Abstract

The utility model discloses an insert forming die, which is used for forming plastic products with inserts. An insert is provided with an inserting portion and an extending portion, the die comprises an upper die, a lower die and a clamping mechanism, the upper die is provided with a cavity, the inserting portion extends into the cavity, the extending portion is inserted in the lower die, and the clamping mechanism is assembled on the lower die and used for clamping the extending portion of the insert. When the insert forming die is opened, as the clamping mechanism can clamp the extending portion of the insert, a plastic product can not be adhered onto the upper die, and further the plastic product can not be crushed by the insert forming die when the insert forming die is closed again.

Description

The inserts mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of product that can prevent and binds the inserts mould of mould.

Background technology

See also Fig. 1, it has disclosed a kind of inserts mould 100 ', it is used for the plastic products that moulding has inserts 30 ', inserts 30 ' has Embedded Division 31 ' and extension 32 ', this inserts mould 100 ' comprises a patrix 10 ' and a counterdie 20 ', patrix 10 ' is provided with a die cavity 11 ', and Embedded Division 31 ' stretches in the die cavity 11 ', and extension 32 ' stretches in the counterdie 20 '.

But above-mentioned inserts mould 100 ' is when die sinking, and plastic products bind on patrix 10 ' easily, thereby plastic products is damaged by pressure when causing last matched moulds easily.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of product that prevents to be bonding on the inserts mould of patrix.

For achieving the above object, the utility model provides a kind of inserts mould, is used for the plastic products that moulding has inserts, and inserts has Embedded Division and extension, and this mould comprises a patrix, a counterdie and a clamping device.Patrix is provided with a die cavity, and described Embedded Division stretches in this die cavity, and extension inserts in the counterdie; Clamping device is installed on the counterdie, but the extension of clamping inserts.

As mentioned above, the utility model inserts mould when die sinking, but because the extension of clamping device clamping inserts, thereby can prevent that plastic products from binding on patrix, and then can prevent to damage plastic products once more during matched moulds by pressure when the inserts mould.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 2 and Fig. 3, the utility model inserts mould 100 is used for the plastic products that moulding has inserts 40, and inserts 40 has Embedded Division 41 and extension 42, and this inserts mould 100 comprises a patrix 10, a counterdie 20 and a clamping device 30.

Offer a die cavity 11 on the described patrix 10, offer a fluting 21 on the described counterdie 20, counterdie 20 tops offer the holding tank 22 that runs through counterdie in fluting 21 both sides, are plugged with several modules 23 in the fluting 21, and module 23 tops offer a storage tank 24 downwards.

Described clamping device 30 is installed on the counterdie 20, and it comprises two grip blocks 31.

When carrying out injection mo(u)lding, earlier the extension 42 with inserts 40 inserts in the storage tank 24 of counterdie 20, and two grip blocks 31 are fixed in that clamping extension 42 is with fixing with inserts 40 in the holding tank 22, and the Embedded Division 41 of inserts 40 is exposed to counterdie 20 upper surfaces.During die sinking, two grip blocks, 31 clamping inserts, the 40 motionless plastic products that make can break away from patrix 10 fully.Extension 42 can be deviate between grip block 31 by strain takes place when taking out plastic products.

In sum, but the utility model inserts mould 100 because the extension 42 of clamping device 30 clamping inserts 40, thereby can prevent that plastic products from binding on patrix 10, and then can prevent to damage plastic products once more during matched moulds by pressure when inserts mould 100.

The utility model inserts mould 100 is not limited to the above-mentioned specific embodiment, as: clamping device can be, comprise be installed in the grip block on the counterdie slidably and be installed in counterdie and grip block between spring, spring is resisted against on the grip block.
