Description

Technical Field

[0001] This utility model relates to the field of mold forming and manufacturing technology, and in particular to a molding die for automotive parts. Background Technology

[0002] Many automotive components require mold forming during manufacturing. For example, the high-voltage electrical distribution box, a key automotive part, has multiple connector holes for mounting plugs. Therefore, during the molding process, a core-pulling mechanism corresponding to these connector holes needs to be installed on the molding die. Existing high-voltage electrical distribution box molding dies typically include an upper mold base, upper mold plate, upper mold core, lower mold core, lower mold plate, and lower mold base. A cavity and a core are respectively located in the upper and lower mold cores. A slider core-pulling mechanism is installed between the upper and lower mold plates. This mechanism includes a slider and a core rod connected to it. When the upper mold plate moves upward, causing the slider to move, the slider moves in conjunction with the core rod to pull the core out of the mold core. While this structure achieves core pulling, it requires the slider core-pulling mechanism to work in conjunction with the upper mold plate, resulting in a complex overall structure, requiring more space, and a larger overall mold size. Furthermore, the more interconnected the mechanisms, the more prone to malfunctions, leading to excessive maintenance and potentially affecting the overall lifespan of the mold.

[0003] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0043] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0044] A molding die for an automotive part includes an upper mold assembly and a lower mold assembly connected to each other.

The lower mold assembly includes a lower template 30 and a lower mold base 40, the lower template 30 being embedded in the upper surface of the lower mold base 40. The lower surface of the upper template 20 has a recessed upper cavity 21, and the upper surface of the lower template 30 has a recessed lower cavity 31. The upper cavity 21 and the lower cavity 31 are adapted to form a cavity for manufacturing an automotive part. A core protrusion 32 is provided inside the lower cavity 31. The upper mold base 10 is provided with... The gating gate 11 and the runner 12 connected to the gating gate 11 are provided. The outlet 121 of the runner 12 is connected to the cavity. An auxiliary flow block 70 is provided on the right slider 63. The upper end of the auxiliary flow block 70 extends into the runner 12. An arc-shaped auxiliary inflow groove 71 is provided on the side of the upper end of the auxiliary flow block 70 facing the cavity. The two ends of the auxiliary inflow groove 71 are connected to the runner 12 and the outlet 121 of the runner 12, respectively. Here, the auxiliary flow block 70 can play the role of assisting the inflow, and the arc-shaped auxiliary inflow groove 71 can play the role of buffering the inflow to slow down the inflow speed.

[0045] In this embodiment, a left-side core-pulling mechanism 50 and a right-side core-pulling mechanism 60, which can move laterally, are provided between the upper mold base 10 and the lower mold base 40. The left-side core-pulling mechanism 50 includes a left-side cylinder 51, a left-side linkage rod 52, a left-side slider 53, and a left-side core block 54 connected in sequence.

The right-side core-pulling mechanism 60 includes a right-side cylinder 61, a right-side linkage rod 62, a right-side slider 63, and a right-side core block 64 connected in sequence. The right-side core block 64 can move towards or away from the right side of the core protrusion 32. In this way, after the upper mold base 10 and the lower mold base 40 are separated, the left-side core block 54 can be moved by the left-side cylinder 51, and the right-side core block 64 can be moved by the right-side cylinder 61 to achieve left and right-side core pulling respectively. This realizes the cylinder core-pulling structure design, reduces the space occupation, and the cylinder core-pulling structure does not need to cooperate with the upper mold movement. The structural design is simple and ingenious, reduces later maintenance, and ensures the service life of the mold.

[0046] In this embodiment, the left cylinder 51 is fixedly connected to the left side of the lower mold base 40 via the left mounting seat 80, and the right cylinder 61 is fixedly connected to the right side of the lower mold base 40 via the right mounting seat 90. Six left core pillars 55 are connected to the right end of the left core block 54, and the six left core pillars 55 are arranged at intervals along the front-back direction to form six holes on the left side of the product. Two right core pillars 65 are connected to the rear left end of the right core block 64, and the two right core pillars 65 are arranged at intervals along the front-back direction to form two holes on the right side of the product.

[0047] In this embodiment, a support plate assembly is provided at the bottom of the lower mold base 40. The support plate assembly includes two vertical plates 101 and two horizontal plates 102. The two vertical plates 101 are symmetrically arranged with a vertical front-to-back spacing. The two horizontal plates 102 are respectively fixedly connected to the lower ends of the two vertical plates 101, and the upper ends of the two vertical plates 101 are respectively fixedly connected to the front and rear ends of the bottom of the lower mold base 40. A buffer space 103 is formed between the lower mold base 40, the two vertical plates 101, and the two horizontal plates 102. Two stacked buffer plates are arranged within the buffer space 103. The two buffer plates are an upper buffer plate 104 and a lower buffer plate 105, which are fastened together by positioning screws. The bottom front and rear ends of the lower buffer plate 105 abut against the upper ends of the two horizontal plates 102, respectively. A shock-absorbing component, such as a shock-absorbing spring, can be installed between the upper buffer plate 104 and the lower mold base 40. Thus, the design of the support plate assembly with the buffer space 103 and the buffer plates improves its shock absorption capacity, strengthens the overall structural strength, enables it to withstand greater impact forces, and further extends its service life.

[0048] In this embodiment, the front and rear sides of the right end of the upper mold base 10 and the right ends of the two vertical plates 101 are all connected to support members 106; the front and rear ends of the upper mold base 10 are all provided with a first positioning groove 14 extending laterally, and the side of the two vertical plates 101 facing away from the buffer space 103 is provided with a second positioning groove 107 extending laterally. In this way, when it is moved by the external structure, it can be easily positioned and moved by the cooperation of the first positioning groove 14 with the support member 106 and the cooperation of the second positioning groove 107 with the support member 106.

[0049] In this embodiment, both the upper mold base 10 and the lower mold base 40 are rectangular structures. The four corners of the top of the lower mold base 40 are recessed with positioning holes, and sleeves 41 are embedded in the positioning holes. The four corners of the bottom of the upper mold base 10 are protruding with guide posts 13, and the guide posts 13 are adapted to the corresponding sleeves 41.

[0050] In summary, the key design feature of this utility model lies in the inclusion of a left-side core-pulling mechanism and a right-side core-pulling mechanism that can move laterally between the upper and lower mold bases. The left-side core-pulling mechanism comprises a left-side cylinder, a left-side linkage rod, a left-side slider, and a left-side core block connected in sequence. The left-side core block can move towards or away from the left side of the core protrusion. The right-side core-pulling mechanism comprises a right-side cylinder, a right-side linkage rod, a right-side slider, and a right-side core block connected in sequence. The right-side core block can move towards or away from the right side of the core protrusion. This allows for core pulling on both sides by driving the left-side core block with the left cylinder and the right-side core block with the right cylinder, respectively. This achieves a cylinder-driven core-pulling structure design, reducing space occupation. Furthermore, the cylinder-driven core-pulling structure does not require coordination with the upper mold movement, resulting in a simple and ingenious design that reduces subsequent maintenance and ensures the service life of the mold.
