Abstract

The utility model provides a demoulding mechanism of a soft rubber injection mould with an inner-shrinkage slide block structure, which comprises a mould core and four inner-shrinkage slide blocks arranged on the outer side of the mould core, wherein the four inner-shrinkage slide blocks are respectively clamped with the mould core, a conical push block is also arranged between two adjacent inner-shrinkage slide blocks, and the push block is in sliding connection with the mould core. The demoulding device is simple in structure and high in practicability, and due to the action of the pushing block and the fact that the pushing block is of a conical structure, the conical pushing block extrudes the inwards-retracted sliding block outwards, so that demoulding is achieved; the utility model is suitable for the soft rubber injection mold, and can realize the demolding of the product without designing a corresponding ejection mechanism.

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production.

The conventional plastic product completes the forming or ejection and demolding actions, which are usually realized by a common ejection system, so that if the plastic product is a special soft rubber material, for example, the product is a TPU (thermoplastic polyurethane) soft rubber type material, the ejection system cannot be designed on a mold, and the existing mold ejection system cannot realize the forming and demolding actions of the corresponding plastic product.

The patent CN107791469A discloses a soft rubber pneumatic blow-out demoulding mechanism injection mould, which comprises a ventilating push tube, an ejection core pin, a push tube snap ring, a snap ring cover plate, a snap ring upper seal ring, a vent plate, an air nozzle, a core pin lower seal ring, a core pin lock head screw, a vent plate guide post, an upper mould base plate, a stripper plate, a guide post, a cavity fixing plate, a core fixing plate, a movable mould base plate, an ejection connecting rod, a mould foot cushion block, a thimble cover plate, a thimble push plate, a lower mould base plate, a reset spring, a reset rod, a cavity pull rod, a stripper plate pull rod, a resin shutter, a cavity insert and a core insert, wherein the pneumatic blow-out demoulding mechanism is utilized to realize demoulding, the defect that the conventional ejection modes such as push plate ejection and thimble ejection cannot be adopted when a small-size product is small and the shape of a parting surface is irregular in a moulding injection moulding process is overcome, and the ejection function of the product is realized by using a simple pneumatic ejection mechanism, the automatic molding production of the mold is realized.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the demoulding mechanism of the soft rubber injection mould with the inward-shrinkage sliding block structure, which realizes demoulding action by utilizing the action in the mould opening process.

The technical scheme of the utility model is as follows: the utility model provides a flexible glue injection mold's that contracts slider structure demoulding mechanism, includes the mold core to and set up four in the mold core outside the slider that contracts, four the slider that contracts in respectively with the mold core joint, and in the double-phase adjacent still be provided with conical ejector pad between the slider that contracts, ejector pad and mold core sliding connection.

Preferably, a T-shaped fixture block is arranged on the outer side wall of the mold core, and a clamping groove used for being matched with the T-shaped fixture block is formed in the inward-retracting sliding block.

Preferably, the outer side wall of the mold core is further provided with a slide rail, and the push block is provided with a slide groove matched with the slide rail along the length direction.

Preferably, a slot is arranged between the two adjacent inward-retracting sliding blocks, the slot is of a conical structure, and the sliding rail is arranged in the conical slot.

Preferably, the retracted slide block is of a T-shaped structure.

Preferably, the upper end of the inward-shrinkage sliding block is further provided with a stop block, and the stop blocks are fixed on two side walls of the inward-shrinkage sliding block through bolts so as to block the push block.

The utility model has the beneficial effects that:

1. the demoulding mechanism is simple in structure and strong in practicability, and through the action of the push block, the push block is in a conical structure, so that 4 sliding blocks contract inwards in the process that the conical push block moves towards the backward mould direction, and demoulding is realized;

2. the utility model is suitable for the soft rubber injection mold, and can realize the demolding of the product without designing a corresponding ejection mechanism.
