Description

Technical Field

[0001] This application relates to the field of preheating furnaces, and more particularly to mold preheating furnaces that facilitate the placement of molds. Background Technology

[0002] As a key piece of equipment used in industrial production for preheating molds, the core function of a mold preheating furnace is to improve mold processing efficiency and molding quality through uniform heating. Traditional mold preheating furnaces typically employ a single-cavity structure, requiring molds to be placed horizontally or vertically within the cavity using fixed supports or shelves. However, this structure suffers from several problems: firstly, the mold placement method is limited, resulting in low space utilization and an inability to accommodate the flexible placement requirements of molds of different sizes; secondly, mold handling is restricted, especially for large or heavy molds, necessitating repeated adjustments or the use of external equipment, leading to low operational efficiency; and thirdly, preheating uniformity is significantly affected by the cavity structure, easily resulting in uneven heating when molds are stacked. These problems make it difficult for traditional preheating furnaces to meet the demands of high-efficiency and high-flexibility production.

[0003] To improve the ease of mold placement, various improvement schemes have been proposed in the prior art. For example, a multi-layer horizontal placement preheating furnace, by setting up multi-layer retractable support frames within the cavity, allows molds to be pushed horizontally into placement slots of different levels, improving space utilization. Another common solution employs an adjustable-height support structure, with vertical guide rails and liftable trays within the cavity, allowing molds to be stacked vertically in layers, and their positions adjusted by raising and lowering the trays. Furthermore, some preheating furnaces utilize through-hole openings in the side walls of the cavity, allowing molds to be pushed horizontally into the cavity from one side, reducing the space occupied during operation. These technical solutions all aim to optimize the mold placement and retrieval process through layered, adjustable, or through-hole structures.

[0004] While the aforementioned existing technologies improve the convenience of mold placement to some extent, they still have significant drawbacks. First, although multi-layer horizontal placement allows for layered mold storage, the single-sided opening design restricts the mold retrieval path, requiring operators to frequently detour or adjust their positions, resulting in low efficiency, especially in dual-station collaborative operations. Second, in vertical stacking schemes, mold retrieval relies on a lifting mechanism, which is complex and lacks stability, easily leading to tipping risks when stacked too high. Furthermore, existing preheating furnaces mostly employ a single-cavity structure, unable to simultaneously accommodate horizontal and vertical placement modes, making it difficult to flexibly switch between different mold specifications and process requirements. More critically, the existing technologies have a single cavity opening direction, easily creating airflow dead zones after mold placement, leading to decreased preheating uniformity. Utility Model Content

[0005] In view of this, it is necessary to provide a mold preheating furnace that facilitates the placement of molds in order to solve the above problems.

[0006] Embodiments of this application provide a mold preheating furnace for convenient placement of molds, comprising:

[0007] The rack is placed on the ground;

[0008] A preheating chamber, located at the top of the frame, is used to heat the mold.

[0009] The preheating chamber includes a first preheating chamber and a second preheating chamber. The first preheating chamber and the second preheating chamber are arranged side by side on the same horizontal plane at the top of the frame, and the first preheating chamber and the second preheating chamber open toward opposite sides of the frame, respectively.

[0010] Several sets of placement openings are respectively provided on the side walls of the first preheating cavity and the second preheating cavity in the horizontal and vertical directions;

[0011] The horizontal placement port is provided through the frame from the opening side to the back side, and is used for horizontally pushing in or pulling out the mold; the vertical placement ports are distributed at intervals along the height direction of the preheating chamber, and are used for vertically stacking the mold.

[0012] In at least one embodiment of this application, the preheating furnace further includes a thermal reaction assembly in communication with the preheating chamber, the thermal reaction assembly being used to generate heat to preheat the mold.

[0013] In at least one embodiment of this application, the thermal reaction assembly includes a heat pipe assembly and a thermal reaction chamber disposed at the bottom end of the frame, the thermal reaction chamber being connected to the preheating chamber via the heat pipe assembly.

[0014] In at least one embodiment of this application, the heat pipe assembly includes a plurality of heat pipes uniformly distributed along a rectangle in the length direction of the frame.

[0015] In at least one embodiment of this application, a feed inlet is provided on one side of the thermal reaction chamber, and the feed inlet is used to add thermal reaction raw materials.

[0016] In at least one embodiment of this application, the cross-sectional profile of the placement opening is any one of a rectangle, a circle, or an ellipse.

[0017] In at least one embodiment of this application, an observation window is provided on the side of the frame facing the heat pipe assembly, and the observation window is used to detect the combustion status in the thermal reaction chamber.

[0018] In at least one embodiment of this application, the heat pipe is made of aluminum.

[0019] In at least one embodiment of this application, the frame is ceramic.

[0020] In at least one embodiment of this application, the outer peripheral surface of the frame is coated with a heat insulation layer.

[0021] The aforementioned mold preheating furnace, designed for convenient mold placement, significantly improves the ease of mold placement and space utilization by optimizing the structural layout of the preheating chamber and the design of the placement openings. Specifically, the first and second preheating chambers are arranged side-by-side on the same horizontal plane at the top of the frame and open towards both sides, allowing operators to simultaneously pick up and place molds from both sides of the frame, avoiding spatial conflicts during unilateral operations and shortening the mold movement path. Furthermore, the horizontally penetrating placement openings on the sidewalls of the chambers allow molds to be pushed in or pulled out horizontally from the opening side to the back side of the frame, simplifying the loading and unloading of large molds. The vertically spaced placement openings support vertical layered stacking of molds. Combined with the symmetrical layout of the two chambers, this achieves three-dimensional storage of molds while avoiding the stability problems caused by high concentration in traditional stacking.

[0037] Please see Figures 1-4 Embodiments of this application provide a mold preheating furnace 100 for convenient placement of molds, comprising:

[0038] Rack 1, placed on the ground;

[0039] The preheating chamber 2, located at the top of the frame 1, is used to heat the mold.

[0040] The preheating chamber 2 includes a first preheating chamber 3 and a second preheating chamber 4.

The vertical placement ports 5 are spaced along the height of the preheating chamber 2, supporting vertical layered stacking of molds. Combined with the symmetrical layout of the dual chambers, this achieves three-dimensional storage of molds and avoids the stability problems caused by high concentration in traditional stacking. In practical applications, operators can flexibly choose between horizontal or vertical placement modes according to mold size and process requirements. For example, horizontal pushing can be used when the mold size is large, while vertical stacking can be used when there are many molds, thus significantly improving the convenience of mold placement, space utilization, and preheating uniformity.
