Description
Technical Field
[0001] This utility model relates to the field of injection mold blank technology, and in particular to an injection mold blank for processing the inner panel of a vertical air conditioner. Background Technology
[0002] Injection mold blanks, also known as mold bases, are the skeleton of the entire mold. The structure of the mold blank must be taken into account when manufacturing all mold parts. Injection mold blanks play a crucial role in injection molds. Selecting appropriate materials, adopting reasonable manufacturing processes, and regular maintenance are key factors in ensuring the quality and service life of injection molds.
[0003] However, traditional injection mold blanks for processing the inner panel of vertical air conditioners have a simple structure. During the injection process, heat is easily conducted excessively on the mold blank, which not only affects the temperature control of the mold during the injection process, but also affects the heat dissipation after processing. Utility Model Content
[0004] This utility model discloses an injection mold blank for processing the inner panel of a vertical air conditioner, aiming to solve the technical problem that traditional injection mold blanks for processing the inner panel of a vertical air conditioner have a simple structure and the heat is easily excessively conducted on the mold blank during the injection process, which not only affects the temperature control of the mold during the injection process, but also affects the heat dissipation after processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A molding blank for processing the inner panel of a vertical air conditioner includes a plate A and a plate B. The top of plate A is provided with a runner plate, and the bottom outer wall of plate B is provided with a mold foot. The mold blank further includes: a heat insulation mechanism: the heat insulation mechanism includes a top sealing plate disposed on the top of the runner plate, a bottom sealing plate disposed on the bottom outer wall of the mold foot, and outer heat insulation plates disposed on the top outer wall of the top sealing plate and the bottom outer wall of the bottom sealing plate; a male mold core disposed on plate B, and inner heat insulation plates evenly distributed on the bottom inner wall of the male mold core; and a limiting and guiding mechanism: the limiting and guiding mechanism is disposed between plate A and plate B.
[0007] In this solution, the external heat insulation plates installed on the bottom and top sealing plates effectively insulate the mold blank and the injection molding machine, preventing excessive heat transfer between the upper and lower sealing plates and other parts of the mold. This helps maintain the stability of the mold temperature and reduces dimensional fluctuations and deformation of the product caused by temperature changes during the injection molding process. In addition, the internal heat insulation plates effectively reduce heat transfer from the mold to the injection molding machine or the outside environment, thereby accelerating the mold's heating rate and improving production efficiency.

[0009] By guiding the square guide pillars and square guide sleeves, and limiting the position of the limiting blocks and limiting grooves, the pressure on other internal guide pillars and guide sleeves is relieved. At the same time, the stability of the connection between plate A and plate B during the injection molding process is ensured, allowing the injection molding process to proceed stably.

Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0018] The injection mold blank disclosed in this utility model for processing the inner panel of a vertical air conditioner is mainly used in traditional injection mold blanks for processing the inner panel of a vertical air conditioner. When in use, the structure is simple, and the heat is easily excessively conducted on the mold blank during the injection process. This not only affects the temperature control of the mold during the injection process, but also affects the heat dissipation after processing.
[0019] Reference Figure 1 , Figure 3 and Figure 5 A vertical air conditioner inner panel processing injection mold blank includes an A plate 2 and a B plate 3. The top of the A plate 2 is provided with a runner plate, and the bottom outer wall of the B plate 3 is provided with a mold foot 4. It also includes: a heat insulation mechanism: the heat insulation mechanism includes a top sealing plate 1 provided on the top of the runner plate, a bottom sealing plate 5 provided on the bottom outer wall of the mold foot 4, and an outer heat insulation plate 7 provided on the top outer wall of the top sealing plate 1 and the bottom outer wall of the bottom sealing plate 5.

[0020] Specifically, the external heat insulation plates 7 installed on the bottom sealing plate 5 and the top sealing plate 1 can effectively insulate the mold blank and the injection molding machine, preventing excessive heat transfer between the upper sealing plate, the lower sealing plate and other parts of the mold, which helps to maintain the stability of the mold temperature. During the injection molding process, it can also reduce the dimensional fluctuations and deformation of the product caused by temperature changes. In addition, the internal heat insulation plate 11 can effectively reduce the heat transfer from the mold to the injection molding machine or the outside world, thereby accelerating the heating rate of the mold and improving production efficiency.
[0021] The outer heat insulation board 7 is made of brown bakelite board, and the inner heat insulation board 11 is made of glass fiber and silicate adhesive.
[0022] It should be noted that brown bakelite board is a synthetic paperboard made by impregnating insulating paper with phenolic resin, followed by baking and hot pressing.

[0024] Specifically, the guidance of the square guide post 15 and the square guide sleeve, as well as the limiting block 9 and the limiting groove, alleviate the pressure on other internal guide posts and guide sleeves. At the same time, it ensures the stability of the connection between plate A 2 and plate B 3 during the injection molding process, so that the injection molding process can proceed stably.
[0025] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, a bottom pin plate 13 is connected to the top outer wall of the bottom sealing plate 5. Several square irons are provided around the bottom pin plate 13. The mold foot 4 is composed of the bottom pin plate 13 and several square irons.

The face pin plate 14 is sleeved on the outer wall of the return pin 12. A filling port 6 is provided on the top sealing plate 1.
[0026] Among them, the inner wall of plate A2 is provided with a female mold core 8, and the positions of the female mold core 8 and the male mold core 10 are opposite to each other.
[0027] Working principle: When using, the male mold core 10 and female mold core 8 inside the mold blank need to be precisely machined to ensure that the dimensions are strictly consistent with the requirements. After assembly, check that the guide pillars and guide sleeves (only the square guide pillar 15 is shown in the attached diagram of this solution) are pressed firmly and reliably. Check whether the sliding of plate A2 along the internal guide pillar is smooth and without tightness. Lubrication should be ensured between the sliding surfaces of plate A2 and plate B3. After preparation, start to use the injection molding machine with the mold blank for trial molding. After the trial molding is successful, it can be put into production and processing.
