Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and in particular to a square guide structure for die casting molds. Background Technology

[0002] Die casting molds are metal molds used for pressure casting. In the die casting process, liquid or semi-liquid metal is filled into the mold cavity under high pressure and then rapidly solidified under pressure to obtain the casting. Die casting molds are usually installed on die casting machines and are subjected to high temperature and high pressure during the die casting process. This process has the advantages of high production efficiency, high precision and high surface quality, and is suitable for mass production of small, complex and precision metal parts.

[0003] Most existing die-casting molds use circular guide pillars as their guiding structure. However, the strength of circular guide pillars is relatively weak, especially in some large die-casting molds where the strength of the guide pillars also has certain requirements. In addition, if there is a gap between the guide pillar and the guide groove during guidance, the circular guide pillar is not easy to adjust. Utility Model Content

[0004] The main objective of this invention is to provide a square guide structure for die-casting molds, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A square guide structure for die casting mold includes a lower mold, an upper mold mounted on the upper end of the lower mold, a locking module mounted on the left and right ends of both the lower mold and the upper mold, a set of locking pins mounted on the lower end of the lower mold and the upper end of the upper mold, the number of locking pins in both sets being six, and a hydraulic cylinder bracket mounted on the left and right ends of the upper mold.

[0007] Preferably, the upper end of the lower mold has four square guide grooves, each containing a set of slots, and each of the four sets of slots contains two guide blocks. The guide blocks are engaged in the slots, allowing them to be quickly replaced or removed for polishing as needed. Additionally, locking modules are installed at the left and right ends of both the upper and lower molds. These locking modules connect the upper and lower molds together using screws, preventing separation during transport.

[0008] Preferably, the upper mold has four fixing slots at its lower end, and a square guide post is fixedly installed in each of the four fixing slots. A guide block is also engaged in the slot on the square guide slot. When the square guide post is engaged in the square guide slot, the guide block limits its movement, thereby guiding the upper mold.

[0009] Preferably, the square guide post and the square guide groove are vertically aligned.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Four square guide pillars are fixedly installed in the four fixed slots on the upper mold. The four square guide pillars cooperate with the four square guide slots on the lower mold. Guide blocks are also engaged in the slots on the square guide slots. When the square guide pillars are engaged in the square guide slots, the guide blocks limit the movement, thereby guiding the upper mold. Moreover, the square shape of the guide pillars is stronger than that of round guide pillars. The guide blocks are engaged in the slots, which allows the guide blocks to be quickly replaced or removed for grinding as needed. In addition, locking modules are installed on the left and right ends of the upper and lower molds. The locking modules are fixed together by screws to prevent the upper and lower molds from separating during transportation. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1-3 As shown, a square guide structure for die casting mold includes a lower mold 1, an upper mold 2 installed on the upper end of the lower mold 1, a locking module 5 installed on the left and right ends of both the lower mold 1 and the upper mold 2, a set of locking pins 3 installed on the lower end of the lower mold 1 and the upper end of the upper mold 2, and six locking pins 3 in each set. A hydraulic cylinder bracket 4 is installed on the left and right ends of the upper mold 2.

[0020] The lower mold 1 has four square guide grooves 10 on its upper end. Each of the four square guide grooves 10 contains a set of slots 11, and each of the four sets of slots 11 contains two guide blocks 12. The guide blocks 12 are engaged in the slots 11, allowing the guide blocks 12 to be quickly replaced or removed for grinding as needed. In addition, locking modules 5 are installed on the left and right ends of the upper mold 2 and the lower mold 1. The locking modules 5 are fixed together by screws to prevent the upper mold 2 and the lower mold 1 from separating during transportation.

[0021] The upper mold 2 has four fixing slots 20 at its lower end, and a square guide post 21 is fixedly installed in each of the four fixing slots 20; the square guide post 21 is vertically aligned with the square guide slot 10. A guide block 12 is also engaged in the slot 11 on the square guide slot 10. When the square guide post 21 is engaged in the square guide slot 10, it is limited by the guide block 12, thereby achieving the purpose of guiding the upper mold 2.

[0022] It should be noted that this utility model is a square guide structure for die casting molds. Locking modules 5 are installed on the left and right ends of the upper mold 2 and the lower mold 1. The locking modules 5 are connected to the upper mold 2 and the lower mold 1 by screws to prevent the upper mold 2 and the lower mold 1 from separating during transportation. Moreover, square guide posts 21 are fixedly installed in the four fixing slots 20 on the upper mold 2. The four square guide posts 21 are in conjunction with the four square guide slots 10 on the lower mold 1. Furthermore, guide blocks 12 are engaged in the slots 11 on the square guide slots 10. When the square guide posts 21 are engaged in the square guide slots 10, they are limited by the guide blocks 12, thereby achieving the purpose of guiding the upper mold 2. Moreover, the guide posts are square in shape, which is not only stronger than round guide posts, but also allows the guide blocks 12 to be quickly replaced or removed for grinding as needed.
