Description

Technical Field

[0001] This utility model relates to the field of plastic thermoforming technology, and in particular to a plastic block feeding tool. Background Technology

[0002] Plastic pellets with rods, such as threaded rods used as electrodes, consist of conductive screws encased in conductive silicone. Existing production technology involves first placing the rod into a blind hole in a lower mold, then placing a block of conductive silicone material mixed with a crosslinking agent on top of the rod. The upper mold is then placed on top of the lower mold, with the molding recess on the upper mold aligned with the conductive silicone block on the rod. While heating the conductive silicone block, the lower and upper molds are gradually closed. The hot-melt conductive silicone encapsulates the rod and fills the molding recess, completing the molding process. Simultaneously, the crosslinking agent reacts with the silicone material. After molding, the lower and upper molds are separated, thus completing the manufacturing of the plastic pellet with the rod. However, this technology requires manual placement of the conductive silicone material block mixed with the crosslinking agent on top of the rod, resulting in low efficiency and difficulty in ensuring precise placement. Summary of the Invention

[0003] The purpose of this invention is to provide a plastic block import tool that can overcome one or more of the above-mentioned disadvantages, has high efficiency in placing conductive silicone blocks, and ensures accurate placement.

[0004] The plastic block feeding tool of this utility model is implemented as follows: it includes a lower grid and an upper grid located above the lower grid. Several lower slits constituting the lower grid are parallel to each other and match the rows of blind holes on the mold for producing plastic granules with rods. Several upper slits constituting the upper grid are parallel to each other. The width of the lower slits is the same as the width of the upper slits and corresponds to the width of the conductive silicone block. The lower grid and the upper grid can move relative to each other in a direction perpendicular to the lower slits, so that the lower slits and the upper slits are staggered or overlapped.

[0005] In use, the lower and upper slits are staggered, and several silicone raw material blocks mixed with crosslinking agent are placed in the plastic block inlet tool. Then, the plastic block inlet tool is accurately positioned on the mold. Next, the lower and upper slits are aligned so that several silicone raw material blocks fall simultaneously onto the corresponding rows of rods on the mold. The silicone raw material blocks are stably positioned by the support of the rods.

[0006] Because of the use of a plastic block import tool, each silicone raw material block can be accurately positioned first. When placing the silicone raw material blocks, all the required silicone raw material blocks can be placed on the mold at the same time, so that the mold can be put into the heating and molding process in a short time, while ensuring the accurate positioning of the silicone raw material blocks.

[0007] Preferably, guide posts with stop surfaces are provided on the lower frame sides of the lower grille, and the guide posts extend from the top to the bottom of the lower frame side. Guide grooves that move along the guide posts are provided on the upper frame sides of the upper grille. Through the guide posts and guide grooves, the lower slit and the upper slit can move relative to each other, so as to achieve mutual offset or mutual overlap.

[0008] Compared with existing technologies, this invention has the advantages of high efficiency in placing conductive silicone blocks and accurate placement. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0016] like Figure 1 , 2 As shown in Figures 3, 4, and 5, the plastic block feeding tool of this utility model includes a lower grid 1 and an upper grid 2 located above the lower grid 1. Several lower slits 101 constituting the lower grid 1 are parallel to each other and match the rows of blind holes 6 on the mold 5 that produces plastic pellets 4 with rods 3. Several upper slits 201 constituting the upper grid 2 are parallel to each other. The width of the lower slit 101 is the same as the width of the upper slit 201 and corresponds to the width of the conductive silicone block 7. The lower grid and the upper grid can move relative to each other in a direction perpendicular to the lower slits, so that the lower slits and the upper slits are staggered or overlapped.

[0017] Preferably, guide posts 8 with stop surfaces 801 are provided on the lower frame 102 on both sides of the lower grille 1. The guide posts 8 extend from the lower frame 102 from top to bottom. Guide grooves 9 that move along the guide posts 8 are provided on the upper frame 202 on both sides of the upper grille 2. Through the guide posts 8 and the guide grooves 9, the lower slit 101 and the upper slit 201 can move relative to each other, so as to achieve mutual offset or mutual overlap.

[0018] The guide post 8 is a bolt. A nut 10 is screwed onto the guide post 8, which extends from the top to the bottom frame 102. The end of the guide post 8 located outside the nut 10 serves as a positioning post on the mold.
