[0002] Currently, in the field of injection molding, the sprue of injection molds is usually designed as an irregular gate, which typically consists of two gates positioned at an angle. Existing methods for processing irregular gates usually involve dividing the gate block into two symmetrical parts, processing each part separately to form half of the irregular gate, and then joining the two parts together to form a complete irregular gate. However, assembly errors can occur during the joining process, resulting in gates with low precision formed by this method. Summary of the Invention

[0017] Preferably, the step of processing the second region to form the second gate includes:

[0018] The gate block is placed vertically so that the end of the second zone away from the first zone faces upward.

[0019] The second electrode is used to perform electrical discharge machining from the end of the second region away from the first region downwards until it connects with the first gate, so as to form a second gate that is consistent with the extension direction of the gate block.

[0020] Preferably, the step of providing a gate block to be filled, and dividing the gate block into a first zone and a second zone includes:

[0021] The gate block is divided into a first region and a second region along the preset directions of the first gate and the second gate, respectively; wherein the length of the first region along the preset direction of the first gate is less than the length of the second region along the preset direction of the second gate.

[0022] Preferably, the step of providing a gate block to be filled, and dividing the gate block into a first zone and a second zone includes:

[0023] A straight bar-shaped gate block is provided, one end of which has an inclined wall. The area where the inclined wall is located is divided into a first region, and the area outside the inclined wall is divided into a second region.

[0024] Preferably, the step of filling the filler block back into the filler slot includes:

[0025] The filler block is placed back into the filling groove, so that the filler block completely seals the filling groove and a joint is formed between the outer periphery of the filler block and the groove wall of the filling groove;

[0026] Welding is performed along the joint to secure the filler block within the filler groove.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0051] In this invention, the descriptions of directions such as "up," "down," "front," "back," "left," and "right" are as follows: Figure 4 The directions shown are for reference only and are used to interpret the location. Figure 4 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0052] This invention provides a method for processing irregularly shaped gates and an injection mold.

[0053] Reference Figure 1 This is a schematic flowchart of the first embodiment of the fine needle processing method of the present invention. The irregular gate processing method includes the following steps:

[0054] Step S10: Provide a gate block to be gated, and divide the gate block into a first area and a second area;

[0055] Reference Figure 4 The gate block 100 extends vertically. Along this vertical direction, the gate block 100 is divided into a first zone 10 and a second zone 20, with the first zone 10 located below the second zone 20. By dividing the gate block 100 into the first zone 10 and the second zone 20, the first zone 10 is used to form the first gate 50, and the second zone 20 is used to form the second gate 60, facilitating the processing of the gate block 100 to form the first gate 50 and the second gate 60.

[0056] Step S20: On the gate block, a portion of the structure is removed from the second region near the first region to form a filling groove; the opening of the filling groove faces outward, and the portion of the structure removed from the gate block forms a filling block;

[0057] Reference Figure 4 and Figure 7A filling groove 30 is formed in the gate block 100. The filling groove 30 is formed by removing part of the structure in the second region 20 near the first region 10 on the gate block 100. The opening of the filling groove 30 is set outward, that is, to the right. The filling groove 30 is set to facilitate the processing to form the first gate 50.

[0058] After the filling groove 30 is designed, it can be machined into place by a CNC machine tool. The CNC machine tool has a high degree of automation, which greatly reduces the labor intensity of workers. In addition, the CNC machine tool has high machining accuracy, which can realize mass production and make product quality easy to control.

[0059] Step S30: Process one wall of the filling groove to form a first gate;

[0060] Reference Figure 9 After the machining tool extends into the filling groove 30, it is positioned by one of the groove walls of the filling groove 30, and the groove wall is machined to form the first gate 50. Positioning by one of the groove walls of the filling groove 30 improves machining accuracy and ensures the machining accuracy of the first gate 50. The machining tool can be a drill bit, electrode, or other machining tool capable of machining the groove wall of the filling groove 30 to form the first gate 50.

[0061] Step S40: Fill the filling block back into the filling groove;

[0062] The gate block 100 has a portion of its structure removed to form a filling groove 30, and the removed portion forms a filling block 40. Therefore, the shape of the filling block 40 matches the shape of the filling groove 30. After processing to form the first gate 50, the filling block 40 is filled back into the filling groove 30. The shape of the filling block 40 matches the shape of the filling groove 30, and the filling block 40 can reliably seal the filling groove 30, facilitating processing to form the second gate 60.

[0063] In other embodiments, the gate block 100 itself has a filling groove 30, and a filling block 40 can be made in accordance with the shape of the filling groove 30 and the filling block 40 can be embedded in the filling groove 30.

[0064] Step S50: The second area is processed to form a second gate; the second gate is set at an angle to the first gate, and the second gate is connected to the first gate to form an irregular gate.

[0065] Reference Figure 6 and Figure 10After the filling block 40 fills back into the filling groove 30, the second area 20 is processed to form a second gate 60. The second gate 60 is connected to the first gate 50, and the second gate 60 and the first gate 50 are set at an angle. The second gate 60 and the first gate 50 cooperate to form an irregular gate, thereby realizing the formation of an irregular gate by the gate block 100.

[0066] The irregular gate processing method of this invention divides the gate block 100 into a first region 10 and a second region 20. The first region 10 is used to form a first gate 50, and the second region 20 is used to form a second gate 60, facilitating the processing of the gate block 100 to form the first gate 50 and the second gate 60. Partial structure is removed from the gate block 100 to form a filling groove 30. The filling groove 30 facilitates the processing of the first gate 50, and positioning is achieved through one wall of the filling groove 30, improving processing accuracy and ensuring the processing precision of the first gate 50. Furthermore, after processing the first gate 50, a filling block 40 is placed back into the filling groove 30. The shape of the filling block 40 matches the shape of the filling groove 30, reliably sealing the filling groove 30 and facilitating processing to form the second gate 60. Both the first gate 50 and the second gate 60 are formed in a single processing step, avoiding assembly errors caused by splicing and ensuring the processing precision of the irregular gate.

[0067] Reference Figure 2 This is a flowchart illustrating a second embodiment of the processing method for irregularly shaped gates according to the present invention. Based on the first embodiment described above, refer to... Figure 6 and Figure 7 The first area and the second area are connected;

[0068] The first zone 10 is located below the second zone 20, and the upper end of the first zone 10 is connected to the second zone 20.

[0069] Step S30 includes:

[0070] Step S31: Select a groove wall located at the junction of the first area and the second area on the filling groove as the groove wall to be processed;

[0071] Step S32: Process the wall of the filling groove to form the first gate.

[0072] A wall 31 to be processed is selected on the filling groove 30. The wall 31 is located at the junction of the first zone 10 and the second zone 20. The wall 31 is processed to form the first gate 50. The wall 31 is used for positioning to improve processing accuracy and ensure the processing accuracy of the first gate 50. Furthermore, the wall 31 is located at the junction of the first zone 10 and the second zone 20, that is, adjacent to the first zone 10. This facilitates the insertion of processing tools into the filling groove 30 to form the first gate 50, reduces the processing length, and helps to improve processing efficiency.

[0073] Reference Figure 3 This is a flowchart illustrating the third embodiment of the processing method for irregularly shaped gates of the present invention. Based on the second embodiment described above, step S32 includes:

[0074] Step S321: The gate block is placed at an angle so that the wall of the groove to be processed faces upward;

[0075] Step S322: The first electrode is used to perform vertical downward discharge machining on the wall of the tank to be processed, so as to form the first gate which is set at an angle to the extension direction of the gate block.

[0076] Reference Figure 9 The extension direction of the gate block 100 is the vertical direction, and the first gate 50 is set at an angle to the vertical direction, that is, the first gate 50 is set tilted to the left from top to bottom.

[0077] When machining inclined gates, using a drill bit is difficult due to the difficulty in positioning and the risk of breakage. Electrode machining, on the other hand, utilizes the high temperature generated by a momentary spark discharge between the tool electrode and the workpiece electrode to melt and erode the surface material of the workpiece. Electrode machining machine tools generally consist of a pulse power supply, an automatic feed mechanism, a machine body, and a working fluid circulation and filtration system. The workpiece is fixed on the machine tool table. The pulse power supply provides the energy required for machining, with its two poles connected to the tool electrode and the workpiece, respectively. When the tool electrode and workpiece approach each other in the working fluid under the drive of the feed mechanism, the voltage between the electrodes breaks down the gap, generating a spark discharge and releasing a large amount of heat. The workpiece surface absorbs this heat, reaching a very high temperature (above 10,000°C), and some of the material is eroded away due to melting or even vaporization, forming a tiny pit. The working fluid circulation and filtration system forces clean working fluid through the gap between the tool electrode and the workpiece at a certain pressure, promptly removing the electro-erosion products and filtering them out of the working fluid. As a result of repeated discharges, numerous pits are created on the workpiece surface. Driven by the feed mechanism, the tool electrode descends continuously, and its contour shape is "copied" onto the workpiece. Although the tool electrode material is also etched away, its speed is much slower than that of the workpiece material.

[0078] Therefore, using the first electrode 200 to perform electrical discharge machining on the tank wall 31 can improve the efficiency of forming the first gate 50 and ensure that the accuracy of the first gate 50 meets the processing requirements. Tilting the gate block 100 so that the tank wall 31 faces upwards allows the first electrode 200 to perform electrical discharge machining vertically downwards, facilitating the removal of electro-erosion products and improving processing efficiency. Furthermore, the vertical downward operation of the first electrode 200 facilitates control of the processing rate of the first gate 50, thus ensuring the processing accuracy of the first gate 50.

[0079] Specifically, when the first electrode 200 is used for vertical downward discharge machining of the groove wall 31 to be machined, the first electrode 200 does not contact the other groove walls of the filling groove 30. This avoids interference between the other groove walls of the filling groove 30 and the discharge of the first electrode 200, thus improving the machining accuracy of the first gate 50. At the same time, it also facilitates the subsequent machining of the second gate 60. The first gate 50 is tapered in the direction away from the filling groove 30, which facilitates demolding and improves demolding efficiency.

[0080] Reference Figure 3 Step S50 includes:

[0081] Step S51: Place the gate block vertically so that the end of the second region away from the first region faces upward;

[0082] The second gate 60 extends in the same direction as the gate block 100, that is, the second gate 60 extends in the vertical direction. The gate block 100 is set vertically so that the first region 10 is set vertically, and the end of the second region 20 away from the first gate 50 is set upward, which facilitates the processing to form the second gate 60.

[0083] Step S52: Using the second electrode, discharge machining is performed downward from the end of the second region away from the first region until it connects with the first gate, so as to form a second gate that is consistent with the extension direction of the gate block.

[0084] Reference Figure 10 The second gate 60 is also formed by electrical discharge machining using electrodes to ensure its precision. The second electrode 300 performs electrical discharge machining downwards from the end of the second region 20 away from the first region 10, that is, the second electrode 300 performs electrical discharge machining downwards from the upper end of the second region 20 until it connects with the first gate 50 to form the second gate 60. The second gate 60 and the first gate 50 are connected to form a shaped gate.

[0085] Specifically, refer to Figures 6 to 8The second gate 60 includes a first connecting portion 61 and a second connecting portion 62. The first connecting portion 61 is located on the gate block 100, and the second connecting portion 62 is located on the filler block 40. The second electrode 300 performs electrical discharge machining downwards to sequentially form the first connecting portion 61 and the second connecting portion 62. The first connecting portion 61 and the second connecting portion 62 cooperate to form the second gate 60.

[0086] Reference Figure 6 Step S10 includes:

[0087] Step S11: Divide the gate block into a first region and a second region along the preset directions of the first gate and the second gate in the irregular gate respectively; wherein, the length of the first region along the preset direction of the first gate is less than the length of the second region along the preset direction of the second gate.

[0088] The gate block 100 is divided into a first zone 10 and a second zone 20. Specifically, the gate block 100 is divided into a first zone 10 and a second zone 20 along the preset direction of the first gate 50 and the second gate 60, respectively. The length of the first zone 10 along the preset direction of the first gate 50 is less than the length of the second zone 20 along the preset direction of the second gate 60. In the irregular gate, the length of the first gate 50 is less than the length of the second gate 60. Processing the shorter first gate 50 first and then the longer second gate 60 can reduce the size of the filling groove 30. At the same time, it can also reduce the time required to fill the filling block 40 back into the filling groove 30, improve the efficiency of filling the filling block 40 back into the filling groove 30, and thus improve the processing efficiency.

[0089] Reference Figures 4 to 6 Step S10 includes:

[0090] Step S12: Provide a straight bar-shaped gate block to be gated, one end of the gate block having an inclined wall, the area where the inclined wall is located is divided into the first area, and the area outside the inclined wall is divided into the second area.

[0091] The gate block 100 is a straight strip extending vertically. An inclined wall 70 is located at the lower end of the gate block 100 and slopes downwards to the left. The area containing the inclined wall 70 is divided into a first zone 10, and the area outside the inclined wall 70 is divided into a second zone 20. The inclined wall 70 allows operators to more clearly and intuitively distinguish between the first zone 10 and the second zone 20, thereby enabling rapid positioning of the filling groove 30 and improving its processing efficiency.

[0092] Reference Figures 4 to 7 Step S40 includes:

[0093] Step S41: Place the filling block back into the filling groove so that the filling block completely seals the filling groove and forms a joint between the outer periphery of the filling block and the groove wall of the filling groove.

[0094] Step S42: Weld along the joint to fix the filler block in the filler groove.

[0095] The filler block 40 is placed back into the filler groove 30, which is formed by removing the filler block 40 from the gate block 100. Therefore, the filler block 40 has a shape consistent with the filler groove 30, and it can completely seal the filler groove 30. After the filler block 40 is placed back into the filler groove 30, a joint is formed between the outer periphery of the filler block 40 and the groove wall of the filler groove 30. Welding is performed along the joint to ensure that the filler block 40 is stably and reliably fixed in the filler groove 30. Welding is used to connect the outer periphery of the filler block 40 to the groove wall of the filler groove 30, which improves the connection stability between the filler block 40 and the filler groove 30 and prevents the filler block 40 from detaching from the filler groove 30.

[0096] Specifically, laser welding can be used to fix the filler block 40 within the filler groove 30. Laser welding has advantages such as high speed, large depth, small deformation, and precise positioning. In other embodiments, arc welding or other welding methods can be used as needed. This invention does not limit the specific welding method.

[0097] Reference Figure 4 After step S42, the following steps are also included:

[0098] Step S43: Grind the weld formed after welding along the joint.

[0099] Welding along the joint will form a weld seam, which will affect the surface finish of the gate block 100 and the fit between the gate block 100 and other structures of the injection mold, causing interference. Grinding the weld seam improves the surface finish of the gate block 100, making it easier to use. After grinding, the surface finish is checked and controlled to be below VDI14.

[0100] Reference Figure 4 The filling groove is a strip-shaped filling groove that is consistent with the extension direction of the gate block, and the adjacent two groove walls of the filling groove are smoothly connected.

[0101] The filling groove 30 is strip-shaped and extends in the same direction as the gate block 100. The filling groove 30 extends vertically, and adjacent walls of the filling groove 30 are smoothly connected to avoid sharp joints that could pose safety hazards, thus improving the safety and reliability of the filling groove 30. The filling block 40 has the same shape as the filling groove 30, meaning adjacent side walls of the filling block 40 are smoothly connected, making its use safer and more convenient.

[0102] In addition, the present invention also provides an injection mold, which includes a gate block 100. The gate block 100 is processed using the irregular gate processing method described above. The irregular gate processing method is specifically referred to in the above embodiments. Since the injection mold adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0103] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
