The connecting seat core pulling block 54 is obliquely arranged, and the upper die holder 1 is slidably arranged to facilitate demoulding. The oil outlet pipe core extracting rod 542 is arranged on the connecting seat core extracting block 54 to realize one-step molding of the connecting seat and the oil outlet pipe. The oil outlet pipe core drawing bar 542 is arranged on the connecting seat, so that the structure is simple, the processing difficulty of the connecting seat is reduced by independently arranging the oil outlet pipe core drawing bar 542, the processing cost is reduced, the die maintenance and die repair are convenient, and the use cost is reduced.
The fixed hole core pulling column 522 and the kettle bottom side die core 52 are integrally formed, so that burrs on the surface of the fixed hole are prevented from affecting the installation of the oil kettle.
The positioning hole core pulling rod 532, the oil return pipe core pulling rod 534 and the oil return pipe forming insert 535 reduce the processing difficulty of the mold core 53 at the oil return side of the kettle bottom, reduce the processing cost, facilitate the maintenance and repair of the mold, and realize the reduction of the use cost.
The return tube core rod 534, the return tube forming insert 535, the return tube upper half die 512 and the return tube lower half die 560 achieve the return tube forming, simplifying the structure of the die.
The sliding mold separating device and the pneumatic mold separating device respectively realize mold separation of the kettle bottom side mold core 52 and the kettle bottom oil return side mold core 53.
The communicating hole forming at the bottom of the oil receiving pipe is realized by adopting the communicating hole core drawing rod 553, so that secondary processing is avoided, one-step forming is realized, and the production cost of the kettle bottom is reduced.
Because the mold core has high strength and high processing precision, the mold core 52 at the bottom side of the kettle and the mold core 53 at the oil return side of the kettle bottom are movably inserted into the mold core groove 513 at the bottom side of the kettle to realize accurate positioning, thereby ensuring the stability of the cavity.
If two half molds are matched with the mold cores 55 under the kettle bottom, positioning grooves with higher precision are required to be processed in the upper mold plate 2 and the lower mold plate 3 or positioning devices with high precision are required to be installed, so that the position is prevented from shifting in the injection molding process, the mold structure is complicated, the strength requirements on the upper mold plate 2 and the lower mold plate 3 are high, the volumes and the weights of the upper mold plate 2 and the lower mold plate 3 are large, the material cost is high, and the processing cost is greatly increased.
The demolding is realized by controlling the opening sequence of the mold, so that the structure of the mold is simplified, and the use of auxiliary devices is reduced.
The sliding plate 541 and the chute cover plate realize the fixation of the connection seat core pulling block 54. The chute cover prevents the connecting seat core block 54 from ejecting out of the slide slot 16 during the mold closing process.

The connecting seat core-pulling block 54 is in sliding fit with the core-pulling block seat 24, so that lifting and guiding of the connecting seat core-pulling block 54 are realized. Because the loose core block seat 24 is small in size, convenient to process, processing cost can be reduced, high-precision inclined holes are prevented from being processed on the upper template 2, meanwhile, friction force generated by inclined lifting is borne by the loose core block seat 24, the inclined drawing holes of the connecting seat are prevented from being borne, the service life of the inclined drawing holes of the connecting seat is prolonged, maintenance time is shortened, use cost is reduced, and the stability of the die is improved.
The inclined guide rod ascends along with the upper die plate 2, the inclined guide rod pushes the side die slide blocks to the two sides of the die, and the side die slide blocks drive the kettle bottom side die core 52 and the kettle bottom oil return side die core 53 to be separated.
When the upper die plate 2 descends to be clamped, the pressing inclined surface of the upper die plate 2 pushes the sliding inclined surface, the side die sliding block slides towards the inside of the die, and the pot bottom side die core 52 and the pot bottom oil return side die core 53 are clamped.
If the upper die holder 1 cannot be lifted firstly, the connecting seat core pulling block 54 and the oil outlet pipe core pulling rod 542 can pull the kettle bottom, and the sequential lifting of the upper die holder 1 and the upper die plate 2 is ensured through the die opening sequence control device.
