Description

Technical Field

[0001] The utility model relates to the technical field of mold positioning mechanisms for injection molding, in particular to a mold positioning mechanism for injection molding of an engine oil pan. Background Art

[0002] As an automotive accessory, the engine oil pan has the main function of being installed under the car engine and serving as the outer shell of the oil storage tank to prevent impurities from entering, and to collect and store the lubricating oil flowing back from the friction surfaces of the diesel engine, dissipate some heat, and prevent the lubricating oil from oxidizing. In the existing production of the engine oil pan, that is, in the injection molding process, it is often necessary to close two sets of molds and inject molten plastic into the interior of the mold. When the plastic inside the mold cools, the production of the engine oil pan is completed. During the use of the mold for injection molding of the engine oil pan, a positioning mechanism is often required to confirm the position of the mold for injection molding of the engine oil pan to prevent the position from shifting when the mold is moved. However, the existing positioning mechanism for the mold for injection molding of the engine oil pan lacks a demoulding alarm component, and since the engine oil pan needs to cooperate with the automobile engine housing, its structure is relatively complex. Too fast demoulding often causes the engine oil pan to be damaged too quickly, thereby affecting the use effect of the positioning mechanism for the mold for injection molding of the engine oil pan.

[0003] Compared with the existing mold positioning mechanism for engine oil pan injection molding, the utility model adds a demoulding alarm component. When the demoulding speed is too fast, the engine oil pan will be damaged due to its more complex grooves and protrusions, which can remind surrounding staff to debug the transmission components of the mold, thereby improving the use effect of the mold positioning mechanism for engine oil pan injection molding.
