Description

A kind of new HALF blocks mold-opening structure

Technical field

The present invention relates to a kind of new HALF blocks mold-opening structure applied to mould die sinking field.

Background technology

HALF blocks (one of them of two half blocks to form a whole) structure is the common structure in mould applications, is led to The die sinking of normal HALF blocks realized by oblique cutting in moving up and down for two HALF inclined guide pillars in the block, this inclined guide pillar die sinking Structure has a defect that：Due to that must have the pilot hole for coordinating inclined guide pillar installation on HALF, HALF blocks will be made quite big, Material cost is high；Inclined guide pillar is adapted to mold within 30 degree of angles, is not suitable for more than 30 degree of angles molding, whole HALF blocks mold-opening structure body Product is big, can occupy larger die space；The chamber number of mould is done not high in same specification injection molding machine, and production efficiency is low；Inclined guide pillar The inclined hole of installation and the size of hanging platform are difficult to control, and are unfavorable for processing, and size is difficult to ensure unification；Inclined guide pillar discontinuity is easily damaged Bad, maintenance cost is high, once damage cost allowance will be up at least hundreds of thousands, and inclined guide pillar dismounting is inconvenient, mould during dismounting The necessary complete machine of tool, which is left office, to be replaced, and maintenance time length, downtime length, influence manufacturing schedule and efficiency.

The content of the invention

For solve above-mentioned technology there are the defects of, the present invention is intended to provide a kind of new HALF blocks mold-opening structure, it is at least With it is compact-sized it is small, be hardly damaged, greatly reduce equipment processing and maintenance cost, it is easy to process and control, mould The advantages that increase of chamber number, production efficiency greatly improve, are easy to loading and unloading.

The specific content of the invention is as follows：

A kind of new HALF blocks mold-opening structure, including the HALF blocks of two mutual cooperations, ejector sleeve, the spiral shell being located inside ejector sleeve Line core and interior core, described two HALF blocks mosaics are equipped with sealing hole, and the lower face of each HALF blocks is equipped with to sealing The inner wall in hole tilts and extends to the die sinking inclined-plane of sealing hole inner wall, the die sinking inclined-plane edge die sinking direction on the inner wall of each sealing hole Mutually contradictory setting, the ejector sleeve both sides are equipped with and two die sinking matched die sinking slopes in inclined-plane.

One of preferably, described two HALF blocks are respectively equipped with fixed parallel to the both sides in die sinking direction Slider guide, the side of described two HALF blocks are contacted with the slider guide, and are limited by slider guide along slider guide length direction Slide, the slider guide also limits the upward displacement of the HALF blocks.

Further, the HALF blocks are in the both sides contacted with the slider guide, be respectively equipped with it is outwardly slide side, The slider guide is sliding matched slideway with described slide when contact position is equipped with sliding.

One of preferably, ejector sleeve top both sides are equipped with die sinking reinforcing rib, and the die sinking slope is located at The top of the die sinking reinforcing rib.

One of preferably, described two HALF blocks are equipped with oblique tight block perpendicular to the both sides in die sinking direction.

One of preferably, the angle of inclination on the die sinking slope on the ejector sleeve is 0-45 degree, described each The angle of inclination on the die sinking inclined-plane on HALF blocks is engaged with molding the angle of inclination on slope.

Further, the tiltedly tight block and HALF blocks contact position are equipped with inclined inclined-plane laterally, the HALF blocks with tiltedly Tight block contact position be equipped with the matched slope in the inclined-plane, make tiltedly tight block to HALF blocks move when, two HALF blocks are close to each other Moved down while split.

Beneficial effect：

Sealing hole inner wall two of the invention by being formed under the die sinking slope at the top of ejector sleeve and two HALF block split states The die sinking inclined-plane of side is to cooperation, and when the ejector sleeve is above pushed away, two HALF blocks separate to both sides and realize and mold respectively, simple in structure, The mold-opening structure of inclined guide pillar formula is eliminated, the volume for reducing HALF blocks and the manufacture for reducing die apparatus and processing cost, Mold cavity number can do height, improve production efficiency, while the installation inclined hole for also solving inclined guide pillar control bad with hanging platform size, The problem of not easy to be processed, reduce the maintenance cost of mould, adds the service life of mould, reduces maintenance frequency, 45 degree It can be applied well below angle, mold function is greatly enhanced.
