The description includes various specific details to help understanding, but these details should be regarded as 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 utility model.

[0024] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0026] Before specifically describing the encapsulation mold for preventing the product from being crushed, it is necessary to introduce the product to be encapsulated. Figure 1 As shown, the product 10 is in a box-like structure, having a receiving groove 11 , which is open on the top surface of the product 10 , a groove 12 is provided on the bottom surface of the product 10 , and a notch 13 is provided on the outer edge of the product 10 .

[0027] The embodiment of the utility model provides a plastic encapsulation mold to prevent the product from being crushed. Figure 2-6 As shown, it includes an upper mold assembly 100 and a lower mold assembly 200. The upper mold assembly 100 is arranged above the lower mold assembly 200, and the two can move in the vertical direction to close or separate the molds. The upper mold assembly 100 includes an upper mold plate 110 located at the bottom thereof, an upper mold core 120 arranged on the bottom surface of the upper mold plate 110, and a plurality of slider mechanisms 130 arranged on the bottom surface of the upper mold plate 110. The slider mechanism 130 includes a slider 131, and the slider 131 can slide relative to the upper mold plate 110. A protruding insert 140 is also provided on the bottom surface of the upper mold core 120, and the slider 131 is arranged around the insert 140 so as to abut the product 10 from all sides.

[0028] The lower mold assembly 200 includes a lower mold plate 210 located at the top thereof, a lower mold core 220 disposed on the top surface of the lower mold plate 210, and a plurality of drive mechanisms 230 disposed on the top surface of the lower mold plate 210 corresponding to the slider mechanism 130. Specifically, the drive mechanisms 230 correspond to the slider mechanism 130 one by one, and each slider mechanism 130 is provided with a corresponding drive mechanism 230. The drive mechanisms 230 cooperate with the slider mechanism 130. During the mold closing and mold opening process, the drive mechanisms 230 can drive the slider 131 to move. A positioning block 240 is disposed on the lower mold core 220. The positioning block 240 can elastically slide relative to the lower mold core 220 in a direction parallel to the mold closing direction. The product 10 to be encapsulated is used to be placed on the positioning block 240.

[0029] After the upper mold assembly 100 and the lower mold assembly 200 are molded together, the insert 140 can be inserted into the receiving groove 11 of the product 10 and press the product 10 to be encapsulated against the positioning block 240. As a result, the positioning block 240 and the insert 140 will clamp and fix the product 10 to be encapsulated to position the product. Since the positioning block 240 can elastically slide relative to the lower mold core 220 in a direction parallel to the mold closing direction, when the insert 140 is pressed down, the elastic sliding of the positioning block 240 can provide a buffer, effectively preventing the positioning block 240 and the insert 140 from crushing the product 10. At the same time, the driving mechanism 230 drives the corresponding slider 131 to abut against the side of the product 10 to be encapsulated, limiting the lateral movement of the product 10, and achieving a secondary positioning effect on the product, thereby accurately positioning the product.

[0030] After the upper mold assembly 100 and the lower mold assembly 200 are opened, the insert 140 can be pulled out from the receiving groove 11 of the product 10, and the driving mechanism 230 drives the corresponding slider 131 away from the product 10, and the operator can take away the product 10 that has completed the secondary encapsulation from the positioning block 240.

[0031] It should be noted that in order for Fang Bo to observe the portion covered by the upper mold core 120, Figure 2 The upper mold core is removed.

[0032] In some embodiments, Figure 3 As shown, the surface of the lower mold core 220 is provided with a guide groove extending along the mold closing direction, the positioning block 240 is arranged in the guide groove and can slide in the guide groove, and an elastic member 250 is arranged in the guide groove, the elastic member 250 abuts the positioning block 240, and the positioning block 240 is elastically slid in the guide groove through the elastic member 250, and when the insert 140 is pressed down, the elastic member 250 can provide elastic buffering.

[0033] Furthermore, a guide column 251 may be provided in the guide groove, and a socket extending along the mold closing direction may be provided on the bottom surface of the positioning block 240, the guide column 251 is inserted into the socket, and the elastic member 250 is a spring sleeved on the guide column 251, and the upper end of the spring abuts against the positioning block 240, thereby, the elastic member 250 can provide a stable elastic force in a direction parallel to the mold closing direction.

[0034] In some embodiments, the positioning block 240 is provided with a positioning protrusion 241, which is used to be inserted into the groove 12 at the bottom of the product 10 to be encapsulated, so as to better position the product 10 and keep the product 10 stable. The shape and size of the positioning protrusion 241 can be respectively matched with the shape and size of the groove 12, so that the positioning protrusion 241 can be accurately inserted into the groove 12.

[0035] In some embodiments, a sliding groove 121 is provided on the surface of the upper mold core 120, the insert 140 is fixed on the inner wall of the sliding groove 121, a portion of the slider 130 is embedded in the sliding groove 121 and can slide along the extension direction of the sliding groove 121, and the sliding groove 121 will guide the slider 130 so that the slider 130 can slide stably along the preset direction.

[0036] As required, a plurality of sliding grooves 121 may be provided, each slider 131 corresponds to one sliding groove 121 , the inner ends of all the sliding grooves 121 are connected to each other, and the insert 140 may be provided on the inner wall of one of the sliding grooves 121 .

[0037] Furthermore, a protrusion 132 is provided on the surface of the slider 131. After the upper mold assembly 100 and the lower mold assembly 200 are closed, the protrusion 132 abuts against the upper mold core 120, which can limit the slider 131 from continuing to slide along the original direction and avoid the slider 131 from crushing the product 10.

[0038] In some embodiments, the insert 140 includes a notch insert 141 . After the upper mold assembly 100 and the lower mold assembly 200 are molded together, the notch insert 141 is inserted into the notch 13 of the product 10 to be encapsulated to more accurately position the product 10 .

[0039] In some embodiments, the driving mechanism 230 includes an inclined guide column, and the slider 131 is provided with an inclined guide hole 133 adapted to the inclined guide column. During the process of closing or opening the upper mold assembly 100 and the lower mold assembly 200, the inclined guide column is inserted into the inclined guide hole 133 and can slide along the inclined guide hole 133, thereby driving the slider 131 to slide.
