Description

Technical Field

[0001] This utility model relates to the field of manufacturing aluminum pots for induction cookers, and in particular to a positioning fixture for electromagnetic induction heating elements. Background Technology

[0002] Existing aluminum pots for induction cookers generally consist of an aluminum pot body and an electromagnetic induction heating element (made of stainless steel or iron) attached to the bottom of the aluminum pot body. One current manufacturing process for aluminum pots for induction cookers involves first molding the electromagnetic induction heating element, then placing it into an aluminum pot molding mold and casting the aluminum pot body onto the heating element. Currently, the electromagnetic induction heating element is typically attached to the mold using an electromagnet. However, electromagnets are expensive and energy-intensive, which hinders cost reduction.

[0003] In view of the above problems, it is necessary to study an electromagnetic induction heating element positioning fixture, which is used to position and fit the electromagnetic induction heating element into the aluminum pot forming mold, with low cost and low energy consumption. Utility Model Content

[0004] The purpose of this utility model is to provide an electromagnetic induction heating element positioning fixture, which is used to position and fit the electromagnetic induction heating element into the aluminum pot forming mold, with low cost and low energy consumption.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An electromagnetic induction heating element positioning fixture includes a positioning plate and a positioning post; the positioning plate has a connecting part at its center and at least two positioning parts for positioning and engaging with the lower mold of an aluminum pot forming mold; the positioning post is used for inserting and engaging with the electromagnetic induction heating element and the upper mold of the aluminum pot forming mold, and the bottom of the positioning post forms a pulling part that engages and engages with the connecting part, and the pulling part is used for interference fit with the central sleeve of the electromagnetic induction heating element.

[0007] The outer side of the traction part of the positioning column has a traction cone surface, and the distance from the traction cone surface to the central axis of the positioning column gradually increases from top to bottom.

[0008] The top of the positioning post is equipped with a pull head.

[0009] The traction part of the positioning column is provided with a plug-in hole that engages with the connection part of the positioning plate.

[0010] The connecting part of the positioning plate is circumferentially limited to the insertion hole.

[0011] The inner wall of the insertion hole is provided with an insertion cone surface, and the distance from the insertion cone surface to the central axis of the positioning post gradually increases from top to bottom; the outer side of the connecting part is provided with a connecting cone surface that mates with the insertion cone surface, and the distance from the connecting cone surface to the central axis of the positioning plate gradually increases from top to bottom.

[0012] The positioning part of the positioning disk is a downwardly protruding columnar structure.

[0013] The positioning part of the positioning disk has a perforated structure.

[0014] The positioning disk also has at least one through hole.

[0015] The positioning disc and positioning column are made of metal.

[0016] After adopting the above solution, the electromagnetic induction heating element positioning fixture of this utility model is used to position and fit the electromagnetic induction heating element into the aluminum pot forming mold. Specifically, the following steps are taken: First, the pulling part of the positioning post is inserted and fitted with the connecting part of the positioning plate, and each positioning part of the positioning plate is positioned and fitted with the lower mold of the aluminum pot forming mold; second, the electromagnetic induction heating element is placed on the positioning plate, and the central sleeve of the electromagnetic induction heating element passes through the pulling part of the positioning post; then, the upper and lower molds of the aluminum pot forming mold are closed, so that the positioning post passes through the upper mold of the aluminum pot forming mold; finally, the upper mold of the aluminum pot forming mold is fitted with the lower mold of the aluminum pot forming mold... The clamps on the mold pull the positioning column upwards, ensuring a stable interference fit between the pulling part of the positioning column and the central sleeve of the electromagnetic induction heating element. Next, the upper and lower molds of the aluminum pot forming mold are separated, while the clamps on the upper mold of the aluminum pot forming mold continue to pull the positioning column upwards, thus separating the positioning plate from the electromagnetic induction heating element and the positioning column, while the positioning column and the electromagnetic induction heating element remain fitted in the upper mold of the aluminum pot forming mold. Finally, the positioning plate is removed. After this, the mold can be closed for casting. After casting is completed, applying force to the positioning column will cause the pulling part of the positioning column to detach from the electromagnetic induction heating element.

[0017] As can be seen from the above, the electromagnetic induction heating element positioning fixture of this utility model can be used to position and fit the electromagnetic induction heating element into the aluminum pot forming mold; moreover, the electromagnetic induction heating element positioning fixture of this utility model has few parts and low cost; in addition, the electromagnetic induction heating element positioning fixture of this utility model does not require a power supply during use and consumes little energy.

[0029] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0030] like Figures 1 to 5 As shown, this utility model discloses an electromagnetic induction heating element positioning fixture A, which includes a positioning disk 1 and a positioning post 2; wherein, the positioning disk 1 has a connecting part 11 at its center, and the positioning disk 1 has at least two positioning parts 12 for positioning and cooperating with the lower mold C2 of the aluminum pot forming mold C; the positioning post 2 is used to insert and cooperate with the electromagnetic induction heating element B and the upper mold C1 of the aluminum pot forming mold C, and the bottom of the positioning post 2 forms a pulling part 21 that inserts and cooperates with the connecting part 11, and the pulling part 21 is used to interference fit with the central sleeve B1 of the electromagnetic induction heating element B.

[0031] The electromagnetic induction heating element positioning fixture A of this utility model is used to position and fit the electromagnetic induction heating element B into the aluminum pot forming mold C. Figure 5As shown, the specific method is as follows: First, the pulling part 21 of the positioning post 2 is inserted and engaged with the connecting part 11 of the positioning plate 1, and each positioning part 12 of the positioning plate 1 is positioned and engaged with the lower mold C2 of the aluminum pot forming mold C; second, the electromagnetic induction heating element B is placed on the positioning plate 1, and the central sleeve B1 of the electromagnetic induction heating element B passes through the pulling part 21 of the positioning post 2; then, the upper mold C1 and the lower mold C2 of the aluminum pot forming mold C are closed, so that the positioning post 2 passes through the upper mold C1 of the aluminum pot forming mold C; next, the positioning post 2 is pulled upward by the clamp (not shown) engaged on the upper mold C1 of the aluminum pot forming mold C, so that the positioning post 2 passes through the lower mold C2 of the aluminum pot forming mold C. The pulling part 21 of the positioning plate 2 is stably interference-fitted with the central sleeve B1 of the electromagnetic induction heating element B. Next, the upper mold C1 and lower mold C2 of the aluminum pot forming mold C are separated, and simultaneously, the clamps on the upper mold C1 of the aluminum pot forming mold C pull the positioning post 2 upwards, thereby separating the positioning plate 1 from the electromagnetic induction heating element B and the positioning post 2, while the positioning post 2 and the electromagnetic induction heating element B remain fitted in the upper mold C1 of the aluminum pot forming mold C. Finally, the positioning plate 1 is removed. Afterwards, the mold can be closed for casting. After casting, applying force to the positioning post 2 will cause the pulling part 21 of the positioning post 2 to detach from the electromagnetic induction heating element B. As can be seen from the foregoing, the electromagnetic induction heating element positioning fixture A of this invention can be used to position and fit the electromagnetic induction heating element B into the aluminum pot forming mold C; moreover, the electromagnetic induction heating element positioning fixture A of this invention has few parts and low cost; furthermore, the electromagnetic induction heating element positioning fixture A of this invention does not require a power supply during use, resulting in low energy consumption.

[0032] In the embodiments of this utility model, the positioning disk 1 and the positioning post 2 are made of metal, which makes the positioning disk 1 and the positioning post 2 strong and have a long service life.

[0033] In an embodiment of this utility model, the outer side of the pulling part 21 of the positioning post 2 has a pulling cone surface 211, and the distance from the pulling cone surface 211 to the central axis of the positioning post 2 is gradually increased from top to bottom; this arrangement facilitates the smooth insertion of the pulling part 21 of the positioning post 2 into the central sleeve B1 of the electromagnetic induction heating element 2.
