Mould Design The Material
Jul 31, 2017

The use of rules: fixed parts, positioning pieces, Mould Design between the sliding parts, the choice of material and hardness, according to the ease of processing to be appropriate deployment. Objects and objects between the sliding with the need to use different materials or the same material, Mould Design with different hardness to use. In order to make the loss tolerance emphasis on a single object, the sliding material between the material and hardness can not be the same.

Action principle: A beam block down, dovetail groove or T-slot drive BSLIDE to shrink to achieve the purpose of stripping

Note: Dove tail is the top of the finished product, Mould Design the dovetail groove not through the finished product, because through the mold will cause difficulties; and poor mold will make the plastic into the sliding surface caused by mold damage. SLIDE after mold opening

Stripping distance on both sides add up to less than D. The strength of size C should be sufficient

Action principle: When the PL surface is open, Mould Design the use of SPRING through COREPIN push DISCINSERT, along the center of DISINSERT rotation, to achieve the purpose of release.

Note: COREPIN and DISCINSERT with the A gap should not be too large, Mould Design to avoid DISCINSERT rotation angle> 45 degrees, resulting in mold die when the broken DISC INSERT mechanism This mechanism is only applicable to the small distance of the hook; Mold angle, should pay attention to whether enough

When PL1 open mode when the A beam block down, highlight the space, Mould Design male and female template (PL2) and then open, the use of oblique tip (PIN), the SLIDE dial to the inside, to release the purpose.

Note: shrink SLIDE trip to be limited, to avoid hit the finished product. Mould Design Such a design, the general SLIDE will be more fragile, need to do spare.

When the distance at the D is greater than the allowable travel distance at E,Mould Design it is not possible to use "B" and "C" SLIDE with sufficient travel space to do the internal action. The SLIDE drive mode can be made with the tip (right) or stop (left). Use the oblique way, the required space (travel) larger; Mould Design use the block way, the required space (travel) smaller. Mould Design The design of the oblique tip can handle larger tripping strokes, but the space needs to be larger; the dovetail groove is designed for short stroke and the space required is also small.

Action principle: When the PL surface is open, the use of inclined to drive SLIDE to achieve the purpose of release.

Note: SLIDE range if the RIB or BOSS need to try to (or next) plus the top of the tip to avoid finished sticky male mold in the SLIDE range of the top of the tip is not easy to arrange "A" need to meet in order to prevent positioning uncertain.

Action principle: there are internal sliders, Mould Design do not use the dovetail groove structure, and use two BLOCK to form a chute, as shown. Mould Design If the dowel trough is to be used as the structure requires, Mould Design the spring should be added to the outside of the inner slide.

Action principle: When the mold is ejected, the two-stage ejector mechanism first separates the male mold plate 7 from the bearing plate 9, and the male mold plate 7 drives the inner slide block 1 to move upward, Mould Design and at this time, The block will follow the two oblique guide groove up to the right movement, Mould Design so as to complete the finished product hook action. If the spring 3 is not applied, the inner slide 1 is bitten due to friction with the block 5 for a long time.

After the spring 3 is added, Mould Design since the slider 1 is in contact with the block 5 during each movement, the contact area is large and it is not easy to bite.

Features: in the inner slide to increase the side of a spring will make the inner slider more smooth operation, and the inner slide is not easy to bite.
