Definitions

  • This invention relates to a mould sorting table, and one object is to provide a table which can be used in conjunction with a standard injection moulding machine to enable a mould to be loaded with an insert for insert moulding,while a moulding operation is being performed with another mould, while yet the operator can be in a central position.
  • a mould sorting table for operation with an injection moulding machine defines a transfer position for a mould half and left and right loading positions, together with means for moving a mould half to and from the transfer position from, or to, any of a moulding position on the machine, and the two loading positions.
  • a mould from the machine can be moved to the transfer position, and then that mould can be moved to one leading position while a mould in the other loading position can be moved to the transfer position ready for being moved to the moulding position.
  • the arrangement is most convenient if the transfer position and the left and right loading positions are in a straight line, constituting the top of a 'T' while the- moulding position or the machine is in the position of the leg of the 'T' .
  • a mould half can be simply slid from the transfer position to any one of the other three positions. Also as a. mould half is moved between the transfer position and the right leading between the other moulding position and the transfer position.
  • the moving means can be constituted by one or more hydraulic or other actuators operation of which is initiated by limit switches responsive to arrival of a mould half in one of the positions.
  • the invention includes a method of moulding using an injection moulding machine and a mould sorting table as defined above, in which method one mould is being loaded with an insert in one of the loading positions, while moulding is being performed en another mould in the moulding position.
  • FIGURE 1 is a perspective view of a vertical moulding machine fitted with a shuffle table
  • FIGURE 2 is a plan view of the mould base and the shuffle table.
  • FIGURE 3 is a detail taken in the direction of the arrow III in FIGURE 1.
  • the moulding machine comprises a moulding table
  • a shuffle table 16 is fitted to the front of the moulding table 11.
  • the shuffle table defines four mould half positions as shown in FIGURE 2.
  • the mould table 11 defines position number 1 which is the position for a mould half during moulding; then position 2 and position 4 are left-hand and right-hand loading and ejection positions on either side of position 3 which constitutes a transfer station, and is in front of position 1.
  • a mould half 12 loaded with its insert is ready for closing with the mould half 14 and injection moulding, and a second mould half 17 is in the left-hand unloading station shown as position 2 in FIGURE 2.
  • the mould half can be unloaded and have fresh inserts fitted for a next moulding by an operator positioned in front of the shuffle table at 18, and that unloading and reloading can take place while injection is being performed at position 1.
  • the mould head 13 rises and then a hydraulic actuator 19 is operated to push the mould half 12 into the transfer station-position 3 - and when it is properly located a signal is given by a limit switch (net shown).
  • An actuator 21 then pushes the mould halves 17 and 12 from positions 2 and 3 to positions 3 and 4 respectively .
  • the actuator 19 draws the mould half 17 onto the mould base position 1, and when it is fully home, another limit switch gives a signal for mould closing and injection moulding to commence.
  • There is a 'T' slot in the back face of each of the mould halves for automatically engaging with a corresponding "T" on the head of the actuator 19 enabling the actuator to both pull and push the mould halves between positions 1 and 3.
  • a key 26 in a keyway in the bottom face of the cross-head can slide to and fro along a slot 27 in the centre of the table 16, so that when the actuator 19 operates, the cross-hand is guided laterally.
  • the T head slides from the s lot 24 in one plate to the slot 24 in the other .
  • the shuffle table 16 with its actuators 21 and 22 is simple and inexpensive, and can be fitted to a standard vertical injection moulding machine and readily removed when normal injection moulding is to be done. When in use the shuffle table allows full use of the mould clamping area and doubles the production capacity of the machine when doing insert moulding work because one mould half can be loaded with its inserts while the other mould half is being used in a moulding operation.
  • the positioning of the able as shown enables an operator at 18 to be comfortably seated centrally in a position where he can easily remove mouldings and reload inserts, while yet he has an unobstructed view of the mould base after each moulding operation. It will be clear that the shuffle table can be fitted to various kinds of moulding machines including machines with two

Abstract

Table de triage de moules (16) destinee a etre utilisee avec une machine (13) de moulage par injection conventionnelle pour effectuer un moulage par insertion. Pendant qu'un moulage est en train d'etre execute sur un moule (12, 14) dans une position de moulage (1) une autre moitie de moule (17) est dechargee du moulage pour etre chargee avec une nouvelle injection. La moitie de moule (12) est ensuite avancee dans la position (3) par un dispositif d'actionnement (19) et les moities de moule (17) et (12) sont deplacees dans les positions (3) et (4) et ensuite la moitie de moule (17) est retiree par le dispositif d'actionnement (19) dans la position (1) pour l'operation de moulage suivante tandis que le moulage precedent est extrait de la moitie de moule dans la position (4).
