Description
Technical field
The utility model relates to a kind of mold, especially a kind of gear shaft press mounting die.
Background technique
In the product with gear structure, need to usually have gear shaft in plastic casing, to guarantee that gear shaft rotates
Fluency, be usually by interference fit, to prevent gear shaft from turning and for fixed gear shaft, between gear shaft and shell
It is dynamic, since using being interference fitted, so that manual assembly difficulty is big, precision is low.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of gear shaft press mounting die.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of gear shaft press mounting die, including bottom plate, lower template and cope plate, have between the lower template and cope plate
Die cavity corresponding with workpiece is provided with several guide posts on the bottom plate, offers in the lower template and matches with guide post sliding
The pilot hole of conjunction is provided with several buffer springs between the bottom plate and lower template, if offering in the die cavity of the lower template
Axis hole corresponding with gear shaft is done, is provided with pad post corresponding with axis hole on the bottom plate.
A heating plate is provided on the cope plate, the heating plate, which is embedded in, is provided with several heating wires.
Several heat-conductive thermo tubes are evenly arranged in the heating plate.
The pad post lower end is helicitic texture, and the pad post is mounted on bottom plate by being threadedly engaged, and can pass through rotation
The height of pad post adjusting pad post.
The beneficial effects of the utility model are: a kind of gear shaft press mounting die, including bottom plate, lower template and cope plate, institute
Stating has die cavity corresponding with workpiece between lower template and cope plate, be provided with several guide posts, the lower die on the bottom plate
The pilot hole being slidably matched with guide post is offered on plate, and several buffer springs, institute are provided between the bottom plate and lower template
It states and offers several axis holes corresponding with gear shaft in the die cavity of lower template, be provided with pad corresponding with axis hole on the bottom plate
Column, when work, gear shaft is put into axis hole, and padded by pad post, and product shell is packed into die cavity, is pushed by cope plate, with lower film
Product shell is fixed after template molding, when continuing to push cope plate, lower template overcomes buffer spring to continue to move down, so that
For gear shaft by the installation of gear shaft can be completed in the pad post indentation intracorporal gear shaft holes of shell, installation accuracy is high, and can realize certainly
Dynamic to be turned into industry, work efficiency is high.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side schematic view of the utility model.
Specific embodiment
Referring to Fig.1, Fig. 2, Fig. 1, Fig. 2 are the structural schematic diagrams of one specific embodiment of the utility model, as shown, one
Kind of gear shaft press mounting die, including bottom plate 1, lower template 2 and cope plate 3, have and work between the lower template 2 and cope plate 3
Part corresponding die cavity is provided with several guide posts 12 on the bottom plate 1, offers in the lower template 2 and guide post 12 is slided
The pilot hole of cooperation is provided with several buffer springs 4, opens in the die cavity of the lower template 2 between the bottom plate 1 and lower template 2
Equipped with several axis holes corresponding with gear shaft, it is provided with pad post 11 corresponding with axis hole on the bottom plate 1, when work, gear shaft
It is put into axis hole, and padded by pad post, product shell is packed into die cavity, pushes by cope plate, to product after molding with lower film template
Shell is fixed, and when continuing to push cope plate, lower template overcomes buffer spring to continue to move down, so that gear shaft is pressed by pad post
In the intracorporal gear shaft holes of shell, the installation of gear shaft can be completed, installation accuracy is high, and can realize automated job, work effect
Rate is high.
Preferably, a heating plate 5 is provided on the cope plate 3, the heating plate 5, which is embedded in, is provided with several fevers
Silk expands gear shaft holes, further facilitates the assembling of gear shaft to preheat to plastic casing.
Preferably, several heat-conductive thermo tubes are evenly arranged in the heating plate 5, so that the diffusion of even heat, avoids sending out
The case where raw heat build-up, damages plastic casing.
Preferably, 11 lower end of pad post is helicitic texture, and the pad post 11 is mounted on bottom plate 1 by being threadedly engaged,
And the height of pad post 11 can be adjusted by rotation pad post 11, to be suitable for the gear shaft of different fitting depths, the scope of application is wider.
Preferably, it is provided with heat discoloration paster in the heating plate 5, in order to which operator intuitively observes mold
Temperature avoids the excessively high damage plastic casing of temperature.
Preferably, bottom plate 1 is equipped with chill corresponding with pad post 11, and pad post 11 is made of steel, with reduce pad post 11 and
The temperature of gear shaft makes the easier loading of gear shaft using the principle expanded with heat and contract with cold.
The preferred embodiments of the present invention have been specifically described above, certainly, the utility model can also using with
The different form of above embodiment, those skilled in the art are made etc. on the premise of without prejudice to spirit of the invention
Same transformation or corresponding change, all should belong in the protection scope of the utility model.
