The mold core part can be slowly ejected out of the mold plate through the push-out structure, the flash between the through hole and the mold core is cleaned, and the problem that the mold core is knocked to be completely separated from the through hole of the mold plate and damaged by using a hammer and a rubber rod is solved.

Description

Connecting structure of template and mold core

Technical Field

The utility model relates to a connecting structure of a template and a mold core, and belongs to the technical field of molds.

Background

When two rubber section bar joints are subjected to hot-press butt joint forming by using a rubber joint die, in order to increase friction of the two joints on a template and effectively prevent the two joints from moving, or in order to enable the two joints to form required shapes on the template, a core 2 piece is required to be installed on the template 1 at the position corresponding to the two joints, and the core 2 piece can be seen in fig. 1.

The technology of installation core 2 on present template 1, be at template 1 relative two through-holes that set up, two cores 2 are corresponding to be installed in two through-holes, because can produce some flashes and get into in the through-hole of core 2 and template 1 when carrying out hot pressing butt joint shaping, need untimely ejecting the core 2 from the through-hole of template 1 and clear up the flash, need use hammer and rubber rod to knock out core 2 from the through-hole of template 1, when knocking out, the dynamics of knocking out is difficult to control, in case knock the dynamics too big will lead to the core 2 directly to deviate from the through-hole of template 1 completely, lead to the core 2 to damage.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a connecting structure of a template and a mold core.

The utility model is realized by the following technical scheme.

The utility model provides a connecting structure of a template and a core, which comprises:

the template and with the core through the through-hole cooperation installation of setting in the template, there is the structure of releasing on the template of the bottom side of through-hole and contradicts with the core bottom, realize the core slowly ejecting in the template.

The push-out structure comprises a threaded hole arranged on the side template at the bottom of the through hole, the threaded hole is partially formed in the template, and the unformed part of the threaded hole corresponds to the bottom of the mold core; the mold core is characterized by further comprising a screw screwed in the threaded hole, and the bottom of the screw is abutted against the bottom of the mold core through an unformed part of the threaded hole so as to form a push-out structure.

Three quarters of the threaded holes are formed in the template, and the unformed part of one quarter of the threaded holes corresponds to the bottom of the mold core.

The core and the through hole are matched in a square shape.

The outer side of the top of the screw is hexagonal, so that the screw can be screwed in and out in the threaded hole conveniently by using the internal hexagonal cylinder.

And the template positioned at the end part of the threaded hole is provided with a counter bore section for accommodating the hexagonal section outside the screw.

The hexagonal section outside the holding screw is internally provided with a hexagonal groove, so that the outer hexagonal wrench convenient to use can be screwed.

The accommodating screws positioned on the side edges of the hexagonal grooves are provided with straight grooves, so that the accommodating screws can be conveniently operated through straight screwdrivers.

The utility model has the beneficial effects that: the mold core part can be slowly ejected out of the mold plate through the push-out structure, the flash between the through hole and the mold core is cleaned, and the problem that the mold core is knocked to be completely separated from the through hole of the mold plate and damaged by using a hammer and a rubber rod is solved.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1-3.

The utility model relates to a connecting structure of a template and a mold core, which comprises:

providing a template 1 of a rigid installation foundation, wherein the template 1 is provided with square through holes 11, and the through holes 11 are two in interval corresponding distribution;

two cores 2 are arranged, and the outer parts of the cores 2 are arranged in the square through holes 11 in a square fit mode.

Threaded holes 12 are formed in the template 1 on the side edge of the bottom of the through hole 11, three quarters of the threaded holes 12 are formed in the template 1, and one quarter of unformed parts of the threaded holes 12 correspond to the bottom of the mold core 2;

the screw 3 is screwed in the threaded hole 12, the bottom of the screw 3 is abutted to the bottom of the mold core 2 through the quarter unformed part of the threaded hole 12 to form a push-out structure, the screw 3 on the push-out structure is slowly screwed out of the threaded hole 12, the screw 3 can slowly eject the mold core 2 out of the mold core 2 from the through hole 11, the flash between the through hole 11 and the mold core 2 is cleaned, and the problem that the mold core 2 is completely knocked out of the through hole of the mold core 1 by using a hammer and a rubber rod and damaged is solved.

When the core 2 needs to be retracted, the screw 3 is screwed back in the threaded hole 12, and then the core 2 is pressed down into the through hole 11.

The outer side of the top of the screw 3 is hexagonal, so that the screw 3 can be screwed in and out in the threaded hole 12 conveniently by using the internal hexagonal cylinder. The template 1 at the end of the threaded hole 12 is provided with a counter bore section 121 for accommodating the hexagonal section outside the screw 3.

The hexagonal groove 31 is formed in the hexagonal section on the outer side of the accommodating screw 3, and an outer hexagonal wrench convenient to use is screwed.

The accommodating screw 3 positioned on the side of the hexagonal groove 31 is provided with a straight groove 32, so that the operation is convenient through a straight screwdriver.
