Description

TECHNICAL FIELD

[0001] The utility model relates to the field of injection molding, especially to a low-pressure injection molding equipment. BACKGROUND

[0002] Low-pressure injection molding is a new injection molding process between potting and high-pressure injection molding, which injects hot melt adhesive into a mold at a very low injection pressure of 1.5-40 bar and can be quickly solidified and formed within a few seconds to a few minutes. It has many advantages, such as short process cycle, high yield, excellent waterproof sealing, IP67 or higher waterproof sealing level, excellent vibration resistance, solvent resistance, and environmental temperature resistance.

[0003] Single-gun design makes the injection molding process relatively simple, and the material filling rate is limited, making it difficult to complete the injection molding process of multiple products in a short time. In the face of a large number of orders, the production rhythm is slow, resulting in a significant extension of the production cycle, making it difficult to keep up with the rapid growth of market demand, and unable to achieve rapid delivery of products. In addition, when faced with complex or diversified product production needs, single-gun injection molding equipment is difficult to adjust production strategies flexibly, and production time cannot be efficiently utilized, which not only reduces production efficiency, but also continuously increases production costs.

The adjusting mechanism adjusts the height of the discharge end of the injection molding gun to the bottom of the processing station and the spacing between multiple injection molding guns.

[0007] The height of the injection molding gun and the spacing between multiple injection molding guns are adjusted using the adjusting mechanism, so that the height of the injection molding gun adapts to the injection molding hole height of the processed product, and the discharge ends of multiple injection molding guns can process multiple products one by one. The provision of multiple injection molding guns can increase the utilization rate and processing efficiency of the overall rack and equipment, so that multiple products can be injected at the same time, and multiple injection molding guns can share the same feeding pipe, improving the utilization rate of the feeding pipe.

[0008] Preferably, the adjusting mechanism comprises a slide rail and slide seats, the number of the slide seats is set according to the number of the injection guns, and the slide seats are slidably arranged on the slide rail.

[0009] The slide seats are slidably arranged on the slide rail, so that the distance between the injection guns can be adjusted.

[0013] The arrangement of the support table and the two slide seats can improve the movement stability of the injection gun, provide better support for the injection gun, and avoid the arrangement of the adjusting mechanism directly below the injection gun, so that the injection gun can be arranged closer to the processing platform, thereby reducing the movement process of the forward and backward movement during operation.

[0014] Preferably, the injection gun is provided with a bottom plate, the support table is penetrated by a lead screw, the lead screw is rotatably connected with the bottom wall of the bottom plate, and the lead screw is threadedly connected with the support table.

[0015] Rotating the end of the lead screw away from the bottom plate makes the lead screw rotate to extend and retract on the support table, thereby driving the support table to move up and down, so that the height of the injection gun on the support table can be adjusted to adapt to the product processing requirements.

[0016] Preferably, the bottom plate is further provided with a guide rod below, the support table is provided with a guide cylinder, and the guide rod is slidably arranged in the guide cylinder.

[0017] The guide rod and the guide cylinder are beneficial to balance the injection gun, so that the injection gun is more stably arranged on the support table, and the multi-point support bottom plate is beneficial to reduce the stress of the lead screw.

[0018] Preferably, the injection gun is provided with a proximity sensor adjacent to the side wall.
