Description

Technical Field

[0001] This utility model relates to the field of casting production of upper vehicle valves, specifically to an iron shot molding device for casting production of upper vehicle valves. Background Technology

[0002] In the field of modern machinery manufacturing, the upper valve is a key component of vehicle braking systems and hydraulic systems, and its production quality directly affects the safety and reliability of vehicles. The surface treatment and shaping process of the upper valve housing are important factors that determine its performance. Good surface treatment can enhance the wear resistance, corrosion resistance, and adhesion to subsequent coatings of the housing.

[0003] Currently, traditional methods for surface treatment and shaping of the upper valve housing have many shortcomings. Some processes use manual grinding or simple mechanical processing, which is inefficient and makes it difficult to ensure the consistency of surface roughness, resulting in poor adhesion of subsequent coatings and easy peeling. Some processes that use shot blasting have complex equipment structures, are inconvenient to operate, and cannot achieve batch processing.

[0004] Therefore, developing an efficient, precise, and easy-to-operate iron shot molding device for casting production of the upper valve has become an urgent problem to be solved in the industry. Utility Model Content

[0005] The purpose of this invention is to provide an iron shot molding device for casting production of upper valves, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an iron shot molding device for casting production of upper valves, comprising an outer sand box, multiple molding boxes for molding iron shot for upper valve housings, and a support for placing the outer sand box. The outer sand box is provided with multiple partitions, which divide the outer sand box into multiple spaces for dry sand. The molding box is provided with a feed pipe for feeding iron shot, and the support is provided with a vibration component.

[0007] Preferably, the vibration assembly includes a slide rail mounted on a bracket, a vibration seat for fixing the outer sand box on the slide rail, a hydraulic cylinder controlled by a high-frequency reversing valve on the bracket, a positioning plate connected to the hydraulic cylinder on the vibration seat, and a locking assembly for fixing the outer sand box on the vibration seat.

[0008] Preferably, the locking assembly includes a support plate installed in the outer sand box, the vibration seat is provided with a placement groove that mates with the support plate, the support plate is provided with a plurality of pin holes, and the vibration seat is provided with a pin that mates with the pin holes.

[0009] Preferably, the feed pipe is provided with a cover plate.

[0010] Preferably, the top of the outer sand box is provided with a pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting an outer sand box for the molding box, the gap between the molding box and the outer shell provides space for the high-frequency movement of iron shot, enabling the iron shot to perform a shot blasting-like treatment on the exposed surface of the upper valve shell, forming an uneven, frosted surface, significantly increasing surface roughness and effectively improving the adhesion of subsequent coatings. Simultaneously, the hydraulic cylinder in the vibration assembly, in conjunction with a high-frequency reversing valve, achieves high-frequency reciprocating motion, driving the iron shot to impact the outer shell surface at high speed, causing micro-deformation of the outer shell surface, further roughening the surface, optimizing the molding quality, and ensuring that the upper valve shell has better performance and durability during subsequent processing and use.

[0013] 2. In this utility model, the outer sand box is divided into multiple spaces by partitions, which can hold multiple molding boxes at the same time, realize batch processing, and significantly improve production efficiency; dry sand fills the gap between the molding box and the outer sand box, and with the top pressure plate, it can not only stabilize the molding box, but also prevent dry sand from spilling, ensuring a clean production environment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] All electronic components in this application are controlled by an external controller.

[0024] Example 1

[0025] Please refer to Figure 1-7 As shown, this utility model provides a shot molding device for casting production of upper valves, including an outer sand box 1, multiple molding boxes 2 for molding shot for upper valve shells, and a support 3 for placing the outer sand box 1. The outer sand box 1 is provided with multiple partitions 4, which divide the outer sand box 1 into multiple spaces for dry sand. The molding boxes 2 are provided with feed pipes 5 for feeding shot. The support 3 is provided with a vibration component. The vibration component includes a slide rail 6 installed on the support 3, a vibration seat 7 for fixing the outer sand box 1 on the slide rail 6, a hydraulic cylinder 8 controlled by a high-frequency reversing valve on the support 3, a positioning plate 9 connected to the hydraulic cylinder 8 on the vibration seat 7, and a locking component for fixing the outer sand box 1 on the vibration seat 7.

[0026] After casting, the upper valve housing is placed in molding box 2. Molding box 2 adopts a split design, which facilitates the placement of the upper valve housing. The space between the internal space of molding box 2 and the upper valve housing is reserved for high-frequency movement of iron shot. The iron shot can perform a shot blasting-like treatment on the exposed surface of the upper valve housing, making the exposed surface uneven and frosted, which facilitates the adhesion of subsequent coatings. The feed pipe 5 is integrally formed on the top of molding box 2, which facilitates the placement of iron shot into the interior of molding box 2. The top of the outer sand box 1 is open, and there are multiple partitions 4. The partitions 4 are integrally formed inside the outer sand box 1, dividing the interior of the outer sand box 1 into multiple equal spaces. Molding box 2 can be placed in the equally divided spaces. The gap between the molding box 2 and the molded box 3 is filled with dry sand. The vibration component can make the molding box 2 vibrate, which facilitates the collision between the steel shot and the surface of the upper valve housing. The slide rail 6 is fixed to the bracket 3, and the vibration seat 7 is slidably connected to the slide rail 6. The hydraulic cylinder 8 can be purchased directly from the market. The positioning plate 9 is integrally formed at the bottom of the vibration seat 7. One end of the hydraulic cylinder 8 is fixed to the bracket 3, and the telescopic end of the hydraulic cylinder 8 is fixed to the positioning plate 9. The oil inlet and outlet of the hydraulic cylinder 8 is controlled by a high-frequency reversing valve (this is existing technology, so it will not be described in detail). The hydraulic cylinder 8 can reciprocate at high frequency, which can make the iron shot in the molding box 2 move at high speed. When the iron shot hits the surface of the upper valve housing, it will deform the surface of the upper valve housing, roughen the surface of the upper valve housing, and enhance the adhesion of the upper valve housing surface.

[0027] Specifically, the locking assembly includes a support plate 10 installed on the outer sand box 1, a placement groove 11 on the vibrating seat 7 that cooperates with the support plate 10, a plurality of pin holes 12 on the support plate 10, and a pin 13 on the vibrating seat 7 that cooperates with the pin holes 12. The support plate 10 is integrally formed on the bottom of the outer sand box 1, the placement groove 11 is opened on the vibrating seat to facilitate the positioning of the outer sand box 1, the pin holes 12 are opened on the support plate 10, and the pin 13 can be inserted into the pin holes 12 to easily fix the outer sand box 1.

[0028] The feed pipe 5 is equipped with a cover plate 14, which can prevent iron shot from splashing out during vibration.

[0029] Based on the above embodiments, specifically, the top of the outer sand box 1 is provided with a pressure plate 15. The pressure plate 15 is placed on the top of the outer sand box 1 to prevent dry sand from falling to the outside during vibration.

[0030] Working principle: In use, first, the upper valve housing to be processed is placed into the molding box 2. Then, a certain amount of iron shot is put into the molding box 2 through the feed pipe 5. Then, the opening of the feed pipe 5 is covered with the cover plate 14. After processing multiple molding boxes 2 in the above manner, the multiple molding boxes 2 are placed into the outer sand box 1, and the gap between the molding box 2 and the outer sand box 1 is filled with dry sand. Then, the pressure plate 15 is placed on the dry sand. Then, the outer sand box 1 is fixed to the vibrating seat 7, and the hydraulic cylinder 8 is used to drive the outer sand box 1 on the vibrating seat 7 to move back and forth. During this process, the iron shot will move at high frequency between the molding box 2 and the upper valve housing, which can impact the exposed surface of the upper valve housing, making the surface of the upper valve housing roughened. After molding is completed, the outer sand box 1 is removed, the molding box 2 is taken out of the outer sand box 1, and the upper valve housing can be taken out by opening the molding box 2.
