Since the foam structure of the lost foam has buoyancy, manual force is required to press it down for dipping and coating, which is extremely labor-intensive and inefficient. Some larger molds require two people to operate collaboratively. If incomplete dipping occurs at the ends and sides of the lost foam, the quality of the casting will be affected.

[0018] 4. The fixed mold structure can clamp multiple lost foams at equal distances between the first and second support plates, and complete the processing of both end faces of multiple molds through a single dipping process; manual operation can only process one mold body at a time, and the production efficiency difference is significant. The open design with no obstructions at the front and rear ends of the equipment supports two people to load and unload materials simultaneously or connect to automatic loading and unloading equipment, realizing the "loading-dipping-unloading" assembly line operation and improving work efficiency.

[0019] 5. The unobstructed design of the front and rear ends of the equipment supports both manual two-person collaborative loading and unloading, and can also be connected to automated robotic arms to adapt to different production capacity requirements; traditional manual operation is difficult to integrate with automated equipment, limiting capacity upgrades; by adjusting the spacing of the fork arm connecting rod assembly and the driving stroke of the screw rod, the device is compatible with lost foam of different sizes, not only for gearboxes, but also for pump housings, etc. Manual operation requires adjustment of techniques for different mold bodies, and has poor adaptability.

[0037] More specifically, the equidistant clamping and synchronous action, the reverse thread design at both ends of the spiral rod 38 ensure that the second support plates 33 on both sides move equidistantly, the clamping is error-free, and multiple lost foams can be clamped at the same time (the number of clamping is set according to the number of second support plates 33 according to actual needs). The leakage groove 4 is designed to allow the paint to penetrate the bottom of the mold body during dipping, and cooperate with the clamping wheel 34 to reduce the contact area with the lost foam.

[0040] As a further solution of the present invention, in order to achieve synchronous dipping of multiple lost foams, the second support plate 33 is moved equidistantly relative to the first support plate 31 for clamping.

[0041] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0042] Working principle:

[0043] The equipment is moved by the wheels 12 on the lower wall of the vehicle body 11 in the main structure 1 to the dipping box, and the mold structure 3 is positioned above the dipping box;

[0044] The cast gear 23 box lost foam mold is placed between the first support plate 31 and the second support plate 33, and between the second support plate 33 and the second support plate 33; the motor 37 in the chassis 36 in the solid mold structure 3 is started to drive the screw rod 38 to rotate with the help of the bearing 5 in one of the adapter seats 35. Since the adapter seat 35 provided on the top second support plate 33 is screwed to the screw rod 38, and the second support plate 33 and the first support plate 31 are connected in series through the symmetrically provided fork arm connecting rod assembly 32, the top second support plate 33 is forced to descend, and the linkage of the fork arm connecting rod assembly 32 is used to realize the equidistant descending movement of the second support plate 33, thereby equidistantly clamping the same lost foam;

[0045] The hydraulic cylinder 173 in the turning assembly 17 is activated, and the turning seat 172 is turned 90 degrees on the turning frame 171 by the extension of the hydraulic cylinder 173, so that the lost foam after the longitudinal arrangement is turned 90 degrees to the horizontal arrangement;

[0046] The translation slide 13 drives the lost foam to move laterally to adjust the position for calibrating the dipping box. When the translation slide 13 is started, the roller 15 of the bearing seat 14 contacts and rolls with the vehicle body 11 to provide support force, driving the lifting slide 16 to move. Then the lifting slide 16 is started to lower the laterally arranged lost foam into the dipping box.

[0047] The lost mold has a certain size. In order to prevent damage caused by buoyancy and to prevent a large amount of liquid from entering the mold body and affecting the pouring of the dipping liquid, the active slide 25 in the reversing structure 2 is started. The active slide 25 drives the tooth arm 26 to move horizontally, and the translation movement of the tooth arm 26 is engaged with the gear 23, so that the gear 23 is forced to rotate with the help of the reversing shaft 22; then the reversing shaft 22 drives the fixed mold structure 3 on the docking frame 24 to rotate. Since the rotation range of the reversing shaft 22 is 180 degrees, the two ends of the lost mold can be turned toward Corresponding to the bottom, the rotation of the reversing shaft 22 is used to realize the face change of the two ends of the lost foam, and the two ends are respectively inserted into the dipping process; and because the first support plate 31 and the second support plate 33 clamp the lost foam, it is not directly blocked by a large area of ​​contact between the plate surfaces, but by point-surface contact with the clamping wheel 34, and after dipping, the leakage groove 4 on the first support plate 31 and the second support plate 33 can effectively promote the flow of the dipping liquid; and after dipping, the lost foam is unloaded, and the residual dipping liquid on the lost foam automatically flows down from the top to make up for the contact position of the clamping wheel 34.

[0048] In summary, the mechanical linkage of the present invention replaces manual operation, automatically completes the reversing, flipping and downward pressure dipping of the lost foam, completely replaces the manual flipping action, improves the efficiency of dipping multiple molds in a single batch, saves manpower and time, prevents omission of the dipping surface or uneven coating thickness due to different mold shapes, and prevents uneven damage due to manual force applied by buoyancy. It is suitable for molds of multiple specifications and processes, and the device is compatible with lost foams of different sizes.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
