Description

Technical Field

[0001] This utility model relates to the field of mold frames, and in particular to a high-strength mold frame for injection molding machine production. Background Technology

[0002] In injection molding production, a corresponding mold base is required.

[0003] The mold frame, also known as the mold body, is the skeleton and base of the injection mold. It is the parasitic body of each part of the mold and the unprocessed assembly of the cavity. It is used to support and fix the required mold core.

[0004] However, in existing injection molding machine mold frames, the square iron and the base plate are fixed together with bolts. Once the bolts loosen, the square iron will loosen, which can easily create gaps between the square iron and the base plate. This can lead to impacts and damage during mold closing.

[0005] Therefore, it is essential to invent a high-strength mold base for injection molding machine production. Utility Model Content

[0011] The ejector plate is slidably connected to the T-shaped connecting block and the limiting guide rail;

[0012] The upper mold frame includes an A plate and a sprue plate. The A plate is fixed on the sprue plate, and a sliding sleeve corresponding to the guide post is installed on the A plate. The A plate is slidably connected to the guide post through the sliding sleeve.

[0013] The ejector plate has sliding grooves on both sides, and the ejector plate is slidably connected to the corresponding T-shaped connecting block and the limiting guide rail through the sliding grooves.

[0014] Several heat dissipation cavities are evenly formed on the connection surface between the square iron and the B plate, and the heat dissipation cavities are fixedly connected to the B plate.

[0015] A heat dissipation hole is provided through the square iron, and the heat dissipation hole is arranged perpendicular to the heat dissipation cavity. The heat dissipation hole is connected to the heat dissipation cavity and the notch.

[0020] The limiting guide rail has a through hole, which is connected to the heat dissipation hole.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] When the screws between the base plate and the square iron become loose, the positioning block and ejector plate can restrict the square iron, ensuring the stability and strength between the base plate and the square iron, and preventing gaps from forming between them.

[0032] Example

[0033] Reference Figure 1-4A high-strength mold frame for injection molding machine production includes a lower mold frame and an upper mold frame. The lower mold frame includes a base plate 1, an ejector plate 2, square irons 3, guide pillars 4, and a B plate 5. Positioning blocks are fixedly installed on both sides of the upper part of the base plate 1 to position the square irons 3, prevent the square irons 3 from loosening with the base plate 1, and ensure the stability and strength between the square irons 3 and the base plate 1. The positioning blocks on the base plate 1 are engaged with the two square irons 3. The base plate 1 is fixedly connected to the square irons 3 by bolts. An ejector plate 2 is slidably installed on the base plate 1. The ejector plate 2 is located between the two square irons 3 and is slidably connected with the two square irons 3 and the positioning blocks. Through the setting between the ejector plate 2 and the positioning blocks, the ejector plate 2 can block the square irons 3 to prevent them from falling off the positioning blocks, while not affecting the normal operation of the ejector plate 2.

[0034] In this embodiment, the square iron 3 is provided with a T-slot 31 and a notch 32. The T-slot 31 is below the notch 32, and the T-slot 31 and the notch 32 are connected so as to connect with the positioning block through the T-slot 31 and the notch 32.

[0035] In this embodiment, the positioning block includes a T-shaped connecting block 9, a stop block 10, and a limiting guide rail 11. The T-shaped connecting block 9 is fixedly installed on one side of the upper surface of the base plate 1.

The limiting guide rail 11 is fixedly installed above the T-shaped connecting block 9 so as to increase the contact distance between the limiting guide rail 11 and the ejector plate 2, so that the ejector plate 2 can always limit and block the square iron 3 during operation, ensuring the stability of the square iron 3 on the T-shaped connecting block 9. One side of the limiting guide rail 11 is flush with the end of the T-shaped connecting block 9 away from the stop block 10 so as to make stable contact with the ejector plate 2.

[0036] In this embodiment, the T-shaped connecting block 9 is inserted into the T-shaped groove 31, and the limiting guide rail 11 is inserted into the notch 32, so that the base plate 1 and the square iron 3 can be disassembled and assembled. At the same time, the T-shaped connecting block 9 and the notch 32 can fill the T-shaped groove 31 and the notch 32 to ensure the strength of the square iron 3.

[0037] In this embodiment, each side of the ejector plate 2 is provided with a sliding groove 21. The ejector plate 2 is slidably connected to the corresponding T-shaped connecting block 9 and the limiting guide rail 11 through the sliding groove 21, so as to ensure the stability between the ejector plate 2 and the positioning block and prevent the ejector plate 2 from being displaced.

[0038] In this embodiment, a plurality of heat dissipation cavities 33 are evenly provided on the connection surface between the square iron 3 and the B plate 5. The heat dissipation cavities 33 are fixedly connected to the B plate 5 so as to dissipate heat from the B plate 5, reduce the impact of heat on the B plate 5, and thus improve the strength of the B plate 5.

[0039] In this embodiment, a heat dissipation hole 34 is provided through the square iron 3. The heat dissipation hole 34 is arranged perpendicularly to the heat dissipation cavity 33. The heat dissipation hole 34 is connected to the heat dissipation cavity 33 and the notch 32 to allow air circulation and better heat dissipation.

[0040] In this embodiment, a plurality of microchannel heat dissipation flat tubes 51 corresponding to heat dissipation cavities 33 are uniformly arranged on the connection surface between plate B 5 and square iron 3. The microchannel heat dissipation flat tubes 51 are inserted into the corresponding heat dissipation cavities 33 so that plate B 5 can increase the contact area between itself and square iron 3 through the microchannel heat dissipation flat tubes 51 to transfer heat and achieve a better heat dissipation effect.

[0041] In this embodiment, cooling channels can be opened in both B plate 5 and A plate 6, and cooling holes 8 can be opened on both B plate 5 and A plate 6.

[0042] The cooling holes 8 on plate B5 are connected to the cooling channels on plate B5. The cooling channels on plate B5 are connected to each microchannel heat dissipation flat tube 51 so that the cooling medium can flow between the cooling channels and the microchannel heat dissipation flat tube 51.

[0043] In this embodiment, a through hole 12 is provided on the limiting guide rail 11, and the through hole 12 is connected to the heat dissipation hole 34 to allow air circulation and better heat dissipation.
