Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold spring block structure. Background Technology

[0002] The spring block in an injection mold is a movable molding component. Its core function is to solve the demolding problem of complex plastic parts through lateral movement, while improving the automation level and production efficiency of the mold.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Front Mold Spring Block Structure for Injection Molds," and the patent application number is 202020247274.1. This utility model relates to the field of injection mold technology, specifically to a front mold spring block structure for injection molds, including a rear mold and a front mold. The front mold has a cavity on the side facing the rear mold, and multiple ejection openings are provided on the front mold. These ejection openings are through slots that penetrate the front mold. The ejection openings are located around the cavity and are connected to the cavity. The ejection openings contain... The ejector block, capable of filling the space within its groove, can reciprocate horizontally along the length of the groove. One end of the ejector block always faces the rear mold and serves as the unloading end. The other end of the ejector block is equipped with a spring-loaded structure containing an elastic element. When the elastic element is in its normal state, the unloading end of the ejector block corresponding to the elastic element is outside the groove. The unloading end of the ejector block is a flat, closed structure. This invention can prevent injection molded parts from accumulating in the front mold cavity, thereby improving production efficiency. However, the aforementioned arrangement on the outside of the device requires a large area and occupies considerable space.

A slide cylinder 42 is fixedly connected to the top of the bottom connecting block 41. A sliding sleeve 43 is slidably connected to the outside of the slide cylinder 42.

A spring plate 49 is fixedly connected to the top of the sliding sleeve 43. The top of the spring plate 49 is in contact with the bottom of the bottom template 2. A triggering mechanism 5 is provided on the outside of the bottom connecting block 41.

[0035] refer to Figure 5 The triggering mechanism 5 includes a micro motor 51, which is fixedly connected to the top of the base plate 1. A threaded rod 52 is fixedly connected to the output end of the micro motor 51. A transmission sleeve 53 is threadedly connected to the surface of the threaded rod 52. A strike rod 54 is fixedly connected to the outside of the transmission sleeve 53. A slide rod assembly 55 is fixedly connected to the bottom of the strike rod 54. A limit slide rail 56 is slidably connected to the bottom of the slide rod assembly 55. The bottom of the limit slide rail 56 is fixedly connected to the top of the bottom connecting block 41.

[0036] As a technical optimization of this utility model, the triggering mechanism 5 enables the overall structure to be triggered by an external electrical signal, eliminating the need for manual operation, effectively reducing the workload of staff and providing convenience for users.

[0037] refer to Figure 5 Triangular blocks 6 are fixedly connected to both sides of the limiting slide rail 56, and the bottom of the triangular blocks 6 is fixedly connected to the top of the bottom connecting block 41.

[0038] As a technical optimization of this utility model, the setting of the triangular block 6 can reinforce the limiting slide rail 56 to ensure its stable operation and prevent its position from shifting.

[0040] As a technical optimization of this utility model, the rubber pad 7 can protect the impact rod 54, reduce its wear, and ensure that it is more durable.

[0045] The working principle and usage process of this utility model are as follows: First, the external control system sends an electrical signal to the micro motor 51 to drive it to start. The micro motor 51 drives the threaded rod 52 to rotate, and the transmission sleeve 53 on the surface of the threaded rod 52 moves axially, thereby pushing the impact rod 54 to move horizontally. The slide rod assembly 55 at the bottom of the impact rod 54 slides in the limiting slide rail 56 to ensure accurate movement direction and avoid deviation. The triangular block 6 reinforces the limiting slide rail 56 to improve stability. The impact rod 54 moves horizontally to contact the fixed plate 47, causing it to disengage from the slot 45. The spring assembly 44 is triggered to extend, causing it to push the slide sleeve 43 to move upward. The slide sleeve 43 pushes the spring plate 49 to move upward, thus ejecting the mold after the injection molding operation is completed.

[0046] In summary, this injection mold spring block structure, through its spring block mechanism, changes the traditional practice of placing spring blocks on the outside of the device, which has strict site requirements. It effectively saves space requirements, reduces workspace, and provides convenience for users.
