Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a quick interchange plate for trial molding of multi-color molds. Background Technology

[0002] In injection molding, the impact of numerous mold trials cannot be ignored. Each trial represents a comprehensive test of the mold and the process, but an excessive number of trials can also bring a series of negative consequences.

[0003] Because the company's trial molding machines for commercial molds cannot be the same model as the customers' mass production molding machines, each multi-color mold requires a trial hot runner system. When multiple molds need trial molding, the types of hot runners used in the trial molding are numerous, resulting in high costs. Traditional trial molding and mold changing require disassembling the hot runner plate and replacing the trial hot runner, which is time-consuming.

[0004] From a cost perspective, the number of injection mold trials undoubtedly increases production costs. Trial molding consumes significant amounts of raw materials, manpower, and time. Especially after new product development or mold modifications, the number of trials can increase exponentially due to the need for multiple adjustments to process parameters and mold structure. This not only increases direct production costs but may also lead to indirect cost increases due to extended production cycles, such as warehousing expenses and capital tied up.

[0005] Excessive trial molding can also negatively impact product quality. During frequent trials, the mold itself may wear down or be damaged, leading to a decrease in the product's dimensional accuracy and surface quality. Furthermore, fluctuations in process parameters during trials can cause instability in product performance, thereby increasing the defect rate. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a quick-change plate for trial molding of multi-color molds. It features a simple structure, time and labor savings, and high efficiency. It enables independent and precise delivery of molten plastic of different colors / materials and can be quickly and stably installed on injection molding machines, greatly simplifying the trial molding process for multi-color molds and improving trial molding efficiency and success rate.

[0007] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A quick-change plate for trial molding of multi-color molds includes a trial mold exchange plate. The upper end of the trial mold exchange plate is provided with a heating resistor connector. A pair of trial mold hot runners I and II are provided on one side end face of the trial mold exchange plate in an alternating manner. One end of the trial mold hot runners I and II is provided with a trial mold glue inlet point. A glue heating runner is provided between the trial mold hot runners I and II and the heating resistor connector. The other end of the trial mold hot runners I and II is provided with a customer glue inlet point.

[0008] Preferably, the line connecting the center points of the two customer injection points is on the longitudinal center line of the mold exchange plate, and the line connecting the center points of the two mold injection points and the customer injection points on the hot runner I of the mold is on the transverse center line of the mold exchange plate.

[0009] Preferably, the other end face of the trial mold interchange plate is provided with a glue inlet connector that is connected to the customer's glue inlet point.

[0010] Preferably, the glue inlet joint is provided with several hydraulic mold encoders on both sides.

[0011] Preferably, the hydraulic mold encoder and the mold exchange plate are provided with a T-shaped groove that is integrated with the mold exchange plate, and a sliding groove mounting block is provided between the T-shaped groove and the hydraulic mold encoder.

[0012] (1) Staggered dual-channel design: The hot runner I and hot runner II of the trial mold are arranged in an "alternating" pattern on the side end face of the plate. This layout allows for the efficient arrangement of two independent runners within a limited space, avoiding interference and reserving space for their respective heating and control systems.

[0013] (2) Symmetrical longitudinal centerline: The line connecting the center points of the two customer glue injection points is located on the longitudinal center line of the trial mold exchange plate.

[0014] Significance: This ensures that the entire interchangeable plate is balanced in terms of force. When the clamping force and injection pressure are applied simultaneously by the two injection molding machine nozzles, their resultant force acts on the centerline of the plate, which can prevent the plate from deflecting or stress concentration, thus ensuring structural stability and reliable sealing.

[0015] (3) Alignment of horizontal center lines: The line connecting the center points of the two trial mold injection points, and the line connecting the customer injection point on the hot runner I of the trial mold with the corresponding point on the other side, are all on the transverse center line of the trial mold interchange plate.

[0016] Significance: This defines the mounting reference on the mold side. It means that the customer's mold gate can be designed according to a standard center distance. As long as the customer's mold meets this standard, this interchangeable plate can be seamlessly connected, achieving the goal of "one plate for multiple uses" for rapid interchangeability. At the same time, aligning an input point and an output point on a horizontal line simplifies the design of the internal flow channel, making it more regular and reducing dead zones in the flow.

[0017] This invention can achieve the following effects: This invention provides a quick-change plate for trial molding of multi-color molds. Compared with existing technologies, it features simple structure, time and labor saving, and high efficiency. It enables independent and precise delivery of molten plastic of different colors / materials and can be quickly and stably installed on injection molding machines, greatly simplifying the trial molding process of multi-color molds and improving trial molding efficiency and success rate.

[0018] (1) High efficiency and speed: Quick mold change: The standardized hydraulic mold clamping device and T-slot design significantly reduce the installation and disassembly time of interchangeable plates from several hours to tens of minutes.

[0019] Simplified trial molding: There is no need to equip each multi-color mold with a complex hot runner system. Simply connect the mold to this standardized interchangeable plate to start trial molding, which greatly shortens the new mold development cycle.

[0020] (2) High precision and stability: Precise temperature control: The integrated heating system and temperature control interface ensure the temperature uniformity of the molten adhesive during the delivery process, avoiding material degradation or flowability problems caused by temperature fluctuations, and ensuring the quality of trial molding.

[0021] Stable structure: The longitudinal and transverse centerline design ensures balanced force and accurate positioning, avoiding glue leakage or product defects caused by installation deviations.

[0022] (3) Versatility and economy: One plate for multiple uses: As long as the customer's mold gate design meets the standard of the interchangeable plate (such as center distance), the same interchangeable plate can be used for trial molding of multiple different multi-color molds, reducing the company's equipment investment costs.

[0023] Reduce mold costs: When customers develop new molds, the hot runner section can be simplified, requiring only the design of standard docking interfaces, thus reducing the complexity and manufacturing costs of their molds.

[0024] (4) Easy to operate: All interfaces (heating, glue injection) are integrated on one board, with a clear layout and convenient connection, reducing the possibility of operational errors and reducing the dependence on the operator's skills. Attached Figure Description

[0030] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0031] Example: Figure 1-4 As shown, a quick-change plate for trial molding of multi-color molds includes a trial mold exchange plate 1. A heating resistor connector 3 is provided at the upper end of the trial mold exchange plate 1. A pair of staggered trial mold hot runners I 8 and II 9 are provided on one side of the trial mold exchange plate 1. A trial mold injection point 10 is provided at one end of each trial mold hot runner I 8 and II 9. A glue heating runner 7 is provided between the trial mold hot runners I 8 and II 9 and the heating resistor connector 3. A customer injection point 11 is provided at the other end of each trial mold hot runner I 8 and II 9. The line connecting the center points of the two customer injection points 11 is on the longitudinal centerline of the trial mold exchange plate 1, and the line connecting the center points of the two trial mold injection points 10 and the customer injection points 11 on the trial mold hot runner I 8 is on the transverse centerline of the trial mold exchange plate 1. On the other end face of the trial mold interchange plate 1, there are glue inlet connectors 2 that are connected to the customer glue inlet point 11. Several hydraulic mold clamps 5 are provided on both sides of the glue inlet connectors 2. There is a T-slot 4 that is integrated with the trial mold interchange plate 1 between the hydraulic mold clamps 5 and the trial mold interchange plate 1. There is a sliding groove mounting block 6 between the T-slot 4 and the hydraulic mold clamps 5.

[0032] Working principle and workflow Installation phase: Align the entire trial mold interchange plate assembly with the mounting position of the injection molding machine plate through its T-slot 4 and slide mounting block 6.

[0033] The hydraulic system is activated, driving the hydraulic mold clamp 5 to slide and clamp along the T-slot 4, firmly fixing the interchangeable plate onto the injection molding machine. This process is fast and precise.

[0034] Connection and preheating phase: Connect the nozzles of the two injection molding machines to the two glue inlet connectors 2 respectively.

[0035] Connect the heating resistor connector 3 to the external temperature control box to preheat the glue heating channel 7 and the trial mold hot runner I 8 and trial mold hot runner II 9 until the set process temperature is reached.

[0036] Trial molding and injection stage: First color / material: Injection molding machine A injects molten plastic through the injection joint 2, flows through the customer's injection point 11, and enters the trial mold hot runner I 8. Under the heat preservation of the glue heating runner 7, the molten plastic flows stably and is finally injected into the designated cavity of the customer's mold from the trial mold injection point 10.

[0037] Second color / material: Injection molding machine B synchronously or sequentially injects another type of molten plastic through another system (injection joint → customer injection point → trial mold hot runner II → glue heating runner → trial mold injection point) into another designated cavity of the customer's mold.

[0038] The two flow channels are completely independent and do not interfere with each other, enabling precise co-injection or sequential injection of multi-color materials.

[0039] In summary, this quick-change plate for multi-color mold trial molding features simple structure, time and labor saving, and high efficiency. It enables independent and precise delivery of molten plastic of different colors / materials and can be quickly and stably installed on injection molding machines, greatly simplifying the trial molding process for multi-color molds and improving trial molding efficiency and success rate.
