Description
Technical Field
The utility model belongs to the technical field of the mobile phone manufacturing technique and specifically relates to a point mould for cell-phone shell.
Background
At present, the mobile phone becomes one of the most extensive information transmission and interpersonal communication modes in the current society, and is a necessity in the life of people. The mobile phone comprises a mobile phone shell and a mobile phone screen, wherein the mobile phone shell comprises a front shell and a rear shell. In the manufacturing process of the mobile phone, after the electronic device is assembled inside the mobile phone shell, hot melt adhesive needs to be injected into the front shell of the mobile phone shell, and then the mobile phone screen is adhered to the front shell. The existing glue injection mode is manual glue injection which mainly depends on the operation proficiency of workers and is greatly influenced by human factors, so that the manual glue injection has uncertainty and great differentiation, the product quality is uneven, and the glue injection efficiency is low.
SUMMERY OF THE UTILITY MODEL
To the technical problem that traditional artifical injecting glue is influenced by the human factor greatly and product quality is uneven, the utility model provides a dispensing die utensil for cell-phone shell.
The utility model adopts the technical proposal that: a dispensing die utensil for cell-phone shell, including the base and with base articulated apron, but the apron is provided with the recess that is used for fixed cell-phone shell on the base through rotatory pressfitting on the base, the shape and the cell-phone shell of recess match, are provided with the logical groove that is used for some glue on the cell-phone shell on the apron. During injecting glue, in the recess on the base was installed with the cell-phone shell to operating personnel, then with the rotatory pressfitting of apron on the base, accomplish fixing of cell-phone shell, operating personnel reuses the injecting glue rifle and injects the round hot melt adhesive along the logical groove on the apron on the cell-phone shell, transports next process installation cell-phone screen with the cell-phone shell after the injecting glue is accomplished again. Operating personnel can be complete inject the glue that accords with the standard on the cell-phone shell under the help of logical groove, has guaranteed product quality, has improved injecting glue efficiency, even the completion injecting glue work that inexperienced novice operating personnel also can be quick. The size of the through groove is smaller than that of the groove because the through groove is used for helping an operator to inject glue on the mobile phone shell.
Further, a plurality of first pressure relief holes are formed in the groove and penetrate through the base. The recess is guaranteed to setting up in first pressure release hole and external air current is unblocked, installs the recess at the cell-phone shell after, and first pressure release hole can avoid forming the problem that the negative pressure leads to the cell-phone shell to be difficult for taking out between cell-phone shell and the recess.
Furthermore, a positioning pin is arranged on the base, and a positioning hole matched with the positioning pin is arranged on the cover plate. The installation accuracy between apron and the base has been guaranteed in setting up of locating pin and locating hole to just also guarantee the apron and go up the precision between logical groove and the recess in the cell-phone shell, just also guarantee the precision of injecting glue.
Furthermore, a plurality of second pressure relief holes are formed in the base and penetrate through the base. The second pressure relief hole ensures that the surface of the base is smooth to the outside air flow, and after the cover plate and the base are pressed together, the problem that the cover plate is not easy to open due to negative pressure formed between the cover plate and the base can be avoided.
Furthermore, a plurality of first magnetic devices are arranged on the base, and a second magnetic device matched with the first magnetic devices is arranged on the cover plate; the first magnetic means are arranged in-line on the base and the second magnetic means are arranged in-line on the cover. The first magnetic means and the second magnetic means may directly employ a permanent magnet of the prior art. First magnetic device and second magnetic device can guarantee that apron and the inseparable link together of base, improve the fixed effect to cell-phone shell in the base.
Furthermore, notches are formed in two sides of the base in the length direction and extend into the grooves. The setting of breach is convenient for operating personnel to take out the cell-phone shell from the recess. The method specifically comprises the following steps: the operating personnel stretch into the recess with thumb and forefinger through the breach in, upwards again can be light and easy take out the cell-phone shell.
Further, the edges of the through grooves are inclined planes. Because the apron has certain thickness, if do not set up the inclined plane on leading to the groove, still can be apart from cell-phone shell a bit distance when can lead to the injecting glue rifle to contradict on leading to the groove, there is slight error in the glue of follow-up injection cell-phone shell. The setting on inclined plane has been equivalent to the attenuate and has been led to groove edge cover plate thickness, makes the injecting glue rifle and cell-phone shell distance closer, reduces the error of injecting glue.
Furthermore, the cover plate is hinged with the base through the hinge, and the hinge has the advantages of simple structure, convenience in operation, low cost and the like.
Furthermore, the base is made of bakelite which has the advantages of high hardness, strong insulativity, static resistance, corrosion resistance, rust resistance, long service life, high temperature resistance and the like, and particularly, the cellphone case and the internal components thereof can be well protected due to the characteristics of strong insulativity and static resistance.
Furthermore, the cover plate is made of a PE plate, and compared with the base, the cover plate does not need high strength, so that the PE plate is selected to be made, still has the characteristics of strong insulation and static electricity prevention, and can well protect the mobile phone shell and internal components thereof.
The utility model has the advantages that:
1. the utility model discloses a dispensing die utensil can let the complete glue that accords with the standard of pouring into on the cell-phone shell of operating personnel, has guaranteed product quality, has improved injecting glue efficiency, even the completion injecting glue work that inexperienced new hand operating personnel also can be quick.
2. The utility model discloses a first magnetism device and second magnetism device can guarantee that apron and the inseparable linking together of base improve the fixed effect to cell-phone shell in the base.
3. The utility model discloses an inclined plane has been equivalent to the attenuate and has led to groove edge apron thickness, makes the injecting glue rifle more closely apart from the cell-phone shell, reduces the error of injecting glue.
