Greatly, production efficiency is low；Motor-driven Leave out thread, is driven by hydraulic system, is relatively rotated using plastic and Mold Ring with Screw Thread and is moved with opposite
Dynamic abjection screw thread, this core-pulling mechanism major defect are to need in addition to increase the relevant devices such as hydraulic system to make in die cost
It rises, and structure is complicated, manufacturing cost is high.
Utility model content
The utility model is intended to solve one of above-mentioned technical problem in the related technology at least to a certain extent.For this purpose,
The utility model proposes a kind of demolding structures effectively reduced cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of demolding structure, including mould bases and the mode being arranged in inside the mould bases, the mode include upper cores,
The type core for cooperatively forming the lower mode of type chamber with the upper cores and being arranged between the upper cores and lower mode, the type
The surface of core is provided with screw thread, and the mode is also embedded with for being inserted into the screw thread and playing rotation to the motion profile of type core
The bolt of guiding role, the type core are also rotatably connected to the take-up housing that the outside of mode is arranged in and the insertion take-up housing
In and drive the take-up housing along the inclined guide pillar moved far from mode direction, the inclined guide pillar is fixed in the mould bases.
As an improvement of the above technical solution, the mould bases includes being equipped with the top mold holder of upper cores and being equipped with lower die
The lower mold holder of benevolence, the inclined guide pillar are fixed in the top mold holder.
As a further improvement of the above technical scheme, be further fixed in the mould bases for limit take-up housing stroke and with
The screw that take-up housing abuts.
Further, the top mold holder is provided with boss, and the inclined guide pillar is fixed on the boss, the take-up housing setting
There is the groove for accommodating the boss, the take-up housing is abutted with the boss.
Further, wear-resistant block is provided between the boss and the take-up housing.
The beneficial effects of the utility model are: a kind of demolding structure, including mould bases and the mould being arranged in inside the mould bases
Benevolence, the mode include upper cores, with the upper cores cooperatively form type chamber lower mode and setting the upper cores and under
Type core between mode, the surface of the type core are provided with screw thread, and the mode is also embedded with for being inserted into the screw thread simultaneously
Play the bolt of rotary steering to the motion profile of type core, the type core is also rotatably connected to the cunning that the outside of mode is arranged in
In block and the insertion take-up housing and drive the take-up housing along the inclined guide pillar moved far from mode direction, the inclined guide pillar
It is fixed in the mould bases.It drives take-up housing to slide using inclined guide pillar, to produce mode with ejector half core, realizes demoulding, entirely
Process avoids reducing cost using additional hydraulic device.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the utility model mounting structure schematic diagram；
Fig. 2 is the mounting structure schematic diagram of bolt and type core in lower mode in the utility model.
Specific embodiment
Referring to figs. 1 to Fig. 2, a kind of demolding structure of the utility model including mould bases and is arranged in inside the mould bases
Mode, the mode include upper cores 2-1, the lower mode 2-2 for cooperatively forming type chamber with the upper cores 2-1 and setting in institute
The type core 3 between upper cores 2-1 and lower mode 2-2 is stated, the surface of the type core 3 is provided with screw thread 3-1, and the mode is also embedded
There are the bolt 2-21 for being inserted into the screw thread 3-1 and serving to the motion profile of type core 3 rotary steering, the type core 3
It is also rotatably connected in the take-up housing 4 that the outside of mode is set and the insertion take-up housing 4 and drives 4 edge of take-up housing
Far from the mobile inclined guide pillar 5 in mode direction, the inclined guide pillar 5 is fixed in the mould bases.
As an improvement of the above technical solution, the mould bases includes top mold holder 1-1 and the installation for being equipped with upper cores 2-1
There is the lower mold holder 1-2 of lower mode 2-2, the inclined guide pillar 5 is fixed on the top mold holder 1-1.
When demoulding to workpiece, top mold holder 1-1 is separated from each other with lower mold holder 1-2, while upper cores 2-1 and lower mode
2-2 is separated from each other, and the inclined guide pillar 5 being fixed in top mold holder 1-1 is mobile with top mold holder 1-1, drives take-up housing 4 sliding in mould bases
Dynamic, the bolt 2-21 being embedded in mode relative rotation and is slided in screw thread 3-1, makes to carry out under the pulling of 3 sliding seat 4 of type core
Rotation abjection.Whole process avoids reducing cost using additional hydraulic device.
Preferably, the type core 3 is rotatablely connected with take-up housing 4 by bearing.
As a further improvement of the above technical scheme, it is further fixed in the mould bases for limiting 4 stroke of take-up housing simultaneously
