Description

Automatic locking mold structure for movable insert of shell mold

Technical Field

The utility model relates to an injection molding machine mould technical field especially relates to automatic mould structure that pins of movable mold insert of casing mould.

Background

The movable mold insert of the existing mold structure is not protected, the movable mold insert is not placed in place to cause the mold to be crushed, the movable mold insert cannot be produced, the movable mold insert is placed into the mold by a mechanical arm, but sometimes the movable mold insert is not placed in place, slight movable mold insert is not placed in place to cause the product to be bad, serious movable mold insert is not placed in place to cause the mold to be crushed, the movable mold insert cannot be produced, the mold repairing period is long, the cost is high, the product delivery period is influenced, the technical problem is solved, the movable mold insert of the mold structure is required to be involved to meet the confirmation that the movable mold insert is placed in place, the mold cannot be crushed, the production cannot be carried.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, increase automatic pinning mechanism in the mould structure, guarantee that movable mold insert puts the affirmation of position.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the automatic locking die structure for the movable insert of the shell die comprises an A plate, a sliding block, an induction switch, a B plate, an ejector pin, a die core, an oil cylinder, a locking block and the movable insert, wherein the induction block is fixed on the sliding block through screws, the induction switch is arranged below the induction block and fixed on the B plate, the oil cylinder is arranged on the B plate, the ejector pin is fixed on the ejector plate, and a nut is screwed on the movable insert.

In a further technical scheme, the mold core is provided with a thimble groove which plays a role of guiding a thimble.

Further technical scheme, the locking piece passes through the screw fixation on the sliding block.

According to the further technical scheme, the inductive switch is connected with a PLC (programmable logic controller) of the injection molding machine.

Compared with the prior art, the beneficial effects of the utility model are that:

when the mold is opened, the plate A and the plate B are separated, the oil cylinder moves to push the sliding block, and the locking block is fixed on the sliding block, so that the locking block is separated from the movable insert. At this time, the ejector plate moves under the action of the ejector force of the injection molding machine, and the ejector pins eject the movable insert and the product together. Taking out the product and the movable insert by the manipulator;

when the mold is closed, the ejector pin returns, the movable insert with the nut screwed on is placed into the mold through the mechanical handle, in order to confirm that the movable insert is placed in place, the oil cylinder pushes the sliding block, and the locking block on the sliding block locks the movable insert. The induction block touches the induction switch, and after an induction signal is input to the PLC controller of the injection molding machine, the mold is controlled to be closed; the induction block and the induction switch of the design are matched with each other, so that the movable insert on the mold is placed in position for confirmation, the mold is not damaged by pressure, the production stability is improved, and the mold repairing cost is reduced.

Drawings

Fig. 1 is a structure of the shell mold with a movable insert for automatically locking the mold;

fig. 2 is the utility model provides an automatic A portion enlarger that pins mould structure of casing mould movable mold insert.

In the figure: 1-A plate; 2-a sliding block; 3-an induction block; 4-an inductive switch; 5-B plate; 6-ejector pin plate; 7-a thimble; 8-mold core; 9-oil cylinder; 10-locking block; 11-a removable insert; 12-nut.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1;

referring to fig. 1-2, the structure for automatically locking the movable insert of the shell mold comprises an a plate 1, a sliding block 2, an induction block 3, an induction switch 4, a B plate 5, an ejector plate 6, an ejector pin 7, a mold core 8, an oil cylinder 9, a locking block 10, a movable insert 11, wherein the induction block 3 is fixed on the sliding block 2 through screws, the induction switch 4 is arranged below the induction block 3 and fixed on the B plate 5, the oil cylinder 9 is arranged on the B plate 5, the ejector pin 7 is fixed on the ejector plate 6, and a nut is screwed on the movable insert 11.

In the utility model, the mold insert 8 is provided with a thimble groove, which plays a role of guiding the thimble 7.

The utility model discloses in, locking piece 10 passes through the screw fixation on sliding block 2.

The utility model discloses in, inductive switch 4 is connected with injection molding machine PLC controller electricity, and the control mold closing action.

When the injection molding machine is used specifically, when the mold is opened, the plate A and the plate B are separated, the oil cylinder moves to push the sliding block, the locking block is separated from the movable insert because the locking block is fixed on the sliding block, the ejector plate moves under the action of the ejector rod force of the injection molding machine at the moment, the ejector pin ejects the movable insert and a product together, and the product and the movable insert are taken out by the manipulator;

when the mold is closed, after the thimble returns, the movable insert of the nut 12 is screwed on by the mechanical handle and is placed into the mold, in order to confirm that the movable insert is placed in place, the oil cylinder pushes the sliding block, the locking block on the sliding block locks the movable insert, the induction block touches the induction switch, and the induction signal is input to the injection molding machine and then the mold is closed; the induction block and the induction switch of the design are matched with each other, so that the movable insert on the mold is placed in position for confirmation, the mold is not damaged by pressure, the production stability is improved, and the mold repairing cost is reduced.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
