Definitions
- the present invention generally relates to a tooling assembly for the ejection station of a blow-molding machine, and more particularly to a tooling assembly having quick change capabilities.
- Blow-molding machines typically include an ejection station where the finished product, such as a bottle, that is being manufactured on the blow-molding machine is ejected from the machine.
- the ejection station will include a plurality of ejector pins that raise and lower within the ejection station.
- the dial indexes a set of molded bottles to the ejection station
- the ejector pins engage the mouth opening of the bottles to hold the bottles centered when the molds open. This is necessary to keep the bottles from sticking to one of the mold halves, and remaining within the mold half after the molds have opened.
- the ejector pins retract and the bottles fall from the ejector pins down to a chute that carries the finished bottles out of the machine.
- the ejector pins are mounted on a plate that slide up and down within the ejection station as the dial indexed finished bottled to the ejection station.
- most blow-molding machines include a pair of slide rods onto which the plate with the ejection pins are mounted slides.
- it is necessary to completely disassemble the upper portion of the ejection station to allow the plate to be slide up and off the top of the slide rods. This process is very difficult and time consuming due to the complexities of the machine and the size and weight of the components involved. Therefore, there is a need in the industry for improved ejection station tooling which will allow the ejector pins to be removed and replaced more easily and quickly.
- an ejection station tooling assembly for a blow-molding machine includes an upper support and a lower spacer with a plurality of slide rods supported by and extending vertically between them.
- a tooling plate includes a top surface and a bottom surface and is mounted onto the slide rods for sliding movement between a retracted position, toward the upper support, and an engaged position, toward the lower spacer.
- An actuator is mounted onto the upper support and connected to the top surface of the tooling plate and is adapted to move the tooling plate between the retracted position and the engaged position.
- An adaptor plate is removably mounted to the bottom surface of the tooling plate and has a plurality of ejection pins mounted thereon. The adaptor plate is removable from the tooling plate to allow the ejection pins to be replaced.
- FIG. 1 is a perspective view of a tooling plate of the present invention
- FIG. 2 is a front view of the ejector station tooling of the present invention.
- FIG. 3 is a top view of the ejector station tooling of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
- the ejection station tooling assembly 10 includes an upper support 12 and a lower spacer 14 mounted thereon.
- a plurality of slide rods 16 are mounted between the upper support 12 and the lower spacer 14 and extend vertically therebetween.
- the slide rods 16 are made from a hard steel and include an polished smooth surface.
- a tooling plate 18 is mounted to the slide rods 16.
- the tooling plate 18 includes a top surface 20 and a bottom surface 22 and is mounted onto the slide rods 16 such that the tooling plate 18 can slide between a retracted position and an engaged position.
- the retracted position is where the tooling plate 18 is held up near the upper support 12, and the engaged position is where the tooling plate 18 is lowered down near the lower spacer 14.
- An actuator is mounted onto the upper support 12 to control the movement of the tooling plate 18.
- the actuator is a hydraulic cylinder 24 that includes a body 24a mounted to the upper support 12 and a shaft 24b that is bolted or otherwise connected to the top surface 20 of the tooling plate 18.
- the hydraulic cylinder 24 raises and lowers the tooling plate 18 between the retracted position and the engaged position. It is to be understood, that any other suitable device could be incorporated to control the movement of the tooling plate 18 including but not limited to a pneumatic cylinder, or an electric servo motor or other such device.
- An adaptor plate 26 is mounted to the bottom surface 22 of the tooling plate 18.
- the adaptor plate 26 includes a plurality of ejector pins (not shown) mounted thereon.
- the ejector pins are adapted to keep finished blow-molded parts centered as the molds retract. This is necessary to keep the finished parts from sticking to the neck mold halves as the neck mold halves open, thereby allowing the finished parts to drop down and out of the machine.
- the adaptor plate 26 includes a pair of knife guides 28 mounted to opposing ends of the adaptor plate 26.
- the knife guides 28 include wedges (not shown) that force the neck molds apart when the tooling plate 18 lowers to the engaged position.
- the tooling plate 18 includes a pair of alignment pins (not shown) extending down from the bottom surface 22 of the tooling plate 18 and the adaptor plate 26 includes a pair of corresponding apertures (not shown) adapted to receive the alignment pins to locate the adaptor plate 26 on the tooling plate 18.
- the alignment pins allow the adaptor plate 26 to be quickly mounted to the bottom surface 22 of the tooling plate 18 and insures that the adaptor plate 26 is positioned correctly on the tooling plate 18.
- the ejection station tooling assembly 10 includes a pair of front slide rods 16a and a pair of rear slide rods 16b.
- the front slide rods 16a are spaced from each other along a first center line 34 toward the front of the ejection station.
- the rear slide rods 16b are spaced from each other along a second center line 36 toward the rear of the ejection station.
- the first center line 34 and the second center line 36 are parallel to each other, such that the front pair and rear pair of slide rods 16a, 16b form a rectangular pattern when viewed from the top of the machine.
- the tooling plate 18 includes four apertures 38 extending therethrough to receive the slide rods 16.
- each of the apertures 38 includes a bushing (not shown) fitted to the diameter of the slide rods 16 to allow the tooling plate 18 to easily slide along the slide rods 16.
- the adaptor plate 26 has a width 40 that is less than the distance between the front slide rods 16a and the rear slide rods 16b. This is necessary to allow the adaptor plate 26 to fit between the front slide rods 16a and the rear slide rods 16b for removal and replacement.
- Traditional blow-molding machines include only a pair of slide rods wherein the. ejector pins are mounted to the a plate having a pair of apertures to receive the two slide rods. In these traditional machines, the upper tooling must be disassembled to allow the plate to be slid off the top of the slide rods so the tooling on the plate can be changed.
- the present invention also lends itself to retro-fitting of existing blow- molding machines, thereby making the changing of tooling in those machines more easily performed.
- the front slide rods 16a are spaced from each other the same distance as the pair of slide rods (now removed) originally in the traditionally constructed machine.
- the rear slide rods 16b are spaced apart that same distance. Accordingly, the length of the existing plate of that machine is longer than the distance between the slide rods of either the front or rear slide rod pairs 16a, 16b.
- the distance between the front and rear slide bars 16a, 16b is wide enough to accommodate the width of existing plates, thereby allowing the plates to be used as adaptor plates 26 and to be inserted and positioned between the front and rear slide rods 16a, 16b for installation and removal. This allows the ejector pins, which are mounted to the adaptor plate 26 to be removed from the machine without having to remove the upper tooling of the ejection station assembly 10.
