Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to an assembly auxiliary device for manufacturing injection molds. Background Art

[0002] Assembly aids for plastic mold manufacturing are a series of tools or equipment used to assist mold assembly during the injection mold manufacturing process. The following are some common assembly aids for injection mold manufacturing and their functions. Positioning fixtures: used to ensure that mold parts can be accurately aligned during assembly to ensure the accuracy and fit of the mold.

[0003] However, common positioning fixtures often have certain limitations. For example, in many cases, they can only achieve the positioning, clamping and fixing of mold parts, but do not have the function of flipping after fixing. This leads to the fact that in actual assembly work, when the other side of the mold needs to be assembled, it is often impossible to directly flip the already fixed mold over conveniently, making the operation process more cumbersome and complicated. The assembler may need to loosen the fixed mold first, then flip it, and then re-fix and align it, which not only increases the operation steps and time cost, but also easily introduces errors and uncertainties during repeated operations, affecting the efficiency and quality of assembly. Therefore, an assembly auxiliary device for injection mold manufacturing is proposed herein. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 An assembly auxiliary device for manufacturing injection molds, including a fixed frame 1 and a rotating frame 2, a screw rod 3 is rotatably provided on the rotating frame 2, a through frame 4 is threadedly sleeved on the screw 3, a movable groove is provided on the through frame 4, a movable rod 5 is provided in the movable groove through a buffer mechanism, a positioning plate 6 is installed on the movable rod 5, a slide groove is provided on the fixed frame 1, a slide rod 13 is provided in the slide groove, a slide sleeve 14 is slidably sleeved on the slide rod 13 through a reset mechanism, a movable frame 8 is installed on the slide sleeve 14, a rotating shaft 7 is rotatably provided on the fixed frame 1 and the movable frame 8, a power mechanism connected to the rotating shaft 7 is provided on the fixed frame 1, and the rotating frame 2 is connected to the two rotating shafts 7 through a clamping mechanism.

[0022] The buffer mechanism includes a buffer spring 11 installed in the movable groove. The two ends of the buffer spring 11 are elastically connected to the outer wall of the movable rod 5 and the inner wall of the movable groove respectively. During the extrusion process, the buffer spring 11 can absorb and mitigate the impact force generated when the positioning plate 6 contacts the mold at the moment, avoiding damage to the mold and the positioning plate 6 caused by rigid collision, and playing a protective role.

[0023] The reset mechanism includes a reset spring 15 sleeved on the outside of the slide rod 13, and the two ends of the reset spring 15 are elastically connected to the outer wall of the slide sleeve 14 and the inner wall of the slide groove respectively. The elastic potential energy provided by the reset spring 15 can realize the automatic movement and reset operation of the movable frame 8 after the movable frame 8 moves relative to the fixed frame 1 and loses the drag force.

[0024] The power mechanism includes a driving motor mounted on the fixing frame 1 , the output shaft of the driving motor rotates through the fixing frame 1 and is fixedly connected to the rotating shaft 7 , and after the driving motor is started, it can directly drive the rotating shaft 7 connected thereto to rotate.

[0025] The clamping mechanism includes a clamping shaft installed on the rotating frame 2. The rotating shaft 7 is provided with a clamping groove 12 corresponding to the clamping shaft. As shown in the figure, the clamping groove 12 is in the shape of a regular hexagon. Then, the clamping shaft is connected with the corresponding setting to complete the clamping.

[0026] A plurality of stabilizing plates 10 are provided on the fixed frame 1, and a handle 9 is installed on the movable frame 8. With the aid of the stabilizing plates 10, the overall stable support of the device is achieved, and the handle 9 can be used to conveniently drag and move the movable frame 8.

[0027] A protective pad is provided on the positioning plate 6. The protective pad is made of rubber and has anti-skid patterns on the surface. The anti-skid patterns can significantly increase the friction between the protective pad and the mold, making the mold more stable when being squeezed and fixed, and not easy to slide or shift, ensuring that the mold can maintain a fixed position during operation. The rubber material is relatively soft, which can prevent the positioning plate 6 from directly contacting the mold and causing scratches or damage to the mold surface, thereby protecting the mold.

[0028] When the utility model is used, the mold is in the rotating frame 2, and a rotating block is installed on the screw 3 to facilitate rotation. After the screw 3 is rotated, the movable frame 8 threadedly installed thereon will move, and cooperate with the movable rod 5 to drive the contact mold, and rely on the protection provided by the buffer spring 11 and the protective pad to reduce the extrusion damage to the mold. At this time, after the mold is squeezed and fixed, other components can be installed on the upward side. After the side is installed, the drive motor is started. The drive motor can drive the rotating frame 2 to rotate with the help of the rotating shaft 7. The rotating frame 2 rotates 180 degrees to complete the flip, and other components can be installed on the other side of the mold.

[0029] In this solution, the handle 9 can be grasped to drag the movable frame 8, and the movable frame 8 is connected to the sliding sleeve 14 and moves on the sliding rod 13, and then the rotating shaft 7 on the movable frame 8 is disengaged from one of the clamping shafts on the rotating frame 2, and then the rotating frame 2 is released and can be disassembled, so that the rotating frame 2 and the positioning plate 6 and other components can be inspected, cleaned, maintained or specially treated separately. When it is necessary to switch to a mold of a different model or specification, the current rotating frame 2 and the positioning plate 6 can be quickly disassembled and replaced with a new combination to achieve efficient production conversion.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
