Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for air conditioner production. Background Technology
[0002] Most air conditioner parts are manufactured using injection molding, including air conditioner brackets. Air conditioner brackets are important supporting structures with high strength requirements. Therefore, in the injection molding production of air conditioner brackets, glass fiber material is often added to the injection melt to increase structural strength. However, due to the high hardness of glass fiber, it can easily aggravate mold core wear during injection molding. Mold core wear can lead to changes in mold cavity dimensions, which in turn affects the product dimensions. As a supporting structure, the dimensional accuracy of air conditioner brackets may affect installation and load-bearing performance. Therefore, in order to ensure product quality, the mold core needs to be replaced regularly.
[0003] Currently, the installation method for mold cores is usually to fix the mold core in the mold core mounting slot with screws. This installation method requires workers to align the screw holes on the mold core with the screw holes in the mold core mounting slot and tighten each screw. This not only increases the workload of workers, but also makes the installation process complicated and affects the installation efficiency. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an injection mold for air conditioner production, so as to solve the problem of low installation efficiency of the current mold core.
[0005] The technical solution adopted in this utility model is as follows:
[0006] An injection mold for air conditioner production includes a mounting base. The upper side of the mounting base has a mounting groove for mounting a mold core. The bottom of the mounting groove has several positioning elements for positioning the mold core. The bottom of the mold core has several positioning grooves that mate with the positioning elements. The mold core also includes a limiting assembly for locking the mold core. The limiting assembly includes several sliding rods slidably connected to the side wall of the mounting groove. Each sliding rod has a connecting rod at its end near the mold core. The side wall of the mold core has slots for engaging the connecting rods. When the positioning grooves of the mold core mate with the corresponding positioning elements, the connecting rods can be driven to extend into the slots for limiting.
[0007] The working principle is as follows:
[0008] When installing the mold core, place the mold core into the installation slot and align the positioning slot at the bottom of the mold core with the corresponding positioning component to determine the installation position of the mold core. Then, through the cooperation of the positioning slot and the positioning component, the sliding rod and the plug-in rod move towards the mold core. After the plug-in rod is inserted into the corresponding slot on the side wall of the mold core, the mold core is fixed on the mounting base.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] By cooperating with the positioning slot and the positioning component, the mold core can be positioned. At the same time, the positioning slot and the positioning component can drive the plug rod to extend into the slot on the side wall of the mold core to achieve automatic limit. No additional operation is required from the staff, which reduces the workload and the current turning action, and can effectively improve the installation efficiency.
[0011] In a preferred embodiment of this utility model, the side wall of the mounting base is provided with a horizontal sliding groove that cooperates with the sliding rod. The mounting base is also provided with a mounting cavity that communicates with the sliding groove. A lifting plate is provided in the mounting cavity. An inclined groove is opened on the upper part of the lifting plate. The end of the sliding rod away from the plug rod passes through the mounting cavity and is fixed with a connecting rod. The connecting rod passes through the inclined groove.
[0012] Beneficial effects: In this solution, the connecting rod cooperates with the inclined groove. When the lifting plate is raised or lowered, the connecting rod slides in the inclined groove, thereby driving the sliding rod and the plug rod to slide horizontally. This structure has a simple transmission method and low structural cost.
[0013] In a preferred embodiment of this utility model, the lower end of the lifting plate is connected to a driving assembly, the driving assembly includes a vertically arranged cylinder, the free end of the cylinder piston rod is fixed with a connecting plate, the connecting plate is located in the mounting cavity and fixed to the lower end of the lifting plate, and the upper end of the positioning member is provided with a pressure switch, the pressure switch is used to control the operation of the cylinder.
[0014] Beneficial effects: When the positioning groove of the mold core is aligned with the positioning component, the weight of the mold core applies pressure to the pressure switch, which activates the cylinder, causing the cylinder to rise or fall, driving the connecting plate and the lifting plate to move synchronously. The lifting plate then drives the plug rod to insert into the slot of the mold core, thus achieving automatic limit.
[0015] In a preferred embodiment of this utility model, the positioning element is a cylinder protruding from the bottom surface of the mounting groove, and the number of the positioning elements is greater than or equal to two.
[0016] Beneficial effects: When the positioning element is a cylinder and the number of positioning elements is greater than or equal to two, the center of the positioning element is regarded as a point. A straight line is determined based on the two points. The horizontal positioning of the mold core can be achieved through two or more points, thereby realizing the positioning of the mold core.
[0017] In a preferred embodiment of this utility model, the positioning element is a rectangle protruding from the bottom surface of the mounting groove, and the number of the positioning elements is greater than or equal to one.
[0018] Beneficial effects: When the positioning element is rectangular and the number of positioning elements is greater than or equal to one, the four sides of the rectangle can restrict the horizontal rotation of the mold core, and the center of the rectangle can be used as the horizontal positioning point to realize the positioning of the mold core.
[0019] In a preferred embodiment of this utility model, the cross-section of the slide rod is larger than the cross-section of the plug rod, and a shoulder is formed at the connection position of the slide rod and the plug rod, and the shoulder abuts against the side wall of the mold core.
[0020] Beneficial effect: After the insertion rod extends into the slot, the slide bar can be pushed forward to make the shoulder further press against the side wall of the mold core, thus improving the fixing effect of the mold core. Attached Figure Description

Detailed Implementation
[0025] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0027] See Figure 1 and Figure 2As shown, this embodiment discloses an injection mold for air conditioner production, including a mounting base 1. The upper side of the mounting base 1 has a mounting groove 11 for mounting a mold core 2. The bottom of the mounting groove 11 has several positioning elements 3 for positioning the mold core 2. In this embodiment, the positioning elements 3 are cylinders protruding from the bottom surface of the mounting groove 11, and there are four positioning elements 3 evenly distributed on the bottom surface of the mounting groove 11. In other embodiments, the positioning elements 3 are rectangles protruding from the bottom surface of the mounting groove 11. The bottom of the mold core 2 has four positioning grooves that mate with the four positioning elements 3. When installing the mold core 2, the mold core 2 is placed into the mounting groove 11, and the positioning grooves at the bottom of the mold core 2 are aligned with the corresponding positioning elements 3 to achieve positioning of the mold core 2.
[0028] See Figure 3 As shown, it also includes a limiting component 4 for locking the mold core 2. The limiting component 4 includes several sliding rods 41 slidably connected to the side wall of the mounting groove 11. In this embodiment, two sliding rods 41 are respectively provided on opposite side walls of the mounting groove 11. In other embodiments, at least one sliding rod 41 can be provided on each of the four side walls of the mounting groove 11. Each sliding rod 41 has an integrally formed insertion rod 411 at one end near the mold core 2, and the side wall of the mold core 2 has four slots for cooperating with the four insertion rods 411.
[0029] See Figure 3 As shown, the side wall of the mounting base 1 is provided with a horizontal sliding groove 13 that mates with the sliding rod 41. The mounting base 1 is also provided with a mounting cavity 12 that communicates with the sliding groove 13. A lifting plate 61 is provided in the mounting cavity 12. An inclined groove 611 is opened on the upper part of the lifting plate 61. In this embodiment, the higher end of the inclined groove 611 is close to the mounting groove 11. The end of the sliding rod 41 away from the plug rod 411 passes through the mounting cavity 12 and is fixed with a connecting rod 42. The connecting rod 42 passes through the inclined groove 611. In use, when the lifting plate 61 descends, the connecting rod 42 slides in the inclined groove 611, thereby driving the sliding rod 41 and the plug rod 411 to slide horizontally inward, and the plug rod 411 extends into the slot; conversely, when the lifting plate 61 rises, the connecting rod 42 drives the sliding rod 41 and the plug rod 411 to slide horizontally outward, and the plug rod 411 exits the slot.
[0030] See Figure 2As shown, the lower end of the lifting plate 61 is connected to a drive assembly, which includes a vertically arranged cylinder 5. The free end of the piston rod of the cylinder 5 passes through the mounting cavity 12 and is fixed to a connecting plate 6. The lower end of the lifting plate 61 is fixed on the connecting plate 6. A pressure switch 31 is installed on the upper end of the positioning component 3. The pressure switch 31 is used to control the operation of the cylinder 5. When the positioning groove of the mold core 2 is aligned with the positioning component 3, the weight of the mold core 2 applies pressure to the pressure switch 31, starts the cylinder 5, and controls the piston rod to descend, thereby driving the connecting plate 6 and the lifting plate 61 to descend. The lifting plate 61 then drives the sliding rod 41 and the insertion rod 411 to move. The insertion rod 411 is inserted into the slot of the mold core 2, thus realizing automatic limit.
[0031] Further, see Figure 3 As shown, the cross-section of the slide rod 41 is larger than that of the insertion rod 411, and a shoulder 412 is formed at the connection position of the slide rod 41 and the insertion rod 411. After the insertion rod 411 extends into the slot, the slide rod 41 continues to advance, so that the shoulder 412 abuts against the side wall of the mold core 2 to further fix the mold core 2.
[0032] The usage method of this embodiment is as follows:
[0033] When installing the mold core 2, place the mold core 2 into the installation slot 11 and align the positioning slot at the bottom of the mold core 2 with the corresponding positioning part 3. At this time, the mold core 2 is positioned and the pressure switch 31 is triggered, the cylinder 5 is started, the lifting plate 61 is lowered, thereby driving the insertion rod 411 to move inward and insert it into the slot of the mold core 2. After the insertion rod 411 is inserted into the slot, the insertion rod 411 continues to advance until the shoulder 412 abuts against the side wall of the mold core 2, thereby fixing the mold core 2.
[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
