In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a keyboard key cap unloading tool of moulding plastics, its key lies in: including the connecting plate that is used for connecting the metal of key cap injection moulding machine discharge gate and makes, seted up a plurality of mounting grooves at the center of this connecting plate, every all installed the unloading passageway in the mounting groove, the lateral wall of this unloading passageway with the inside wall in close contact with of mounting groove, a ventilation hole has been seted up respectively to the left and right sides of unloading passageway the left and right sides of connecting plate is provided with first wind channel, and the air outlet in this first wind channel is linked together with the corresponding ventilation hole that is located the unloading passageway at both ends, is provided with the second wind channel on the connecting plate between two adjacent mounting grooves, the air outlet in second wind channel communicates the corresponding ventilation hole of the unloading passageway of its both sides.
Further, the cross-sectional area of the mounting groove is gradually reduced from top to bottom.
Furthermore, a supporting step is formed at the top of the mounting groove, and a supporting boss matched with the supporting step is formed at the top of the blanking channel.
Further, the upper surface of the supporting step is flush with the upper surface of the connecting plate.
Furthermore, a plurality of the mounting grooves are distributed on the connecting plate in an array manner.
Furthermore, four top corners of the connecting plate are respectively provided with a fixing hole, and the connecting plate is fixedly connected with the keycap injection molding machine through bolts penetrating through the fixing holes.
The utility model has the following remarkable effects:
the device has the advantages that the structure is simple, the realization is easy, the air flow generated by air blowing when the suction head on the manipulator unloads materials is fully utilized, and negative pressure is formed in the blanking channel, so that a downward acting force is formed on the keycap, the keycap can accurately fall into the blanking channel and enter the material storage box, and the phenomenon that the blanking channel is blocked due to displacement generated in the transfer process of the keycap is effectively avoided;
the feeding channel which is detachably arranged in the mounting groove can be replaced when one feeding channel is damaged, and the maintenance cost is greatly reduced.

FIG. 2 is a cross-sectional view of the present invention;
fig. 3 is a schematic structural view of the blanking channel in the present invention.
Detailed Description
The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.
As shown in fig. 1-3, a keyboard key cap injection molding blanking jig comprises a connecting plate 1 made of metal and used for being connected to a discharge port of a key cap injection molding machine, fixing holes 2 are respectively formed at four top corners of the connecting plate 1, the connecting plate 1 is fixedly connected with the key cap injection molding machine through bolts penetrating through the fixing holes 2, a plurality of mounting grooves (not shown) are formed in the center of the connecting plate 1, the mounting grooves are distributed on the connecting plate 1 in an array manner, a blanking channel 3 is arranged in each mounting groove, the outer side wall of the blanking channel 3 is in close contact with the inner side wall of the mounting groove to avoid air leakage, a vent hole 4 is respectively formed in each of the left side and the right side of the blanking channel 3, first air ducts 5 are arranged in the left side and the right side of the connecting plate 1, and air outlets of the first air ducts 5 are communicated with corresponding vent holes 4 of the blanking channels 3 at the two ends, and a second air duct 6 is arranged on the connecting plate 1 between two adjacent mounting grooves, and the air outlet of the second air duct 6 is communicated with the corresponding air holes 4 of the blanking channels 3 on two sides of the second air duct.
As shown in fig. 2, the cross-sectional area of mounting groove is from last to reducing gradually down, and is adapted, the cross-sectional area of unloading passageway 3 is from last to reducing gradually down, just the thickness of unloading passageway 3 is from last to consistent down to it reduces gradually from last to down in making the unloading passageway 3, and gravity that can make full use of the key cap makes it fall into in the storage case.
Referring to fig. 2 and 3, a supporting step is formed at the top of the mounting groove, a supporting boss 7 matched with the supporting step is formed at the top of the blanking channel 3, and the structure that the supporting step is matched with the supporting boss 7 is adopted, so that the blanking channel 3 can be conveniently clamped in the mounting groove on the premise of being convenient to replace.
