Description

Technical Field

[0001] This utility model relates to the field of molds, and more particularly to a mold with an attached plug bar tooling. Background Technology

[0002] In the manufacturing of structural components for precision electronic devices such as millimeter-wave radar, the lower housing assembly is a key component, and the efficiency and quality of its injection molding are of paramount importance. Currently, injection molds for producing such lower housing assemblies often require the pre-insertion of multiple (e.g., 8) metal or non-metal inserts into the cavity as structural reinforcement, conductive pathways, or positioning references, depending on the product's structural or functional requirements.

[0003] In existing technologies, the insertion of such inserts is typically done manually. After the mold is opened, operators must individually and precisely place and fix each insert in its designated position within the mold cavity. However, this traditional manual insertion method has significant technical drawbacks. The manual insertion process is tedious and time-consuming, significantly extending the mold opening time and consequently greatly increasing the molding cycle time for a single injection molding process. This directly leads to a decrease in product output per unit time, resulting in low overall production efficiency for both the mold and the injection molding machine, making it difficult to meet the demands of large-scale production.

[0004] Therefore, how to efficiently, accurately, and automatically insert multiple inserts into the mold cavity, thereby significantly shortening the molding cycle, stabilizing the melt temperature, improving production efficiency, and ensuring product quality, has become a key technical challenge that urgently needs to be solved in the injection molding production of millimeter-wave radar lower housing assemblies. Summary of the Invention

[0005] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a mold with a plug-in tooling, which solves the problem that molds with plug-in inserts need to be opened separately and accurately placed and fixed in the specified position of the mold cavity, which makes the mold opening process cumbersome and time-consuming.

[0006] The technical solution of this utility model is as follows: A mold with an attached insert tooling includes a main tooling and an insert. The main tooling includes an upper mold, a lower mold, and a base plate for fixing the lower mold. The lower mold is provided with an ejector structure. A mold cavity is provided between the upper mold and the lower mold. The upper mold is provided with an injection port, and a flow channel is provided between the injection port and the mold cavity. The mold also includes an insert tooling disposed in the mold cavity. The insert tooling includes a fixing plate, a pad, a limiting member, a guide rod, and a spring for resetting the fixing plate. One end of the insert is fixed to the fixing plate, and the other end extends into the mold cavity through the limiting member. Several insert pieces are fixedly disposed in the insert.

[0007] A further feature of this invention is that the guide rod passes through the pad, with one end fixedly connected to the fixed plate and the other end extending into the guide groove provided on the lower mold. The spring is sleeved outside the guide rod, and both ends abut against the lower end face of the fixed plate and the upper end face of the pad.

[0008] A further feature of this invention is that a pressure plate is fixedly mounted on the top of the power strip, and the pressure plate is fixedly mounted on the top end face of the fixing plate by bolts.

[0009] A further feature of this invention is that the power strip includes a push block fixedly connected to a pressure plate, the limiting member has a through hole for the push block to pass through, the through hole and the push block are clearance-fitted, the bottom of the push block is fixedly connected to an insert plate, and the insert plate extends out of the bottom of the pad.

[0010] A further feature of this invention is that the limiting member includes a limiting block disposed at the bottom of the pad.

[0011] A further feature of this invention is that the limiting member also includes an insert positioning block fixedly disposed on the pad, the insert positioning block penetrates the pad, the bottom of the push block extends into the internal cavity of the insert positioning block, the insert is fixedly connected to the bottom of the push block, and the insert extends out of the insert positioning block.

[0012] Further features of this invention include an upper fixed base, a top plate, and a base, wherein the upper mold, the lower mold, the bottom plate, and the base are arranged sequentially from top to bottom.

[0013] Further features of this invention: The ejection structure includes an ejector base plate and an ejector fixing plate disposed between the base plate and the base. A guide post is fixedly disposed between the base plate and the base. The guide post passes through the ejector base plate and the ejector fixing plate. A product ejection rod is provided on the ejector fixing plate. The product ejection rod passes through the base plate and the lower mold and extends into the mold cavity. The ejector base plate is located below the ejector fixing plate. A reset member is provided between the ejector fixing plate and the base plate.

[0014] The beneficial effects of this utility model are as follows: By setting up a strip and a strip tooling, each insert in the mold is integrated into the strip, and the strip is set in the mold cavity. Each insert is integrated into the strip, and the same strip tooling can be used to push the insert into the mold cavity, which improves the overall work efficiency and shortens the operation time compared to manually inserting inserts one by one. The insertion time of inserts is shortened, and product quality defects caused by excessively high storage temperature are eliminated. Attached Figure Description

The guide rod 213 and the spring 214 for resetting the fixed plate 211 are provided. The guide rod 213 passes through the pad 215. One end of the guide rod 213 is fixedly connected to the fixed plate 211, and the other end extends into the guide groove provided on the lower mold 12. The guide rod 213 can move with the mold opening and closing. The spring 214 is sleeved on the outside of the guide rod 213, and both ends abut against the lower end face of the fixed plate 211 and the upper end face of the pad 215 to realize the extraction of the insert during mold opening and realize the secondary core pulling action together with the mold opening action.

[0022] Furthermore, it also includes a limiting post 216, which has a T-shaped structure and is correspondingly inserted into the countersunk hole on the pad 215.

The insert extends out of the insert positioning block 232. The push block 222 can drive the insert to slide in the internal cavity of the insert positioning block 232.

[0024] The power strip 3 is fixedly provided with several inserts. In this embodiment, the power strip 3 integrates eight inserts. After the power strip 3 is installed, the robotic arm clamping fixture inserts the power strip fixture into the mold.

[0025] The limiting member 23 is fixedly installed on the top of the pad 215, and a travel gap is left between the top of the limiting member 23 and the bottom of the fixing plate 211. The gap is the distance of the downward movement of the fixing plate 211 to control the pushing stroke of the insert. The limiting member 23 is provided with a through hole for the push block 222 to pass through. The through hole and the push block 222 are fitted with a clearance.
