DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-8 An injection mold for a front ventilated decorative panel of an automobile provided by an embodiment of the present invention comprises an injection molding machine 1, on which a front cavity module 2 and a rear cavity module 3 are installed, and a mold opening and closing telescopic oil cylinder for providing a driving force for the reciprocating movement of the rear cavity module 3 is fixed on the injection molding machine 1, and the output shaft of the mold opening and closing telescopic oil cylinder is fixed to the rear cavity module 3, and the mold opening and closing telescopic oil cylinder can make the front cavity module 2 and the rear cavity module 3 in a mold closing state in an extended state, and the mold closing telescopic oil cylinder can make the front cavity module 2 and the rear cavity module 3 in a separated state in a retracted state, and the front cavity module 2 and the rear cavity module 3 in a mold closing state can form a mold cavity structure 4, and the mold cavity structure 4 is connected to the extrusion end of the injection molding machine 1 through a conducting mechanism 5, and the conducting mechanism 5 comprises:

[0033] The flow channel structure 6 includes a first groove body 6.1 provided on the front cavity module 2, the first groove body 6.1 is connected to the mold cavity on the front cavity module 2, and a second groove body 6.2 is provided on the rear cavity module 3 to align with the first groove body 6.1, and the second groove body 6.2 is connected to the mold cavity on the rear cavity module 3. When the first groove body 6.1 and the second groove body 6.2 are in a mold closing state, the flow channel structure 6 is formed between the first groove body 6.1 and the second groove body 6.2, and the plastic fluid in the injection molding machine 1 can be introduced into the mold cavity structure 4;

[0034] The cutting structure 7 comprises a plug-in cavity 7.1 provided on the second groove body 6.2, the length direction line of the plug-in cavity 7.1 is parallel to the moving direction line of the rear cavity module 3, a long strip plate 7.2 is inserted in the plug-in cavity 7.1, and the long strip plate 7.2 has a blocking effect on the cavity opening of the plug-in cavity 7.1, and a flow port 7.3 aligned with the flow channel structure 6 is provided on one end of the long strip plate 7.2 extending into the flow channel structure 6, and the inner contour surface of the flow port 7.3 is flush with the inner contour surface of the flow channel structure 6, and a cutting unit 7.4 is provided on the flow port 7.3, and the cutting unit 7.4 can cut off the material handle in the flow channel structure 6 during the separation process of the front cavity module 2 and the rear cavity module 3;

[0035] In actual use, the extrusion end of the injection molding machine 1 introduces the molten plastic into the mold cavity structure 4 through the runner structure 6. After cooling and solidification, the plastic located in the mold cavity structure 4 is the target product, that is, the automobile front ventilating trim panel, and the plastic located in the runner structure 6 is the material handle. At this time, the rear cavity module 3 moves away from the front cavity module 2 under the contraction and pulling of the mold opening and closing telescopic cylinder. At the same time, the material handle runs through the flow port 7.3, which is conducive to the automobile front ventilating trim panel and the material handle moving along with the rear cavity module 3. The two components move synchronously, thereby completely separating the front ventilated panel and the material handle from the front cavity module 2. As the rear cavity module 3 continues to move, the long strip 7.2 retracts toward the inside of the plug-in cavity 7.1. During this retracting movement, the cutting unit 7.4 moves along with the long strip 7.2, thereby cutting off the plastic material handle in the flow channel structure 6. As a result, the material handle of the automobile front ventilated panel is removed during the demolding process, eliminating the need for manual shearing and cutting, thereby improving the production efficiency of the injection molding of the automobile front ventilated panel.

[0036] In another embodiment provided by the present invention, a plurality of guide rail holes 3.1 are provided on the block of the rear cavity module 3, and a guide column 3.2 fixed to the injection molding machine 1 is slidably penetrated in each guide rail hole 3.1, and the guide rail column 3.2 is transmission-connected to the long strip plate 7.2 through a transmission assembly 8, and the axis of the guide column 3.2 is parallel to the moving trajectory of the rear cavity module 3, and the rear cavity module 3 moves along the axis of the guide column 3.2 through the guide rail hole 3.1;

[0037] The transmission assembly 8 includes a connection port 8.1 connecting the guide rail hole 3.1 with the plug-in cavity 7.1, a gear unit 8.2 is rotatably installed in the connection port 8.1, a first rack unit 8.3 meshing with the gear unit 8.2 is provided on the long plate 7.2, a short rack unit 8.4 located on the moving stroke of the rear cavity module 3 is fixed on the column body of the guide column 3.2, and when the gear unit 8.2 and the short rack unit 8.4 are meshed and transmitted, the long plate 7.2 undergoes corresponding telescopic movement in the plug-in cavity 7.1;

[0038] Furthermore, the short rack unit 8.4 includes a track groove 8.41 formed on the body of the guide column 3.2, the length direction line of the track groove 8.41 is parallel to the axis line of the guide column 3.2, and a tooth block 8.42 capable of meshing and transmitting with the gear unit 8.2 is fixed at the bottom of the track groove 8.41;

[0039] In actual use, when the formed front enclosure ventilation trim and the material handle are completely separated from the front cavity module 2, the rear cavity module 3 reaches the position of the tooth block 8.42 on the track groove 8.41. As the rear cavity module 3 continues to move, the gear unit 8.2 passes through the tooth block 8.42, and the gear unit 8.2 is meshed with the tooth block 8.42, so that the gear unit 8.2 rotates forward, and the gear unit 8.2 rotates forward and meshes with the first rack unit 8.3 on the long plate 7.2, so that the long plate 7.2 moves toward the inside of the plug-in cavity 7.1.

[0040] In another embodiment provided by the present invention, a cooling water channel 2.1 is provided in the front cavity module 2, a receiving groove 2.2 aligned with the plug-in cavity 7.1 is provided on the first trough body 6.1, an elastic tube 2.3 for maintaining normal conduction of the cooling water channel 2.1 is fixed in the receiving groove 2.2, when the flow port 7.3 is aligned with the flow channel structure 6, the end of the long strip 7.2 is adapted to be inserted into the receiving groove 2.2, and the elastic tube 2.3 is squeezed by the long strip 7.2 in a flattened state, and the elastic tube 2.3 can exert a force on the long strip 7.2 to move toward the plug-in cavity 7.1 when guiding the flow;

[0041] In actual use, when the extrusion end of the injection molding machine 1 introduces the molten plastic into the mold cavity structure 4 through the runner structure 6, the mold cavity structure 4 needs to be cooled and dissipated. At this time, the coolant is poured into the cooling water channel 2.1 opened in the front cavity module 2 to flow, thereby accelerating the cooling and heat dissipation of the mold cavity structure 4. When the coolant in the cooling water channel 2.1 passes through the elastic tube 2.3 in the receiving groove 2.2, the elastic tube 2.3 expands in the receiving groove 2.2, thereby applying a force to the long strip 7.2 to move toward the plug-in cavity 7.1, causing the long strip 7.2 to move toward the plug-in cavity 7.1. In this process, the flow port 7.3 forms a pre-cut on the side of the material handle that has not yet been cooled and finalized in the runner structure 6, which is beneficial to reducing the diameter of the cut surface of the material handle.

[0042] In another embodiment provided by the present invention, the cutting unit 7.4 includes a sliding groove 7.41 provided on the long strip plate 7.2. Specifically, the notch of the sliding groove 7.41 is located on the inner wall surface of the flow port 7.3. A cutting blade 7.42 is provided in the sliding groove 7.41. One end of the cutting blade 7.42 is hinged to the sliding groove 7.41. The other end of the cutting blade 7.42 is connected to the sliding groove 7.41 via a spring 7.43. At this time, the blade surface of the cutting blade 7.42 forms a blocking surface on the notch of the sliding groove 7.41.

[0043] In actual use, when the long strip 7.2 moves inward toward the inside of the plug-in cavity 7.1, the cutting blade 7.42 is squeezed with the solidified material handle, so that the cutting blade 7.42 deflects toward the inside of the sliding groove 7.41 around the hinged end until the cutting blade 7.42 contacts the inner wall of the sliding groove 7.41. At this time, the spring 7.43 is in a compressed deformation state, and the blade of the cutting blade 7.42 is in an oblique state with the solidified material handle. As the long strip 7.2 continues to move inward, the blade of the cutting blade 7.42 in an oblique state cuts off the material handle, and the cut material handle falls off from the rear cavity module 3.

[0044] In another embodiment provided by the present invention, the first rack unit 8.3 includes a slide rail groove 8.31 provided on the long strip plate 7.2, a first rack 8.32 is slidably engaged with the slide rail groove 8.31, the first rack 8.32 can slide along the slide rail groove 8.31, the bottom of the slide rail groove 8.31 is connected to the top of the slide groove 7.41 through a through hole 8.33, one end of the cutting blade 7.42 is hinged to the slide groove 7.41 through a pin structure 13, the pin structure 13 includes a column 13.1 fixedly passed through the cutting blade 7.42, the bottom end of the column 13.1 is rotatably installed with the inner wall of the slide groove 7.41, the top end of the column 13.1 is movably passed through the through hole 8.33, the top surface of the column 13.1 is parallel to the top surface of the long strip plate 7.2, and the top of the column 13.1 is provided with a slot 13.2 that can be engaged with the first rack 8.32;

[0045] In actual use, when the front cavity module 2 and the rear cavity module 3 are in the mold closing state, the first rack 8.32 is clamped in the clamping groove 13.2, thereby limiting the deflection of the cutting blade 7.42 in the sliding groove 7.41, and maintaining the stability of the cutting edge surface of the cutting blade 7.42 on the notch of the sliding groove 7.41. When the gear unit 8.2 rotates forward, the first rack 8.32 is driven by the meshing of the gear unit 8.2, thereby sliding away from the clamping groove 13.2 in the slide groove 8.31 until the first rack 8.32 is completely disengaged from the clamping groove 13.2. At this time, the first rack 8.32 contacts the end of the slide groove 8.31, and the gear unit 8.2 continues to rotate forward, thereby causing the long strip 7.2 to retract.

[0046] In another embodiment provided by the present invention, a column hole 9 parallel to the insertion cavity 7.1 is opened on the cavity of the rear cavity module 3, and a push rod 10 is adapted to be movably inserted in the column hole 9, and the push rod 10 can separate the product from the rear cavity module 3 during the separation process of the front cavity module 2 and the rear cavity module 3;

[0047] The gear unit 8.2 includes a wheel shaft 8.21 rotatably mounted vertically in the rear cavity module 3, a first gear 8.22 capable of meshing with the gear block 8.42 is fixedly mounted on the wheel shaft 8.21, and a first annular gear structure 8.23 ​​meshing with the first rack unit 8.3 is provided on the wheel shaft 8.21;

[0048] Furthermore, the bottom end of the wheel shaft 8.21 is located in the column hole 9, and the rod body of the ejector rod 10 is provided with a second annular gear structure 8.24, and the rod body of the ejector rod 10 is provided with a second rack structure 11 meshing with the second annular gear structure 8.24;

[0049] During actual use, when the gear unit 8.2 rotates forward, the long strip 7.2 is retracted and the ejector rod 10 is extended from the column hole 9, thereby pushing the product formed on the rear cavity module 3, so that the product is detached from the rear cavity module 3. Similarly, when the rear cavity module 3 moves in the reverse direction, the gear unit 8.2 meshes with the tooth block 8.42 during the process of passing through the tooth block 8.42, so that the gear unit 8.2 rotates in the reverse direction, thereby the long strip 7.2 is extended and the ejector rod 10 is retracted from the column hole 9, thereby keeping the surface of the cavity structure 4 and the runner structure 6 in a flat state again.

[0050] In another embodiment provided by the present invention, a conical hole 12 connected to the extrusion end of the injection molding machine 1 is provided on the first trough body 6.1, and the axis line of the conical hole 12 is parallel to the moving trajectory line of the rear cavity module 3, so that when the rear cavity module 3 is away from the front cavity module 2, the material handle in the conical hole 12 can be separated from the front cavity module 2.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
