Precautions for the appearance of cheap molds

Precautions for the appearance of cheap molds

1: The content within the nameplate should be printed while using the mold number, mold pounds (KG), and mold size (mm). The characters are all marked with 1/8 micron code, and the characters are clear and smartly arranged.

2: The nameplate ought to be fixed on the pattern leg near the rear theme and the personal reference corner (15mm away from equally sides), set with four rivets, fixed reliably, and not easy to peel off.

3; The cooling water nozzle should use a cheap block to insert the tank nozzle, ￠10 tube, the specification can be G1/8″, G1/4″, G3/8″. In cases where there are extraordinary requirements in the contract, please follow the contract.

4: The cooling drinking water nozzle ought to extend out of the aluminum cnc parts surface, and the head of the water nozzle indented into the exterior surface should not exceed 3mm.

5: The diameter for the cooling normal water nozzle avoidance hole should be ￠25, ￠30, ￠35mm three specifications, the outer edge of the hole has a chamfer, the chamfer is greater than 1 . 5×45, as well as the chamfer is the same.

6: The a / c water nozzle must have an entry and exit recognise, the inlet water is at, the outlet water is OUT, plus the sequence number is added after IN and OUT, such as IN1 and OUT1.

7: Bench mark English personalities and numbers ought to be capitalized (5/6″), the location is 10mm directly below the tap, the handwriting is clear, beautiful, neat, and evenly spaced.

8: The inlet and outlet nozzles and the inlet and outlet nozzles should be the same as the conditioning water valve, and add G (gas) and O (oil) with a card blank character just before IN and OUT.

9: There are water nozzles to the upper and lower ends of the mould installation path, which should end up being built-in, and open the diversion groove or have a support column below it with protection.

12: The ceiling fan oil nozzle or water nozzle that cannot be built-in should be protected by a support column.

11: Machining uhmw mold bottom part will need to have a reference position symbol for each template, made a fortune English DATUM, the word height is 5/16″, the positioning is 10mm from the side, the writing is obvious, beautiful, nice, and equally spaced.

12: Each design must have a part number. The number is 10mm from the bottom directly under the reference viewpoint symbol, and certain requirements will be the identical to No . 11.

13: Mold fashion accessories should affect the lifting and storage from the mold. For example, there should be support legs to protect the important tank, drinking water nozzle, and pre-reset mechanism that problem underneath during installation.

fourteen inches: To install the support thigh, use screws to pass through the support lower-calf and fix it on the style base, or to fasten the excessively long support leg to the mildew and mold base by turning external threads.

15: Machining uhmw plastic shape ejection pit must meet the specified treatment molding machine, except for small molds, in principle, you center can’t be used for ejection (when the length or fullness of the fungal is higher than 500mm), the ejection ditch diameter ought to be larger than the top The fly fishing line is 5-10mm larger.

12: The position ring should be reliably set (usually 3 M6 or perhaps M8 hexagon socket screws), the diameter is generally ￠100 or ￠150mm, 10mm higher than the very best plate. If there are special requirements in the agreement, the same shall apply.

seventeen: The mounting hole in the positioning call must be a counterbore, and it is not allowed to become directly attached to the top surface area of the mold base.

18: When a custom cnc aluminum mold studying more than 8000KG is installed on the hypodermic injection molding equipment, the attach should be pressed by perforation, and the dish must not be pushed separately. Any time the equipment uses hydraulic locking molds, twist perforations must also be added to prevent the failure of the hydraulic mechanism.

19: The sprue bushing ball R is usually larger than the nozzle ball R with the injection molding machining.

20: The inlet diameter of the sprue bushing ought to be bigger than the diameter on the nozzle injection port.

11: The overall length and width of the conform must conform to the specified injection molding machine.

22: The surface of the mold starting will need to have pits, rust scratches, unnecessary jewelry, water, gas, oil loopholes, etc ., and other defects that affect the looks.

23: Each plate of the mold base must have a chamfer greater than 1 . 5mm.

24: The mold should be convenient to obtain hoisting and transportation, as well as the mold parts should not be disassembled during hoisting ( aside from the oils cylinder, which in turn needs to be offered for sale separately). The lifting wedding interferes with the faucet, oily fat cylinder, pre-reset rod, etc ., and the position of the training ring ditch could be adjusted.

25: Every mold part weighing a lot more than 10KG will need to have a suitable working out with eye pin. If not, corresponding measures must be taken to ensure that the component is easy to disassemble and install. The size of the ring and the positioning of this ring pit are designed according to the relevant organization standards.

19: If ejector mechanisms such as for example ejector rods and ejector blocks interfere with sliders, and so forth, there must be a forced pre-reset mechanism, and the very best platter has a reset travel button.

27: The cylinder core and disposition should be regulated by a travel around switch, plus the installation is definitely reliable.

28: The mildew oil separator ought to be fixed and reliable. The gas pipe linking the crucial separator and the oil cylinder should use a rubber tube, and the joint should make use of standard parts.

29: There must be trash nails on the thimble plate. The clamping equipment should be installed reliably, with positioning pins, symmetrical unit installation, no less than some (small molds can be 2).

30: If the injection molding machine adopts an extended nozzle, there must be enough space inside the placing ring to ensure that the complete nozzle with heating do-it-yourself of the standard injection molding machine can extend in.

31: Pretty much all inclined passes could be removed from a cup that flows through underneath plate as well as the thimble lower part plate and whose perspective is the same as the inclined best angle.

32: The bottom area of the screw mounting cup must be chiseled. Screws above M12 (including M12) should be (12. being unfaithful grade).
