5.What is the Collapsible core characteristic?

The Collapsible core characteristic is as below.
1)Ingenious structure to move and de-mold in limited space.
2)High precision and consistency of parts.
3)Cold processing technology for high hardness materials.
4) Safe and reliable multi-cavity injection mold mechanical structure, so that the mold size is smaller.

6. What is the consist of Collapsible Core?

The Collapsible Core is a three-unit assembly designed for simplicity of installation, reliability in operation, and long life. The three units are a Collapsible Core, a center pin, and a positive collapse sleeve.
1)The center core
2) 6 external segments
3) Movable rings
4)2 half rings
5)The cooling bore
6)A sealing groove for the O ring
7)a locking pin

7.What is the Center Pin use for in the consist of Collapsible Core?

Center Pin serves to expand the segments of the Collapsible Core to their molding position and holds them at this diameter.

8.What is the Desired Sequence of Operation of Collapsible Core for Automatic Mold Operation?

The molding sequence can easily be followed by starting with the opening of the press:
The press opens and the mold parts at the main parting line. When sufficient mold open is achieved, the ejector plate assembly is moved forward by mechanical or hydraulic knockouts of
the press. The ejector plate assembly with the collapsing core is moving forward the necessary stroke required to move the core off of the center pin and collapse the core (this is the first stage of ejection).

If the segments of the core fail to collapse for any reason during this stage, the positive collapse sleeve will come into play and ensure the start of the collapse. In addition, the stripper plate and ejector plate assembly move together because of the return pins located directly under the stripper plate. This simultaneous movement continues until the ejector plate assembly is full forward. At this point, a limit switch is actuated. This, in turn, actuates the cylinders to take over and to continue to move the stripper plate with the stripper insert, moving the part
away from the collapsed core (second stage).

9.What stage is used to determine if a part can be molded on the Collapsible Core?

1)Undercut
2)Loss of Collapse
3)Shrinkage
4)Clearance

10.What is the Mold Design Check List of Collapsible Core?

1)Use guided ejector plates and a support ring around the center pin. Ejector plate, support rings, and rest buttons must be ground to 1.187 .001.
2)Use springs to assure the first break at the main parting line.
3)Return pins to end under stripper plate.
4)Ejector plate travel to specifications. Stamp dimension on edge of the plate.
5)Secondary stripper plate actuation to begin only after full ejector plate travel. The stripper plate must return fully before the ejector plate begins to return (see Sequence Description).
6)Good venting is essential, preferable to the outside of mold.
7)Clearance between core shut-off O.D. and stripper insert I.D. to be .0010/.0015 total. Measure core when installed in the mold. No tapered shut-off permitted. Avoid excessive shut-off length; .150/.250 is adequate.
8)Mounted core to be free to turn when in ejector plate assembly.
9)Center pin to be concentric with stripper bushing. Verify protrusion of pin through core and radius on tip of the pin.
10)Positive collapse sleeve to travel freely through plates. Apply grease where indicated. Check for free movement when mold is at operating temperature.
11)When the face of Collapsible Core segments shut-off against the cavity (some parts with through holes), all cores must be ground to the same O.A.L. Normal tolerance of .003 is inadequate. Refer to Core Grinding Instructions. Clearance between the end of the core face and cavity to be .0005 to .00.
12)Do not pre-load the core. Whenever the above condition exists, an early ejector plate return system must be used, or the cores will be destroyed. NOTE: This applies only when the core seals off against the cavity. When the pin is seating against the cavity exercise care to avoid excessive pre-load of the pin. A .000 to .0015 interference is adequate.
13)Break all sharp corners.
14.)The stripper shut-off diameter must be of the same diameter or preferably a larger diameter than any other diameter on the core.

 

11 What types of Collapsible Core?

The types of Collapsible Core are as below:
1)Dovetail Collapsible Core
Positive, mechanically actuated collapsible cores that eliminate complex gear and rack approaches, resulting in a simpler mold and a faster cycle time.

2)RT Collapsible Core
Parts with internal protrusions, dimples, interrupted threads, and cutouts can now be economically produced on a high or low volume basis.

3)Expandable Cavities
Developed to mold parts with external details such as threads, ribs, grooves, barbs, and dimples, without the need for conventional side action components.

15.What is the feature of the collapsible core?

The feature of the collapsible core are as below:
The design of each collapsible core is customized so that the core can be manufactured in accordance with the customer´s specifications. This will make it possible to produce a wide variety of contours with diameters ranging from 8mm to 240mm and a contour length of up to 130mm. The overall length of the collapsible cores will be determined individually.

16.Why collapsible core is so important to cut down the cost?

The collapsible core is the ideal solution for removing injection molded parts with undercuts
or claws or threaded parts in a cost-effective way from the mold.12% of the undercuts can be removed without any problems – in special cases even 17%.

17.Why Choose Collapsible Core?

1)The Zydron Core Zydron Core is created using the latest wire technologies.
2)This process allows our part to hold tighter tolerances giving you a longer life with fewer production slowdowns.
3)Straight Pin allows more contact surface between the center pin and the collapsible core improving thermal transfer thus decreasing cycle time and lowering production costs.
4)Our Flush Style Core product has a pin that does not need to protrude past the sleeves.
This allows for the product design to be maintained and not altered. This in effect reduces the volume of plastic being molded per part by having a thin top surface of the part lowering material cost.

18.What is the feature of the collapsible core mold?

Effortless demolding/ejection of parts with undercuts, protrusions, or cut-outs ansible Core Injection Molds

19.What is needed to check the finish on Collapsible cores?

Surface finish and polish
Undercuts and back-hooks in direction of collapse due to improper grinding
Compliance with proper design procedures.

20.What is the Collapsible core characteristic?

(1) Ingenious structure to move and de-mold in limited space.
(2) High precision and consistency of parts.
(3) Cold processing technology for high hardness materials.
(4) Safe and reliable multi-cavity injection mold mechanical structure, so that the mold size is smaller.
