Description

Technical Field

[0001] The utility model relates to the technical field of die-casting mold cores, in particular to a mold structure for an electric control housing. Background Art

[0002] When producing electronic control housings, the mold requires multiple core pulling parts to assist in product molding, making the mold structure too bloated. Too many core pulling structures will greatly increase the cost of the mold. At the same time, since a hole is required on the electronic control housing, it is impossible to set up an extra core pulling structure there. In order to solve the above problems, the mold structure needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a mold structure for an electronic control housing, which has the characteristics of reducing mold cost, streamlining mold structure, improving production efficiency, etc.

[0004] The technical solution adopted by the utility model to solve its technical problems is: providing a mold structure for an electronic control shell, including an upper mold core, a lower mold core and a gate structure, the upper mold core and the lower mold core are arranged in an upper and lower stacked arrangement, and a mold cavity structure is formed therebetween, a sealing ring surrounding the mold cavity structure is installed between the upper mold core and the lower mold core, the gate structure is embedded in the front of the upper mold core, a runner structure is provided between the rear side of the lower end of the upper mold core and the mold cavity structure, a combined core-pulling structure with a front end inserted into the mold cavity structure is installed at the rear between the upper mold core and the lower mold core, a left-slanted core-pulling structure is installed on the left side of the combined core-pulling structure, and a right-slanted core-pulling structure is installed on the right side of the combined core-pulling structure.

[0005] In this technical solution, a sealing ring is provided to ensure the sealing degree of the mold cavity structure and to improve the sealing degree of the upper mold core and the lower mold core. A combined core-pulling structure is installed to ensure a streamlined mold structure, facilitate the arrangement of the core-pulling structure, and reduce the manufacturing cost of the mold.

[0006] As a supplement to the present technical solution, the combined core-pulling structure includes a central docking bracket, a side bracket and an oblique core-pulling structure. There are two central docking brackets arranged side by side on the left and right. The front end of the central docking bracket is fixedly installed on the lower mold core, and two side brackets are symmetrically installed on the outside of the central docking bracket. The rear end of the central docking bracket is installed with a mounting block with the upper end tilted forward, and the mounting block is installed with a tilted oil cylinder with the front end tilted downward. The main shaft of the tilted oil cylinder is installed with an oblique core-pulling structure inserted into the mold cavity, and a rear block is installed between the rear end of the side bracket and the central docking bracket. The rear block is installed with a longitudinal left oil cylinder or right oil cylinder, and the main shaft of the left oil cylinder is installed with a left core-pulling structure inserted into the mold cavity, and the main shaft of the right oil cylinder is installed with a right core-pulling structure inserted into the mold cavity.

[0007] In this technical solution, a middle docking bracket is provided to facilitate the installation of the oblique core pulling, and upper side brackets are installed on both sides of the middle docking bracket to provide installation space for the left cylinder and the right cylinder, so that the three core pullings can be combined together. At the same time, the oblique core pulling and the left cylinder and the right cylinder are staggered, which reduces the overall volume of the core pulling, saves space inside the mold, reduces the overall volume of the mold, and saves the cost of the entire mold.

Several elastic pads are installed side by side between the pin baffle and the hole pin mounting block, and pads are installed between the elastic pads.

[0009] Conventional hole pins are directly inserted into the mold cavity structure, while this technical solution uses a sealing ring to improve the sealing degree of the mold cavity structure. When the vacuum operation is performed, the flow rate of the molten metal in the mold cavity structure is very fast, with a large impact force, and the conventional independent hole pins tend to shift when impacted, and the shifted hole pins will cause the hole position to shift.

[0013] As a supplement to the present technical solution, two exhaust block assemblies are symmetrically installed on both sides of the rear of the mold cavity structure. The exhaust block assemblies are used to facilitate the discharge of internal gas and also have an overflow effect. When the vacuum structure stops working, excess molten metal can be collected in the exhaust block assembly.

[0014] As a supplement to the present technical solution, a plurality of slag bag structures are provided on the rear side of the mold cavity structure, and a rear flow channel communicating with the slag bag structure is provided on the rear side of the slag bag structure.

[0015] In this technical solution, a rear flow channel is provided to facilitate centralization of the exhaust structure.

[0016] As a supplement to this technical solution, two vacuum pumping components are symmetrically installed at both ends of the rear side of the mold cavity structure, and the two ends of the rear flow channel are connected to the two vacuum pumping components. The vacuum pumping components are set to extract the internal air.
