Abstract

A forming die mechanism comprises a die holder, a transverse sliding block and a guide block. The transverse sliding block comprises a sliding block body and a guide groove. The sliding block body is located in the open groove of the die holder in a sliding mode, and the guide groove is located in the sliding block body. The guide block is fixed in the open groove and located in the guide groove, and the guide groove can move relative to the guide block.

Description

Technical Field

[0001] This invention relates to a molding die mechanism, and more particularly to a molding die mechanism used in conjunction with a slider. Background Technology

[0002] Generally, when manufacturing molded products with slotted holes on their sides, a slider is required on the mold. Therefore, the molded product can only be ejected smoothly from the mold after the mold has cooled and the slider has retracted.

[0003] However, traditional sliders are insufficient in positioning and guiding functions on molding dies, and there is a risk that the sliders may get stuck in the molding die due to friction and expansion during the manufacturing process.

[0004] It is evident that the aforementioned technology still has inconveniences and shortcomings, and needs further improvement. Summary of the Invention

[0005] One object of the present invention is to provide a molding die mechanism to solve the difficulties mentioned in the prior art.

[0006] This invention provides a molding die mechanism. The molding die mechanism includes a die base, a transverse slider, and a guide block. The die base includes a seat body and a slot, with the slot located on the seat body. The transverse slider includes a slider body and a guide groove. The slider body is slidably located within the slot, and the guide groove is located on the slider body, having an outwardly flared inner wall. The guide block is fixed within the slot and located within the guide groove, and the guide groove is movable relative to the guide block. The guide block has an outwardly flared outer wall. When the slider body slides within the slot, it causes the guide groove to move relative to the guide block until the outwardly flared outer wall abuts against the outwardly flared inner wall, at which point the guide block prevents the transverse slider from sliding further.

[0007] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the guide groove further includes a guide inner wall. The guide inner wall is connected to the outer expanding inner wall and forms an obtuse angle with each other, with the major axis direction of the guide inner wall parallel to the transverse direction. The guide block further includes a guide outer wall. The guide outer wall is connected to the outer expanding outer wall and forms an obtuse angle with each other, with the major axis direction of the guide outer wall parallel to the transverse direction. When the guide groove moves relative to the guide block, the guide inner wall guides the guide outer wall to slide along the transverse direction.

[0008] According to one or more embodiments of the present invention, in the above-described molding die mechanism, there is a gap between the inner guide wall and the outer guide wall, the gap being between 15 and 20 micrometers.

[0009] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the slot has a receiving groove formed at the bottom of the slot, and the guide block is partially located within the receiving groove.

[0010] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the slot further includes a groove formed at the bottom of the receiving groove. A protruding insert is provided on the bottom surface of the guide block, and the insert removably extends into the groove to position the guide block within the receiving groove.

[0011] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the slider body has a pressing slope on the side opposite to the outwardly expanding inner wall. The transverse slider also includes a protective pad, which is fixedly attached to the pressing slope.

[0012] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the slider body has a flange on the side opposite to the pressing inclined surface.

[0013] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the guide block is funnel-shaped or V-shaped.

[0014] According to one or more embodiments of the present invention, in the above-described molding die mechanism, the transverse slider further includes an oblique guide hole and an oblique guide post. The oblique guide hole obliquely penetrates the slider body, and the oblique guide post is removably located within the oblique guide hole to move the transverse slider along the transverse direction.

[0015] Thus, through the above architecture, the molding die mechanism of the present invention can improve the defects of insufficient positioning function and lack of guiding function of the transverse slider on the molding die mechanism, and reduce the risk that the guide block will prevent the transverse slider from sliding in the guide groove due to thermal expansion, thereby improving the manufacturing process of the molding die mechanism.

[0071] Several embodiments of the present invention will be described below with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, these practical details are not essential in the various embodiments of the present invention. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner.

[0072] Figure 1 This is a side view of a molding die mechanism 10 according to an embodiment of the present invention. Figure 2 for Figure 1 An exploded view of the molding die mechanism 10. In this embodiment, as... Figure 1 and Figure 2As shown, the molding die mechanism 10 includes a male mold 100, a female mold 200 (or mold base), a transverse slider 300, and a guide block 400. The female mold 200 and the male mold 100 can be opened and closed detachably. The female mold 200 includes a base 210, a slot 220, and a cavity 250. The cavity 250 and the slot 220 are respectively formed on the base 210, and the cavity 250 is connected to the slot 220. More specifically, the cavity 250 is recessed in the top surface 211 of the base 210, and the slot 220 is recessed in the side of the base 210, and is respectively connected to the top surface 211 of the base 210 and one of its outer side walls 212.

[0073] The transverse slider 300 includes a slider body 310 and a guide groove 390. The slider body 310 is located within the slot 220, between the male mold 100 and the female mold 200. The slider body 310 is slidably located within the slot 220, meaning that the slider body 310 can slide back and forth along the Y-axis within the slot 220. Figure 1 The guide groove 390 is located on the slider body 310. The guide block 400 is fixed within the slot 220 and located within the guide groove 390. The guide groove 390 is movable relative to the guide block 400, meaning that the slider body 310 and the guide groove 390 can slide back and forth relative to the guide block 400 along the Y-axis. The major axis direction (e.g., the Y-axis) of the guide block 400 is orthogonal to the major axis direction (e.g., the X-axis) of the slider body 310.

[0074] Figure 3 for Figure 2 The horizontal slider 300 degrees is used to view a stereoscopic image from another perspective. More specifically, as... Figure 1 and Figure 2 As shown, the slider body 310 includes a top surface 311, a bottom surface 312, an inner side 313, an outer side 314, and two end surfaces 315. The two end surfaces 315 are arranged opposite each other, the inner side 313 and the outer side 314 are arranged opposite each other, and the top surface 311 and the bottom surface 312 are arranged opposite each other, located between the inner side 313 and the outer side 314 and between these end surfaces 315. A guide groove 390 is formed on the bottom surface 312 of the slider body 310, extends along the long axis (e.g., the Y-axis) of the guide block 400, and connects to the lower portion 316 of the slider body 310. Figure 3 The two opposite sides of the slider body 310. The bottom surface 312 of the slider body 310 contacts the bottom 221 of the slot 220. The outer side 314 of the slider body 310 has a pressing slope 320. The pressing slope 320 can be fixedly attached to at least one protective pad 370. However, the present invention is not limited thereto.

[0075] In this embodiment, the female mold 200 further includes a pair (i.e., two) of pressure blocks 360, which are disposed opposite to each other at the bottom 221 of the slot 220. Each pressure block 360 has an L-shaped cross-section, and a sliding channel 361 is defined between the pressure block 360 and the bottom 221 of the slot 220. The sliding channel 361 extends linearly along the Y-axis. The sliding channels 361 of these pressure blocks 360 face each other. The slider body 310 includes a pair (i.e., two) of sliding ribs 330. Figure 3 Each sliding rib 330 protrudes from one end surface 315 and extends linearly along the Y-axis. Therefore, the slider body 310 can be slidably embedded in the corresponding sliding channel 361 through these sliding ribs 330, and can slide back and forth along the Y-axis within the slot 220.

[0076] Furthermore, in this embodiment, such as Figure 2 As shown, the slot 220 also has a receiving groove 230. The receiving groove 230 is formed in the bottom 221 of the slot 220, and a portion of the guide block 400 is fixed within the receiving groove 230, while the other portion protrudes outside the receiving groove 230. For example, the screw hole 460 of the guide block 400 is locked into the receiving groove 230 by a bolt (not shown). However, the invention is not limited to the fixing method of the guide block 400. In other embodiments, the guide block 400 may even be integrally formed within the slot 220.

[0077] Furthermore, the slot 220 also includes a slot 240. The slot 240 is formed at the bottom 231 of the receiving groove 230, and the size of the slot 240 is smaller than the size of the slot 220. A protruding insert 450 is provided on the bottom surface 402 of the guide block 400. Thus, by removably inserting the insert 450 into the slot 240, the guide block 400 located in the receiving groove 230 can be more effectively positioned within the receiving groove 230. However, the invention is not limited thereto; in other embodiments, the aforementioned insert 450 and slot 240 may also be omitted.

[0078] Figure 4 for Figure 2 The top view of the guide block 400. In this embodiment, as... Figure 3 and Figure 4As shown, the guide groove 390 includes two opposing outer inner walls 391 and two opposing guide inner walls 392. The major axis direction (e.g., Y-axis) of each guide inner wall 392 is parallel to the major axis direction (e.g., Y-axis) of the guide block 400. One of the outer inner walls 391 and one of the guide inner walls 392 located on the same side of the guide groove 390 are connected to each other and are not coplanar, that is, the outer inner wall 391 and the guide inner wall 392 have an obtuse angle θ1 between them. Furthermore, in this embodiment, the guide inner wall 392 is a plane, and the outer inner wall 391 is an inclined plane relative to the guide inner wall 392. However, the present invention is not limited to the outer inner wall 391 necessarily being an inclined plane.

[0079] The guide block 400 includes two opposing outer walls 410 and two opposing guide walls 420. The major axis (e.g., the Y-axis) of each guide wall 420 is parallel to the major axis (e.g., the Y-axis) of the guide inner wall 392. One of the outer walls 410 and one of the guide walls 420 located on the same side of the guide block 400 are connected to each other and are not coplanar, that is, the outer walls 410 and 420 have an obtuse angle θ2 between them. Thus, when the guide groove 390 and the guide block 400 slide relative to each other, the guide wall 420 can guide the guide inner wall 392 to slide back and forth along the Y-axis.

[0080] Furthermore, in this embodiment, the guide block 400 also includes a first end face 430 and a second end face 440, with the first end face 430 being larger than the second end face 440. The outwardly flared outer walls 410 of the guide block 400 are respectively adjacent to the first end face 430, and the guide outer walls 420 of the guide block 400 are respectively adjacent to the second end face 440. Moreover, since the guide outer wall 420 is planar, the outwardly flared outer wall 410 is an inclined plane relative to the guide outer wall 420; however, the present invention is not limited to the outwardly flared outer wall 410 necessarily being an inclined plane.

[0081] Furthermore, to reduce the risk of jamming caused by frictional expansion of the transverse slider 300, the inner guide wall 392 of the guide groove 390 is provided with a clearance design, so that the inner guide wall 392 and the outer guide wall 420 are not tightly attached to each other, and there is still a slight gap G1 between them, for example, between 15 and 20 micrometers. However, the present invention is not limited to the above-mentioned dimensional changes.

[0082] Figures 5A to 5B They are respectively Figure 1 A schematic diagram illustrating the operation of the transverse slider 300 sliding on the female mold 200. (See diagram below.) Figure 2 and Figure 5AAs shown, the transverse slider 300 also includes a plurality of (e.g., 2) angled guide holes 340 and a plurality of (e.g., 2) angled guide posts 380. These angled guide holes 340 are parallel to each other, and each angled guide hole 340 obliquely penetrates the slider body 310 and connects the top surface 311 and the bottom surface 312 of the slider body 310.

[0083] Each angled guide hole 340 gradually approaches the outer side 314 from the top surface 311 to the bottom surface 312. More specifically, the axial direction 341 of each angled guide hole 340 deviates from the vertical direction (such as the Z-axis) and forms an acute angle θ3 with the vertical direction (such as the Z-axis). Figure 1 One end of the inclined guide post 380 is fixedly connected to the male mold 100, and the other end is detachably located inside the inclined guide hole 340. The major axis of the inclined guide post 380 is coaxial with the axial direction 341 of the inclined guide hole 340.

[0084] Thus, as Figure 5A and Figure 5B As shown, when the male mold 100 descends along the vertical direction (such as the Z-axis) and approaches the female mold 200 and the transverse slider 300 ( Figure 5B When the inclined guide post 380 presses vertically down into the inclined guide hole 340, the inclined guide post 380 pushes the slider body 310 laterally through the inclined guide hole 340, causing the slider body 310 to move laterally along the first lateral direction D1 (such as the Y-axis) within the slot 220, thereby completing the mold closing process. Figure 5B On the other hand, such as Figure 5A As shown, when the male mold 100 rises vertically away from the female mold 200 and the transverse slider 300, and the inclined guide post 380 pushes the inclined guide hole 340 vertically upward within the inclined guide hole 340, the inclined guide post 380 pushes the slider body 310 laterally through the inclined guide hole 340, so that the slider body 310 moves laterally within the slot 220 along the second transverse direction D2 (such as the Y axis) until the inclined guide post 380 completely disengages from the inclined guide hole 340, thus completing the mold opening process.

[0085] It should be understood that when the male mold 100 closes the female mold 200 and the transverse sliding block 300 to complete the mold closing process, the transverse sliding block 300, the cavity 250 of the male mold 100 and the female mold 200 together define a molding cavity C. Figure 1 This allows the molding cavity C to accept plastic and form a molded product (not shown in the figure).

[0086] Furthermore, when the male mold 100 closes onto the transverse slider 300, the male mold 100 is tightly pressed against the protective pad 370 of the slider body 310 to ensure the sealing quality of the molding cavity C. Moreover, since the protective pad 370 is a soft consumable material, it not only contributes to the sealing quality of the molding cavity C but also protects the transverse slider 300 and the male mold 100 from damage. The inner side 313 of the slider body 310 has a flange portion 350, which is used to create groove shapes on the side of the molded product after the male mold 100 is demolded. However, the present invention is not limited thereto.

[0087] Figures 6A to 6B They are respectively Figure 1 A schematic diagram illustrating the movement of the guide groove 390 of the transverse slider 300 relative to the guide block 400. (See diagram below.) Figure 6A and Figure 6B As shown, during the mold closing process, the slider body 310 slides within the slot 220 along the first transverse direction D1 (e.g., the Y-axis), thereby causing the guide groove 390 to move relative to the guide block 400 until the outer wall 410 of the guide groove 390 abuts against the inner wall 391 of the guide block 400. The guide block 400 thus prevents the transverse slider 300 from continuing to slide, thereby providing a guiding and positioning effect. When the guide groove 390 slides relative to the guide block 400 along the first transverse direction D1 (e.g., the Y-axis), the inner guide wall 392 of the guide groove 390 can guide the outer guide wall 420 of the guide block 400, allowing the guide groove 390 to slide more smoothly along the first transverse direction D1. At this time, the transverse slider 300 is abutted against by the outer expansion inner wall 391 of the guide block 400 and against the male mold 100 on the other hand, so that the transverse slider 300 is fixedly clamped between the guide block 400 and the male mold 100.

[0088] Conversely, during the mold opening process, the slider body 310 moves along the second transverse direction D2 (e.g., the Y-axis) within the slot 220, thereby causing the guide groove 390 to move relative to the guide block 400. At this time, the outer wall 410 of the guide groove 390 moves away from the inner wall 391 of the guide block 400, and the inner wall 392 of the guide groove 390 guides the outer wall 420 of the guide block 400, allowing the guide groove 390 to slide more smoothly along the second transverse direction D2 (e.g., the Y-axis).

[0089] Figure 7 This is a top view of a guide block 401 according to an embodiment of the present invention. Compared to the guide block 400 in the above embodiment, which is funnel-shaped... Figure 4 ),like Figure 7As shown, the guide block 401 in this embodiment is V-shaped. More specifically, the guide block 401 omits the aforementioned guide outer wall, such that the major axes of these extended outer walls 410 intersect each other. Each extended outer wall 410 directly connects to the first end face 430 and the second end face 440 of the guide block 401. Thus, since the directions in which the extended outer walls 410 extend toward the second end face 440 are close to each other, there is a significant gap G2 between the extended outer wall 410 and the guide inner wall 392. Therefore, the risk of the transverse slider 300 failing to slide within the guide groove 390 due to thermal expansion of the guide block 401 is further reduced (see reference). Figure 2 ).

[0090] Thus, through the above architecture, the molding die mechanism of the present invention can improve the defects of insufficient positioning function and lack of guiding function of the transverse slider on the molding die mechanism, and reduce the risk that the guide block will prevent the transverse slider from sliding in the guide groove due to thermal expansion, thereby improving the manufacturing process of the molding die mechanism.

[0091] Finally, the embodiments described above are not intended to limit the invention. Any modifications and refinements made by those skilled in the art without departing from the spirit and scope of the invention are protected under this invention. Therefore, the scope of protection of this invention shall be determined by the appended claims.
