1. For mold bases smaller than 2020, pry pits need to be made between plates A and B; for mold bases larger than 2020, pry pits need to be made between all templates including the ejector plates.
2
The guide posts and bushings of the mold base must be processed with exhaust grooves to prevent the guide posts and bushings from being strained.
3
There must be no sharp corners on the mold and must be chamfered. Except where specified
4
Internal molds and mold parts must not be welded without consent.
5
Exhaust slots must be opened at appropriate locations around the mold product. Please refer to the mold design manual for the exhaust slot specifications.
6
Try to avoid using a grinder to polish the mold. If you must use a grinder to polish the mold, you must use a whetstone to smooth it (especially the parting surface)
7
The surface treatment of the inner mold glue surface must be carried out in accordance with the BOM list or other officially notified technical requirements. The processing texture on the non-glue surface (wire cutting, milling machine, CNC gong machine, spark machine) should also be polished with a whetstone.
8
All internal mold materials and mold base grade requirements must be purchased based on the order or the technical requirements formally confirmed during the design review process. Material certification must be provided, and if it is a hard mold, a heat treatment report must be provided. All relevant certificates.
9
All the front and rear inner molds, inserts, row positions, inclined tops, straight tops (push blocks), shovel chickens, etc. of all molds need to be processed with a waist-round pit on the bottom or side, and the material name and hardness are engraved.
10
Important easy-to-wear parts such as the row position, push block, shovel chicken, and mouthpiece must be nitrided and hardened.
11
The rows must be positioned. Positioning methods include slingshots, wave beads, HASCO (DME) standard positioning clips, etc. The specific requirements need to be according to the requirements of each project. The row position needs to have battens and wear-resistant plates. Layers and wear-resistant plates must be made of wear-resistant hard materials, and an oil groove needs to be added.
12
The inclined guide pillars must be pressed tightly and cannot rotate or loosen. The tail of the inclined guide column must be processed into a hemispherical or truncated cone shape to ensure normal movement of the row. If there are two or more inclined guide posts in the same row, the length, size and inclination of the inclined guide posts must be the same.
13
Sloping-top seats must be made of wear-resistant hard material. The inclined roof must be processed with an oil groove. The inclined roof base is generally hardened with 2510 or CR12 to HRC40-45 degrees. Because the inclined roof base is subject to impact load, it cannot be too hard or it will break. C-angles must be chamfered at all right-angled positions. . A sloped roof guide plate (bronze) is required. No welding allowed.
14
The flow channel and glue feeding position need to be glossy #400-600.
15
The ejector pin, cylinder, ejector pin, inclined ejector and ejector plate should be engraved with corresponding identification codes to facilitate installation. If the position of the ejector pin on the product is not horizontal, the ejector pin seat needs to be made into a "D" shape or positioned using an anti-rotation pin key.
16
The ejector pin adopts HASCO or DME standards. Which one to choose depends on the BOM table or other officially notified mold technical requirements.
17
When processing the groove of the water-carrying apron ("O" ring), a gap of 0.25mm needs to be reserved on one side. Generally, the apron needs to be pre-pressed by 0.5-0.8mm. If you do not pay attention to this, the apron will be easily crushed and damaged. causing water leakage.
18
The mouth of the mouthpiece needs to be nitrided and needs to be anti-resale. The radius of the spout must comply with the drawing requirements. The nozzle is not nitrided and may have been damaged before the mold was moved.
19
Conventional structure molds must be equipped with support heads, and both end surfaces need to be ground flat. The small mold is preloaded by 0.1mm, and the large mold is preloaded by 0.1mm-0.15mm.
20
The diameter of the positioning ring must comply with the drawing, and the form and position of the top rod joint must comply with the drawing.
twenty one
Please refer to the BOM list or confirmed mold drawing for the specifications of the faucet. The countersunk hole of the faucet must be processed and installed according to the mold drawing. Drilling holes must not be drilled off-center, and sharp corners must be chamfered.
twenty two
Water transport must be marked in1, out1, in2, out2………….
twenty three
All markings printed on the mold must be neat, straight and not twisted.
twenty four
The mold needs to be equipped with side locks (straight body locks) on four sides. If the side lock cannot be installed, a taper lock, or cone lock, needs to be installed. The taper lock should be installed horizontally.
25
All screws and mold accessories must be standard parts, and the screw heads cannot be sawed off. The effective locking length of the screw must be sufficient, normally 1.5 or 2.
26
Hot nozzle wire troughs must be rounded to avoid scratching the wires.
27
Install the hot nozzle ID card on the side of the mold panel.
28
Mold handover and acceptance: You need to cooperate with the mold engineer to accept the mold according to the "Mold Checklist" before packaging and mold removal.
29
Before moving the mold, the water pressure needs to be tested (above 100pa). After the water is accepted, the water needs to be blown clean with an air gun.
30
During the manufacturing process, the outer surface of the mold base needs to be maintained to prevent rust and scratches. Before moving the mold for packaging, the inner mold needs to be sprayed with white/or colorless rust inhibitor, and all mold surfaces must be cleaned and then greased with butter.
