Description

Technical Field

[0001] This utility model relates to the field of automotive heater rod rear cover manufacturing technology, and in particular to a die-casting mold for processing heater rod rear covers. Background Technology

[0002] A heating rod is a commonly used auxiliary heating device in automobiles. The outer casing of a heating rod consists of a front cover and a rear cover. For example... Figure 6-7 As shown, the heating rod back cover includes a back cover body 19, with a circular through hole 20 on each side of the back cover body 19. A docking post 21 is provided on the upper end of the back cover body 19 inside each circular through hole 20. A circular hole 22 is opened in the middle of the upper end of the docking post 21. The docking post 21 and the circular hole 22 are relatively difficult to demold. The inner wall of the circular through hole 20 has an inward recessed area 23 on the side close to the adjacent docking post 21. The recessed area 23 cannot be demolded in the normal demolding direction and needs to be filled. The filled recessed area 23 needs to be processed again later, which can easily cause shrinkage cavities and affect product quality. Summary of the Invention

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0018] The present invention relates to a die-casting mold for processing the rear cover of a heating rod, such as... Figure 1-7 As shown, the system includes an upper mold frame 1 and a lower mold frame 4. An upper mold core 2 and a lower mold core 3, stacked vertically, are installed between the upper mold frame 1 and the lower mold frame 4. At least one mold cavity is provided between the upper mold core 2 and the lower mold core 3. A insert 10 is fixedly installed on both sides of the lower end of each upper mold core 2 inside each mold cavity. Two inserts 10 located in the same mold cavity are arranged symmetrically. A docking groove 16 is provided at the bottom of each insert 10. A sliding hole rod 11 is installed in each insert 10, with its lower end inserted into the docking groove 16. A corresponding connecting rod 11 is installed on the upper part of the upper mold frame 1. The small hydraulic cylinder 12 is connected. The upper end of the lower mold core 3 is equipped with an inclined sliding rod 9 on both sides inside each mold cavity. The two inclined sliding rods 9 in the same mold cavity are symmetrically arranged, and the distance between the two inclined sliding rods 9 gradually increases from bottom to top. The inner side of the upper end of the inclined sliding rod 9 is provided with an inner buckle 13. The lower end of the lower mold frame 4 is equipped with a mold foot 6 on each side. The top plate assembly 7 is installed between the two mold feet 6. The top plate assembly 7 is equipped with a push rod 5 that is vertically inserted into the mold cavity and a drive seat 8 connected to the inclined sliding rod 9. The lower end of the inclined sliding rod 9 slides laterally along the drive seat 8.

[0019] The lower end of the inclined top slide rod 9 is an inverted T-shaped sliding part 15. The upper end of the drive seat 8 is provided with a horizontal groove 14 that cooperates with the sliding part 15. The two ends of the groove 14 pass through the side walls on both sides of the drive seat 8. Through the cooperation of the sliding part 15 and the groove 14, the lower end of the inclined top slide rod 9 can slide back and forth horizontally along the drive seat 8.

[0020] The lower mold core 3 is provided with a positioning boss 17 at each of the four corners of its upper end, and the upper mold core 2 is provided with a positioning groove 18 at its lower end that corresponds to the positioning boss 17. The positioning boss 17 and the positioning groove 18 cooperate to ensure the accuracy of the docking between the upper mold core 2 and the lower mold core 3, thereby ensuring the quality of the product.

[0021] Two inclined slide rods 9 and a drive seat 8 form an inclined ejector device. Two small hydraulic cylinders 12, two hole rods 11, and two inserts 10 form a mating column forming device. This die-casting mold is a double-cavity mold with two cavities arranged side by side. Each cavity is equipped with an inclined ejector device and a mating column forming device. When it is necessary to produce the heating rod back cover, the upper mold frame 1 and upper mold core 2 are controlled to close with the lower mold frame 4 and lower mold core 3. The small hydraulic cylinders 12 are activated, and the small hydraulic cylinders 12 control the hole rods 11 to slide downward so that the lower end of the hole rods 11 is inserted into the mating column groove 16 at the bottom of the insert 10. The groove 16 is used to assist in forming the docking post 21, the lower end of the hole rod 11 is used to assist in forming the circular hole 22, and the inner buckle 13 is used to assist in forming the recessed area 23. Then, molten metal is injected into the mold cavity. After the product is formed, the hole rod 11 is controlled to slide upward by controlling the small oil cylinder 12 so that the hole rod 11 is separated from the formed circular hole 22. Then the mold is opened, the upper mold frame 1 and the upper mold core 2 move upward, and finally the top plate assembly 7 controls the ejector rod 5 and the inclined ejector device to move upward. The inner buckles 13 of the two inclined ejector slide rods 9 move away from each other, so that the inner buckles 13 are separated from the recessed area 23. At the same time, the ejector rod 5 ejects the product.

[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0023] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0024] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0025] The above provides a detailed description of a die-casting mold for processing a heating rod back cover. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
