Description

Technical Field

[0001] This utility model relates to the field of demolding technology, and in particular to a structure for removing external threads by pushing the ejector sleeve. Background Technology

[0002] Demolding refers to the important step of removing the molded product from the mold, allowing the mold to complete its processing.

[0003] After the threaded product is manufactured, the general demolding method is to forcibly move the outer forming mold to gradually expose the inner product. However, when removing the forming mold, the direction of movement is generally perpendicular to the thread direction, which can easily affect the threads on the formed product. In addition, multiple molds are usually moved one by one, which affects the demolding efficiency and the production effect.

[0004] Therefore, we provide a sleeve push position unscrewed external thread structure. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a sleeve-pushing position unscrewing structure, thereby achieving efficient and safe demolding.

[0006] In view of this, the present invention provides a sleeve pusher mechanism for removing external threads, including a sleeve pin, an outer sleeve, a sliding seat, and a movable sliding position. The sleeve pin is inserted into the interior of the outer sleeve and extends above the outer sleeve. The outer sleeve is inserted into the interior of the sliding seat. There are at least four movable sliding positions, and the four movable sliding positions are inserted into the sliding seat. Each movable sliding position has a molding die at its upper end. An insertion block is injection molded between the four molding dies. The outer sleeve contacts the inner side of the movable sliding position through an outer pusher. The insertion block is located directly above the sleeve pin.

[0007] Preferably, the upper end of the outer sleeve is provided with an outer push cylinder, the outer push cylinder is conical, and the lower half of the inner side of the moving position is a conical slope with the same specifications as the outer push cylinder.

[0008] Preferably, an outer pin is installed at the upper end of the outer push cylinder. The outer pin is cylindrical with a diameter smaller than that of the outer push cylinder, and the specifications of the outer pin are consistent with the smaller surface of the outer push cylinder. The outer pin is in contact with the upper half of the inner side of the moving position.

[0009] Preferably, the outer push cylinder, the outer insert pin, and the outer sleeve are internally connected, and an insert pin is inserted into the outer insert pin, a push cone is inserted into the outer push cylinder, and the sleeve pin is inserted into the outer sleeve.

[0010] Preferably, the push cone is installed on the upper end of the ejector pin, and the push cone has a conical structure. The specifications of the push cone are larger than those of the outer push cylinder, and the specifications of the insertion pin are smaller than those of the outer insertion pin and the outer push cylinder.

[0011] Preferably, the upper end of the connector pin is equipped with an ejector pin, the ejector pin is inserted into the inside of the connector block, and the lower end surface of the connector block is in contact with the upper end surface of the connector pin.

[0012] Preferably, a limiting groove is provided on the row seat, the limiting groove is inserted into the moving row, and limiting blocks are provided on both sides of the moving row, the limiting blocks being located inside the upper half of the limiting groove.

[0013] Preferably, the upper end of the movable slide is provided with an insertion groove, a positioning block is inserted into the insertion groove, the positioning block is inserted with an insertion block, and the insertion block is installed at the lower end of the forming mold.

[0014] Compared with the prior art, this utility model provides a sleeve push position unscrewing structure, which has the following beneficial effects:

[0015] 1. This utility model, by pushing the ejector pin, can drive the external ejector, the moving slide, and the forming mold to move synchronously, and make them move synchronously in the horizontal direction of the thread, thereby improving the safety of the product during demolding.

[0016] 2. In this utility model, after the moving slide and the forming mold are pushed to the side a certain distance, the insert block is disengaged from the threaded mold on the side of the forming mold, so that it can be pushed out by the ejector pin, thereby achieving the effect of pushing and demolding, ensuring the stability and safety of the insert block after forming.

[0017] 3. This utility model, by changing the demolding method to the simultaneous horizontal outward movement of multiple molding support molds, can improve the demolding efficiency of the product while ensuring the safety of the product in the middle of the molding process, and effectively prevent the demolding loss caused by the existing single demolding method for products with certain limitations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: A structure for removing external threads during the push-out position of the ejector sleeve, such as... Figure 1 - Figure 5 As shown, it includes a ejector pin 1, an outer ejector sleeve 2, a sliding seat 3, and a movable sliding seat 4. The ejector pin 1 is inserted into the outer ejector sleeve 2 and extends above the outer ejector sleeve 2. The outer ejector sleeve 2 is inserted into the sliding seat 3. There are at least four movable sliding seats 4, and the four movable sliding seats 4 are inserted into the sliding seat 3. Each movable sliding seat 4 has a molding mold 5 at its upper end. An insertion block 6 is injection molded between the four molding molds 5. The outer ejector sleeve 2 contacts the inner side of the movable sliding seat 4 through the outer push tube 201. The insertion block 6 is located directly above the ejector pin 1.

[0028] After the outer limiting mold is removed, with the slide seat 3 fixed, push the ejector pin 1, causing it to move the outer ejector pin 2 synchronously, moving it into the slide seat 3. Based on the limiting contact of the outer pusher 201, the same moving slide 4 moves outward, causing the forming mold 5 above it to move outward synchronously, exposing the insertion block 6 in the middle. With the continuous pushing of the ejector pin 1, the outer ejector pin 2 pushes the peripheral moving slide 4 to move outward continuously, gradually increasing the distance between the moving slide 4 and the forming mold 5. Supported by the ejector pin 1, the insertion block 6 is pushed outward. As block 6 continues to move upward, it pushes the insert block 6 out of the middle of multiple forming molds 5, thereby achieving the effect of pushing the insert block 6 out. By pushing the ejector pin 1, the external ejector pin 2, the moving slide 4, and the forming mold 5 can be driven to move synchronously in the horizontal direction of the thread, improving the safety of the product during demolding. After the moving slide 4 and the forming mold 5 are pushed to the side a certain distance, the insert block 6 is separated from the threaded mold on the side of the forming mold 5, so that it can be pushed out by the ejector pin 1, achieving the effect of pushing demolding and ensuring the stability and safety of the insert block 6 after molding.

[0029] like Figure 1 - Figure 5 As shown, an outer push cylinder 201 is provided at the upper end of the outer sleeve 2. The outer push cylinder 201 is conical, and the lower half of the inner side of the moving position 4 is a conical inclined surface with the same specifications as the outer push cylinder 201.

[0030] An outer pin 202 is installed on the upper end of the outer push cylinder 201. The outer pin 202 is cylindrical with a diameter smaller than that of the outer sleeve 2. The specifications of the outer pin 202 are consistent with the smaller surface of the outer push cylinder 201. The outer pin 202 is in contact with the upper half of the inner side of the moving position 4.

[0031] When the outer sleeve 2 moves into the slide seat 3, the outer pin 202 first inserts into the upper half of the moving slide 4, and the outer pusher 201 on it gradually contacts the moving slide 4. Under the limitation of the lower half of the inclined surface of the inner side of the moving slide 4, the moving slide 4 as a whole is subjected to the outward pushing force, so that the moving slide 4 and the forming mold 5 gradually move outward. The movement can only stop when the internal space of the moving slide 4 is slightly larger than the overall size of the outer sleeve 2. Thus, the pushing of the outer sleeve 2 can automatically control the moving distance of the moving slide 4, ensuring the accuracy and stability of the demolding distance pushed by the device.

[0032] like Figure 1 - Figure 5 As shown, the outer push cylinder 201, the outer insert pin 202, and the outer sleeve 2 are internally connected, and the outer insert pin 202 has an insert pin 102 inserted inside, the outer push cylinder 201 has a push cone 101 inserted inside, and the sleeve pin 1 is inserted into the outer sleeve 2.

[0033] The push cone 101 is installed on the upper end of the sleeve needle 1, and the push cone 101 has a conical structure. The specifications of the push cone 101 are larger than those of the outer push cylinder 201, and the specifications of the insertion needle 102 are smaller than those of the outer insertion needle 202 and the outer push cylinder 201.

[0034] A push pin 103 is installed on the upper end of the plug pin 102. The push pin 103 is inserted into the plug block 6, and the lower surface of the plug block 6 is in contact with the upper surface of the plug pin 102.

[0035] When the ejector pin 1 is moved, its upper insertion pin 102 first inserts into the outer insertion pin 202 through the outer ejector pin 2. Based on the limiting effect of the inner wall of the outer push cylinder 201 on the outer side of the push cone 101, the push cone 101, after contacting the outer push cylinder 201, pushes the ejector pin 1 and the push cone 101, thereby driving the outer push cylinder 201 to be pushed simultaneously, thus pushing the entire outer ejector pin 2, ensuring the stability and accuracy of pushing its alignment components. At the same time, the ejector pin 103 gradually moves towards the middle of the insertion block 6. Under the limiting contact of the insertion pin 102, the multiple molding molds 5 of the side molding support are disengaged from the limiting distance, so that the ejector pin 103 and the insertion pin 102 can contact the insertion block 6 simultaneously and push it upward, achieving the effect of pushing demolding.

[0036] Example 2: A sleeve-pushing mechanism for removing external threads, such as... Figure 1 - Figure 5 As shown, a limiting groove 301 is provided on the row seat 3. The limiting groove 301 is inserted into the moving row 4, and limiting blocks 8 are provided on both sides of the moving row 4. The limiting blocks 8 are located inside the upper half of the limiting groove 301.

[0037] Firstly, under the guidance and limitation of the limiting groove 301, the moving slide 4 can move accurately to the outside after being pushed. Secondly, under the limitation of the limiting block 8 in the upper part of the limiting groove 301, the moving slide 4 can be effectively prevented from moving upward after being pushed, thus further ensuring the stability and accuracy of the moving slide 4 moving to the side.

[0038] like Figure 1 - Figure 5 As shown, the upper end of the moving position 4 is provided with an insertion groove 401, a positioning block 7 is inserted into the insertion groove 401, and an insertion block 6 is inserted into the positioning block 7. The insertion block 6 is installed at the lower end of the forming mold 5.

[0039] With the positioning block 7 and the insertion block 6 in a positioning connection, the forming mold 5 is positioned accurately and synchronously, ensuring its stability during forming support. By disassembling the positioning block 7, it is easy to replace the forming mold 5 with different specifications, so that the device can support multiple specifications and improve its applicability.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
