Abstract
A transverse internal-thread product demoulding mechanism comprises an upper mouldboard and a lower mouldboard of a mould, wherein the upper mouldboard is connected with a fixed mouldboard, a fixed mould insert is installed in the fixed mouldboard, a mould foot is mounted on the lower mouldboard, a jacking plate is arranged in the mould foot, a jacking rod is connected to the jacking plate, a movable mouldboard is mounted on the mould foot, a movable mould insert is installed in the movable mouldboard, a fashioned product is arranged between the movable mould insert and the fixed mould insert, a section of internal threads is processed on the product, the internal threads are matched with a thread core, a core bar is connected to the tail part of the thread core, an inner wall core of the product is connected to the head part of the thread core, and the core bar is driven to rotate through a hydraulic motor via a driving gear. The transverse internal-thread product demoulding mechanism is characterized in that the core bar is connected with a sliding block, a limit slot is formed in the sliding block, a hydrocylinder is installed on one side wall of the movable mouldboard, and a cylinder pole of the hydrocylinder is connected with the limit slot and drives the core bar on the sliding block to perform core-pulling. The transverse internal-thread product demoulding mechanism overcomes the defect that the thread core is easy to be stuck during the ejection and replacement in the final distance due to inertia, so that products are ejected smoothly and the service lives of components are long.
Description
Technical field
The utility model relates to the horizontal mould emptier of a kind of internal thread goods mould, belongs to the mould of plastics field.
Background technology
Adopt injection moulding (plastics) die production plastic products; The plastic products that for example have female thread structure; Its internal thread demoulding is generally all adopted the transmission of hydraulic motor driven gear to drive action of thread core rotation extraction and is accomplished; But owing to action of inertia, the screw thread of screw thread fuse is easy and die cavity is stuck, causes hydraulic motor to work at the last length section hydraulic motor of extracting out and resetting.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art; Provide a kind of hydraulic motor that adopts to rotate back elder generation extraction screw thread fuse at the inner threaded portion of goods; By the whole slide block of oil cylinder pulling that the parallel extraction goods of whole screw thread fuse are inner then, avoid the dead horizontal mould emptier of internal thread goods mould of thread core subcard.
The technical scheme of the horizontal mould emptier of the utility model internal thread goods mould is: comprise upper mould plate and lower bolster, cope match-plate pattern connects solid plate, and fixed die insert is installed in the solid plate, and the mould pin is installed on the lower bolster; In the mould pin top board is set, connects push rod on the top board, on the mould pin moving platen is installed; Moving die insert is installed in the moving platen, the goods of moulding are arranged between moving die insert and the fixed die insert, goods inside is shaped on one section internal thread; Said internal thread matches with the screw thread fuse, and screw thread fuse afterbody connects core bar, and screw thread fuse head connects goods inwall fuse; Core bar by the hydraulic motor driven rotary, is characterized in that described core bar connects slide block, is shaped on stopper slot in the slide block through travelling gear; On moving platen one sidewall, hydraulic jack is installed, the cylinder rod of hydraulic jack connects stopper slot, and the core bar that drives on the slide block is loosed core.
The horizontal mould emptier of internal thread goods mould of the utility model during the demoulding, at first drives moving platen and solid plate die sinking by injection machine power; After the die sinking, hydraulic motor work drives the core bar rotation through travelling gear; Because the cylinder rod of hydraulic jack is connected in the stopper slot of slide block, stopper slot has certain cushion space, retreats from the internal thread of goods so core bar drives the rotation of screw thread fuse; After the screw thread fuse was deviate from, hydraulic motor quit work, again by hydraulic jack work; The cylinder rod of hydraulic jack just is stuck in the stopper slot, drives slide block and outwards slides, and slide block drives the screw thread fuse and goods inwall fuse integral body is deviate from goods; By push rod goods are ejected outside the mould at last, the demoulding is accomplished.This programme adopts hydraulic motor to take off threaded portion earlier; Utilize hydraulic jack to drive the whole demoulding of fuse again; Avoided the screw thread fuse in the last length section of extracting out and resetting because action of inertia and the easy stuck shortcoming of die cavity make the goods demoulding smooth, the mold component long service life.
The horizontal mould emptier of internal thread goods mould of the utility model is installed bearing between described screw thread fuse and the outer slide, and bearing has been arranged, and the rotation of screw thread fuse smoothly.Be equipped with cylinder bracket on described moving platen one sidewall, hydraulic jack is installed on the cylinder bracket, and is easy for installation, firm.

Fig. 2 is the horizontal mould emptier schematic top plan view of internal thread goods mould of the utility model.
The specific embodiment
The utility model relates to the horizontal mould emptier of a kind of internal thread goods mould, like Fig. 1, shown in Figure 2, comprises upper mould plate 1 and lower bolster 2; Cope match-plate pattern connects solid plate 3, and fixed die insert 4 is installed in the solid plate, and mould pin 5 is installed on the lower bolster; Top board 6 is set in the mould pin, connects push rod 7 on the top board, moving platen 8 is installed on the mould pin; Moving die insert 9 is installed in the moving platen, the goods 10 of moulding are arranged between moving die insert 9 and the fixed die insert 4, goods inside is shaped on one section internal thread 11; Said internal thread 11 matches with screw thread fuse 12, and screw thread fuse afterbody connects core bar 111, and screw thread fuse head connects goods inwall fuse 112; Core bar 111 by hydraulic motor 13 driven rotary, is characterized in that described core bar 111 connects slide block 15, is shaped on stopper slot 151 in the slide block through travelling gear 14; Hydraulic jack 19 is installed on moving platen 8 one sidewalls, and the cylinder rod 16 of hydraulic jack 19 connects stopper slot 151, and the core bar 111 that drives on the slide block 15 is loosed core.During the demoulding, at first drive moving platen 8 and solid plate 3 die sinkings, after the die sinking by injection machine power; Hydraulic motor 13 work drive core bar 111 rotations through travelling gear 14, because the cylinder rod 16 of hydraulic jack 19 is connected in the stopper slot 151 of slide block 15; Stopper slot 151 has certain cushion space, retreats from the internal thread 11 of goods so core bar 111 drives 12 rotations of screw thread fuse, after screw thread fuse 12 is deviate from; Hydraulic motor 13 quits work, and by hydraulic jack 19 work, the cylinder rod 16 of hydraulic jack 19 just is stuck in the stopper slot 151 again; Driving slide block 15 outwards slides; Slide block 15 drives screw thread fuse 12 and goods inwall fuse 112 integral body are deviate from goods, by push rod 7 goods 10 is ejected outside the mould at last, and the demoulding is accomplished.This programme adopts hydraulic motor to take off threaded portion earlier; Utilize hydraulic jack to drive the whole demoulding of fuse again; Avoided the screw thread fuse in the last length section of extracting out and resetting because action of inertia and the easy stuck shortcoming of die cavity make the goods demoulding smooth, the mold component long service life.Bearing 17 is installed between described screw thread fuse 12 and the outer slide 15, bearing has been arranged, the rotation of screw thread fuse smoothly.Be equipped with cylinder bracket 20 on described moving platen 8 one sidewalls, hydraulic jack 19 is installed on the cylinder bracket 20, and is easy for installation, firm.
