Description
Technical Field
The utility model relates to an injection molding device especially relates to a work piece mould nut positioning mechanism moulds plastics.
Background
At present, when a plurality of injection molding workpieces are molded, nuts need to be embedded on the workpieces, in the prior art, the nuts are generally arranged in a mold cavity of a mold injection molding machine by using a conventional embedding needle, the nuts lack positioning performance, so that plastic is injected into the mold cavity, the nuts are easy to rotate and shift, after the injection molding workpieces are molded, the positions of the nuts are easy to have the conditions of rubber coating, glue overflow and the like, according to the current data statistics, the reject ratio caused by the rubber coating and the glue overflow accounts for about 30%, so that the injection molding production process of the plastic parts is not only time-consuming and labor-consuming, the raw material loss is large, but also the product quality is unstable, and the production requirements cannot be met.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in, to prior art's not enough, provide one kind and can play the positioning action to the nut, can avoid the nut to take place to rotate when the injecting glue, and then improve the product yield, save the injection molding work piece intramode nut positioning mechanism of cost.
In order to solve the technical problem, the utility model adopts the following technical scheme.
The utility model provides a work piece mould nut positioning mechanism moulds plastics, its is including mould slider and slider mold insert, the one end of slider mold insert is equipped with the nut and inlays the needle, be formed with the locating piece on the mould slider, just the nut inlays the needle and stretches out to the locating piece direction, the nut inlays the last cover of needle and is equipped with the nut, the terminal surface of nut support tightly in the locating piece, borrow by the nut inlay the needle with the cooperation of locating piece will the nut is positioned in the die cavity.
Preferably, two positioning blocks are formed on the die sliding block, the two positioning blocks are arranged side by side, and the end face of the nut abuts against the two positioning blocks.
Preferably, a gap is formed between the two positioning blocks.
Preferably, the end of the nut insert pin is inserted between the two positioning blocks.
The utility model discloses an among the work piece mould of moulding plastics mould nut positioning mechanism set up the locating piece that is used for the butt nut on the mould slider, before moulding plastics, locate nut cover earlier on the nut inlays the needle, treat mould slider motion targets in place the back, the terminal surface of nut support tightly in the locating piece, through the nut inlay the needle with the cooperation of locating piece will the nut is located the die cavity, when injecting the plastic in the die cavity, because of the nut rigidity can be avoided the nut receives the injecting glue influence and takes place to rotate, shift, has improved the product yield of the work piece of moulding plastics from this greatly, can avoid the material extravagant simultaneously, helps saving manufacturing cost.

Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings and examples.
The utility model discloses a nut positioning mechanism in injection molding workpiece mould combines fig. 1 to 4 shown, it is including mould slider 1 and slider mold insert 2, the one end of slider mold insert 2 is equipped with the nut and inlays needle 3, be formed with locating piece 4 on the mould slider 1, just the nut inlays needle 3 to the 4 directions of locating piece stretch out, the nut inlays 3 shanks the cover of needle and is equipped with nut 5, the terminal surface of nut 5 support tightly in locating piece 4, borrow by the nut inlay needle 3 with the cooperation of locating piece 4 will nut 5 is located the mould intracavity.
In the mechanism, the positioning block 4 used for abutting against the nut 5 is arranged on the die sliding block 1, the nut 5 is firstly sleeved on the nut insert pin 3 before injection molding, after the die sliding block 1 moves in place, the end face of the nut 5 abuts against the positioning block 4, the nut insert pin 3 is matched with the positioning block 4, the nut 5 is positioned in a die cavity, when plastic is injected into the die cavity, the nut 5 is fixed in position, so that the nut 5 is prevented from rotating and shifting due to the influence of glue injection, the product yield of the injection molding workpiece 100 is greatly improved, meanwhile, material waste can be avoided, and the production cost is saved.
As a preferable mode, two positioning blocks 4 are formed on the die slide 1, the two positioning blocks 4 are arranged side by side, and the end surface of the nut 5 abuts against the two positioning blocks 4. The two positioning blocks 4 can be more tightly abutted and matched with the nut 5.
Further, a gap is formed between the two positioning blocks 4.
In this embodiment, referring to fig. 4, the end of the nut insert pin 3 is inserted between two positioning blocks 4. The above structure enables the nut insert pin 3 and the positioning block 4 to be more reliably engaged, and the nut 5 is stably fixed between the nut insert pin 3 and the positioning block 4.
The utility model discloses an among the work piece mould internal nut positioning mechanism moulds plastics, the nut is fixed in the mould intracavity by the locating piece, and when the injecting glue, the nut can't rotate, and then avoids the conditions such as rubber coating, excessive glue to appear, has improved the qualification rate of work piece greatly, through data statistics, based on the utility model discloses an injection moulding production defective rate can be reduced to 3% by 30%, and raw and other materials loss is reduced to 3% by previous 10%, and the human cost reduces to 1 people by previous 2 individuals and can accomplish, and manufacturing cost reduces by a wide margin.
The above is only the embodiment of the present invention, and is not intended to limit the present invention, and all modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included within the protection scope of the present invention.
