Manufacturing specifications for plastic molds

First, confirm the picture:

A. Water Road:

1. Male and female models: According to the shape of the finished product, the path and quantity of the water circulation, the waterway of the male and female molds must cooperate with each other.

2. Stripper plate x 2 cycle.

3. The counterbore is required at the above water hole joint, and the counterbore size is $35*L25mm.

4. The hydrant of the mold must be IN, OUT and numbered.

5. A copper hydrant is required. A01&A07 is a plastic hydrant. The size of the A09 copper hydrant is 1/4" PT.

6. Side water stopcock, 2PCS water stop plug or 1PCS water stop plug + copper block.

7. If there is a water spray hole, use a copper plate as a partition.

B. Ditch: According to the balance of the finished product, the path, shape, size, etc. of the groove are designed.

C. Advance point: According to the appearance shape and the key point of the finished product, the type of the entry point is determined, which is a needle point, a side needle point, a side edge shape, a cone shape, and the like.

D. Ejection method:

1. The PIN is ejected and the DME specification (depending on the customer) is required.

2. When the ejector finished product has a shape, it needs to be oriented.

3. Eject the ring (pay special attention to the draft angle of the water ring) or top out the block.

E. Positioning block X 4: 360 degree/4 in the male and female templates, and the positioning block with long square shape to increase the precision of the reference surface (Material: SKD-61) China Plastic Mould Net

F. Molding method:

1. Lock the screws of the male and female molds, the more the design is better, and the average distribution is required to make the contact surface of the mold core and the mold base more close.

When locking the screw, it needs to be locked and locked, and the torque is the same.

2. Both male and female molds must have a positioning tip that snaps into the mold base.

3. All inserts must be positioned when they are round, and can only be assembled in one direction to avoid wrong orientation during assembly.

The G.4 branch column needs to have 1pcs for eccentricity, and the X and Y axes are each 10mm.

H. The screw holes and screws of the mold shall be the metric specifications of DME.

I. The return pin seal should have a top resistant plate and the material is TDAC+nitriding.

J. If there are oblique pins and sliders, wear plates should be added on all three sides, and there must be oil grooves (material: TDAC + nitriding treatment).

K, need to install counters, INSERT type (A09 customers only need).

L. The length, width, height, positioning ring and KO hole of the mold need to match the size of the customer's machine.

M. If it is a three-plate mode, A09 is an external switch, and A is an internal switch.

N, CHECK between the master and the stripper, is the separation distance sufficient, the robot takes out the material, considering the length of the LGP & the machine

Maximum journey.

O. An indication arrow for electrical discharge machining is required on the mold.

P.Name Plate, arrow, clamp, Part No., date stamp, hole number, recycling chapter, counter, etc., should be marked on the structure drawing.

Q. When the mold is shipped, the arrow needs to be sprayed with yellow paint, and the lock module needs to be sprayed with red paint.

R. When the mold needs to be forced back, it is necessary to stick the forced return plate under the arrow of the die.

S. All slider mechanisms need to be spring loaded.

T. All BUSH needs to add a locating pin.

U. It is necessary to pay attention to the problem of shrinkage, especially the size of the assembly.

V. The specification of the layers and lines of the mold structure diagram:

1. Center line ----------- Pink.

2. Ditch ----------- Yellow.

3. Waterway ----------- Light orange.

4. Dimensional line, explanatory text & material list ----------- Basket color.

5. Mold structure:

a. Appearance ---------- Black.

b. Mechanism (slider, skew pin, rolling cylinder, etc.) ----------- Water basket color.

c. Parts of the spare parts (screws, shafts, thimbles, etc.) ---------- Violet basket color.

6. Finished Products & Hongsheng Logo ---------- Green.

W. Manufacturers must provide mold structure drawings and detailed parts drawings.

X. It is necessary to know who made the drawing, mold base machining, NC machining, grinding processing, etc.
