Description

Technical Field

[0001] This utility model specifically relates to the field of automotive mold technology, and more specifically to a sliding opening and closing top-discharge type automotive mold. Background Technology

[0002] Automotive molds are a general term for molds used to manufacture all parts of a car, including injection molds, forging molds, stamping molds, and casting molds. Injection molds are mainly used to produce plastic parts for automotive interiors and exteriors, such as dashboards, bumpers, and door panels. Molten plastic is injected into the mold cavity, and after cooling and solidification, it forms the desired part shape. Casting molds, including casting wax models, are used to manufacture castings such as engine blocks, cylinder heads, and wheel hubs. A mold similar in shape to the part is first made, then molten metal is poured into the mold, and after cooling and solidification, the casting is formed.

[0003] However, in practice, it has been noted that some hollow parts require further processing of the internal hollow areas after injection molding to remove excess material from the inside of the workpiece. This necessitates secondary or tertiary processing of the workpiece, resulting in numerous production steps and reduced production efficiency. Furthermore, injection molds inevitably wear down after a period of use, requiring timely disassembly for internal maintenance or replacement to ensure processing accuracy. Replacement takes considerable time, which also affects the processing efficiency of the workpiece. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-10 This utility model provides a sliding opening and closing top discharge type automobile mold, including a frame body 1. Support columns 2 are fixedly connected in a rectangular array on the top of the frame body 1, and a top fixing plate 3 is fixedly connected to the other end of the support columns 2. A connecting pressure plate 5 is provided between the frame body 1 and the top fixing plate 3, and an opening and closing mold 6 is provided between the connecting pressure plate 5 and the frame body 1.

[0035] Both ends of the opening and closing mold 6 are fixedly connected with quick-connect seats 7. The opening and closing mold 6 includes a top mold 61 connected to the connecting pressure plate 5 and a bottom mold 62 connected to the frame body 1. The quick-connect seats 7 are located between the connecting pressure plate 5 and the top mold 61, and between the frame body 1 and the bottom mold 62.

[0036] The top mold 61 is provided with a sliding mold core 64, and each sliding mold core 64 is fixedly connected to an inclined slide block 65 at its end. The inclined slide block 65 is inclined at the end away from the sliding mold core 64, and the bottom mold 62 is provided with an inclined groove 63 corresponding to the inclined slide block 65.

[0037] By adopting the above technical solution, during the mold closing process of the top mold 61 and the bottom mold 62, the inclined surface of the sliding mold core 64 and the inclined surface of the inclined groove 63 cooperate with each other, which can push the sliding mold core 64 to move inward, so that the inner side of the top mold 61 and the bottom mold 62 and the sliding mold core 64 form a cavity, thereby forming a hollow part in one step, and eliminating the need for drilling the interior after forming, saving processing steps in the processing of automotive parts, and thus improving production efficiency.

[0038] Furthermore, the quick-connect seat 7 includes a mounting top seat 71 that is fixedly connected to the frame body 1 and the connecting pressure plate 5 respectively, and a fixed base 72 that is fixedly connected to the top mold 61 and the bottom mold 62, and the mounting top seat 71 and the fixed base 72 are interlocked.

[0039] Furthermore, the mounting top seat 71 includes a protruding bracket 711. The protruding bracket 711 has positioning protrusions arranged in a ring array below it. Each positioning protrusion has a receiving groove 713 on its side, and the receiving groove 713 has an integrally formed disassembly slot 714 near the outside of the protruding bracket 711 on its side.

[0040] More specifically, the fixed base 72 includes a connecting base plate 721, on which arc-shaped locking blocks 722 are arranged in a circular array to engage with positioning protrusions, and the positioning protrusions are staggered with the connecting base plate 721.

[0041] Furthermore, the arc-shaped locking block 722 has a triangular locking groove 723 on the side near the storage groove 713, and each storage groove 713 is movably connected to a locking spring 74, and the other end of the locking spring 74 engages with the triangular locking groove 723.

[0042] Furthermore, a metal spring 77 is fixedly connected to the side of the locking spring 74 near the receiving groove 713, and the other end of the metal spring 77 is fixedly connected to the receiving groove 713.

[0043] One end of the locking spring 74 is fixedly connected to a rotating lever 75 corresponding to the disassembly slot 714, and the end of the rotating lever 75 extends to the side of the protruding seat 711.

[0044] By adopting the above technical solution, the protrusions on the protruding card holder 711 and the arc-shaped card block 722 are spaced apart, which can play a positioning role when the protruding card holder 711 and the connecting base plate 721 are installed. After insertion, the metal spring 77 will push the end of the locking spring tongue 74 into the storage groove 713, thereby quickly connecting the mounting top seat 71 and the fixed base 72, which facilitates the quick installation of the opening and closing mold 6, shortens the installation time, and improves the replacement efficiency.

[0045] More specifically, both ends of the protruding card holder 711 are integrally provided with limiting protrusions 712, and an outer rotating ring 73 is movably connected between the two limiting protrusions 712. The outer rotating ring 73 is provided with connecting grooves 76 in a ring array corresponding to the rotating lever 75, and the end of the rotating lever 75 slides in cooperation with the connecting grooves 76.

A sliding upright is fixedly connected above the connecting pressure plate 5, and the top end of the sliding upright slides in cooperation with the top fixing plate 3.

[0047] By adopting the above technical solution, rotating the outer rotating ring 73 causes the rotating lever 75 to move closer to the receiving groove 713 via the connecting slide groove 76 on the outer rotating ring 73. The rotating lever 75 moves to the inside of the disassembly slot 714. At this time, the rotating lever 75 will drive the end of the locking tongue 74 to move from the inside of the triangular slot 723 to the inside of the receiving groove 713. Then, the mounting top seat 71 is moved upward, thereby quickly separating the mounting top seat 71 and the fixed base 72, and thus quickly disassembling the opening and closing mold 6.

[0048] Furthermore, the inclined slide 65 has a T-shaped cross-section, and the inner side of the top mold 61 is provided with a sliding groove corresponding to the inclined slide 65, ensuring that the inclined slide 65 can drive the sliding mold core 64 to slide inside the top mold 61. The top mold 61 can be used to hollow out the inside of the workpiece, thus shortening the time consumption for secondary processing.

[0049] Furthermore, the inner side of the storage groove 713 is provided with a shaft, and the end of the shaft passes through the lower part of the locking spring 74 and is interference-fitted with the protruding card seat 711 to ensure that the locking spring 74 can swing inside the storage groove 713.

[0050] The working principle of this utility model is as follows: In use, firstly, the top mold 61 and the bottom mold 62 are placed between the connecting pressure plate 5 and the machine frame 1, respectively. The fixed base 72 on the top mold 61 and the fixed base 72 on the bottom mold 62 are aligned with the mounting top seat 71 below the connecting pressure plate 5 and the mounting top seat 71 above the machine frame 1, respectively. Then, the mounting top seat 71 and the fixed base 72 are inserted together, with the protrusion on the mounting top seat 71 interlocking with the arc-shaped locking block 722 on the fixed base 72. Then, the metal spring 77 pushes the locking tongue. 74 moves closer to the arc-shaped locking block 722, so that the end of the locking spring tongue 74 engages with the triangular slot 723, thereby quickly locking the mounting top seat 71 and the fixed base 72. Then, the lifting cylinder 4 pushes the connecting pressure plate 5 downward, so that the top mold 61 and the bottom mold 62 move closer to each other. During the mold closing process, the inclined surface at the end of the sliding mold core 64 engages with the inclined surface inside the inclined groove 63, so that the sliding mold core 64 moves inward, which facilitates the production of hollow automotive parts. The structure is simple, the operation is very convenient, and the intensity of manual labor is effectively reduced.
