Technical Field

[0001] The utility model relates to the technical field of car molds, in particular to a sample making mold which is convenient for cleaning residual glue. Background Art

[0002] Sealing materials are widely used in modern industrial production, and sealing material sample preparation molds are key tools for obtaining high-quality sealing material samples. However, the field of sealing material sample preparation currently faces many severe technical challenges.

[0003] Existing molds for sealing material sample preparation suffer from serious drawbacks during use. When preparing samples, sealant easily adheres to the mold. Due to its strong adhesive properties, cleaning it becomes extremely difficult. Traditional cleaning methods often struggle to completely remove residual sealant, resulting in mold damage during demolding, and even outright scrapping.

[0004] This situation results in molds being disposable, significantly increasing production costs and significantly impacting productivity. Frequent mold changes mean more investment in mold procurement, while also reducing overall productivity due to production interruptions during mold changes. Utility Model Content

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0025] like Figure 1-Figure 5 As shown, the present invention proposes a sample making mold that is convenient for cleaning residual glue, which mainly includes a mounting base 1, a lower mold 2 is embedded in the middle position of the top of the mounting base 1, and a cavity 200 is opened inside the lower mold 2 for accommodating a detachable heat-conducting inner core mold 3;

[0026] Several heating strips 201 are evenly distributed on the inner wall of the chamber 200 to provide heating for the heat-conducting inner core mold 3 to remove residual glue in the mold. A pair of support blocks 203 are provided on each side of the lower mold 2. The support blocks 203 are fixed to the top of the mounting base 1 and are symmetrically distributed. A slide rail 204 is installed on the top of each support block 203.

[0027] Several guide rods 7 are also provided on the top of the mounting base 1. These guide rods 7 play a guiding and supporting role. The tops of the several guide rods 7 are commonly connected to a top plate 8. A third telescopic cylinder 10 is installed downwardly on the top of the top plate 8. After the telescopic rod of the third telescopic cylinder 10 passes through the top plate 8, the top of the telescopic rod is fixedly connected to a pressure plate 9. Guide sleeves 902 are provided on the four corners of the pressure plate 9. Several guide rods 7 are respectively located in the several guide sleeves 902, ensuring that the pressure plate 9 can move up and down stably under the guidance of the guide rods 7;

[0028] A pressing and fixing assembly 4 is symmetrically provided on both sides of the lower mold 2. Each pressing and fixing assembly 4 includes a first telescopic cylinder 400. The first telescopic cylinder 400 is located between the two support blocks 203. The top of the telescopic rod of the first telescopic cylinder 400 is connected to a connecting plate 401. A limit plate 402 is fixed on the connecting plate 401. The limit plate 402 is movably provided on the support block 203. A slide groove 403 is provided at the bottom of the limit plate 402 at a position corresponding to the slide rail 204. The slide rail 204 is provided in the slide groove 403, so that the limit plate 402 can move stably along the slide rail 204 under the push of the first telescopic cylinder 400, thereby accurately pressing and fixing the heat-conducting inner core mold 3.

[0029] An installation chamber 5 is provided in the installation base 1, and the installation chamber 5 is located directly below the lower mold 2. A second telescopic cylinder 6 is provided in the installation chamber 5, and a ejection plate 600 is provided on the top of the telescopic rod of the second telescopic cylinder 6. A telescopic hole 202 is provided in the middle of the interior of the lower mold 2, and the telescopic rod of the second telescopic cylinder 6 is movably arranged in the telescopic hole 202. A groove 300 corresponding to the ejection plate 600 is provided at the bottom of the thermal core mold 3, and the ejection plate 600 is fitted in the groove 300. When the product is formed, the second telescopic cylinder 6 can eject the product from the thermal core mold 3 through the ejection plate 600;

[0030] An upper mold 900 is provided at the bottom of the pressing plate 9 at a position corresponding to the heat-conducting inner core mold 3 . Glue injection holes 901 are also provided in the upper mold 900 and the pressing plate 9 for injecting melted glue into the heat-conducting inner core mold 3 .

[0031] When using this equipment for mold production, first, it is necessary to select the heat-conducting inner core mold 3 corresponding to the production and install it into the lower mold 2. Then, the two first telescopic cylinders 400 are started at the same time, so that they push the limit plates 402 to move synchronously inward along the slide rails 204 until one side of the two limit plates 402 is respectively placed on both sides of the top of the heat-conducting inner core mold 3, thereby accurately positioning the heat-conducting inner core mold 3. Then, the third telescopic cylinder 10 is started to drive the pressing plate 9 to slide downward as a whole until the upper mold 900 is tightly pressed on the heat-conducting inner core mold 3, ensuring the stability and sealing of the mold during the production process.

[0032] Then, slowly inject the melted glue from the glue injection hole 901 so that the glue can flow smoothly into the heat-conducting inner core mold 3 until it is completely filled. During the glue injection process, pay attention to controlling the flow rate and injection amount of the glue to avoid glue overflow or insufficient filling.

[0033] After the glue is completely injected, wait for it to cool and solidify. During the cooling and solidification process, ensure that the ambient temperature around the equipment is stable to avoid temperature fluctuations that affect product quality.

[0034] When the glue cools and solidifies, the pressing plate 9 can be raised. Then, the second telescopic cylinder 6 is started, and the ejector plate 600 is used to eject the formed product from the mold. During the ejection process, it is important to control the rising speed and force of the ejector plate 600 to avoid damage to the product.

[0035] When there is residual glue that is difficult to clean in the corners or crevices of the thermal core mold 3, you can start heating by activating several heating strips 201 in the lower mold 2. The heat generated by the heating strips 201 is transferred through the thermal core mold 3 to melt the residual glue again, making it easy to clean. Finally, use appropriate tools to clean out the melted residual glue to ensure the cleanliness of the thermal core mold 3 for next use.

[0036] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
