Description
Technical field
The invention belongs to plastic molding machine technical field, and in particular to a kind of folding mould of plastic product molding machine
Device.
Background technology
Above mentioned plastic products refer mainly to but are not definitely limited to refer to hollow plastic product, and hollow plastic product is as respectively
Plant plastic containers, stacking bucket or even pallet（Pallet such as CN102407967B, CN103253442A and CN102009774B）, etc.
Deng.
As is known in the industry, plastic product molding machine is often molded a product and just needs once to be opened mould assembling action, can to this
With referring to CN2481510Y（The improved mould opening-closing mechanism of structure）、CN2481511Y（Mould opening-closing mechanism）、CN101890772B
（Mould opening-closing mechanism）、CN101890805B（The magnetic mold closing device of hollow plastic product molding machine）、CN102357948A（Embrace
Elbow formula clasp mould mechanism）、CN102848558B（The clamping apparatus of hollow plastic product molding machine）、CN103522528B（Blowing
The Horizontal matched mould machine structure of shaping）、CN103587109B（The clamping apparatus of hollow plastic product molding machine）With
CN103538244B（The clamping apparatus structure of hollow plastic product molding machine）, etc..
The common feature for being not limited to folding mould device disclosed in patent document exemplified above is to make mould using oil cylinder
Frame carries that the mould being arranged on mutually closes up or reprimand is opened each other, thus exist open closure pressing speed it is slow fast and influence plastic products into
Type efficiency, need to be equipped with corresponding Mode-locking oil cylinder and hydraulic power supply to cause complex structure and lose cheap be the logical of aforementioned patent
Disadvantage.
Drive a pair of mould bases together with the opposite displacement of mould on mould bases by motor or reprimand is opened i.e. by motor conduct each other
Direct driving force realizes that folding mould can largely make up foregoing logical disadvantage.And it is visible in disclosed Chinese patent literature
All motors drive the technical information of folding mould device, typical such as Authorization Notice No. CN202097949U（A kind of motor drives and opens
Clamping）And CN202053507U（Motor-driven die opening/closing mechanism）Although this two patents can each cash its explanation
Technique effect described in book technique effect column, but complex structure is its shortcoming, it is especially, another because being needed without locked mode function
Row sets booster body（Reference can be made to the 0029th section of two patent specifications）, it is then relatively terse and be for designing structure
The folding mould device of the plastic product molding machine of motor direct-drive does not simultaneously have referential technical inspiration.
For above-mentioned prior art, the applicant has made lasting and beneficial exploration, forms finally and will be described below
Technical scheme and the equipment test center in the case where secrecy provision is taken in the applicant is simulated experiment, as a result demonstrate,prove
Bright is practicable.

653, offer a wind spring pin positioning embeded groove 662 on the outer wall of foregoing wind spring pin positioning shaft sleeve 66, one end of aforesaid roll 651 with
And the other end is respectively formed with a wind spring pin, the one of wind spring in the wind spring pin of one end and one group of volume Huang pin adjustment caulking groove 653
The pin adjustment scarf of caulking groove 653, and the wind spring pin of the other end and the scarf of wind spring pin positioning embeded groove 662, change one end of wind spring 651
Wind spring pin setting position and can change the pretightning force of wind spring 651 on one group of wind spring pin adjustment caulking groove 653.
In the present embodiment, foregoing motor 61 is the motor with positive and negative rotating function.
According to professional general knowledge, under actual use state, it is provided with towards the side for moving to right mould bases 3 mould bases 2 is moved to left
Left half module for molding plastic products, right half module, left and right half are provided with mould bases 3 is moved to right towards the side for moving to left mould bases 2
Mould is mutually corresponded to.
When matched moulds is wanted, motor 61 works counterclockwise, reduction box 62 is driven by motor 61, by reduction box power output shaft 21
Drive shaft 64 is driven, wind spring pin positioning shaft sleeve 66 and stop collar 67 are driven by drive shaft 64, by wind spring pin positioning shaft sleeve 66 pairs
Wind spring 651 is rolled tightly, and wind spring case 65 still remains static before wind spring 651 is not rolled tightly, and only after wind spring 651 is rolled tightly
The rotate counterclockwise of wind spring case 65 is driven by wind spring 651.Wind spring case shifting block in wind spring 65 rotate counterclockwise of case by being secured to
69 drive guide block 631, the right-hand member for making swing arm 63 by guide block 631 to move upwards, and the left adjustment connector 681 of pull bar is driven by swing arm 63
Corresponding sports, until making pull bar 68 support to horizontality.In this condition, the lower end phase mutual exclusion of left and right arm 4,5 open i.e. towards
Direction displacement away from one another, and the upper end of left and right arm 4,5 then swings in opposite directions, forces left and right shifting formwork frame 2,3 to follow shifting formwork frame
Rail plate 12 slides in opposite directions, completes mould assembling action.
After completing mould assembling action, motor 61 works on, and drives spacing collar 67 to continue to turn by drive shaft in said process 64
It is dynamic, when the limited block 671 of spacing collar 67 suffers the i.e. limited block 671 and the one of breach 65221 when stopping of the end wall of breach 65221
Individual end wall（Also end face can be claimed）During contact, then show that drive shaft 64 rotate in place, so as to complete locked mode.
