Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a hob mould, includes mould 1, lower mould 2 and side core pulling mechanism 3, because this product is the plastic bag hardware, need put into injection moulding behind the hardware on the mould during moulding plastics, the difficult point of mould lies in the location problem of hardware on the mould, and this design utilizes the hardware to block from the step in area earlier under the mould die sinking state and realizes first location, then carries out the secondary through side core pulling mechanism 3 and fixes, then accomplishes injection moulding, side core pulling mechanism 3 fixes respectively at the both ends of last mould 1 and

lower mould

2, 2 inside hardware 4 that are provided with of lower mould, the shaping is accomplished as the core to hardware 4.

The side core-pulling mechanism 3 comprises a first side core-pulling mechanism 5 and a second side core-pulling mechanism 6, the first side core-pulling mechanism 5 is fixedly connected with one end of the lower die 2, and the second side core-pulling mechanism 6 is fixedly connected with one end of the lower die 2, which is far away from the first side core-pulling mechanism 5.

First side 5 of loosing core includes first hydro-cylinder 7, first slider 8 and

slide wedge

9, 2 upper surface fixed mounting of lower mould has first guide block 10, and first guide block 10 is provided with two sets ofly, 8 upper surface sliding connection on first slider 8 lower surface and the

lower mould

2, 8 both sides upper surface of first slider and 10 lower surface sliding connection of first guide block, the side surface fixed mounting of first hydro-cylinder 7 and lower mould 2, the output and the 8 joints of first hydro-cylinder 7, the upper surface of slide wedge 9 and the lower fixed surface installation of last mould 1, the lower surface and the 8 sliding connection of first slider of slide wedge 9.

The specific implementation mode is as follows: first guide block 10 is in the both sides of first slider 8, first guide block 10 is installed on lower mould 2, and the marginal portion surpasss the edge of mould, first guide block 10 has formed the guide rail with lower mould 2, first slider 8 slides on it, because need put into hardware 4 during the die sinking, consequently need first slider 8 backspace, drive its motion by first hydro-cylinder 7 and the joint of first slider 8, because first slider 8 need act as the location and use, need decide before the compound die finishes, consequently fixed connection slide wedge 9 on last mould 1, when going up mould 1 and moving to lower mould 2, the angle of inclination on the slide wedge 9 slides with the angle of inclination of first slider 8, make first slider 8 move to hardware 4 direction.

The second side 6 of loosing core includes installation piece 11, second hydro-cylinder 12 and stopper 13, the one end fixed mounting that first guide block 10 was kept away from to lower mould 2 has second guide block 14, the surface of installation piece 11 and the lower surface sliding connection of 2 upper surfaces of lower mould and second guide block 14, the fixed surface installation of stopper 13 lower mould 2, second hydro-cylinder 12 and stopper 13 fixed mounting, second hydro-cylinder 12 and installation piece 11 joint.

The mounting block 11 is fixedly provided with a second slide block 15.

The specific implementation mode is as follows: because hardware 4 is a cylinder, when first slider 8 reaches the locating position, the hardware still exists and moves to second side 6 directions of loosing core, consequently, need second side location of loosing core after first side 5 location of loosing core, and the restriction of mould itself can't use the slide wedge to make its motion, just use second hydro-cylinder 12 to push and stimulate it, have two second slider 15 on the installation piece 11 to fix a position hardware 4 ground opposite side, installation piece 11 moves under second guide block 14 like first slider 8, stopper 13 restriction installation piece 11's the position of retreating, and install second hydro-cylinder 12 on a stopper 13 in the middle.

The working principle is as follows: at first place the mould benevolence of mould with hardware 4 in, because there is the step in hardware 4's one end, consequently this step can play the positioning action in proper order in mould benevolence by the card, then the compound die, slide wedge 9 is along with last mould 1 motion, drive first slider to hardware 4 motion, carry out the secondary location, the other end then promotes the motion of installation piece 11 by second hydro-cylinder 12, and make the secondary location of this one end of second slider 15 completion, then carry out injection moulding, after the shaping, both ends all are driven the slider by the hydro-cylinder and are removed.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
