Background

In the assembly of a mold, the mold core needs to be fixed by screws, and the mold core is tightly matched with the opening frame of the mold blank and is not easy to disassemble and assemble, so that the mold plate is erected firstly when the mold core needs to be disassembled, the mold core is knocked out from the back of the mold plate by using a long screw, the mold blank drops and the threads of the mold core are damaged in the knocking process, and when the mold is produced on an injection molding machine, the whole mold needs to be disassembled, the disassembling and assembling waste time and the production efficiency are influenced.

At present, the common screw is used for directly removing the die, however, the force application point of the mode is not at the center of the screw, time and labor are wasted during die removing, the thread part is easy to damage, workers' hands are easy to crush, potential safety hazards exist, the mode is not favorable for maintenance and replacement in the production process, some die removing are carried out by means of the drawing device, but the screw part of the front section of the existing drawing device cannot be replaced, the drawing structure at the back is complex, when the die core uses screws of different models, a plurality of sets of detaching tools are required to be frequently replaced, and the whole die removing process can be completed.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model discloses an it is not enough to prior art, provides a removable form removal device, this utility model structure is simple, makes things convenient for the installation and the dismantlement of mould, and the operation is safer, more saves time.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a removable form removal device, includes the pull rod, draws the hammer, its characterized in that, still includes the connecting seat, draws the screw, draw the hammer cover and establish on the pull rod, and draw hammer and pull rod sliding connection, the fixed nut that is equipped with of one end of pull rod, the other end is detachable is connected with the connecting seat, the connecting seat with draw screwed connection.

Furthermore, the drawing hammer is in a dumbbell-shaped structure with two wide ends and a narrow middle part.

Further, the outer diameter of the nut is larger than the inner diameter of the drawing hammer.

Further, the upper end and the lower extreme of connecting seat are the cylinder, and upper end cylinder diameter is less than lower extreme cylinder diameter, upper end cylinder and lower extreme cylinder integrated into one piece.

Furthermore, the cylinder at the upper end of the connecting seat is provided with a thread connected with the pull rod thread along the direction of the central shaft.

Further, the lower extreme of connecting seat is provided with and draws the draw-in groove of screw upper end joint.

Furthermore, the lower end of the drawing screw is provided with a thread matched with the threaded hole of the mold core.

The utility model has the advantages that: the utility model is designed into a dumbbell-shaped structure, which prevents the drawing hammer from falling off from the hand when the drawing hammer is held by the hand to slide up and down to provide power source, thus ensuring the operation process to be safer; the die core and the drawing screw are locked by the screw, so that the assembly process is safer and the assembly and disassembly are more convenient; the front mold core on the injection molding machine can be replaced under the condition of not taking off the machine, so that the production efficiency is improved; the connecting seats of different types are matched with the drawing screws, and can correspond to mold cores of different types.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and 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.

As shown in fig. 1, a removable form removal device, includes pull rod 1, draws hammer 2, connecting seat 3, draws screw 4, draw hammer 2 cover and establish on pull rod 1, and draw hammer 2 and pull rod 1 sliding connection, the fixed nut 5 that is equipped with of one end of pull rod 1, the other end is detachable is connected with connecting seat 3, connecting seat 3 with draw the screw 4 and connect.

Specifically, the pull rod 1 is a commercially available bolt standard.

Specifically, the drawing hammer 2 is in a dumbbell-shaped structure with two wide ends and a narrow middle part.

Specifically, draw hammer 2 and slide from top to bottom between nut 5 and the connecting seat 3 on pull rod 1, provide the power source, just the external diameter of nut 5 is greater than draw hammer 2's internal diameter prevents to draw hammer 2 and breaks away from pull rod 1 when moving from top to bottom.

Specifically, the upper end and the lower extreme of connecting seat 3 are the cylinder, and in order to make the overall device light, the diameter of upper end cylinder is less than lower extreme cylinder diameter, and upper end cylinder and lower extreme cylinder along same the central axis integrated into one piece, the upper end cylinder be equipped with along the center pin direction with 1 threaded connection's of pull rod screw thread.

Specifically, the connecting seat 3 has different specifications, and the lower end cylinder of the connecting seat 3 is provided with different clamping grooves matched with the drawing screws 4. The connecting seats and the drawing screws of different specifications are matched with each other and can correspond to different die core screw holes.
