[0023] The utility model provides the following description of reference drawing to help comprehensively understand various embodiments of the utility model as defined in the claim and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.

[0024] In the description of the utility model, the orientation description such as the orientation or position relation indicated by up, down, front, back, left, right etc. based on the orientation or position relation shown in the drawing is only for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the utility model.

[0025] It should be understood that when one element (for example, a first element) is "connected" with another element (for example, a second element), the element can be directly connected with the other element, or there can be an intervening element (for example, a third element) between the element and the other element.

[0026] The embodiment of the utility model provides a built-in inclined top structure of vehicle refrigerator forming die, as shown in Figures 2-5 , comprising: lower mould core 1, the lateral core-pulling assembly 2 of setting in one side of lower mould core 1 and the inclined top assembly 3 of setting in lateral core-pulling assembly 2 and with lower mould core 1 is connected, and the delay structure 301 of being connected with lower mould core 1 is included in the inclined top assembly 3;

[0027] When the lateral core-pulling assembly 2 carries out core pulling in the first direction, the inclined top assembly 3 is connected with lower mould core 1 through the delay structure 301 and carries out core pulling to the second direction, then the delay structure 301 is separated from lower mould core 1, and the inclined top assembly 3 moves along with the lateral core-pulling assembly 2 in the first direction.

[0028] The lateral core-pulling assembly 2 is used for structures on the first sidewall of the molded product that can be core-pulled in the first direction; the inclined ejector assembly 3 is used for hole structure and cylindrical block structures on the second sidewall of the molded product that can be core-pulled in the second direction; when the lateral core-pulling assembly 2 starts to core-pull in the first direction, the inclined ejector assembly 3 is pulled by the lower mold core 1 through the time-delay structure 301, slides upward opposite to the lateral core-pulling assembly 2, and core-pulls in the second direction under the guidance of the lateral core-pulling assembly 2; when the lateral core-pulling assembly 2 moves to a certain distance, the inclined ejector assembly 3 has completed core-pulling, at which time the time-delay structure 301 is separated from the lower mold core 1, and the inclined ejector assembly 3 immediately retreats in the first direction with the lateral core-pulling assembly 2, without affecting the subsequent demolding of the product. The time-delay structure 301 can be a spring 315 cooperating with a magnetic attraction structure, an electric control and release structure, or a rubber plug structure that can realize connection through friction force, and other structures that can make the inclined ejector assembly 3 realize the time-delay function of being connected first and then separated from the lower mold core 1. Compared with the traditional tunnel core-pulling structure, through the control of the time-delay structure 301, the core-pulling action of the inclined ejector assembly 3 in the second direction is independent of the first direction core-pulling action of the lateral core-pulling assembly 2, ensuring that the inclined ejector assembly 3 is separated from the lower mold core 1 only after completing the core-pulling in the second direction, avoiding the jamming or damage to the product caused by premature separation. The coordinated action of the inclined ejector assembly 3 and the lateral core-pulling assembly 2 reduces the operation in the mold opening process, eliminates the need for multi-step core-pulling operation, shortens the production cycle, eliminates the need for structures such as oil cylinders, and reduces production costs.

[0029] In some embodiments, as shown in Figure 3 The inclined ejector assembly 3 includes an inclined ejector rod 302 slidably connected with the lateral core-pulling assembly 2, a forming part 303 provided at the front end of the inclined ejector rod 302 for forming hole structure and cylindrical block, and an inclined ejector seat 304 slidably connected with the inclined ejector rod 302 and the lateral core-pulling assembly 2, and the time-delay structure 301 is provided on the inclined ejector seat 304.

[0030] The inclined ejector assembly 3 realizes multi-directional movement through the sliding connection between the inclined ejector rod 302 and the inclined ejector seat 304, and the sliding connection between the inclined ejector seat 304 and the lateral core-pulling assembly 2, reduces the friction and wear between the moving parts, and improves the stability of the mold. When the lateral core-pulling assembly 2 starts to core-pull, the inclined ejector rod 302 remains connected with the lower mold core 1 through the time-delay structure 301, which can control the connection and separation time of the inclined ejector assembly 3 and the lower mold core 1, and ensure the accurate completion of the core-pulling action of the forming part 303 in the second direction.

[0031] Further, as shown in Figure 3 The lower end of the inclined ejector rod 302 is provided with an inclined ejector sliding block 306, and the inclined ejector seat 304 has an inclined ejector sliding groove that slidably cooperates with the inclined ejector sliding block 306.

[0032] The cooperation between the inclined top sliding block 306 and the inclined top sliding groove provides accurate guidance for the movement of the shaped part 303 in the second direction, ensures smooth movement of the shaped part 303 along the predetermined track in the side core-pulling assembly 2 cooperating with the inclined top sliding block 306 during the core-pulling and resetting processes, avoids interference or damage caused by movement deviation, and improves the operation accuracy and stability of the mold.

[0033] Further, as shown in Figures 3-4 The inclined top sliding groove is an L-shaped groove, and the inclined top sliding block 306 is an inverted L-shaped protrusion matched with the inclined top sliding groove.

[0034] Compared with the traditional T-shaped groove, the L-shaped groove structure of the inclined top sliding groove is simple and easy to process, and the inverted L-shaped protrusion can be directly connected with the L-shaped groove, and the upper side is limited by the side core-pulling assembly 2, which is simple in structure, easy to process and easy to assemble.

[0035] Further, as shown in Figure 5 The inclined top seat 304 further includes a base sliding protrusion 309 slidingly connected with the side core-pulling assembly 2, the side core-pulling assembly 2 has a base sliding groove and a fixed block 311 matched with the base sliding protrusion 309 for sliding connection, and the base sliding protrusion 309 slides in the space formed between the base sliding groove and the fixed block 311.

[0036] The space formed between the base sliding groove and the fixed block 311 for the sliding of the base sliding protrusion 309 provides accurate guidance for the inclined top seat 304, the fixed block 311 facilitates the installation of the base sliding protrusion 309, ensures smooth movement of the base sliding protrusion 309 in the first direction during the core-pulling and resetting processes, avoids interference or damage caused by movement deviation, and improves the operation accuracy and stability of the mold.

[0037] Further, as shown in Figures 3-4 The side core-pulling assembly 2 has a top rod sliding groove 312 matched with the inclined top rod 302 and a base groove 313 for accommodating the inclined top seat 304, and the side surface of the base groove 313 is spaced apart from the side surface of the inclined top seat 304 by a predetermined distance.

[0038] The top rod sliding groove 312, as shown in Figure 3 facilitates the installation of the inclined top rod 302 and provides displacement space and guidance for the inclined core-pulling of the inclined top rod 302 in the second direction; and Figure 4 The side surface of the base groove 313 is spaced apart from the side surface of the inclined top seat 304 by a predetermined distance, which is determined by a person skilled in the art according to the actual core-pulling movement distance required by the inclined top rod 302, to avoid collision with the side core-pulling assembly 2 continuously core-pulling in the first direction when the inclined core-pulling assembly 3 is connected with the lower mold core 1 through the time delay structure 301 and core-pulling.

[0039] Further, as shown in Figure 4As shown, the lower die core 1 is provided with a limiting protrusion 314 for limiting displacement of the inclined ejector seat 304, and the bottom of the inclined ejector seat 304 is provided with a limiting groove 316 matched with the limiting protrusion 314.

[0040] The matching of the limiting protrusion 314 and the limiting groove 316 can limit the displacement of the inclined ejector seat 304, ensure that the inclined ejector assembly 3 is kept in a predetermined position, and improve the operation accuracy and reliability of the mold.

[0041] Further, as shown, Figure 4 the delay structure 301 is a nylon plug inserted into the inclined ejector seat 304, and the lower die core 1 is provided with an insertion hole 317 matched with the nylon plug.

[0042] Under the action of the nylon plug, the inclined ejector seat 304 is connected with the lower die core 1 by friction, and is not moved at the beginning with the movement of the side core pulling assembly 2, so that the inclined ejector seat 304 moves in the opposite direction relative to the side core pulling assembly 2, and the forming part 303 can thus core-pulling in the second direction, and the nylon plug and the lower die core 1 are separated subsequently, facilitating the inclined ejector structure to continue to move in the first direction with the side core pulling assembly 2, without affecting the subsequent product demolding.

[0043] In some embodiments, as shown, Figures 2-3 the side core pulling assembly 2 includes a core-pulling seat 201 arranged on one side of the lower die core 1, a forming insert 202 connected with the core-pulling seat 201 and arranged above the lower die core 1, and a driving structure 204 for pulling the core-pulling seat 201, and the inclined ejector assembly 3 is arranged in the forming insert 202.

[0044] The structural design of the core-pulling seat 201 and the forming insert 202 can withstand a large core-pulling force, and provides stable support for the forming insert 202 and the inclined ejector assembly 3 arranged in the forming insert 202. By arranging the inclined ejector assembly 3 in the core-pulling seat 201, the internal space of the forming insert 202 is reasonably utilized, and meanwhile, multiple direction forming and core-pulling can be realized.

[0045] Further, as shown, Figure 2 the side core pulling assembly 2 further includes a first limit switch 205 and a second limit switch 206 arranged in the first direction, and a stop block 207 arranged on the core-pulling seat 201, and the stop block 207 reciprocates and touches between the first limit switch 205 and the second limit switch 206.

[0046] The first limit switch 205 and the second limit switch 206 can provide real-time signals when the stop block 207 is triggered and transmit the real-time signals to the driving structure 204, so as to control the core-pulling stroke of the core-pulling seat 201 in the first direction, and ensure the consistency of the core-pulling action, effectively preventing the core-pulling seat 201 from moving excessively in the movement process.

Accordingly, it should be apparent to those skilled in the art that the above description of various embodiments of the present application is provided only to explain the present application and it would not be construed as limiting the present application as defined by the appended claims and their equivalents.
