Description

Technical Field

[0001] This utility model relates to the field of wire clamp production mold technology, and in particular to a micro inverter welding wire clamp production mold. Background Technology

[0002] Microinverter welding clamps are specialized tools / accessories used for the installation and connection of microinverters in photovoltaic systems. They are mainly used to safely and reliably connect the cables between photovoltaic modules and microinverters. Existing clamps for this purpose are mostly made of nylon material and manufactured through integrated injection molding.

[0003] Because of its relatively simple structure, its corresponding mold only requires simple straight-line injection molding. However, conventional injection molding often involves opening the cavity at one end and flowing to the other end, resulting in a long path. In addition, air will exist in the cavity after mold closing, which will hinder the flow of hot melt during injection. At the same time, some air will seep in, forming bubbles and affecting the appearance and quality of the product. Furthermore, the mold is prone to slight bumps and deformations during long-term use, which can lead to leakage problems during injection molding. There is a lack of testing equipment before injection molding after mold closing to promptly test the airtightness of the cavity and avoid affecting the overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a micro-inverter welding clamp production mold that can ensure that the hot melt can be evenly distributed to both sides during injection molding and uniformly distributed in the cavity for cooling and shaping. In addition, it can avoid the formation of bubbles due to gas residue while accelerating the injection molding rate. Furthermore, it can indirectly detect the airtightness of the cavity to avoid leakage problems during injection molding that would affect the overall production efficiency.

[0005] To achieve the above objectives, a micro-inverter welding wire clamp production mold is provided, comprising: a base, a top seat mounted directly above the base, a lower mold fitted at the top center of the base, an upper mold slidably fitted at the bottom center of the top seat, cavities corresponding to the upper and lower molds on opposite sides, a wire clamp body injection molded and shaped within each cavity, synchronous linear drive modules symmetrically mounted in a cross shape on the top of the top seat, the bottom output ends of the synchronous linear drive modules slidingly through a slide block and correspondingly fitted and fixed with the upper mold, an injection hole opening upward at the center of the upper mold cavity, an injection bellows tube fixedly connected to the top of the injection hole, an injection molding machine fixedly connected to the top of the injection bellows tube, the injection molding machine fitted and fixedly mounted on the upper part of the top seat, an vent opening upward at the front end of the upper mold cavity, a high-temperature resistant solenoid valve fitted within the vent opening, and the top of the vent opening connected to... A vacuum hose is fixedly connected to the top of the vacuum hose, and a small vacuum pump is fixedly connected to the rear of the small vacuum pump. The rear of the small vacuum pump is fitted and fixed to the injection molding machine. Ring seats are fitted and fixed at the four outer corners of the base and the top seat. Supports are fixedly connected to the upper and lower opposite sides of the ring seats. An injection hole is opened at the center of the upper mold cavity to perform injection molding. This ensures that the hot melt can be evenly distributed to both sides to fill the cavity and cool and solidify. In addition, an exhaust hole is opened at the tail end of the upper mold cavity and works with the vacuum hose and the small vacuum pump to extract the air in the cavity after mold closing and form a vacuum. This avoids the formation of air bubbles due to gas residue and speeds up the injection molding rate. The small vacuum pump can also indirectly detect the airtightness of the cavity by monitoring the pressure change after vacuuming, thus preventing leakage problems during injection molding that would affect the overall production efficiency.

[0006] According to the aforementioned micro-inverter welding wire clamp production mold, a limiting groove is provided on the outer side of the connection between the upper mold and the output end of the synchronous linear drive module. A washer ring is slidably fitted inside each limiting groove, and the inner side of each washer ring corresponds to the slidable fit with the output end of the synchronous linear drive module. The top of each washer ring is fixedly connected to a top seat. This provides positioning and buffering for the opening movement of the upper mold.

[0007] According to the micro-inverter welding wire clamp production mold, a limiting plate is horizontally fitted and fixed on the outer side of the synchronous linear drive module to ensure the uniformity and stability of the output direction of each drive module.

[0008] According to the aforementioned micro-inverter welding wire clamp production mold, a sliding film is attached and covered to the top inner side of the lower mold, and the outer surface of the sliding film corresponds to the upper mold in a sliding fit. This avoids frictional wear in the vertical direction during mold closing.

[0009] According to the aforementioned micro-inverter welding wire clamp production mold, annular grooves are formed on the outer sides of the injection-molded corrugated pipe and the vacuum hose, corresponding to the bottom of the top seat. The outer edges of the bottom of the annular grooves are rounded. This facilitates the retraction of both components into the annular grooves for sealing and preservation during mold opening, preventing damage from external collisions.

[0010] According to the micro-inverter wire clamp production mold, the inner surface of the cavity is polished to prevent adhesion from affecting demolding.

[0011] According to the micro-inverter welding wire clamp production mold, a ring of elastic padding is fixed around the bottom outer edge of the base. This prevents the side of the base plate from causing indentations on the placement surface during placement.

[0012] According to the aforementioned micro-inverter welding wire clamp production mold, an elastic sealing gasket is fixedly attached to the bottom of the upper mold, and the bottom of the elastic sealing gasket is pressed and sealed against the lower mold. This provides elastic buffering during mold closing and improves the airtightness of the mold during closing.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] In this invention, an injection hole is opened at the center of the upper mold cavity to perform injection molding. This ensures that the hot melt can be evenly distributed to both sides and filled evenly within the cavity for cooling and solidification. Additionally, an exhaust hole is opened at the tail end of the upper mold cavity, which, together with a vacuum hose and a small vacuum pump, extracts the air from the cavity after mold closing and creates a vacuum. This prevents residual gas from forming bubbles and accelerates the injection rate. Furthermore, the small vacuum pump can indirectly detect the airtightness of the cavity by monitoring the pressure change after vacuuming, thus preventing leakage during injection molding and ensuring overall production efficiency.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
