Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a secondary core-pulling component of a refrigerator product mold. Background Art

[0002] like Figure 1 The refrigerator drain pipe product 3 shown in the figure adopts independent core-pulling mechanisms in the design to realize the core-pulling forming components of the vertical side structure 301 and the bottom side structure 302 due to the different product structural surfaces. However, since the bottom side structure 302 is relatively complex and has complex lateral structures such as deep reinforcing ribs, the core-pulling distance is relatively long and a certain core-pulling force is required. Therefore, for the core-pulling of the bottom side structure 302, an inclined guide column core-pulling structure 4 with inclined guide columns is selected. Since the inclined guide columns need to be fixed on the front mold core, they will move upward with the front mold core when the mold is opened. The side forming structure of the vertical side structure 301 requires side straight-out core pulling. The vertical side structure 301 is above the side core-pulling structure. There is not enough space in the mold to set two side core-pulling structures. There is mutual interference between the core-pulling structures when the mold is opened, which makes the product unable to be demolded. Utility Model Content

[0027] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0028] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0029] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0030] The embodiment of the present utility model provides a secondary core pulling component of a refrigerator product mold, such as Figure 1-10 As shown, it includes a front mold core 1, and the front mold core 1 is provided with a lateral secondary core pulling assembly 2 for pulling the core of the vertical side structure 301. The lateral secondary core pulling assembly 2 includes a plurality of lateral core pulling sliders 210 passing through the front mold core 1, a steering slider 220 slidingly connected with the lateral core pulling slider 210, a steering seat 230 arranged on one side of the front mold core 1 and slidingly connected with the steering slider 220, a driving structure 240 fixed on one side of the front mold core 1 and slidingly connected with the steering slider 220, and a limiting structure 250 for controlling the core pulling distance of the lateral core pulling slider 210, wherein the driving structure 240 is used to drive the steering slider 220 to slide in the steering seat 230, thereby driving the lateral core pulling slider 210 to move and pull the core.

[0031] The lateral core pulling slider 210 is used to form the vertical side structure 301. In order not to occupy the internal space of the mold, the structure for driving the lateral core pulling slider 210 is set outside the mold. The lateral core pulling slider 210 passes through the front mold core 1 to reach the outside of the mold and continues to cooperate with other structures, further compacting the mold structure and saving costs. The driving structure 240 provides the core pulling force. In order to make the mold more compact, the driving structure 240 is installed close to the side of the mold. The driving structure 240 can be installed and fixed vertically, horizontally or obliquely according to actual conditions. The steering slider 220 serves as a transfer station for the driving structure 240 and the lateral core pulling slider 210. It not only realizes the steering transmission of the pulling force of the driving structure 240 to pull the core of the lateral core pulling slider 210, but also provides a guiding effect on the core pulling of the lateral core pulling slider 210. In order to improve automation and prevent excessive core pulling from affecting reset, the limiting structure 250 can monitor and control the moving distance structure of the lateral core pulling slider 210 or the steering slider 220. When a certain moving distance is reached, the driving structure 240 can be controlled to stop, thereby realizing automatic control of the core pulling distance. The distance is determined by technical personnel in this field according to actual conditions. The utility model first pulls the core of the vertical side structure 301 to avoid interference with the core pulling structure of the bottom side structure 302. The mold space is compact and the core pulling effect is good.

[0032] In some embodiments, as Figure 4 、 6 As shown in Figures 7 and 8, the lateral core-pulling slider 210 includes a forming portion 211 for forming a vertical side structure 301, the steering slider 220 includes a first protrusion structure 221 that slides with the lateral core-pulling slider 210, and the lateral core-pulling slider 210 is provided with a first sliding groove 212 that cooperates with the first protrusion structure 221 on the other side of the forming portion 211.

[0033] The cooperation between the steering slider 220 and the lateral core-pulling slider 210 through the first protrusion structure 221 and the first sliding groove 212 enables the core pulling of the forming part 211, which can effectively transmit the mold opening force of the driving structure 240. The first sliding groove 212 can be arranged horizontally or vertically, such as Figure 4In the embodiment shown, when the first sliding groove 212 is vertically arranged, the steering slider 220 moves vertically for core pulling; when the first sliding groove 212 is horizontally arranged, the steering slider 220 moves horizontally for core pulling, and the structure of the first protrusion structure 221 and the first sliding groove 212 can be a bent pin structure, a T-shaped structure, a dovetail structure or other guiding and cooperating demoulding structure. There is space for core pulling in the front mold core 1, and this space matches the lateral core pulling slider 210, which can limit the core pulling direction and facilitate stable and effective core pulling of the product.

[0034] Furthermore, if Figure 7 As shown, the first protrusion structure 221 is an oblique T-shaped block structure that gradually moves away from the forming portion 211 from top to bottom.

[0035] The inclined T-block structure can drive the core pulling of the forming part 211 when the first sliding groove 212 can slide. The T-shaped slider is simple in design, easy to install and maintain, and can be automatically positioned and locked. Therefore, the need for additional positioning and locking devices can be reduced during the assembly process, ensuring the stability and accuracy of the slider during operation.

[0036] In some embodiments, as Figure 4 、 9 As shown, the steering seat 230 is provided with an accommodating cavity 231 that matches the steering slider 220 .

[0037] Specifically, the steering seat 230 has the functions of protection, prevention and limitation. The steering slider 220, the lateral core-pulling slider 210 and the driving structure 240 are all movable in the steering seat 230. For this purpose, a receiving cavity 231 is designed to accommodate the structure. Figure 4 In one embodiment shown, there are two molding cavities in a mold, so two lateral core-pulling sliders 210 are provided, and the two lateral core-pulling sliders 210 are connected to a separate steering slider 220. At this time, the steering seat 230 is correspondingly provided with two accommodating cavities 231; if the two lateral core-pulling sliders 210 are connected to the same steering slider 220, then there is only one accommodating cavity 231, and the steering seat 230 facilitates the fixation and sliding of the steering slider 220.

[0038] Furthermore, if Figure 4 、 7 As shown in FIG. 9 , the steering slider 220 includes second protrusion structures 222 located on both sides thereof and slidingly connected with the steering seat 230 , and the side walls of the accommodating cavity 231 are provided with second sliding grooves 232 that match with the second protrusion structures 222 .

[0039] Because in the process of core pulling, Figure 4In one embodiment shown, if the steering slider 220 is moved vertically to cause the lateral core-pulling slider 210 to pull the core, the second protrusion structure 222 is vertically arranged on both sides of the steering slider 220, and the side walls of the accommodating cavity 231 are also provided with vertical second sliding grooves 232; if the steering slider 220 is moved horizontally to cause the lateral core-pulling slider 210 to pull the core, the second protrusion structure 222 is horizontally arranged, and the side walls of the accommodating cavity 231 are also provided with horizontal second sliding grooves 232; the guiding energy of the second sliding groove 232 can further improve the core-pulling stability of the steering slider 220. Since the steering slider 220 will slide in the second sliding groove 232 to cause the lateral core-pulling slider 210 to pull the core, the length of the second sliding groove 232 reserves the sliding distance of the steering slider 220 to prevent the steering slider 220 from falling off.

[0040] Furthermore, if Figure 4 、 7 As shown in FIG. 8 , the second bump structure 222 is a rectangular bump structure arranged in a direction perpendicular to the core pulling direction.

[0041] In practice, the steering slider 220 is set to move up and down to drive the lateral core-pulling slider 210 to pull the core. The rectangular protrusion can move along a straight line. The structural stability and the large contact area help to disperse the pressure when the mold is opened and closed, reduce wear and improve the durability of the mold. The rectangular protrusion structure is simple and easy to process, which simplifies the complexity of the mold.

[0042] In some embodiments, Figure 4 、 7 As shown in FIG. 10 , the driving structure 240 includes a driving motor 241 and a third protrusion structure 242 connected to the driving motor 241 . The steering slider 220 is provided with a third sliding groove 223 that is in sliding contact with the third protrusion structure 242 .

[0043] Since the vertical side structure 301 needs to be cored before the mold is opened, it cannot rely on the mold opening force to pull the core, and the external drive motor 241 provides a reliable core pulling force. The drive motor 241 pulls the steering slider 220 to drive the lateral core pulling slider 210 to pull the core by connecting to the third protrusion structure 242. When pulling, the steering slider 220 will be displaced. If the fixed connection is pushed, the connected structure will be distorted and damaged. The third protrusion can slide in the third sliding groove 223 to eliminate the impact of the displacement.

[0044] Furthermore, if Figure 7 、 8 As shown in FIG. 10 , the third sliding groove 223 is a T-shaped groove provided in a direction parallel to the core-pulling direction, and the third protrusion structure 242 is a T-shaped block structure matching the third sliding groove 223 .

[0045] In practice, the steering slider 220 moves up and down relative to the lateral core-pulling slider 210 to drive the lateral core-pulling slider 210 to pull the core, so the driving structure 240 is set on the side with the same moving direction as the core-pulling slider 210, and pulls the steering slider 220 to move up and down relative to the lateral core-pulling slider 210. The steering slider 220 and the driving structure 240 produce relative movement in a direction parallel to the core-pulling direction. The cooperation between the T-block and the T-slot eliminates the influence of this relative movement, and the structure is easy to install and maintain; more specifically, the bottom of the T-block can be rectangular, circular or other shapes, and its side walls only need to cooperate with the two sides of the T-slot to complete the limiting, which is flexible and convenient.

[0046] In some embodiments, as Figure 5 、 8 As shown in Figure 9, the limiting structure 250 includes a first travel switch 251 and a second travel switch 252 arranged on the steering seat 230 for controlling the driving structure 240, and a touch rod 253 arranged between the first travel switch 251 and the second travel switch 252 and connected to the steering slider 220. The first travel switch 251 and the second travel switch 252 are both provided with an induction switch 254 on the side facing the touch rod 253, and the steering seat 230 is provided with a groove 233 that cooperates with the touch rod 253.

[0047] When pulling the core, the steering slider 220 drives the lateral core-pulling slider 210 to pull the core. The limiting structure 250 can limit the moving distance of the steering slider 220 and the moving distance of the lateral core-pulling slider 210. Since most of the structure of the lateral core-pulling slider 210 is in the front mold core 1, the limiting structure 250 is set on the steering slider 220 that slides with the lateral core-pulling slider 210 to facilitate the installation of the limiting structure 250. The limiting structure 250 controls the switch of the driving structure 240 according to the moving distance of the steering slider 220, thereby limiting the core-pulling distance of the lateral core-pulling slider 210; when opening the mold, the driving structure 240 pulls the steering slider 220 to slide upward in the steering seat 230. At this time The touch rod 253 connected to the steering slider 220 moves from the first stroke switch 251 toward the second stroke switch 252. When the touch rod 253 touches the sensing switch 254 on the second stroke switch 252, the drive motor 241 stops working, and the core pulling action is completed. When the mold is closed, the drive structure 240 pulls the steering slider 220 to slide downward in the steering seat 230. At this time, the touch rod 253 connected to the steering slider 220 moves from the second stroke switch 252 toward the first stroke switch 251. When the touch rod 253 touches the sensing switch 254 on the first stroke switch 251, the drive motor 241 stops working, and the resetting of the lateral core pulling slider 210 is completed.

[0048] In some embodiments, as Figure 1-2As shown, the driving structure 240 drives the steering slider 220 in the horizontal direction, and the steering slider 220 drives the lateral core-pulling slider 210 to pull the core in the vertical direction.

[0049] The lateral core-pulling slider 210 can be set to different pulling-out angles according to the core-pulling angles of the vertical side structure 301. In practice, the mold of this embodiment is a horizontal structure, and the vertical side structure 301 needs to be pulled out vertically. The driving structure 240 is designed to be horizontally placed to pull the steering slider 220, and the mold structure is compact.

Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
