Description

Technical Field

[0001] The utility model relates to a mould, in particular to a shell mould. Background Art

[0002] Figure 1 A housing is shown in the figure, comprising a main body 100, on which a baffle 101 extending upward is provided, and through holes 102 are provided on both end surfaces of the baffle 101.

[0003] This product is very troublesome to demould due to the presence of two through holes. The conventional method is to set two plug rods on the mold and insert them into the pipe to form a through hole. When demoulding, the two plug rods also need to use a special driving mechanism to withdraw from the through hole. For this reason, a special driving mechanism is required for each plug rod, which makes the mold very complicated. Therefore, it is necessary to improve it. Summary of the invention

[0004] The utility model aims to provide a shell mold, the mold structure of which is greatly simplified.

When in use, we first pull the lower mold plate downward to drive the guide block to move downward, at this time, the sliding block slidably connected to the slide groove of the guide block will move outward, drive the plug rod to be pulled out of the cavity, at this time, the plug rod will not affect the demoulding, and then pull the upper mold upward to complete the demoulding of the product. The mold of this structure can complete demoulding without setting a left and right core pulling driving structure, and the mold structure is greatly simplified.

[0006] In the above technical solution, preferably, there are two guide mechanisms, which are respectively arranged on two opposite end surfaces of the mold.

[0007] In the above technical solution, preferably, the lower mold includes a lower mold core and a lower outer frame, the lower outer frame is arranged on the outer side of the lower mold core, the sliding block is slidably connected to the lower outer frame, and the insertion rod is arranged in the lower mold core.

[0008] In the above technical solution, preferably, positioning blocks are provided at both ends of the lower mold frame, and the positioning blocks are provided with slots, and the guide blocks are inserted into the slots.

[0009] In the above technical solution, preferably, the upper mold includes an upper mold core and an upper outer frame, and the upper outer frame is arranged on the outer side of the upper mold core.

[0010] In the above technical solution, preferably, cooling water channels are provided on the upper mold core and the lower mold core.

[0011] The utility model has at least the following beneficial effects: when in use, we first pull the lower mold plate downward to drive the guide block to move downward, at which time the sliding block slidably connected to the guide block's slide slot will move outward, driving the insertion rod to be pulled out of the rear cavity, and at this time the insertion rod will not affect demoulding, and then the upper mold is pulled upward to complete the demoulding of the product. This structure of the mold can complete demoulding without setting a left and right core pulling drive structure, and the mold structure is greatly simplified. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 2-4 A shell mold comprises an upper mold 1 and a lower mold 2, wherein a cavity 1a formed by the upper mold 1 and the lower mold 2 after the upper mold 1 and the lower mold 2 are combined forms an outer wall of the shell.

[0018] The upper mold 1 includes an upper mold core 11 and an upper outer frame 12 , and the upper outer frame 12 is arranged on the outer side of the upper mold core 11 .

[0019] The lower mold 2 includes a lower mold core 21 and a lower outer frame 22. The lower outer frame 22 is arranged on the outer side of the lower mold core 21. The lower end of the lower mold 2 has a lower mold plate 3. The lower mold plate 3 is provided with several columns. The lower mold 2 is slidably connected to the columns.

[0020] The mold further comprises a guide mechanism 4, wherein two guide mechanisms 4 are provided, respectively disposed on two opposite end surfaces of the mold.
