Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a lower mold base structure of a mold. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting and stamping. Generally, moulds are composed of upper and lower mould bases. In addition to processing, the lower mould base also plays a guiding and supporting role for the upper mould base.

[0003] After the existing lower die base completes processing, the processed product is generally ejected through a jacking structure. For example, a tray forming mold with a jacking mechanism disclosed in announcement number CN218660309U can achieve rapid separation through the jacking structure. However, when the processed product has many special-shaped surfaces and the overall cross-section is large, stable and effective jacking cannot be achieved by relying solely on a single jacking structure. The current method is to use multiple jacking columns to achieve jacking. Although jacking can be achieved, it is difficult to set up and layout in the early stage, and it is also necessary to open multiple through holes on the lower die base for the placement and movement of the jacking columns. The processing is time-consuming and difficult, so there are great limitations in actual use. Utility Model Content

[0004] The utility model aims to provide a lower die seat structure of a mold to solve the problem of inconvenient operation in ejecting products with special-shaped surfaces and large cross-sections proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lower die base structure of a mold, including a bottom plate, with a die base block installed on the top thereof; also including a lifting assembly; the lifting assembly is composed of a lifting part and a supporting part, wherein the supporting part cover is arranged on the top of the die base block and fits with the top of the die base block; the lifting part is placed inside the die base block, and its top end is abutted against the four inner corners of the supporting part, and the supporting part is lifted upward by the lifting part to realize the lifting work, and the supporting part is used to support and bear the weight of the processed product; the supporting part is a lifting cover, and separation grooves are provided at both ends of the lifting cover, and the separation grooves are used to facilitate the separation and removal of the processed products at a later time. It is worth noting that the area of ​​the separation groove is not the area where the product needs to be processed, so as to avoid the problem of processing failure.

[0006] Preferably, a punch is formed on the top of the die base block, and a fitting with the punch is formed on the inner side of the bottom end surface of the lifting cover. By achieving fit with the punch, normal stamping processing in the later stage is ensured, and at the same time, the entire shaped product can be lifted.

[0007] Preferably, through holes are provided at the four corners of the die base block; the lifting part includes a lifting column inserted into the through hole, and a lifting spring arranged between the lifting column and the through hole, and the lifting column is lifted up by the rebound of the lifting spring. When the lifting column is lifted up, the lifting cover will be lifted up. At this time, the separation groove is hollow, and the products can be separated. In normal stamping, the lifting column and the lifting cover can be lowered by the compression of the lifting spring.

[0008] Preferably, the bottom of the lifting cover is wrapped around the outside of the die base block, so as to facilitate the alignment and installation of the die base block and the lifting cover, and to ensure vertical lifting in the later stamping and lifting.

[0009] Preferably, a placement groove is opened at the top edge of the mold base block, and a plurality of balls are placed in the placement groove. The balls are rollingly connected to the inner side surface of the lifting cover, so as to reduce the friction of the lifting cover during lifting.

[0010] Preferably, the cross-section of the ball coincides with the front surface of the mold base block, that is, the ball does not protrude outside the placement groove, while being able to achieve a rolling connection with the lifting cover. A limiting bolt is screwed into the inner wall of the placement groove near the opening, and the limiting bolt abuts against the ball at the top position, thereby limiting the ball and preventing it from falling out of the placement groove.

[0011] Preferably, guide pillars are installed at the four corners of the top surface of the bottom plate, and buffer springs are sleeved on the guide pillars for buffering when contacting the upper die seat.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The designed lifting component can fit with various special-shaped products to achieve the function of rapid lifting, greatly reducing the tedious operations of opening and grooving the mold and simplifying the structure of the mold. At the same time, in normal punching processing, the lifting component and the lower die base are formed as one, which will not cause any impact on the processing and improve the shortcomings of the existing lower die base in lifting.
