Description
Technical field
The utility model relates to the injection mold of infusion bottle, particularly a kind of locked mode supercharging device based on PP transfusion bottle base mould.
Background technology
The injection moulding quality of infusion bottle and Design of Dies and manufacture have substantial connection, the success or failure of infusion bottle processing, depend on Design of Dies effect and Making mold quality to a great extent, and the structural element that Design of Dies will be considered have following some: 1, die joint: the contact surface that when namely mould closes, die and punch cooperatively interact, its position and the selected of form, affect by factors such as article shape and outward appearance, wall thickness, forming method, after-processing technology, mould-type and structure, release method and shaping machine structures; 2, running gate system: namely by the feeding-passage between injection machine nozzle to die cavity, comprise sprue, runner, cast gate and cold slug well, particularly the selected win of gate location is conducive to molten plastic is full of die cavity under good flow state, and to be attached on goods solid-state is left to and is easy to eject in mould with cast gate cold burden and is removed (except hot runner mould) when die sinking; 3, clamp force: when mould matched moulds, the size of clamp force decides die joint and whether can produce the defect such as overlap, burr, and this directly affects the quality of PP infusion bottle.
Existing for mould matched moulds many employings hydraulic mould-matching structure, its matched moulds is steady, little to mould impulsive force, but there is the little defect of clamp force, and even when hydraulic oil occurs to leak, mould cannot complete self-locking, causes product waster rate straight line to raise.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of and increases clamp force, guarantees mould self-locking and the low locked mode supercharging device based on PP transfusion bottle base mould of improvement cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of locked mode supercharging device based on PP transfusion bottle base mould, it comprises mould shifting oil cylinder, pressurizing cylinder, moving platen, interior core and outside core, pressurizing cylinder is installed on the afterbody of mould shifting oil cylinder, the output shaft of pressurizing cylinder stretches into the inside of mould shifting oil cylinder, and extrude the hydraulic oil of mould shifting oil cylinder afterbody, the output shaft head of mould shifting oil cylinder and moving platen are fixedly linked, interior core is installed on the downside of moving platen, core cover is set in outside interior core, the front end of interior core coordinates with outside core, the downside of outside core is also provided with cast gate die, interior core, outside core and cast gate die complement each other to form bottle base die cavity.
Described inner mold core inner is provided with cooling duct vertically.
The utility model has the following advantages:
1, pressurizing cylinder is set at mould shifting oil cylinder afterbody, the afterbody hydraulic oil of pressurizing cylinder to mould shifting oil cylinder is exerted pressure, increase clamp force, simultaneously when mould shifting oil cylinder generation hydraulic fluid leak, pressurizing cylinder affords redress pressure, guarantee mould self-locking, the probability that bottle base produces the defect such as overlap, burr is little, and yields is high.
2, install pressurizing cylinder additional at original mould shifting oil cylinder afterbody, repacking cost is low, and reliability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-mould shifting oil cylinder, 2-pressurizing cylinder, 3-moving platen, core in 4-, 5-core cover, 6-outside core, 7-cast gate die, 8-cooling duct.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of locked mode supercharging device based on PP transfusion bottle base mould, it comprises mould shifting oil cylinder 1, pressurizing cylinder 2, moving platen 3, interior core 4 and outside core 6, pressurizing cylinder 2 is installed on the afterbody of mould shifting oil cylinder 1, the output shaft of pressurizing cylinder 2 stretches into the inside of mould shifting oil cylinder 1, and extrude the hydraulic oil of mould shifting oil cylinder 1 afterbody, output shaft head and the moving platen 3 of mould shifting oil cylinder 1 are fixedly linked, interior core 4 is installed on the downside of moving platen 3, core cover 5 is set in outside interior core 4, the front end of interior core 4 coordinates with outside core 6, the downside of outside core 6 is also provided with cast gate die 7, interior core 4, outside core 6 and cast gate die 7 complement each other to form bottle base die cavity.
Further, described interior core 4 inside is provided with cooling duct 8 vertically, and in injection moulding process, after being cast, after passing into cooling water to inside, cooling duct 8, bottle base is soon shaping, enhances productivity, the temperature of core 4 in simultaneously reducing fast.
The course of work of the present utility model is as follows: mould shifting oil cylinder 1 rear end oil-feed, front end is fuel-displaced, drive moving platen 3 successively, interior core 4 moves down, core 4 and outside core 5 matched moulds in realizing, and coordinate with cast gate die 7 and form bottle base die cavity, pressurizing cylinder 2 rear end oil-feed, front end is fuel-displaced, output shaft moves down, and extrude the hydraulic oil of mould shifting oil cylinder 1 afterbody, realize supercharging, improve the mold clamping force of mould, guarantee mould self-locking simultaneously, overlap is there is to prevent product, the defects such as burr, injection mould blank in bottle base die cavity, after cast, by passing into cooling water to inside, cooling duct 8, accelerate bottle base cooling velocity, enhance productivity.After shaping, pressurizing cylinder 2 end oil outlet, front end oil-feed, pressure release, moves after output shaft, and the hydraulic oil of mould shifting oil cylinder 1 afterbody is stressed reduction, simultaneously mould shifting oil cylinder 1 end oil outlet, front end oil-feed, drives moving platen 3 successively, interior core 4 exits outside core 5, realize parting.
