Abstract

The utility model relates to a filter net plastic injection mould, comprising an upper mould which is a moving mould and lower moulds which are fixed moulds. The upper mould comprises a moving mould fixing plate, a sprue plate and a moving mould plate; the upper mould is also internally provided with an inclined guide pole whose outward has a slipper block which leans on the inclined guide pole; the lower mould has two and each lower mould comprises a fixed mould fixing plate and a fixed mould plate; the fixed mould plate is fixed on the fixed mould fixing plate and immovably connects a pulling block which pulls the slipper block; the lower mould is also internally provided with a mould core which is connected with the handspike of an oil cylinder; the sprue plate, the moving mould plate and the fixed mould are linked by a guide pole; the moving mould plate and the fixed mould plate circle to form a mould cavity which has hot runners to connect with; the lower mould plate is internally provided with a top plate which is provided with a top pole and the top pole extends into the mould cavity. The utility model designs the slipper block on the upper mould and makes the lower mould just have a mould core, guaranteeing the simple structure and contributing to the putting and fixing of the net; the utility model adopts one upper mould and two lower moulds to overcome the weak point of long period.

Description

A kind of filter webs injection mold

(1) technical field

The utility model relates to a kind of filter webs injection mold.

(2) background technology

The filter webs injection mold belongs to injection moulding bag net class mould, and fixing, the injection mo(u)lding sealing of screen pack on the injection mold core has suitable difficulty, and existing filter webs injection mold does not address this problem as yet well, and the production cycle of product is longer relatively.

(3) summary of the invention

In order to overcome the above-mentioned deficiency of existing filter webs injection mold, the utility model provides a kind of reduces injection mo(u)lding sealing difficulty, effectively shorten the filter webs injection mold of life cycle of the product.

The technical scheme in the invention for solving the technical problem is: a kind of filter webs injection mold, comprise upper die and lower die, described patrix is a dynamic model, described counterdie is a cover half, described patrix comprises dynamic mould fixing plate, draws flitch and moving platen, and described moving platen and described dynamic mould fixing plate are fixed; Also be provided with Angle Pin in the described patrix, there is slide block in the outside of Angle Pin, and described slide block leans on mutually with described Angle Pin; Described counterdie has two, each counterdie comprises cover half fixed head and solid plate, and described solid plate is fixed on the described cover half fixed head, and described solid plate is also affixed with the pulling block that is used to spur described slide block, also have core in the counterdie, described core is connected with the push rod of an oil cylinder; Described flitch, moving platen and the solid plate of drawing worn even by guide pillar, and an end of described guide pillar is a free end, and the other end is fixed on the described dynamic mould fixing plate; Described moving platen and described solid plate surround die cavity, and described die cavity has hot flow path to be communicated with it, in the described die cavity top board are arranged, and described top board also is provided with push rod, and described push rod stretches in the described die cavity.

Further, also be equipped with the spacing blind rivet between described moving platen and the described solid plate.

In the die sinking process, at first by loose core of oil cylinder, then moving platen separates with drawing flitch, to guarantee that stub bar can take out from sprue, moving platen slowly separates with solid plate then, in this process, slide block leads under the pulling of pulling block and by Angle Pin, loose core along the guide runner downslide, top board slowly ejects afterwards, guarantees that by push rod plastic takes out smoothly.During matched moulds, top board resets, and relies on the mold clamping force between moving platen and the solid plate, promotes the slide block return, then moving platen, solid plate, draw between the flitch closed and locked, last loose core of oil cylinder return, and begin a new injection cycle.

The beneficial effects of the utility model are: 1. with slider designs in patrix, make counterdie have only core, guarantee simple in structurely, the placement that helps netting, fixing is especially carried out pre-thermal contraction to screen cloth before the processing, prevents the moulding crumple.2. adopted a patrix, two counterdie productions to overcome the shortcoming of cycle than length.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation at oil cylinder position.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

With reference to Fig. 1, Fig. 2, a kind of filter webs injection mold comprises upper die and lower die, and patrix is a dynamic model, and counterdie is a cover half.Patrix comprises dynamic mould fixing plate 1, draws flitch 2 and moving platen 3, and moving platen 3 is fixing with dynamic mould fixing plate 1.Also be provided with Angle Pin 4 in the patrix, there is slide block 5 in the outside of Angle Pin 4, and slide block 5 leans on mutually with Angle Pin 4.

Counterdie has two, and each counterdie comprises cover half fixed head 6 and solid plate 7, and solid plate 7 is fixed on the cover half fixed head 6, and solid plate 7 is also affixed with the pulling block 8 that is used to spur slide block.Also have core in the counterdie, core is connected with the push rod of an oil cylinder 13.

Draw flitch 2, moving platen 3 and solid plate 7 by guide pillar 9 companies of wearing, an end of guide pillar 9 is a free end, and the other end is fixed on the dynamic mould fixing plate 1.Also be equipped with spacing blind rivet 12 between moving platen 3 and the solid plate 7, guarantee the die sinking distance.

Moving platen 3 surrounds die cavity with solid plate 7, and die cavity has hot flow path to be communicated with it, and top board 10 is arranged in the die cavity, and top board also is provided with push rod 11, and described push rod 11 stretches in the described die cavity.

In the die sinking process, at first loose core by oil cylinder 13, then moving platen 3 separates with drawing flitch 2, to guarantee that stub bar can take out from sprue, moving platen 3 slowly separates with solid plate 7 then, in this process, slide block 5 is under the pulling of pulling block 8 and by Angle Pin 4 guiding, loose core along the guide runner downslide, top board 10 slowly ejects afterwards, guarantees that by push rod 11 plastics take out smoothly.During matched moulds, top board 10 resets, and relies on the mold clamping force between moving platen 3 and the solid plate 7, promotes slide block 5 returns, then moving platen 3, solid plate 7, draw between the flitch 2 closed and locked, last oil cylinder 13 return of loosing core, and begin a new injection cycle.
