Abstract
The invention discloses a hollow brush handle of a toothbrush and a production method thereof, relating to the technical field of toothbrush production, in particular to the technical field of brush handle production. When the material is injected into the die cavity of the brush handle, any position of the brush handle is provided with a blow hole, gas is blown into the center of the brush handle, and the blow hole is sealed after the brush handle is shaped. In the hollow brush handle, the technical steps are reduced, a production period is shortened and manpower is saved because a chock plug does not need to be welded after the cavity is formed. Because gas is blown by positive pressure, the brush handle of any shape can be manufactured, the inner curve and the outer curve of the brush handle are similar, which is more favorable for saving brush handle material; compared with a solid brush handle, 10-50% of material can be saved; in addition, the brush handle has the advantages of high full degree, good finish degree, attractive appearance and better feel of an outer surface, and high density, and the intensity of the brush handle is higher than that of a common brush handle.
Description
Technical field
The present invention relates to the production technical field of toothbrush production technical field, particularly brush holder.
Background technology
Toothbrush handles in the past is a block handle, and punching is planted bristle, the toothbrush that formation can be brushed teeth then in the top.Because brush holder is macromolecular material, be difficult to degraded, in order to reduce pollution to environment, to reduce production costs, toothbrush manufacturing enterprise had produced a kind of brush holder and had been hollow toothbrush afterwards.Existing hollow handle is in order to form hollow inner chamber, need finish by the cooperation of inside and outside mould, internal mold withdraws from producing for convenience, can only the production hollow lumen not oversize, an end is big and the little hollow handle of the other end, after withdrawing from, internal mold can stay bigger through hole withdrawing from end (the normally rear end of brush holder), need during production again with chock plug of brush holder identical materials hot weld, therefore, the rear end fineness of the hollow handle made of method is not high thus, and, in order successfully to move back mould, need the long production cycle, directly influenced production efficiency.In addition, because the outer surface full weight of the brush holder that this technology forms is poor, shaping rate is low.
Summary of the invention
The object of the invention be to provide a kind of with short production cycle, brush holder outer surface full weight is good, be fit to a kind of hollow handle of the toothbrush of different shape brush holder.
The present invention includes brush holder, hollow lumen is set in the inside of described brush holder.
On described brush holder, be provided with the gas hole that the aperture is not more than 6mm.
The present invention also provide a kind of with short production cycle, brush holder outer surface full weight is good, be fit to a kind of production method of hollow handle of the toothbrush of different shape brush holder.
Technical solution of the present invention is:
To the mold cavity material feeding of brush holder the time, in any at least one position of brush holder gas hole is set, and is blown into gas to the brush holder center, treat the brush holder airtight gas hole in back that is shaped.
The present invention only need make the external mold of brush holder, all can be in the afterbody of brush holder and brush holder to any position at both sides between the neck and back by being blown into gas, and air pressure compressing macromolecular material is pushed to the external mold direction, therefore, the present invention need not to weld chock plug again after forming cavity, so reduced processing step, saved the production cycle and artificial.Owing to adopt malleation to be blown into gas, the present invention can make the brush holder of arbitrary shape, the interior external curve of brush holder is close, be more conducive to save the brush holder materials, but more solid brush holder material-saving 10～50%, and brush holder not only outer surface plumpness height, fineness is good, attractive in appearance, feel is better, and the intensity of its density height, brush holder also is higher than common brush holder.
For convenience of airtight gas hole, the aperture of described gas hole is not more than 6mm.The aperture of maximum gas hole is 6mm, is enough to be blown into gas, to form cavity.After forming cavity, both made this aperture of reservation also harmless, also can go out in gas bleeding, taking advantage of macromolecular material also and does not solidify fully and with the macromolecular material closure around the gas hole, formed the hollow lumen of body sealing, the vestige of the no gas hole in back that is shaped makes product brighter and cleaner.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is a kind of flow chart of the present invention.
Fig. 3 is an another kind of flow chart of the present invention.
The specific embodiment
Shown in 2, to the mold cavity material feeding of brush holder the time, the gas hole that in the rear end of brush holder a diameter to be set be 6mm, and be blown into gas to the brush holder center is treated the brush holder airtight gas hole in back that is shaped.
As shown in Figure 1, the brush holder 1 for forming is provided with hollow lumen 2 in the inside of brush holder 1.
Be provided with the gas hole 3 that the aperture is not more than 6mm in the rear end of brush holder 1.
When the present invention produces, also can from the front end 1/3rd of distance brush holder and apart from the brush holder rear end 1/3rd punishment a diameter is not set is 0 to 6mm gas hole 4,5, and be blown into gas to the brush holder center simultaneously, as shown in Figure 3.After waiting to finalize the design, can each gas hole 4,5 is airtight again, form complete cavity.
Claims (4)
1. a kind of hollow handle of toothbrush is characterized in that comprising brush holder, in the inside of described brush holder hollow lumen is set.
2. according to a kind of hollow handle of the described toothbrush of claim 1, it is characterized in that on described brush holder, being provided with the gas hole that the aperture is not more than 6mm.
3. production method of a kind of hollow handle of toothbrush according to claim 1, it is characterized in that the time to the mold cavity material feeding of brush holder, any at least one position at brush holder is provided with gas hole, and is blown into gas to the brush holder center, treats the airtight gas hole in brush holder shaping back.
4. according to the production method of a kind of hollow handle of the described toothbrush of claim 3, it is characterized in that the aperture of the described gas hole before airtight is 0～6mm.
