Abstract
The utility model discloses a rubber roller injection mold, its characterized in that: the rubber roller forming die comprises a main die body, wherein a forming groove with a U-shaped cross section outline is arranged on the main die body, positioning inserts for sealing two ends of the forming groove are arranged at two ends of the forming groove, positioning holes for fixing a rubber roller core are arranged on the positioning inserts, and a forming cover with an arc-shaped cross section outline is arranged in the forming groove. The utility model discloses set up a curved shaping lid on the shaping groove of U-shaped to can extrude into convex with the higher authority of the liquid rubber in the shaping groove, thereby can reduce rubber material's quantity when moulding plastics, and reduce subsequent machining volume, not only guarantee the quality of moulding plastics, reduce manufacturing cost moreover.
Description
Technical field
The utility model relates to a kind of mold, especially a kind of rubber rollers injection mold.
Background technique
Rubber rollers are one of laser printer common components, and usually intermediate is that one layer of rubber is wrapped up outside iron core.Rubber
Glue is integrally formed using mold injection and iron core, and conventional method is using the closed injection molding of upper die and lower die, upper die and lower die
On be machined with forming tank, be altogether exactly a circular type chamber, the both ends of type chamber have mold insert to close and are used for secured core, should
The injection molding of kind of method main drawback is that: because entire type chamber is closed only gas vent exhaust, thus when the liquid of injection molding
When rubber injects, the intracavitary air of type is not easy to be discharged, and especially excludes to be difficult completely, have so as to cause the product being molded by scarce
It falls into.Another method is not need upper mold using open injection molding, and several U-type grooves, two end seal of U-type groove are only processed in lower die
It closes and interior secured core, the cross-sectional profiles for the roller being finally molded by is U-shaped, thus use machining will be U-shaped after being molded
Rubber processing at circle, this kind of method venting quality is good, but processing capacity is big and waste of material is big, thus high production cost.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of rubber rollers injection mold.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of rubber rollers injection mold, it is characterised in that: including main mould body, it is U which, which is equipped with cross-sectional profiles,
The forming tank of shape, the both ends of the forming tank are equipped with the positioning mold insert at closing forming tank both ends, and the positioning mold insert is equipped with and is used for
The location hole of fixed rubber rollers central spindle, the forming tank is interior to be equipped with the shaping cover that cross-sectional profiles are arc.
The cross-sectional profiles of the slot bottom of the forming tank are semicircle.
The shaping cover cross-sectional profiles are arc-shaped.
The distance on shaping cover two sides edge is less than the diameter of slot bottom cross section.
The shaping cover both ends are equipped with positioning cap.
It further include lid mounting plate, and the main mould body is equipped with multiple forming tanks, is fixed on the lid mounting plate several
Shaping cover corresponding with forming tank.
The lid mounting plate is equipped with positioning column.
Main mould body both ends are equipped with the end cap at closing forming tank both ends.
The beneficial effects of the utility model are: the utility model is provided with the molding of an arc in the forming tank of U-shaped
Lid, it is in the arc-shaped so as to squeeze the upper surface of the liquid rubber in forming tank, so that rubber material can be reduced in injection molding
The dosage of material, and subsequent machining amount is reduced, it not only ensure that injection molding quality, but also reduce production cost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the explosive view of the utility model；
Fig. 2 is the top view of main mould body.
Specific embodiment
Referring to Fig.1, Fig. 2, the utility model discloses a kind of rubber rollers injection molds, including rectangular main mould body 1, the master
Die body 1 is equipped with the forming tank 2 that cross-sectional profiles are U-shaped, and the cross-sectional profiles of the slot bottom of the forming tank 2 are semicircle, because
To need to be molded by circular roller, thus the slot bottom of the forming tank 2 of U-shaped will be circle, the both ends of the forming tank 2 be equipped with closing at
The positioning mold insert 3 at 2 both ends of type groove, in this example using rubber stopper, the positioning mold insert 3 is equipped with to be used positioning mold insert 3
In the shaping cover 4 in the location hole of fixed rubber rollers central spindle, the forming tank 2 equipped with cross-sectional profiles being arc, when forming tank 2
Shaping cover 4 is covered in forming tank 2 after the castable rubber of liquid needed for interior injection, and will be on castable rubber by shaping cover 4
The flat liquid level in face is squeezed into the arc to arch upward, preferably arc-shaped, thus 4 cross-sectional profiles of the shaping cover accordingly will be circular arc
The distance of shape, the 4 two sides edge of shaping cover is less than the diameter of slot bottom cross section, can be put into the forming tank of U-shaped in this way, and
And shaping cover 4 can be stuck in forming tank 2 convenient for extrusion forming, to reach saving rubber material, the subsequent machinery of reduction adds
The purpose of work amount.
4 both ends of shaping cover are equipped with positioning cap (not showing in figure), pass through the fixation of positioning cap and positioning mold insert 3
Shaping cover 4 is controlled in the depth of the forming tank 2 of U-shaped, and is molded with accurate.
As the further optimization of this structure, main mould body both ends are equipped with the detachable end at closing forming tank both ends
Lid, in this way before being put into rubber rollers central spindle and positioning mold insert can first encapsulating, gas can be more advantageous in this way from U-type groove mold
Interior discharge will not generate bubble using bigger hollow central spindle, to achieve the purpose that material-saving.It can hold when finally demoulding
Easily first end cap is removed, is then ticked from both ends by rubber rollers central spindle and positioning mold insert.
Further as this structure preferably further includes lid mounting plate 5, and the main mould body 1 be equipped with it is multiple at
Type groove 2, several shaping covers 4 corresponding with forming tank 2 are fixed on the lid mounting plate 5, and the lid mounting plate 5 is equipped with positioning
Column.By above structure, we can be realized batch and are molded, to greatly improve injection efficiency and reduce processing cost.
It above to a kind of rubber rollers injection mold provided by the utility model embodiment, is described in detail, herein
In apply specific case the principles of the present invention and embodiment be expounded, the explanation of above embodiments is only used
The method and its core concept of the utility model are understood in help；At the same time, for those skilled in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification is not
It is interpreted as limitations of the present invention.
