Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a connecting component mold. Background Technology

[0002] Connector molds are core tools in industrial manufacturing used to produce critical components such as pipes and electronic connectors. Their design integrates materials science, precision machining, and molding technology. These molds transform plastic or metal materials into connectors with specific shapes and functions, such as pipe fittings and wire harness connectors, through processes such as injection molding, stamping, or die casting. The mold structure typically includes modules such as core, cavity, gating system, and demolding mechanism. Among these, the parting surface design, runner optimization, and cooling system layout directly affect molding quality and efficiency. Depending on the characteristics of different materials, molds need to be made of high-hardness alloy steel or stainless steel, and surface treatment technology is used to improve wear resistance and corrosion resistance. In the electronics field, molds need to meet micron-level precision requirements, and complex structures are formed through electrical discharge machining and ultra-precision CNC technology. In pipeline engineering, molds need to balance wall thickness uniformity and sealing performance to ensure the reliability of connectors under high-pressure environments. With the development of automotive lightweighting and 5G communication, connector molds are evolving towards high integration and multi-functionality, becoming an indispensable cornerstone of modern industrial systems.

[0003] However, in the existing technology, the connector molds use a single channel for injection during the injection process, which cannot achieve synchronous injection of multiple pipes, resulting in limited production efficiency. The lack of an effective limiting device when moving the mold makes it possible for slight deviations or excessive movement to occur during operation, affecting product accuracy and quality. Therefore, we need a connector mold. Utility Model Content

[0004] The purpose of this utility model is to provide a connector mold to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connector mold, comprising an upper mold, an injection port at the top of the upper mold, a limiting component on one side of the upper mold, a lower mold at the bottom of the upper mold, a forming component inside the lower mold, the limiting component including a limiting rod fixedly connected to one side of the upper mold, a limiting sleeve fitted onto the outer wall of the limiting rod, a fixing rod fitted onto the inner wall of the limiting sleeve, a connecting rod fixedly connected to the bottom of the upper mold, a connecting sleeve fixedly connected to the top of the lower mold, a fixing plate fixedly connected to one side of the upper mold, an annular groove on one side of the fixing plate, and a bolt inside the annular groove.

[0006] Preferably, the limiting rod forms a limiting structure with the limiting sleeve and the fixing rod, and the inner wall of the limiting sleeve is simultaneously fitted with the limiting rod and the fixing rod.

[0007] Preferably, the upper mold is connected to the connecting sleeve via a connecting rod, and the outer diameter of the connecting rod matches the inner diameter of the connecting sleeve, and the outer wall of the connecting rod is fitted to the inner wall of the connecting sleeve.

[0008] Preferably, the fixing plate is fixed to the lower mold by bolts, and the outer diameter of the bolts matches the inner diameter of the annular groove, and the outer wall of the bolts fits against the inner wall of the annular groove.

[0009] Preferably, the molding component includes an injection channel, which is located at the top of the lower mold. The injection channel is connected to a branch channel, one end of which is connected to a mold cavity. A workpiece is disposed inside the mold cavity, and an ejector pin is disposed at the bottom of the injection channel.

[0010] Preferably, the injection channel is connected to the mold cavity through a branch channel, and one end of the branch channel is connected to the injection channel, while the other end of the branch channel is connected to the mold cavity.

[0011] Preferably, the injection channel has multiple branch channels connected internally, and the branch channels are regularly connected inside the injection channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this connecting mold,

[0013] (1) After the raw material is injected through the injection port, it flows into multiple mold cavities simultaneously and evenly through the injection channel and multiple sub-channels, realizing the molding of multiple workpieces at one time, which significantly improves the molding efficiency of the mold and effectively saves production time. Moreover, after molding, the ejector pin is used to move upward to push the workpiece to complete the demolding. The operation is simple and quick, which can reduce the damage to the workpiece during demolding and ensure stable product quality.

[0014] (2) By loosening the bolts to release the lower mold, the constraint between the molds can be quickly released. When the machine is started and the upper mold moves upward, the limit rod moves inside the limit sleeve. With the contact limit between the limit sleeve and the fixed rod, and the connecting rod moving along the inner wall of the connecting sleeve, multiple protections ensure the stable movement of the upper mold, effectively avoiding deviation and excessive movement, ensuring accurate mold opening and closing, providing stable conditions for subsequent operations, and improving production quality and efficiency.

Detailed Implementation

[0020] 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.

[0021] This utility model embodiment provides a connector mold, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper mold 1 has an injection port 2 at its top. A limiting component 3 is provided on one side of the upper mold 1. A lower mold 4 is provided at the bottom of the upper mold 1. A forming component 5 is provided inside the lower mold 4. The limiting component 3 includes a limiting rod 301, which is fixedly connected to one side of the upper mold 1. A limiting sleeve 302 is sleeved on the outer wall of the limiting rod 301, and a fixing rod 303 is sleeved on the inner wall of the limiting sleeve 302. A connecting rod 304 is fixedly connected to the bottom of the upper mold 1. A connecting sleeve 305 is fixedly connected to the top of the lower mold 4, and a fixing plate 306 is fixedly connected to one side of the upper mold 1. An annular groove 307 is provided on one side of the fixing plate 306, and a bolt 308 is provided inside the annular groove 307. The raw material is injected from the injection port 2, and the raw material flows through the injection channel 501 and then through multiple sub-channels 502 to flow into multiple mold cavities 503 at the same time, which improves the molding efficiency of the mold. After molding, the ejector rod 505 can be activated to move upward and push the workpiece 504 to complete the demolding.

[0022] Furthermore, such as Figure 2As shown, the limiting rod 301 forms a limiting structure with the limiting sleeve 302 and the fixed rod 303. The inner wall of the limiting sleeve 302 is simultaneously fitted with the limiting rod 301 and the fixed rod 303. By setting the limiting sleeve 302, when the limiting rod 301 moves the limiting sleeve 302, the limiting sleeve 302 cannot move when it reaches the outer wall of the fixed rod 303, which improves the limiting effect of the limiting rod 301 on the upper mold 1. Tighten the bolt 308 to release it from the fixation of the lower mold 4, and then start the machine to move the upper mold 1 upward. The upper mold 1 drives the limiting rod 301 to move inside the limiting sleeve 302, so that the limiting rod 301 drives the limiting sleeve 302 to move upward. After the inner wall of the limiting sleeve 302 moves to the outer wall of the fixed rod 303, it cannot move. At the same time, the upper mold 1 drives the connecting rod 304 to move along the inner wall of the connecting sleeve 305, so that the upper mold 1 can move stably to avoid deviation and will not move excessively to affect subsequent operations.

[0023] Furthermore, such as Figure 2 As shown, the upper mold 1 forms a locking structure with the connecting sleeve 305 through the connecting rod 304, and the outer diameter of the connecting rod 304 matches the inner diameter of the connecting sleeve 305. The outer wall of the connecting rod 304 is fitted to the inner wall of the connecting sleeve 305, which allows the connecting rod 304 to move stably along the inner wall of the connecting sleeve 305, thus improving the movement stability of the upper mold 1.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, the fixing plate 306 forms a fixing structure with the lower mold 4 by bolts 308, and the outer diameter of the bolt 308 matches the inner diameter of the annular groove 307, and the outer wall of the bolt 308 fits against the inner wall of the annular groove 307. By setting one end of the bolt 308 to be fixedly connected to the lower mold 4 through the annular groove 307 opened inside the fixing plate 306, the fixing effect of the fixing plate 306 on the lower mold 4 is improved.

[0025] This utility model embodiment provides a connector mold, such as Figure 1 and Figure 4 As shown, the molding component 5 includes an injection channel 501, which is located on the top of the lower mold 4. The injection channel 501 is connected to a branch channel 502, and one end of the branch channel 502 is connected to a mold cavity 503. The mold cavity 503 contains a workpiece 504. A push rod 505 is provided at the bottom of the injection channel 501. The raw material is injected from the injection port 2. The raw material flows through the injection channel 501 and then through multiple branch channels 502 into multiple mold cavities 503 simultaneously, which improves the molding efficiency of the mold. After molding, the push rod 505 can be activated to move upward and push the workpiece 504 to complete demolding.

[0026] Furthermore, such as Figure 4As shown, the injection channel 501 is connected to the mold cavity 503 through the branch channel 502. One end of the branch channel 502 is connected to the injection channel 501, and the other end of the branch channel 502 is connected to the mold cavity 503. This allows the raw material to enter the mold cavity 503 through the branch channel 502 in the injection channel 501, thus improving the injection efficiency.

[0027] Furthermore, such as Figure 4 As shown, the injection channel 501 is internally connected to multiple branch channels 502, and the branch channels 502 are regularly connected inside the injection channel 501. Through the multiple branch channels 502, the raw material can be injected into the injection channel 501 and then flow into the branch channels 502 respectively to enter the mold cavity 503, so that multiple mold cavities 503 can be fed and formed at the same time, which improves the molding efficiency.

[0028] Working principle: The raw material is injected from the injection port 2. The raw material flows through the injection channel 501 and then through multiple branch channels 502 into multiple mold cavities 503 simultaneously, which improves the molding efficiency. After molding, the ejector pin 505 can be activated to move upward and push the workpiece 504 to complete demolding. The bolt 308 is tightened to release it from the fixation of the lower mold 4. The machine is then started to move the upper mold 1 upward. The upper mold 1 drives the limiting rod 301 to move inside the limiting sleeve 302, so that the limiting rod 301 drives the limiting sleeve 302 to move upward. After the inner wall of the limiting sleeve 302 moves to the outer wall of the fixing rod 303, it can no longer move. At the same time, the upper mold 1 drives the connecting rod 304 to move along the inner wall of the connecting sleeve 305, so that the upper mold 1 can move stably to avoid deviation and will not move excessively to affect subsequent operations.
