Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," "engaged," "hinged," and the like are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other suitable relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1, as an embodiment of the present invention, a production apparatus for a switch panel includes an upper mold 110 and a lower mold, and a receiving cavity 120 is disposed in the middle of the upper mold 110. The lower mold also includes a receiving cavity 120. The receiving cavity of the upper mold 110 and the receiving cavity of the lower mold form a switch panel cavity when the molds are closed. A plurality of mold cores 130 with cylindrical structures are arranged in the accommodating cavity 120. The cylindrical structure reduces the residence time of the switch panel cavity glue on the outer side wall of the mold core 130. When the mold is closed, the lower part of the mold core 130 abuts against the bottom of the accommodating cavity 120 of the lower mold. The middle part of each mold core 130 is provided with a glue injection hole 140, the middle part of the lower part of each mold core 130 is provided with a first drainage groove 150, and the orthographic projection of the first drainage groove 150 is a structure with straight lines at two sides and circular arcs at two ends. The lower part of each mold core 130 is also provided with two second drainage grooves 160, and the two second drainage grooves 160 are respectively positioned at two ends of the first drainage groove 150. Each second conduction groove 160 has a smaller cross-section at the end adjacent to the first conduction groove 150 and a larger cross-section at the end remote from the first conduction groove 150. When the mold core 130 abuts against the lower mold, the glue injection hole 140, the first drainage groove 150, the second drainage groove 160 and the accommodating cavity 120 are communicated. On the whole structure, the glue flows faster, and the production efficiency of the switch template is improved.
In a specific embodiment of the present invention, along the axial direction of the mold core 130, the depth of the middle portion of the first drainage groove 150 is greater than the depths of both ends, and the depth of the end of the second drainage groove 160 close to the first drainage groove 150 is greater than the depth of the end of the first drainage groove 150. The depth of the end of the second drainage groove 160 away from the first drainage groove 150 along the axial direction of the mold core 130 is 0.5-1 mm. So for behind injection moulding, the injecting glue hole is very thin with the connecting portion between injection moulding's flush mounting plate of switch, can make its separation when the drawing of patterns, like this, just need not special person to handle, just also need not carry out the condition that interior mouthful was cuted and then is leaded to influencing product quality. Moreover, the glue flowing speed is guaranteed.
In a specific embodiment of the present invention, the number of the mold cores 130 is three, the distance between the axes of every two adjacent mold cores 130 is the same, and the axes of the three mold cores 130 are located on the same plane. The junction of the glue injection hole 140 and the first drainage groove 150 and the junction of the first drainage groove 150 and the second drainage groove 160 are chamfered. Effectively reducing the residence time of the glue at the joint.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
