A sleeve assembly tool

Abstract

This utility model proposes a sleeve assembly fixture, including a base plate, a first slide rail on the base plate, a second slide rail on the first slide rail, and a sliding seat on the second slide rail. A pull rod is fixedly connected to the bottom surface of the sliding seat. The advantages of this utility model are: the driven shaft drives the drive plate to move vertically, and the movement of the drive plate can compress the driven plate, thereby driving the clamping rod and clamping plate to move. The sleeve is placed in the clamping frame. Reversing the drive shaft causes the drive plate to gradually move away from the driven plate, and under the action of a spring, the clamping plate moves to clamp the sleeve. Subsequently, the mold is clamped using a mold clamping assembly, and the first slide rail, second slide rail, and sliding seat drive the sleeve to move, assembling the sleeve. The operator can rotate the drive shaft to drive multiple drive plates to move synchronously, thereby driving multiple clamping plates to move synchronously. The operation is simpler, and the fixed position is centered, which helps improve assembly accuracy.

Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a sleeve assembly tooling. Background Technology

[0002] Ejector sleeves are commonly used mold components in the mold manufacturing industry, especially in injection molds. They mainly consist of an ejector sleeve and ejector pins, which work together to eject the product during mold opening, ensuring the product can be smoothly removed from the mold and preventing it from sticking or being damaged.

[0003] When the ejector sleeve is installed on a plastic mold, it is usually assembled in parallel due to the mold design. However, existing assembly methods typically involve direct installation after measurement, resulting in low precision and susceptibility to errors. An existing ejector sleeve assembly fixture uses two sets of clamping components to hold the ejector sleeve and the mold separately, and then adjusts the position of the ejector sleeve to achieve precise installation. However, this fixture uses multiple sets of springs in conjunction with support rods and clamping plates to clamp the ejector sleeve. During clamping, the positions of multiple clamping plates need to be adjusted sequentially, which is inconvenient and can lead to the ejector sleeve being misaligned with the center of the clamping components, affecting assembly accuracy. Therefore, an improved ejector sleeve assembly fixture is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a sleeve assembly tool to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a sleeve assembly fixture, including a base plate, a first slide rail on the base plate, a second slide rail on the first slide rail, a sliding seat on the second slide rail, a pull rod fixedly connected to the bottom surface of the sliding seat, a clamping frame fixedly connected to the bottom end of the pull rod, a plurality of clamping rods inserted into the side of the clamping frame, a clamping plate fixedly connected to the inner end of each clamping rod, a spring provided between the clamping plate and the clamping frame, and a driven plate fixedly connected to the outer end of each clamping rod; a transmission box is provided on the clamping frame, a drive shaft is rotatably connected inside the transmission box, and a driven shaft rotatably connected inside the transmission box that can rotate with the drive shaft, a drive plate threadedly connected to the driven shaft, and the drive plate, when driven by the driven shaft, can move the driven plate away from the clamping frame. A lockable turntable is provided at the outer end of the drive shaft; a mold clamping assembly for fixing a mold is provided on the base plate.

[0007] Preferably, any of the above solutions includes a locking component on the sliding seat that can be fixed to the second slide rail, and there are several sliding seats.

[0008] The above technical solution provides an installation platform for the first slide rail, mold clamping components, and other structures. The cooperation of the first and second slide rails allows for the displacement of the sliding seat in different directions, facilitating adjustments to its specific position by operators as needed. A locking component is installed on the sliding seat to lock it in place when necessary, preventing displacement.

[0009] Preferably, in any of the above solutions, the clamping frame adopts a rectangular structure, and each clamping frame has two clamping rods on its side.

[0010] The above technical solution employs a clamping frame that provides clamping space for the ejector sleeve. The clamping frame has a rectangular structure, facilitating the installation of the upper structure. The clamping rods provide support for the clamping plates and can move the clamping plates horizontally under external force. Two clamping rods are installed on the side of the clamping frame, allowing the ejector sleeve to be clamped from both sides by two sets of clamping rods and clamping plates, ensuring its stability.

[0011] Preferably, in any of the above embodiments, the inner side of the clamping plate is arc-shaped, an anti-slip pad is provided on the inner side of the clamping plate, and the spring is sleeved on the outer side of the clamping rod.

[0012] The above technical solution employs a clamping plate that holds the sleeve, with an arc-shaped inner surface for better gripping. An anti-slip pad is placed on the inner side of the clamping plate to further improve clamping stability. A spring provides elastic support to the clamping plate, allowing it to move horizontally under external force. The spring is sleeved on the outside of the clamping rod to prevent displacement of the clamping rod in other directions.

[0013] Preferably, in any of the above embodiments, bevel gears that mesh with each other are provided on the drive shaft and the driven shaft, and the transmission box is located in the middle of the clamping frame.

[0014] The above technical solution involves rotating the drive shaft, which in turn drives the driven shaft to rotate. Under the constraint of the transmission box, the driven shaft causes the drive plate to move vertically. The movement of the drive plate can compress the driven plate, thereby causing the clamping rod and clamping plate to move. By using bevel gears for transmission between the drive shaft and the driven shaft, the operator can rotate the drive shaft to drive multiple drive plates to move synchronously, which in turn can drive multiple clamping plates to move synchronously.

[0015] Preferably, in any of the above solutions, a limiting groove is formed on the inner wall of the transmission box, and a limiting block disposed in the limiting groove is fixedly connected to the side of the drive plate.

[0016] The above technical solution involves creating a limiting groove on the inner wall of the transmission box, which, in conjunction with a limiting block on the drive plate, allows the limiting block to move within the limiting groove, preventing the drive plate from completely detaching from the transmission box.

[0017] Preferably, the transmission box has several circumferentially evenly arranged lock holes, and the turntable is threaded with a locking pin that can be inserted into the lock holes.

[0018] The above technical solution involves a lockable turntable at the outer end of the drive shaft, facilitating operator control. The turntable is lockable, preventing accidental movement of the clamping components. A locking pin and locking hole are used to lock the turntable, resulting in a simple structure and convenient operation.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] 1. This sleeve assembly fixture, through the arrangement of a clamping frame, clamping rod, clamping plate, driven plate, drive shaft, transmission box, and other structures, allows for sleeve assembly. Rotating the turntable drives the drive shaft, which in turn drives the driven shaft. Under the constraint of the transmission box, the driven shaft causes the drive plate to move vertically. The movement of the drive plate compresses the driven plate, which in turn moves the clamping rod and clamping plate, placing the sleeve within the clamping frame. Reversing the drive shaft causes the drive plate to gradually move away from the driven plate, and under the action of a spring, the clamping plate moves to clamp the sleeve. Subsequently, the mold clamping assembly clamps the mold, and the first slide rail, second slide rail, and sliding seat drive the sleeve to move, assembling the sleeve. Operators can rotate the drive shaft to move multiple drive plates synchronously, which in turn moves multiple clamping plates synchronously. This simplifies operation and ensures a centered fixed position, improving assembly accuracy.

[0021] 2. This sleeve assembly fixture features a locking component on the sliding seat to easily lock it when needed, preventing displacement. An anti-slip pad is placed on the inner side of the clamping plate to further improve clamping stability. A spring is fitted onto the outer side of the clamping rod to prevent displacement in other directions. A limiting groove is formed on the inner wall of the transmission box, which, in conjunction with a limiting block on the drive plate, allows the limiting block to move within the limiting groove, preventing the drive plate from completely detaching from the transmission box.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1-4 As shown, this utility model includes a base plate 1, a first slide rail 2 on the base plate 1, a second slide rail 3 on the first slide rail 2, a sliding seat 4 on the second slide rail 3, a pull rod 5 fixedly connected to the bottom surface of the sliding seat 4, a clamping frame 6 fixedly connected to the bottom end of the pull rod 5, several clamping rods 7 inserted into the side of the clamping frame 6, a clamping plate 8 fixedly connected to the inner end of the clamping rod 7, a spring 15 between the clamping plate 8 and the clamping frame 6, and a driven plate 9 fixedly connected to the outer end of the clamping rod 7; a transmission box 10 is provided on the clamping frame 6, a drive shaft 11 is rotatably connected inside the transmission box 10, a driven shaft 12 rotatably connected inside the transmission box 10 that can rotate with the drive shaft 11, a drive plate 13 is threadedly connected to the driven shaft 12, and the drive plate 13 can drive the driven plate 9 to move away from the clamping frame 6 when driven by the driven shaft 12. The outer end of the drive shaft 11 is provided with a lockable turntable 14; the base plate 1 is provided with a mold clamping assembly 16 that can fix the mold.

[0032] Example 1: A locking assembly is provided on the sliding seat 4 to fix it to the second slide rail 3. There are several sliding seats 4. The base plate 1 provides an installation platform for the first slide rail 2, the mold clamping assembly 16, and other structures. The first slide rail 2 and the second slide rail 3 cooperate to provide conditions for the displacement of the sliding seat 4 in different directions, making it convenient for the staff to adjust the specific position of the sliding seat 4 according to actual needs. The locking assembly is provided on the sliding seat 4 to lock the sliding seat 4 when needed, preventing the sliding seat 4 from shifting. The clamping frame 6 adopts a rectangular structure, and two clamping rods 7 are provided on the side of each clamping frame 6. The clamping frame 6 provides clamping space for the ejector sleeve. The rectangular structure of the clamping frame 6 facilitates the installation of the structure on it. The clamping rods 7 provide support for the clamping plate 8 and can drive the clamping plate 8 to move horizontally under external force. The two clamping rods 7 on the side of the clamping frame 6 allow the ejector sleeve to be clamped from both sides by two sets of clamping rods 7 and clamping plates 8, ensuring its stability.

[0033] Example 2: The inner surface of the clamping plate 8 is curved, and an anti-slip pad is provided on the inner side of the clamping plate 8. The spring 15 is sleeved on the outer side of the clamping rod 7. The clamping plate 8 clamps the sleeve, and its inner surface is curved to better clamp the sleeve. The anti-slip pad on the inner side of the clamping plate 8 helps to further improve the stability of the clamping. The spring 15 provides elastic support for the clamping plate 8, allowing it to move horizontally under the action of external force. Sleeving the spring 15 on the outer side of the clamping rod 7 can prevent the clamping rod 7 from displacing in other directions. The drive shaft 11 and the driven shaft 12 are provided with meshing bevel gears, and the transmission box 10 is located in the middle of the clamping frame 6. Rotating the drive shaft 11 drives the driven shaft 12 to rotate. Under the constraint of the transmission box 10, the driven shaft 12 drives the drive plate 13 to move vertically. The movement of the drive plate 13 can squeeze the driven plate 9, thereby driving the clamping rod 7 and the clamping plate 8 to move. By using bevel gears to transmit power between the drive shaft 11 and the driven shaft 12, the operator can drive multiple drive plates 13 to move synchronously by rotating the drive shaft 11, which in turn can drive multiple clamping plates 8 to move synchronously.

[0034] Example 3: A limiting groove is formed on the inner wall of the transmission box 10, and a limiting block is fixedly connected to the side of the drive plate 13, which is set in the limiting groove. The limiting groove on the inner wall of the transmission box 10, in conjunction with the limiting block on the drive plate 13, allows the limiting block to move within the limiting groove, preventing the drive plate 13 from completely detaching from the transmission box 10. The transmission box 10 has several evenly arranged circumferential locking holes, and a locking pin threaded onto the turntable 14 can be inserted into the locking holes. A lockable turntable 14 is provided at the outer end of the drive shaft 11, facilitating operation of the drive shaft 11 by the operator. The turntable 14 can be locked to prevent accidental movement of the clamping components. The turntable 14 is locked using a locking pin and locking holes, resulting in a simple structure and convenient operation.

[0035] The working principle of this utility model is as follows:

[0036] S1. Rotating turntable 14 drives drive shaft 11 to rotate, drive shaft 11 drives driven shaft 12 to rotate. Under the constraint of transmission box 10, driven shaft 12 drives drive plate 13 to make vertical displacement. The movement of drive plate 13 can squeeze driven plate 9, thereby driving clamping rod 7 and clamping plate 8 to move.

[0037] S2. Place the sleeve inside the clamping frame 6. Rotate the drive shaft 11 in the opposite direction, and the drive plate 13 gradually moves away from the driven plate 9. Under the action of the spring 15, the clamping plate 8 moves to clamp the sleeve.

[0038] S3. The mold is clamped by the mold clamping assembly 16, and the first slide rail 2, the second slide rail 3, and the sliding seat 4 are used to move the ejector sleeve to assemble the ejector sleeve.

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] 1. This sleeve assembly fixture, through the arrangement of a clamping frame 6, clamping rod 7, clamping plate 8, driven plate 9, drive shaft 11, transmission box 10, driven shaft 12, and drive plate 13, etc., allows for sleeve assembly. Rotating the turntable 14 drives the drive shaft 11 to rotate, which in turn drives the driven shaft 12. Under the constraint of the transmission box 10, the driven shaft 12 drives the drive plate 13 to move vertically. The movement of the drive plate 13 can compress the driven plate 9, thereby moving the clamping rod 7 and clamping plate 8. The sleeve is placed within the clamping frame 6. Reversing the rotation of the drive shaft 11 causes the drive plate 13 to gradually move away from the driven plate 9. Under the action of the spring 15, the clamping plate 8 moves to clamp the sleeve. Subsequently, the mold is clamped using the mold clamping assembly 16, and the sleeve is moved using the first slide rail 2, the second slide rail 3, and the sliding seat 4 to assemble the sleeve. The operator can rotate the drive shaft 11 to move multiple drive plates 13 synchronously, which in turn moves multiple clamping plates 8 synchronously. The operation is simpler, and the fixed position is centered, which helps to improve assembly accuracy.

[0041] 2. This sleeve assembly fixture features a locking component on the sliding seat 4, allowing for easy locking of the sliding seat 4 when needed to prevent displacement. An anti-slip pad is provided on the inner side of the clamping plate 8 to further improve clamping stability. A spring 15 is fitted onto the outer side of the clamping rod 7 to prevent displacement of the clamping rod 7 in other directions. A limiting groove is formed on the inner wall of the transmission box 10, which, in conjunction with a limiting block on the drive plate 13, allows the limiting block to move within the limiting groove, preventing the drive plate 13 from completely detaching from the transmission box 10.
