According to the injection mold, the condition that a heating pipe can be replaced without frequently dismounting the injection mold, and the service life is relatively long.

Description

Injection mold

Technical field:

The utility model relates to a kind of injection mold.

Background technology:

At present, when the narrower plastic product of some forming temperature scopes of injection mo(u)lding, usually need be provided with heat-generating pipe at solid plate and the moving platen of injection mold, guarantee the temperature of plastic shaping, because the power of heat-generating pipe is lower, the life-span is shorter, during long-time heating work, be easy to damage, therefore, people just need dismantle injection mold frequently and change heat-generating pipe, and are so just cumbersome.

The utility model content:

The technical problems to be solved in the utility model is that a kind of injection mold that injection mold is changed heat-generating pipe that do not need to dismantle frequently is provided.

Technical solution of the present utility model is, provide a kind of injection mold with following structure: comprise top clamping plate from top to bottom successively, solid plate, moving platen, cushion block and Bottom clamp plate, solid plate is provided with cover half benevolence, moving platen is provided with mavable module core, wherein, cover half benevolence perisporium is provided with all first heating tanks, the mavable module core outer wall is provided with second heating tank, be placed with the first heating wire rod and tight with the first copper bar embedding in first heating tank, be placed with the second heating wire rod and tight with the second copper bar embedding in second heating tank, the two ends of the first heating wire rod are equipped with the first plug wire head, and the two ends of the second heating wire rod are equipped with the second plug wire head, and solid plate is provided with open slot, the first plug wire head is positioned at open slot, moving platen is provided with groove, and the second plug wire head is positioned at groove, and moving platen is provided with two cable-through holes that communicate with groove.

After adopting above structure, compared with prior art, the utility model injection mold has the following advantages: compare with heat-generating pipe, because it is big that heating wire rod itself has caloric value, the characteristics that life-span is long, therefore the utility model injection mold that has adopted the heating wire rod that cover half Renhe mavable module core is heated does not need to dismantle frequently injection mold and changes the heating wire rod, and service life is longer.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments the utility model injection mold is described in further detail:

As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, in this specific embodiment, the utility model injection mold comprises top clamping plate 5 from top to bottom successively, solid plate 4, moving platen 3, cushion block 2 and Bottom clamp plate 1, solid plate 4 is provided with cover half benevolence 12, moving platen 3 is provided with mavable module core 16, cover half benevolence 12 perisporiums are provided with all first heating tanks 17, the front side wall of mavable module core 16 and left and right sides wall are provided with second heating tank 19, be placed with the first heating wire rod 18 and with 10 embeddings of first copper bar tightly and fill and lead up first heating tank 17 in first heating tank 17, be placed with the second heating wire rod 20 and with 13 embeddings of second copper bar tightly and fill and lead up second heating tank 19 in second heating tank 19, the two ends of the first heating wire rod 18 are equipped with the first plug wire head 11, the two ends of the second heating wire rod 20 are equipped with the second plug wire head 14, solid plate 4 is provided with open slot 8, be stamped first gland 9 on the open slot 8, first gland 9 is connected with solid plate 4 by screw, the first plug wire head 11 is positioned at open slot 8, moving platen 3 is provided with groove 6, be stamped second gland 7 on the groove 6, second gland 7 is connected with moving platen 3 by screw, the second plug wire head 14 is positioned at groove 6, moving platen 3 is provided with two cable-through holes 15 that communicate with groove 6, and cable-through hole 15 is used for external power cord to be passed through.

Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
