Description

Technical Field

[0001] This utility model relates to the field of shaping devices, and in particular to a shaping device for injection molded parts. Background Technology

[0002] Injection molding involves placing granular or powdered plastic into the barrel of an injection molding machine and heating it to melt it. Then, pressure is applied using a push rod or rotating screw to inject the plastic material from the nozzle and the gating system of the mold into the mold cavity for cooling and molding.

[0003] Since injection molded parts are made from molten plastic granules, when the injection molded parts are taken out of the mold, the temperature difference will cause the injection molded parts to bend and deform during the cooling process. Therefore, after the injection molded parts are taken out, a shaping fixture is needed to squeeze and shape the injection molded parts to reduce the deformation that occurs when the injection molded parts cool down.

[0004] However, when the molding fixture compresses and binds the injection molded part, multiple molding fixtures are usually mounted on a support plate using fixed seats and fixing bolts to ensure the stability of the molding fixture during operation. Furthermore, the support plate is usually made of iron and has a fixed number of threaded holes for mounting bolts, which makes it inconvenient to adjust the position of adjacent molding fixtures on the support plate according to the shape of the injection molded part, thus presenting certain defects.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides, for example Figure 1-3 The image shows a shaping device for injection molded parts.

[0038] Example 1

[0039] The assembly includes a support plate 1, a shaping fixture 2, a connecting rail 3, a connecting seat 4, and a locking assembly 5. The shaping fixture 2 is located on top of the support plate 1 and is used for extruding and shaping the injection molded part. Figure 1As shown, the shaping fixture 2 consists of a mounting component, a handle, a connector, a pin, and an extrusion block. Rotating the handle drives the connector to rotate, thereby causing the extrusion block to move and extrude the injection molded part. This is a mature existing technology and will not be described in detail here. The connecting rail 3 is fixedly installed on the top of the support plate 1, and the connecting seat 4 is fixedly installed on the bottom of the shaping fixture 2. The connecting seat 4 is slidably engaged with the outside of the connecting rail 3. The connecting seat 4 slides on the connecting rail 3, which allows the shaping fixture 2 to move on the support plate 1, thereby changing the distance between adjacent shaping fixtures 2. The locking component 5 is set on the connecting rail 3. The locking component 5 is used to brake and lock the connecting seat 4. The locking component 5 can ensure the stability of the connecting seat 4 and the shaping fixture 2 when they are stationary.

[0040] Furthermore, the locking assembly 5 includes a brake plate 51, a rubber plate 52, and a protrusion 53. The top of the connecting rail 3 has a mounting groove 54 that matches the brake plate 51. The rubber plate 52 is fixedly connected to the top of the brake plate 51, and the protrusion 53 is fixedly connected to the top of the inner wall of the connecting seat 4. The outer wall of the protrusion 53 is pressed against the rubber plate 52, so that the rubber plate 52 on the top of the brake plate 51 is pressed against the protrusion 53, which can brake and limit the connecting seat 4 on the connecting rail 3. The locking assembly 5 also includes a mounting shaft 56 and an eccentric cam 55. The end of the outer wall of the mounting shaft 56 is slidably inserted into the connecting rail 3. The eccentric cam 55 is slidably engaged with the outside of the mounting shaft 56. The bottom of the brake plate 51 has a groove corresponding to the eccentric cam 55. The mounting shaft 56 drives the eccentric cam 55 to rotate, so that the long shaft side of the eccentric cam 55 is engaged in the groove. This allows multiple eccentric cams 55 to press the brake plate 51 toward the connecting seat 4, thus braking the connecting seat 4.

[0041] Furthermore, the locking assembly 5 also includes a slider 58 and a groove 59. The slider 58 is fixedly connected to the inside of the eccentric cam 55, and the groove 59 is opened on the outside of the mounting shaft 56. The outside of the slider 58 is slidably engaged with the inside of the groove 59. Under the action of the slider 58, the eccentric cam 55 and the mounting shaft 56 rotate synchronously. The locking assembly 5 also includes a limiting plate 510 and a handle 57. The limiting plate 510 is fixedly installed inside the mounting groove 54. One side of the limiting plate 510 has a through hole that matches the mounting shaft 56. The limiting plate 510 is located on the side of the eccentric cam 55. The limiting plate 510 can ensure the stability of the eccentric cam 55 when mounted on the mounting shaft 56. The handle 57 is fixedly installed at the end of the mounting shaft 56. The handle 57 can drive the mounting shaft 56 to rotate.

[0042] Example 2

[0043] Based on embodiment 1, the locking assembly 5 further includes a connecting groove 512, a connecting block 513, a fixing rod 514, and a limiting spring 515. The connecting groove 512 is opened on the side of the inner wall of the mounting groove 54. The connecting block 513 is fixedly connected to the side of the brake plate 51. One end of the fixing rod 514 is fixedly connected to the top of the inner wall of the connecting groove 512. The outer wall of the fixing rod 514 is slidably inserted and sleeved with the connecting block 513. The limiting spring 515 is slidably sleeved on the outside of the fixing rod 514. The limiting spring 515 is located on the top of the connecting block 513. The limiting spring 515 can give the brake plate 51 a spring force that moves towards the inside of the mounting groove 54 through the connecting block 513. That is, it separates from the brake plate 51 on the long axis side of the eccentric cam 55, so that the brake plate 51 can drive the rubber plate 52 to separate from the protrusion 53, thereby allowing the connecting seat 4 to slide outside the connecting track 3.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
