Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0026] refer to Figure 1-7 , a motor shell lost foam mold with an insert quick-change structure, including a mold body 1, a mold cavity is opened on the bottom wall of the mold body 1, and an installation slot 2 is opened on the top wall of the mold body 1, and the installation plug The bottom of the groove 2 is provided with a matching hole 3, and the inside of the installation slot 2 is inserted with a fixed block 4, and the bottom of the fixed block 4 is connected with a bump 5, which is an insert, which plays a role when the motor casing is formed. To promote the formation of the tank body, a pull ring is connected to the top wall of the fixed block 4, and a mov...

The invention discloses a motor shell expendable mold with an insert quick-change structure. The motor shell expendable mold comprises a mold body, wherein a mold cavity is formed in the bottom wall of the mold body; a mounting slot is formed in the top wall of the mold body, a matching hole is formed in the bottom of the mounting slot, and a fixing block is inserted into the mounting slot; and the bottom of the fixing block is connected to a lug, a movable groove is formed in the inner side wall of one side of the mounting slot, and a tray is arranged in the movable slot. According to the motor shell expendable mold, a detaching and replacing structure of an insert of the motor shell expendable mold is redesigned, when the insert is installed, only the insert needs to be tightly plugged into the matching hole until a clamping hook is clamped on a lap joint so that the insert can be fixed; and when the insert is detached, only the insert needs to be pressed to the bottom again, the clamping hook can be separated from the lap joint, the insert can be popped out under the action of tension springs, then the insert can be quickly taken out, the detaching and replacing speed of the expendable mold insert is greatly improved, and the detaching and replacing time is shortened.
Description
technical field [0001] The invention relates to the technical field of lost foam for motor casings, in particular to a lost foam mold for motor casings with a quick-change structure for inserts. Background technique [0002] Lost foam casting (also known as solid casting) is a solid casting of foam plastic molds using dry sand without binders combined with vacuum pumping technology. It is a combination of foam models similar in size and shape to the castings into model clusters, and brushed with refractory coatings. After being dried, it is buried in dry quartz sand for vibration molding, poured under negative pressure to vaporize the model, liquid metal occupies the position of the model, solidifies and cools to form a new casting method. Compared with traditional casting technology, lost foam casting has the following characteristics: good casting quality and low cost; unlimited materials, suitable for all sizes; high dimensional accuracy, smooth surface; less cleaning and...
