However, in practice, the product may not adhere to the mold surface after being placed on the mold. If the mold surface does not adhere well to the product, it may cause damage between the mold and the product when the mold is closed. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a mold that enables the product to fit well with the mold surface without causing the mold to be crushed.

[0004] A mold for solving mold pressing according to an embodiment of the present invention includes a lower mold and a suction head. The lower mold is provided with a bearing surface for bearing a workpiece, and the bearing surface is provided with a receiving groove. The suction head is disposed in the receiving groove and has a connected adsorption end and a first connecting end. The adsorption end is used to adsorb the workpiece, and the first connecting end is used to communicate with a vacuum generator. The adsorption end extends to the outside of the receiving groove. The suction head is at least partially made of a flexible material that can be deformed. The suction head can deform under negative pressure so that the adsorption end is completely retracted into the receiving groove.

[0022] The following is for reference. Figures 1 to 4 A mold for solving the problem of mold pressing according to an embodiment of the present utility model will be described in detail.

[0023] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, a mold for solving mold pressing includes a lower mold 100 and a suction head 200. The lower mold 100 is provided with a bearing surface 100a for bearing a workpiece, and the bearing surface 100a is provided with a receiving groove 100b. The suction head 200 is disposed in the receiving groove 100b and has a connected adsorption end 210 and a first connecting end 220. The adsorption end 210 is used to adsorb the workpiece, and the first connecting end 220 is used to communicate with a vacuum generator. The adsorption end 210 extends to the outside of the receiving groove 100b. The suction head 200 is at least partially made of a flexible material that can be deformed. The suction head 200 can deform under negative pressure so that the adsorption end 210 is completely retracted into the receiving groove 100b.

[0024] In the mold of this application, the mold includes a lower mold 100 and a suction head 200. The upper surface of the lower mold 100 is provided with a bearing surface 100a for bearing the workpiece. A receiving groove 100b is machined on the bearing surface 100a. The suction head 200 is disposed in the receiving groove 100b. The suction head 200 is made of flexible material and has a connected adsorption end 210 and a first connecting end 220. The adsorption end 210 is used to adsorb the workpiece, and the first connecting end 220 is used to connect to a vacuum generator. In its natural state, the adsorption end 210 of the suction head 200 extends out of the receiving groove 100b. When the workpiece is placed on the bearing surface 100a, the adsorption end 210 abuts against the workpiece. When the vacuum generator is activated and generates negative pressure, the flexible suction head 200 undergoes elastic deformation under the negative pressure, causing the adsorption end 210 to completely retract into the receiving groove 100b. This allows the workpiece to be smoothly adsorbed by the suction head 200 and pulled onto the bearing surface 100a of the lower mold 100, thereby making the workpiece fit tightly against the mold surface. As can be seen from the above, by setting a suction head 200 on the lower mold 100 to adsorb the workpiece on the bearing surface 100a, the workpiece can be made to completely fit the bearing surface 100a of the lower mold 100, thereby effectively reducing the possibility of crushing between the workpiece and the mold due to poor fit during mold closing.

[0025] refer to Figure 2 and Figure 3In some embodiments of this utility model, the lower mold 100 is further provided with an installation channel, one end of which is connected to the receiving groove 100b; the mold also includes a pin 300, which is hollow and located in the installation channel. The pin 300 has a connected insertion end 310 and a second connection end 320. The insertion end 310 is plugged into and connected to the first connection end 220 and is connected to the first connection end 220. The second connection end 320 is used to communicate with the vacuum generator. Understandably, the lower mold 100 has an installation channel that connects to the receiving groove 100b. A centrally controlled insert pin 300 is installed in the installation channel. The insertion end 310 of the insert pin 300 is plugged into and connected to the first connection end 220 of the suction head 200 and remains connected. The second connection end 320 of the insert pin 300 is used to connect to the vacuum generator. The insert pin 300 serves as an intermediate connector between the vacuum generator and the suction head 200, facilitating the installation and replacement of the suction head 200. The hollow structure of the insert pin 300 ensures that the negative pressure is effectively transmitted to the suction head 200, ensuring the stability of the air path connection.

[0026] like Figure 3 As shown, in some embodiments, the peripheral surface of the insertion end 310 is provided with an anti-detachment protrusion 311. It can be understood that the annular anti-detachment protrusion 311 on the peripheral surface of the insertion end 310 of the insert pin 300 is used to increase the tightness of the connection between the insert pin 300 and the first connection end 220 of the suction head 200, reduce the possibility of accidental separation between the insert pin 300 and the suction head 200 under negative pressure or vibration, thereby further ensuring the stability of the air circuit connection.

[0027] like Figure 2 and Figure 3 As shown, in one embodiment, the anti-detachment protrusion 311 is provided with a guide surface 311a at one end near the bearing surface 100a. The guide surface 311a is used to guide the insertion end 310 into the first connecting end 220. The anti-detachment protrusion 311 is provided with a limiting surface 311b at one end away from the bearing surface 100a. The limiting surface 311b abuts against a part of the structure of the insertion end 310 and can prevent the insertion end 310 from being pulled out of the first connecting end 220. Understandably, the anti-detachment protrusion 311 has an inclined guide surface 311a at one end near the bearing surface 100a. The guide surface 311a facilitates the insertion of the plug end 310 into the suction head 200. The anti-detachment protrusion 311 has a vertical limiting surface 311b at one end away from the bearing surface 100a. The limiting surface 311b can abut against the suction head 200 structure to prevent the insert pin 300 from separating from the suction head 200. The guide surface 311a facilitates the installation operation between the suction head 200 and the insert pin 300, while the limiting surface 311b provides a mechanical locking function, further enhancing the reliability of the connection.

[0028] like Figure 2As shown, in one embodiment, multiple sets of anti-detachment protrusions 311 are spaced apart along the axial direction of the insertion end 310. It can be understood that the multiple sets of anti-detachment protrusions 311 spaced apart along the axial direction of the insertion end 310 form a multi-layer anti-detachment structure. The multiple sets of anti-detachment protrusions 311 disperse the force between the insert pin 300 and the suction head 200, so as to adapt to the use scenarios of higher negative pressure or frequent disassembly.

[0029] like Figures 1 to 4 As shown, in some embodiments, the lower mold 100 includes a mold core 110 and a mold base 120 that are detachably connected. The mold core 110 is provided with a first mounting hole 111, and the mold base 120 is provided with a second mounting hole 121. The first mounting hole 111 and the second mounting hole 121 together form a mounting channel. The insert pin 300 is provided with a shoulder structure 330. The end of the second mounting hole 121 near the mold core 110 forms a shoulder structure, and the shoulder structure 330 is disposed within the shoulder structure. It can be understood that the lower mold 100 is composed of a mold core 110 and a mold base 120 that are detachably connected by bolts. The mold core 110 is machined with a first mounting hole 111, and the mold base 120 is machined with a second mounting hole 121. The two are joined to form a mounting channel. The insert pin 300 is provided with a shoulder structure 330. The end of the second mounting hole 121 near the mold core 110 forms a shoulder structure, and the shoulder structure 330 is embedded within the shoulder structure for positioning. The split design of the lower mold 100 facilitates processing and assembly. The shoulder structure 330 and the hole shoulder structure work together to ensure accurate axial positioning of the insert pin 300 and prevent the insert pin 300 from being misaligned, which could lead to air leakage.

[0030] like Figure 2 As shown, in one embodiment, the end of the first mounting hole 111 near the mold base 120 is flared, with the cross-sectional area gradually increasing towards the mold base 120. It can be understood that the flared shape of the end of the first mounting hole 111 near the mold base 120 facilitates the insertion of the pin 300 into the first mounting hole 111 through the flared opening, reducing the assembly difficulty of the pin 300.

[0031] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the suction head 200 includes a deformable section 230, which is made of a flexible material capable of deformation. The two ends of the deformable section 230 are respectively connected to the adsorption end 210 and the first connecting end 220. It is understood that the adsorption end 210 and the first connecting end 220 are connected by the deformable section 230 made of flexible material. The deformable section 230 is designed to concentrate elastic deformation capabilities, ensuring that the adsorption end 210 can quickly retract into the receiving groove 100b.

[0032] refer to Figure 3In some embodiments of this utility model, the first connecting end 220 abuts against the bottom of the receiving groove 100b. It can be understood that the bottom of the receiving groove 100b abuts against the first connecting end 220 of the suction head 200 to limit the excessive displacement of the suction head 200 under negative pressure, avoid excessive compression or twisting of the suction head 200, and extend its service life.

[0033] refer to Figure 2 In some embodiments of this utility model, the distance between the adsorption surface of the adsorption end 210 and the bearing surface 100a is 0.1mm. It can be understood that setting the distance between the adsorption surface of the adsorption end 210 and the bearing surface 100a to 0.1mm ensures that the workpiece first contacts the adsorption end 210 and is adsorbed, and then, under negative pressure, the workpiece can be driven downwards by the suction head 200 and smoothly adhere to the bearing surface 100a, thus improving positioning accuracy.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
