Abstract

The utility model discloses a forming mould head of the extrusion molding machine. A group of feed inlets are arranged at the circumference of the lateral side. The interior side is installed with a molding mound core that works in with the feed inlet. The feed inlet and the molding core are positioned inside the forming molding group axially by sequence. The core mould core is positioned at the central axle of all the forming mold cores. The orderly axial arrangement of a plurality of forming mold cores inside the mold head can form a number of mold cavities, which work in with the feed inlets to pour in different formative materials. The plastic tubes out of extrusion are multi-layer compound tube. Because of the arrangement of the structure, the user can shut down different injection equipments to produce different multi-layer plastic tubes according to the specific needs of the user.

Description

The single lead screw ex truding briquetting machine molding die

Technical field

The utility model relates to a kind of single lead screw ex truding briquetting machine molding die that is applied to moulding MULTILAYER COMPOSITE flexible pipe.

Background technology

Many cosmetics of Xiao Shouing in the market, commodity such as mildy wash and toothpaste all use plastic flexible pipe to pack, adopt the plastic flexible pipe packing to compare with packing containers such as early stage metal hose or vials, have in light weight, cost is low, pollution-free, save the advantage of a large amount of metals resources, but individual layer or double-layer plastic flexible pipe commonly used on the market at present, mainly there is poorly sealed shortcoming in it, make the shelf-life of content product in the pipe shorter, and the general material that its content mostly is simpler and easy or smell is lighter then easily makes the rotten of this material and lost efficacy if fill the denseer material of smell.

Adopt the flexible pipe of MULTILAYER COMPOSITE, can improve the waiting time of content effectively, but the manufacturing of plastic flexible pipe is mainly produced by the plastics single lead screw ex truding briquetting machine, existing plastics single lead screw ex truding briquetting machine mostly can only be produced the individual layer or double-deck plastic flexible pipe, this can not satisfy the needs in market, but therefore needs to develop a kind of single lead screw ex truding briquetting machine of production MULTILAYER COMPOSITE flexible pipe to satisfy the needs in market.

The utility model content

The purpose of this utility model just provides a kind of single lead screw ex truding briquetting machine molding die of production MULTILAYER COMPOSITE flexible pipe.

For achieving the above object, solution of the present utility model is: a kind of single lead screw ex truding briquetting machine molding die, its outer circumference is provided with one group of feeding mouth, its inside is provided with the formation die core that matches with feeding mouth, feeding mouth and formation die core axially are located in the moulding module in regular turn, and a main core rod is to be positioned on each formation die core central shaft.

Described one group of feeding mouth and formation die core are set to five.

Described feeding mouth outside is provided with the pan feeding flange.

After adopting such scheme, the axial in regular turn setting of a plurality of formation die cores in the utility model molding die, can form a plurality of die cavitys, cooperate feeding mouth with matching, inject different molding materials, be the MULTILAYER COMPOSITE flexible pipe by the plastic flexible pipe that come out of extruding because the setting of this structure, the dealer can be according to needs the corresponding feeding mouth of shutoff can obtain the plastic flexible pipe of the different numbers of plies.

The specific embodiment

Please as shown in Figure 1, 2, single lead screw ex truding briquetting machine die head 2 profiles of the present utility model are cylindrical, and it mainly is made up of preceding outer die casing 21, back outer die casing 22, outer core rod 23, outer stick core rod 24, barrier layer core rod 25, internal layer stick core rod 26, internal layer core rod 27, main core rod 28, discharging axle core 29, discharging axle core retainer plate 30; Before outer die casing 21 and back outer die casing 22 form the cylinder of an axial hollow, this cylinder front portion wears discharging axle center 29, the front end of the preceding outer die casing 21 that discharging axle core retainer plate 30 is socketed on the circumference in discharging axle center 29 and fixes by a discharging axle core fixed cover 301; This cylindrical rear portion wear main core rod 28 through after outer die casing 22 in preceding outer die casing 21, link with discharging axle core 29; The outer core rod 23 of socket, outer stick core rod 24, barrier layer core rod 25, internal layer stick core rod 26 and internal layer core rod 27 successively in the annular space that preceding outer die casing 21, back outer die casing 22 and discharging

axle core

29,30 assemblings of main core rod form; Form shaping mold cavity 231,241,251,261,271 between each

core rod

23,24,25,26,27 and discharging axle core 29 and the main core rod 28.

Preceding outer die casing 21, outer core rod 23, outer stick core rod 24, barrier layer core rod 25, be formed with pan feeding passage 232 respectively behind internal layer stick core rod 26 and internal layer core rod 27 fits, 242,252,262,272 with on preceding outer die casing 21 and back outer die casing 22, offer and the corresponding feeding mouth 233 of each pan feeding passage, 243,253,263,273 communicate, each feeding mouth 233,243,253,263,273 outsides are equipped with pan feeding flange 234,244,254,264,274, wherein the pan feeding flange 234,254,274 peripheries in preceding outer die casing 21 and back outer die casing 22 formation become axially arranged in a straight line, pan feeding flange 244,264 with aforementioned arranged in a straight line become 90 degree axially on arranged in a straight line; Pan feeding flange 244 is connected a tripper 31 jointly with 264.
