Description

Technical Field

[0001] This utility model relates to the field of medical product manufacturing, and in particular to a semi-automatic jig device and a semi-automatic jig for demolding needle products. Background Technology

[0002] Cardiac radiofrequency ablation is an interventional technique that involves inserting an electrode catheter into a specific location within the heart chamber via a vein or artery, releasing radiofrequency current to cause coagulative necrosis of the local endocardium and subendocardial myocardium, thereby blocking the abnormal conduction bundles and origin points of rapid arrhythmias.

[0003] In some existing electrode conduit pin products, the product mold relies on a die strip to form the product during the manufacturing process. After the product is formed, it adheres to the die strip. Once formed, the product is difficult to separate from the die strip, mainly due to the following reasons:

[0004] 1) Material and injection molding: The pins are made of rigid polypropylene (PP) with a shrinkage rate of 1.5-1.8%, which is a relatively hard material and therefore not easy to separate. The pins need to be cooled in the mold. During the cooling process, due to the large shrinkage rate of the material, the pins are very firmly attached to the mold strip after molding, making them difficult to separate manually.

[0005] 2) Product design: The ejection direction of the pin product is 90° with the mold strip, and no draft angle is designed, making it difficult to separate.

[0006] 3) Mold design: The pin product has eight cavities per mold on the mold strip, resulting in a large number of separations and a relatively long separation time. After the pin product cools down, the separation becomes more difficult.

[0007] To address the problem of the aforementioned products being difficult to separate from the mold strip, the inventors of this utility model provide a solution to resolve the difficulty in demolding existing pin products. Utility Model Content

[0034] like Figures 1-3 As shown, this utility model is a semi-automatic fixture device for demolding pin products, which includes a drive device 10 and a fixture body 20. The drive device 10 is connected to the fixture body 20 and can drive the fixture body 20 to demold the pin product P.

[0035] like Figure 1 As shown, the drive device 10 includes a drive switch 11, a power supply 12, a solenoid valve 13, and a transmission component 14. The power supply 12 is connected to the drive switch 11 and the solenoid valve 13. The transmission component 14 is used to connect to the fixture body 20. The drive switch 11 can electrically control the solenoid valve 13, thereby introducing energy from the solenoid valve into the transmission component 14, so that the transmission component 14 drives the fixture body 20 to operate.

[0036] Preferably, in this embodiment, the drive switch 11 is specifically a foot pedal switch, but it can also be a manual switch or other mechanical or electronic components that can be used to drive the solenoid valve. This utility model does not limit the specific components. The transmission component 14 is a pneumatic cylinder, but it can also be a hydraulic cylinder or electric cylinder that can produce a linear actuation effect. It is mainly used to drive the jig body 20 to perform demolding operations. Preferably, the transmission component 14 can be provided with an adjustment component 141 for adjustment. The adjustment component 141 can be used to adjust the output force of the transmission component 14. In this embodiment, the adjustment component 141 is a pressure gauge.

[0037] The drive device 10 of this utility model includes the examples in the embodiments, but is not limited to this type. For example, the drive switch 11 of the drive device 10 can be a manual switch or set to an automatic switch, and can be further equipped with an electric cylinder or hydraulic cylinder as required, or multiple transmission components 14 can be used according to different demolding forces. All of these are within the scope of the examples of this utility model.

[0038] like Figures 1-3As shown, the fixture body 20 includes a base 21 and a mold base fixing block 22, a transmission component fixing block 23, two mold strip stops 24, a product positioning template 25, and a movable template 26 disposed above the base 21. The mold base fixing block 22 is locked to the front side of the base 21, and the transmission component fixing block 23 is locked to the rear side of the base 21. A mold strip stop 24 is screwed onto each side of the mold base fixing block 22. The product positioning template 25 is disposed in the middle of the two mold strip stops 24 and can slide back and forth relative to the mold base fixing block 22. The movable template 26 is connected to the rear side of the product positioning template 25 and is located between the mold base fixing block 22 and the transmission component fixing block 23. The aforementioned transmission components 14 are respectively connected to the transmission component fixing block 23 on the fixed side and connected to the movable template 26 on the movable side. The transmission components 14 can drive the movable template 26 to move forward and backward, and further drive the product positioning template 25 to move forward or backward.

[0039] like Figure 3 As shown, preferably, the product positioning template 25 has a plurality of product positioning cavities 251 formed therein. Each product positioning cavity 251 is provided with a locking block 252, a first positioning groove 253 and a second positioning groove 254. The locking block 252 is a groove shape corresponding to the product, and the first positioning groove 253 and the second positioning groove 254 are boss shapes corresponding to the product. Different product positioning cavities 251 can be designed according to different product requirements. More specifically, there are eight product positioning cavities 251 in this embodiment, which are suitable for the design of pin products with eight cavities in one mold. The shape of the product positioning cavity 251 of this utility model can be applied to specific products. Based on similar technical means, it can also be applied to the demolding process of products with similar shapes. This utility model does not impose any limitations.

[0040] This invention can generate power through the drive device 10 and drive the transmission component 14 to drive the jig body 20 to move, thereby demolding the pin product P to be demolded.

[0041] like Figures 4 to 6 As shown, taking this embodiment as an example, the pin product P to be demolded is fixed on the mold strip T during the molding process. In this embodiment, the pin product is a mold with eight cavities. On the mold strip T, eight pin products P to be demolded are connected by pins T1.

[0042] In order to separate the aforementioned pin product P from the mold strip T, the existing method is to forcibly peel it off manually, which is both time-consuming and labor-intensive. Therefore, the semi-automatic fixture device of this utility model can separate the aforementioned pin product P from the mold strip T by mechanical means.

[0043] like Figures 4 to 8As shown, firstly, the pin products P are respectively positioned on the product positioning template 25 of the fixture body 20, and the positions of the pin products P are respectively locked in the locking block 252, the first positioning groove 253, and the second positioning groove 254. Then, the air pressure is introduced into the transmission component 14 through the solenoid valve 13 by the drive switch 11 of the drive device 10. When the transmission component 14 drives the movable template 26 forward, it will successively drive the product positioning template 25 to move forward relative to each other. At this time, since the two sides of the mold strip T are blocked by the two mold strip blocks 24 and remain in the original position, the product positioning template 25 with multiple pin products P moves forward, thus causing multiple pin products P to fall off from the pin T1 and separate from the mold strip T, thereby achieving the effect of demolding each pin product P from the mold strip T.

[0044] The advantage of this utility model is that it adopts a flexible combination of a drive device and a fixture body, which improves the current method of forcibly demolding by manpower. The drive device can be driven by foot pedal and electric power to drive a pneumatic cylinder, which works in conjunction with a semi-automatic fixture body, so that multiple pin products can be demolded at one time, thus improving production efficiency.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the present utility model's technical solution shall still fall within the scope of the present utility model's technical solution.
