Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a model forming and processing mold. Background Technique

[0002] A mold is a tool used to make formed objects. Generally, a mold consists of two parts: a moving mold and a fixed mold. The two can be separated and combined. When separated, the workpiece is taken out, and when combined, the blank is injected into the mold cavity for forming. A mold is a precision tool with a complex shape and has high requirements for structural strength, stiffness, surface hardness, surface roughness, and machining accuracy. The development level of mold production is one of the important indicators of the mechanical manufacturing level.

[0003] Molds can be used to produce models. There are multiple cooling water pipe joints on the outside of the mold. When the mold is not in use, it is possible for small-volume objects to pass through the cooling water pipe joints and enter the inside of the cooling water pipes. The above situation will cause the cooling water pipes to be blocked, and the blockage of the cooling water pipes will cause the mold to malfunction. Therefore, a model forming and processing mold is needed to solve the above problems. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a model forming and processing die as shown in Figures 1-4 Figure 5, which includes a die body 1. Two shielding mechanisms 2 are provided on the outer wall of the die body 1. The shielding mechanisms 2 are used to prevent small-volume objects from passing through the cooling water pipe joints and entering the interior of the cooling water pipes. The two shielding mechanisms 2 act on the cooling water pipe joints at the moving die and the fixed die respectively, and the structures of the two shielding mechanisms 2 are the same;

[0024] The shielding mechanism 2 includes a storage box 201. The storage box 201 is fixedly connected to the front of the die body 1. A strip-shaped hole is opened on one side of the storage box 201. A rotating hole is opened at the bottom of the inner wall of the storage box 201. A winding rod 202 is arranged in the inner cavity of the rotating hole. The bottom end of the winding rod 202 is rotatably connected to the inner cavity of the rotating hole. A clockwork spring 203 is arranged between the winding rod 202 and the rotating hole. The clockwork spring 203 is used to drive the winding rod 202 to automatically perform a reset rotation, improving the convenience of operation. The clockwork spring 203 is fixedly connected between the rotating hole and the winding rod 202. A shielding belt 204 is arranged in the inner cavity of the strip-shaped hole. The width of the shielding belt 204 is greater than the diameter of the cooling water pipe joint. A notch groove is opened on the inner wall of the storage box 201. A cylindrical roller 209 is rotatably connected in the inner cavity of the notch groove. The cylindrical roller 209 plays a role in protecting the shielding belt 204, avoiding direct contact and friction between the shielding belt 204 and the inner wall of the storage box 201. One side of the shielding belt 204 is fixedly connected to the outer wall of the winding rod 202. The other side of the shielding belt 204 is fixedly connected with a plurality of connecting rods 207 at equal intervals. One ends of the plurality of connecting rods 207 are fixedly connected with a traction rod 208. The traction rod 208 facilitates the staff to apply force to drive the shielding belt 204 to unfold. Two retaining rings 5 are arranged in the inner cavity of the storage box 201. The two retaining rings 5 play a role in limiting the shielding belt 204. The two retaining rings 5 are symmetrically and fixedly sleeved on the outer wall of the winding rod 202. Arc-shaped grooves are symmetrically opened on the outer wall of the die body 1. The inner wall of the arc-shaped groove is a smooth arc surface. The arc-shaped groove plays a role in protecting the shielding belt 204, avoiding direct contact and friction between the shielding belt 204 and the bending part of the die. A first magic tape 205 is arranged on the back of the die body 1. The first magic tape 205 is fixedly connected to the back of the die body 1. A second magic tape 206 is arranged on the back of the first magic tape 205. The first magic tape 205 and the second magic tape 206 play a role in positioning the unfolded shielding belt 204. The second magic tape 206 is fixedly connected to the outer wall of the shielding belt 204;

[0025] The top end of the winding rod 202 penetrates through the top of the inner wall of the storage box 201 and is fixedly connected to a turntable 3. The turntable 3 enables the staff to apply force to drive the winding rod 202 to rotate. Restricting the rotation of the turntable 3 can restrict the rotation of the winding rod 202. A threaded hole is formed in the top of the turntable 3, and a locking bolt 4 is threadedly connected to the inner wall of the threaded hole. The locking bolt 4 rotated clockwise will gradually enter the locking hole, and the locking bolt 4 rotated counterclockwise will gradually disengage from the locking hole. The locking bolt 4 and the locking hole are used to prevent the winding rod 202 from rotating. A locking hole is formed in the top of the storage box 201, and the bottom end of the locking bolt 4 is movably sleeved in the inner cavity of the locking hole.

[0026] The working principle of the present utility model:

[0027] After the model is produced using the mold, apply a counterclockwise turning force to the locking bolt 4. When the locking bolt 4 is completely separated from the locking hole, apply a force to the traction rod 208. The traction rod 208 will drive the shielding belt 204 to gradually unfold. Then, arrange the shielding belt 204 along the two arc-shaped grooves. During this process, the shielding belt 204 will cover the cooling water pipe joint. Finally, stick the second magic tape 206 on the shielding belt 204 to the first magic tape 205 on the mold, and the unfolding work of the shielding mechanism 2 can be completed. When both shielding mechanisms 2 are unfolded according to the above steps, the cooling water pipe joints at the moving mold and the fixed mold of the mold can be shielded, effectively preventing small objects from passing through the cooling water pipe joint and entering the inside of the cooling water pipe, ensuring the smoothness of the cooling water pipe of the mold;

[0028] When it is necessary to use the mold to produce the model again, separate the first magic tape 205 and the second magic tape 206. At this time, the shielding belt 204 will automatically wind up on the winding rod 202 under the action of the clockwork spring 203. Then, rotate the locking bolt 4 clockwise. When the bottom end of the locking bolt 4 enters the locking hole, the reset work of the shielding mechanism 2 is completed. Before the mold is put into use, the reset work of both shielding mechanisms 2 needs to be completed.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
