Description
Technical field
It the utility model is related to core-pulling mechanism technical field, more particularly to a kind of multiple core-pulling mechanism of mould.
Background technology
Mould is a very important equipment for being molded plastic, is mainly used in moulding plastics product, for some plastics
Product is due to the requirement in its use, and inevitably there is different partings or core pulling, when plastic has, side opening, side be recessed, side
During the shape such as convex, then need to extract out core before die sinking ejection, should reset during matched moulds, this mechanism is referred to as core-pulling mechanism.Tube bundle extracting machine
Configuration formula is a lot, can be divided into hand-operated core pulling and motor-driven core pulling.The same few side cores are needed like pitch, with multiple-threaded screw core pulling.
Number of starts is generally 2-3 heads and promotes side core-pulling eccentric stiffener to extract the motor-driven core-pulling mechanism utilization of side core out with wedge on mould bases is unloaded
The horizontal automatic parting direction oblique chute mechanism of sprocket wheel, chain makes lower mould side parting oblique mechanism make mould side parting, existing
Core-pulling mechanism efficiency is low, when product has in a face many holes to use multiple core-pulling mechanisms when needing processing, and existing machine
Structure is cumbersome when in use, in-convenience in use, it is above-mentioned for solving for this we have proposed a kind of multiple core-pulling mechanism of mould
Problem.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of mould proposed is multiple
Core-pulling mechanism.
To achieve these goals, the utility model employs following technical scheme：
A kind of multiple core-pulling mechanism of mould, including upper die and lower die, the upper mould are located at the lower section of lower mould, the upper mould
Middle part be provided with main operation groove, is provided with main core-pulling device in the main operation groove, the upper end of the main core-pulling device is provided with cylinder,
The main core-pulling device is provided with sliding block, and the upper mould is provided with multiple side operating grooves, and the side operating groove is along main core-pulling device
Circumferential spaced set, be equipped with side core-pulling device, side wall of the side core-pulling device close to upper end in the side operating groove
On be equipped with limited block, the lower end of the side core-pulling device is equipped with into son, and the upper center of the lower mould is provided with positioning hole.
Preferably, the lower end of the lower mould is provided with leg, the quantity of the leg for four, and leg is distributed in lower mould
Lower end corner.
Preferably, the side core-pulling device is to be obliquely installed.
Preferably, the quantity of the side core-pulling device is four.
Preferably, it is provided with lead between the main core-pulling device and cylinder.
The utility model uses multiple core pulling technology, some complicated products can be smoothly stripped and realize volume production, and it is certainly
Dynamicization degree is high, goes out that mold process is simple, and main core-pulling mechanism and side core-pulling mechanism can together be extracted out with upper mould, shorten die sinking
Time, mould production cost is reduced, the utility model is simple in construction, reasonable in design, can be with large-scale promotion.
