Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In the related art, the data line outer mold 140 is a shell for protecting the data line plug 170, and the data line plug is generally flat, i.e. the width of the plug is larger than the thickness, and a part of the data line with a safety standard size has a definite requirement for the thickness of the data line outer mold 140, for example, the society such as USB-IF (USB Implementers Forum, USB developer forum)/MFI (apple certification) requires that the maximum thickness of the data line outer mold 140 is not more than 6.5mm/6.25mm, which makes the injection molding precision requirement of the data line outer mold 140 in the thickness direction higher than the injection molding precision requirement in the width direction.
As shown in fig. 1-2, the data line is usually formed by injection molding with a single-sided feeding, and the pressure during injection molding acts on one side of the data line plug 170, so that the data line plug 170 is easy to move in the mold cavity due to uneven stress, and the phenomenon of glue shortage after injection molding of the data line outer mold 140 is serious, and the defect is difficult to overcome even through machine adjustment during production and manufacture.
As shown in fig. 3-5, a common solution to this drawback is to change the mold of the outer mold molding into simultaneous feeding with two sides, and the simultaneous feeding with two sides can solve the problem that the pressure of two sides of the data line plug 170 is unbalanced to a certain extent during the injection molding, but for some data line products, such as the data line products with the length of the data line plug 170 being greater than 30mm or the thickness being less than 0.8mm, the situation that the data line plug 170 is rocked in the mold cavity to cause the glue shortage after the injection molding of the data line outer mold 140 is easy to occur, for this situation, a thimble is usually added in the mold, and the thimble needs to be used to press against the data line plug 170 during the injection molding, so that a thimble hole exists on the surface of the data line outer mold 140 after the injection molding, which damages the integrity of the appearance and reduces the waterproof performance of the data line plug 170. In addition, for the products using the ultra-soft wire or the wire in the empty pipe state, the mold using the simultaneous feeding of both sides cannot avoid the phenomenon of glue shortage caused by the wrinkling of the wire in the forming process of the outer mold 140 of the data line.
As shown in fig. 6-10, a first aspect of the embodiments of the present application provides an injection mold 100, the injection mold 100 for injection molding a data line outer mold 140. The injection mold 100 is provided with a cavity (not shown in the figure) inside, the cavity is used for accommodating the data line plug 170, the outer surface of the injection mold 100 is provided with an injection port 110, and the top wall of the cavity and the bottom wall of the cavity are respectively provided with a first feed port 120 and a second feed port 130. The first feed port 120 may include a single opening or may include a plurality of openings; the second feed port 130 may include a single opening or may include a plurality of openings. The injection port 110 may be connected to the first and second feed ports 120 and 130 via pipes or via connecting channels formed in the injection mold 100. The number of injection ports 110 may be one, and one injection port 110 is simultaneously connected to the first feed port 120 and the second feed port 130. The number of injection molding openings 110 may be two, and the two injection molding openings 110 are correspondingly communicated with the first feeding opening 120 and the second feeding opening 130 respectively. The number of injection molding openings 110 can be more, and the plurality of injection molding openings 110 correspondingly communicate with the first feed opening 120 and/or the second feed opening 130.
When the data line plug 170 is injection molded, injection molding raw materials are injected into the injection molding opening 110, the injection molding raw materials are injected into the cavity after passing through the first feed opening 120, firstly contact with the bottom wall of the cavity, the top wall of the cavity, the bottom wall of the data line plug 170 and the top wall of the data line plug 170, then flow between the side wall of the cavity and the side wall of the data line plug 170, the whole cavity is filled, the injection molding raw materials partially cover the data line plug 170 to form the data line outer mold 140, and the data line outer mold 140 can be demoulded after the injection molding raw materials are cooled and molded. The injection molding material is thermoplastic plastic material, such as PC (Polycarbonate), and different injection molding materials need different injection temperatures and injection pressures, and the specific injection temperatures and injection pressures can be determined according to the selected injection molding materials.
The injection mold 100 of the embodiment of the application can avoid the situation that the data line plug 170 shakes in the mold cavity to cause the glue shortage after injection molding as much as possible, can ensure the injection molding effect of the upper surface and the lower surface without adding the ejector pins in the mold, and also can solve the situation that the shaking of the product in the mold cavity causes the glue shortage after molding when the three-plate mold is molded in a design mode. In addition, for the products using the super flexible wires or wires in the empty pipe state, the pressure of feeding the wires at the same time is equal up and down when the outer data wire mold 140 is formed, so that the stress bending of the wires is avoided, and the phenomenon of glue shortage caused by wrinkling in the forming process of the outer data wire mold 140 is reduced.
In summary, since the first feeding hole 120 and the second feeding hole 130 are respectively disposed on the top wall and the bottom wall of the cavity, the injection molding materials can be simultaneously fed from the upper direction and the lower direction, and the feeding pressures are the same, the data line plug 170 basically does not displace up and down, the injection molding materials can preferentially cover the upper surface and the lower surface of the data line plug 170, and the situation of glue shortage on the upper surface and the lower surface of the data line plug 170 is avoided. With respect to the side surface of the data line plug 170, since the data line overmold 140 is relatively loosely limited in the width direction, the data line overmold 140 may have a thicker injection layer in the width direction, and even if the data line plug 170 is offset in the width direction, a lack of adhesive is less likely to occur. Meanwhile, the appearance integrity of the outer mold 140 of the data line can be improved, the production yield of the data line is improved, and the production cost is reduced.
In some embodiments, the injection mold 100 may include a first mold and a second mold, which may be attached together or separated to facilitate the access of the data line plug 170. The first mould orientation the surface of second mould is provided with first injection groove, the second mould orientation the surface of first mould is provided with the second injection groove, first injection groove with the second injection groove surrounds the formation the die cavity, the diapire of first injection groove and the diapire of second injection groove is provided with respectively first feed inlet 120 and second feed inlet 130. In order to facilitate alignment of the first mold with the second mold, the first mold and the second mold may be provided with a positioning hole and a positioning pin, respectively. Of course, the injection mold 100 may be further formed by combining a plurality of sub-molds, and only a cavity is formed by enclosing the plurality of sub-molds. The injection port 110 may be disposed on the first mold, the second mold, or both the first mold and the second mold. It should be noted that the cavity is not only formed by the enclosing of the first injection molding groove and the second injection molding groove, but also the cavity is arranged in the first mold, and the second mold only plays a role of sealing the cavity. Or the cavity is arranged on the second die, and the first die only plays a role of sealing the cavity.
As shown in fig. 9, in some embodiments, the first feed port 120 is disposed at an edge of a bottom wall of the first injection molding groove (not shown), and the second feed port 130 is disposed at an edge of a bottom wall of the second injection molding groove (not shown). In general, the junction between the outer mold 140 and other components is easily damaged, and injection molding is performed from the edge, so that the junction between the outer mold 140 and other components has a good injection molding effect. For example, the connection position of the data line plug 170 and the transmission line 180 is easy to be damaged, at this time, the first feeding port 120 may be disposed at the junction of the data line plug 170 and the transmission line 180, so as to ensure the injection molding quality of the junction of the data line plug 170 and the transmission line 180, and improve the service life of the data line.
As shown in fig. 10, in some embodiments, the first feed port 120 provided in the first injection groove coincides with the second feed port 130 provided in the second injection groove, and the projection positions on the die-bonding surface coincide. If the front and back surfaces of the data line plug 170 have the same structure, the injection molding quality of the front and back surfaces of the data line plug 170 can be ensured to be consistent as much as possible, and the consistency of the injection molding quality is improved. If the front and back structures of the data line plug 170 are different, the positions of the first feed port 120 and the second feed port 130 may be adjusted according to the actual situation, so that the projection positions of the first feed port 120 disposed in the first injection molding groove and the projection positions of the second feed port 130 disposed in the second injection molding groove on the die-bonding surface do not coincide.
As shown in fig. 11-13, in some embodiments, the side wall of the cavity is provided with a third feeding port 150, and specifically, the third feeding port 150 may be disposed on the side wall of the first injection molding groove, may be disposed on the side wall of the second injection molding groove, may also be disposed on the side wall of the first injection molding groove and the side wall of the second injection molding groove at the same time, that is, a part of the third feeding port 150 is disposed on the side wall of the first injection molding groove, and another part is disposed on the side wall of the second injection molding groove. The injection port 110 is in communication with the third feed port 150, and the third feed port 150 may include a single opening or may include a plurality of openings. In some cases, the thickness required for injection molding may be different on the left and right sides of the data line plug 170, and it may be difficult to ensure that the injection molding material injected from the first and second feed ports 120 and 130 fills the entire cavity, or even if the cavity can be filled, a large injection molding pressure is required. For this purpose, a third feed opening 150 may be provided on the side of the data line plug 170 where injection molding is desired to be thicker, to ensure the injection molding quality of that side.
As shown in fig. 11 and 13, in some embodiments, the side wall of the cavity is further provided with a fourth feeding port 160, and specifically, the fourth feeding port 160 may be disposed on the side wall of the first injection molding groove, may be disposed on the side wall of the second injection molding groove, may be disposed on the side wall of the first injection molding groove and the side wall of the second injection molding groove at the same time, that is, a part of the fourth feeding port 160 is disposed on the side wall of the first injection molding groove, and another part is disposed on the side wall of the second injection molding groove. The injection molding port 110 is in communication with the fourth feed port 160, the fourth feed port 160 is disposed opposite to the third feed port 150, and the fourth feed port 160 may include a single opening or may include a plurality of openings. The first feed port 120, the second feed port 130, the third feed port 150 and the fourth feed port 160 are all communicated with the injection molding port 110, and the pressures of the first feed port 120, the second feed port 130, the third feed port 150 and the fourth feed port 160 are the same, so that the pressures received by the upper surface, the lower surface and the two side surfaces of the data line plug 170 are the same, the forces in all directions can be mutually offset, the data line outer mold 140 basically cannot shift during injection molding, the injection molding success rate of the data line outer mold 140 is improved, and the injection molding speed is improved. For some objects with smaller rigidity and easy deformation, the injection molding success rate is also better, and the possibility of glue shortage caused by deformation due to uneven stress is reduced in the injection molding process.
As shown in fig. 14, a second aspect of the embodiments of the present application provides a method for manufacturing a data line external mold 140, where the method for manufacturing the data line external mold 140 includes the following steps: placing the data line plug 170 into the cavity of the injection mold 100; injection molding raw materials are injected from an injection port 110 arranged on the outer surface of the injection mold 100, so that the injection molding raw materials are simultaneously injected into the cavity through a first feed port 120 arranged on the top wall of the cavity and a second feed port 130 arranged on the bottom wall of the cavity, the data line plug 170 is subjected to injection molding, and a data line outer mold 140 is formed on the periphery of the data line plug 170.
In summary, since the injection molding material is injected into the cavity through the first feeding port 120 disposed on the top wall of the cavity and the second feeding port 130 disposed on the bottom wall of the cavity, the injection molding material can preferentially cover the upper surface and the lower surface of the data line plug 170, so as to avoid the situation of adhesive shortage on the upper surface and the lower surface of the data line plug 170.
In some embodiments, injection molding material is injected from a first feed port 120 disposed in a top wall of the cavity and a second feed port 130 disposed in a bottom wall of the cavity at the same pressure. The same pressure of the injection molding raw materials can ensure that the upper surface and the lower surface of the data line plug 170 are stressed identically, and displacement of the data line plug 170 caused by the injection molding pressure is avoided.
In some embodiments, after the step of placing the data line plug 170 within the cavity of the injection mold 100, further comprises: injection molding material is injected from an injection port 110 provided on the outer surface of the injection mold 100, so that the injection molding material is simultaneously injected into the cavity through a first feed port 120 provided on the top wall of the cavity, a second feed port 130 provided on the bottom wall of the cavity, and a third feed port 150 provided on the side wall of the cavity. The third feed port 150 may be used to inject the injection molding material simultaneously with the first feed port 120 and the second feed port 130, or may be used to inject the injection molding material after the first feed port 120 and the second feed port 130 inject the injection molding material for a period of time.
