Description

TECHNICAL FIELD

[0001] The utility model relates to a production workshop auxiliary tool's technical field, specifically relates to a lower mould special trolley. BACKGROUND

[0002] At present, four moulds for producing cake baking tray are placed on the punch, and it needs to spend a lot of time to install and adjust the mould every time the mould is replaced, and the installer needs to climb up and down on the very high punch, and it is very tired, in order to quickly install the mould, four lower moulds are fixed on a large steel plate now, only the position of the steel plate needs to be adjusted, so that the installation requirements of the four lower moulds can be guaranteed, thereby the time for installing and adjusting the mould when replacing the mould is saved. However, the steel plate is very heavy, and four lower moulds are added, so it is impossible to lift the steel plate by hand and place it on the lower mould table of the punch for installing the lower mould, since the spacing between the upper and lower mould tables of the punch is limited, and the lower mould table has precision requirements, so that the scheme of moving the steel plate by a forklift cannot be realized. At present, an auxiliary tool for transferring the steel plate fixed with four lower moulds is needed. SUMMARY

[0003] The utility model solves the technical problem that a lower mould special trolley can transfer the steel plate fixed with four lower moulds to the platform of the punch, can pull the steel plate back to the frame, and can also transfer the steel plate to other places.

[0004] The technical solution for achieving the purpose of the utility model is as follows: a lower mould special trolley, characterized by comprising a frame, a wheel set arranged at the lower part of the frame, and a telescopic supporting leg, and a push-pull assembly, a platform for placing the steel plate and two slide rails respectively located at both ends of the platform are arranged above the frame, the push-pull assembly comprises a push block and a linear actuator which can drive the push block to reciprocate and is arranged in parallel with the slide rails, the movable end of the linear actuator is connected with the push block, and the two ends of the push block are connected with the slide rails in a sliding mode.

[0005] The push block is provided with a through hole.

[0006] The linear actuator is an oil cylinder, an electric push rod or a gas cylinder.

[0007] The supporting leg comprises a supporting leg and a supporting leg linear actuator which can drive the supporting leg to reciprocate, and the movable end of the supporting leg linear actuator is connected with the supporting leg.

[0008] The supporting leg linear actuator is an oil cylinder, an electric push rod or a gas cylinder.

[0009] The platform comprises a plurality of roller shafts arranged side by side and perpendicular to the slide rails.

[0010] The utility model is a special trolley for lower molds, which has the following beneficial effects: the steel plate is pushed onto the lower mold table of the punch press or the steel plate is pulled back from the lower mold table of the punch press onto the trolley through the linear actuator, thereby reducing the workload of workers in moving the steel plate and the mold; the steel plate can be easily moved to other places for placement by arranging the wheel set; the height of the supporting feet can be adjusted to make the platform and the lower mold table of the punch press at the same horizontal position, while ensuring that the wheel set is off the ground and the frame will not move easily. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is described in detail below with reference to the accompanying drawings and embodiments;

[0012] Fig. 1 It is a structural diagram of the utility model;

[0013] Fig. 2 It is a structural schematic diagram of the utility model from another angle. DETAILED DESCRIPTION

[0014] like Figs. 1-2 As shown, the lower mold cart comprises a frame 1, a wheel set 2 and retractable support legs 3 disposed at the bottom of the frame 1, and a push-pull assembly. A platform 1.1 for placing steel plates is located above the frame 1, along with two slide rails 1.2 located at either end of the platform 1.1. The platform 1.1 comprises a plurality of arranged shafts. The push-pull assembly includes a push block 4 and a linear actuator 5 that drives the push block 4 in reciprocating motion and is arranged parallel to the slide rails 1.2. The movable end 5.1 of the linear actuator 5 is connected to the push block 4, and the push block 4 is slidably connected to the slide rails 1.2 at both ends.

[0015] The push block 4 is provided with a through hole 4.1. This facilitates connecting the push block 4 to the steel plate, thereby allowing the steel plate to be pulled from the lower die table of the punch press onto the platform 1.1. This is accomplished by providing a detachable connector on the side wall of the steel plate, which can be connected to the connector by a chain or strap, etc., passing through the through hole 4.1.

[0016] The linear actuator 5 can be an oil cylinder, an electric push rod or an air cylinder. If an oil cylinder is adopted, a piston type oil cylinder is preferably adopted.

[0017] The support leg 3 comprises a support leg linear actuator 3.1 and a support leg 3.2, wherein the movable end 3.1.1 of the support leg linear actuator 3.1 is connected to the support leg 3.2.

[0018] The support leg linear actuator 3.1 can be a cylinder, an electric push rod or a pneumatic cylinder. If a cylinder is used, a plunger cylinder is preferably used.

[0019] The platform 1.1 may be made into another structure, for example, the platform 1.1 includes a plurality of rollers placed side by side and perpendicular to the slide rail 1.2 (schematic diagram not shown).

[0020] Usage status:

[0021] Push the lower mold cart with the steel plate next to the punch press and position it so the plate is in the correct position. Hydraulically drive the linear actuator 3.1 to adjust the height of the support leg 3, thereby adjusting the height of the lower mold cart so that the wheel assembly 2 is off the ground. Simultaneously, adjust the support leg 3 to align the platform 1.1 with the lower mold table of the punch press. Secure the lower mold cart to the punch press with chains, straps, or other auxiliary tools to prevent the cart from moving during operation.

[0022] When installing a steel plate, the movable end 5.1 of the linear actuator 5 is pushed outward, driving the push block 4 to push the steel plate onto the lower die table of the punch press. When unloading the steel plate, the steel plate is connected to the push block 4, and the linear actuator 5 retracts the extended movable end 5.1, thereby driving the push block 4 to pull the steel plate from the lower die table of the punch press back onto the platform 1.1.
