Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for molding silicone stamps. Background Technology

[0002] In the manufacturing of products made of elastic materials such as silicone, such as silicone stamps, specialized molding dies are used. These dies typically consist of an upper mold and a lower mold, which, when closed, form a sealed cavity. Under the pressure and temperature provided by equipment such as a vulcanizing machine, the silicone raw material undergoes a vulcanization reaction within the mold cavity, thereby molding the desired silicone product. Molds are often decorated with text, markings, or patterns and are crucial tools for shaping and defining the surface features of silicone products in mass production.

[0003] However, most existing silicone stamp molding molds are one-piece structures. When different silicone stamps with different text logos or patterns need to be made, traditional molds require the entire lower mold to be remade every time the text logo or pattern is changed. This not only significantly increases the mold manufacturing cost but also extends the production cycle and reduces production efficiency.

[0004] In addition, if the text or pattern parts of the integral mold are worn or damaged during use, the entire mold must be replaced, which is costly and inconvenient.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mold for molding silicone stamps, comprising an upper mold and a lower mold, wherein the lower mold is provided with a plurality of molding grooves;

[0008] The lower template is provided with an identification module, which includes a base plate and multiple identification blocks disposed on the base plate;

[0009] The lower template has a placement groove, and the placement groove has a fitting groove that communicates with the forming groove.

[0010] The base plate is detachably fixed in the storage groove, the marking block is interlocked with the fitting groove, and the upper surface of the marking block is flush with the bottom surface of the forming groove.

[0011] As a further embodiment of this utility model: a bottom cover is provided in the storage groove at the lower end of the base plate, the bottom cover presses the base plate tightly into the storage groove, and a locking component is provided between the bottom cover and the lower template to lock the bottom cover in the storage groove.

[0012] As a further embodiment of this utility model: the locking assembly includes a locking block, a knob, and a screw;

[0013] The inner wall of the placement groove is provided with several retraction grooves, and the retraction grooves are provided with through holes that communicate with the outer surface of the lower template. The side end of the bottom cover is provided with several locking grooves corresponding to the retraction grooves.

[0014] The screw passes through the through hole, with one end protruding and connected to the knob on the outside of the lower template, and the other end extending into the retraction groove. The two ends of the locking block are located in the locking groove and the retraction groove respectively, and the locking block is provided with a screw hole. The screw passes through and is screwed into the screw hole. The locking block can be completely retracted into the retraction groove.

[0015] As a further embodiment of this utility model: a bearing is provided in the through hole, and the bearing is sleeved on the screw.

[0016] As a further embodiment of this utility model: a positioning post is provided on the base plate, and a positioning groove is provided on the top wall of the placement groove, and the positioning post and the positioning groove are correspondingly inserted and engaged.

[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: When different marking modules need to be replaced, the detachable base plate fixed inside the storage groove is removed, allowing the marking block that interlocks with the fitting groove to detach. Then, marking modules with different markings are installed by placing the base plate inside the storage groove and inserting the marking block into the fitting groove. The marking block fits tightly with the fitting groove, and its upper end face is flush with the bottom surface of the molding groove. During the silicone stamp molding process, the marking pattern on the marking block will form the corresponding marking on the finished product, thereby realizing the modularization between the marking module and the lower template. This facilitates the replacement of marking modules according to different needs, thereby reducing mold manufacturing costs and improving production efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 A mold for molding silicone stamps includes an upper template 1 and a lower template 2, wherein the lower template 2 is provided with a plurality of molding grooves 3;

[0029] The lower template 2 is provided with an identification module 4, which includes a base plate 41 and multiple identification blocks 42 disposed on the base plate 41;

[0030] The lower template 2 is provided with a placement groove 21, and the placement groove 21 is provided with a fitting groove 22 that communicates with the forming groove 3;

[0031] The base plate 41 is detachably fixed in the placement groove 21, the marking block 42 is interlocked with the fitting groove 22, and the upper end surface of the marking block 42 is flush with the bottom surface of the forming groove 3.

[0032] Specifically, when different logo modules 4 need to be replaced, the detachable base plate 41 fixed inside the storage groove 21 is removed, allowing the logo block 42, which interlocks with the fitting groove 22, to detach. Then, the logo modules 4 with different logos are installed, that is, the base plate 41 is placed inside the storage groove 21, and the logo block 42 is inserted into the fitting groove 22. The logo block 42 fits tightly with the fitting groove 22, and its upper end face is flush with the bottom surface of the molding groove 3. During the silicone stamp molding process, the logo pattern on the logo block 42 will form the corresponding logo on the finished product, thereby realizing the modularity between the logo module 4 and the lower template 2. This facilitates the replacement of the logo module 4 according to different needs, thereby reducing mold manufacturing costs and improving production efficiency.

[0033] In some embodiments, a bottom cover 5 located at the lower end of the base plate 41 is provided in the storage groove 21. The bottom cover 5 presses the base plate 41 against the inside of the storage groove 21, and a locking component 6 is provided between the bottom cover 5 and the lower template 2 to lock the bottom cover 5 in the storage groove 21.

[0034] Specifically, the locking component 6 is used to lock the bottom cover 5, and the bottom cover 5 restricts the bottom plate 41 in the storage groove 21 and presses it tightly, thereby keeping the position of the bottom plate 41 stable. When the locking component 6 is released from the bottom cover 5, the bottom cover 5, the bottom plate 41 and the marking block 42 can be taken out and replaced in sequence.

[0035] The locking component 6 is designed between the bottom cover 5 and the lower template 2, which can reduce the processing of the marking module 4. One lower template 2 can be used with multiple marking modules 4, thus further reducing the production cost.

[0036] In some embodiments, the locking assembly 6 includes a locking block 61, a knob 62, and a screw 63;

[0037] Among them, the inner wall of the storage groove 21 is provided with several retraction grooves 23, and the retraction grooves 23 are provided with through holes 24 that communicate with the outer surface of the lower template 2. The bottom cover 5 is provided with several locking grooves 51 corresponding to the retraction grooves 23.

[0038] The screw 63 passes through the through hole 24, with one end protruding and connecting to the knob 62 on the outside of the lower template 2, and the other end extending into the retraction groove 23. The two ends of the locking block 61 are located in the locking groove 51 and the retraction groove 23 respectively, and the locking block 61 is provided with a screw hole 64. The screw 63 passes through and is screwed into the screw hole 64, wherein the locking block 61 can be completely retracted into the retraction groove 23.

[0039] Specifically, during disassembly, rotating the knob 62 drives the screw 63. The screw 63, through its connection with the screw hole 64, causes the locking block 61 to move into the retraction groove 23. When the locking block 61 is fully retracted into the retraction groove 23, its other end will disengage from the locking groove 51, thereby releasing the locking of the bottom cover 5, so that the bottom cover 5, the bottom plate 41, and the marking block 42 can be removed and replaced in sequence.

[0040] During installation, the base plate 41 and the marker block 42 are installed first, and then the bottom cover 5 is placed into the storage groove 21. At this time, the knob 62 is turned to drive the screw 63, so that one end of the locking block 61 is inserted into the locking groove 51 again, so as to fix the bottom cover 5 inside the storage groove 21, thus completing the fixing of the base plate 41 and the marker block 42.

[0041] The retraction groove 23 and the locking groove 51 are both square grooves, while the locking block 61 is a square block that slides with the retraction groove 23 and the locking groove 51. It can provide a guiding movement effect for the locking block 61 and prevent the locking block 61 from rotating when the screw 63 rotates.

[0042] In some embodiments, a bearing 7 is provided in the through hole 24 and is sleeved on the screw 63 to provide stability to the screw 63 and ensure that the screw 63 can rotate smoothly. The area where the bearing 7 is sleeved is the non-threaded area on the screw 63.

[0043] In some embodiments, a positioning post 43 is provided on the base plate 41, and a positioning groove 25 is provided on the top wall of the receiving groove 21. The positioning post 43 and the positioning groove 25 are correspondingly inserted and engaged. This enhances the accuracy of the position of the base plate 41 and ensures a tight fit between the marking block 42 and the fitting groove 22.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
