Description

Technical Field

[0001] This utility model relates to the field of mold opening self-locking structure for controlling the movement of a mold. Background Technology

[0002] Existing as Figure 7 The injection molded product shown has a shaft hole 13 at its lower part and groove structures 11 at both ends of its upper part. Small holes 12 are formed on the two opposite inner walls of each groove structure 11. When molding the small holes 12 of the groove structure 11, insert pins need to be placed on the corresponding sliding mechanism. However, because the insert pins need to completely penetrate the injection molded product, the pin heads extend into the groove structure 11. The pin heads will embed into another adjacent sliding mechanism, causing the two sliding mechanisms to interlock and interfere with each other during mold opening. Therefore, it is necessary to control the mold opening sequence to ensure that the sliding mechanism with the insert pins opens first to prevent mold collision.

[0003] Therefore, the purpose of this utility model is to provide a mold opening self-locking structure for controlling the mold slide position, so as to realize the sequential opening of two adjacent slide mechanisms. Utility Model Content

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0031] It should be noted that, in this utility model, unless otherwise stated, when an element is referred to as "connected to" or "set on" another element, it can be directly on the other element or may have an intervening element present simultaneously. The directional terms used, such as "upper" and "lower," generally refer to... Figure 1 The terms "up" and "down" are shown. "Inner" and "outer" refer to the inner and outer parts of a specific outline. "Far" and "near" refer to the distance or proximity relative to a particular component.

[0032] like Figures 1-6 As shown in the figure, an embodiment of the present invention provides a mold opening self-locking structure for controlling the movement of a mold slide, comprising:

[0033] The moving mold core has a mold core cavity in the middle;

[0034] First row position mechanism;

[0035] The second sliding mechanism, the first sliding mechanism and the second sliding mechanism are both evenly spaced around the mold core cavity, and the first sliding mechanism and the second sliding mechanism are staggered;

[0036] like Figure 4 As shown, the first row mechanism includes a first row seat 1 (3), two insert pins 5 and two self-locking inserts 6. The two insert pins 5 pass through the two ends of the surface of the first row seat 1 (3) near the mold cavity, and the two self-locking inserts 6 are respectively disposed at the two ends of the upper surface of the first row seat 1 (3).

[0037] like Figures 5-6 As shown, the second sliding mechanism includes a second sliding seat 2 (4) and a insert 7. The upper surface of the second sliding seat 2 (4) is provided with self-locking grooves 10 at both ends. The insert 7 passes through the lower end of the surface of the second sliding seat 2 (4) near the mold cavity. The upper surface of the second sliding seat 2 (4) near the mold cavity is provided with a second sliding core 8. The second sliding core 8 is provided with through holes 9 at both ends.

[0038] During mold closing, the end of the insert pin 5 away from the first row seat 1 (3) is positioned inside the through hole 9, and the end of the self-locking insert 6 away from the first row seat 1 (3) is positioned inside the self-locking groove 10. The self-locking insert 6 ensures that the second row seat 2 (4) does not move backward when the first row seat 1 (3) opens during mold opening. After the first row seat 1 (3) completes its mold opening action, the self-locking insert 6 completely disengages from the self-locking groove 10, and the second row seat 2 (4) unlocks and begins mold opening.

[0039] The first row seat 1 (3) has positioning grooves at both ends on its upper surface. One end of the self-locking insert 6 is detachably installed inside the positioning groove. The positioning groove is in the shape of an inverted L. The self-locking insert 6 is an L-shaped block. When the mold is closed, the self-locking insert 6 is embedded in the upper surface of the first row seat 1 (3) to prevent the self-locking insert 6 from protruding and causing a groove to be opened on the fixed mold core.

[0040] The extension direction of the self-locking groove 10 is parallel to the mold opening direction of the first row seat 1 (3). This ensures that the self-locking insert 6 can open and close smoothly.

[0041] The centerline of the insert 5 is parallel to the mold opening direction of the first row seat 1 (3). This ensures that the insert 5 can open and close smoothly.

[0042] The insert 7 includes a column body and a column head, which are connected sequentially along the direction away from the mold cavity. The diameter of the column body increases in a stepped manner along the direction away from the mold cavity. The column body has a stepped structure, with the end with the smaller diameter forming the product, and the stepped groove can position the product.

[0043] The column head is cylindrical and is keyed to the second row seat 2 (4). The circumferential surface of the column head is integrally formed with a protrusion for keying.

[0044] The first row mechanism further includes a guide post for driving the first row seat 1 (3) to open the mold, and the second row mechanism further includes a second driving element for driving the second row seat 2 (4) to open the mold, wherein the guide post is inclined.

[0045] The second driving element is a hydraulic cylinder. The second row seat 2 (4) is provided with a T-slot at one end away from the mold cavity. One end of the piston rod of the hydraulic cylinder is detachably provided with a pull rod, and one end of the pull rod is located inside the T-slot.

[0046] The first row seat 1 (3) is provided with a first row core at the center of the surface near the mold cavity. The two insert pins 5 pass through the two ends of the first row core respectively. The second row seat 2 (4) has a recess on both sides near the end of the first row core. One end of the first row core is correspondingly set in the recess.

[0047] The working principle of this embodiment is as follows: the two insert pins 5 on the first row seat 1 are respectively inserted into the second row seat 4 and the second row seat 2, and the two insert pins 5 on the first row seat 3 are respectively inserted into the second row seat 4 and the second row seat 2. To ensure that the mold does not collide during mold opening, the self-locking insert 6 ensures that the second row seat 4 and the second row seat 2 do not move backward during mold opening. After the mold opening action of the first row seat 1 and the first row seat 3 is completed, the self-locking insert 6 completely disengages from the self-locking groove 10. The second row seat 2 and the second row seat 4 are opened by hydraulic cylinder drive. During mold closing, the second row seat 4 and the second row seat 2 advance to close the mold first, and then the first row seat 1 and the first row seat 3 close the mold to complete the injection molding action.

[0048] In one embodiment, the second driving element is an inclined guide post, and the second row seat has a strip groove. The inclined guide post passes through the strip groove, and the longitudinal section of the strip groove is a parallelogram.

[0049] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these should all be considered to be within the scope of this specification.
