Technical Field

[0001] The utility model relates to a plastic mold, in particular to a precision plastic mold containing a temperature control component, and belongs to the technical field of plastic molds. Background Technique

[0002] A plastic mold is a short name for a combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. Coordinated changes in the convex and concave molds and the auxiliary molding system of the mold can process a series of plastic parts with different shapes and sizes. A hot runner is a method of heating to keep the plastic in the runner and the gate in a molten state. A hot runner system generally consists of several parts such as a hot nozzle, a manifold plate, a temperature control box, and accessories. A hot runner mold is a mold that uses a heating device to keep the melt in the runner from solidifying all the time. Because it has a shorter molding cycle than a traditional mold and saves more raw materials, it is widely used.

[0003] However, when installing the hot runner system, it is generally fixed to the inner wall of the mold through positioning screws. After installation, the operator also needs to fix a stop block to limit the connecting wires on the hot runner system. The fixing steps are relatively cumbersome and it is not convenient to position the hot runner system and the connecting wires at the same time. Content of the Utility Model

When the end of the rotating plate 403 rotates to the top of the hot runner system 5, the hot runner system 5 can be limited.

[0027] As a technical optimization scheme of the present utility model, the rotating plate 403 is rotatably connected to the hot runner system 5. The positioning rod 404 rotates at the position of the positioning hole 7. When the through hole provided on the rotating plate 403 is aligned with the positioning hole 7, a tool can be used to threadedly install the positioning rod 404 into the interior of the hot runner system 5.

[0028] As a technical optimization scheme of the present utility model, the height of the rotating plate 403 is greater than the height of the hot runner system 5, and the rotating plate 403 is rotatably connected to the mold body 1. The rotating plate 403 limits the hot runner system 5, so that the hot runner system 5 can be installed inside the mold body 1.

[0029] As a technical optimization scheme of the present utility model, the installation mechanism 3 includes a connecting block 301 and a lifting ring 302. The connecting block 301 is fixedly installed on the mold body 1. The lifting ring 302 is fixedly connected to the connecting block 301. Several jacks 304, clamping grooves 305 and limiting grooves 306 are provided on the mold body 1. A wire storage groove 303 is provided on the inner wall of the mold body 1 close to the connecting block 301. After the hot runner system 5 is installed, the connecting wires on the hot runner system 5 can be stored through the wire storage groove 303.

[0030] As a technical optimization scheme of the present utility model, several of the jacks 304 are symmetrically arranged in pairs of two. The jacks 304 are located at the corner parts of the mold body 1. When the insertion rod 205 is clamped into the jack 304, the cover plate 201 can be installed on the top of the mold body 1.

[0031] As a technical optimization solution of the present utility model, the part of the mold body 1 close to the card slot 305 is arranged in an inclined surface structure, and the part of the mold body 1 close to the limit slot 306 is arranged in an arc surface structure. Through the card slot 305 and the limit slot 306, it is convenient to quickly fix and install the cover plate 201.

[0032] As a technical optimization solution of the present utility model, the sealing mechanism 2 includes a cover plate 201 and a clamping plate 202. The clamping plate 202 is snap-connected to the mold body 1. A cover plate 201 is fixedly installed between the two clamping plates 202. A limit block 203 is fixedly connected to the bottom end of the clamping plate 202. A fixing bolt 204 passes through the limit block 203. A plurality of insertion rods 205 are fixedly connected to the cover plate 201. By means of the fixing bolt 204, the limit block 203 can be fixed on the mold body 1.

[0033] As a technical optimization solution of the present utility model, a plurality of the insertion rods 205 are symmetrically arranged in pairs at the bottom end of the cover plate 201, and the insertion rods 205 are snap-connected to the mold body 1. The diameter of the insertion rod 205 is equal to the diameter of the insertion hole 304. The arrangement of the insertion rods 205 can facilitate the quick installation of the cover plate 201 to the top of the mold body 1.

[0034] As a technical optimization solution of the present utility model, the clamping plate 202 is snap-fitted at the card slot 305, and the limit block 203 is snap-fitted at the limit slot 306. The fixing bolt 204 is threadedly connected to the mold body 1. When the fixing bolt 204 is threadedly installed into the mold body 1, the limit block 203 can be fixed.

[0035] When the utility model is in use, first, place the hot runner system 5 at the installation groove 6 provided on the mold body 1, and then straighten the connecting wires installed on the hot runner system 5 so that the connecting wires are located at the wire storage groove 303 provided inside the mold body 1. When fixing the hot runner system 5, the operator can rotate the rotating plate 403 fixed on the coupling shaft 401 by hand. Since through holes are provided at the end of the rotating plate 403 away from the coupling shaft 401, when the rotating plate 403 rotates at the rotating groove 402 provided inside the mold body 1, the through holes on the rotating plate 403 can be communicated with the positioning holes 7 provided on the hot runner system 5. Then, penetrate the positioning rod 404 through the inner wall of the rotating plate 403, so that the end of the positioning rod 404 is located inside the hot runner system 5. Use a tool to rotate the positioning rod 404, and it can be threadedly installed inside the hot runner system 5. Thus, while facilitating the fixation of the hot runner system 5 through the rotating plate 403, the rotating plate 403 can also limit the connecting wires on the hot runner system 5, so that the connecting wires can be neatly stored at the wire storage groove 303; there are two groups of jacks 304 provided on the mold body 1. When installing the installation cover plate 201, the two insertion rods 205 fixed at its bottom end can be snap-fitted into the jacks 304. When the insertion rods 205 are located at the jacks 304, the cover plate 201 can be in contact with the top end of the mold body 1. Two clamping plates 202 are symmetrically and fixedly installed at the bottom end of the cover plate 201. When the cover plate 201 is in contact with the mold body 1, the clamping plates 202 can be snap-fitted into the clamping grooves 305 provided inside the mold body 1, so that the limiting blocks 203 fixed at the bottom end of the clamping plates 202 are snap-fitted into the limiting grooves 306 provided inside the mold body 1. Since the fixing bolts 204 penetrate through the limiting blocks 203, when using a tool to threadedly install the fixing bolts 204 into the mold body 1, the limiting blocks 203 can be fixed on the side wall of the mold body 1, thus facilitating the sealing of the inside of the mold body 1 through the cover plate 201; then, tie the lifting rope to the lifting ring 302 fixed on the connecting block 301, and the mold body 1 can be moved through the lifting rope.
