Abstract

Disclosed is a plastic chair mold stripping mechanism. The mechanism comprises a die cavity, a moving mold and a die core, wherein a mold cavity is formed among the die cavity, the moving mold and the die core; a pouring gate and a hot runner are arranged in the die cavity; the mouth of the hot runner is provided with a hot runner plate and a hot runner pressing plate; and a positioning ring is arranged in the hot runner pressing plate. The mechanism is characterized in that an oil cylinder is arranged in the die core; a jacking block is arranged in the mold cavity, an oil filling hole of the oil cylinder is matched with the jacking block; a pouring gate insert is arranged in the die core and is matched with a hot runner nozzle in an inclined plane way; and the jacking block is contacted with the pouring gate insert. In the scheme, the product is reliable as the oil cylinder is adopted for injecting out; the pouring gate can prune automatically; the injected product does not need to be pruned artificially; and the pouring gate insert is matched with the hot runner nozzle in an inclined plane way, therefore, accurate match is realized in each action, the leakage glue is less, and the product obsolescence rate is low.

Description

Plastic chair mould hull and pulp removing machine structure
Technical field
The utility model relates to the Plastic chair mould, and the mould especially for making bigger daily Plastic chair for example relates to the king-sized product of wall thickness, belongs to the mould of plastics field.
Background technology
Plastic chair is a kind of daily living article, and Plastic chair is an overall structure, the shape more complicated, and about 3mm, it is relatively low to exist intensity substantially for the wall thickness of conventional Plastic chair, shortcomings such as easy damage.Can satisfy requirements such as high strength in order to change product, need design wall thickness, the highest wall thickness of product is the chair of 30mm.When the product wall thickness is big, injection moulding cooling needs the long especially time just can reach demoulding requirement, and prior art can adopt the gas assistant formation, suspends to eject etc. outside the technology, does not have better way.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of technical scheme of simple possible to be provided, adopt cast gate to prune automatically, being applicable to the Plastic chair mould hull and pulp removing machine structure of wall thickness.
The technical scheme of the utility model Plastic chair mould hull and pulp removing machine structure is: comprise die cavity, dynamic model and core, between die cavity, dynamic model and core, form die cavity, in die cavity, be shaped on cast gate and hot flow path, hot runner manifold and hot flow path pressing plate are installed in the hot-fluid road junction, in the hot flow path pressing plate centring ring is arranged, it is characterized in that in the described core oil cylinder being installed, angled slide block is installed in the die cavity, the oil filler point of oil cylinder matches with angled slide block, gating insert is installed in core, gating insert cooperates as the inclined-plane with hot-runner nozzle, and angled slide block contacts with gating insert.
Plastic chair mould hull and pulp removing machine structure of the present utility model, die cavity and dynamic model break away from after the die sinking, but core is stayed a side of die cavity, and dynamic model continues die sinking, makes the ejecting apart from adequate prod of it and die cavity.But this moment, product was still stayed in the core, need eject product with angled slide block, cylinder action, drive angled slide block and eject product along the movement locus of setting, cast gate ejects with product and excision automatically, and product breaks away from mould, a circulation is finished in the manipulator pickup.Gating insert is installed in core, and gating insert cooperates as the inclined-plane with hot-runner nozzle, all requires to repeat accurate cooperation when moving at every turn, causes product rejection rate to improve in order to avoid produce leakage glue.This programme adopts the product oil cylinder to eject reliably, and cast gate is pruned automatically, and ejecting the back product, no longer to need the people be manual pruning, adopts gating insert to cooperate as the inclined-plane with hot-runner nozzle, and each action is accurately cooperated, and leakage glue is few, and product rejection rate is low.
Plastic chair mould hull and pulp removing machine structure of the present utility model is installed locating piece on its dynamic model, and locating piece matches with core, guarantees the reliability of resetting, and locating piece can also guarantee the accuracy of parting line simultaneously, guarantees product quality.On the die cavity of its oil cylinder one side column is installed, is avoided oil cylinder to be collided.Hydraulic jack is installed in dynamic model, and hydraulic jack connects core, and core can eject product again by hydraulic jack.
Description of drawings
Fig. 1 is the A-A schematic cross-section of Fig. 2;
Fig. 2 is the utility model Plastic chair mould hull and pulp removing machine structure front elevational schematic.
The specific embodiment
The utility model relates to Plastic chair mould hull and pulp removing machine structure, as Fig. 1, shown in Figure 2, comprise die cavity 1, dynamic model 11 and core 8, at die cavity, form die cavity between dynamic model and the core, in die cavity 1, be shaped on cast gate 31 and hot flow path 21, hot runner manifold 2 and hot flow path pressing plate 4 are installed in the hot-fluid road junction, centring ring 3 is arranged in the hot flow path pressing plate 4, it is characterized in that installing in the described core 8 oil cylinder 6, angled slide block 10 is installed in the die cavity, and the oil filler point 61 of oil cylinder 6 matches with angled slide block 10, and gating insert 9 is installed in the core 8, gating insert 9 and hot-runner nozzle 22 cooperate as the inclined-plane, and angled slide block 10 contacts with gating insert 9.Die cavity 1 and dynamic model 11 breaks away from after the die sinking, but core 8 is stayed a side of die cavity 1, and dynamic model 11 continues die sinkings, makes the ejecting apart from adequate prod of it and die cavity 1.But this moment, product was still stayed in the core 8, need eject product with angled slide block 10, oil cylinder 6 actions, drive angled slide block 10 and eject product along the movement locus of setting, cast gate ejects with product and excision automatically, and product breaks away from mould, a circulation is finished in the manipulator pickup.Gating insert 9 is installed in core 8, and gating insert 9 and hot-runner nozzle 22 cooperate as the inclined-plane, all require to repeat accurate cooperation when moving at every turn, cause the product rejection rate raising in order to avoid produce leakage glue.This programme adopts the product oil cylinder to eject reliably, and cast gate is pruned automatically, and ejecting the back product, no longer to need the people be manual pruning, adopts gating insert to cooperate as the inclined-plane with hot-runner nozzle, and each action is accurately cooperated, and leakage glue is few, and product rejection rate is low.Locating piece 7 is installed on its dynamic model 11, and locating piece 7 matches with core 8, guarantees the reliability of resetting, and locating piece can also guarantee the accuracy of parting line simultaneously, guarantees product quality.Column 5 is installed on the die cavity 1 of its oil cylinder 6 one sides, is avoided oil cylinder to be collided.Hydraulic jack 12 is installed in its dynamic model 11, and hydraulic jack 12 connects core 8, and core can eject product again by hydraulic jack.
