However, there is a gap between the iron part and the iron part limiting posts, and the iron part can move within a certain range, resulting in large dimensional differences at the iron part after molding and making it unusable subsequently. Summary of the Utility Model
[0003] In view of the above problems, the present application provides an iron part pressing device for a handle mold and a handle mold, which are used to solve the technical problem that there is a gap between the iron part and the iron part limiting posts, and the iron part can move within a certain range, resulting in large dimensional differences at the iron part after molding and making it unusable subsequently.
[0004] To achieve the above object, in a first aspect, the inventor provides an iron part pressing device for a handle mold, including:
[0005] A pressing block, which is vertically penetrated with a through hole. The lower end of the pressing block is a slope surface for contacting the iron part.
[0006] An elastic component, one end of which is connected to the pressing block, and the other end of which is used to be connected to the fixed template of the handle mold.
[0007] A fastener, one end of which passes through the through hole and is used to be connected to the fixed template of the handle mold.
[0008] Wherein, the elastic component is used to make the pressing block move in the vertical direction, and the pressing block applies a force to the iron part to press the iron part against the iron part limiting post.
[0009] Different from the prior art, the technical solution of the present application is provided with a pressing device specifically acting on the iron part. The force generated by the elastic deformation of the elastic component is applied to the pressing block, so that the pressing block moves downward in the vertical direction. The slope surface of the pressing block pushes the iron part against the iron part limiting post, preventing the iron part from moving, making the size of the iron part after molding stable and controllable, and ensuring normal subsequent use.
[0010] As an implementation manner of the present utility model, the pressing block includes a connecting portion and a force-applying portion. The connecting portion is vertically penetrated with a through hole. The top surface of the connecting portion is connected to one end of the elastic component, and the bottom surface of the connecting portion is connected to the force-applying portion. The force-applying portion has a slope surface.
[0011] In this way, the connecting portion is used to connect the elastic component and the fastener, and the force-applying portion is used to act on the iron part, saving materials and having a simple structure.
[0012] As an embodiment of the present utility model, the pressing block is integrally formed.
[0013] In this way, the pressing block is integrally formed, and its structure is more firm and stable.
[0014] As an embodiment of the present utility model, the elastic component includes more than two springs. One end of the spring is connected to the top surface of the connecting portion, and the other end of the spring is used to connect to the fixed template of the handle mold.
[0015] In this way, the elastic component has elasticity, can elastically contract when subjected to pressure, and can restore its initial shape when the pressure disappears. The elastic component can be made of metal elastic materials such as metal springs, or can be made of non-metal elastic materials such as rubber and silica gel. By providing more than two springs, the iron piece can be better forced, so that the iron piece can be closely attached to the iron piece limiting post.
[0016] As an embodiment of the present utility model, the elastic component includes four springs. The top surface of the connecting portion is rectangular, and one spring is provided at each of the four corners of the rectangle.
[0017] In this way, four springs are provided according to the shape of the top of the connecting portion. The four springs are dispersedly arranged so that the pressing block is more evenly stressed, and thus the iron piece is also evenly stressed.
[0018] As an embodiment of the present utility model, the fastener is a bolt, a screw or a stud.
[0019] In this way, the fastener can be an existing bolt, screw or stud. Its top is used for threaded connection with the fixed template of the handle mold, which is convenient for adjusting the position of the fastener, so that the elastic component deforms or returns to its original state.
[0020] As an embodiment of the present utility model, the cross-section of the through hole is stepped, the fastener is an internal hexagonal stepped bolt, and the smaller diameter end of the internal hexagonal stepped bolt is used to connect to the fixed template of the handle mold.
[0021] In this way, by setting the fastener as an internal hexagonal stepped bolt, compared with an ordinary bolt, its fastening effect is better after installation and it is not easy to loosen. And the special structure of the step can make the bolt evenly distribute the fastening force, reduce stress concentration and improve the stability of the connection.
[0022] To achieve the above object, in a second aspect, the inventor provides a handle mold, including:
[0023] The fixed mold plate comprises a fixed mold core, an iron piece, an iron piece limiting column, and a device for pressing the iron piece of the handle mold as provided by the inventors above, wherein the iron piece is installed on the fixed mold core through the iron piece limiting column, and there is a gap between the iron piece and the iron piece limiting column, and the side of the iron piece away from the fixed mold core is provided with the iron piece pressing the iron piece of the handle mold;
[0024] The movable mold plate is arranged below the fixed mold plate, and the movable mold plate includes a movable mold core.
[0025] Different from the prior art, the technical solution of the present application uses an iron piece clamping device to clamp the iron piece against the iron piece limiting column, thereby avoiding the movement of the iron piece, thereby making the size of the formed iron piece more stable.
[0026] As an implementation mode of the utility model, a side of the iron piece away from the fixed mold core has a curved surface, which is used to make the iron piece pressing device of the handle mold contact with the curved surface.
[0027] In this way, the iron piece clamping device contacts the arc surface of the iron piece, and the arc surface plays a role of arc transition, and can be more easily clamped to the iron piece limit column when subjected to force.

[0051] According to some embodiments of the present application, please refer to Figure 1 The present embodiment relates to a handle mold 100, comprising a fixed mold plate 1 and a movable mold plate 2, the fixed mold plate 1 comprising a fixed mold core 11, an iron piece 12, an iron piece limiting column 13 and an iron piece clamping device 14 for the handle mold 100, the iron piece 12 is installed on the fixed mold core 11 through the iron piece limiting column 13, there is a gap between the iron piece 12 and the iron piece limiting column 13, and the iron piece clamping device 14 for the handle mold 100 is arranged on the side of the iron piece 12 away from the fixed mold core 11; the movable mold plate 2 is arranged below the fixed mold plate 1, and the movable mold plate 2 comprises a movable mold core 21.
[0052] The technical solution of the present application uses the iron piece clamping device 14 to clamp the iron piece 12 against the iron piece limiting column 13, thereby preventing the iron piece 12 from moving, thereby making the size of the formed iron piece 12 more stable.
[0053] According to some embodiments of the present application, optionally, Figure 2 As shown, the side of the iron piece 12 away from the fixed mold core 11 has a curved surface 121 for making the iron piece pressing device 14 of the handle mold 100 contact the curved surface 121 .
[0054] In this way, the iron piece pressing device 14 contacts the arc surface 121 of the iron piece 12 , and the arc surface 121 plays the role of arc transition, and can be pressed against the iron piece limiting column 13 more easily when subjected to force.
[0055] According to some embodiments of the present application, please refer to Figures 3 to 9, this embodiment also relates to an iron part tightening device 14 for the handle mold 100, which includes a tightening block 141, an elastic component 142, and a fastener 143. The tightening block 141 is provided with a through hole 1414 along the vertical direction Y. The lower end of the tightening block 141 is an inclined surface 1411 for contacting the iron part 12; one end of the elastic component 142 is connected to the tightening block 141, and the other end of the elastic component 142 is used to connect to the fixed template 1 of the handle mold 100; one end of the fastener 143 passes through the through hole 1414 and is used to connect to the fixed template 1 of the handle mold 100; wherein, the elastic component 142 is used to move the tightening block 141 along the vertical direction Y, and the tightening block 141 applies a force to the iron part 12 to tighten the iron part 12 against the iron part limiting post 13.
[0056] Among them, one end of the fastener 143 (i.e., the upper end of the top of the fastener 143, and the bottom of the fastener 143 is used to limit the sliding of the tightening block 141) is used to be threadedly connected to the fixed template 1 of the handle mold 100, and the tightening block 141 is slidably connected to the fastener 143 through the through hole 1414. Therefore, during actual use, first tighten the fastener 143, and the entire tightening block 141 moves upward along the vertical direction Y, so that the elastic component 142 is compressed and deformed. At this time, there is a gap between the iron part 12 and the iron part limiting post 13, and the gap between the tightening area 122 of the iron part 12 and the fixed mold core 11 is also large. Then, loosen the fastener 143, and the tightening block 141 moves downward along the fastener 143 under the action of the elastic component 142, and the inclined surface 1411 moves accordingly and acts on the iron part 12, and the iron part 12 moves into the fixed mold core 11 until it abuts against the side wall of the iron part limiting post 13. At this time, there is no gap between one side of the iron part 12 and the iron part limiting post 13, and the gap between the tightening area 122 of the iron part 12 and the fixed mold core 11 becomes smaller.
[0057] The technical solution of this application is provided with a special tightening device for the iron part 12. The force of the elastic deformation of the elastic component 142 is applied to the tightening block 141, so that the tightening block 141 moves downward along the vertical direction Y. The inclined surface 1411 of the tightening block 141 pushes the iron part 12 against the iron part limiting post 13, preventing the iron part 12 from moving, making the size of the formed iron part 12 stable and controllable, and ensuring normal subsequent use.
[0058] According to some embodiments of this application, optionally, as Figure 7 shown, the tightening block 141 includes a connecting portion 1412 and a force applying portion 1413. The connecting portion 1412 is provided with a through hole 1414 along the vertical direction Y. The top surface of the connecting portion 1412 is connected to one end of the elastic component 142, the bottom surface of the connecting portion 1412 is connected to the force applying portion 1413, and the force applying portion 1413 has an inclined surface 1411.
[0059] In this way, the connecting part 1412 is used to connect the elastic component 142 and the fastener 143, and the force - applying part 1413 is used to act on the iron part 12, saving materials and having a simple structure.
[0060] According to some embodiments of the present application, optionally, the pressing block 141 is integrally formed.
[0061] In this way, the pressing block 141 is integrally formed, and its structure is more firm and stable.
[0062] According to some embodiments of the present application, optionally, as Figure 3 and Figure 6 shown, the elastic component 142 includes more than two springs. One end of the spring is connected to the top surface of the connecting part 1412, and the other end of the spring is used to connect to the fixed template 1 of the handle mold 100.
[0063] In this way, the elastic component 142 has elasticity, can elastically contract when under pressure, and can restore its initial shape when the pressure disappears. The elastic component 142 can be made of metal elastic materials such as metal springs, or can also be made of non - metal elastic materials such as rubber and silica gel. By providing more than two springs, the force can be better applied to the iron part 12, so that the iron part 12 can be closely attached to the iron part limiting post 13.
[0064] According to some embodiments of the present application, optionally, as Figure 3 and Figure 6 shown, the elastic component 142 includes four springs. The top surface of the connecting part 1412 is rectangular, and one spring is provided at each of the four corners of the rectangle.
[0065] A through - hole 1414 is formed in the middle of the connecting part 1412, so that the subsequent springs can be evenly stressed when deforming and contracting.
[0066] In this way, four springs are provided according to the shape of the top of the connecting part 1412. The four springs are dispersedly arranged, so that the pressing block 141 is more evenly stressed, and thus the iron part 12 is also evenly stressed.
[0067] According to some embodiments of the present application, optionally, the fastener 143 is a bolt, a screw or a stud.
[0068] In this way, the fastener 143 can be an existing bolt, screw or stud. Its top is used for threaded connection with the fixed template 1 of the handle mold 100, which is convenient for adjusting the position of the fastener 143, so that the elastic component 142 deforms or returns to its original state.
[0069] According to some embodiments of the present application, optionally, as Figure 6 shown, the cross - section of the through - hole 1414 is stepped, and the fastener 143 is an internal - hexagon stepped bolt. The smaller - diameter end of the internal - hexagon stepped bolt is used to connect to the fixed template 1 of the handle mold 100.
[0070] Thus, by setting the fastener 143 as an internal hexagonal stepped bolt, compared with ordinary bolts, its fastening effect after installation is better and it is not easy to loosen. Moreover, the special structure of the step can make the bolts evenly distribute the fastening force, reduce stress concentration and improve the stability of the connection.
