[0020] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0021] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are 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, and 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. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0023] An embodiment of this utility model provides a molding die with an upper die oblique pulling mechanism, such as... Figures 1-4 As shown, it includes an upper template 101, an upper mold core 102 disposed below the upper template 101, and a slanted pull assembly 200 disposed on the upper template 101. The slanted pull assembly 200 includes a slider seat 201 slidably connected to the upper template 101, a first sliding rod 202 for forming a first inclined hole 301 and a second sliding rod 203 for forming a second inclined hole 302 that are slidably connected to the slider seat 201, and a drive structure 204 for driving the slider seat 201 to pull the core.

[0024] like Figure 1 As shown, since there are multiple holes around the first inclined hole 301 and the second inclined hole 302, and the front and rear positions of the first inclined hole 301 and the second inclined hole 302 are not consistent, the mold needs to ensure that the forming of these holes and the core-pulling relationship between them do not interfere with each other. For this reason, the inclined pulling mechanism is designed to complete the forming and core-pulling action of the first inclined hole 301 and the second inclined hole 302 without interfering with other holes. The inclined pulling component 200 is set on the upper template 101 to pull the slider seat 201 horizontally. The slider seat 201 in the inclined pulling component 200 is driven by the driving structure 204 to move outward of the mold, and at the same time drives the first sliding rod 202 and the second sliding rod 203 slidably connected to it to pull the core upward obliquely for demolding. This makes it convenient to pull the first inclined hole 301 and the second inclined hole 302 simultaneously without pulling the core separately. The structure is compact, and the core pulling does not affect the surrounding holes, further improving production efficiency.

[0025] In some embodiments, as shown in Figure 2 The oblique drawing assembly 200 includes a first oblique drawing assembly 205 and a second oblique drawing assembly 206 arranged symmetrically.

[0026] The first oblique drawing assembly 205 and the second oblique drawing assembly 206 arranged symmetrically can simultaneously form symmetrically inclined holes, and further, the first oblique drawing assembly 205 and the second oblique drawing assembly 206 can also be different, facilitating the formation of inclined holes of different angles.

[0027] In some embodiments, as shown in Figures 3-4 The bottom of the slider seat 201 is provided with a first sliding groove 207 for guiding the first sliding rod 202 to draw the core and a second sliding groove 208 for guiding the second sliding rod 203 to draw the core, the first sliding rod 202 is provided with a first sliding block 209 matched with the first sliding groove 207, and the second sliding rod 203 is provided with a second sliding block matched with the second sliding groove 208.

[0028] The first sliding groove 207 and the second sliding groove 208 arranged at the bottom of the slider seat 201 are matched with the first sliding block 209 and the second sliding block respectively, facilitating the independent movement of the first sliding rod 202 and the second sliding rod 203 without interference, facilitating the slider seat 201 to complete the core drawing action of the first inclined hole 301 and the second inclined hole 302 at the same time without interfering with other hole positions; the first sliding groove 207 and the second sliding groove 208 accurately guide the movement direction of the first sliding rod 202 and the second sliding rod 203, ensuring that the first sliding rod 202 and the second sliding rod 203 stably draw the core along their respective predetermined trajectories during the core drawing process, and ensuring the forming precision and position precision of the inclined hole.

[0029] Further, as shown in Figure 3 The first sliding groove 207 and the second sliding groove 208 are gradually inclined upward from the outside of the upper die plate 101 to the inside of the upper die plate 101.

[0030] The first sliding groove 207 and the second sliding groove 208 gradually inclined upward enable the slider seat 201 to be driven by the driving structure 204 to the outside when the first sliding rod 202 and the second sliding rod 203 are drawn to the outside of the mold for demolding.

[0031] Further, as shown in Figure 4 The first sliding groove 207 and the second sliding groove 208 are both T-shaped sliding grooves.

[0032] Compared with the dovetail type groove structure, the T-shaped sliding groove is simple to process, durable and reliable in guiding, and can realize guiding with square or circular T-shaped blocks.

[0033] Further, asFigures 3-4 As shown, the first sliding rod 202 comprises a first round rod 211 connected with the first sliding block 209 and a first forming part 212 arranged at the lower end of the first round rod 211 for forming the first inclined hole 301, and the second sliding rod 203 comprises a second round rod 213 connected with the second sliding block and a second forming part 214 arranged at the lower end of the second round rod 213 for forming the second inclined hole 302.

[0034] The first forming part 212 of the first sliding rod 202 and the second forming part 214 of the second sliding rod 203 correspond to the first inclined hole 301 and the second inclined hole 302 respectively, and each sliding rod and forming part can be independently adjusted according to the specific size, angle and position of the corresponding inclined hole, thereby ensuring the forming precision of each hole position and avoiding mutual interference, but also allowing simultaneous core pulling, thereby simplifying the mold structure. Further, if the forming requirements of a certain inclined hole change, only the corresponding sliding rod needs to be replaced or adjusted, without the need for large-scale modification of the entire mold, thereby reducing production costs.

[0035] Further, as shown in the drawings, Figure 2 The driving structure 204 comprises a driving oil cylinder 215 arranged on one side of the upper die plate 101, a T-shaped driving rod 216 connected with the driving oil cylinder 215 and in sliding connection with the sliding block seat 201, and the sliding block seat 201 is provided with a T-shaped third sliding groove matched with the driving rod 216.

[0036] Through the cooperation of the driving oil cylinder 215, the T-shaped driving rod 216 and the sliding block seat 201, accurate and stable driving of the sliding block seat 201 is achieved, and the T-shaped driving rod 216 cooperates with the T-shaped third sliding groove on the sliding block seat 201. This structure can ensure that the driving rod 216 always maintains stable connection with the sliding block seat 201 during movement, eliminating the influence of up-and-down shaking and other situations during movement on the core pulling precision.

[0037] Further, as shown in the drawings, Figure 2 , 4 The sliding block seat 201 is provided with guide sliding blocks 218 on both sides, and the upper die plate 101 is provided with sliding grooves matched with the guide sliding blocks 218, and the sliding grooves are provided with limit blocks 220 above, and the guide sliding blocks 218 slide in the space formed between the sliding grooves and the limit blocks 220.

[0038] The sliding grooves and the limit blocks 220 cooperate to form a space for the guide sliding blocks 218 to move, and the guide sliding blocks 218 slide in the sliding grooves, which can effectively limit the movement direction of the sliding block seat 201 and ensure smooth movement along the predetermined trajectory, thereby improving the precision and reliability of core pulling. This structure can avoid shaking or deviation of the sliding block seat 201 during movement, thereby improving the forming precision of the mold.

[0039] In some embodiments, as Figure 3 As shown in the figure, the insert block 4 is arranged on the upper die plate 101 and is arranged between the first sliding rod 202 and the second sliding rod 203.

[0040] The structure of the insert block 4 is used for forming a hole position, facilitating processing and maintenance, and is arranged between the first sliding rod 202 and the second sliding rod 203 without interfering with each other.

[0041] The terms and words used in the above description and claims are not limited to the literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present application. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present application is provided only for explanation and is not intended to limit the present application as defined by the appended claims and their equivalents.
