Checklist for mold GA Drawings

 It is more effective to use a 2-tier structure for the check list of mold drawings.


First, write a checklist that is checked separately by the designer and by a third party. The purpose of this checklist is to identify, from a third-party neutral perspective, whether there are serious misunderstandings about important items.

Second, write a "self-checklist" based on the designer's own detailed thinking path.

The purpose of this checklist is to find human error in detailed design matters.


The following is an example of a "check list" that was checked by the designer himself and by a third party.


(1) Is the front and back of the cavity-core correct?


(2) Is the number of cavities consistent?


(3) Does the parting surface meet the specification requirements?


(4) Does the gate position meet the specification requirements?


(5) Is the cost structure of the formed product satisfactory?


(6) In terms of production performance, does it have a satisfactory production capacity?


(7) Can the mold be installed on the injection molding machine used?


(8) Is it 100% no problem to release from the fixed side?


(9) Is it 100% OK to eject from the active side?


(10) Is it 100% no problem for the molded product to be demoulded from the side core-pulling slider?


(11) Is the runner layout appropriate?


(12) Is the direction of the center offset wrong?


(13) Is the preset forming shrinkage rate appropriate?


(14) Is the division of inserts appropriate?


(15) Is the disassembly frequency of the mold consistent with the maintenance structure?


(16) Is there any part where interference or collision will occur between parts?


(17) Does it meet special specification requirements?


(18) Is the mold temperature appropriate?


(19) Is the structure able to meet the delivery date requirements?


(20) Have you predicted the problem of poor molding and taken countermeasures accordingly?

Molding Conditions of Injection Molding Machine (Part 2)

 1. Filling pressure In injection molding conditions, filling pressure refers to the pressure to fill the resin into the mold, also known as primary pressure. The unit is MPa or kgf/cm2. That is the unit of pressure. There are also some injection molding machines that set the maximum injection pressure to 100%, and then adjust the injection molding conditions by changing the percentage. (Example: 35%) If the filling pressure is too low, poor filling (underfill) will occur. If the filling pressure is too high, the parting surface may be momentarily opened by the pressure, and burrs may appear around the molded product. Sometimes poor release occurs. 2. Injection speed Injection speed refers to the speed at which molten plastic fills the mold. The unit is mm/s. When considering injection volume per unit of time, it may be stated as "injection rate", in which case the unit is cm3/s. If the injection speed is too slow, filling defects may occur; if the injection speed is too fast...

How to choose the original positioning parts of injection mold custom processing workpiece?

 1. Injection mold custom processing workpiece to plane positioning According to the number of degrees of freedom restricted by the plane, it can be divided into three types: The main support surface restricts the positioning plane of the three degrees of freedom of the workpiece, and is often used for the positioning surface of the workpiece with relatively high precision. The guide support surface is a positioning plane that limits the two degrees of freedom of the workpiece, and is often made into a narrow and long surface. The thrust support surface is a plane that limits one degree of freedom. In order to ensure accurate positioning, the area of the plane is often made as small as possible. 2. Injection mold custom processing workpiece is positioned with a round hole Long pins limit 4 degrees of freedom; short pins limit 2 degrees of freedom. 3. Injection mold custom processing workpiece outside cylindrical surface positioning The positioning datum is the centerline of the out...

2K tooling on Injection molding

图片
 Injection molding is a process that was developed based on microfabrication techniques such as LIGA, but there are of course many other methods. The LIGA process is to first produce a model required for injection molding, which is commonly known as "mold", and then pour liquid plastic into the mold, and finally separate it to form the final required product. For example, some Automotive parts have too many products. Injection mold processing is to add plastic to the mold first, and then the mold is continuously rotated along two vertical axes and heated. The plastic in the mold is gradually and evenly coated and melted and adhered to the entire cavity of the mold cavity under the action of gravity and heat energy. On the surface, it is formed into the desired shape, and it is made by cooling and setting.
