AI Technical Summary
During the mold production process, the air needle is small and complex in structure, and it is difficult to use a copper rod to knock out and remove it. The removal process is prone to damage the shape of the insert, resulting in the risk of not being able to be taken out.
A fixture including a base, a sliding pickup block, a connecting rod, a moving wheel and a handle is designed. The movement of the moving wheel, a connecting rod and a sliding pickup block is driven by the rotation of the handle to realize the removal of the air needle.
This fixture improves the efficiency of removing the air needle, avoids damage to the air needle, saves costs, and solves the risk of not being able to remove the air needle.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a fixture for an air extraction needle. Background Art
[0002] A mold cavity is composed of multiple mold inserts. Among these inserts, a part of the inserts are called air needles. As shown in Figure 3 , its function is to discharge the air in the mold cavity, making it more conducive to filling the rubber material. Most of these molds are connectors, with complex product structures and extremely high requirements. During the production process, the rubber material will generate gas, and these gases will condense and block the exhaust position of the air needles, thereby affecting the mold forming (these air needles are similar to air filters). Therefore, these air needles must be periodically cleaned to remove the gas. However, due to the small size of the air needle 7, especially the very small head, it cannot be knocked out with a copper rod because it is too small to have a force application point and will also damage the shape of the insert. Therefore, a fixture must be used to take out these air needles. Summary of the Invention
[0003] The purpose of the utility model is to provide a fixture for an air extraction needle to solve the above problems.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows: A fixture for an air extraction needle includes a base. On the base, a sliding extraction block, a connecting rod, a movable wheel, and a handle are sequentially arranged from left to right. Among them, one end of the sliding extraction block is provided with an extraction hook, and the other end is connected to one end of the connecting rod. On both sides of the sliding extraction block, sliding extraction block pressing strips for fixing the sliding extraction block are also provided. The other end of the connecting rod is connected to the movable wheel, and the movable wheel is fixedly connected to the handle. By rotating the handle, the movable wheel makes a circular motion.
[0005] As a preferred technical solution, the movable wheel is provided with a connecting portion for connecting with the connecting rod.
[0006] As a preferred technical solution, an inclined surface is provided on the base, and the movable wheel is arranged on the inclined surface. The inclined surface is to avoid the movement range of the connecting rod.
[0007] As a preferred technical solution, the sliding extraction block pressing strip is fixed to the base by bolts.
[0008] As a preferred technical solution, both ends of the connecting rod are respectively connected to the sliding extraction block and the movable wheel by bolts.
[0009] As a preferred technical solution, an oil groove is provided on the inner side of the sliding extraction block pressing strip, and by machining the oil groove on its inner side, the sliding extraction block can move back and forth smoothly.
[0010] Compared with the prior art, the advantages of the present utility model are as follows: The jig of the present utility model greatly improves the efficiency of the air extraction needle, can avoid damage to the air needle, saves costs at the same time, and also avoids the risk that the air needle cannot be taken out.

[0015] The present utility model will be further described below in conjunction with the accompanying drawings.
[0016] Embodiment:
[0017] Refer to Figure 1 , a jig for extracting an air needle, comprising a base 2, on which a sliding part-taking block 1, a connecting rod 4, a movable wheel 5 and a handle 6 are sequentially arranged from left to right. Among them, one end of the sliding part-taking block 1 is provided with a part-taking hook 11, and the other end is connected to one end of the connecting rod 4. On both sides of the sliding part-taking block 1, there are also sliding part-taking block pressing strips 3, and an oil groove 31 is arranged inside the sliding part-taking block pressing strip 3. The other end of the connecting rod 4 is connected to the movable wheel 5, and the movable wheel 5 is fixedly connected to the handle 6;
[0018] In this embodiment, a connecting part 51 for connecting with the connecting rod 4 is arranged on the movable wheel;
[0019] An inclined surface 21 is arranged on the base 2, and the movable wheel 5 is arranged on the inclined surface 21;
[0020] The sliding part-taking block pressing strip 3 is fixed to the base 2 by bolts;
[0021] Both ends of the connecting rod 4 are connected to the sliding part-taking block 1 and the movable wheel 5 by bolts respectively;
[0022] In the above structure, the movable wheel 5 can move (roll) within a certain range on the base 2 under the rotational force of the handle 6. During the movement of the handle 6, the connecting rod 4 is driven, and the connecting rod 4 then drives the sliding part-taking block 1. This device converts the circular motion of the movable wheel 5 into the reciprocating motion of the sliding part-taking block 1 through the connecting rod 4;
[0023] When in use, as Figure 2 shown, align the air needle hook 71 of the mold air needle 7 with the corresponding part-taking hook 11 of the sliding part-taking block 1, and rotate the handle 6 forcefully to take out the air needle from the inside of the mold.
[0024] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
