is appropriate, for example, whether the slider and push rod of the inclined guide core pulling mechanism interfere with each other.
浇注、排气系统的位置,大小是否恰当。
The location and size of the casting and exhaust system are appropriate.
设计图纸
Design drawings
装配图上各模具零件安置部位是否恰当,表示得是否清楚,有无遗漏
Is the location of each part of the mould assembly appropriate, indicating whether it is clear and omission?
零件图上的零件编号、名称,制作数量、零件内制还是外购的,是标准件还是非标准件,零件配合处理精度、成型塑料制件高精度尺寸处的修正加工及余量,模具零件的材料、热处理、表面处理、表面精加工程度是否标记、叙述清楚。
The number and name of parts, the name of the parts, the quantity, the internal system or the purchase, is the standard or non standard parts, the accuracy of the parts and the accuracy of the parts, the corrected processing and remainder of the high precision size of the molded parts, and the marking and narration of the material, heat treatment, surface treatment and the degree of surface finishing of the mold parts. It is clear.
5. 零件主要零件、成型零件工作尺寸及配合尺寸。尺寸数字应正确无误,不要使生产者换算。
5. working parts and main parts of the parts. The size number should be correct and do not convert the producer.
6. 检查全部零件图及总装图的视图位置,投影是否正确,画法是否符合制图国标,有无遗漏尺寸。
6. check the location of all parts and assembly drawings, whether the projection is correct, whether the drawing is in line with the national standard for drawing, and whether there is a missing size.
7. 校核加工性能:(所有零件的几何结构、视图画法、尺寸标等是否有利于加工)
7. check processing performance: (all parts geometric structure, view drawing, size and so on is conducive to processing).
8. 复算辅助工具的主要工作尺寸
The main working dimensions of the 8. compound tool
专业校对原则上按设计者自我校对项目进行;但是要侧重于结构原理、工艺性能及操作安全方面。
Professional proofreading is carried out in accordance with the designer's self proofreading project, but it should be focused on structural principles, process performance and operational safety.
9. 编写制造工艺卡片
9. write the manufacturing process card
编写制造工艺卡片,并且为加工制造做好准备。在模具零件的制造过程中要加强检验,把检验的重点放在尺寸精度上。模具组装完成后,由检验员根据模具检验表进行检验,主要的是检验模具零件的性能情况是否良好,只有这样才能保证模具的制造质量。
Compile manufacturing process cards and prepare for manufacturing. In the manufacturing process of mold parts, inspection should be strengthened and emphasis should be placed on dimensional accuracy. After the mold assembly is completed, the inspector is inspected according to the mold inspection table. The main thing is to check the performance of the die parts well. Only in this way can the quality of the mould be ensured. |
