Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention is a mold for producing a silica gel earphone post-hanging, which includes a squirt nozzle 1, a panel 2, a cold water plate 3, an upper plate 5, a lower plate 6, an ejector plate 7, and a bottom plate 8; specifically, the squirt nozzle 1 is fixed on the panel 2 through four countersunk holes 9, in addition, a cold water plate 3 is also required to be installed below the panel 2, a cold water inlet device 10 is arranged on the side surface of the cold water plate 3, and after the pipeline is connected, circulating water can enter the interior of the cold water plate 3 from the cold water inlet device 10 and then is discharged, so that the cold water plate keeps relatively low temperature, and liquid silica gel is radiated; meanwhile, the cold water plate 3 is also provided with a cold runner which is communicated with the squirt nozzle 1, an upper template 5 is additionally arranged below the cold water plate 3, a silica gel runner is arranged on the upper template 5 and is communicated with the cold runner, and a lower template 6 is arranged below the upper template 5; more importantly, as shown in fig. 2, an upper mold core 11 and a lower mold core 12 are arranged between the upper mold plate 5 and the lower mold plate 6, and as shown in fig. 3, a mold core 16 is further installed between the upper mold core 11 and the lower mold core 12, the mold core 16 is communicated with the silica gel flow passage, and the mold core 16 can fix a framework of a silica gel hanger in the cavities of the upper mold core 11 and the lower mold core 12; an ejector pin plate 7 is required to be arranged below the lower template 6, an ejector pin body 18 is arranged on the ejector pin plate 7, and the ejector pin body 18 penetrates through the lower template 6 and the lower mold core 12 to be abutted against the mold core 16, so that the mold core is conveniently ejected out of the lower mold core 12; finally, the ejector plate 7 is mounted on the base plate 8.

In this embodiment, through add upper and lower mould benevolence between upper and lower mould for the skeleton of hanging behind the earphone can be fixed between upper and lower mould benevolence, vulcanizes the shaping in the outside of skeleton under the effect of upper and lower mould benevolence by liquid silica gel, for the fashioned mould of solid-state silica gel, can make the hardness on product surface lower, with this obtains better comfort.

Still referring to fig. 1 and 2, in another embodiment of the present invention, in order to avoid the over-mature and blockage of the silica gel in the cold runner before the forming, a first heat insulation plate 4 may be additionally arranged between the cold water plate 3 and the upper mold plate 5; based on a unified idea, two square irons 20 can be arranged on the upper part of the bottom plate 8, and the ejector plate 7 is arranged between the two square irons 20; a second heat insulation plate 21 is arranged between the two square irons 20 and the lower template 6.

Further, in order to ensure the structural integrity of the mold, the upper mold core 11 can be installed in a groove at the lower part of the upper mold plate 5, the lower mold core 12 can be installed in a groove at the upper part of the lower mold plate 6, and a circular hole groove is further formed at the lower part of the upper mold core 11 and is respectively communicated with the silica gel flow channel and the mold core 16. On the other hand, in order to make the outside of the thimble body 18 on the thimble plate 7 sleeved with the belleville spring 19, as shown in the figure, the thimble plate 7 is provided with four thimble bodies 18, and each thimble body 18 is sleeved with one belleville spring 19; more importantly, in order to obtain the key part with the shape of the hanging lug during production, the two sides of the lower template 6 are respectively provided with a line 14, the line 14 is in power connection with a slide block 15, and the slide blocks 15 are also arranged on the two sides of the lower template 6; then, oblique inserting bodies 13 are arranged at the upper parts of the row positions 14, and the oblique inserting bodies 13 are used for connecting the upper template 5 and the lower template 6.

Referring to fig. 1 to 3, in practical use, according to the above preferred embodiment of the present invention, before forming, the auxiliary titanium wire is first inserted into the framework of the silica gel ear, and then the material is inserted into the mold core, and finally placed inside the lower mold plate for fixing. When the mold works, silica gel is poured from the squirt nozzle 1, meanwhile, clear water is injected into the two sides of the cold water plate 2, and the cold water plate is cooled through the cold runner in the cold water plate 3. At this moment, because the operating temperature of machine is higher and higher, in order to avoid silica gel to block up at the cold runner is ripe before the shaping excessively, install heat insulating board 4 of cope match-plate pattern 5 and played fine isolation effect, half-grown silica gel finally can flow in the round hole recess of the last mould benevolence 11 of cope match-plate pattern 5, in the lower mould benevolence 12 of lower mould board 6, we can put the skeleton of product material in advance, through cope match-plate pattern 5, the cooperation processing of lower mould board 6, the slider 15 of side can promote the slide 14 and extrude inwards, relative force about producing, hang the button portion of appearance behind this obtaining the earphone. The formed silica gel earphone is hung behind and can be firmly fixed at the top of a mouth sleeve of the mold core 16, the ejector plate 7 is driven to move upwards by the elasticity of the disc spring 19, an ejector pin on the ejector plate 7 ejects the mold core 16 out of a cavity of the lower mold core 12, and finally the silica gel earphone is taken out and hung behind. And hanging the silica gel earphone taken out, and pulling out the auxiliary titanium wire by using tweezers to leave a through hole for threading once.

This mould need wear supplementary titanium silk postvulcanization shaping on the material, follow-up pulls out supplementary titanium silk and can leave a through-hole in product inside, makes things convenient for the follow-up threading of customer.
