Abstract

The utility model discloses a kind of low pressure injection moulds of improved pneumatic press, including die body, the Pneumatic module being mounted on die body, are equipped with a forming cavity in die body, which connects with the intracorporal forming runner of mould;The root Pneumatic extension body of rod is equipped in die body, the Pneumatic extension body of rod includes the chamber of a sealing, is placed in sealed chamber, and one end of the close-fitting body of rod of cavity wall with sealed chamber, the body of rod can be inserted into forming cavity;A forming block is installed on one end in body of rod insertion forming cavity;The utility model structure is simple, and design rationally, is very suitable for the injection molding of the injection mold and the moulding with class pulled core structure of small size.

Description

A kind of low pressure injection mould of improved pneumatic press
Technical field
The utility model relates to a kind of low pressure injection mould, specifically a kind of low-pressure injection molding of improved pneumatic press Mold.
Background technique
Low pressure injection mould refers to the lower injection mold of injection pressure, in actual production process, low pressure injection mould Tool is also required to often have pulled core structure, from the block or bar of the inward-facing movable press of mold, is realized using bar or jacking block Moulding to liquid plastic cement.It is often realized, that is, is utilized using mechanical structure in the structure of existing such bar or the block of press Motor or other linkage mechanisms realize the telescopic movable of block or bar, no matter since linkage mechanism or motor mechanism are in control It is complex or in structure and also larger in volume, the needs of actual use are not well positioned to meet, especially For the fine jack of small size mold, there can be biggish deficiency in volume using mechanical structure.
Utility model content
The purpose of the utility model is to overcome deficiencies of the prior art, provide a kind of utilize and pneumatically realize press The low pressure injection mould that the type of correcting one's mistakes of telescopic movable pneumatically presses.
To achieve the above object, the technical scheme adopted by the utility model is a kind of low pressure of improved pneumatic press Injection mold is equipped with a forming cavity, the forming cavity and die body in die body including die body, the Pneumatic module being mounted on die body An interior forming runner connects;The root Pneumatic extension body of rod is equipped in die body, the Pneumatic extension body of rod includes the chamber of a sealing, peace The close-fitting body of rod of cavity wall in sealed chamber, with sealed chamber is set, one end of the body of rod can be inserted into forming cavity;Body of rod insertion One forming block is installed on one end in forming cavity;Notch compatible with forming block is offered in the cavity wall of forming cavity, often Block is shaped under rule state to seal notch;Sealed chamber connects with the intracorporal air flow channel of mould, which passes through Pipeline connects with Pneumatic module;Pneumatic module is equipped with a controller, provides just for controlling Pneumatic module sealed chamber Pressure or negative pressure.
When the utility model is implemented, the stretching motion of the body of rod is realized using the positive pressure or negative pressure of single air flow channel, into And realize the stretching motion of forming block, it completes injection molded and moulding is processed.
The utility model structure is simple, and design rationally, is very suitable for the injection mold of small size and with class core pulling knot The injection molding of the moulding of structure.
Detailed description of the invention
Fig. 1 is this practical new structural schematic diagram.
Specific embodiment
For convenience of being further understood to the utility model, embodiment is enumerated now in conjunction with attached drawing, the utility model is made Further instruction.
Embodiment:
As shown in Figure 1, the utility model includes die body 1, the Pneumatic module being mounted on die body 12, one is equipped in die body 1 A forming cavity 3, the forming cavity 3 connect with a forming runner 4 in die body 1;The root Pneumatic extension body of rod 5, gas are equipped in die body 1 The dynamic flexible body of rod 5 includes the chamber of a sealing, is placed in sealed chamber, the close-fitting body of rod of cavity wall with sealed chamber, bar One end of body can be inserted into forming cavity 3;A forming block is installed on one end in body of rod insertion forming cavity 3;The chamber of forming cavity 3 Notch compatible with forming block is offered on wall, forming block can seal notch under conventional sense;In sealed chamber and die body 1 An air flow channel 6 connect, which is connected with Pneumatic module 2 by pipeline;Pneumatic module 2 is equipped with a control Device processed provides positive pressure or negative pressure to sealed chamber for controlling Pneumatic module 2.
