AI Technical Summary
Traditional casting molds are prone to loosening and deformation in high-temperature environments, resulting in unstable cavity dimensions, which affects the accuracy of castings. Furthermore, the assembly error of ordinary metal molds increases after long-term use.
The system employs a standardized four-corner pin assembly and a mechanical linkage structure between the diagonal bracing pin and the push rod. Combined with coolant pressure, it achieves multi-point support for ejection, reducing stress concentration and ejection damage.
High-precision assembly was achieved, and assembly errors were controlled within a manageable range, thereby improving the dimensional stability and accuracy of the castings.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds, specifically a high-precision metal casting mold. Background Technology
[0002] Traditional casting molds face numerous technical bottlenecks in the production process:
[0003] Existing casting molds mostly use bolt connections or welding to fix multi-layer plates, but in high-temperature environments, they are prone to loosening, deformation, or inconsistent thermal expansion, resulting in unstable cavity dimensions and affecting casting precision. Ceramic molds also suffer from dimensional instability due to material deformation at high temperatures, affecting casting precision. Ordinary metal molds are also prone to increased assembly errors after long-term use. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision metal casting mold to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-precision metal casting mold includes a first plate, a second plate installed at the bottom of the first plate, a third plate installed at the end of the second plate away from the first plate, a fourth plate installed at the end of the third plate away from the second plate, a square iron base plate fixedly connected to the bottom of the fourth plate, and a base plate installed at the bottom of the inner frame of the fourth plate. Connectors are fixedly connected to the upper left and right sides of the base plate. Diagonal bracing pins are installed inside the frames of the connectors. A fixed mold table is installed on the top of the diagonal bracing pins. A push rod is provided on one side of the connector, and the bottom of the push rod is fixedly connected to the upper part of the base plate.
[0007] As a further embodiment of this utility model: a sealing post is provided on the side of the push rod away from the connector, and a water pipe II is connected to the top of the sealing post, and a fixed mold base is installed on the top of the water pipe II.
[0008] As a further improvement of this utility model: a feeding seat is installed at the center of the top of the plate, a channel is installed at the bottom of the feeding seat, and connecting pipes are installed on the left and right sides of the bottom of the channel.
[0009] As a further improvement of this utility model: the number of connecting pipes is two sets, and a dispersing pipe is installed at the bottom of the two sets of connecting pipes.
[0010] As a further improvement of this utility model: a water pipe is installed in the inner frame of the plate three.
[0011] As a further improvement of this utility model, each of the four corners of the first, second, third and fourth plates is equipped with a pin.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model achieves high-precision assembly through the standardized matching of the four corner pins and the plate layers, keeping the assembly error within a controllable range, which is significantly better than the error that exists after traditional bolt connection.
[0014] This utility model achieves multi-point support and ejection by mechanically linking the diagonal bracing pin and the push rod, utilizing the structure of the push rod fixed to the base plate at the bottom, combined with coolant pressure or a hydraulic system, thereby reducing stress concentration and ejection damage.
