Description
Technical Field
The utility model relates to an injection mold's technical field, in particular to fixed knot of hardware constructs in injection mold.
Background
In some injection molding products, it is sometimes necessary to provide hardware in the injection molding product, and generally, during injection, the hardware is placed in an injection mold and then injection molding is performed.
As shown in fig. 1-3, the conventional injection mold is generally configured to fix the hardware 200 by disposing the alignment pin 100 ' in the mold and disposing the alignment hole 200a on the hardware 200, aligning the alignment hole 200a with the alignment pin 100 ' and fitting the alignment pin 100 ' with the alignment hole 200 a. However, during the actual injection molding process, hardware 200 is susceptible to movement under the injection pressure in the manner shown by the arrows in FIG. 1.
The existing solution is to increase the diameter of the positioning pin, so that the positioning pin is in interference fit with the positioning hole of the hardware, and the hardware is fastened on the positioning pin. However, the diameter of the positioning pin is not well controlled, and if the positioning pin and the positioning hole are matched too tightly, the hardware is not easy to install, and if the positioning pin and the positioning hole are not matched tightly, the hardware still floats.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model aims at providing a fixed knot of hardware constructs in injection mold to solve the hardware and be difficult to effectively fix the problem in injection mold.
In order to achieve the above object, the utility model provides a fixed knot of hardware constructs in injection mold has a plurality of locating holes on this hardware, this fixed knot construct include with the locating hole one-to-one sets up the pilot pin in injection mold, and each the pilot pin all is the prism form, the hardware passes through the interference fit of locating hole and pilot pin and fixes in injection mold.
Optionally, the positioning hole is circular, and when the positioning hole is in interference fit with the positioning needle, the inner wall of the positioning hole abuts against the lateral edge of the positioning needle.
Optionally, the positioning pin includes a circular truncated cone and a positioning column, which are coaxially disposed, and the positioning column is prism-shaped.
Optionally, the positioning column is in a triangular prism shape.
Optionally, the top edge and corner of the positioning column are rounded.
Optionally, the top edge angle of the positioning column is chamfered.
The technical scheme of the utility model through setting up the pilot pin into the prism to reduce the interference area of contact of pilot pin and hardware, make the locating hole of hardware and the face interference between the pilot pin become the multiple spot interference, can guarantee the elasticity between hardware and the pilot pin from this, avoid the hardware to remove at the in-process of moulding plastics, the installation of the hardware of also being convenient for simultaneously.

Detailed Description
The utility model provides a fixed knot of hardware constructs in injection mold.
Referring to fig. 4-5, fig. 4 is a schematic structural diagram of the fixing pin provided by the present invention, and fig. 5 is a schematic diagram of a hardware and a positioning pin provided by the present invention.
As shown in fig. 4-5, in the embodiment of the present invention, the hardware 200 has a plurality of positioning holes 200a, the fixing structure includes positioning pins corresponding to the positioning holes 200a one-to-one and disposed in the injection mold, each positioning pin is prism-shaped, and the hardware 200 is fixed in the injection mold by interference fit of the positioning holes 200a and the positioning pins.
Optionally, in this embodiment, the positioning hole 200a of the hardware 200 is provided as a circular hole, and when the positioning hole 200a is in interference fit with the positioning pin, an inner wall of the positioning hole 200a abuts against a lateral edge of the positioning pin.
Optionally, in this embodiment, the positioning pin includes a circular truncated cone 110 and a positioning column 120, which are coaxially disposed, and the positioning column 120 is prism-shaped. When the positioning hole 200a of the hardware 200 is installed, the positioning hole is sleeved in the corresponding positioning column 120 and is in interference fit with the positioning column 120, so that the hardware 200 is fixed on the positioning column 120. The bottom surface of the metal fitting 200 abuts on the circular table 110, thereby maintaining a constant interval from the cavity wall of the injection mold.
Optionally, in this embodiment, the positioning column 120 is set to be triangular prism-shaped, so that the hardware 200 is fixed through interference fit of three points, the structure is simple, the manufacturing is convenient, the tightness between the hardware 200 and the positioning pin can be ensured, and the installation of the hardware 200 is also convenient.
The technical scheme of the utility model through setting up the pilot pin into the prism form to reduce the interference area of contact of pilot pin and hardware 200, make the locating hole 200a of hardware 200 and the face interference between the pilot pin become the multiple spot interference, can guarantee the elasticity between hardware 200 and the pilot pin from this, avoid hardware 200 to remove at the in-process of moulding plastics, the installation of the hardware 200 of also being convenient for simultaneously.
Optionally, as shown in fig. 4, in the present embodiment, an edge 120a between the top surface and the side edge of the positioning pillar 120 is rounded or beveled. Because the outside diameter of reference column 120 is greater than the aperture of hardware 200's locating hole 200a, can reduce the bore of the upper end of reference column 120 through carrying out radius angle or chamfer angle to the top edges and corners 120a of reference column 120 to in hardware 200's locating hole 200a emboliaed the reference column, make things convenient for hardware 200's installation.
The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
