Description

Technical Field

[0001] This utility model relates to the field of circuit breaker processing technology, and in particular to an integral molding equipment for a novel circuit breaker housing. Background Technology

[0002] In the fields of power systems, industrial power distribution, and civil power supply, circuit breakers are core equipment that ensures circuit safety and provides overload and short-circuit protection. Their housings play a crucial role in supporting internal electrical components, maintaining an insulating environment, and resisting external impacts and corrosion, which directly affects the safety, reliability, and service life of the equipment.

[0003] For a long time, the traditional circuit breaker housing has adopted a process of "welding the outer shell and inner frame together". However, the welding process has significant limitations: First, the heat input during welding can easily cause local deformation of the housing, making it difficult to accurately control the relative position of the inner frame and the outer shell. This, in turn, adversely affects the assembly accuracy of core components such as internal contacts and transmission mechanisms, increasing the complexity and difficulty of overall machine debugging. Second, welded joints are prone to forming stress concentration areas. When the equipment is subjected to vibration, impact, or temperature cycling conditions for a long time, there is a potential risk of cracking or detachment at the welded parts, weakening the long-term reliability of the housing structure. As the power sector continues to demand higher reliability, better assembly precision, and lower mass production costs for power distribution equipment, the drawbacks of traditional welded housings are becoming increasingly apparent, driving the industry to innovate the structural design and manufacturing process of circuit breaker housings. Under this trend, the research and application of one-piece molded circuit breaker housings has become inevitable. However, the surface of one-piece molded circuit breaker housings often has irregular protrusions, making it difficult to design the cavity for the extruded housing. At the same time, demolding often causes interference, greatly increasing the difficulty of demolding.

[0004] Therefore, this utility model proposes a novel integrated molding equipment for circuit breaker housings to solve the above problems. Utility Model Content

[0007] As a preferred embodiment of the integral molding equipment for the circuit breaker housing of the novel structure described in this utility model, the positioning module is an integral positioning box with a single-sided opening and a side-standing arrangement. The positioning module surrounds the molding contour of the circuit breaker housing to form a semi-closed cavity base. The positioning module includes a circumferential positioning plate group arranged continuously in the circumferential direction and a front positioning template fixed in the axial direction. A square groove is provided at the opening of the circumferential positioning plate assembly, and a portion of the internal moving module passes through the square groove to form a driving protrusion, which is connected to the first displacement structure.

[0008] As a preferred embodiment of the integral molding equipment for the circuit breaker housing of the novel structure described in this utility model, the internal moving module includes an upper built-in template and a lower built-in template that are opposite each other. A side template guide groove with a gradually narrowing front opening and a gradually widening rear opening is formed between the upper built-in template and the lower built-in template. Two built-in side templates that are opposite each other are installed in the side template guide groove. The outer side wall of the built-in side template is slidably adapted to the inner side wall of the side template guide groove. The outer side wall of the built-in side template is flush with the side wall of the upper built-in template. The upper built-in template, the lower built-in template, and the two built-in side templates enclose and form a box-type inner support cavity that runs through the front and back. The ends of the two built-in side templates that are away from the front fixed template are fixedly connected to the rear movable template.

[0009] As a preferred embodiment of the integral molding equipment for the circuit breaker housing of the novel structure described in this utility model, the box-type inner support cavity is provided with four sets of telescopic support structures arranged in a rectangular array at the four corners of the box-type inner support cavity. The telescopic support structure includes a telescopic vertical rod and a telescopic spring sleeved on the outside of the telescopic vertical rod. The two ends of the telescopic vertical rod are respectively hinged to the inner side wall of the upper inner template and the inner side wall of the lower inner template.

[0010] As a preferred embodiment of the integral molding equipment for the circuit breaker housing of the novel structure described in this utility model, the driving protrusion has a T-shaped cavity, and multiple telescopic rods slide within the T-shaped cavity, the multiple telescopic rods being connected to the first displacement structure.

[0011] As a preferred embodiment of the integral molding equipment for the circuit breaker housing of the novel structure described in this utility model, the first displacement structure includes a straight guide rail installed on the upper surface of the circumferential positioning plate group, a lead screw rotatably mounted inside the straight guide rail, a drive motor mounted at one end of the lead screw, the drive motor being fixed to the straight guide rail, a drive plate engaging with the surface of the straight guide rail, and a guide rail base threadedly connected to the surface of the lead screw, the guide rail base being fixed to the drive plate.

[0013] The beneficial effects of this utility model are as follows: By adopting an integrated positioning box with a single-sided opening, a semi-closed cavity base is formed by enclosing the shell molding contour. Combined with the design of the side template guide groove in the internal moving module, which has a gradually narrowing front opening and a gradually widening rear opening, and the built-in side template fixedly connected to the rear moving template, the built-in side template can slide and be pulled out along the guide groove under the unidirectional drive of the first and second displacement structures, releasing the lateral constraint on the side template guide groove. Furthermore, the four sets of telescopic support structures arranged in a rectangular array within the box-type internal support cavity release elastic potential energy through telescopic springs after the side template is pulled out, driving the upper and lower built-in templates to move in opposite directions vertically, causing their outer side walls to smoothly separate from the inner side walls of the inner frame plate. This completely avoids hard interference during the demolding process, achieving efficient and non-destructive integrated molding and demolding of the circuit breaker shell. This meets the power sector's requirements for higher reliability and better assembly precision in power distribution equipment, simplifies the cavity design and demolding process, reduces mass production costs, and provides strong support for the large-scale application of integrated circuit breaker shells.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Reference Figures 1-6 As shown, this embodiment provides an integral molding device for a novel circuit breaker housing, comprising: Refer to 1 and Figure 2As shown, the housing 01 includes an integrally formed inner frame plate 012 and an outer shell plate 011. The lower surface of the inner frame plate 012 has an array of multiple mounting slots 0121. The mounting slots 0121 are mounted on the lower surface of the inner frame plate 012 to form protrusions, which makes it difficult for the extrusion module 04 of the extruded inner frame plate 012 and outer shell plate 011 to be removed from the surface of the inner frame plate 012 and outer shell plate 011, thus forming interference.

[0021] Reference Figure 3 and Figure 4 As shown, the integral molding equipment includes an extrusion module 04 for forming an integrally molded inner frame plate 012 and outer shell plate 011, a first displacement structure 02 disposed on the upper end face of the extrusion module 04, and a second displacement structure 03 disposed on the lower end face of the extrusion module 04. The extrusion module 04 includes a positioning module, a rear moving template 042, and an inner moving module. An extrusion cavity for extruding the inner frame plate 012 and outer shell plate 011 is formed between the positioning module, the rear moving template 042, and the inner moving module. The first displacement structure 02 is connected to the inner moving module, and the second displacement structure 03 is connected to the rear moving template 042. The first displacement structure 02 and the second displacement structure 03 drive the inner moving module and the rear moving template 042 to move in the same direction to disengage from the positioning module.

[0022] Reference Figure 3 and Figure 4 As shown, the positioning module is an integrated positioning box with a single-sided opening and a side-standing arrangement. The positioning module is formed by enclosing a semi-closed cavity base along the molding contour of the circuit breaker housing 01. The positioning module includes a circumferential positioning plate group arranged continuously in the circumferential direction and a front positioning template 0411 fixed in the axial direction. The circumferential positioning plate assembly includes an upper fixed template 0413 and a lower fixed template 0412 arranged laterally, and two side fixed templates arranged symmetrically in the longitudinal direction. The upper positioning plate, the lower positioning plate and the two side positioning plates are connected end to end to form a closed circumferential enclosure structure. Its inner side wall is adapted to the outer circumferential contour of the circuit breaker housing 01. The front fixed template 0411 is vertically fixed to one axial end of the circumferential positioning plate assembly and is opposite to the rear moving template 042. Its inner end face is fitted to the front forming surface of the circuit breaker housing 01 to form an axial positioning reference. A square groove 0414 is provided at the opening of the circumferential positioning plate group, i.e., the upper fixed template 0413. Part of the inner moving module passes through the square groove 0414 to form a driving protrusion 0432, which is connected to the first displacement structure 02.

[0023] Reference Figure 4 and Figure 5As shown, the inner moving module is a box-shaped structure that runs through the front and back. Its outer wall contour is adapted to the inner side wall contour of the positioning module. The two enclose each other to form an extrusion cavity for forming the inner frame plate 012 and the outer shell plate 011. The inner moving module includes an upper inner template 0431 and a lower inner template 0436 that are opposite each other. A side template guide groove with a gradually narrowing front opening and a gradually widening rear opening is formed between the upper inner template 0431 and the lower inner template 0436. Two inner side templates 0433 that are opposite each other are installed in the side template guide groove. The outer side wall of the inner side template 0433 is slidably adapted to the inner side wall of the side template guide groove. The outer side wall of the inner side template 0433 is flush with the side wall of the upper inner template 0431. Its outer side wall simultaneously forms part of the outer wall of the inner moving module, and together with the outer side wall of the upper inner template 0431 and the outer side wall of the lower inner template 0436, they form a continuous cavity forming surface. The upper built-in template 0431, the lower built-in template 0436, and the two built-in side templates 0433 enclose a box-type inner support cavity that runs through the front and rear. The ends of the two built-in side templates 0433 that are away from the front fixed template 0411 are fixedly connected to the rear moving template 042 and move synchronously with the rear end of the rear moving template 042. When the first displacement structure 02 drives the inner moving module and the second displacement structure 03 drives the rear moving template 042 to move in the same direction, the built-in side templates 0433 slide along the inner wall of the side guide cavity, causing the outer wall of the inner moving module to gradually separate from the inner wall of the positioning module, thereby realizing the separation of the extrusion cavity from the inner frame plate 012 and the outer shell plate 011 after molding.

[0024] Reference Figure 4 and Figure 5 As shown, four sets of telescopic support structures are arranged inside the box-type inner support cavity. The four sets of telescopic support structures are arranged in a rectangular array at the four corners of the box-type inner support cavity and are symmetrically distributed on the inner side of the two built-in side templates 0433. The telescopic support structure includes a telescopic vertical rod 0434 and a telescopic spring 0435 sleeved on the outside of the telescopic vertical rod 0434. The two ends of the telescopic vertical rod 0434 are respectively hinged to the inner side wall of the upper built-in template 0431 and the inner side wall of the lower built-in template 0436. The two ends of the telescopic spring 0435 are respectively abutted between the upper built-in template 0431 and the lower built-in template 0436. Under normal conditions, it is in a pre-stretched state to provide outward tension, so that the outer side walls of the upper built-in template 0431 and the lower built-in template 0436 are tightly fitted with the inner side wall of the inner frame plate 012. When the built-in side template 0433 is removed from the side template guide groove, the lateral constraint of the built-in side template 0433 on the side template guide groove is reduced. The telescopic spring 0435 releases elastic potential energy and drives the telescopic vertical rod 0434 to contract axially, thereby pulling the upper built-in template 0431 and the lower built-in template 0436 to move towards each other in the vertical direction, so that their outer side wall gradually separates from the inner side wall of the inner frame plate 012, avoiding hard interference between the inner moving module and the formed inner frame plate 012.

[0025] Reference Figure 5 As shown, the driving protrusion 0432 has a T-shaped cavity 04321, and multiple telescopic rods 0241 slide inside the T-shaped cavity 04321. The multiple telescopic rods 0241 are connected to the first displacement structure 02, so that the first displacement structure 02 can drive the internal moving module to move without interfering with the relative movement of the upper built-in template 0431 and the lower built-in template 0436.

[0026] Reference Figure 3 and Figure 4 As shown, the first displacement structure 02 includes a straight guide rail 021 mounted on the upper surface of the circumferential positioning plate assembly. A lead screw 023 is rotatably mounted inside the straight guide rail 021. A drive motor 022 is mounted on one end of the lead screw 023. The drive motor 022 is fixed to the straight guide rail 021. A drive plate 025 is engaged with the surface of the straight guide rail 021. A guide rail base 024 is threadedly connected to the surface of the lead screw 023. The guide rail base 024 is fixed to the drive plate 025.

[0027] Reference Figure 4 and Figure 5 As shown, the lower surface of the rear moving template 042 is provided with a connecting plate 0421. The rear moving template 042 is connected to the second displacement structure 03 through the connecting plate 0421. The second displacement structure 03 has the same structure as the first displacement structure 02.

[0028] Working principle: In the initial state of the equipment, the upper fixed template 0413, lower fixed template 0412, side fixed templates and front fixed template 0411 of the positioning module form a semi-closed cavity base. The upper internal template 0431 of the internal moving module is in contact with the inner side wall of the upper fixed template 0413. The positioning module, rear moving template 042 and internal moving module together form a complete extrusion cavity. At this time, the four sets of telescopic support structures in the box-type inner support cavity of the internal moving module are in a pre-tensioned state. The tension of the telescopic spring 0435 makes the outer side walls of the upper internal template 0431 and lower internal template 0436 fit tightly with the forming position of the inner frame plate 012. The internal side template 0433 maintains lateral support to the side template guide groove through the fixed connection with the rear moving template 042, ensuring the contour accuracy of the extrusion cavity and providing a stable forming space for the extrusion forming of the inner frame plate 012 and the outer shell plate 011.

[0029] The surface of the front fixed template 0411 is provided with injection holes. The molding material is injected or pressed into the extrusion cavity through the injection holes. Under the axial constraints of the positioning module inner wall constraining the outer periphery of the outer shell plate 011, the inner wall of the inner moving module constraining the inner side of the inner frame plate 012, and the front fixed template 0411 and the rear moving template 042, the material is integrally formed into an inner frame plate 012 and an outer shell plate 011 with a protrusion on the lower surface of the inner frame plate 012 with an installation groove cylinder 0121.

[0030] After the inner frame plate 012 and outer shell plate 011 have cooled and formed, the first displacement structure 02 and the second displacement structure 03 are activated synchronously, driving the inner moving module and the rear moving template 042 to move in the same direction away from the front fixed template 0411. The rear moving template 042 moves backward under the drive of the second displacement structure 03, and at the same time drives the two built-in side templates 0433 fixed thereto to move backward synchronously. The built-in side templates 0433 slide along the inner wall of the side template guide groove and gradually pull away from the guide groove, releasing the lateral constraint on the side template guide groove. As the built-in side template 0433 is removed, the telescopic spring 0435 of the telescopic support structure releases the elastic potential energy of the pre-stretched state, causing the telescopic vertical rod 0434 to contract axially, thereby pulling the upper built-in template 0431 and the lower built-in template 0436 to move towards each other in the vertical direction, so that their outer side wall and the inner side wall of the inner frame plate 012, especially the corresponding position of the mounting groove cylinder 0121, gradually separate, avoiding hard interference between the inner moving module and the protruding structure of the inner frame plate 012; At the same time, driven by the first displacement structure 02, the internal moving module slides synchronously backward along the square groove 0414 of the upper fixed template 0413 through the driving protrusion 0432. Its outer wall gradually separates from the inner side wall of the positioning module. With the opposite contraction of the upper and lower built-in templates 0436, the internal moving module and the inner frame plate 012 are completely separated. Finally, the inner moving module and the rear moving template 042 completely detach from the positioning module during their co-directional movement. The formed inner frame plate 012 and outer shell plate 011 are then carried out together with the inner moving module, completing the demolding process.

[0031] Through the unidirectional driving of the first displacement structure 02 and the second displacement structure 03 and the adaptive contraction linkage of the telescopic support structure, the equipment effectively solves the demolding interference problem caused by the protrusion of the inner frame plate 012 mounting groove cylinder 0121, and realizes efficient and non-destructive integrated molding and demolding of the circuit breaker housing 01.

[0032] This application abandons the traditional process of "welding the outer shell and inner frame together". By forming a complete extrusion cavity through the positioning module, the inner moving module and the rear moving template 042, the inner frame plate 012 and the outer shell plate 011 are integrally formed. This fundamentally avoids the problem of local deformation of the shell 01 caused by the heat input of the welding process, and greatly improves the relative positional accuracy of the inner frame and the outer shell. This provides a reliable guarantee for the precise assembly of core components such as internal contacts and transmission mechanisms, and reduces the complexity and difficulty of overall machine debugging. At the same time, the integrally formed structure eliminates the stress concentration area of ​​the welded joint, significantly enhances the overall rigidity and stability of the shell 01 structure, and effectively avoids the potential risk of cracking and desoldering of the welded parts under long-term vibration, impact or temperature cycling conditions, thus extending the service life and operational reliability of the circuit breaker shell 01.

[0033] To address the challenges in cavity design and demolding interference caused by the protrusion of the mounting groove 0121 on the lower surface of the inner frame plate 012 in the integrated molded circuit breaker housing 01, the equipment employs an integrated positioning box with a single-sided opening to form a semi-closed cavity base along the molding contour of the housing 01. This is complemented by a side template guide groove design in the internal moving module, with a gradually narrowing front opening and a gradually widening rear opening, and an internal side template 0433 fixedly connected to the rear moving template 042. Under the unidirectional drive of the first displacement structure 02 and the second displacement structure 03, the internal side template 0433 can slide and be removed along the guide groove, releasing the lateral constraint on the side template guide groove. The box-type internal support cavity contains four sets of telescopic support structures arranged in a rectangular array. After the side template is removed, the elastic potential energy is released by the telescopic spring 0435, which drives the upper and lower internal templates 0436 to move towards each other in the vertical direction. This allows the outer side wall to separate smoothly from the inner side wall of the inner frame plate 012, completely avoiding hard interference during the demolding process. This achieves efficient and non-destructive one-piece molding and demolding of the circuit breaker housing 01, meeting the power industry's requirements for higher reliability and better assembly precision of power distribution equipment. It also simplifies the cavity design and demolding process, reduces mass production costs, and provides strong support for the large-scale application of the one-piece molded circuit breaker housing 01.
